Does the ordinary household air conditioner have ventilation function?
In fact, the air-conditioning air supply mode can only play the role of an electric fan, that is, it accelerates the flow of the original indoor air, and does not send fresh air from the outside, so it naturally does not have the effect of improving indoor air quality.
Few air-conditioning products have the function of ventilation. You can observe how many pipes are connected to the outdoor unit in the indoor unit. If there are only two copper pipes and a drain pipe, there is no ventilation function.
Cooling settings:
Judging from the start-up index of air conditioners in summer, 30-33℃ belongs to Grade 4, and 70% of people need to turn them on. 33-35℃ belongs to level 5, and 90% people need to turn it on. Pay attention to adjust the indoor and outdoor temperature difference after turning on the air conditioner. The room temperature should be set at about 24℃- 18℃, and the temperature difference between indoor and outdoor should not exceed 7℃.
When the air conditioner cools, the set temperature is about 26-28℃. In this case, not only the human body feels more comfortable, but also it is conducive to energy saving. Don't set the temperature too low when the air conditioner is cooling. When the room temperature is adjusted to 26-27 degrees, the cooling load can be reduced by more than 8%.
Experiments show that under normal circumstances, if the room temperature is kept at 28-29 degrees and the humidity is kept at 50-60%, people will not feel sultry and sweaty, which belongs to the comfortable range. When people sleep, their metabolism decreases by 30-50%, so they can set the air conditioner on the sleep switch and set the temperature to 1 degree, which can save electricity by 10%.
