Fig. 1 is the summary pie graph as the absorption air-conditioner of one embodiment of the invention.This absorption air-conditioner, possess: the high-temp regenerator 10 of the molten lithium bromide water solution of low concentration that utilizes the combustion heat of burner 1 to heat in fin type heat exchanger 10a, to flow (below, abbreviate low concentration solution, intermediate concentration solution and highly concentrated solution according to the concentration of lithium bromide as); With make heated low concentration solution by high-temp regenerator 10, be separated into the 1st gas-liquid separator 11 of steam and intermediate concentration solution; With the steam that utilizes by high-temperature separator 11, heat the low-temperature regenerator 20 of the intermediate concentration solution that in fin type heat exchanger 20a, flows once again; With make heated intermediate concentration solution by low-temperature regenerator 20, be separated into the 2nd gas-liquid separator 21 of steam and highly concentrated solution; With will be by the condenser 30 of the steam cooling liquid of the 2nd gas-liquid separator 21; With the double pipe portion 40 that makes evaporimeter and absorber formation one.
In addition, though diagram is not come out, possess: the fan of condenser 30 and 40 air-supplies of double pipe portion.
High-temp regenerator 10 and low-temperature regenerator 20 use respectively in the transient heating mode, and the lithium bromide water solution of fin type heat exchanger 10a, 20a is flow through in heating; Compare with the boiler mode, because can reduce the amount of required lithium bromide water solution, the thermal efficiency during heated solution is good, and the start-up time of running beginning is fast.
Condenser 30 is that inner face is all formed the cylindrical duct of the ditch of direction in length and breadth, and most roots erectly are set, and forms at its outer setting fin.Ditch by inner face increases the surface area in the condenser 30, utilizes the wind of being sent here by fan, and steam is cooled off expeditiously.
In the bottom surface of drip pan 44, as shown in Figure 3, most dispense orifice 44a of perforation bottom surface dispose fifty-fifty along the periphery of cold water pipe 41.This dispense orifice 44a, its pore size is in the water yield after a little while, because the surface tension of water itself and the degree that can not gone out by orifice flow; Water level in drip pan 44 uprises, and utilizes its hydraulic pressure and hydraulic pressure is gone out, and therefore, can make the water yield that is spilt out by dispense orifice 44a roughly stable, and water is flowed out equably by whole dispense orifice 44a.Again, the part in the evaporation absorption chamber 43 of cold water pipe 41 is used in its outside and is all formed the rill pipe of the ditch of direction in length and breadth.By using the rill pipe, make that the water capacity is easily soaked into its outside, speed of fall is slack-off and easy expansion.And then want to be mounted on the outside that is connected on cold water pipe 41 being wound into spiral helicine coil 48 on its periphery.By this coil 48, the part of the water that is scattered out by dispense orifice 44a, the guiding curl flows, and can effectively utilize cold water pipe 41 outsides and can make that to arrive the required time of bottom longer, makes to scatter the water that comes out and positively evaporate.
Similarly,, the solution tray 46 of ring-type is set also, at an upper portion thereof, the highly concentrated solution of separating in the 2nd gas-liquid separator 21 is set, drop in the solution spreading nozzle 47 on the solution tray 46 at outer tube 42 inner faces of evaporation absorption chamber 43.In the bottom surface of solution tray 46,, most dispense orifice 46a that connect the bottom surface are set fifty-fifty along the inner face of outer tube 42 again.Again, by means such as sandblast processing, with the inner surface roughening of outer tube 42.Utilize this kind to make shaggy means, solution is soaked into easily and speed of fall slack-off, and easily expansion.And the net 49 contact outer tubes 42 inner face ground that utilization will be rolled into drum insert, and can make the high concentration expansion toward about easily of distribution, and guarantor's fluidity is improved.
By evaporation absorption chamber 43 toward the solution circulation line 50 of high-temp regenerator 10 in, setting: make low concentration solution be circulated to the circulating pump 51 of high-temp regenerator 10, the high-temperature heat exchanger 53 that is used for and makes the low temperature heat exchanger 52 of heat exchange and be used for and do heat exchange by the highly concentrated solution that the 2nd gas-liquid separator 21 is sent here by the intermediate concentration solution that the 1st gas-liquid separator 11 is sent here.
In the 1st gas-liquid separator 11 and the 2nd gas-liquid separator 21, overflow pipe 60,70 is set respectively.Be connected to solution circulation line 50.In overflow pipe 60,70, be provided with respectively, the solution temperature in each gas-liquid separator 11,21 closes the heat control valve (HCV) 61,71 of closed channel when set point of temperature is above.
Then, action about this absorption air-conditioner is described.If utilize the combustion heat of burner 1 to heat the low concentration solution that in the fin type heat exchanger 10a of high-temp regenerator 10, flows, then in the 1st separator 11, be separated into steam and intermediate concentration solution.Intermediate concentration solution after the separation after the reduction temperature, is supplied to low-temperature regenerator 20 in high-temperature heat exchanger 53, in in fin type heat exchanger 20a, flowing, heated once again by steam, in the 2nd separator 21, be separated into steam and highly concentrated solution by the 1st separator 11.Highly concentrated solution after the decline temperature, is dropped on the solution tray 46 by solution spreading nozzle 47 in low temperature heat exchanger 52, then by most dispense orifice 46a that are arranged on the solution tray 46, along the inner face distribution of outer tube 42.The highly concentrated solution that scatters utilizes net 49 and to extend to inner face all.
Again, steam is in condenser 30, and being cooled by the air-supply of not shown fan condenses into water; With the water that condenses at low-temperature regenerator 20, together drop on the drip pan 44 by water spreading nozzle 45.Then, if water accumulates in the drip pan 44, then water is forced out by most dispense orifice 44a, and on average is dispersed on the circumference of cold water pipe 41.The water that is scattered out flows down toward the below, and utilizes coil 48 with its part guiding curl.At this moment, water generation convection current is because the contact of all water is on cold water pipe 41, so conductivity of heat improves.So, water flows on the whole outer surface of cold water pipe 41, and near the past expansion by the rill pipe, so can effectively utilize whole outer surfaces.
By evaporation of water, capture the heat that is equivalent to heat of vaporization from the recirculated water that cold water pipe 41, flows, make the recirculated water cooling.Then, in indoor set, the recirculated water by circulation in cold water pipe 41 carries out cold air operation.Again, the steam after the evaporation is absorbed by the highly concentrated solution of outer tube 42 inner faces immediately.At this moment, at the inner face of outer tube 42,, utilize the air-supply of not shown fan and be cooled though highly concentrated solution take place to absorb heat.Highly concentrated solution becomes low concentration solution after absorbing steam, is sent to low temperature heat exchanger 52, high-temperature heat exchanger 53 by circulating pump 51, after the raising temperature, delivers to heating in the high-temp regenerator 10 again.
