PURPOSE: A cooling/heating system for generating hot water using a heat pump is provided to produce only hot water when a cooling/heating process is not performed. CONSTITUTION: A cooling/heating system for generating hot water using a heat pump comprises a compressor, a first heat exchanger(10), a second heat exchanger(60), a loading unit(80), an expansion valve(90), a third heat exchanger(110), a terrestrial heat exchanger(100), and a multi-way valve(40). The compressor compresses refrigerant. The first heat exchanger connects to compressor through a first circulating pipe(20) and produces hot water with heat exchange. The second heat exchanger is formed in a second circulating pipe(50) connected to the first circulating pipe. The loading unit connects to the second heat exchanger through the third circulating pipe(70) for cooling and heating processes. The expansion valve is formed in the second circulating pipe. The third heat exchanger is formed in the second circulating pipe. The terrestrial heat exchanger connects to the third heat exchanger through a fourth circulating pipe(120). |
