The present invention relates to an air conditioner for constant temperature and humidity, and more particularly, in the air temperature and humidity air conditioner used for use in clean rooms and industrial precision manufacturing requiring constant temperature and humidity, according to seasonal characteristics such as summer and winter. Therefore, by changing the structure and device of the air conditioner where outdoor air and indoor circulating air are sucked and mixed into the air conditioner, the constant temperature and temperature at which the outdoor and indoor air that has passed through the air conditioner regardless of the season at a low energy level can always maintain a constant humidity and temperature. To provide a humidistat.

Particularly, in the constant temperature and humidity treatment process of external air and indoor circulation air, it is a low energy consumption type that can perform constant temperature and humidity of external air and indoor circulation air while using low energy in an integrated air conditioner that is not separated. An integrated constant temperature and humidity air conditioner is provided.

Conventionally, the air conditioner used for the above purpose is to suck and mix external air and indoor circulating air at the same time to the mixing chamber 4 of the air conditioner body 1 as shown in FIG. 6 for the constant temperature and humidity treatment of outdoor and indoor air. In this structure, the external and indoor circulating air mixed as described above is dehumidified and cooled through the cooling coils 52 for dehumidification and cooling via the filters 23 and 24, and then through the fitting coil 53. It is a system that discharges the air through the air outlet (8) after raising the temperature, and when the air of the atmosphere has a lot of humidity such as summer, mixed air is mixed with high humidity outside air and indoor circulating air. The humidity of the room should be adjusted to the humidity required in the room, the cooling coil 52 is operated for a long time, the energy consumption is excessive, and the mixing is cooled through the cooling coil 52 as described above Since the temperature of the air must be increased to the target temperature, reheating must be performed regardless of the atmospheric temperature such as summer and winter, resulting in excessive energy consumption and humidity conditions when controlling the humidity and temperature of the mixed air. Regardless of the high temperature, the cooling coil is operated to cool down and dehumidify, and the dehumidification operation is unnecessary even when the humidity of the mixed air is appropriate or low, and energy must be re-humidified through a separate humidifier.
