Problems solved by technology

[0003] In the prior art, for the heating mode of the air conditioner, when the compressor is running, the indoor unit controls the operation of the fan of the indoor unit according to its coil temperature; When the set temperature is reached and the conditions for stopping the compressor are reached, although the compressor has stopped running at this time, there is still residual heat in the indoor coil, and the coil temperature is still high. The temperature of the indoor electric control board will rise, causing the temperature rise of the components, which will affect the service life of the components, and the system pressure will not reach the equilibrium state as soon as possible.

Embodiment Construction

[0021] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] In this example, if in the heating state, the air door blade position of the indoor unit when the compressor stops running is as follows: figure 1 As shown in position 3 in , at this time, the speed of the indoor unit fan is "high wind" wind speed (generally, the air volume of the indoor fan is divided into four wind speeds: high wind, medium wind, low wind, and light wind, but in practice it does not limited to these four wind speeds); the waste heat control method in this example is as follows figure 2 As shown, it includes the following steps:

[0023] 1. Keep the indoor unit fan running continuously to blow waste heat to the indoor unit coil to reduce the coil temperature and try to make the system pressure reach a balanced state;

[0024] 2. Sampling indoor unit coil temperature T, waste heat blowing time t (tim...

Abstract

The invention relates to an air conditioner control technology and discloses an air conditioner waste heat blowing control method. Waste heat of a coiler of an indoor unit is blown out as quickly as possible after a compressor halts, so as to reduce the temperature of the coiler, and system pressure is in a balanced state to the greatest extent. The air conditioner waste heat blowing control method comprises the steps that: a fan of the indoor unit continuously operates to blow waste heat of the coiler of the indoor unit after the compressor stops in a heating state, and the temperature or waste heat blowing time of the coiler of the indoor unit is acquired and compared and judged with a preset threshold value, so as to realize corresponding regulation on the rotating speed of the fan of the indoor unit. The air conditioner waste heat blowing control method provided by the invention is applicable to waste heat blowing on indoor coilers of various air conditioners.

Description

technical field [0001] The invention relates to the air conditioner control technology, in particular to a control method for blowing waste heat to the coil of the indoor unit to reduce the temperature of the coil after the compressor of the air conditioner is shut down. Background technique [0002] An air conditioner generally includes an indoor unit and an outdoor unit. The indoor unit is responsible for receiving the remote control signal or button signal of the remote control, and controls the corresponding actions of its actuators by decoding the signal (such as: the operation of the indoor unit fan, the temperature of the indoor unit coil, etc.) sampling, the position of damper blades, etc.), and pass the control command to the outdoor unit through handshake communication with the outdoor unit, and the outdoor unit controls the corresponding action of its actuator according to the corresponding control command (such as: compressor start / stop, outdoor unit fan operati...
