Problems solved by technology
[0002] At present, in the traditional air-conditioning system, the heat dissipation of the electronically controlled inverter module is mainly through the convective heat exchange of the air, but because the air temperature is low in winter and high in summer, the cooling effect of the inverter module is not good when the ambient temperature is high in summer, and the air conditioner The system cannot achieve the best performance, and long-term high-temperature operation may easily cause system protection or damage to the inverter module, which will affect the reliability of the system operation

The invention provides an air-conditioner outdoor unit and an air conditioner. A radiator of the air-conditioner outdoor unit is installed on an inverter module, an oil separator is connected with the radiator through a second pipeline, a gas-liquid separator is communicated with the radiator through a pipeline, and an electronic expansion valve is located at the position of a liquid outlet of the gas-liquid separator. A temperature control device detects temperature of the inverter module and refrigerant oil flowing from the oil separator and controls the opening or closing of the electronic expansion valve and / or controls connection or closure of the second pipeline according to the detected temperature. The inverter module can be cooled by temperature difference of the refrigerant oil and the inverter module of the air-conditioner outdoor unit, the temperature control device controls the electronic expansion valve to open when the inverter module cannot be effectively cooled through the refrigerant oil; the inverter module can be cooled through low-temperature refrigerant and the refrigerant oil in the gas-liquid separator, so that cooling effect and system reliability of the inverter module are guaranteed, and system performance is improved.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an outdoor unit of an air conditioner and an air conditioner including the outdoor unit of the air conditioner. Background technique [0002] At present, in the traditional air-conditioning system, the heat dissipation of the electronically controlled inverter module is mainly through the convective heat exchange of the air, but because the air temperature is low in winter and high in summer, the cooling effect of the inverter module is not good when the ambient temperature is high in summer, and the air conditioner The system cannot achieve the best performance, and long-term high-temperature operation may easily cause system protection or damage to the inverter module, which will affect the reliability of the system operation. Contents of the invention [0003] In order to solve at least one of the above-mentioned technical problems, an object of the present inventio...
