The reduction of the re-thermal energy by the coolant exhaust heat use for air conditioning The coolant temperature when the coolant for air conditioning returns to the cooling tower exceeds 30°C. We collected the exhaust heat of this coolant and assumed it the warm temperature source of the re-heat driving and planned heavy oil and electricity reduction in the summer. The exhaust heat collection system flow
