れ途中から再循環する。 In the above configuration, the case where various spaces or rooms are cooled will first be described. When the shaft 1 is rotated via a prime mover and a clutch (not shown), a rotor 2 for cooling fluid and a first rotor 4 and a second rotor 5 of a two-stage compressor 3 for refrigerant rotate integrally. For this reason, the air conditioning refrigerant (freon alone or a mixture) is first compressed in the first rotor 4, intermediately cooled in the first condenser 21 on the way from the inlet 33 to the outlet 22, and then Enters from the inlet 23 of the rotor 5, is recompressed internally, and exits 25
The oil is further cooled in the second condenser 24 and sent to the oil separator 26. Here, the oil component of the air conditioning refrigerant is separated, and this is returned to the inlet 33 of the first rotor 4 through the third valve 34. Furthermore, the air conditioning refrigerant passes through a liquid tank 27,
It is sent from the first valve 28 to the expansion valve 29, which opens when the temperature is high according to the action of the temperature sensor 29a, and is activated by an adsorbent material (for example, silica gel, activated carbon , zeolite, glass fiber filter, etc.) is raised to cool the room. If the room becomes too cool, the temperature sensor 29a operates and the expansion valve 29 closes. The air conditioning refrigerant that cools the room and makes it warm is the second one.
It is returned to the inlet 33 of the first rotor 4 through the valve 32 and recirculated together with the separated oil component. In addition, the still cold air conditioning refrigerant remaining after cooling the room is transferred from the second branch point 39 to the fifth valve 38.
The air is returned to the second inlet 49 of the second rotor 5 through the air and recirculated from the middle.

することも可能である。 Next, if you want to cool the inside of the freezer 80,
The air conditioning refrigerant cooled as described above may be allowed to flow from the air conditioning refrigerant circuit 20 to the freezer refrigerant circuit 50 by opening the sixth valve 51. This refrigerant is further sent to the second expansion valve 53, which is opened when the temperature is high according to the action of the temperature sensor 53a, thereby opening the inner tube of the cooler 54 shown in detail in FIGS. 2 and 3. 54a
and the outer tube 54b in order to cool the cooling plate 72, thereby cooling the inside of the freezer 80 (the regenerator 85 thereof). When there is no regenerator 85, it is also possible to fill it with water and make ice.

を通り長さが４〜５ｍとなり、約10℃の温度降下
が実験的に得られる。 Here, if the inside of the freezer 80 is cooled too much, the temperature sensor 53a works and the expansion valve 53
closes. The refrigerant that has cooled the inside of the freezer 80 and has become warm flows through the refrigerant flow path b of the outer pipe 54b, passes through the sixth branch point 59, the eighth valve 57, and then the fifth branch point of the air conditioning refrigerant circuit 20. 58 to the second inlet 49 of the second rotor 5, and is recirculated from the middle. At this time, the cooler 54 and the valve 51,
55 is made of a double tube (FIG. 5), and the inner tube 54a is made of metal, rubber containing metal wire, or plastic material, so that the same effect as that of a heat exchanger can be obtained. For example, fluid tank 27,
Since the sixth valve 51 is located, for example, in the engine compartment of a passenger car, the refrigerant is supplied to the sixth valve 51 in the summer.
1, the temperature is as high as 30 to 45°C, but at the inlet 92 of the expansion valve 53 in the trunk, the a of the double pipe is
The length is 4 to 5 m, and a temperature drop of about 10°C can be experimentally obtained.

Ｑ＝Ｍ・△Ｈであるから、
（H33−H28）Ｍ≫（H58−H28）Ｍ
となることより明らかである。 If you want to lower the freezing temperature on the freezer side without requiring too much air conditioning in the car, the refrigerant that has exited the cooler 31 in the air conditioning refrigerant circuit 20 is passed from the second branch point 39 to the fifth valve 38 and then to the fifth valve 38. 2. Return to the inlet 49 of the rotor 5. As a result, the first expansion valve 29 and the fifth
The expansion ratio with respect to the valve 38 is reduced, and the amount of refrigeration is reduced. That is, if the enthalpy at each pressure is H (the subscript numbers are the same as in Figure 1) and the flow rate of the refrigerant is M, then the amount of refrigeration Q is Q = M △H, so (H 33 - H 28 )M≫(H 58 −H 28 )M.
また前記冷凍庫８０の冷却が必要でない場合、
通常の空調となることは当然である。 Further, if cooling of the freezer 80 is not necessary,

From the condenser 24 (for condensing refrigerant) to the first condenser 21
, and then the radiator 62 at the front of the car.
is cooled down and returns to the suction port 63. In this system, the radiator 62 uses liquid and air, and the second condenser 24 uses liquid and two-phase flow (condensation process), so each has high heat transfer efficiency and can be made small and lightweight.

Control can be simplified. Furthermore, as shown in Fig. 1, when reducing the amount of refrigeration on the freezer 50 side and increasing the amount of air conditioning, open the eighth valve 57 and second valve 32 and close the seventh valve 55 and fifth valve 35. can. In these methods, when the expansion ratio is halved, the amount of refrigeration is also approximately halved.

In other words, the spring brings the regenerator and cooler of the portable freezer into good thermal contact by its spring force. Further, the bellows prevents the cooler from coming into direct contact with the outside air, thereby reducing heat intrusion loss from room temperature, and also provides a degree of freedom to the cooling plate to bring it into good thermal contact with the regenerator.
