The use of the refrigerant

1, refrigerant selection requirements 1. 1, the working temperature and working pressure refrigerant wants moderate under atmospheric pressure, the refrigerant evaporation temperature is low enough, with snow kind of meet the requirements of the temperature of the cooling; At room temperature, the refrigerant should have lower condensing pressure, because the condensing pressure too high sealing performance of the refrigeration system agent structure strength requirement is high. General requirements of the refrigerant condensing pressure is: 12 x 105 ~ 15 x 105 Pa; At room temperature, the refrigerant evaporation pressure have higher disposable cylinders, because if the pressure inside the evaporator is lower than the atmospheric pressure, the air easily through the gap into the refrigeration system of the outside world, make the pressure in the system, reduce the refrigerating capacity, increase power consumption. At the same time the refrigerants in air moisture will cause the refrigeration system to produce ice wall and other consequences. 2. 2, should have larger refrigerant refrigerating capacity refrigeration equipment of the same specification, the unit volume was elected with the refrigerant units volumetric refrigerating capacity is big, can obtain larger refrigerating capacity. Under the same conditions, when the capacity must be unit volume of refrigerant refrigerating capacity is big, can reduce the refrigerant volume of the system, and also can be corresponding to shrink the size of the compressor. 3. Three critical temperature is higher, refrigerant, freezing point lower critical temperature is high, easy to refrigerant said in ambient temperature condensate liquid. Low freezing point, low temperature, can be produced to expand the use of refrigerant temperature range, reduce the throttling loss, improve the refrigeration coefficient. 4. 4, refrigerant, viscosity and density to small viscosity and density is small, can make the system in the refrigerant cycle, small flow resistance, reduce the cycle of energy consumption, appropriate to reduce the pipe size, and allows for a smaller pipe bending radius ( And this is very important to reduce the evaporator pressure loss) , but also can reduce the chiller to the impact of the compressor valve group, prolong the service life of the compressor. 5. 5, refrigerant, coefficient of thermal conductivity and heat release coefficient of thermal conductivity and heat release coefficient is high, can reduce the structure of the heat exchanger in refrigeration system appropriately, and can improve the thermal efficiency of heat exchanger in. 6. 6, other aspects of refrigerant request not burning, not explode, non-toxic, non-corrosive, affordable, easy to buy. 2, the classification of refrigerants, refrigerant according to the size of the condensing pressure under normal temperature and evaporating temperature under atmospheric pressure, can be divided into three broad categories: 2. 1, high temperature low pressure refrigerant evaporation temperature above 0 ℃, condensing pressure lower than that of 29. 41995×104Pa。 2. 2, in the medium voltage temperature refrigerant evaporation temperature - 50 ~ 0 ℃, condensing pressure ( 196. 113-29. 41995). ×104Pa。 2. 3, high pressure refrigerant evaporation temperature below - at low temperature 50 ℃, the condensing pressure is higher than 196. 133×104Pa。
