    • The present invention relates to a heat pump system and an operation method of the heat pump system and, more specifically, to a heat pump system comprising a compressor, a ventilator, an outdoor coil, a heat exchanger, an expansion valve, and a plurality of outdoor units. The compressor discharges high-temperature and high-pressure refrigerant. The outdoor coil exchanges heat with outside air. The heat exchange discharges hot water or cool water by enabling a coolant to exchange the heat with the refrigerant. A plurality of outdoor units comprises coolant pipes by connecting the compressor, the outdoor coil, and the heat exchanger and operates in a cooling cycle or a heating cycle according to each load condition. Each outdoor unit facilitates an individual operation and a simultaneous operation by comprising independent coolant circuit. The heat pump system defrosts a part of outdoor units through a reverse cycle operation and facilitates defrosting and continuous heating without a complex additional coolant circuit and a control method. The heat pump system facilitates cooling and heating by using two three-way valves at the same time regardless of a defrosting operation. The heat pump system supplies the hot water and the cool water.
