This is a well-known configuration commonly used in air conditioners and the like, in which refrigerant sucked into the cylindrical cylinder 12 is compressed between the vane 14 and a discharge valve 15 when the pressure reaches a certain pressure.

A discharge valve 15 of the compressor 10 is connected to one end of an outer heat exchanger 16 such as a water-cooled or air-cooled condenser housed in the housing case 9.
The high-temperature and high-pressure vaporized refrigerant compressed by the compressor 10 is cooled by the outer heat exchanger 16 and liquefied and condensed.

A four-way switching valve 17 is connected between the compressor 10, the garment-side heat exchanger 7, and the outer heat exchanger 16 as a bypass for circulating the refrigerant flow in the normal and reverse directions. By switching the flow direction of the refrigerant by the switching valve 17, switching between the cooling operation cycle (see FIG. 2) and the heating operation cycle (see FIG. 3) can be easily performed.

The other end of the outer heat exchanger 16 is connected to a refrigerant passage 18.
The tubing 5 for refrigerant of the garment-side heat exchanger 7 is attached to one part of the garment main body 1, for example, the flank side or the back side.
The liquefied refrigerant is connected to an expansion valve 19 or a capillary tube communicating with the other end to reduce the pressure of the liquefied refrigerant, and
It is sent to the clothes side heat exchanger 7 inside.

The expansion valve 19 and the outer heat exchanger 16, the garment-side heat exchanger 7 and the switching valve 17, and the refrigerant flow passages 8 and
Reference numeral 18 denotes a clothes body 1 and a storage case 9 as shown in FIG.
Are arranged in a longer connecting pipe 20 connected between them, so that the place where the storage case 9 is placed on the clothing body 1 can be freely changed.

In this embodiment, each of the compressor 10, the outer heat exchanger 16, and the switching valve 17 is housed in an electrically driven or engine driven removable or portable storage case 9. Although not shown in the drawings, the expansion valve 19 together with the compressor 10, the outer heat exchanger 16, and the switching valve 17 are also housed in an electrically driven or engine driven removable or portable storage case 9, so that the clothes-side heat is removed. The refrigerant pipes 8, 18 of the exchanger 7 and the expansion valve 10, the garment-side heat exchanger 7, the switching valve 17, and the compressor 10, respectively, are connected inside the communication pipe 20 connecting the garment body 1 and the storage case 9. It is good also as what was included in.

Next, an example of use and operation of the embodiment configured as described above will be described. First, as shown in FIG. 2, the clothes main body 1 is used in a cooling operation so as to be in a cooling state. In the case, the clothes side heat exchanger 7 → compressor 1
0 → Outside heat exchanger 16 → Expansion valve 19 → Clothing side heat exchanger 7
The switching valve 17 is previously switched to the cooling operation cycle side so that the order of the flow paths is as follows. The liquefied refrigerant absorbs the heat of the outside air and takes away the heat of evaporation from the clothes-side heat exchanger 7 contained in the garment body 1 having adiabatic heat retention and cooling properties, and the liquefied refrigerant evaporates and the gas temperature is lower than that of the outside air. It becomes a vaporized refrigerant at about 3 ° C. This vaporized refrigerant is sent to a compressor 10 housed in a storage case 9 through a refrigerant flow path 8 contained in a communication pipe 20, where the vaporized refrigerant is, for example, at a temperature of about 80 ° C. and a pressure of about 3.
Compress to 5 times higher temperature and pressure.

The high-temperature and high-pressure vaporized refrigerant compressed and heated by the compressor 10 is sent to the outer heat exchanger 16 stored in the storage case 9, where the high-temperature and high-pressure vaporized refrigerant is cooled and liquefied and condensed. That is, the refrigerant takes heat from the surroundings at the clothes-side heat exchanger 7 and is discarded by the air flowing through the outer heat exchanger 16 in the case of the air-cooling type at the outer heat exchanger 16, for example. Alternatively, in the case of the water-cooled type, the heat is discarded into the water flowing in the outer heat exchanger 16.

The refrigerant liquefied by the outer heat exchanger 16 is decompressed and cooled to a low temperature through an expansion valve 19 or a capillary tube provided for separating a high pressure section and a low pressure section in a cooling operation cycle. Since it is sent into the clothes-side heat exchanger 7 in the main body 1 and evaporates while taking away the heat of the air in the main body 1, at the same time, the latent heat of evaporation is also absorbed from around the main body 1 to lower the temperature in the main body 1. is there. Thereafter, the cooling operation is repeated in the same manner.

On the other hand, when the garment body 1 is used in a heating operation so as to be in a heating state, as shown in FIG. 3, the outer heat exchanger 16 → the compressor 10 → the garment side heat exchanger 7 → the expansion valve 19, as shown in FIG. → The switching valve 17 is previously switched to the heating operation cycle side so that the flow path of the outer heat exchanger 16 is in order. The liquefied refrigerant removes the heat of the outside air from the outer heat exchanger 16 stored in the storage case 9 and is vaporized.
Is sent to the compressor 10 stored therein, where the vaporized refrigerant is compressed to a high temperature and high pressure state.

The high-temperature and high-pressure vaporized refrigerant compressed and heated by the compressor 10 passes through the refrigerant flow path 8 contained in the connecting pipe 20 and the clothes-side heat contained in the clothes main body 1 having heat insulation and cooling properties. The refrigerant is sent to the exchanger 7, where the high-temperature and high-pressure vaporized refrigerant emits heat to the outside air and loses heat of evaporation to become a liquefied refrigerant.
The liquefied refrigerant liquefied by the outer heat exchanger 16 is supplied to an expansion valve 1 for separating a high pressure section and a low pressure section of a heating operation cycle.
The pressure is reduced and the temperature is lowered through the capillary tube 9 or the capillary tube and sent into the outer heat exchanger 16, and thereafter the heating operation is repeated in the same manner.

When the garment body 1 is used as a dehumidifying operation so as to bring the garment body 1 into a dehumidified state, it is operated in the same manner as in the cooling operation cycle, and water vapor such as sweat from the body in the garment body 1 is cooled by the cold garment side heat. What is necessary is just to condense and collect | recover by the exchanger 7. At this time, the power of the compressor 10 may be adjusted so as to absorb only latent heat as much as possible, and the air volume may be appropriately controlled.

Also, instead of using the garment body 1 in this embodiment as work clothes in a factory, the garment body 1 is cool in summer and warm in winter in offices and work places outdoors. It may be used as underwear or the like, or formed as an outerwear for work in a factory, a workplace in an office, or a workplace outdoors.
