Abstract
A cooling/heating apparatus having an automatic ventilating function and its method switches the ventilating function and the cooling/heating function in response to the pollution state of room air and maintains the room air in a pleasant state. The apparatus and method rotates the cooling/heating fan and the ventilating fan to be mutually supplemented and completed by the output of a gas sensor which changes its resistance value in response to the air pollution state within a room. The ventilating fan is rotated instead of said cooling/heating fan when the room air is polluted and ventilates the polluted air within a room.
Claims18
In a cooling/heating apparatus having an automatic ventilating function;
- an apparatus comprising:
- a first motor for rotating a cooling/heating fan;
- a first motor driving means for driving said first motor;
- a second motor for rotating a ventilating fan;
- a second motor driving means for driving said second motor;
- a means for sensing an air pollution state within a room;
- and
- a control means (a) for alternately and selectively controlling said first motor driving means and said second motor driving means in response to the output of said pollution sensing means, and (b) for controlling a speed of rotation of said ventilating fan in response to the output of said pollution sensing means, said control means comprising a micro-computer.
A cooling/heating control method having an automatic ventilating function comprising:
- a process for inducing a cooling/heating operation demand;
- a process for sensing an air pollution state within a room by a gas sensor and rotating a ventilating fan so as to ventilate polluted air within the room in accordance with a sensed result and setting the cleanness standard value of an air within the room;
- a process for driving a cooling/heating fan so as to increase and decrease a temperature within the room instead of driving said ventilating fan and comparing the cleanness standard value with a state value of the air within the room sensed by said gas sensor at a predetermined period;
- and
- a process for driving the ventilating fan instead of driving said cooling/heating fan and ventilating the polluted air within the room when the resistance value of said gas sensor and said air cleanness standard value do not agree.
