Position of evaporator in screw chiller unit

When the evaporator of the water-cooled screw chiller is located below the condenser or reservoir, and there is no solenoid valve on the liquid pipeline, the pipeline should be sealed in an inverted "U" shape with a height of not less than 2000mm. Multiple evaporators are placed on top of the condenser or accumulator. The end of the defrosting cycle of the screw chiller can also be carried out according to the signal of the program relay. But in this case, most defrost cycles are longer or shorter than the required time. The second scenario is not allowed as it can cause a rapid decrease in cooling capacity, while in the first scenario, both heating and subsequent cooling of the refrigeration chamber require more energy consumption and increase temperature fluctuations.
Therefore, when the temperature on the surface of the evaporator of an industrial chiller rises above the melting point of frost, the system that sends out the defrost end signal is a more complete system.
