Abstract:
A compound evaporation device for supplying cold air to a cold room and comprising:a) a compressor for circulating a gaseous refrigerant; b) an outdoor condenser having an inlet connected to an outlet of the compressor whereby gaseous refrigerant circulates through the outdoor condenser and is condensed into a liquid; c) an evaporator in the cold room having an inlet, and an outlet connected to an inlet of the compressor, the evaporator having a plurality of heat guide fins; d) a serpentine re-condenser tube located adjacent to the outlet of the evaporator in heat exchange relationship with the plurality of heat guide fins, and connected to an outlet of the outdoor condenser so as to pass liquid refrigerant therethrough; and e) an atomizing device having an inlet connected to the serpentine re-condenser tube to convert liquid refrigerant from the serpentine re-condenser tube into gaseous refrigerant, the atomizing device having an outlet connected to the inlet of the evaporator such that gaseous refrigerant passes through the evaporator, whereby heat from the re-condenser tube maintains the refrigerant in gaseous form upon exit from the evaporator and entrance into the inlet of the compressor to reduce power consumption of the compressor.
