In addition, the fluid storage be provided on the circulation canal of the refrigerant in rapid steamer 110 and the absorbing liquid in absorption machine 120 is spatially respectively arranged with the flowmeter described later 190 measuring flow.
Fig. 3 is top view rapid steamer in Fig. 2 and absorption machine being provided with heat-transfer pipe, and Fig. 4 is the stereogram that each heat-transfer pipe shown in Fig. 3 is fixed on tube sheet.
Rapid steamer 110 and absorption machine 120 are formed as to form the straight tube type of installing the beeline channel of heat-transfer pipe respectively in inside.Such rapid steamer 110 and one end of absorption machine 120 are equipped with the tube sheet 112,122 of fixing heat-transfer pipe 111,121 respectively, and the other end of rapid steamer 110 and absorption machine 120 is for closing form.
Be arranged on the first heat-transfer pipe 111 made on rapid steamer 110 and by copper pipe and be bent to ∩ form, its two ends be fixed on be provided to rapid steamer 110 one end tube sheet 112 on.Be arranged on the second heat-transfer pipe 121 made on absorption machine 110 and by copper pipe and be also bent to ∩ shape, its two ends be fixed on be provided to absorption machine 120 one end tube sheet 122 on.
The two ends of first, second heat-transfer pipe 111,121 are inserted in the fixing hole (not shown) that tube sheet 112,122 is formed respectively, fixed by tube expander expand tube again, thus make rapid steamer 110 and absorption machine 120 inner sustain there is no the state close to vacuum of pressure oscillation.
Rapid steamer 110 and absorption machine 120 inside are provided with supporting member 113,123 across spacing, this supporting member 113,123 first, second heat-transfer pipe 111,121 through support first, second heat-transfer pipe 111,121 respectively.Now, consider that the length direction of first, second heat-transfer pipe 111,121 expands, first, second heat-transfer pipe 111,121 through through holes (not shown) are preferably greater than the diameter of first, second heat-transfer pipe 111,121.
On the other hand, rapid steamer 110 and absorption machine 120 are formed as, and length to the distance at center, thus makes first, second heat-transfer pipe 111,121 expand along its length than the two ends of first, second heat-transfer pipe 111,121 of ∩ shape.
As mentioned above, rapid steamer 110 and absorption machine 120 are made into the straight pipe type that inside can form beeline channel, first, second heat-transfer pipe 111,121 is made into ∩ shape, thus by refrigerant vapor heat first, second heat-transfer pipe 111,121 time first, second heat-transfer pipe 111,121 central part under the fixing state in two ends can successfully expand along its length.First, second heat-transfer pipe 111,121 is when length direction expands, stationary state (expand tube position) between the two ends of first, second heat-transfer pipe 111,121 and each tube sheet 112,122 can not destroy, thus can make the inner sustain certain pressure of rapid steamer 110 and absorption machine 120.That is, rapid steamer 110 and absorption machine 120 inner vacuum state can not be destroyed.Therefore can prevent from reducing changes in temperature efficiency.
And, be designed to the other end of closed evaporating machine 110 and absorption machine 120, and on the tube sheet 112,122 being provided to one end, fix the two ends of first, second heat-transfer pipe 111,121 respectively, thus multi-effect can be obtained compared with being equipped with tube sheet respectively with existing rapid steamer 110 and absorption machine 120 two ends.First, tube sheet only need be provided on one end, and therefore structure is simple and save manufacturing expense.Secondly, when tube sheet to be provided on two ends and to be separately fixed on each tube sheet at heat-transfer pipe two ends, need to connect the pipeline being connected to heat-transfer pipe from the two ends of rapid steamer and absorption machine, therefore pipeline connects complicated, and in the present invention tube sheet only in the side connecting pipe of rapid steamer 110 and absorption machine 120 to heat-transfer pipe 111,121, pipeline connects uncomplicated.
Fig. 5 is the stereogram of the arrester shown in Fig. 2, and Fig. 6 is by arrester transfer refrigerant steam and prevents absorbing liquid from flowing into the schematic diagram of rapid steamer.
Arrester 130 flows into preventing portion 132 by diffusion barrier 131 and absorbing liquid and forms.Diffusion barrier 131 is arranged between rapid steamer 110 and absorption machine 120, to be separated rapid steamer 110 and absorption machine 120.
Diffusion barrier 131 is formed with the multiple transfer hole 131a for being transplanted on by the refrigerant vapor generated in rapid steamer 110 in absorption machine 120.
Absorbing liquid flows into preventing portion 132 and extends to form absorption machine 120 side in the both sides of diffusion barrier 131, flows into rapid steamer 110 for preventing the absorbing liquid of absorption machine 120.Under the state that absorbing liquid inflow preventing portion 132 and diffusion barrier 131 are integrally formed, by being used for forming the punching processing transferring hole, its part is separated rear bending and is formed with diffusion barrier.Such absorbing liquid flows into after preventing portion 132 also can be formed with diffusion barrier 131 independently and engages with diffusion barrier 131.
Absorbing liquid flows into preventing portion 132 and exports side (absorption machine side) to downward-extension from transfer hole 131a, makes it downward to change the transfer direction of the refrigerant vapor transferred by transfer hole 131a.Now, absorbing liquid flows into preventing portion 132 and covers transfer hole 131a.
By having the arrester 130 of described structure, the absorbing liquid in absorption machine 120 cannot be flowed in rapid steamer 110.That is, absorbing liquid sprays downwards in the inside upper part of absorption machine 120, and absorbing liquid and second heat-transfer pipe 121 of injection bump against.The absorbing liquid 132 bumped against with the second heat-transfer pipe 121 disperses to four directions, also disperses to diffusion barrier 131, if therefore do not have absorbing liquid to flow into preventing portion 132, the absorbing liquid of dispersion can be flowed in rapid steamer 110 by transfer hole 131a.Mix with refrigerant if absorbing liquid flows in rapid steamer 110, then the contaminated refrigerant that causes of refrigerant cannot evaporate smoothly under the pressure of hope.Described problem can be solved by being equipped with absorbing liquid inflow preventing portion 132 on arrester 130.
In addition, also form absorbing liquid while forming transfer hole 131a by punching processing and flow into preventing portion 132, therefore easily to manufacture and structure is simple, thus save manufacturing expense.
