What is the reason why the evaporation temperature is too low?
Of the high-pressure refrigerant vapor directly into the evaporator, so that the evaporation pressure to a normal level.
In order to prevent the evaporation temperature is too low, the cold and dry machine set the energy bypass protection, when the refrigerant evaporation pressure is low to a certain value, for the heat to add the hot gas bypass valve automatically open (opening increased), the condenser
, Such as the production of "liquid compression", so that the gas blockage, resulting in a significant decline in the compressor cooling coefficient, energy consumption, etc. Therefore, a large temperature of compressed air into the cold and dry work, the refrigerant in the tube evaporation temperature should at least ensure
4. The cooling system piping has a chronic leak, if the evaporation temperature drops very low, so that the surface temperature of the heat exchange brass below zero, the water vapor will be condensed into the surface of the copper tube, the refrigeration system will bring many adverse consequences
