When two heat exchangers are selected by the switch structure to form one working system and the saturation temperature corresponding to the internal pressure of the unselected heat exchanger is higher than the medium or environment temperature of the heat exchanger, a liquid refrigerant accumulates inside the non-working heat exchanger. According to the refrigeration system, the switch structure is arranged at either end of the non-working heat exchanger, so that the non-working heat exchanger is isolated from a working system cycle, and under the condition where the pressure at a low-pressure side (C; Q) of the working system is less than the internal pressure of the non-working heat exchanger, additional discharging channels (123, 124; 623, 624) communicate with the non-working heat exchanger and the low-pressure side (C; Q) of the working system, so that the refrigerant accumulating in the non-working heat exchanger is transferred to the system cycle, avoiding a lack of refrigerant in the system cycle.
