Heating system
A heating system including a thermal battery including an opening, a storage container configured to hold a first fluid therein, the opening configured to expose the first fluid to atmospheric pressure; and a fluid conductor disposed through the first fluid from an inlet point at the storage container to an outlet point at the storage container, the fluid conductor configured to receive a second fluid at a first temperature at the inlet point and to supply the second fluid at a second temperature higher than the first temperature.
1 . A heating system comprising:
(a) a first fluid conductor configured to carry a working fluid upstream of an expansion valve;
(b) an evaporator disposed in an airstream and thermally connected to said first fluid conductor by a mode of convection, wherein said mode of convection is configured to be aided by a single blower; and
(c) a second fluid conductor connecting said first fluid conductor to said evaporator, wherein the expansion valve is interposed in said second fluid conductor and the working fluid upstream of said expansion valve is configured to be received at said evaporator through said expansion valve and said second fluid conductor,
wherein said first fluid conductor and said evaporator are positioned so that convective heat transfer from said first fluid conductor to said airstream lowers a temperature of the working fluid in said first fluid conductor upstream of the expansion valve, and said evaporator subsequently absorbs at least as much heat from the airstream as was lost from the working fluid, thereby compensating for the heat loss.
2 . The heating system of claim 1 , further comprising a heat exchanger comprising an upstream fluid conductor and a downstream fluid conductor thermally coupled to said upstream fluid conductor, wherein said upstream fluid conductor is configured to be connected to an inlet port of said first fluid conductor and said downstream fluid conductor is configured to be connected to an outlet port of said evaporator and heat transfer is configured to occur from the working fluid in said upstream fluid conductor to the working fluid in said downstream fluid conductor.
3 . The heating system of claim 1 , wherein said first fluid conductor comprises a featureless outer surface.
4 . The heating system of claim 1 , wherein the working fluid is a refrigerant.
