Abstract

Heat is collected by tributary canals formed by the space bounded by the rafters of the roof and by a thermally insulated panel at the bottom and by the roof at the top. The tributary cannels collect and concentrate solar energy that has penetrated the roof. The heat is collected by a plurality of tributary canals, in which solar heat is absorbed. The tributary canals are positioned substantially parallel with a building roofs slope such that the higher ends of the tributary canals are in the proximity of the ridge board of the roof at which a mainstream duct collects hot air arriving through the higher ends of the tributary canals. At the end of the mainstream duct an evaporator box for housing an evaporator is placed with a fan that pulls the hot air from the tributary canals and into the mainstream duct and pushes it onto an evaporator.

Dependent claims

A heat collecting system, wherein, said heat collecting system is configured to collect and concentrate solar energy that has penetrated the roof of a building and comprises:

a plurality of tributary canals, in which solar heat is absorbed, and positioned substantially parallel with the building roof's slope such that the higher ends of said tributary canals are in the proximity of the ridge board of the roof;
a mainstream duct that collects hot air arriving through the higher ends of said tributary canals;
an evaporator box for housing a first evaporator and placed at one end of the mainstream duct;
and a fan that pulls the hot air from the tributary canals and into the mainstream duct and pushes it onto said first evaporator, and, wherein said first evaporator constitutes part of an expansive side, wherein, said expansive side containing a first refrigerant and comprises an expander which is in controlled fluid communication with said first evaporator and a first condenser, wherein, said first evaporator absorbs heat from said heat collecting system and said first evaporator acts as a power system, and, said first evaporator is configured to generate a gas-phase from a liquid-phase of said first refrigerant, resulting in an increase in pressure in said first evaporator, and said first condenser is configured to expel heat to a cooling source, and generate a liquid phase from a gas-phase of said first refrigerant, resulting in a decrease in pressure in said first condenser, wherein, the resultant difference in pressure between said first evaporator and said first condenser drives said expander, and in turn said expander provides power to a compressor, and wherein a pump is provided for delivery of liquid phase of said first refrigerant from said first condenser to said first evaporator.

A mechanical leverage system, in an air conditioning operation, comprising a compressive side and an expansive side, said compressive side containing a first refrigerant and said expansive side containing a second refrigerant, and, with respect to temperature, said first refrigerant and said second refrigerant produce different vapor pressure behaviors from one another, wherein, said compressive side comprises a compressor which is in controlled fluid communication with a first evaporator and a first condenser, wherein, said expansive side comprises an expander which is in controlled fluid communication with a second evaporator and a second condenser, wherein, said second evaporator absorbs heat that has penetrated the roof of a building and acts as a power system, and, said second evaporator is configured to generate a gas-phase from a liquid-phase of said second refrigerant, resulting in an increase in pressure in said second evaporator, and said second condenser is configured to generate a liquid phase from a gas-phase of said second refrigerant, resulting in a decrease in pressure in said second condenser, wherein, the resultant difference in pressure between said second evaporator and said second condenser drives said expander, and thus, said compressor to which said expander is connected;

and wherein said first evaporator is configured for absorbing heat from inside of the building and generating a gas-phase from a liquid-phase of said first refrigerant, and, further said compressor is configured to compress gas-phase of said first refrigerant generated in said first evaporator into said first condenser, and generate a liquid-phase from a gas-phase of said first refrigerant, wherein said first condenser is located within said second evaporator for heating said liquid phase of second refrigerant and causing said second refrigerant to boil, thereby contributing energy to said second evaporator to drive said expander;
and wherein there is a difference between the vapor pressure properties of said first refrigerant used in said compressive side and said second refrigerant used in said expansive side;
such that mechanical advantage is created between said expander and said compressor to power said compressor, based on the difference in pressure between said first evaporator and said first condenser in said expansive side as compared to the difference in pressure between said second evaporator and said second condenser in said compressive side;
such that said mechanical advantage is induced at least in part by the difference in the vapor pressure properties of said first refrigerant and said second refrigerant;
and wherein liquid phase of said first refrigerant is delivered from said first condenser to said first evaporator, and a pump is provided for delivery of liquid phase of said second refrigerant from said second condenser to said second evaporator.
