The heat recovery apparatus comprises a) a gas flow passage connected at one end to a source of humid gas; b) a desiccant material provided within the gas flow passage such that the humid gas contacts the desiccant material and water vapour is adsorbed releasing latent heat of adsorption; wherein the media flow passage and gas flow passage are in heat exchanging relationship, such that when the desiccant material adsorbs water vapour from the exhaust gas the latent of the adsorption is at least partially transmitted to the medium. | 03-31-2011 |
20140191050 | External Thermostat Fan Controller - A method for efficient control of a heater ventilation fan. The method includes switching the heater ventilation fan from low speed to high speed after a brief period P1 following starting, and continuing heater ventilation fan operation for a variable period of time P2 after the heat source has stopped. The period P1 is preferably about four minutes, and the period P2 is determined by the duration of heating and is generally between two and four minutes. Operating the heater ventilation fan at high speed improves heat transfer and efficiency while the heating system is operating, increases warm air movement to the space, satisfies the thermostat set point temperature in less time, reduces heating system operation, and reduces energy use. Continuing heater ventilation fan operation after turn-off maximizes recovery of additional heat from the heat exchanger to improve overall efficiency, extend the off cycle time, and save energy. | 07-10-2014 |
20140197243 | HYDRONIC AIR HEATER - A hydronic air heater includes a frame assembly defining an enclosure, an inlet air damper formed in a wall of the enclosure and providing a means of ingress for ambient air, a closed heat transfer loop disposed within the enclosure, and a blower assembly disposed within the enclosure. The heat transfer loop includes a boiler for heating a fluid, a pump for circulating the fluid within the loop and a heating coil for receiving the heated fluid from the boiler. The blower assembly is configured to draw air into the enclosure through the inlet air damper and through the heating coil whereby heat from the fluid within the heating coil is transferred to the air. | 07-17-2014 |
20140326797 | MANAGING AIR FLOW - Enclosure assemblies for managing air flow. Such assemblies include an enclosure and at least one inclined pathway in contact with the enclosure, each pathway including a pair of side wall portions and a top wall portion that collectively extend between spaced apart openings to define an air mass. One opening having a lower boundary and the other opening having an upper boundary, with the lower boundary being at an elevation higher than that of the upper boundary, such that when a temperature differential exists within a given pathway, warmer air will be trapped in an upper portion of the air mass and above the upper boundary, thereby impeding air flow from the enclosure. | 11-06-2014 |
