Abstract
A solar heating and cooling system comprising a double tiered solar collector and heat exchanger that is mounted on a roof at an angle ranging from 30.degree. to 45.degree. with respect to the horizontal, with its upper surface being blackened. Each tier of the heat exchanger includes a series of longitudinal channels, there being upper and lower manifolds communicating with all of the channels. A duct depends from the middle of the upper channel and is connected to an air blower that takes air from the premises being heated or cooled. Another pair of ducts depend from the lower manifold at the opposite end thereof and discharge heated air into the premises. A heat trap in the form of a transparent plastic sheet is removably mounted above the collector and heat exchanger in close proximity thereto.
Claims12
In a solar heating and cooling system intended for installation in premises to heat or cool the air therein, said premises including a roof and supporting structure therefore,
- a. a solar collector and heat exchanger including a flat metallic sheet and a grooved metallic sheet secured to said flat sheet to provide a plurality of longitudinal channels which have a vertical component when said exchanger is mounted on said roof;
- b. an upper manifold communicating with said channels at the upper ends thereof;
- c. a duct depending from said upper manifold and extending into said premises;
- d. an air blower within said premises connected to said upper manifold;
- e. a lower manifold communicating with said channels at the lower ends thereof;
- f. a duct depending from said lower manifold and having a discharge end in said premises;
- g. a heat trap in the form of a flat transparent sheet removably mounted on said heat exchanger;
- h. an arrangement of spray pipes mounted above said heat exchanger in spaced relation and substantially parallel thereto;
- i. a source of water;
- j. means for introducing water under pressure from said source into said spray pipes, and,
- k. a retractable sunshade mounted on said roof over said arrangement of spray pipes in a position substantially parallel to said exchanger;
- whereby said sunshade may be retracted into a position exposing the upper surface of the grooved sheet of the heat exchanger to rays of the sun and the heat trap positioned over said heat exchanger for heating purposes or the heat trap removed from position covering said heat exchanger and the sunshade extended into position protecting said arrangement of spray pipes and exchanger for cooling purposes.
