Problems solved by technology

[0002] Inverter air conditioners and other refrigeration equipment include electronic control components. When they are used under high frequency conditions such as cooling overload, they are often shut down due to the high temperature of key components in the electronic control components, which greatly limits the maximum operating frequency of the compressor. , thus limiting the capacity output of the air conditioner
[0003] In related technologies, a refrigerant radiator is used to dissipate heat from the electric control, but the conventional air-conditioning system of a compressor without an air supplement function arranges the refrigerant radiator between the condenser outlet and the throttle valve, and the cooling effect is limited.

Abstract

The invention provides a refrigerant system and refrigeration equipment. The refrigerant system comprises: a compressor, wherein the compressor comprises an air suction port, an air supply port and an exhaust port; a first heat exchanger, wherein one end of the first heat exchanger is communicated with the exhaust port; an air supply device which is communicated with the other end of the first heat exchanger and an air supply port of the compressor; a second heat exchanger which is communicated with an air suction port of the compressor and the air supply device; a first throttling element which is arranged between the first heat exchanger and the air supply device; a second throttling element which is arranged between the air supply device and the second heat exchanger; and a refrigerant radiator which communicates with the air supply device, wherein the refrigerant radiator is located between the air supply device and the air supply port or located between the first throttling element and the air supply device. A medium-temperature medium-pressure refrigerant flow path is used for cooling an electric control component, so that the temperature of the electric control component is reduced, the operation frequency of the compressor can be improved, and the output capacity of the refrigerant system is improved.
