The invention discloses a refrigerating system and a control method of the refrigerating system. The refrigerating system is used for a vehicle and comprises a compressor, a condenser, a liquid storage tank, an evaporator, a first branch and a pressure release valve. One end of the condenser is communicated with an exhaust port of the compressor; the other end of the condenser communicates with the inner space of the liquid storage tank, a heat exchange pipe is arranged in the liquid storage tank, and one end of the heat exchange pipe communicates with an air return opening of the compressor. One end of the evaporator is communicated with the internal space of the liquid storage tank, and the other end is communicated with the other end of the heat exchange tube; the first branch is connected with an exhaust port of the compressor and one end, deviating from an air return port of the compressor, of the heat exchange tube; and the pressure release valve is arranged on the first branch. According to the refrigerating system, when the pressure of the refrigerant flowing out of the exhaust port of the compressor is too large, the pressure values of the exhaust port and the air inlet of the compressor can be adjusted, the situation that the compressor is in an overload state for a long time is avoided, refrigerating system faults are avoided, and refrigerating failure of a vehicle is avoided.

    本发明公开了一种制冷系统和制冷系统的控制方法,制冷系统用于车辆且包括压缩机、冷凝器、储液罐、蒸发器、第一支路和泄压阀。冷凝器的一端与压缩机的排气口连通;冷凝器的另一端与储液罐的内部空间连通,储液罐内具有换热管,换热管的一端与压缩机的回气口连通;蒸发器的一端与储液罐的内部空间连通,另一端与换热管的另一端连通;第一支路连接压缩机的排气口和换热管的背离压缩机回气口的一端;泄压阀设于第一支路上。根据本发明的制冷系统,在压缩机排气口流出的冷媒的压力过大时,可以调节压缩机的排气口和进气口处的压力值,避免压缩机长时间处于超负载状态,避免引起制冷系统故障,避免造成车辆的制冷失效。
