Control of multiple air-conditioner

Abstract

Abstract PURPOSE:To control the rotation of a compressor in accordance with an air- conditioning load by a method wherein the revolving number of the compressor is controlled by increasing or decreasing the frequency of an electric source in accordance with the integrating value of time until arriving at a set temperature as well as the number of sets of operating indoor heat exchangers. CONSTITUTION:During the operation of a refrigerating cycle upon one-room operation, the operating time of one room itself is integrated. When the temperature of the room has arrived at the set temperature without first set time TB, the operating frequency of the compressor is decreased. When it has arrived at the set temperature within the second set time TA, the operating frequency command is kept as it is. When a set temperature arriving signal is not outputted after the second set time TA has elapsed, the operating frequency of the compressor 10 is controlled so as to be increased at every third set times. When the operation is transferred to two-room operation, the compressor is controlled so as to be operated by the frequency, in which a given frequency is added to the operating frequency of the compressor upon one-room operation.
