| 20100065040 | HEATING AND COOLING SYSTEM - An integrated heating and cooling system for a living space of a building connects together (a) a solar-based heating and cooling system and (b) heating and cooling systems that rely directly or indirectly on fossil fuels that are conventionally used in buildings. The system operates the solar-based heating and cooling system preferentially to heat or cool the living space. Therefore, the system minimises the use of fossil fuels to heat and cool the living space. | 03-18-2010 |
