Abstract
A solar roof collector comprising a plate collector with a plurality of transparent conduits to channel a thin film of water from an insulated reservoir in order to increase the temperature of water therein as a result of heat absorption in the plate collector. An evaporative chiller including transparent air ducts in which air is circulated receives in the air ducts pre-heated water from the insulated reservoir, distributed therein preferably under the form of a thin film. Some water in the air ducts is vaporized and the vapor saturated air is passed through a vortex condensor, precipitating water which generates thermal energy. The thermal energy may be used to drive a gas turbine or another type of energy conversion device.
Claims25
A solar roof collector comprising:
- a high grade collector, including,
- a) a conduit to channel a heat absorbing working fluid;
- b) an ultra-violet focussing means coupled to said conduit for directing ultra-violet radiation toward said conduit, said focussing means being substantially transparent to infra-red and visible radiation;
- c) a first energy converter means in a fluid communication with said conduit to produce mechanical energy as a result of flow of heated working fluid therethrough;
- a low grade collector, comprising:
- a) an insulated reservoir for storing a light transmissive working fluid;
- b) a plate collector, including:
- i) a conduit means mounted under said high grade collector, said conduit means transmitting visible radiation;
- ii) means to flow working fluid from said insulated reservoir through said conduit means and back to said insulated reservoir to increase the temperature of working fluid in said insulated reservoir as a result of heat absorption by working fluid flowing in said conduit means;
- c) an evaporative chiller, including;
- i) an air duct transmitting visible radiation;
- ii) means to create an air flow through said air duct;
- iii) means to flow working fluid from said insulated reservoir through said air duct and back to said insulated reservoir to cause vaporization of working fluid in said air duct;
- iiii) condensing means in fluid communication with said air duct for receiving vapour containing air, said condensing means precipitating working fluid to produce heat;
- d) as second energy converter means thermally coupled to said condensing means for producing mechanical energy as a result of thermal energy received from said condensing means.
