Abstract
A vapor compressed air conditioning or refrigeration equipment includes an accumulator connected between the high pressure side of the compressor and, the inlet of the condenser; a flow-rate control unit is provided at the outlet of the accumulator. Also provided is a dipped type heat exchanger device disposed at the high pressure side of the compressor and connected between the compressor and the condenser via refrigerant pipes and a submersible heat dissipated tube. The dipped type heat exchanger includes a container for storing a heat transfer medium for heat exchange with a waste heat recycled tube combined with the container in heat transfer relationship. The tube is disposed between the low-pressure side of the air conditioning equipment and the compressor, for the purpose of reducing the temperature of the heat transfer medium and thus reducing the temperature of the high temperature superheated refrigerant vapor within the submersible heat dissipated tube.
