Constant temperature and humidity machine

Abstract

A constant temperature and humidity machine for automatically adjusting a room temperature and humidity to a desired room temperature and humidity based on a detected temperature and humidity of the machine. The machine includes silica tubes, a mistorizing system, and various components for flowing air in a heated state, a cooled state, and/or a moistened state. The machine also includes various sensors and circuits configured to detect a temperature and/or humidity in the room and automatically (or manually) activate and de-activate the silica tubes, the mistorizing system, and/or air flow components in the machine to adjust the temperature and/or humidity in the room to a desired temperature and/or humidity. Such mistorizing system produces ultrasonic frequencies to generate a mist from a water tank such that the particular ultrasonic frequencies generate an optimal droplet size for flowing moistened air from the constant temperature and humidity machine.
