When the temperature difference reduce direction is in N1 < Ti-To < N2 time, device works on pattern 2 times, and N1 is that heat pipe major loop opens the critical lower limit temperature difference being used alone machine low-temperature receiver and running, and N2 >=N1;
As temperature difference Ti-To < N1, the work of heat pipe cooling major loop, opens the mode of operation 3 that mechanical refrigeration subloop runs simultaneously; Now main triple valve input is output with the second exchanger heat pipe end input and is communicated with, and secondary triple valve input is connected with the second heat exchanger air conditioner end input; Second heat exchanger work in heat pipe cooling major loop, heat pipe condenser do not work; The work of mechanical refrigeration subloop second heat exchanger, First Heat Exchanger do not work; Heat pipe major loop utilizes the cooling of the second heat exchanger and works, and making heat pipe major loop be used alone machine low-temperature receiver is room temperature lowering;
When the temperature difference is from Ti-To < N1 situation, change on temperature difference augment direction and be in N1 < Ti-To < N2 time unit work under mode 3; The temperature difference continues toward augment direction development again, and as temperature difference N2 < Ti-To < M1, unit is transformed into pattern 2 times.
