Title:
AIR CONDITIONING APPARATUS
Document Type and Number:
Japanese Patent JPH0735392
Kind Code:
A
Abstract:

PURPOSE: To speed up the building-up of an air conditioning apparatus in the starting of its operation by operating a variable capability compressor with the total value of substantially the same base capability as that of an indoor unit and additional capability set on the basis of the temperature of an indoor heat exchanger.

CONSTITUTION: The total value of capabilities of indoor units 21, 22 under a thermo-on state is calculated and is set as a base capability. In contrast, temperatures of indoor heat exchangers 91, 92 are detected by second sensors 171, 172, and an additional capability is estimated on the basis of a largest value of the detected values. The total sum of the additional capability and the foregoing base capability is taken as an operation capability. Further, operations of compressors A, B, C (outdoor units 11, 12) are effected on the basis of the operation capability. Further, temperatures of the indoor heat exchangers 91, 92 are again detected by the second sensors 171, 172, and the operations of the compressors are controlled on the basis of the detected values, whereby any of the indoor heat exchangers 91, 92 is control led to be a temperature of 53-56.
