Heat recovery system

Abstract

This is a heating and cooling system, and method that utilizes the roof of a home or building as a solar collector. A heat barrier material is secured to the inside free edges of the roof rafters to reflect radiant heat into air flow passage ways formed between the rafters, the attic side of the roof and the heat barrier materials. A loft or upper attic floor is built in the upper portion of the attic and is also covered with the heat barrier material. The attic is divided into separate areas that are connected by a ducting system that includes a filter, an evaporator and a blower. The blower produces airflow through the filter and over the evaporator coil and into a separated portion of the attic. Airflow moves through selected formed channels between rafters, barrier material and inside roof to the blower for re-circulation. This closed loop system is usable with conventional air-to-air heat pump systems, with portions of such systems or with other well-known devices such as heat exchangers and heat engines.

What is claimed is;  
     
         1 . Any house or building having any shaped roof by creating a small air space just under the roof and moving air through this air space by at least one fan or at least one blower so this air picks up the radiant heat from the roof that IT has absorbed from the sun, moving this heated air through the conditioned space of the house or building by at least one supply air duct and return through at least one return air duct to the small air space under the roof in a close loop. Or by at least one fan or at least one blower moving this heated air through at least one evaporator coil, at least one refrigerant pumped by at least one pump so this heat may be transferred to another location to be removed or used by a heat engine.  
     
     
         2 . A house as seen in FIG. 1 having one side of the roof exposed to the sun takes advantage of standard equipment as seen in other systems by moving this hot air down opposite from normal through the air spaces between the rafters picking the heat the roof has absorbed from the sun through the boxed end eves through the air four way valve by the down stairs blower through supply ducts through the supply registers through the return register though return duct through air four way valve through attic duct through attic system to the small air space in the loft or upper attic floor, when the air in the small air space in the loft has adequate heat to heat the house or building.  
     
     
         3 . A house as seen in FIG. 2 having one side of the roof exposed to the sun moves the air in a normal manner that we can boost the temperature to heat the house or building as described in details of FIG. 2.  
     
     
         4 . A house as seen in FIG. 3 which operates the same as FIG. 2 except having two sides of the roof exposed to the sun, having a two way gate of which the gate is open to the hot side in the first part of the day and then the gate open to the other side when it be comes the hotter side.  
     
     
         5 . A house as seen FIG. 9 which operates the same as FIG. 2 except FIG. 9 has the attic system is in the loft or upper attic floor above the standard attic floor to save space in the attic.  
     
     
         6 . A house as seen in FIG. 11 witch operates the same as FIG. 9 except having two sides of the roof exposed to the sun therefore the attic system in the loft or upper attic floor has air gates the first set of gates open to the hot side in the first part of the day the second set of gates open when the other side when that side becomes the hotter side and the first set of gates closes.  
     
     
         7 . The houses or buildings claimed in claims  2 ,  3 ,  4 ,  5 , and  6  all go to heating water cycle automatically when the thermostat ceases to call for heating or cooling.  
     
     
         8 . that this water can be stored in simple insolated tanks and then used to heat using one reversible pump.  
     
     
         9 . That compressor  1 FIG. 200 may be cut of after start up if systems line  19  is feed to reversing valve inlet port.  
     
     
         10 . That FIG. 200 can be used to boost the pressure of a liquid refrigerant used by any heat recovery system using any heat source to expand said refrigerant through any evaporator to drive any heat engine exhausting to any cooled condenser, with heat engine driving a ac or dc generator, compressor ,fan, blower, pump on any other mechanical devise.  
     
     
         11 . that this system may be used by any number of houses or buildings with the evaporator coils supplying heat to one house or building or one heat engine such as a house and garage, a farm or business.  
     
     
         12 . FIG. 300 is unique in that it is a heat engine and a compressor in one hermetically seal unit. That it is both a two cylinder heat engine and a two cylinder compressor with one moving part. That the valve system robs
