Abstract
The invention relates to an adsorption refrigerator which comprises an evaporator (1) and an adsorber (2), wherein the evaporator (1) is communicated with the adsorber (2) and internally provided with a liquid refrigerant (3), and the adsorber (2) is internally provided with an adsorbent used for absorbing the liquid refrigerant. The operating principle of the invention is as follows: the adsorption refrigerator adopts intermittent refrigeration, when in work, the interiors of the evaporator and the adsorber are led to be in negative pressure status, negative pressure leads the liquid refrigerant in the evaporator to generate phase change so as to boil and absorb ambient heat to achieve the aim of cooling, and the adsorbent in the adsorber adsorbs the gas-state refrigerant to keep the negative pressure status, thus being capable of continuously cooling for a long time in an electroless environment.
Description
Technical field
The present invention relates to refrigerating plant, particularly refrigeration machine.
Background technology
Along with global warming, outdoor body temperature lowering product will more and more receive people's attention.The product of initiatively lowering the temperature for human body mainly contains: multiple products such as vapor recycle compressor formula, thermoelectric cooling formula.These products are all driven by real-time electricity, under the wild environment of not having electricity basically, can't long-time continuous be that human body carries out the active cooling.
Summary of the invention
Technical problem to be solved by this invention is: a kind of adsorbent refrigerator is provided, and this absorption type mini refrigerating machine can the long-time continuous refrigeration under no electrical environment.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
Adsorbent refrigerator, it comprises evaporimeter, absorber, liquid refrigerant is equipped with in evaporimeter and absorber UNICOM in the evaporimeter, the adsorbent that is used for adsorptive gaseous cold-producing medium is housed in the absorber.
In the such scheme, liquid refrigerant is an aqueous water, and adsorbent is anhydrous MgCl
2Dry powder.
In the such scheme, cylindrical skeleton is housed also in the absorber, adsorbent is filled in the cylindrical skeleton.
In the such scheme, be provided with pipeline between evaporimeter and the absorber, evaporimeter is through pipeline and absorber UNICOM, and pipeline is provided with valve.
In the such scheme, the pipeline between valve and the absorber is provided with the joint that is used to connect vavuum pump, and joint is provided with gas valve.
In the such scheme, also be provided with the vacuum meter that is used to measure vacuum in the pipeline on the pipeline between valve and the absorber.
In the such scheme, evaporimeter is for twining the resistance to compression flexible pipe of human body, and an end of resistance to compression flexible pipe seals, and the other end is through pipeline and absorber UNICOM.
Operation principle of the present invention is: adsorbent refrigerator adopts the periodic refrigeration, during work, makes in evaporimeter and the absorber to be in negative pressure state; Negative pressure makes the interior liquid refrigerant of evaporimeter undergo phase transition and seethes with excitement, and the heat around absorbing, and reaches the refrigeration purpose; Adsorbents adsorb gaseous refrigerant in the absorber; Make negative pressure state be maintained, thereby under no electrical environment, can the long-time continuous refrigeration.
The invention has the advantages that:
1, liquid refrigerant is an aqueous water, and cost is low, and cold-producing medium need not to reclaim.
2, cylindrical skeleton also is housed in the absorber, adsorbent is filled in the cylindrical skeleton, and cylindrical skeleton can increase the contact-making surface of adsorbent and gaseous refrigerant.
3, evaporimeter is through pipeline and absorber UNICOM, and pipeline is provided with valve, before the use, makes earlier to be in negative pressure state in the absorber, during use, opens valve, and refrigeration machine can be started working.
4, also be provided with on the pipeline between valve and the absorber and be used to connect vacuum pump adapter, joint is provided with gas valve, can conveniently vacuumize to absorber.
5, also be used to measure the vacuum meter of vacuum in the pipeline on the pipeline between valve and the absorber, can detect the vacuum of absorber or refrigeration machine.
6, evaporimeter is for twining the resistance to compression flexible pipe of human body, and the resistance to compression flexible pipe can be arranged on the clothes inboard, and absorber can be arranged on the clothes outside, and evaporimeter can directly be a body temperature lowering.

Among the figure: 1-evaporimeter, 2-absorber, 3-liquid refrigerant, 4-pipeline, 5-valve, 6-joint, 7-gas valve, 8-vacuum meter, 9-cylindrical skeleton, 10-metallic support net.
The specific embodiment
Adsorbent refrigerator embodiment of the present invention as shown in Figure 1, it comprises evaporimeter 1, absorber 2, evaporimeter 1 and absorber 2 UNICOMs are equipped with liquid refrigerant 3 in the evaporimeter 1, the adsorbent, the cylindrical skeleton 9 that are used for adsorptive gaseous cold-producing medium are housed in the absorber 2.
Said liquid refrigerant 3 is an aqueous water, and adsorbent is anhydrous MgCl
2Dry powder, adsorbent are filled in the cylindrical skeleton 9.
Be provided with pipeline 4 between evaporimeter 1 and the absorber 2; Evaporimeter 1 is through pipeline 4 and absorber 2 UNICOMs; Pipeline 4 is provided with valve 5; Pipeline 4 between valve 5 and the absorber 2 is provided with the joint 6 and the vacuum meter 8 that is used to measure vacuum in the pipeline 4 that is used to connect vavuum pump, and joint 6 is provided with gas valve 7.
Adsorbent refrigerator of the present invention adopts the periodic refrigeration, is subnormal ambient in the system, and vacuum requires to decide according to cryogenic temperature.
Before the use, need earlier system to be vacuumized.Concrete operation method is:
1, according to cooling time and power requirement, with the water at low temperature of packing in the evaporimeter 1 below 20 ℃;
2, valve-off 5, with vavuum pump and joint 6 UNICOMs, open gas valve 7, in 15 minutes, the pressure in the absorber 2 are evacuated to 450Pa through vavuum pump, close gas valve 7, take off vavuum pump, and preparation finishes, and adsorbent refrigerator of the present invention is for use.
