PURPOSE: A cool and hot water supplying device for heating and cooling which is a hybrid heat-pump type is provided to obtain the high efficiency hot water than normal heat pump using electricity energy. CONSTITUTION: A cool and hot water supplying device for heating and cooling which is a hybrid heat-pump type comprises a compressor(10), a first heat exchanger(20), a expansion valve(30-1, 30-2), a second heat exchanger(40) and a third heat exchanger. The compressor compresses the refrigerant to the high pressure and high temperature. The first heat exchanger, expansion valve and the second heat exchanger are composed in order that the refrigerant is circulated with compressor. The third heat exchanger is installed between the first heat exchanger and expansion valve and divides the refrigerant which is discharged in the first heat exchanger to the first refrigerant and the second refrigerant. The first refrigerant is provided to the expansion valve and the second refrigerant is restored with the first refrigerant which passes through the second heat exchanger is evaporated in the compressor without the contact of the second heat exchanger. |
