Abstract The heat interchange is one of the effective methods for saving energy of the air conditioning systems, but there are few examples. Therefore, it is important to introduce this method by revealing how... effective it is. The purpose of this study is to clarify the efficient control method of heat interchange between two district heating and cooling systems. In this paper, control tables for interchange of cold water and hot water based on case studies are proposed. If the tables are applied, the system COP will be improved 4.73% through a year. However, there is a problem that these tables cannot improve the efficiency in summershow more
