Abstract

The invention relates to the field of air conditioner control and especially relates to a regulating system for a fixed frequency machine, a regulating method thereof and a fixed frequency air conditioner. In the regulating system, a compressor, an indoor side evaporator and an outdoor side condenser are formed into a circulation loop; a flow regulating structure is arranged on a pipeline between the indoor side evaporator and the outdoor side condenser; a temperature measuring structure is arranged at an air inlet of the indoor side evaporator; a low-pressure air inlet of the compressor is connected with the pipeline between the flow regulating structure and the outdoor side condenser through a first return pipe; and a control valve is arranged on the first return pipe. The opening degree of the flow regulating structure is controlled according to the temperature at the air inlet of the indoor side evaporator and a comparison result between the temperature and a preset temperature, so that the refrigerant flow between the indoor side evaporator and the outdoor side condenser can be adjusted, the heat exchange volume of the indoor side evaporator can be regulated, and the indoor temperature can be regulated. The regulation has little influence on the indoor temperature, and the startup and shutdown are not required in a regulation process, so that no higher noise is generated, and the service life of the compressor is prolonged.

Description

technical field [0001] The invention relates to the field of air-conditioning control, in particular to a fixed-frequency machine adjusting system, an adjusting method thereof, and a fixed-frequency air conditioner. Background technique [0002] At present, in the process of adjusting the capacity of the fixed frequency air conditioning unit, when the temperature reaches the set temperature, it may be downshifted or directly shut down when the temperature reaches the set temperature. However, since the speed of the fixed-frequency compressor cannot be adjusted, the above method will cause frequent switching. Frequent switching of gears will cause excessive noise indoors, which will give users a bad feeling and cause complaints. [0003] However, there are still many fixed-frequency machines with a single gear, which cannot be adjusted by switching gears during adjustment, but can only be adjusted by adjusting the throttling device, resulting in frequent shutdowns due to hig...
