In an ejector, formed in a body is a swirling space which lets a high-pressure refrigerant flowing from a refrigerant inlet port swirl and introduces the swirling high-pressure refrigerant into a depressurizing space in which the swirled high-pressure refrigerant is depressurized and expanded. A passage formation member that defines a nozzle passage and a diffuser passage is shaped to have a cross-sectional area increasing with distance from the depressurizing space. Further, a temperature sensing unit of a drive device that displaces the passage formation member is housed in the body, and the temperature sensing unit and a diaphragm have annular shapes to surround at least the axial line of the passage formation member.

Ejector with temperature-sensitive drive device

An ejector has a swirling space, a pressure reducing space, a suction passage, a pressure increasing space, a nozzle passage, a diffuser passage, a passage forming member that forms the nozzle passage and the diffuser passage, and a vibration suppressing portion that suppresses a vibration of the passage forming member. The vibration suppressing portion has (i) a first elastic member that applies a load to the passage forming member in a direction in which an area of a cross section perpendicular to the direction of the central axis of the nozzle passage and the diffuser passage decreases and (ii) a second elastic member that applies a load to the passage forming member in a direction opposite from the direction in which the first elastic member applies the load to the passage forming member.

Ejector

An adsorption module has heat medium pipes through which a fluid flows, a porous heat transferring member, and adsorbent. The porous heat transferring member is a sintered body formed by sintering a metallic material that is in a form of one of powders, particles and fibers, and has pores for allowing an adsorbed medium to pass through. The porous heat transferring member is disposed on peripheries of the heat medium pipes and bonded to outer surfaces of the heat medium pipes by sintering. The adsorbent is disposed in the pores. The porous heat transferring member further has an adsorbed medium passage for allowing the adsorbed medium to pass through. The adsorbed medium passage is located between the heat medium pipes, and extends straight and parallel to axes of the heat medium pipes.

Adsorption module and method of manufacturing the same

An adsorption heat pump is provided in which water vapor can be efficiently adsorbed and desorbed using a heat source having a lower temperature than ones heretofore in use because the pump employs an adsorbent which has a large difference in water adsorption amount in adsorption/desorption and can be regenerated (release the adsorbate) at a low temperature. The invention provides an adsorption heat pump which comprises an adsorbate, an adsorption/desorption part having an adsorbent for adsorbate adsorption/desorption, a vaporization part for adsorbate vaporization which has been connected to the adsorption/desorption part, and a condensation part for adsorbate condensation which has been connected to the adsorption/desorption part, wherein the adsorbent, when examined at 25&#xb0; C., gives a water vapor adsorption isotherm which, in the relative vapor pressure range of from 0.05 to 0.30, has a relative vapor pressure region in which a change in relative vapor pressure of 0.15 results in a change in water adsorption amount of 0.18 g/g or larger.

Adsorption heat pump and use of adsorbent as adsorbent for adsorption heat pump

A heat exchanger having an adsorbing core is advantageously applied to a refrigerating system mounted on an automotive vehicle. The adsorbing core absorbs heat from coolant and gives heat to the coolant thereby to perform heat-exchanging operation. The adsorbing core is composed of a heat exchanging member such as tubes or fins of the heat exchanger and a attracting layer connected to the surface of the heat exchanging member. A seed crystal retaining layer is firmly connected to the surface of the heat exchanging member, and the attractant crystals forming the attractant layer are grown on the seed crystals by a hydrothermal crystal growth method. Since the attracting layer is uniformly formed and firmly connected to the surface of the heat exchanging member, heat is quickly transferred between the attractant layer and the heat exchanging member.

Heat exchange having adsorbing core for use in refrigerating system

An air conditioner for an automotive vehicle having a water-cooling type internal combustion engine includes: a first refrigerator; and an adsorption type refrigerator having adsorbent. The first refrigerator controls temperature of air to be blown into a passenger compartment of the vehicle. The adsorbent generates adsorption heat when the adsorbent adsorbs the medium, and desorbs the adsorbed medium when the adsorbent is heated by coolant water in the internal combustion engine. The air to be blown into the passenger compartment is heated by the adsorption heat of the adsorbent, and is cooled by evaporation latent heat of the medium.

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.

Heat storage system for vehicle, with adsorbent

The present invention provides an adsorption-type cooling apparatus comprising first, second, third, and fourth adsorption devices filled with a coolant and contain adsorbents which adsorb evaporated coolant and desorb the adsorbed coolant during heating. Adsorption cores provide heat exchange between the adsorbents and a heat medium, and evaporation and condensation cores provide heat exchange between heating medium and the coolant. A cooling device in which heating medium cooled in the evaporation and condensation cores circulates and cools the object of cooling. A heating means supplies a high-temperature heat medium to the first-fourth adsorption devices. A cooling means supplies a low-temperature heat medium which has a temperature lower than that of the high-temperature heat medium to the first-fourth adsorption devices. Also, a switching control means is provided which switches between multiple states.

A differential in refrigerant adsorption rates of adsorbent during an adsorption process and during a desorption process is enlarged, realizing improvement in refrigeration capacity, and together therewith, the number of circulation systems for coolant fluid is reduced and the number of pumps is made smaller. A heat exchanger of a first stage evaporator and a cooler for air conditioning use are connected in series, and coolant fluid cooled by this heat exchanger is supplied to the cooler for air conditioning use. Additionally, a heat exchanger of a second stage evaporator and a radiator are connected in series, coolant fluid cooled by the radiator is further cooled by the heat exchanger, and this coolant fluid is alternately supplied to heat exchanging passages of first first stage and second stage adsorption devices and to heat exchanging passages of second first stage and second stage adsorption devices.
