摘要： Disclosed herein is a heating device including a controller (90) configured to switch operation modes of the heating device from a first mode to a second mode, or vice versa. The first mode of operation includes an operation of allowing, while a heat source unit (20) is running, a heating medium heated by a heating heat exchanger (31) to flow through a heat storage tank (52) and then return to the heating heat exchanger (31). The second mode of operation includes an operation of allowing, while the heat source unit (20) is not running, the heating medium in the heat storage tank (52) to flow through an air-heating heat exchanger (51), be bypassed around the heating heat exchanger (31), and then return to the heat storage tank (52).

摘要： A refrigeration apparatus is provided in which compression efficiency can be improved and the heating of water for a hot water supply can be made more efficient. The refrigeration apparatus is a water heater (1) for treating water in a water circuit (910) having a water inlet tube (901) for leading water supplied from the exterior to a water branching point (W), heat source water tubes (902, 903) and intermediate water tubes (904, 905) extending from the water branching point (W), and a water outlet tube (906) leading to the exterior from a convergent point (Z) where the heat source water tubes (902, 903) and the intermediate water tubes (904, 905) converge; wherein an intercooler (7) performs heat exchange between refrigerant passing through an intermediate refrigerant tube (22) leading from a low-stage side to a high-stage side, and water flowing through the intermediate water tubes (904, 905). A heat source-side heat exchanger (4) subjects refrigerant passing through a connecting tube (72) for connecting a discharge side of a high-stage compression element (2d) and an expansion mechanism (5) to heat exchange with water flowing through the heat source water tubes (902, 903) without subjecting the refrigerant to heat exchange with water flowing through the water inlet tube (901).

摘要： To provide, in a refrigerating apparatus using a refrigerant that works including a process of a supercritical state, a refrigerating apparatus whose coefficient of performance can be improved while maintaining device reliability even when its load fluctuates. A heat source-side heat exchanger (4) is connected to a discharge side of a high stage-side compression element (2d), and connecting pipes (72, 73, 74, 75) interconnect the heat source-side heat exchanger (4) and an expansion mechanism (5). Connecting pipes (77, 2a) interconnect a utilization-side heat exchanger (6) and a suction side of a low stage-side compression element (2c). A liquid-gas heat exchanger (8) causes heat exchange to be performed between the refrigerant flowing through the connecting pipes (72, 73, 74, 75) and the refrigerant flowing through the connecting pipes (77, 2a). A liquid-gas three-way valve (8C) switches between a state where it allows the refrigerant to flow in portions of the connecting pipes (72, 73, 74, 75) passing through the liquid-gas heat exchanger (8) and a state where it allows the refrigerant to flow in a liquid-gas bypass pipe (8B) that interconnects one end side and the other end side of the portions passing through the liquid-gas heat exchanger (8).
