AIR CONDITIONING SYSTEM WITH USE OF HEAT PUMP AND CONTROL METHOD OF ABOVE SYSTEM Russian patent published in 2011 - IPC F25B30/02 

FIELD: power industry.

SUBSTANCE: air conditioning system has four-way valve, heat exchanger and control, which are located indoors, control and heat exchanger, which are located outdoors, and which are connected in series to each other so that circuit is formed. Compressor steam-jet system includes compressor which has the first gas inlet hole, the second gas inlet hole and gas outlet hole. The first gas inlet hole is connected to four-way valve by means of gas-water separator. The second gas inlet hole is connected by means of bypass tube on which electrical expansion valve is located to indoor located control and outdoor located control. Gas outlet hole is connected to four-way valve. Indoor control is in-series connected by means of fluid tank to outdoor control. Bypass tube is located between indoor control and fluid tank and has the coil located inside fluid tank. Gas condition sensors are located at the first gas inlet hole, the second gas inlet hole and gas outlet hole. Depending on sensor readings the pressure of the second gas inlet hole of compressor is regulated so that volume of cooling agent jet can be maintained at optimum level.

EFFECT: higher heating capacity and efficiency of used energy at low ambient air.
