Air source heat pump based on exhaust air of clean operation department and its performance studies

The air conditioning system of the clean operation department operates only by day,  it is suited for application of air source heat pumps. The average exhaust air temperature of clean operation department of hospital is about 22 ℃， so taking the exhaust air as heat source of air source heat pump can not only improve heat pump operating condition, but also increase heating COP, showing good development foreground.
