Common sense of using air conditioning in extreme rain and snow!

At present, most mainstream brand air conditioners on the market have a minimum working temperature of -3°C to 7°C, and even some brands of heating outdoor units will freeze at 0°C! The editor below is going to zoom in! Offer the most professional extreme rain and snow weather air conditioner to use common sense to watch.

Common sense 1
Weather with low temperature and high humidity will increase the heat exchange and frosting of the outdoor unit of the air conditioner, and the heat exchange effect will be worse. Therefore, the heating effect of the air conditioner will decrease.

Common sense 2
In order to ensure the normal operation of the air conditioner, the air conditioner itself has an automatic frosting function. The defrosting function, simply put, is a short "cooling operation" (the indoor unit does not blow out), allowing the outdoor unit to become a condenser for a few minutes, allowing the high-temperature refrigerant to defrost its own frost, and then automatically resume the system Hot running.

Common sense 3
The defrosting process is automatic and cannot be controlled manually. In addition to causing the heating effect to decrease, it will also cause the indoor unit to have no hot air, the outdoor unit to emit white smoke (water vapor), the outdoor unit to flow black water, the venting sound (caused by the four-way valve switching), etc., these are all normal phenomenon.

Common sense 4
Do not cut off the power supply of all air conditioners, and require continuous power supply to ensure that the outdoor unit crankshaft heater can continue to heat the compressor and ensure that the refrigerating oil does not freeze for good lubrication.

Common sense 5
For air conditioners with a water system (multi-function VRV, etc.), please ensure that the power is supplied or take other measures according to the instruction manual. Otherwise, the protection function will not operate, and the low temperature below the freezing point may cause the water system to freeze. When the water freezes It will expand in volume and freeze the board, water pipe or fan coil.

Common sense 6
The outdoor unit should be well ventilated to prevent the snow from burying the outdoor unit, and prevent the falling of snow from damaging the fan blades of the outdoor unit. Sometimes the snow can freeze the fan blades of the outdoor unit and cause the air conditioner to not work properly.

Common sense 7
Air conditioners are high-current electrical equipment and should be powered separately, and all power cords should not have connectors. If there are connectors or sparks on the socket plugs, be sure to check and dispose of them.
