What are the effects of excessively high temperature when exhausting industrial chillers How to solve

The exhaust temperature of the compressor in an industrial chiller determines whether the equipment can operate stably and efficiently. The compressor is prone to excessive exhaust temperature. Once this occurs, it is easy to increase the pressure of the industrial chiller. Excessive high temperature, high temperature, high load, reduced operating efficiency and cooling capacity of industrial chiller compressors can also cause various other problems.

　　 First of all, the exhaust temperature is too high will cause the condenser working efficiency of the industrial chiller to decrease. There are many reasons for the excessively high exhaust temperature. For example, if the flow of cooling water is not enough or the water temperature is too high for a long time, the exhaust temperature will be too high. Once the compressor's exhaust temperature is too high, work efficiency will be problematic. In addition, after the high-temperature gas is discharged to the condenser, the condenser cannot completely cool the refrigerant, and liquid accumulation may occur. After a long time of use, the working efficiency of the condenser will decrease. Correspondingly, when the working efficiency of the condenser decreases, it will also Affect the working efficiency of the compressor.

　　Secondly, the suction pressure is low and the suction heat is high. When the exhaust temperature is too high, the suction temperature will be correspondingly higher, and because the compressor discharge temperature is higher, it can be inferred that the compressor of the compressor is larger. This is because the suction pressure must be lower when inhaling. , You can reduce the compression ratio to reduce the exhaust temperature and exhaust pressure.

According to the above-mentioned effects and causes of excessive exhaust temperature, it can be known that if you want to reduce the exhaust temperature of industrial chillers, you can cool the compressor. The editor of okmarts.com suggests that you can choose the following methods to solve the problem .

　　1. Increase the cooling water flow and the heat dissipation and ventilation of the water tank and water tower.

The cooling water in the water tank of the air-cooled industrial chiller and the cooling water tower of the water-cooled industrial chiller exists for the cooling and heat exchange of the condenser. It can take away the heat generated by the compressor. If the cooling water flow and wind The cooling and ventilation capacity of the cold industrial chiller water tank and the water-cooled industrial chiller water tower can keep the cooling water temperature within a limited range to maximize the cooling of the compressor.

　　2, directly reduce the discharge temperature of the refrigeration compressor.

The so-called direct reduction of the compressor discharge temperature can start from reducing the compression ratio of the compressor, reducing the load, etc. Although reducing the compression ratio will make the efficiency of the compressor lower, it can solve the problem of excessive compressor discharge temperature. problem.

　　 3. Reasonable use of refrigerant.

　　 At the same evaporating temperature and condensing temperature, different types of refrigerants have different exhaust temperatures. In addition to the common R22, there are also refrigerant types such as R134a. Users should add different refrigerants according to the requirements of industrial chiller manufacturers.
