Do you really know how to maintain the central air conditioner in winter?

The weather is getting colder and colder, the central air conditioner is used~

But before using central air-conditioning for heating in winter, we must do its maintenance work. How to maintain the central air conditioner in winter? The following air conditioner maintenance manufacturers will teach you:

Maintenance step: add lubricating oil.

In the long autumn, most of the central air conditioners are not used. If the central air conditioners do not operate for a long time, the lubricating oil in the compressor may condense together and lose its lubricating effect, which will affect the normal operation of the compressor. If the lubricating oil in the compressor is condensed, we must promptly dispose of it and replace it with a new lubricating fluid.

The second step of maintenance: clean regularly.

After three or four months of non-use in the autumn, a large amount of dust will be deposited on the outside of the central air-conditioning main machine and the internal parts of the machine. How can it not be cleaned and treated in time, it will inevitably affect the efficiency of the central air-conditioning heating and cooling, simple The method is that we can clean the condenser, the main body shell, and the filter screen with water and some cleaning agent.

Three steps of maintenance: proper temperature control.

For the use of central air-conditioning in winter, setting the temperature of central air-conditioning is also a science, we can set it to 22℃,

First, this temperature is a comfortable temperature environment for people,

Second, how to maintain the central air conditioner is particularly beneficial. A moderate temperature can reduce the damage to the compressor, reduce power consumption and extend the service life of the central air conditioner.

The above is the method of central air conditioning maintenance in winter that the Shanghai Central Air Conditioning Project will tell you. The central air conditioner must be cleaned and maintained before and after use.
