ABSTRACT:
The present invention relates to air conditioning systems and more particularly to an air conditioning system which provides air conditioning in each of a plurality of spaces. The air conditioning system according to the present invention divides a space with partitions into a plurality of air conditioning spaces and controls the temperature by cooling and heating mediums supplied from an external heat source using a three-way valve and an expansion valve. The air conditioning system includes an ID card for identifying a person which uses the air conditioning system. If a person is present to use the air conditioning system, the set or measured values of the environmental conditions for that person is stored. When that person again uses the air conditioning system, the system calculates the environmental conditions stored by the person in accordance with his stored set or measured environmental condition values. Each of the individuals' preferred comfortable environments is automatically realized by calculating the set values for that person in accordance with his current or past set conditions independent of the space. Changes to his preference to the environmental conditions are easily made.
