Abstract: The disclosure relates to an improved venting arrangement for a solar energy collecting device of the type wherein a double walled tubular-type structure is employed with the outer wall of the inner tube carrying a solar absorbent coating and the interior of the inner tube being periodically filled with a heat transfer fluid. To prevent such heat transfer fluid from completely filling the inner tube, and thus establishing an undesirable siphoning action, and to concurrently permit the unrestricted venting of air out of the inner tube during filling and into the inner tube upon drainage of the fluid therefrom, this disclosure provides a vent tube extending into the upper regions of the inner tube and having a floatable valve structure mounted on its upper end and arranged so as to effect a seating of the valve and the closing of the vent tube when the fluid level in the inner tube reaches a desired height.

Abstract: The invention disclosed is a liquid constant flow, drainable solar energy collector system in which a manifold feeds several evacuated glass tube solar collectors disposed on an upward side of the manifold. The collectors are fed in parallel through an individual orifice which restricts flow rate to each solar tube. The normal outlet of each solar tube is via an axial glass pipe which extends to its top region. The orifices are all connected to a common header pipe in the manifold and the glass outlet pipes are all connected to a separate common header pipe in the manifold. For each solar tube the outlet pipe is of sufficient diameter in relation to the orifice so liquid that overflows the pipe does not completely fill it thereby always allowing an air vent passage via the same pipe. The restricted orifices are provided by inserts removably installed between their common header pipe and each of the solar tubes.

Abstract: The invention is a solar energy conversion apparatus in which several evacuated, glass tubular collectors are connected together in a liquid circulation system for controlled movement of a liquid between the interior of the collectors and a storage tank. Liquid circulation is controlled by sensors and switches therefor in regulating operation of valves and/or a pump. The conditions for circulating the liquid rely upon (1) sensing a need for energy at the storage tank, (2) sensing solar radiation availability, (3) sensing thermal conditions in the solar collector tubes to avoid high temperature and thermal shock, and sensing a need to withdraw hot liquid and add more.

Abstract: There is disclosed a solar energy operated system and method in which a quantity of liquid media is placed in solar collectors and heated to a preselected temperature therein. Upon reaching this temperature, the liquid is transferred to a first storage vessel. The liquid is replaced in the collectors from a separate second storage vessel. The hot liquid is drawn from the first vessel and circulated to a heat exchanger of a heat operated device, such as an absorption refrigeration device or a space heating device, and heat is exchanged thereby to operate such device. The liquid is returned from the heat exchanger of the device to the second storage vessel so as not to thermally contaminate the higher temperature liquid processed by the solar collectors. This is termed a batching method of operating the solar energy collectors in the system.
