Is it too hot to cause the air conditioner not to cool?

Too hot weather will cause the air conditioner not to cool.

If the outdoor temperature is too high, it will be more difficult for the air conditioner to cool the indoor air to the preset temperature. At this time, the air conditioner takes longer to cool, and may need to consume more electricity. By adjusting the air speed and temperature settings of the air conditioner, the refrigeration effect of the air conditioner can be improved.

At the same time, when the outside temperature is too high, by improving the shading degree of indoor glass windows and keeping indoor doors and windows closed, indoor heat can be prevented from being lost through windows and doors and windows, thus assisting air conditioning refrigeration.

The temperature of the condenser reaches above 50℃, far exceeding the heat dissipation capacity, which is most likely to happen in the environment where the outdoor unit is directly exposed to the sun. In many places, the noon temperature is as high as 50℃. If the outdoor air conditioner is directly exposed to sunlight, the temperature will be above 50℃. If the outdoor unit of the air conditioner is exposed to direct sunlight, the temperature of the internal condenser will be above 50℃, which far exceeds the refrigeration capacity of condensation, and the air conditioner will not work normally.

The outdoor temperature of air conditioner is as high as 50℃, which far exceeds the heat dissipation capacity of condenser. At this time, the compressor will overheat and cannot be cooled normally.

Principle of air conditioning refrigeration;

The compressor compresses gaseous Freon into gaseous Freon with high temperature and high pressure, and then sends it to the condenser (outdoor unit) for heat dissipation, and turns it into liquid Freon with normal temperature and high pressure, so the outdoor unit blows out hot air.

Liquid Freon enters the evaporator (indoor unit) through the capillary, the space suddenly increases and the pressure drops, so the liquid Freon will vaporize and become gaseous low-temperature Freon, thus absorbing a lot of heat, and the evaporator will become cold. The fan of the indoor unit will blow out indoor air from the evaporator, so the indoor unit will blow out cold air.

Water vapor in the air will condense into water droplets when it meets a cold evaporator and flow out along the water pipe, which is why air conditioners produce water. Then the gaseous freon returns to the compressor to continue the compression cycle.

When heating, there is a component called four-way valve, which makes the flow direction of freon in condenser and evaporator opposite to that in refrigeration, so when heating, cold air is blown outdoors and hot air is blown indoors.
