Abstract
The solar evaporator is comprised of a parabolic dish structure and the evaporator located just outside of the focal point. The refrigerant, coming from the heat pump, circulates through the evaporator. After having been heated up by the concentrated solar heat, the refrigerant is routed to the heat pump which compresses the refrigerant so as to extract the maximum amount of heat collected. The goal is to continuously maximize the temperature differential at the receiving coil by keeping the refrigerant at the lowest temperature possible in order to maximize heat gains at the evaporator. Multiple parabolic dishes can work together wherein they are connected in parallel to the header. A sun tracking mechanism ensures that the dishes are always pointing towards the sun. The extract heat can be used for multiple purposes.
