Two major problems that lead to low cooling efficiency in the engine room

One can not rely on the air conditioning to cool the door and window for a long time. Disconnect the window and keep the indoor air circulation to avoid lack of fresh air. Second, avoid

air conditioning switch back and forth, not only switch often damage the compressor, while the power consumption will be large.

three bogey too large indoor and outdoor temperature, indoor and outdoor temperature is preferably in the summer 5 ℃ ~ 8 ℃.

four bogey dirty equipment, air-conditioning and dehumidification device to be inspected and cleaned regularly, especially filter, it can really play a role filter dust, bacteria and harmful gases.

air conditioning fan is necessary to "sterilize" the main

air-conditioning fan vents and other places most likely to breed bacteria and other microorganisms. If it is not cleaned up in time, microorganisms such as bacteria will be blown into the air by cold wind, which will have an impact on human health.

Therefore, in the maintenance and use of air-conditioning fan, be sure to "sterilization" based. Try to add some pure water to the water cooling device, and also clean it once a week. In addition, when using an air-conditioning fan, try to keep a certain distance to avoid direct blowing of cold air to the body. If the air-conditioning fan

long-term idle, it is best to use plastic sheeting wrapped, placed in relatively dry air in place, so you can play the role of protection and maintenance.
