Will being too cold affect air conditioning and heating?

When the outdoor temperature is low, it is more difficult for the air conditioner to absorb heat from the outdoor air environment, resulting in relatively poor heating effect.

When the air conditioner heats in winter, the air conditioner absorbs the heat of the outdoor air through the heat exchanger of the outdoor unit, and then transfers the heat to the room through the heat exchanger of the indoor unit. Meanwhile, when heating, the outdoor heat exchanger is used as an evaporator. When the outdoor temperature is below -5 degrees,

The temperature difference of heat exchange between condenser and outdoor air will be close to 0. Therefore, there is no heat exchange effect, which leads to poor thermal effect of the air conditioning system and even no heating. Therefore, it is necessary to turn on the auxiliary electric heating function of the air conditioner or adopt other heating equipment.

Extended data

When the air conditioner is heating, the gas Freon is pressurized by the compressor to become high-temperature and high-pressure gas, which enters the heat exchanger (condenser at this time) of the indoor unit, condenses, liquefies and releases heat to become liquid, and at the same time heats the indoor air, thus achieving the purpose of increasing the indoor temperature.

The liquid freon is decompressed by the throttling device, enters the heat exchanger (evaporator at this time) of the outdoor unit, evaporates, absorbs heat by vaporization, becomes gas, and absorbs the heat of outdoor air (outdoor air becomes cold). Freon, which turns into gas, enters the compressor again and starts the next cycle.
