  • Patent number: 4517958
    Abstract: This invention is an energy efficient heating and cooling system. It is particularly adapted for use in conjunction with building type structures. Both liquid and gaseous fluids can be circulated at the same time through the heat exchange means. These exchangers can be either separately attached units or can form an integral part of the building structure itself. The exchangers are mounted on both northern and southern exposures and can accomplish a combination of functions either separately or at the same time to meet varying energy demand situations.
