Embodiment 1

[0031] This embodiment provides a control method for air conditioning and heating modes, such as figure 1 As shown, the control method of the heating mode of the air conditioner includes the following steps, S1: in the heating mode, detect the outdoor ambient temperature Ts; S2: record each switching time of the electric auxiliary heating, and calculate according to the switching time of the electric auxiliary heating The switching times Ns of the electric auxiliary heating within a preset time; S3: Control the operating frequency of the compressor and the on-state of the electric auxiliary heating according to the outdoor ambient temperature Ts and the switching times Ns of the electric auxiliary heating.

[0032] Specifically, combined with figure 2 As shown, when the air conditioner is in the heating mode, it detects the outdoor ambient temperature Ts, and when the outdoor ambient temperature Ts is at or above the first preset temperature value T1, the air conditioner ente...

Embodiment 2

[0043] This embodiment is on the basis of above-mentioned embodiment 1, combines image 3 As shown, when the air conditioner is in the heating mode, it detects the outdoor ambient temperature Ts, and when the outdoor ambient temperature Ts is at or above the first preset temperature value T1, the air conditioner enters the normal auxiliary heating mode, and there is no need to turn on the electric auxiliary heating at this time , the heat demand can be met only by the operation of the compressor. Therefore, in the conventional auxiliary heating mode, the electric auxiliary heating is turned off first, and the compressor is used for heating; when the outdoor ambient temperature Ts is below the first preset temperature value T1, only by The compressor cannot obtain sufficient heat supply for heating. At this time, it is necessary to turn on the electric auxiliary heating to meet the heat demand. When the electric auxiliary heating is turned on, due to excess heat, the electric au...

Embodiment 3

[0048] This embodiment is on the basis of above-mentioned embodiment 2, combines Figure 4 As shown, when the air conditioner is in the heating mode, it detects the outdoor ambient temperature Ts, and when the outdoor ambient temperature Ts is at or above the first preset temperature value T1, the air conditioner enters the normal auxiliary heating mode, and there is no need to turn on the electric auxiliary heating at this time , the heat demand can be met only by the operation of the compressor. Therefore, in the conventional auxiliary heating mode, the electric auxiliary heating is turned off first, and the compressor is used for heating; when the outdoor ambient temperature Ts is below the first preset temperature value T1, only by The compressor cannot obtain sufficient heat supply for heating. At this time, it is necessary to turn on the electric auxiliary heating to meet the heat demand. When the electric auxiliary heating is turned on, due to excess heat, the electric a...

Abstract

The invention discloses a control method of the air-conditioner heating mode, a control device and an air-conditioner and relates to the technical field of air-conditioner control. The control methodof the air-conditioner heating mode comprises the steps that under the heating mode, each-time on-off time of an electric auxiliary heater is recorded, and the number of on-off times Ns of the electric auxiliary heater within preset time is calculated according to the on-off time of the electric auxiliary heater; and according to the number of on-off times of the electric auxiliary heater, the working frequency of a compressor and the starting state of the electric auxiliary heater are controlled. The control device of the air-conditioner heating mode comprises a sensor and a controller. According to the control method of the air-conditioner heating mode, the control device and the air-conditioner, the problem that due to frequent starting of an existing electric auxiliary heater, the indoor temperature fluctuates greatly is solved, meanwhile, the problems that due to frequent starting of the electric auxiliary heater, the life loss of the electric auxiliary heater and a relay device is caused can be solved, and durability of the electric auxiliary heater and the corresponding relay device is effectively improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning control, in particular to a control method, a control device and an air conditioner for the heating mode of an air conditioner. Background technique [0002] In the existing air conditioning field, in order to improve the heating capacity at low temperatures, the air conditioner uses electric auxiliary heating to assist heating to ensure the stability of the room temperature and bring users a comfortable experience. [0003] In the prior art, the control method of the electric auxiliary heating is: when the air conditioner is close to the set temperature, the electric auxiliary heating is turned off preferentially. When the external ambient temperature is high, the operating frequency of the compressor can be increased to meet the heating requirements. When the external ambient temperature is low, even if the operating frequency of the compressor is increased, the overall heating effect o...
