The outfan of switching device 2 connects the input of compressor 1；
Cold-producing medium inputs from compressor 1 to switching device 2 direction and is exported to compressor 1 direction from switching device 2.
As shown in Fig. 2 wherein switching device 2 is made up of switching valve 11 and three pipelines, by switching valve 11 internal valves
Can achieve that the first pipeline 4 and second pipe 5 communicate, or the first pipeline 4 and the 3rd pipeline 6 communicate.By the 3rd pipeline 6 and refrigeration
Agent input direction connects；Second pipe 5 is connected with pressure gauge 3, and the first pipeline 4 is connected with cold-producing medium outbound course.
Preferably, as shown in figure 3, pressure gauge 3 includes display screen 10, pressure detection circuit 7, design of pressure circuit 8 and
Comparison circuit 9；
