Title: Improved solar heating systems

Abstract

An improved solar heating system is described in which the incident radiation of the sun is absorbed on collector panels, transferred to a storage unit and then distributed as heat for a building and the like. The improvement is obtained by utilizing a storage unit comprising separate compartments containing an array of materials having different melting points ranging from 75 to 180/sup 0/F. The materials in the storage system are melted in accordance with the amount of heat absorbed from the sun and then transferred to the storage system. An efficient low volume storage system is provided by utilizing the latent heat of fusion of the materials as they change states in storing ad releasing heat for distribution.

  • A control circuit for controlling the fan or circulating pump in a solar-thermal heating system to prevent unnecessary pump or fan switching when short-term interruptions occur in the insolation of the solar panels includes a temperature-sensitive time-delay element tailored to have thermal response characteristics corresponding to those of the solar panels in the system.
  • A solar powered fluid heating system is described comprising: a predetermined quantity of refrigerant; a thermal collector assembly for heating the refrigerant, comprising; separator means for receiving heated refrigerant from the thermal collector assembly and for separating the vapor component of the heated refrigerant from any liquid component thereof; a condenser for receiving the vapor component of the heated refrigerant from the seperator means; a supply of fluid to be heated; means for transferring heat from the refrigerant in the condenser to the fluid and thereby returning the refrigerant vapor to the liquid phase; vapor conduit means extending from themore » separator means to the condenser; liquid conduit means extending from the condenser to the thermal collector assembly; the thermal collector assembly, separator means, condenser, vapor conduit means and liquid conduit means comprising a closed refrigerant circuit which contains the predetermined quantity of refrigerant; and refrigerant pressurizing means for causing the refrigerant to flow through the refrigerant circuit.« less
  • A system is disclosed for heating a building adapted to confine animals includes a solar collector, means for storing the heat absorbed by the collector and heat radiating floor mats which use such heat. The collector includes panels each having lightweight, clear, parallel plastic tubes secured at their ends to headers of similar material. The tubes are disposed in troughs in the panel base having inclined reflective side walls to concentrate reflected solar energy on the tubes. The heat radiating floor mats comprise tubes and headers like those used in the solar collector panels.

  • A solar heating system includes a solar collector consisting of a continuous length of copper tubing coiled into a helical array of closely adjacent turns and supported within a sealed housing. The outer turns of the array are fabricated of tubing having a greater diameter than the tubing which forms the inner turns of the array. The total length of the larger diameter tubing in the array is greater than that of the smaller diameter tubing. The relationships between the tubing diameters and lengths are selected to achieve a desired flow rate and temperature rise for the overall array. Themore » array is supported within the housing by copper sheets which also operate to eliminate moisture condensation within the housing.« less
