Such constant temperature and humidity machine may be employed for automatically adjusting a room temperature and humidity level according to a detected temperature and humidity level in the room, detected by the machine. For example, a user may input a desired temperature and humidity (or moisture level) on the constant temperature and humidity machine. Such machine may then automatically adjust the room temperature and humidity levels to the desired levels by dispersing heat or providing a cooling effect, as well as modify moisture levels. In this manner, the constant temperature and humidity machine may modify the temperature and humidity within a room depending on the desired settings relative to the detected temperature and humidity within the room or given area which the machine sits. The dispersal of heat by the constant temperature and humidity machine may be provided with air flow over a heating element, such as silica tubes 21, which also may be in combination with a fine mist mixed with air to modify the humidity or moisture levels in the room. The cooling effect may be provided with a cooling element with, for example, air flow as well as in combination with a generated fine mist provided by the machine. The generated mist of the present invention may be provided with an ultrasonic mistorizing device 24 along with other components described herein, generating the fine mist with optimal droplet sizes that when mixed with air, the mist can provide an improved cooling effect and modifies the humidity and temperature in the room to desired levels.
