Abstract: An air conditioning system moisture control method and apparatus has a housing having a heat exchanger therein for removing heat and moisture from the air. The housing has a main air inlet thereinto and a main air outlet therefrom. Moisture is added to the inlet air and some of the moisture laden air is then directed from the housing through a secondary air outlet. A secondary air inlet draws outside air into the housing between the main air inlet and the heat exchanger. The moisture laden inlet air is then cooled and has moisture removed by passage through the heat exchanger. Additional moisture is then removed in the air conditioning outlet using a desiccant material, or the like, so that dew point of the air entering the heat exchanger housing is increased to improve moisture removal in the air conditioning system.

Abstract: A method and apparatus for enhancing the evaporation and moisture removal from moisture laden products in a dryer. The invention combines the inventor's prior U.S. Pat. No. 4,719,761, with a rotating drying drum having filters at the output area, and a separate pump for allowing condensation from a chilled coil to drain off, while a desiccant formed from pads or a rotatable wheel is part of a continuous feedback loop for recycling moisture. A condenser is positioned between the desiccant and the drying drum and is used as a heat exchanger for both the air inlet to the drum and the air outlet from the drum. Additionally, the evaporator drain pipe can form an additional heat exchanger when the pipe is used in the pathway of air passing from the desiccant to the evaporator coil. The invention is useful for drying various items such as clothes, agricultural products, wood, vegetables, fruit and electric components such as wafers.

Abstract: Method and apparatus for increasing removal of moisture in a cooling system provides for a desiccant to contact and evaporate moisture into the dry feed air prior to passing the feed air over cooling coils to increase the dew point (moisture content) of the feed air. This increases the moisture removal of the cooling system. The desiccant material is loaded with moisture by absorption of moisture from the moisture saturated air leaving the cooling coils. The method includes removing the moisture by desiccant from the saturated air leaving a cooling means and delivers it to dry air entering said cooling means thus, increasing the dehumidification of the cooling means.

Abstract: An automatic freeze protection valve apparatus for solar heaters is provided with a remote sensing element, remote from the valve itself and which operates in a non-modulating fashion. The valve includes a valve housing with a remote sensor operatively connected thereto from a remote position. The remote sensor includes a bulb containing a liquid adapted to compress and expand with the temperature adjacent the bulb. A piston located in the valve body is slidable therein responsive to the expansion and contraction of the liquid in the remote sensor. A valve element located in the valve housing and attached to the piston allows movement therewith. A valve seat positioned in a water passageway allows the flow of fluid therethrough when the valve is in an open position and to cut off the flow when the valve is in a closed position.

Abstract: A water heater storage reservoir partition is shaped to provide increased thermal stratification in the tank. A generally circular partition member has a central opening therein and a wedge shape portion removed therefrom so that the circular flat partition member can be folded into a cone for attaching into a water heater tank and especially into a solar heater tank provided with solar heated water. The peripheral edge of the partition member has removed portions therefrom so that falling cooler water is allowed to pass along the tank walls through the plurality of removed portions in the edge of the water heater partition. The hot water is stratified towards the middle of the tank while cooler water passes along the walls of the tank and accumlates in the bottom of the tank. A screen may be placed in the center opening of the partition. One or more holes may be provided within the partition for the sacrifical anode or a water pipe.
