Abstract: An air conditioning and heat pump tower includes a main casing, a plurality of connecting pipes, a compressor, a front heat exchanger, a rear heat exchanger, a fan unit, and an energy efficient arrangement. The energy efficient arrangement includes a first pre-heating heat exchanger supported in a front compartment of the main casing, and positioned between an outdoor air intake opening and an outdoor heat exchanging portion of the front heat exchanger. The air conditioning and heat pump tower may be operated between an air conditioning mode for absorbing heat from the indoor space, and a heat pump mode for producing heat to the indoor space. A predetermined amount of ambient air may be drawn through the outdoor air intake opening and may be pre-heated by the energy efficient arrangement before delivering to the indoor space.

Abstract: There is provided a vehicle air conditioning apparatus that can prevent the amount of the refrigerant discharged from the compressor from reducing when an outside air temperature is low to achieve a heating performance required for a heating operation, and also can dehumidify the vehicle interior without deteriorating the heating performance during a heating and dehumidifying operation. The vehicle air conditioning apparatus includes: a heat released refrigerant expansion valve that decompresses the refrigerant discharged from the radiator during the heating operation and the first heating and dehumidifying operation; a gas-liquid separator that separates the refrigerant decompressed by the heat released refrigerant expansion valve into a gaseous refrigerant and a liquid refrigerant; and a bypass circuit that allows part of at least the gaseous refrigerant separated in the gas-liquid separator to flow into a section of the compressor through which the refrigerant being decompressed passes.

Abstract: Provided is a refrigeration apparatus which can reduce outlet pressure of a refrigerator even in overload conditions and which can improve refrigeration capacity by liquefying a refrigerant in an intermediate cooler. When outlet pressure of a refrigerator 2 is higher than critical pressure, a control apparatus 60 performs control to reduce the opening degree of a decompression electric valve 31 at the upstream side of an intermediate cooler 30. Thereby, the refrigerant is liquefied by gas-liquid separation in the intermediate cooler 30, so that the refrigerator outlet pressure is made less than the critical pressure, and the liquid refrigerant can be sent to a showcase 3. As a result, the specific enthalpy of the refrigerant at the inlet side of main diaphragm means 41 of the showcase 3 can be reduced, and thereby, the cooling effect can be increased.

Abstract: A plate heat exchanger includes a plurality of rectangular plates each having, at four corners thereof, inlets and outlets and others for a first fluid and a second fluid. The plates are stacked such that first passages each defined by adjacent two of the plates and through which the first fluid flows and second passages each defined by adjacent two of the plates and through which the second fluid flows are provided alternately. The first passage includes a bypass passage extending from an inlet peripheral portion, which is an area around the inlet, along the outlet for the second fluid up to a long-side-peripheral portion of the plate that is nearer to the second outlet. The bypass passage allows some of the first fluid having flowed therein from the inlet to flow from the long-side-peripheral portion into a heat-exchanging passage.
