Abstract: A refrigeration cycle apparatus includes an indoor heat exchanger, a water heat exchanger, a pump, an outdoor heat exchanger, a compressor, an expansion valve, a four-way valve, a third pipe, and an open/close valve, and configured to enable hot-gas defrosting and reverse cycle defrosting. A controller selects, based on the indoor load, either one of the hot-gas defrosting and the reverse cycle defrosting to be performed. In this way, defrosting can be performed with a minimum decrease of the chiller water temperature.

Abstract: An air-conditioning apparatus includes; a first heat source device configured to transfer heat to process air using as a heat source a vapor-compression refrigeration cycle; a second heat source device configured to transfer heat to the process air using an other heat source different from the vapor-compression refrigeration cycle; and a controller configured to control the first heat source device and the second heat source device. The controller deactivates the first heat source device and activates the second heat source device when, during a period in which the first heat source device is being operated to heat the process air, a temperature of the heated process air is kept at a target temperature and a parameter indicating an energy consumption of the first heat source device exceeds a first threshold value.

Abstract: A heat pump water heater includes: a compressor; a first water-refrigerant heat exchanger; a second water-refrigerant heat exchanger; refrigerant paths capable of forming a refrigerant circuit; and water channels including a flow channel, the flow channel leading hot water that has passed through the second water-refrigerant heat exchanger to the first water-refrigerant heat exchanger. The heat pump water heater is able to perform a heating operation. In the heating operation, the hot water heated in the second water-refrigerant heat exchanger is fed to the first water-refrigerant heat exchanger and the hot water further heated in the first water-refrigerant heat exchanger is supplied to a downstream side of the water channels. The first water-refrigerant heat exchanger is able to be replaced without replacing the second water-refrigerant heat exchanger.

Abstract: An air conditioning device has: a refrigerant circuit that includes a compressor, a switching valve, a cascade heat exchanger, an expansion valve and an outdoor heat exchanger connected to one another by a first pipe through which a refrigerant flows, and that performs a defrosting operation in which the refrigerant discharged from the compressor is introduced into the outdoor heat exchanger; a heat-transfer medium circuit that includes a pump, the cascade heat exchanger, and the indoor heat exchanger connected to one another by a second pipe through which a heat-transfer medium flows; and a control device that controls the compressor and the pump. When an amount of heat storage of the heat-transfer medium is less than a threshold, the control device reduces the heating capability of the indoor heat exchanger when the air conditioning device transitions from a heating operation to the defrosting operation.

Abstract: Each of plural temperature adjustment apparatuses variably adjusts the amount of heat exchange between an inflow medium, which is a liquid medium supplied to a corresponding indoor heat exchanger, and an outflow medium, which is a liquid medium discharged from the corresponding indoor heat exchanger. Each of the plural temperature adjustment apparatuses reduces the heat exchanging capacity of the corresponding indoor heat exchanger by increasing the amount of heat exchange between the inflow medium and the outflow medium when the heat exchanging capacity of the corresponding indoor heat exchanger is larger than the indoor load. When there is no temperature adjustment apparatus in which the amount of heat exchange between the inflow medium and the outflow medium is set to the minimum, the heat source apparatus reduces the heating capacity or the cooling capacity for changing the temperature of the liquid medium.

Abstract: A temperature adjustment apparatus adjusts a temperature of a heating medium that exchanges heat with air in an indoor heat exchanger connected to a heat source apparatus. It includes a first and second pipes through which the heating medium flows, the second pipe being branched into a first and second branch pipes which are thereafter merged, a second heat exchanger in which heat is exchanged between the heating medium in the first branch pipe and the heating medium in the first pipe, and a flow rate regulator that changes a flow rate of the heating medium in the first branch pipe and a flow rate of the heating medium in the second branch pipe. The second pipe supplies the heating medium from the heat source apparatus to the indoor heat exchanger. The first pipe returns the heating medium from the indoor heat exchanger to the heat source apparatus.
