저부하 조건에서 히트펌프 증발압력 제어를 통한 열쾌적성 개선

In order to develop a control method that can be used to achieve better indoor thermal comfort and energy efficiency at a low cooling load condition than the current control method, a new method of the evaporation pressure control based on the evaporator outlet pressure reading(EPCP) was developed. Compared with the evaporation pressure control based on the evaporator outlet temperature reading(EPCT), the EPCP control method appeared to improve the stability of room air temperature or occupant thermal comfort significantly.
