  Furthermore, the dimension of each part of the collecting pipes 24 and 25 and the dimension of each part of the relay pipe 23 are shown below.

It goes without saying that the dimensions shown above are values that are appropriately changed depending on the cooling capacity and heating capacity of the cooling and heating system. Furthermore, the air conditioning system according to the present embodiment includes a heat radiation short pipe 30. The heat radiation short pipe 30 can be constituted by a mini-cooler having a capacity of about 1/20 of the capacity of a normally used capacitor. Further, the heat radiation short pipe 30 can be used only during the cooling operation. The heat dissipation short pipe 30 is provided to dissipate the compression heat of the compressor 10. Accordingly, the heat radiation short pipe 30 can be provided as a predetermined length of the pipe 30A at the same position as the heat exchanger 50 as shown in FIG. 1, and the predetermined length of the pipe can be cooled by the fan of the heat exchanger 50. . The predetermined length in this case is that if the length of the pipe constituting the heat exchanger 50 is 1, when using the same diameter pipe, a 1/20 length pipe is provided and the heat radiation short pipe 30 is Can be configured.

Further, the air conditioning system according to the present embodiment is provided with a switching valve 40. The switching valve 40 is provided on the path of the heat medium between the heat radiation short pipe 30 and the heat exchanger 50, and either the first speed-heat converter 20A or the second speed-heat converter 20B. This is for switching connection. In this embodiment, the heat dissipation short pipe 30 is connected to the first speed-heat converter 20A or the heat dissipation short pipe 30 is connected to the second speed-heat converter 20B. ing.

A heat exchanger 50 is provided between the first speed-heat converter 20 </ b> A and the second speed-heat converter 20 </ b> B and the compressor 10. The heat exchanger 50 radiates heat to the outside air, for example, and is cooled by a fan. The compressor 10 and the heat radiation short pipe 30 are connected by a pipe 11, and the heat radiation short pipe 30 and the switching valve 40 are connected by a pipe 31.

The switching valve 40 and the first speed-heat converter 20A are connected by a pipe 41, and the switching valve 40 and the second speed-heat converter 20B are connected by a pipe 42. Yes. Further, a pipe 28 is connected to the spiral capillary 21 side of the first speed-heat converter 20A, and a pipe 26 is connected to the spiral capillary 21 side of the second speed-heat converter 20B. The pipe 28 and the pipe 26 are connected to the pipe 51 at the connection point 27. This pipe 51 is connected to the heat exchanger 50. The heat exchanger 50 and the compressor 10 are connected by a pipe 52. The thickness of each pipe may be larger than the diameter of the spiral thick tube 22 of the first speed-heat converter 20A, for example, the inner diameter of the spiral thick tube 22 of the first speed-heat converter 20A. It may be about 3 times.

In the spiral thin tube 21 and the spiral thick tube 22 of the first speed-heat converter 20A and the second speed-heat converter 20B, for example, a piano wire is inserted into a copper tube, and the copper tube is used as a piano. In order to form a tube by narrowing to the outer diameter (thickness) of the wire, a groove 60 as shown in FIG. 3 is formed on the inner wall. The groove 60 can be formed to advance while turning counterclockwise from the spiral thick tube 22 side toward the spiral thin tube 21 side.

Then, the spiral tube 21 and the spiral tube 22 are formed by twisting from the straight tube state to the spiral tube . At this time, since the outer side of the spiral tube is pulled in the length direction as a whole, the interval between the groove 60 and the adjacent groove 60 is wider than that in the straight tube state as shown in FIG.

On the other hand, when the spiral thin tube 21 and the spiral thick tube 22 are formed by twisting from the straight tube state to the spiral tube , the inside of the spiral tube is processed so as to be contracted in the length direction as a whole. Therefore, the interval between the groove 60 and the adjacent groove 60 is narrower than that in the straight pipe state as shown in FIG.

The gap between the grooves is different between the outside and the inside. Further, as described in Patent Document 1, spin vibration rotation occurs in the heat medium due to the constriction that occurs when the copper tube is twisted in the axial direction. It is considered that this has a particularly favorable influence on the heat conversion in the speed-heat converter.

During cooling, the switching valve 40 is operated so that the heat medium flows only to the second speed-heat converter 20B, and the first speed-heat converter 20A is not used.

The conditions of the compressor 10, the heat exchanger 50, the spiral thin tube 21, and the spiral thick tube 22 during heating and cooling are shown below. Figures in parentheses are numerical ranges.

Under the above conditions, at the time of heating, the heat medium is changed to a high-pressure high-temperature gas in the compressor 10 and is radiated by the heat exchanger 50 to become a room temperature liquid. Next, the process proceeds to the first speed-heat converter 20 </ b> A, and the heat medium is gasified and returned to the compressor 10 through the heat radiation short pipe 30 by decompression expansion due to energy emission by spin vibration rotation .

Further, at the time of cooling, the heat medium is compressed into a high-temperature gas in the compressor 10, and the heat of the compressor 10 is radiated through the heat radiation short pipe 30 to obtain a heat medium. Next, the heat medium is sent to the second speed-heat converter 20B, decompressed and expanded by spin vibration rotation, lowered in temperature while being liquid, sent to the heat exchanger 50, and heat exchanged to make all the gas. Return to the compressor 10.

The operation state in which the air conditioning system according to the present embodiment having the above configuration is applied to an automotive air conditioning system using Freon R134a is as follows. The rated cooling speed of the compressor, 940 rpm, high pressure 10 kg (about 10 to 12 kg), and low pressure 2.0 kg (about 2.0 to 2.5 kg) in the automotive cooling system, the cooling temperature was satisfactory when this embodiment was applied. . In the case of the heating cycle, since it is for automobiles, there is no conventional example to be compared. Hot air of 54 ° C was obtained from the outlet at a rated compressor speed of around 940 rpm (about 10 kg). That is, in the present embodiment, a sufficient cooling / heating effect can be obtained with a motor of about 5A in the present embodiment with respect to a motor with a rating of 24 to 30A, and power consumption can be reduced by about 80%. That is, it is expected that a sufficient heating effect and a sufficient cooling effect are exhibited while greatly reducing the power consumption.

The compressor pressure can be reduced by 20% to 40%, and the amount of power used can be reduced by 60 to 80% during heating and by a maximum of 60 to 80% even during cooling. In the present embodiment, the inner diameter of the spiral tubule and the spiral tubule is 1.8 to 4.0 mm, and the spiral groove on the inner wall of the spiral tubule and the spiral tubule has been described with reference to FIGS. By being formed in this way, the greatest feature is that spin vibration is applied to the heat medium and kinetic energy radiation is continuously generated.
