Pneumatic gas wave refrigerator

Abstract

The invention discloses a pneumatic gas wave refrigerator, which comprises a machine body and a rotary distributor arranged in the machine body in a sealing way. A cooling air collection part is arranged in an inner cavity of the machine body. The inner cavity is provided with oscillator tubes in a communication way. A hollow main shaft of the rotary distributor is communicated with the oscillator tubes. The open end of the hollow main shaft is in sealing connection with gas tubes respectively. At least two paths of high pressure gases are introduced into the oscillator tubes by the gas tubesto form high temperature refrigeration loop respectively. Impellers are arranged on the hollow main shaft of the rotary distributor. The sidewall of the machine body is provided with a gas driving inlet and a gas driving outlet in a through way respectively. At least one path of high pressure gas is introduced into the cooling air collection part from the gas driving inlet to drive the rotation of the impellers to form a high pressure speed regulation loop. The pneumatic gas wave refrigerator of the embodiment of the invention can remarkably improve the refrigeration efficiency, still can actively regulate a rotating speed under the condition of no motor, has a compact structure, and is convenient to operate and easy to control.

Description

technical field [0001] The invention relates to a refrigeration machine, in particular to a pneumatic air wave refrigerator. Background technique [0002] Existing low-temperature refrigeration technology mostly uses multi-stage compressed refrigerants to achieve low temperature. The first stage compresses a refrigerant, and the second stage compresses the second refrigerant on the basis of absorbing the cooling capacity obtained by the first stage compression, and achieves the purpose of cooling through the vaporization and heat absorption of the refrigerant, usually the second stage compression The temperature of the refrigerant liquidation point used is lower than the liquidation point temperature of the first-stage refrigerant. There are many disadvantages in using this refrigeration method: firstly, due to the multi-stage compression, the refrigeration efficiency is low; secondly, due to the use of refrigerant, it is not conducive to environmental protection; Security...

There are many disadvantages in using this refrigeration method: firstly, due to the multi-stage compression, the refrigeration efficiency is low; secondly, due to the use of refrigerant, it is not conducive to environmental protection; Security risks

Even so, gas leakage is still unavoidable, and the cost of monitoring and processing this part of the leaked gas is very high, and there are certain requirements for the purity of the gas source entering the gas wave refrigerator; Due to the inability to actively adjust the rotation speed, the refrigeration efficiency of the air wave refrigerator is relatively low
