Abstract
A heat-pump type air-conditioner includes a potentiometer provided to output a voltage corresponding to a position of a slidable terminal movable on a register element. Based on the magnitude of the output voltage, one of a cooling mode, a stop mode and a heating mode is set, as is the speed of the compressor consequently, both the modes selection and the temperature control can be performed with one switch operation.
Claims8
A control device for a climate control system which includes a heat exchange system including a heat exchanger, comprising:
- shifting means including one terminal for selectively shifting the heat exchanger into one of a cooling mode, a stop mode and a heating mode, while also controlling a temperature of air output by the system within said modes, based on a position of said one terminal, wherein said heat exchange system includes means for cooling air passing therethrough when said heat exchanger is shifted into said cooling mode and for heating the air passage therethrough when said heat exchanger is shifted into said heating mode, and
- wherein said terminal further comprises a resistor element to which a predetermined voltage is applied at both ends thereof, and means for mounting said terminal to be movable on and along the resistor element for outputting a voltage corresponding to its position on the resistor element, and
- wherein said control device further comprises control means for setting a revolution number of a compressor in each of the cooling and heating modes, based on the voltage output from the terminal.
