摘要:
A water tank that is used with a solar air conditioning system and provides a supply of cold water for in-dwellings radiators of the system. In one embodiment, the tank application can begin at 32 F degrees and drop down to many degrees colder, such as, but not limited to, minus 100 F degrees. In one non-limiting embodiment, the tank can hold 2000 gallons of water.

Technologies are disclosed herein for a thin heat exchanger through which coolant may be pumped. The heat exchanger may include an envelope and a heat conduction layer provided over the envelope. The envelope may include one or more channels formed therein. The channels formed between the envelope and the conduction layer may extend the length of the heat exchange layer and be configured to carry coolant therethrough. The heat exchange layer may include an inlet manifold on a first end and an outlet manifold on another end opposing the first end. The inlet manifold may allow the flow of coolant into the heat exchange layer and the outlet manifold may allow the removal of the coolant from the heat exchange layer. Coolant flow may be controlled by a suction pump operating under computer control based at least in part on sensor data.

Heat transfer fluid in vapor only state is cycled through solar collector(s) (12) and a sensible heat storage medium (14) to transfer heat from the solar collector(s) (12) to the sensible heat storage medium (14). The heat transfer fluid is a liquid at ambient temperature, but substantially in the vapor state throughout the entire cycle when in operation.

The present application discloses a method and an apparatus for solar power generation through gas volumetric heat absorption based on characteristic absorption spectrum. A radiation energy conversion device absorbs concentrated solar radiation and converts radiation energy into thermal energy; the thermal energy is transferred to the other side of the radiation energy conversion device and then is converted into radiation energy; and the energy is transferred in a receiver cavity. The working gas from the outlet of a recuperator flows into the receiver cavity and absorbs the radiation energy. The heated working gas with high temperature flows into a turbine, doing shaft work through expansion. The expanded working gas flows through the recuperator to exchange heat. The working gas flows into a cooler, a compressor and the recuperator in sequence, and then flows into a receiver cavity to be heated volumetrically, completing a thermal power cycle.

A radiation thermal absorber based on characteristic absorption spectrum, a Stirling engine and an operation method thereof. The radiation thermal absorber allows working gas in the Stirling engine to absorb radiation heat quickly, and help the Stirling engine adopt assistant heating to ensure steady operation when solar power is not enough. The radiation thermal absorber includes a heater base, a radiation energy conversion device, heating tubes, a combustion chamber and valves of the heating tubes. The radiation energy conversion device converts the solar energy into radiation energy near a characteristic absorption peak of the working gas, and the working gas absorbs the radiation directly in depth.

A wind powered device incorporates a solar furnace and vortex generator to provide additional power and boost the efficiency of the complete system. Two concentric dome assemblies connected by a centrally located shaft are connected to a base with bearings capable of rotating the whole assembly 360.degree. about a vertical axis to allow it to turn into the wind. The two domes form a furnace, an inner dome providing insulation for a solar boiler and an exterior dome refracting the incoming sunlight onto the solar boiler. The solar boiler is located at the center of the inner dome and generates steam to drive fans positioned at the poles of the outer dome. The outer dome also functions as a wind powered rotor. Inlet vanes at the periphery of the dome are open to the atmosphere. The exterior of the dome is provided with trapezoidal or curved channels at regular distances parallel to the path of rotation. These channels effect lift by the venturi effect. They also channel the light to the center of the dome. Fans on the shaft evacuate air from the inside of the dome through openings located at the poles of the outer dome. As air is pulled through the outer dome and through the inlet vanes the outer dome will rotate. The system operates simultaneously as a solar furnace, a wind powered generator and as a vortex generator.

The invention relates to a pump and control unit for a solar heating installation system for a water tank, particularly for a swimming pool. The system contains a solar collector, a hydraulic circuit which includes an outward-flow pipe, a return-flow pipe, a pump, a derivative-action control unit and two sensors mounted on the outward-flow pipe and on the return-flow pipe, respectively. The pump, the control unit and the two sensors are integrated into a single case. The case is provided in its top wall with a transparent opening which faces the return-flow sensor and through which said sensor can be exposed to solar radiation, such that the pump may be automatically activated during periods of sunshine, i.e., when the solar collector is heating the water returning to the tank, and stopped due to lack of sunshine.
摘要:
A method of storing thermal energy in a body which is in direct thermal contact with the surrounding earth. The energy is transferred to said ground body from heat absorbing devices, specifically solar heat absorbing devices, by circulating a liquid in a circuit incorporating a plurality of channels in the ground body and said heat absorbing devices. The thermal energy stored in the ground body is removed therefrom by means of the circulating liquid and used to control the heat of an object such as a building by circulating the heated liquid around the building in a further circuit incorporating further channels and heat emitting devices. The channels in the ground body are arranged and sized in accordance with the calculated amount of thermal energy supplied to and taken out of the ground body period such as one year. A defined surface surrounding the ground body is established at a distance from the most remote of the channels in a direction outwardly of the ground body so to reach a maximum temperature on the order of 35.degree. C. and a temperature variation during the period of energy input and output of not more than 10.degree. C.
