20100000245 | AIR CONDITIONING APPARATUS - An air conditioning apparatus is filled with a supercritical refrigerant, and includes a compression mechanism, a radiator, an expansion mechanism, an evaporator, a first temperature detector, a target refrigerant temperature derivation unit, and a control unit. The target refrigerant temperature derivation unit uses at least a set temperature to determine a target refrigerant temperature, the set temperature being a temperature that is set relative to the air in the space in which the radiator is disposed, and the target refrigerant temperature being the target temperature of the refrigerant flowing between the outlet side of the radiator and the refrigerant inflow side of the expansion mechanism. The control unit controls the expansion mechanism so that the temperature detected by the first temperature detector corresponds to the target refrigerant temperature. | 01-07-2010 |

20110002803 | EXPANDER - An expander includes a cylinder at which an inflow port and an outflow port are formed, a piston eccentrically disposed in the cylinder relative to a rotational shaft to form a fluid chamber between the piston and the cylinder, and a blade dividing the fluid chamber into a high pressure side and a low pressure side. The cylinder, the piston and the blade are arranged and configured such that the expander recovers power of a fluid depressurized in the fluid chamber. The cylinder has an inner diameter Dc, the inflow port has a diameter Di, and the outflow port has a diameter Do. The relationship 0.065×Dc≦Di≦0.13×Dc and/or 0.065×Dc≦Do≦0.13×Dc is satisfied. | 01-06-2011 |
20110005270 | REFRIGERATION APPARATUS - A refrigeration apparatus includes a compression mechanism, a heat source-side heat exchanger, a usage-side heat exchanger, a switching mechanism and an intermediate heat exchanger. Refrigerant discharged from a first-stage compression element is sequentially compressed by a second-stage compression element. Each of the heat source-side heat exchanger and the usage-side heat exchanger functions an evaporator or radiator. The switching mechanism is configured to switch between a cooling operation state and a heating operation state. The intermediate heat exchanger is configured to cool refrigerant discharged from the first-stage compression element and drawn into the second-stage compression element when the switching mechanism has been set to the cooling operation state, and to evaporate refrigerant whose heat is radiated in the usage-side heat exchanger when the switching mechanism has been set to the heating operation state. | 01-13-2011 |
20130025307 | REFRIGERATION SYSTEM - A refrigeration system includes a refrigerant circuit including a compressor and an expander which expands a refrigerant and generates power, for performing a refrigeration cycle. The refrigeration system includes a compressor control section and an expander control section which, when an operation stop signal is output during operation, reduces a rotational speed of the compressor and increases a rotational speed of the expander to increase the ratio of the rotational speed of the expander to the rotational speed of the compressor. | 01-31-2013 |
