Abstract

The cooling load in winter season is significant in many commercial buildings and hotels because of the usage of office equipments and high efficiency of wall insulation. The development of a multi-heat pump that can cover heating and cooling simultaneously for each indoor unit is required. In this numerical study, a 4-room simultaneous heating and cooling heat pump system was modeled and its performance was calculated at each operating mode. Also, performance analysis was compared with experimental results.
