Description
The utility model relates to the interior evaporating and absorbing unit of heat-exchanger rig, especially Absorption Refrigerator in a kind of central air-conditioning unit.
Conventional evaporation and adsorption arrangement for absorption refrigerating machine is made up of low pressure vessel, water as refrigerant spray thrower, evaporation and heat-exchange tube bank, water collector, lithium-bromide solution spray thrower, absorption heat-exchanging tube bundle, solution container.The water as refrigerant spray thrower connects the water as refrigerant in the condenser, and chilled water that evaporating heat-exchanging pipe is intrafascicular and air heat exchanger are connected.When Absorption Refrigerator is worked, because water boiling temperature under low pressure is very low, can reach about 3 ℃, therefore spray the evaporation and heat-exchange tube bank when going up when water as refrigerant, restrain the just evaporation tempestuously of lip-deep moisture film, absorb the heat of the interior chilled water of tube bank, a large amount of water vapours that heat absorption vaporization back produces, be absorbed device and absorb, thereby the chilled water temperature that flows through in the evaporation and heat-exchange tube bank is reduced rapidly, remaining water as refrigerant flows in the water collector.In cooling back low temperature chilled water each air heat exchanger through circulating pump is delivered to machine outside, absorb airborne heat after temperature raise, the higher chilled water heat release in circulating pump is sent the evaporation and heat-exchange tube bank again back to of temperature is lowered the temperature.Meanwhile, bromize lithium concentrated solution in the absorber sprays to absorb on the heat-exchanging tube bundle and forms liquid film, promptly absorb the water vapour that produces in the evaporimeter, and a large amount of heat transferred that water vapour in the evaporimeter brings are absorbed cooling water in the heat-exchanging tube bundles, thereby cooling water temperature is raise, and the cooling water after temperature raises is delivered to outdoor cooling tower heat release cooling through circulating pump.Circulation has again and again just reached the purpose of refrigeration.
The water as refrigerant of above-mentioned evaporation and absorption device for absorption air conditioner set and chilled water are by the tube wall heat exchange, therefore just need certain heat transfer temperature difference, the temperature difference of general chilled water outlet temperature and water as refrigerant is about 2 ℃, promptly to obtain 7 ℃ chilled water, the water as refrigerant evaporating temperature is reduced to below 5 ℃, thereby causes the reduction of heat transfer efficiency.Simultaneously this structure also needs a large amount of heat exchanger tubes, and complex structure, volume is big, cost is high.
The purpose of this utility model is to provide a kind of thermal efficiency higher, simple in structure, with low cost evaporation and adsorption arrangement for absorption refrigerating machine.
For achieving the above object, the technical solution of the utility model is: in common evaporation and adsorption arrangement for absorption refrigerating machine, removed the evaporation and heat-exchange tube bank that is used for carrying out exchange heat.This evaporating and absorbing unit is made up of low pressure vessel, water as refrigerant spray thrower, chilled water spray thrower, evaporating area, chilled water water inlet diaphragm valve, chilled water water outlet diaphragm valve, water collector, lithium-bromide solution spray thrower, absorption heat-exchanging tube bundle, solution container.Water as refrigerant spray thrower, chilled water spray thrower, evaporating area, water collector, chilled water water outlet diaphragm valve, chilled water water inlet diaphragm valve are formed evaporimeter.Lithium-bromide solution spray thrower, absorption heat-exchanging tube bundle and solution container are formed absorber.Chilled water water inlet diaphragm valve is connected the outside of low pressure vessel and with the chilled water spray thrower, and chilled water water outlet diaphragm valve is outside and be connected with the bottom of water collector at low pressure vessel.When carrying out kind of refrigeration cycle, water as refrigerant and chilled water are ejected into the evaporating area of low pressure vessel, because the shower water temperature is higher than the saturation temperature under the evaporator pressure, make part water carburation by evaporation immediately, absorb the heat of shower water self, the shower water temperature is reduced, and water vapour is absorbed device and absorbs rapidly, a large amount of heats water that is cooled is taken unit out of and is discharged outward.Mixed water at low temperature flows in the water collector of bottom, directly delivers in the air heat exchanger of air-conditioning system by diaphragm valve, circulating pump then and carries out the heat exchange circulation.
In order to enlarge evaporation surface, strengthen the boiling vaporization effect of shower water, evaporating area can be irregular space, also can be all kinds of evaporative components.
Because such scheme cancelled the evaporation and heat-exchange tube bank, water as refrigerant and chilled water are united two into one, make the water at low temperature behind the evaporative cooling directly enter air heat exchange circulation as chilled water, the thermal efficiency greatly improves.For example, the chilled water that obtain 7 ℃ only needs to keep 7 ℃ evaporating temperature and 7 ℃ saturated evaporating pressure, thereby makes the structure of absorption refrigeration unit simpler, and appearance and size is dwindled greatly, and cost reduces about 20%, and weight reduces 15-20%.Under the condition of identical chilled water leaving water temperature, cooling water temperature can improve about 3 ℃, is particularly suitable for high water temperature area.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
