The temperature setting of the wall-mounted split air conditioner must be kept within a reasonable temperature range, that is, it should be 26℃～28℃ in summer and 18℃～20℃ in winter. The temperature of the wall-mounted split air conditioner should not be too different between indoor and outdoor, generally 5℃～10℃. If the temperature difference is too large, you will experience sudden changes in temperature when entering and exiting, and you will be prone to colds and other diseases.
Generally, the installation position of the wall-mounted split air conditioner should avoid the heat source, and the hot air removal and noise interference should not affect the neighbors. The installation height of the outdoor unit should be lower than the indoor unit, which is conducive to the circulation of refrigerating oil. The outdoor unit should be installed without short-circuit circulation of hot air, so as not to affect heat dissipation: the installation location should be conducive to maintenance, easy to drain and not affect pedestrians, avoid or stay away from high-voltage lines, places with radiation, and flammable and explosive places. There should be no obstructions in front of the indoor unit, and the jet distance of cold air (or hot air) should be ensured to make the indoor temperature more uniform.
