Dust accumulation determining method and device for air conditioning equipment

Abstract

The embodiment of the invention provides a dust accumulation determining method and device for air conditioning equipment, and relates to the field of air conditioning equipment. According to the dustaccumulation determining method and device for the air conditioning equipment, a theoretical temperature value between an air inlet and an air outlet is calculated according to a second actual temperature value, a third actual temperature value, the first heat exchange coefficient and the first contact area of the contact face between a preset heat transfer medium layer and the air outlet of theair conditioning equipment, and the second heat exchange coefficient and the second contact area of the contact face between the preset heat transfer medium layer and the air outlet of the air conditioning equipment; and when the difference value between the theoretical temperature value and a first actual temperature value is beyond the preset range, dust accumulation of the air conditioning equipment is determined, thus manual monitoring is not needed, convenience is well achieved, accumulated dust of the air conditioning equipment is cleared in real time, and the overall use effect of the air conditioning equipment is not affected accordingly.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to a method and device for determining dust accumulation in air-conditioning equipment. Background technique [0002] After the room air conditioner (that is, the air conditioner itself or the outdoor unit of the air conditioner) has been used for a period of time, due to the presence of dust in the air, the internal parts of the indoor unit (such as filters, heat exchangers, and air ducts) cannot avoid dust accumulation. After the dust accumulates, the air volume of the indoor unit becomes smaller, the use effect, energy efficiency ratio, and reliability all decrease to varying degrees, and bacteria are easy to breed. Therefore, the air conditioner needs to be cleaned after a period of use. However, the indoor unit of the wall-mounted air conditioner is installed under the ceiling at a high position, and it is difficult for users to observe the dust accumulation....

AI Technical Summary

Problems solved by technology

After the dust accumulates, the air volume of the indoor unit will decrease, the use effect, energy efficiency ratio, and reliability will all decrease to varying degrees, and bacteria will easily breed. Therefore, the air conditioner needs to be cleaned after a period of use

However, the indoor unit of the wall-mounted air conditioner is installed under the ceiling at a high position, and it is difficult for users to observe the dust accumulation. Therefore, most users do not take the initiative to clean it, and often wait for the use effect of the air conditioner to drop significantly before checking.

[0003] At present, most air conditioners on the market have a cleaning function, but users cannot manually or automatically clean the dust accumulated in the air conditioner in real time when the air conditioner accumulates dust, which will lead to a decrease in the air volume of the indoor unit and lower the use effect and energy efficiency ratio. , Reliability declines to varying degrees, and manual monitoring is required, which is very inconvenient
