Problems solved by technology
[0003] But for fixed-speed household air conditioners, it cannot be adjusted in real time according to the change of room heat load like the inverter machine.
In this way, the energy can only be adjusted by frequent start and stop, which not only does not save energy but also affects the life of the press

The invention discloses a non-stop control method of a constant-frequency air conditioner. The non-stop control method of the constant-frequency air conditioner comprises the steps of detecting an outdoor environment temperature; when the outdoor environment temperature is in a preset temperature range, adjusting the running quantities of indoor heat exchangers and outdoor heat exchangers and the running quantities of indoor fans and outdoor fans according to the temperature interval range in which the outdoor environment temperature is located; when the outdoor environment temperature is outside the preset temperature range, detecting temperature deviation between the indoor environment temperature and a set temperature; and adjusting the running quantities of the indoor heat exchangers and the outdoor heat exchangers and the running quantities of the indoor fans and the outdoor fans according to the temperature deviation. According to the non-stop control method of the constant-frequency air conditioner, the heat load of a room can be matched with energy output of the constant-frequency air conditioner without shutdown, the working performance of the air conditioner is improved and the influence on the service life of a compressor can be avoided.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a non-stop control method for a fixed-frequency air conditioner. Background technique [0002] At present, most of the air conditioners are traditionally set to operate in cooling mode in high temperature environment and in heating mode in low temperature environment, but for some special needs, the air conditioner needs to operate in cooling mode in low temperature condition. However, when the air conditioner is running in the low-temperature refrigeration mode and the operating load is small, the exhaust pressure of the compressor will be too small, resulting in insufficient pressure ratio of the compressor. If it is operated for a long time, the compressor may lack oil and affect the air conditioner. The stability of the system operation. For variable frequency compressors, the frequency of the compressor can be adjusted to adapt the compressor to the heat load of th...
