Solar energy air conditioning system with storage capability

摘要

The invention utilizes concentrated solar energy in a novel air conditioning system which includes storage capabilities. The refrigerant circuit “high” pressure side is comprised of multiple solar concentrators placed between two positive rotary valves. The “low” pressure side is compromised of the evaporator coil with expansion valve. The refrigerant is confined between the two rotary valves. As solar energy is absorbed into the refrigerant, the pressure and temperature rise. The two rotary valves are then caused to rotate. With rotation, the refrigerant is moved through the circuit. The circuit also includes a condenser to give up heat and an evaporator/expansion valve in which temperature drops with the expanding gas. In addition, this system places the evaporator in a water tank. The water is made cold by conduction with the evaporator and serves as a storage medium. All energy absorbed is converted to cold and stored and utilized as required.
