Abstract

A frictional heating system for communicating with an air supply duct to heat and cool air in a building, including an enclosure defining an interior, two air inlets, and at least one air outlet therein communicating with the interior of the enclosure for permitting air flow therethrough. A plurality of turbines are carried on a common shaft for rotation therewith. Each of the turbines is positioned within the enclosure for drawing air into the enclosure and frictionally heating the air therein. A first conduit is in fluid communication with the air outlet, a water heater and an air conditioning system, for moving frictionally-heated air from the air outlet to one or the other of the water heater and the air conditioning system. A motor assembly including a motor is operatively connected to the common shaft and positioned outside the enclosure for driving the common shaft and turbines.

Dependent claims

A frictional heating system communicating with an air supply duct to heat and cool air in a building, comprising:

(a) an enclosure defining an interior, two air inlets, and at least one air outlet therein communicating with said interior of said enclosure for permitting air to flow therethrough;
(b) a plurality of turbines carried on a first shaft for rotation therewith, each of said turbines positioned within the enclosure for drawing air into the enclosure and frictionally heating the air therein;
(c) a plurality of turbine housings positioned within the enclosure, each of said turbine housings defining an interior in fluid communication with the air inlet for permitting air to flow into the turbine housings and the air outlet for permitting the air to flow out of the turbine housings, wherein each of said turbines is positioned within a respective one of the turbine housings for drawings air into the respective turbine housing interior and frictionally heating the air therein;
(d) a motor assembly including:
(i) a motor carried on a second shaft operatively connected to said first shaft and positioned outside the enclosure for driving the first shaft and turbines mounted thereon;
and
(ii) an intake fan mounted on the first shaft and positioned within the air supply duct for drawing ambient air therethrough;
(e) a first conduit in fluid communication with said air outlet, a water heater and an air conditioning system for moving frictionally-heated air from the air outlet to one or the other of said water heater and said air conditioning system;
and
(f) a first directional valve positioned in said first conduit for selectively moving frictionally-heated air from the air outlet to one or the other of the water heater and the air conditioning system.
