The EEV Control of the Multi-type Air-conditioning System by using a Fuzzy Logic Superheat Temperature Setpoint Reset Algorithm |
| Abstract |
Refrigerant flow rates of the multi-type air-conditioning system can be regulated by electronic expansion valves(EEV). The performance of the multi-type air-conditioning system may be improved by lowering the superheat at the compressor suction side. In this study, a superheat temperature setpoint reset algorithm was developed by using fuzzy logics, and a PI algorithm was applied to control the superheat temperature near setpoints. Experimental results showed energy savings and stable operations at a multi-type air-conditioning system. Therefore, the developed setpoint reset algorithm may be effectively used for the EEV superheat temperature control of the multi-type air-conditioning system. |
