摘要： A compressor, a radiator, an expander, and an evaporator are connected in series to define a refrigerating cycle. A bypass circuit that bypasses the expander, an on-off valve disposed in the bypass circuit, and a controller C1 for controlling an opening of the on-off valve are provided in the refrigerating cycle. During defrosting, the controller C1 controls the on-off valve so that a refrigerant may flow through the bypass circuit, thereby avoiding reduction in the amount of flow of the refrigerant during defrosting and preventing the defrosting operation from being prolonged.

摘要： A heat pump of the present invention has a compressor and an expander coupled with a common axis of rotation, a first throttling device disposed in a circulation passage of refrigerant, and a second throttling device disposed in a bypass passage diverted from the expander. A control device controls the openings of these throttling devices. The control device executes a first controlling in which the opening of the first throttling device is adjusted in order to bring a high pressure PH in a refrigeration cycle close to a predetermined value determined based on a value at which the coefficient of performance (COP) of the heat pump is optimized, and after the first controlling is completed, it executes a second controlling in which the opening of the second throttling device is adjusted in order to bring a degree of superheat SH close to a predetermined positive value. This ensures smooth and stable operations of the heat pump.

摘要： It has been difficult to operate a drying apparatus in a stable and high-efficiency state where a superheat value is changed in a drying process. A drying apparatus includes: a first temperature sensor 38 which detects the temperature of a refrigerant between the outlet of an evaporator 34 and the inlet of a compressor 31; and control means 14 for controlling a superheat value by changing flow resistance of an expansion valve 33 based on a detected value of the first temperature sensor 38. The control means 14 controls the superheat value in the drying process to become a target value.

摘要： A refrigeration cycle apparatus includes a compressor, a radiator, an expander, an evaporator, a bypass circuit, and an injection circuit. The bypass circuit has a flow rate control valve and a gas-liquid separator. One end of the bypass circuit is connected to an intake conduit of the expander and the other end thereof is connected to a discharge conduit of the expander so that a portion of refrigerant passed through the radiator bypasses the expander and is guided to the flow rate control valve and that the liquid refrigerant separated by the gas-liquid separator returns to the discharge conduit of the expander. One end of the injection circuit is connected to a gas outlet portion of the gas-liquid separator and the other end thereof is connected to an intermediate pressure portion of the compressor.
