Points to know about maintaining household central air conditioners in winter

In winter, the central air-conditioning provides a warm and comfortable living environment for the family, and of course maintenance is indispensable. Shanghai Central Air-Conditioning Engineering Company tells you that doing the maintenance of central air-conditioning can not only extend the service life of the unit, but also save energy.

So, how to maintain household central air conditioners in winter?

Clean regularly

After three or four months of disabling the central air conditioner in autumn, there may be dust deposited on parts and components. In addition, if you have not used it for a long time, you need to clean it once before starting the machine. Use a vacuum cleaner to suck up the dust on it, or you can rinse it with clean water. When cleaning, pull out the filter, dry it, and put it in an air conditioner for use. For dusty environments, the filter should be cleaned frequently to prevent the air outlet from being blocked by dust.

Do not turn off and on again frequently

Many people are accustomed to turning it on for a while, turning off the air conditioner when the room is warm, and turning it back on after the temperature drops. This has achieved the goal of "saving electricity". It seems to save power, but frequent switching on and off of the air conditioner will cause more loss and damage the compressor.

Check the line on time

Winter is the peak period of electricity consumption, and people spend more time indoors, so the safety of electricity consumption needs to be paid attention to. Before use, always check whether the electrical plug of the air conditioner is in good contact with the socket. If you find that the power lead or plug is hot when the air conditioner is running, it may be caused by too thin electrical wiring or poor contact between the plug and the socket. Take corresponding measures to resolve the situation.

Proper temperature control

When using central air-conditioning in winter, the temperature can be set to about 25℃, which is a comfortable temperature for the human body surface. Moreover, the moderate temperature can reduce power consumption, thereby prolonging the service life of the central air conditioner.

Avoid blowing air directly on the body

Do not use the air conditioner to blow directly on the body in winter. Direct blowing will cause the local temperature of the human body to be too high, and the skin will automatically adjust the temperature. For example, it will adjust the body temperature by opening the sweat pores according to the temperature response of the body. In addition, the temperature difference between indoor and outdoor in winter is large, and direct blowing may also cause colds and other conditions.

Pay attention to the insulation of the room

For some rooms with poor door and window structure and large gaps, some emergency improvements can be made. For example, use glue paper tape to seal the window gap, stick a layer of transparent plastic film outside the glass window, stick wood wool plastic board on the indoor wall, use sun-shading curtains, and paint the white paint on the outside wall to reduce the cold consumption of the exterior wall. Ensure the insulation of the space and avoid the energy loss of the central air-conditioning.

Ensure fresh indoor air

When using the air conditioner, in addition to avoiding the loss of heat in the gaps between the walls and windows, it should also be noted that when the air conditioner is turned on for a period of time, the indoor air will not circulate and a large amount of bacteria and dirty air will accumulate, so that the windows should be opened for ventilation in time. Of course, in addition to opening windows for ventilation, you can also choose to install a central fresh air system or a wall-mounted fresh air system, which can help replace the dirty indoor air and outdoor fresh air for 24 hours without opening the window in winter, and filter harmful substances.
