Embodiment Construction
[0017] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0018] Such as figure 1 As shown, the air conditioning unit according to the present invention includes: a frequency converter 10; an independent cooling system 20 for cooling and heat dissipation of the frequency converter 10; a unit control device 30 for detecting the working state of the frequency converter 10; State, to control the independent cooling system 20 to start or stop. That is, the present invention sets the independent cooling system 20 and controls the independent cooling system 20 to start or stop according to the working state of the frequency converter 10 . That is to say, when the frequency converter 10 is working, the independent cooling system 20 is turned on, and when the frequency converter 10 is not working, the independent cooling system 20 is stopped, which solves the problem in the prior art that the cooling of the frequency co...

The invention discloses an air conditioning unit and a control method. The air conditioning unit disclosed by the invention comprises a frequency converter, an independent cooling system, and a unit control device, wherein the independent cooling system is used for cooling and heat dissipation of the frequency converter; and the unit control device is used for detecting the working state of the frequency converter, and controlling the independent cooling system to start or halt according to the working state of the frequency converter. According to the air conditioning unit and the control method, the independent cooling system is provided and is controlled to start and halt according to the working state of the frequency converter, namely if the frequency converter works, the independent cooling system is started, and if the frequency converter does not work, the independent cooling system is halted, so that the problem that the cooling of the frequency converter can be realized only through a refrigerating circulating system in the prior art is solved and the problem of the air conditioning unit that the frequency converter cannot be cooled when the refrigerating circuiting system does not run is solved.
Description
technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner unit and a control method. Background technique [0002] In the prior art, the cooling of the frequency converter of the air-conditioning unit generally relies on the refrigeration cycle system of the unit. For example, the power electronic device for cooling the frequency converter is installed in a heat conduction relationship with a heat sink, and is transferred from the refrigeration cycle system through the circulation pipeline. The refrigerant output from the condenser is sent to the radiator, so that the refrigerant and the radiator have a heat conduction relationship, and a control valve is set on the circulation pipeline to adjust the refrigerant flow through the pipeline to keep the temperature of the radiator at the required level. within range. [0003] However, the way of cooling the inverter in the prior art can only cool the inverter when the ref...
