When cooling in summer, when the temperature is set at 26~27 degrees Celsius, the cooling load can be reduced by more than 8%. When heating in winter, setting the temperature 2 degrees Celsius lower can also save electricity10%; When people sleep, their metabolism decreases by 30%~50%. Setting the air conditioner in the sleeping area and raising the temperature by 2 degrees Celsius can save electricity by 20%.
For people who sit still or work lightly, if the room temperature is kept at 28~29 degrees Celsius and the relative humidity is kept at 50%~60%, people will not feel stuffy or sweaty, which belongs to the comfortable range.
Extended data
In the heating mode, the air conditioner uses a component called a four-way valve to make the flow direction of freon in the indoor unit and outdoor unit opposite to that in the cooling mode, that is, the circulating flow direction of refrigerant is compressor-indoor unit-outdoor unit-compressor.
At this time, the functions of the indoor unit and the outdoor unit are also reversed, that is, the indoor unit acts as a condenser to cool the superheated steam in the cold room and release heat, and the indoor cold air is turned into hot air by the fan, so that the air conditioner achieves the effect of heating. The outdoor unit acts as an evaporator, so cold air is blown out.
