Abstract: A heat pump system may include a compressor, a water-refrigerant heat exchanger, an expansion valve, an outdoor heat exchanger, an outlet temperature sensor configured to detect an outlet temperature of the water-refrigerant heat exchanger, an outside temperature sensor, a discharge pressure sensor, a suction pressure sensor, and at least one processor. The at least one processor may obtain, during a heating operation, a first target discharge temperature of the compressor based on an output value from the outlet temperature sensor and an output value from the outside temperature sensor, obtain a second target discharge temperature of the compressor based on an output value from the discharge pressure sensor and an output value from the suction pressure sensor, set any one of the first target discharge temperature or the second target discharge temperature to a final target discharge temperature, and control the expansion valve based on the final target discharge temperature.

Abstract: A heat pump performs a simultaneous air-conditioning and heating operation through the addition of a flow path switching apparatus. The heat pump may include a plurality of outdoor units, a plurality of indoor units, and a plurality of flow path switching apparatuses that switch a flow path between an outdoor unit and an indoor unit. A refrigerant flow path may be formed from the outdoor unit to the indoor unit via a high-pressure gas pipe. The flow path switching apparatuses may switch a flow path so that a refrigerant flow path is formed from the indoor unit to the outdoor unit via a low-pressure gas pipe. The heat pump may further include an indoor unit mode controller that is connected to the plurality of outdoor units through a liquid pipe, and which is connected to each of the plurality of flow path switching apparatuses.
