In this article, we focus on the waste heat in the low temperature at the range of 30℃ to 40℃ generated from the water-cooled chiller which cools data centers. This study investigates the characteristics of the water-cooled chiller and the heating air conditioning system when operated individually and when operated in combination, assuming a coupled system in which the waste heat is recovered through heat exchange with the cooling water from the water-cooled chiller and used in the heating air conditioning system. As a result, it was found that the system using waste heat has an optimum point for the temperature of waste heat. In assessing, we were able to quantitatively demonstrate the most efficient method of using exhaust heat for air conditioning
