Abstract: A heat pump system may include: a compressor configured to compress a refrigerant; a refrigerant-water heat exchanger configured to perform heat exchange between the compressed refrigerant and inlet water; an expansion valve configured to expand the refrigerant condensed in the refrigerant-water heat exchanger; an outdoor heat exchanger configured to perform heat exchange between the refrigerant expanded in the expansion valve and outdoor air; a high pressure sensor configured to detect a high pressure saturation temperature of the refrigerant compressed in the compressor; an inlet water temperature sensor configured to detect a temperature of water flowing into the refrigerant-water heat exchanger; a condensation temperature sensor configured to detect a temperature of the refrigerant condensed in the refrigerant-water heat exchanger; an outdoor temperature sensor configured to detect an outdoor temperature; and a controller including at least one processor, comprising processing circuitry, individually and/or collectively, configured to: determine a reference supercooling degree of the refrigerant based on detection of outdoor temperature by the outdoor temperature sensor and inlet water temperature by the inlet water temperature sensor and an operating frequency of the compressor, determine a current degree of supercooling of the refrigerant based on detection of pressure saturation temperature by the high pressure sensor and condensation temperature by the condensation temperature sensor, and determine whether the refrigerant leaks by comparing the reference supercooling degree and the current degree of supercooling.

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.
