Vicot's gas absorption heat pump system uses natural gas as a clean driving energy. It uses MR717 as the refrigerant, and water as the absorbent, then, using a fin heat exchanger, this clean energy pump can extract the low grade heat energy from the air. The heating efficiency of this energy utilization equipment is 1.8 times better than gas boiler available on the market today, making it an efficient piece of energy utilization equipment.
