<p>A heat pump system (1) is capable of simultaneous cooling and heating operations and is composed of usage units (5a, 5b) for performing an air-cooling operation and an air-warming operation using an aqueous medium, the usage units being connected to a heat source unit (2) having heat-source-side heat exchangers (26a, 26b). The heat pump system (1) operates so that the heat-source-side condensing temperature (Tc1s) is below 40°C in the case that an outside air temperature is 25°C or lower and the cooling and heating operations coexist.</p> |
