Abstract

The invention discloses a control method of a wall-mounted type air conditioner. The control method comprises the steps that when a refrigeration energy-saving comfort instruction is received and the current indoor temperature is not smaller than an indoor environment temperature threshold value, the air conditioner runs according to an original frequency converting control mode; if not, the compressor target frequency calculated out according to the original frequency converting control mode is obtained, and whether the compressor target frequency is smaller than the first set compressor frequency or not is judged; if yes, a compressor is controlled to run according to the first set compressor frequency, and an outdoor fan is controlled to run at the set rotating speed; and if not, the compressor and the outdoor fan are controlled to run according to the original frequency converting mode. In the original frequency converting control mode, indoor temperature PID control or dual PID control comprising coil pipe temperature PID control is executed on the compressor, the coil pipe target temperature adopted in coil pipe PID control is determined according to the indoor real-time humidity, and compensation is carried out on the indoor temperature in indoor temperature PID control. By applying the control method, the energy saving and refrigeration comfort of the air conditioner are improved.

Description

technical field

[0001] The invention belongs to the technical field of air conditioning, and in particular relates to a control method for a wall-mounted air conditioner. Background technique

[0002] In the hot summer, the indoor air can be cooled by using the inverter air conditioner to create a cool environment for users. However, inverter air conditioners consume a lot of power and often become the main power-consuming appliances in the home.

[0003] In order to solve the uncomfortable problem caused by cold air blown out by refrigeration, the control method of controlling the operating frequency of the compressor can be based on the coil temperature of the indoor heat exchanger as the control target. In the existing coil temperature control process, the target temperature of the coil adopts a fixed value, which is generally a fixed temperature value solidified in the storage of the air conditioner. In the actual use process, there is often a phenomenon: in the case o...
