Abstract
Abstract:
This invention relates to a microwave heating and air conditioning apparatus. The apparatus comprises of a magnetron as the source of microwave energy directed into the pressure vessel to vaporize the volatile mixture out of the non-azeotropic water solution. The two constituents of the solution are separated within the pressure vessel by distillation to direct the vaporized volatile into an ejector while diverting the water through an auxiliary heat exchanger into the evaporator canister. The ejector is provided with a De-Laval type nozzle to convert the heat energy into high velocity kinetic energy. Within the ejector, the high velocity jet stream is directed through a venturi to apply a vacuum at the evaporator canister, causing the fluid contained within it to cool. In addition to the auxiliary heat exchanger, the apparatus is provided with two main heat exchangers, one to cool and condense the exhaust from the ejector forming the main heating coil, and a second coil to circulate the cold water contained within the evaporator, forming the cooling coil. In the heating mode of operation, the exhaust from the ejector is circulated through the heat exchanger located within the plenum of a forced air heating system. A dual heating and air conditioning effect is achieved by exchanging the contents of the two heat exchangers through a two position 17-port spool valve.

U.~. Patent 4,178,494 i~sued to Frank P. Bottalico and Frank P. ~ottalico Jr. on December 11, 1979 di~closes an arrangement in which water i~ employed as the microwave ab~orbing material in a jacket surrounding the plenum of a forced air heating system, and heat exchange tubes com~unicating with the water jacket extend across the plenum for heating air passing therethrough. This arrangement lacks the efficiency which may be obtained from a ~imple electric re~istance isystem.
As can be seen from the above, past attempt~ at uti1izing microwave energy for heating purpo~es have not been ~ucces~ful at improving the efficiency over the isimple Ploctrical resistance element system.
Furthermore, no system exi~ts which provide both heating and air conditioning utili7.ing the microwave energy.
It i~ therefore the object of the present invention to provide a compact and efficient ~y~tem for both heating-and air conditioning utilizing microwave energy.

According to one aspect of the invention, working as a heater, a non-azeotropic water solution ~uch as a mixture of 2/3 acetone and 1/3 water by waight, is atomized through a spray nozzle into the pres~ure vessel where the volatile mixture within the ~olution i~ vaporized with microwava radiation. The two constituent~ of the ~olution are ~parated within the preYsure ves~el by di~tillation to direct the vaporized , : . ,, ~ , volatile into an ejector while diverting the liquid product throuyh an auxiliary heat exchanger into the evaporator canister. The ejector i9 provided with De-Laval type nozzle to convert the heat energy into high velocity kinetic energy. Within the ejector, the high velocity jet ~tream i~ directed through a venturi to generate a vacuum at the evaporator cani~ter, cau~ing the water contained within the cani~ter to cool. The contents of the canister i8 circulated through a heat exchanger located underground, within the water table to absorb heat. The warmer liquid i~

Claims (4)
1. An apparatus for heating and air conditioning utilizing microwave energy, comprising:
a pressure vessel equipped with internal wave guides, a transparent window to microwave energy, a port to receive the magnetron, an atomizer to break-up the supply of solution into fine droplets facilitating the quick and efficient vaporization of the volatile out of the water solution, an evaporator canister equipped with an internal float operated demand valve for topping-up the contents of the evaporator, two ports located one at the bottom of the canister and another at the top of the canister equipped with a shower nozzle for circulation of the contents, an ejector equipped with a De-Laval type nozzle to receive the vaporized volatile and direct it to the venturi as an integral component of the ejector, and a vacuum port at the leading edge of the venturi connoted to the evaporator canister, a primary heat exchanger located within the plenum of a forced air system which in the heating mode, to receive and condense the exhaust vapors from the ejector returning the condensate back to the pressure vessel through a small positive displacement pump, having transferred the heat contents from the microwave energy and from the evaporator in the form of saturated vapor to the circulating forced air system, or in the cooling mode to receive the cold liquid contents of the evaporator thus absorbing the heat from the circulating forced air system, a by-pass from the return side of the heat exchanger to the vacuum port of the ejector to provide a positive circulation within the heat exchanger, a second primary heat exchanger substantially buried underground or otherwise communicating to the outside environment to absorb heat during the heating mode of operations or to radiate heat to the outside environment during the cooling mode of operation, an auxiliary heat exchanger to cool the liquid products of the pressure vessel before transferring the liquid products to the evaporator canister.
