Abstract: The internal heat exchanger 7 is provided which exchanges heat between the refrigerant of low pressure and the refrigerant of high pressure, and the pre-load adjusting mechanism of the expansion valve 5 is abolished. Due to the above structure, the refrigerant flowing into the expansion valve 5 is cooled in the internal heat exchanger 7, and enthalpy of the refrigerant flowing into the evaporator 6 is reduced. On the contrary, the refrigerant sucked into the compressor 1 is heated. Accordingly, a difference in enthalpy between the refrigerant at the inlet and the refrigerant at the outlet of the evaporator 6 can be made large, and the heat absorbing capacity of the evaporator 6 can be enhanced, and further it becomes possible to give the degree of superheat to the refrigerant sucked into the compressor 1. Therefore, even if the pre-load adjusting mechanism is abolished, the vapor-compression-type refrigerating machine can be stably operated.

Abstract: A refrigerant cycle system includes a first heat-exchanging portion for condensing gas refrigerant discharged from a compressor, a gas-liquid separator into which all of refrigerant after passing through the first heat-exchanging portion and a part of gas refrigerant discharged from the compressor are introduced, and a second heat-exchanging portion for cooling and condensing refrigerant flowing from the gas-liquid separator. Because all of the condensed refrigerant from the first heat-exchanging portion is introduced into the gas-liquid separator, a passage area of a gas refrigerant introduction passage for introducing gas refrigerant from the compressor into the gas-liquid separator can be set relatively large. Therefore, a dimension difference of the gas refrigerant introducing passage in manufacturing is not greatly affected to an adjustment of a liquid refrigerant amount in the gas-liquid separator.

Abstract: A refrigeration cycle for a vehicle air conditioning system allows the refrigerant-to-refrigerant heat exchanger to exchange heat between a high-pressure liquid refrigerant, which is delivered from the sub-cooling condenser and directed to the evaporator, and a low-pressure refrigerant having a liquid and gas phase, which is delivered from the evaporator and directed to the compressor. The refrigeration cycle also allows the amount of the refrigerant circulating through the refrigeration cycle to be adjusted in response to the level of sub-cooling upstream of a throttle hole of a reverse sub-cooling control valve to thereby indirectly control the level of superheating on the outlet side of the evaporator. This provides improvements both in the amount of heat to be exchanged between refrigerants in the refrigerant-to-refrigerant heat exchanger and the cooling performance of the evaporator.

Abstract: A first heat exchange unit is for condensing a refrigerant discharged from a compressor. A second heat exchange unit is provided downstream from the first heat exchange unit. A gas-liquid separator, into which part of the refrigerant from the compressor and part of the refrigerant from the first exchange unit flow, is for separating the refrigerants into a gas and a liquid refrigerant to accumulate the liquid refrigerant. The gas refrigerant in the separator is lead to the second heat exchange unit. A primary refrigerant flow path, included in the first heat exchange unit, is for leading the refrigerant to the second heat exchange unit. A branch refrigerant flow path, included in the first heat exchange unit and independently partitioned from the primary refrigerant flow path, is for leading the refrigerant to the separator.

Abstract: A color card showing at least three color samples is provided. Among the color samples, a light color sample expressing a light color tone occupies a larger space than samples expressing the other color tones. A deep color sample expressing a deep color tone in the color card is arranged on one side of the light color sample, and a neutral color sample expressing a neutral color tone which stands between the light and deep color tones is arranged on the other side. Use of such a color card allows the user to roughly select a color card showing a color tone suited for being applied to an object to be painted from a plurality of color cards based on their light color samples, and then select one of color tones shown in the selected color card.

Abstract: An expansion valve unit having a pressure detecting function includes a supercooling control expansion valve disposed in a flow path of a refrigerant sent into an evaporator of a refrigeration system constituting a refrigerating cycle to control the flow rate of the refrigerant. A pressure detector is provided at one end of the supercooling control expansion valve to detect the pressure of the refrigerant sent thereto through a passage in the expansion valve.
