Abstract:
A system is provided for capturing energy from heat expelled in an exhaust of an engine of a motor vehicle and storing the captured energy. The system comprises a generator, a condenser, an evaporator, and an absorber. The generator captures heat from the exhaust of the engine and may be configured for circulating a first solution having a solute that is vaporizable by heat captured by the generator. The condenser may be coupled to the generator for receiving vaporized solute and condensing the vaporized solute to a liquid. The evaporator may be coupled to the condenser and have an orifice between the condenser and the evaporator. The evaporator may have a first fluid passage for circulating the solute and a second fluid passage for circulating a second solution. The first and second fluid passages may be configured such that solute running through the first fluid passage is vaporizable by heat absorbed from the second solution running through the second fluid passage, thereby cooling the second solution. The absorber may be coupled to the evaporator and the generator. The absorber may be configured to return the solute to solution by mixing the solute with a solvent of the first solution supplied by the generator, and for returning the first solution to the generator to complete a cycle of the system.

Abstract:
In a heat storage system for a vehicle, when a temperature of cooling water from a vehicle engine is high, adsorbents are heated by the cooling water, so that moisture is desorbed from the adsorbents in order to store heat. When the temperature of cooling water is low, the moisture is adsorbed in the adsorbents to heat the cooling water, while refrigerant in a vapor compression refrigerator is cooled by evaporating water. Thus, adsorption heat is generated from the adsorbents, and the cooling water is heated by using the adsorption heat. Accordingly, warm-up operation of the vehicle engine is facilitated, while motive power consumed by the vapor compression refrigerator can be reduced.
Abstract:
In a cooling apparatus, air within a room is first introduced into a radiator-type adsorber (1), where moisture contained in the air is adsorbed by A-type silica gel. The resulting low-humidity air is subsequently introduced into a desorption cooler (5), where moisture is desorbed from B-type silica gel, thereby humidifying and cooling the air. The resulting low-temperature air is then used for cooling. When a cooling capacity of the cooling apparatus is lowered, air from a heat source is introduced into the radiator-type adsorber (1), where the moisture is desorbed from the A-type silica gel, thereby recovering the adsorbability thereof. The high-humidity air resulting from the desorption of the moisture is subsequently introduced into the desorption cooler (5), where the moisture contained in the air is adsorbed by the B-type silica gel, thereby recovering the desorption cooling capacity thereof.
Abstract:
A ventilation system for an absorption refrigerator having a condenser and an absorber and located in a slide-out room of a recreational vehicle. The ventilation system includes a generally vertical air passage in which the condenser and the absorber are located, a lower vent for the intake of ambient air into the air passage, an upper vent for exhausting heated air from the air passage, and an air assist system for forcing air flow through the air passage only when the temperature of the ambient air is too high for an efficient natural draft. Both the lower and upper vents are in the side wall of the slide-out room. The air assist system includes a blower positioned to promote airflow within the air passage over the condenser and the absorber, a temperature activated thermal switch positioned to sense ambient temperature and adapted to energize the blower only when the ambient temperature is above a predetermined value, and a power switch connected in series to the thermal switch to activate and deactivate the system. The power switch is preferably adapted to automatically activate and deactivate the system when the refrigerator is turned on and off respectively.
