No, the air conditioner will emit heat (through hot air) while cooling, which is necessary for refrigeration operation. If no exhaust duct is installed, the heat will be discharged indoors.
Moreover, the installation position of air conditioners should not be low. Some families install air conditioners on the windowsill, which is not conducive to reducing the operating rate. According to the principle of "cold air goes down and hot air goes up", the air in the lower floor of the room is mixed with cold and hot air, while the air in the upper floor of the room is high temperature. If the air conditioners are installed on the windowsill, the temperature of the extracted air is low, and relatively speaking, the air conditioners are doing reactive loss, and the hot air in the upper floor is not effectively cooled.
therefore, the air conditioner should be installed on the upper part of the window facing the sun. In particular, don't install the air conditioner hanging machine too close to the outdoor unit, which will easily cause vibration and noise.
