For the compressor speed control of a multi-type air conditioning system, a fuzzy control algorithm was developed. The sum of zone temperature errors and its derivative were used as input variables, and the compressor speed was selected as the output variable. To test the effectiveness of the control algorithm, one outdoor environmental chamber and four indoor environmental chambers were used. In the chamber, zone temperature step change tests and indoor unit changeover tests were performed. Test results show that, for the control of compressor speed, the fuzzy control algorithm is more effective than the conventional proportional control algorithm in the energy conservation.
