PURPOSE: A cooling and heating device using a heat pump is provided to heat a house in the night by storing underground heat and inner heat of the house and using the stored heat. CONSTITUTION: A cooling and heating device(10) using a heat pump comprises multiple heat exchangers(11), a heat storage tank(14), a heat pump(30), and a first auxiliary heat supply unit(50). The heat exchangers are installed inside a house and emit and absorb heat. The heat storage tank is connected to a first supply pipe(12) and a first return pipe(13). The heat pump has a first heat exchanger(32), a second heat exchanger(34), a circulation pipe(35), and a four-way valve(38). The first and second heat exchangers are installed in first and second heat exchanging chambers(31,33). The first auxiliary heat supply unit is connected to the second heat exchanging chamber. |
