What is the outdoor temperature before the air conditioner starts heating?

Air conditioning heating depends on the set temperature. When the outdoor temperature is 20 degrees, the air conditioner should be set above 23 degrees. However, when the mode is switched to heating, the air conditioner needs a period of preheating. When the temperature reaches the preset temperature of the temperature sensor, the air conditioner can operate and the fan blows out hot air.

Air conditioning is air conditioning. Refers to the equipment that manually adjusts and controls the temperature, humidity, cleanliness, flow rate and other parameters of the ambient air in the building/structure.

Generally, it includes cold source/heat source equipment, cold and hot medium transmission and distribution system, terminal device and other auxiliary equipment. It mainly includes refrigeration host, water pump, fan and pipeline system. The terminal equipment is responsible for carefully handling the air state by using the cold heat from transmission and distribution, so that the air parameters of the target environment can meet the requirements.

Extended data:

There are ten points for attention when using air conditioning:

1, the power supply voltage should not fluctuate too much (10% fluctuation is allowed), the air conditioner should be powered by a dedicated line, and the single-phase three hole socket should be used, and the plug should be plugged to the end.

2. The casing of the indoor unit should be cleaned frequently. Generally, it can be wiped clean with a clean dry cloth or neutral detergent. It is absolutely not allowed to rinse directly with water. If it is wiped with a cloth, it should be done after the power is cut off.

3. The indoor temperature should not be adjusted too low, otherwise it will be harmful to human body, and the set temperature should be adjusted appropriately.

4. If you feel that the indoor temperature is too high, you can lower the set temperature appropriately.

5. The effective use of timer can achieve the effect of energy saving and comfort.

6, air conditioning room personnel should not be too much, too crowded, otherwise the cooling capacity is insufficient, the temperature is difficult to drop;

7. Don't switch the doors and windows of the room frequently, and people don't go in and out frequently to avoid the loss of air conditioning;

8. The glass window must be closed tightly and tightly, and double white curtains should be hung inside to reflect the partially penetrated light and heat;

9. The window can be opened briefly during indoor ventilation, and the window opening time generally does not exceed 10 minute;

10, the air filter should be cleaned regularly, otherwise the airflow is blocked, resulting in insufficient air volume and rising room temperature;
