Description

Absorb booster pump formula refrigeration machine

The utility model relates to a kind of absorption booster pump formula refrigeration machine, belongs to the working medium sweat cooling equipment under low pressure that utilizes.

Known Absorption Refrigerator is power with heat energy, under the thermal source effect, the absorbent that is absorbed in the device by the steam that evaporimeter produced absorbs, absorb the water absorption that is cooled of heat and heat of solution, concentration changed after absorbent had absorbed refrigerant vapour, its regeneration of under the effect of extraneous thermal source, seething with excitement then, and cold-producing medium is able to separate from absorbent, after condensation, come back to sweat cooling in the evaporimeter, form evaporation and--absorb--separation--kind of refrigeration cycle of condensation.The parts of said method are steel part, and are bulky, and used steel consumption is big, and the thermal efficiency is low, are subjected to many restrictions of cold-producing medium and absorbent, and working medium is sought difficulty.

The purpose of this utility model be overcome the problems referred to above of prior art and provide a kind of simple in structure, manufacturing is easy to maintenance, stable, noise is low, can use that multiple harmless working medium substituted freon is beneficial to environmental protection, adapts to air-conditioning, the absorption booster pump formula refrigeration machine of freezing requirement.

The purpose of this utility model reaches by following technical measures.

The utility model include evaporimeter that cold coal water pipe is arranged in one, in the absorber and the pipeline (2,4,10,14 and 15) of heat exchanger are arranged.Heat exchanger top in the absorber is provided with condensate pipe.One by pump with spray the absorption booster pump group that booster forms and lead to through pipeline (14) and absorber, on the end of pipeline (14) in absorber spray head is housed.The pipeline (4) of one heat exchanger through having choke valve is connected with evaporimeter, is connected with absorber through pipeline (10), on the end of pipeline 4 in evaporimeter spray head is housed.Evaporimeter is connected with heat exchanger (12) in the absorber through pipeline (8), and is connected with pump (9) through pipeline (15).Pipeline (2) passes heat exchange, and its two ends are connected with absorption booster pump group with evaporimeter respectively.

Absorbing booster pump utilizes the hydraulic fluid of its high-speed jet to exchange by momentum hot, extract the rare steam of working medium and the dilute liquid of evaporimeter (7) respectively through pipeline (2) and pipeline (8), heat exchanger (12) and pipeline (15), make evaporimeter (7) keep the required vacuum of evaporation process, weak solution and rare steam mix in absorbing booster pump, are pressed into absorber after the cooling of condensate pipe in the lump.Steam in the absorber is absorbed by solution owing to the pressurized of the effect that absorbs booster pump, concentrated solution after the absorption is evaporated again owing to the pressure reduction of absorber and evaporimeter is pressed into evaporimeter through heat exchanger (1), reach the refrigeration purpose thereby take away heat, so form continuous kind of refrigeration cycle by the working medium evaporation.

The utility model compared with prior art has following advantage:

1, to have changed existing Absorption Refrigerator be the conventional method of power with heat energy to the utility model, promptly do not have traditional heater, and the operation energy is only from conventional pump, thereby simple in structure, and operation is convenient, has the change meaning in engineering circle.

2, substitute traditional compressor with absorbing the booster pump group, makes easy to maintenancely, stable, it is few to move parts, the noise of no traditional compressor.

3, can use multiple harmless working medium,, can replace the freon refrigeration machine, help environmental protection as butane, propane, ammoniacal liquor etc.

4, adaptability is strong, and adjustable range is wide: adopt different working medium, temperature can be regulated in-20 ℃～50 ℃ scopes, adapts to air-conditioning, freezing requirement, and can make the refrigeration unit that various refrigerating capacitys require easily.

The explanation of accompanying drawing drawing:

Fig. 1 is a structural representation of the present utility model.

Following the utility model will describe in detail embodiment (in conjunction with the accompanying drawings).

The utility model shown in Figure 1 include evaporimeter 7 that refrigerant water pipe 6 is arranged in one, in the absorber 17 and the pipeline (2,4,8,10,14 and 15) of heat exchanger 12 are arranged.Heat exchanger 12 tops are provided with condensate pipe 16 in the absorber 11.One by pump 9 with spray the absorption booster pump group that booster 17 forms and lead to through pipeline 14 and absorber 11, on the end of pipeline 14 in absorber 11 spray head 13 is housed.The pipeline 4 of one heat exchanger 1 through having choke valve 3 is connected with evaporimeter 7, is connected with absorber 11 through pipeline 10, on the end of pipeline 4 in evaporimeter 7 spray head 5 is housed.Evaporimeter 7 is connected with heat exchanger 12 in the absorber 11 through pipeline 8, and is connected with pump 9 through pipeline 15, and pipeline 2 passes heat exchanger 1, its two ends respectively with evaporimeter 7 with absorb the booster pump group and be connected.

Use when implementing, with ammonia--water conservancy project matter is example, in evaporimeter 7, temperature is 0 ℃, pressure is 0.05MPa, concentration is 37% ammoniacal liquor evaporation, and steam is entered after heat exchanger 1 heating by pipeline 2 and absorbs booster pump 17, and weak solution is carried through pipeline 8, heat exchanger 12 heating in absorber 11 absorb booster pump 17 after pipeline 15 enters, gas-liquid mixed and heat release in this absorbs booster pump 17, condensate pipe 16 is taken away the mixed liquor heat, and gas liquid mixture is pressurized and is delivered in the absorber 11, enter the absorber state, pressure is 0.4MPa, and temperature is 15 ℃, and concentration is 65%.Concentrated solution after the absorption through pipeline 10 and in heat exchanger 1 cooling back input evaporimeter 7 and evaporating, evaporation absorbs heat and makes that refrigerant water pipe 6 is interior reduces to 5 ℃ through chilled water, chilled water reaches the refrigeration purpose with environment generation energy exchange again.
