ABSTRACT:
A heat collection system is disclosed which is capable of collecting heat from an animal husbandry enclosure (10), such as a dairy barn, and transferring the heat into a home (12). Animal husbandry enclosures, such as dairy barns, tend to have excess heat, even in winter, the excess heat normally being wasted. The heat is collected by a pair of evaporators (14, 16) located in the dairy barn (10), with the evaporators being oversized to limit the amount of cooling taking place in the barn. Fluid from the evaporators is compressed by compressors (24, 26) after which it passes through a condenser (30) from which heat may be extracted into the home (12). Pressure regulating valves (20, 34) are provided to insure that the compressors (24, 26) are not overloaded and to insure that a maximum heating effect is achieved. A thermostatically controlled fan (40) is provided to drive air across the condenser (30) so that heat is introduced into the home.
