The purpose of this report is to develop a scheme for optimal placement of outdoor condensing unit. With this purpose, we examine the relationship between rise in suction temperature and the placement of outdoor condensing unit in multi-level installations. In particular influence of exhaust duct is examined. A model experiment is performed for outdoor condensing. In addition, an equation for predicting rise in suction temperature for outdoor unit having an outside-air inflow rate R_m (ratio of outside-air inflow volume to air volume of the outdoor unit) is used to clarify the relationship between the rise in suction temperature of outdoor unit and equipment setup conditions. Based on these results, factors that will determine setup conditions considering the rise in suction temperature of outdoor unit are found and a method for suppressing rise in suction temperature is evaluated.
