Application
The function of the economiser is to cool the liquid refrigerant (subcooling) from the condenser
before it is led to the evaporator. The flash gas side is connected to the economiser port of the
screw compressor, where the intermediate pressure gas from SVER is added to the suction gas.
The liquid will be subcooled to improve the efficiency of the refrigeration plant.
Product Description
By connecting the economiser to the economiser port of the compressor, gas of intermediate
pressure is led to the compressor resulting in increased COP. The refrigeration capacity of the
economiser appears as subcooling of the liquid from the high-pressure side to the low-pressure
side of the refrigeration plant.
