-1- Liquid return problem   1, expansion valve factors: liquid return problems are often related to the selection and improper use of expansion valves. Excessive selection of expansion valve, improper setting of superheat, incorrect installation of temperature sensing bag or damaged insulation wrap, and failure of expansion valve may lead to liquid return phenomenon. 2, liquid amount control: For the use of small capillary refrigeration system, excessive liquid will also cause liquid return. 3, evaporator and fan: evaporator frost serious or fan failure caused by poor heat transfer, non-evaporating liquid will lead to liquid return. 4, temperature fluctuations: frequent fluctuations in the temperature of the cold storage may also lead to the failure of the expansion valve response, which in turn leads to liquid return.   -2- Startup problem with liquid   Phenomenon description When the return air cooled compressor is started, the phenomenon of severe foaming of lubricating oil in the crankcase is called liquid starting. Cause analysis The root cause of starting with liquid is that a large amount of refrigerant is dissolved or deposited in the lubricating oil, which suddenly boils and causes the foaming of the lubricating oil when the pressure is suddenly reduced. Refrigerant migration After the compressor is shut down, the refrigerant in the evaporator will enter the crankcase in a "refrigerant migration" mode, resulting in a liquid start.     -3- Oil return problem   1, oil return bend design: when the compressor position is higher than the evaporator, the oil return bend on the vertical return pipe is necessary, and should be compact design to reduce oil storage. 2, variable load system: In the variable load system, special attention needs to be paid to the oil return problem under low load, which can be solved by using measures such as double risers. 3, compressor start-up and operation: frequent start-up is not conducive to oil return, so frequent start-up should be avoided, and appropriate measures should be taken to ensure oil return.   -4- Evaporation temperature, return air temperature, return air pressure   Effect of evaporation temperature The increase of evaporation temperature will significantly increase the motor load, while the decrease of evaporation temperature will reduce the refrigerant mass flow, and the motor power demand will be correspondingly reduced. The relationship between return temperature and evaporation temperature The degree of return air temperature is relative to the evaporation temperature, and a reasonable return air temperature is very important for the efficient operation of the system.   -5- Exhaust temperature, exhaust pressure, exhaust volume   Excessive exhaust temperature The main reasons include high return temperature, high motor heating, high compression ratio, high condensing pressure, adiabatic index of refrigerant and improper refrigerant selection. Taking the R22 compressor as an example, when the evaporation temperature is reduced from -5 ° C to -40 ° C, the COP will be significantly reduced, and the temperature rise of the gas in the motor cavity may be increased several times. Therefore, reducing the evaporation temperature will directly lead to a significant increase in the exhaust temperature. Air cooled compressor The exhaust temperature is closely related to the compression ratio (condensing pressure/evaporation pressure). The larger the compression ratio, the higher the exhaust temperature, the less refrigeration capacity of the compressor, and the more power consumption. Reducing the compression ratio can be achieved by increasing the suction pressure or reducing the exhaust pressure. The effect of compression ratio Optimized workflow, resulting in a 30% increase in operational efficiency. New policies were implemented to improve team collaboration and communication. New products were launched and received positive feedback in the market.   Exhaust pressure Excessive exhaust pressure is mainly caused by excessive condensing pressure, which may be caused by excessive air in the system, excessive refrigerant, and poor heat dissipation of the condenser. Maintaining an appropriate condensing area and cooling medium flow rate is critical. underexhaust It is mainly related to compressor design volume, suction pipe length and pipe diameter. Too long pipe and too small pipe diameter will increase the suction resistance, affect the suction volume, and thus reduce the exhaust volume.    

What are the real reasons for compressor frosting Frosting at the return air port of a cold storage compressor is a common phenomenon in refrigeration systems.Piston type Compressor Unit Generally, it does not immediately cause system problems,Screw type Compressor Unit and minor frosting generally does not need to be addressed. If the phenomenon of frost formation is severe, the first step is to understand the cause of frost formation. Air Cooled type Condenser Unit Frost formation at the compressor return port: Frost on the return air port indicates that the return air temperature of the compressor is too low. So what situation can cause the return air temperature of the compressor to be too low? Water Cooled type Condenser Unit If the volume and pressure of refrigerant of the same quality are changed, Evaporator Unit the temperature will have different performance. If the return air temperature of the compressor is low, it generally shows both low return air pressure and high refrigerant volume of the same volume. Mobile Cold Room The root cause of this situation is that the refrigerant flowing through the evaporator cannot fully absorb the heat required to expand to the predetermined pressure and temperature value. Refrigeration Project and Construction 1. The supply of liquid refrigerant to the throttle valve is normal, but the evaporator cannot absorb heat properly; There are two factors that can cause this problem: 2. The evaporator is working normally to absorb heat, but the refrigerant supply to the throttle valve is too high, which means that the refrigerant flow rate is too high. We usually understand it as having too much refrigerant. Due to the lack of fluorine, the compressor return air is frosted: 1. Due to the extremely low flow rate of refrigerant. Insufficient refrigerant expansion will not utilize the entire evaporator area, but will only form low temperatures locally in the evaporator. In some areas, rapid expansion due to insufficient refrigerant will cause local temperatures to be too low, leading to frost formation in the evaporator. After partial frost formation, due to the formation of an insulation layer on the surface of the evaporator and the low heat exchange in that area, the refrigerant expansion is transferred to other areas, gradually causing the entire evaporator to frost or freeze. The entire evaporator forms an insulation layer, and then the expansion spreads to the compressor return pipe, causing the compressor return air to frost. 2. Due to the insufficient amount of refrigerant. The low evaporation pressure of the evaporator leads to a low evaporation temperature, which gradually causes condensation in the evaporator to form an insulation layer, and transfers the expansion point to the compressor return air, causing the compressor return air to frost. Both of the above points will show evaporator frost before the compressor return air frosts. In fact, in most cases, for frost phenomenon, just adjust the hot air bypass valve. Specific method: Open the rear end cover of the hot air bypass valve, and then use an No. 8 hex wrench to turn the adjusting nut clockwise. The adjustment process should not be too fast. Generally, pause for about half a turn, let the system run for a period of time, and then check the frost situation before deciding whether to continue the adjustment. After the operation is stable and the frost phenomenon of the compressor disappears, tighten the end cover. Frosting at the cylinder head (severe crankcase frosting): Frosting at the cylinder head is caused by a large amount of wet steam or refrigerant being sucked into the compressor. The main reasons for this situation are: 1. The opening of the thermal expansion valve is adjusted too large, causing the installation of the temperature sensing package to be incorrect or loose, resulting in the sensing temperature being too high and causing the valve core to open abnormally. The thermal expansion valve is a direct acting proportional regulator that uses the superheat at the outlet of the evaporator as a feedback signal, compares it with a given superheat value, and generates a deviation signal to regulate the refrigerant flow entering the evaporator. It integrates a transmitter, regulator, and actuator. According to different balancing methods, thermal expansion valves can be divided into two types: internal balancing thermal expansion valves and external balancing thermal expansion valves. The opening of the thermal expansion valve is adjusted too large, the installation of the temperature sensing package is incorrect or the fixing is loose, resulting in the sensing temperature being too high and causing the valve core to open abnormally, causing a large amount of wet steam to be sucked into the compressor and leading to frost formation at the cylinder head. If the superheat at the outlet of the evaporator is too high, the overheated section at the rear of the evaporator will be too long, and the cooling capacity will be significantly reduced; If the outlet superheat is too low, it may cause compressor liquid hammer or even frost on the cylinder head. It is generally believed that the expansion valve should be adjusted to a working superheat of 3 ℃ to 8 ℃ at the outlet of the evaporator. 2. The expansion valve is not tightly closed when the supply solenoid valve leaks or shuts down. Causing a large amount of refrigerant liquid to accumulate in the evaporator before startup. This situation can also easily cause compressor fluid shock! 3. There is too much refrigerant in the system. The liquid level in the condenser is higher, the condensation heat exchange area is reduced, and the condensation pressure increases. That is, the pressure in front of the expansion valve increases, and the amount of refrigerant flowing into the evaporator increases. The liquid refrigerant cannot completely evaporate in the evaporator. Therefore, the compressor sucks in wet steam, causing the cylinder head to cool or even frost, and may cause "liquid hammer". At the same time, the evaporation pressure will also be higher.

Typical Breakdown Analysis of Rotor Refrigeration Condensing Unit Characteristics of rotor refrigeration compressors: The rotary compressor consists of three main parts: motor, mechanical part, Piston type Compressor Unit and shell part. It is mostly used in refrigerators, household air conditioners, and small refrigeration equipment. Generally, Screw type Compressor Unit the rotary compressor is used below 6 horsepower. Characteristics of rotary compressors: fewer components and simple structure; Less vulnerable parts, reliable operation; Under the same cooling capacity, the compressor has a small volume,Air Cooled type Condenser Unit light weight, and balanced operation; No suction valve plate, low resistance, and low suction overheating; Small clearance volume and high gas transmission coefficient; High machining accuracy requirements; Water Cooled type Condenser Unit The sealing line is long, the sealing performance is poor, and the leakage loss is significant; The torque peak of a single cylinder is large and needs to be balanced.Evaporator Unit Stator components, rotor components, cylinders, slides, rolling pistons, main bearings, auxiliary bearings, crankshaft, upper housing components, lower housing, main housing, frame components, Mobile Cold Room and base components.

Maintenance of Cold Storage Cold Room 1. After the new installation or long-term shutdown of the cold storage and refrigeration equipment, comprehensive testing and debugging should be carried out before reuse. Under the guidance of professional refrigeration technicians, it can be started and used only when all indicators are normal. Piston type Compressor Unit 2. Attention should be paid to the collision and scratching of hard objects on the cold storage body and outer body during use. Because it can cause dents and rust, and in severe cases, Screw type Compressor Unit it can lead to a decrease in local insulation performance. 3. Due to the fact that prefabricated cold storage is composed of several insulation boards, there are certain gaps between the boards. During construction, these gaps will be sealed with sealant to prevent air and moisture from entering.Air Cooled type Condenser Unit So, in use, timely repair some sealing failure parts. We must resolutely prevent the occurrence of cold escape. 4. Generally, insulation boards are used for the floor of small prefabricated cold storage. When using a cold storage, a large amount of ice and water should be avoided on the ground. Water Cooled type Condenser Unit If there is ice, hard objects should not be used to knock or damage the ground during cleaning. 5. Initial operation of the unit: It is necessary to regularly observe the oil level and return oil situation of the compressor, as well as the cleanliness of the oil. Evaporator UnitIf oil dirt or oil level drop is found, it should be promptly resolved to avoid poor lubrication. 6. Regularly clean the air cooler to maintain good heat exchange. Check if the motor and fan rotate flexibly. If there is any blockage, lubricating oil should be added; If there is abnormal friction sound, the bearings of the same model and specification should be replaced to clean the dirt on the fan blades, coils, and water accumulation plates. For the cold air unit, it is necessary to regularly check the condenser. If there is scaling problem, it should be promptly removed. Mobile Cold Room 7. For evaporators: it is necessary to regularly check the defrosting situation. Whether defrosting is timely and effective can affect the refrigeration effect, leading to liquid return in the refrigeration system. 8. Regularly observe the operating status of the compressor; Check its exhaust temperature. During seasonal operation, pay special attention to the operating status of the system and adjust the system's liquid supply and condensation temperature in a timely manner. 9. Carefully listen to the sound of the compressor and condenser fan during operation, promptly handle any abnormalities, and check the vibration of the compressor, exhaust pipe, and foundation. Check if the compressor has any abnormal odor.Refrigeration Project and Construction 10. In the initial stage, the internal cleanliness of the system was poor, and the refrigeration oil needs to be replaced after 30 days of operation. For systems with high cleanliness, it should be thoroughly replaced after six months of operation (depending on the actual situation). 11. The refrigeration technician conducts an annual inspection and maintenance of the compressor. Check the oil level and color of the compressor. If the oil level is lower than 1/2 of the sight glass, the cause of the oil leakage should be identified and the fault should be eliminated before filling with lubricating oil; If the oil has changed color, the lubricating oil should be thoroughly replaced. Check if there is air in the refrigeration system, and if so, discharge the air. 12. Regularly check and confirm whether the voltage of the power supply meets the requirements, and the voltage should be 380V ± 10% (three-phase four wire). When the cold storage equipment is not in use for a long time, the main power supply of the fresh-keeping cold storage should be cut off, and the cold storage equipment should be ensured not to be damp or contaminated by other substances such as dust. 13. Regularly check whether the connecting pipes and valves of the refrigeration unit are secure and whether there is refrigerant leakage (oil stains usually appear in the leaking areas).

How to add refrigerant to the condensing unit? The working procedure for adding refrigerant to the refrigeration system of the unit should be carried out after the vacuum pumping of the refrigeration system is completed, Piston type Compressor Unit in order to prevent air infiltration caused by internal vacuum in the system.Screw type Compressor Unit Before adding refrigerant to the refrigeration system of the unit, the circuit of the solenoid valve in the system should be connected to keep it open. The first time refrigerant is added, liquid refrigerant should be added from the filling port on the high-pressure valve or reservoir of the unit.Air Cooled type Condenser Unit If conditions permit, a drying filter can be installed on the filling pipe between the unit and the Freon cylinder to prevent moisture and impurities in the refrigerant from entering the system.Water Cooled type Condenser Unit The initial refrigerant filling amount can be 80% of the rated value required by the refrigeration system, and the initial filling amount should not be too much.Evaporator Unit For large refrigeration systems, after filling, the unit should stand still for about 30 minutes. After the internal pressure of the standby refrigeration system stabilizes, the compressor can be started to run (for water-cooled units, the cooling water system should be started first), and the operation status of the refrigerant can be observed. Generally, the flow status of the refrigerant can be observed from the system's sight glass to determine whether the refrigerant filling amount is appropriate. If the refrigerant is insufficient, You can add an appropriate amount of gaseous refrigerant from the low-pressure detection port until the bubbles in the sight glass disappear, the evaporator is filled with even frost, and the compressor return pipe is covered with thin frost, which can determine the appropriate amount of refrigerant added to the refrigeration system.Mobile Cold Room In most cases of cold storage refrigeration systems, gaseous or liquid refrigerant can be filled from the low-pressure side. When the refrigerant filling amount is large, liquid refrigerant filling method can also be used from the high-pressure side. Attention required! If filling liquid refrigerant from the low-pressure side, be sure to add it slowly to avoid liquid shock! If you are afraid of liquid impact, gas filling can also be used.Refrigeration Project and Construction Method of adding refrigerant from the low-pressure side: When filling gaseous refrigerant from the low-pressure side, first rotate the low-pressure three-way shut-off valve counterclockwise to the endpoint, then connect the fluorine filling tube of the fluorine bottle to the bypass screw seat of the low-pressure three-way shut-off valve. Then, open the bottle valve of the R22 fluorine bottle, slightly loosen the joint of the bypass screw seat of the three-way shut-off valve, use R22 gas to drive out the air in the fluorine filling tube, and immediately lock it when you hear a "sizzling" airflow sound at the joint, Refrigerant charging begins. After the injection amount reaches the specified quality, close the fluorine bottle shut-off valve, rotate the low-pressure three-way shut-off valve counterclockwise to the endpoint, close the bottle valve of the R22 fluorine bottle, remove the fluorine adding tube, and the fluorine adding work is completed.

Why does the refrigeration system of a cold storage emphasize the need for vacuum pumping? Let's first take a look at the composition of air, as shown in the following figure. Nitrogen accounts for 78%, oxygen accounts for 21%, and other gases account for 1%. What are the effects of these gas components on the refrigeration system after entering it?Piston type Compressor Unit The impact of nitrogen in the air on the system: Firstly, we need to know that nitrogen is a non condensable gas. The so-called non condensable gas refers to the gas circulating in the system with the refrigerant, not condensing with the refrigerant, and not producing a refrigeration effect.Screw type Compressor Unit The presence of non condensable gases poses great harm to refrigeration systems, mainly manifested in the increase of system condensation pressure, condensation temperature, compressor exhaust temperature, and power consumption. Nitrogen enters the evaporator and cannot evaporate with the refrigerant; It will also occupy the heat exchange area of the evaporator, preventing the refrigerant from fully evaporating and reducing the refrigeration efficiency; At the same time, high exhaust temperature may cause carbonization of lubricating oil, affecting lubrication efficiency, and in severe cases, burning out the refrigeration compressor motor. The impact of oxygen in the air on the system: Oxygen, like nitrogen, is also a non condensable gas. We have already analyzed the hazards of non condensable gases, and we will not repeat them here. However, it is worth noting that compared to nitrogen, if oxygen enters the refrigeration system, there are still these hazards: Oxygen in the air will react chemically with the refrigeration oil in the refrigeration system to produce organic compounds, which eventually form impurities and enter the refrigeration system, causing adverse consequences such as dirt and blockage.Air Cooled type Condenser Unit Oxygen can easily react with refrigerants, water vapor, and other substances to form acids, causing oxidation of the refrigeration oil. These acids can damage various components of the refrigeration system and damage the insulation layer of the motor; At the same time, these acid products will remain in the refrigeration system without any problems at first, but over time, they will eventually cause damage to the compressor. The following image illustrates these issues very well.Water Cooled type Condenser Unit The impact of other gases on the refrigeration system: Water vapor affects the normal operation of refrigeration systems, with the smallest solubility in Freon liquids, and the solubility gradually decreases as the temperature decreases. The most intuitive effects of water vapor on refrigeration systems are as follows, which we will illustrate in graphic form: There is water in the refrigeration system, and the first impact is on the throttling structure. When water vapor enters the throttling mechanism, the temperature rapidly decreases and the water reaches the freezing point, causing ice to form, blocking the small through-holes of the throttling structure and causing ice blockage.Evaporator Unit Corrosion of pipeline water vapor entering the refrigeration system increases the water content of the system, causing corrosion and blockage of pipelines and equipment.Mobile Cold Room Generate sediment and sludge. During the compression process of the compressor, water vapor encounters high temperatures and produces a series of chemical reactions with refrigeration oil, refrigerant, organic matter, etc., resulting in damage to the motor winding, metal corrosion, and the formation of sludge deposits.Refrigeration Project and Construction In summary, in order to ensure the effectiveness of refrigeration equipment and extend its lifespan, it is necessary to ensure that the refrigeration system is free of air. Therefore, the correct method is to exclude air from the system. In the practical application process of refrigeration systems, deposits and corrosion can cause blockage and failure of expansion valves, filter dryers, and filters. The only reliable way to remove water vapor from the air in the refrigeration system is to take the correct operating steps and use a deep vacuum pump. For newly installed units, a vacuum pump must be used to vacuum the entire refrigeration system. It is not allowed to use the compressor of this unit to vacuum the system, otherwise it may cause irreparable damage to the compressor.

The refrigerant quota plan is about to be implemented, and the refrigerated industry is expected to return to its business cycle Recently, the Ministry of Ecology and Environment of China issued the "2024 Total Quota Setting and Allocation Plan for Hydrofluorocarbons" (hereinafter referred to as the "Plan"), Piston type Compressor Unit which clarifies the total quota for domestic HFCs production,refrigerator import, and domestic use next year, Screw type Compressor Unit as well as the allocation plan for enterprise quotas. Air Cooled type Condenser Unit Cold storage is usually divided into three temperatures: high temperature, medium low temperature, and ultra-low temperature. Different ingredients require different temperatures. The selection of cold storage panels is very important for cold storage, as cold storage is different from other warehouses and requires high temperature, humidity, and other environmental factors. So when selecting cold storage boards, attention should be paid to the raw materials and insulation strength of the boards. Choosing the right board can effectively protect the cold storage.
