How does the thermal expansion valve match the evaporator?
(Oil cooler load will increase) If the thermal expansion valve selection is too large will lead to suction zone fluid, the unit easy to liquid hit.
7, the choice of thermal expansion valve is very important, if the heat expansion valve selection is too small will lead to inspiratory superheat, the evaporator heat transfer area can not be effectively used, the compressor suction heat caused by a certain row of heat
Thermostatic expansion valve selection Under normal circumstances, depending on whether the evaporator load fluctuations (small fluctuations in 130% evaporator load configuration, fluctuations in accordance with the 170% evaporator load configuration) but pay attention to check the following aspects:
In general, the load of the evaporator is to be configured according to the 130% chiller load.
