PURPOSE: A cool water supply system using a heat pump is provided to select a refrigerant circuit which does not need a 4-way valve and to make the operation smooth in the low temperature. CONSTITUTION: An evaporator(F,G) and a condenser(B,C) are integrated and installed in an outdoor coil type air heat exchanger. High temperature discharge gas passes a plane heat exchanger(H) from a compressor in order to generate hot water. The high temperature discharge gas is condensed in the evaporator of the outdoor coil type air heat exchanger and helps the evaporation of the refrigerant gas swelled in the evaporator. The discharge gas is frozen and flows in a liquid receiver.
