  • Air conditioned headgear and air conditioned clothing
    Patent number: 9175887
    Abstract: The present invention provides an air conditioned headgear and clothing. The headgear includes a thermoelectric cooling module and a control chip. The control chip includes a power supply circuit to supply driving current to the thermoelectric cooling module. The inner temperature of the headgear, the temperature of a heat sink, and the environmental temperature are sensed. A microcontroller of the control chip controls the power supply circuit to provide the driving current to the thermoelectric cooling module via processing the inner temperature of the headgear, a preset temperature, the temperature of the heat sink, and the environmental temperature using the PID control. In the present invention, the temperature is controlled using the PID control, thus wide fluctuations of the temperature is avoided, energy can be used effectively, and thermal cycle can be avoided.
