Embodiment 1

[0078] image 3 It is a flow chart of a specific embodiment of the control method for slowing down the defrosting decay of the air conditioner in the present invention. Among them, the value of the outdoor coil temperature sensor is T1, the value of the outdoor ambient temperature sensor is T2, the value of the indoor coil temperature sensor is T3, the set value of the outdoor fan speed is R, and the set value of the compressor operating frequency is H. The frost temperature difference is Tdil, and the temperature change rate of the outer disk is ΔT. Such as image 3 As shown, the control method includes:

[0079] S0, after the air conditioner unit is turned on and runs stably for 10 minutes, detect the value T1 of the outdoor coil sensor;

[0080] S1, when the outdoor coil temperature T1 ≤ A is detected, the first action is started. First, the current compressor operating frequency setting value H is reduced by the predetermined frequency correction value B1, that is, the ...

Abstract

The invention provides a control method for slowing down air conditioner defrosting attenuation. The control method comprises the steps: S0, the air conditioner enters a heating mode; S1, the operation frequency of an air conditioner compressor is controlled according to the outdoor coil pipe temperature and the change rate thereof; S2, the rotating speed of an outdoor fan of the air conditioner is controlled according to the difference value between the outdoor environment temperature and the outdoor coil pipe temperature; and S3, whether a defrosting mode is started or not is determined according to the indoor coil pipe temperature. Therefore, under the condition that the cost of the air conditioner is not increased, the frequency of the compressor and the rotating speed of the outdoor fan are set to control defrosting and slow down heating attenuation of the air conditioner through the temperature change rate of the outdoor coil pipe, the difference value between the outdoor environment temperature and the outdoor coil pipe temperature, meanwhile, the air outlet temperature is ensured not to be too low, and the somatosensory comfort is improved.

Description

technical field [0001] The present invention and the technical field of air conditioning, in particular, relate to a control method for slowing down defrosting decay of an air conditioner and an air conditioner. Background technique [0002] When the air conditioner is in heating operation in winter, the outdoor heat exchanger exchanges heat with the external environment. It absorbs the heat from the outdoor environment and transfers it to the room. When the surface temperature of the outdoor heat exchanger is lower than the air dew point temperature, the outdoor heat exchanger will condense Frost will affect the heating effect. However, the conventional defrosting method often has the problem of excessive attenuation of the heating capacity of the air conditioner, which affects the user experience of the air conditioner. Contents of the invention [0003] The problem solved by the invention is to slow down the attenuation during the defrosting process of the air conditio...
