Problems solved by technology

Therefore, the pressure loss between the evaporator 5 and the compressor 1 is large, and there is not enough cooling capacity
The first liquid reservoir 6, the second liquid reservoir 7 and the connecting pipe 8 take up a relatively large space, and also need a longer connecting pipe 8 and two pressure vessels, so the production cost is higher
In addition, there will be a large number of solder points, which will reduce the reliability
