증발냉각 응축기 기반 공기열원 히트펌프의 에너지 절감 효과 분석

Abstract

The main purpose of this study is to investigate the energy saving potential analysis of a spryed-condenser assisted air-source heat pump used in an office building during summer season. A direct evaporative cooler was installed on the inlet side of the condenser to enhance the heat exchange performance. The hot ambient air was introduced to the direct evaporative cooler and cooled nearly wet bulb temperature by evaporative cooling effect. The cooled air treated by direct evaporative cooler was introduced to the condenser. A energy recovery ventilation was installed for ventilation of the occupants, and all of the sensible and latent load of the office building is removed by the proposed and existing heat pump system. The simulation was conducted by Engineering Equation Solver (EES) and TRNSYS 18 for model building thermal load simulation. The result was showed that proposed heat pump system is saved 26.4% of primary energy consumption than existing heat pump system in summer. This can be solve the problem of maximum power demand and overheating in summer with simple installation.
