摘要:
A dehumidifier works in conjunction with a vehicle air conditioner to reduce both condensation and cooling load on the evaporator. A unique desiccant wheel design incorporates end plates separated by desiccant tubes that allow a cooling cross flow to be sent through and between the wheel end plates, over the outside of, but sealed from the inside of, the tubes. As outside air passes through the inside half of the tubes and is dried, the released latent heat of vaporization is picked up by the cooling cross flow, which is pre heated. It continues on across the wheel, where it is turned around, heated farther by engine waste heat, and then sent through the inside of the other half of the tubes to regenerate the desiccant.

A method for heating ambient air for a passenger compartment of a motor vehicle is disclosed herein. The method includes the step of positioning a first heat exchanger proximate to a passenger compartment of a vehicle. The method also includes the step of passing ambient air for the passenger compartment through a first heat exchanger. The method also includes the step of concurrently directing distinct flows of engine coolant and steam to the first heat exchanger to heat the ambient air.

A heater core includes an inlet tank, a return tank, and an outlet tank. A plurality of parallel inlet flow tubes extend from the inlet tank to the return tank. A plurality of outlet flow tubes extend parallel to the inlet flow tubes between the return tank and the outlet tank. Corrugated cooling fins are disposed between adjacent inlet and outlet flow tubes. A perforated inlet baffle plate is disposed angularly within the inlet tank. The inlet baffle plate has a calculated angular orientation, length, and spacing within the inlet tank. An unperforated return baffle plate is disposed in the return tank. The return baffle plate has a calculated length and spacing within the return tank. The inlet baffle plate and return baffle plate provide uniform coolant flow through the plurality of inlet and outlet flow tubes.

A cylindrical stainless steel housing includes an exhaust inlet collar and exhaust outlet collar allowing exhaust gas to travel therethrough at a mean flow velocity in accordance with a velocity formula. A plurality of stainless steel tubes extend through the housing from a steam inlet manifold to a steam outlet manifold. A number and size of the tubes is determined by formulas and dependent on an Euler number, a Reynolds number, a number of transfer units, a Prandtl number, a porosity factor and a system efficiency. The tubes may comprise an S-shape or a U-shape. The tube walls have a thickness determined according to wall thickness formulas and the walls include a plurality of cavities on an interior surface of each tube wall. The cavities may comprise a conical or semi-spherical shape and have a diameter determined according to formulas.

Disclosed is a system providing practical power generation from heat energy input from a low grade source, such as solar energy. In a modified Rankine cycle, increased energy is extracted via the turbine by letting the working fluid drop to a lower pressure. Phase change of the low pressure working fluid is accomplished using enhanced condensation. Condensation is enhanced by use of an evaporative cooler. To enable continued operation when solar exposure is attenuated, a supplemental heater is included to heat the working fluid.

An evaporative cooler assembly includes a plurality of tubes extending from a refrigerant tank in a spaced relationship to one another with each tube defining a wet air passage. Each pair of adjacent tubes defines a dry air passage extending transversely to the tubes. Each tube includes a plurality of orifices each in fluid communication with the corresponding wet air passage and the adjacent dry air passage. A pair of air ducts are disposed on the refrigerant tank with the tubes being disposed between the air ducts and the air ducts being in fluid communication with the dry air passages whereby a dry air stream flows sequentially through a portion of the dry air passages and into one of the air ducts and through another portion of the dry air passages and into the other air duct until the dry air stream flows out of a dry air outlet as conditioned air.
