Abstract
The invention relates to vapor compressing refrigeration system and its purpose it is mainly consisted of a compressor, a four-way electromagnetic direction valve with or without installing, a condenser, a device for drying and filtering, a stop valve, a boiler, and a vapor liquid separator. It is characterized in that: at the internal of system between the device for drying and filtering and the stop valve there is setting up a sub cooler which can make the liquid refrigerating medium temperature fall from the condensation to the evaporation and then to evaporate accordingly increase the refrigerating coefficient of the refrigerating equipment; and make the producing heat equipment increased the heat supplying coefficient so it can either save the energy or deduce the discharging. It is suited to the cold-warm air conditioning especially in heat pump water heater, heat pump boiled machine, drying house, cold storage, ice chest, refrigerator, and cooler. And the other characteristic of it is that in the vapor compressing refrigeration system with or without installing the sub cooler it connects with two or three thermal converters in paralleling by one or two couple tee branch electromagnetic directional valves in order to assemble the refrigeration and the producing thermal equipments and shares one compressor or outdoor machine and so on. One machine can be used in multiple functions so it can save the primary material and reduce the total manufacturing cost.
