This paper deals with the two systems for supplying both 85℃-high temperature water and 55℃-medium temperature water in the total heat supply system using CO2-heat pump. One of them has a two-divided gas cooler and a pre-cooling sub-system on the basis of the conventional refrigerating cycle, and the other has a three-divided gas cooler. The COPs and hot water flow rates of both two systems are calculated. As a result, it is shown that both systems are capable of supplying 85℃-high temperature water and 55℃-medium temperature water to satisfy the typical industrial heat demand.
