Abstract:
The invention concerns an absorption cooling system for a motor vehicle using water as coolant and an absorbent. Said system comprises a circuit designed to ensure circulation of the coolant, when the engine is stopped, from the evaporator (3) to the absorber (4) passing through the electromagnetic valve (10) through the continued operation of the evaporator pump (7) for a predetermined duration and through maintaining the electromagnetic valve (10) in open position after the engine has stopped for another predetermined duration before it is closed. The evaporator pump (7) is kept in operation upon closure of the electromagnetic valve (10) so as to allow the coolant to circulate in the circuit from the evaporator (3) to the boiler (1) passing through the exchanger (6). Said system enables, when the engine is stopped, the zones containing residual deposits of absorbent to be diluted thereby preventing crystallization of said residual deposits.
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:
An auxiliary active heating and air conditioning system which uses a fuel fired heater as an energy source for both heating and air conditioning a passenger area of a motor vehicle. The system also utilizes a single heat exchanger to supply both heated and cooled air to the passenger area. The system includes a fuel fired heater for heating heat transfer fluid and a two bed sorber cooling system. The system being operable in a heating mode and a cooling mode. In the heating mode, the heated heat transfer fluid from the fuel fired heater is directed to heat exchanger in order to heat the passenger compartment. In the cooling mode, the heat transfer fluid from the heater is alternately directed to the two sorber beds such that one sorber bed is heated while the other bed cools. The alternate heating and cooling of the sorber beds in the cooling mode causes the sorber cooling system to operate and thereby deliver cooled heat transfer fluid to the heat exchanger in the passenger area.
Abstract:
A desiccant air conditioning system (10) is provided for a passenger compartment (28) of a vehicle. Ambient air, to be eventually conditioned, passes through desiccant material maintained in a desiccant chamber (14) where it loses a portion of its moisture content while its temperature rises because of the release of the heat of vapor condensation. Subsequently, this hot, dry air is passed through a heat exchanger (20) where it is cooled down to a temperature close to the ambient. This very dry, cool air is then humidified by a humidifier (24), becoming cool, moist air, that is introduced into the passenger compartment of the vehicle. Exhaust air (30) from the passenger compartment is further humidified by a humidifier (32), so as to cool it. This cooled, humidified air is then passed through the heat exchanger (20) to cool the hot, dry incoming air. The air conditioning system may also be used in a heating mode by simply deactivating the heat exchanger (20) and the two humidifiers (24 and 32) and using the exhaust air from the passenger compartment as the source of the air (42) incoming into the desiccant chamber. The desiccant material can be regenerated by means (40), such as by passing current therethrough, to drive off absorbed water.
Abstract:
A primary air conditioning system for a vehicle has an engine driven compressor which supplies refrigerant to a cooling subsystem comprising a condenser, and expansion valve, and an evaporator. A precooling system has an absorption type system which supplies refrigerant to the cooling subsystem which it shares with the primary system. A combustion unit fueled by the vehicle fuel supplies heat to the generator of the precooling system. The precooling system is used to at least partially cool the vehicle interior before it is occupied, and the primary system is used when the engine is running.
