| Abstract |
In order to control multi-zone temperatures, a multi-type air-conditioning sys-tem may be used. In this study, control algorithms for the compressor and the electronic ex-pansion valve of a multi-type air-conditioning system were developed by using fuzzy logics. The compressor control algorithm was composed of a compressor pressure setpoint algorithm, a compressor pressure setpoint reset algorithm, and a compressor frequency setpoint algorithm. The electronic expansion valve control algorithm was composed of an indoor temperature con-trol algorithm, and a superheat control algorithm. These algorithms were applied to a multi- type air-conditioning system. Test showed good results for the control of a multi-type air- conditioning system. |
