Study on Control of Refrigerant Flow Rate and Characteristics of Superheat in Evaporator using Electronic Expansion Valve
- 발행 : 1994.11.01
초록
An experimental study was performed to investigate the characteristics of refrigerant flow rate control and superheat in an evaporator with an electronic expansion valve(EEV). The EEV used in this study was devised using a needle valve coupled with a stepping motor controlled by a personal computer. A Pill control equation was used to control the superheat of the evaporator and to set the superheat to
