Description

Dual-generator adsorption refrigerating system
The present invention relates to refrigeration system, further be meant adsorption refrigeration system.
Traditional adsorption refrigeration system is come out for many years.It is mainly connected to form by separate unit generator and condenser, evaporimeter, makees adsorbent with calcium chloride usually, makees cold-producing medium with ammonia.When adding heater, the cold-producing medium that adsorbent absorbed wherein discharges with the steam state form, is that liquid state enters evaporimeter through condenser condenses; Stop to add heater, then described adsorbent just absorbs the liquid refrigerant in the evaporimeter with steam state, and cold-producing medium is evaporated in steam state and the absorbed process by liquid state in the evaporimeter, and the absorbing environmental heat is realized refrigeration.Not freezing when read procedure essence is heating and freeze when stopping to heat, is the batch (-type) refrigeration.For overcoming described technological deficiency, development person once adopted the many group said apparatus and the refrigeration that makes it to hocket in same refrigeration plant, with alleviation unstable temperature problem, but did not break through the limitation that system's batch (-type) freezes yet, and refrigeration is still undesirable.
The objective of the invention is, design dual-generator adsorption refrigerating system, can achieve continuous cooling, to obtain stable cryogenic temperature, and have the characteristics of structure tube list, dependable performance, make the environmental type adsorb refrigerating device that provides practicability become possibility thus.
Technical scheme of the present invention is, described dual-generator adsorption refrigerating system comprises generator, condenser, in the surge drum and the evaporimeter of cold-producing medium liquefied ammonia are arranged, its design feature is, first, the coolant conduits of second generator is through corresponding first, second stop valve is communicated with the refrigerant inlet end of condenser, the refrigerant outlet end of condenser is communicated with the inlet of surge drum, the liquid outlet of surge drum is communicated with the inlet of evaporimeter through choke valve, and the refrigerant outlet end of evaporimeter is through the 3rd, the 4th stop valve is respectively with first, the described coolant conduits of second generator is communicated with.
The present invention is actually each the related work unit of absorbing refrigeration system that utilizes prior art, double-generator (i.e. two generators) is set on this basis and through specific connection so that it can realize that continuous cooling finishes, double-generator of the present invention is meant two (platform) generators that the duty of its absorption or desorption is separate.Below in conjunction with accompanying drawing the present invention is made and to further specify.

As shown in Figure 1, the present invention includes generator (8,9), condenser (5), in the surge drum (4) and the evaporimeter (2) of cold-producing medium liquefied ammonia are arranged, its design feature is, first, second generator (8,9) coolant conduits is through corresponding first, second stop valve (6,7) the refrigerant inlet end of same condenser (5) is communicated with, the inlet of the same surge drum of refrigerant outlet end (4) of condenser (5) is communicated with, and the liquid outlet of surge drum (4) is communicated with through the inlet of choke valve (3) with evaporimeter (2), and the refrigerant outlet end of evaporimeter (2) is through the 3rd, the 4th stop valve (10,11) respectively with first, second generator (8,9) described coolant conduits is communicated with.Described connection adopts conventional communicating pipe to realize.Described first, second generator (8,9) is meant the separate generator of its duty in two courses of work, and single generator (8) or (9) can be made up of a plurality of generator units or a generator unit.(8) or (9) can form by a plurality of generator units or a generator unit.
Operation principle of the present invention is (referring to Fig. 1), when cooling off generator (8) simultaneously when adding heater (9), open stop valve (6) (11) and close stop valve (7) (10) this moment, adsorbent in the generator (9) just discharges (promptly producing " desorption " effect) with adsorbed cold-producing medium with the steam state form, its vaporized refrigerant enters through stop valve (6) and enters surge drum (4) again after condenser (5) is condensed into liquid state, and the liquid refrigerant in this surge drum (4) is supplemented in the evaporimeter (2) through choke valve (3); Meanwhile, owing to be subjected to cooling effect, adsorbent produces suction-operated to the cold-producing medium in the system in the generator (8), promptly this generator (8) adsorbs with the form of steam state the liquid refrigerant in the evaporimeter (2) through stop valve (11), liquid refrigerant in the evaporimeter (2) is become by liquid state and absorbs a large amount of heat of surrounding environment in the process of steam state, realizes refrigeration; When " desorption " of generator (9) finished and " absorption " of generator (8) reaches capacity, then close stop valve (6) (11) and open stop valve (7) (10), add heater (8) this moment and cool off generator (9) simultaneously, then the process of refrigerastion of system is identical with above-mentioned process of refrigerastion principle, so alternately, realized the continuous cooling of system, promptly realized the peculiar kind of refrigeration cycle of compression refrigerating system---Carnot cycle, this is absorbing refrigeration system breakthrough technically.Surge drum (4) plays the effect of cold-producing medium balance in the regulating system.Described choke valve can be called heating power expansion valve again from the action principle angle, and it plays the effect of high pressure liquid refrigerant being carried out throttling step-down (refrigerant flow and the pressure of evaporimeter is sent in adjustment), and its operation principle is the conventional principles of prior art.
As known from the above, the present invention is a kind of dual-generator adsorption refrigerating system, system has realized continuous cooling, and has characteristics simple in structure, dependable performance, makes to produce the practicability adsorption refrigerating device (Green Product of no freon) with stable cryogenic temperature and become possibility.
