Haier air conditioning can't be used at MINUS several degrees in the north.

Haier air conditioning can't be used at MINUS seven degrees in the north.

When the outdoor temperature reaches -7℃, the domestic air conditioner is not a "strike", but the heating effect is greatly reduced. Because air conditioning is mainly a process of air convection, its refrigeration and heating depend on the compressor and refrigerant (such as freon) of the external machine, and hot air or cold air is generated through their high temperature and high pressure or low temperature and low pressure.

The rotary operation of air-conditioning compressor has a temperature range. If the temperature is too low, its cold-hot conversion rate will be greatly reduced. From the description of physical properties, -7℃ has almost become the critical point of household air conditioning. "The temperature is low, its heating effect is poor, and it takes a long time to heat up indoors.

Extended data

When air conditioning heats, it absorbs heat energy from outdoor air and converts it into indoor air. But if the outdoor temperature is too low, the heating effect of the air conditioner will be poor. Therefore, many air conditioners use auxiliary electric heating, that is, electric heating pipes are added to the indoor unit to achieve ideal heating effect.

The design of electric auxiliary heating is actually to improve the heating effect of air conditioning in cold weather. The air conditioner with electric auxiliary heating heats up faster, while the air conditioner without electric auxiliary heating heats up slightly slower.

In addition, the electric auxiliary heating of the air conditioner can be turned on and off manually, and the remote controller is equipped with function buttons, which generally have the words "auxiliary heating". However, it should be noted that turning on electric auxiliary heating will inevitably increase the energy consumption of air conditioning, and everyone should combine the actual situation of their own temperature when using it.

People's Network-The minimum working temperature of air conditioner passing through the network is -7℃. Expert interpretation: This is true!

People's Network-It's also comfortable in another way. After stopping heating, only air conditioning can save electricity.
