Embodiment Construction

[0030] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] The core idea of ​​the present invention is: based on the sensitivity of the human body to the range of indoor temperature fluctuations, by changing the existing conditions for starting defrosting, and then properly raising the indoor temperature at an appropriate time, the defrosting process will be performed to reduce the User discomfort caused by large fluctuations in indoor temperature.

[0032] refer to figure 1 , figure 1 It is a schematic flowchart of an embodiment of the defrosting control method for the air conditioner of the present invention. In this embodiment, the defrosting control method includes:

[0033] Step S10, monitoring whether the air conditioner currently reaches the preset defrosting condition;

[0034] In this embodiment, the air conditioner needs to monitor and judge defrosting co...

Abstract

The invention discloses a defrosting control method of an air conditioner, comprising: monitoring if the air conditioner achieves a preset defrosting condition at present; increasing the present heating output of the air conditioner to raise the indoor temperature when the air conditioner achieves the present defrosting condition at present; monitoring if a difference value between the present indoor temperature and the set air conditioner temperature is higher than the preset temperature, and monitoring if the air conditioner continuously operates to reach the preset operation time; and performing the defrosting when the difference value between the present indoor temperature and the set air conditioner temperature is higher than the preset temperature and / or the air conditioner continuously operates to reach the preset operation time. The invention further discloses a defrosting control device of the air conditioner and the air conditioner. The method monitors the defrosting condition formation time of the air conditioner beforehand to reduce the indoor temperature fluctuation amplitude caused by the defrosting so as to improve the user comfort through raising the indoor temperature.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a defrosting control method and device for an air conditioner and an air conditioner with the device. Background technique [0002] When using the air conditioner for heating in winter, in the heating mode of the air conditioner, when the temperature of the outdoor unit of the air conditioner is low, the water vapor in the outside air will frost on the fins of the outdoor unit heat exchanger, thus lead to poor heat transfer performance. In order to ensure the continuous heating of the air conditioning system, defrosting treatment is required. [0003] Generally, when defrosting, the air conditioning system switches the current heating mode to cooling mode to exchange the functions of the internal and external units of the air conditioner, so that the refrigerant in the external unit becomes high-temperature and high-pressure Freon, so that defrosting can be achieved. Since the c...
