Description

The hot fluorine defrosting device in germplasm storehouse
Technical field
The hot fluorine defrosting device in the utility model germplasm storehouse relates to technical field of refrigeration equipment; Be particularly related to the technical field of refrigeration equipment in germplasm storehouse; Relate in particular to the technical field of germplasm storehouse refrigeration plant being implemented hot fluorine defrosting; Be specifically related to germplasm storehouse hot fluorine defrosting device technical field.
Background technology
The germplasm storehouse claims low temperature drying the storage of seeds storehouse again, is the necessary facility that safety is preserved seed; In particular, the warehouse that in the mode of low temperature drying the intrinsic quality quality of seed is carried out safe and effective storage exactly.
General ripe healthy seed is placed on after drying under the indoor natural conditions and preserves, and under this preserving type, not only the intrinsic quality of seed can't obtain good preservation, and seed germination rate can drop to below 50% behind the 1-2; So, this preserving type general preservation and among the people employings that do not had special requirement more.
For carrying out scientific research, long preservation, quality protection, quality appraise, intrinsic gene, genetic mutation, specially treated, special requirement ... the seed of various situations; use above-mentioned general banking system just dying; it must just can reach its intended purposes by means of the germplasm storehouse.Because the germplasm storehouse has it to guarantee the essential condition that needs, its topmost condition is exactly a low temperature and low humidity; With mid-term the germplasm storehouse be example, mid-term, the storehouse temperature in germplasm storehouse was about-1 ℃, relative humidity≤40%, in the germplasm storehouse, preserve the seed of 15 years even 20 years, not only every quality all can safety well preserved, and only one of germination percentage just still can reach more than 85%, seed vigor is normal.So the technical conditions of germplasm storehouse most critical are exactly low temperature and low humidity.For making the germplasm storehouse keep the technical conditions of low temperature and low humidity, must implement refrigeration and dehumidifying to the germplasm storehouse; Mid-term, long-term germplasm storehouse are as adopting freezing dehumidification technology, the refrigeration compressor of implementing the refrigeration dehumidification is in refrigeration dehumidification process, because of the evaporating temperature of its operation far below 0 ℃, and be lower than the storehouse air dew point temperature in germplasm storehouse, so, moist steam in the room, germplasm Kuku can condense on the evaporimeter of refrigeration machine and be frozen into frost layer, usually said frosting that Here it is; The frost layer of frosting will influence refrigeration dehumidification effect, because of the thermal conductivity factor of frost layer has only 2.1kJ/ (mh ℃), be one of the percentage even more than percent of metal; That is: frost layer will have a strong impact on the heat-transfer effect of the evaporimeter that is made of metal, and along with the thickening of frost layer, the air throughput of evaporimeter reduce, cause the storehouse return-air to the heat output of evaporimeter descend, the cold dehumidification amount of product of refrigeration unit reduces; When the frost layer is increased to certain thickness, the desired temperature and humidity conditions of the storehouse in germplasm storehouse can't be guaranteed, and guarantee its normal humiture requirement, the frost layer on the evaporator of refrigerator must be removed; Here it is usually said defrosting.

3, because the utility model is provided with regenerator; the effect of this regenerator is: separate Freon gas and the Freon gas the liquid mixture and the freon liquid of returning from evaporimeter; gasification freon liquid, overheated Freon gas, prevent that thereby compressor from wet stroke occurring and effectively protecting compressor; because of the coil pipe of regenerator and the freon liquid in the coil pipe are caught a cold but by conduction of heat, cooled off main solenoid valve and main expansion valve equally, thereby increase in temperature is damaged the beneficial effect of main solenoid valve and main expansion valve when having obtained to avoid because of defrosting.
4, because the utility model is provided with return air door and air supply port, this return air door and air supply port all can adopt electronic mode of splitting, the water and the water vapour that can prevent the defrost pool turn back in the storehouse, return air door and air supply port are all closed during defrosting, all adopt heat preservation steam-partition damp-proof material and electronic mode of splitting as return air door and air supply port, the utility model not only can be used for germplasm storehouse but also can be used for long-term germplasm storehouse Insulating damper and can stop defrost district heat to room, germplasm Kuku infiltration in mid-term, thereby has obtained the beneficial effect of applied range.As being applied to long-term germplasm storehouse, the storehouse temperature in long-term germplasm storehouse be that-10 ℃ ± 2 ℃, relative humidity are 30% ± 7%, uses the requirement that the utility model can reach long-term germplasm storehouse fully, can satisfy safe preservation seed and reach the expection beneficial effect in 30 years.
5, because the utility model is provided with the water seal drainpipe, thereby the frosted water that has obtained to form defrosting is discharged immediately and the beneficial effect that seals immediately with water.
6, owing to being provided with evaporimeter, the utility model safeguards case, this evaporimeter safeguards that case is an insulation trapping damp proof body structure, thereby has obtained to avoid during the defrosting that a large amount of hot humidity load of external environment is infiltrated in the case, defrosting finishes to increase refrigeration unit refrigeration dehumidification load when refrigeration unit transfers refrigeration dehumidification state to, influence the stable beneficial effect of room, germplasm Kuku humiture.
7,, thereby obtained the beneficial effect that defrosting is effective, guarantee the technical conditions of germplasm storehouse low temperature and low humidity because above each bar of the present utility model is described; Forward import evaporimeter heating and melting frost layer from inside to outside after the suitable throttling step-down of HTHP chlorodifluoromethane steam of during defrosting compressor being discharged, the suitable cooling, defrosting effect is good, water vapour and the heat safeguarding in the case to be produced at evaporimeter are few, and the water vapour that is produced during defrosting and heat can not turn back in the storehouse and guarantee the requirement of storehouse low temperature and low humidity.
8, because above each bar of the present utility model is described, thus obtained " the hot fluorine defrosting device in germplasm storehouse " new equipment and can be on various refrigeration plants the beneficial effect of wide popularization and application.
9, all can purchase and obtain owing to employed each parts of the utility model, thereby obtain to draw materials conveniently, be easy to make, beneficial effect that cost is low from market.
10, since design science of the present utility model reasonable, simple in structure understandable, be convenient to manipulate, effect stability is reliable, thereby obtained to be easy to be made low, convenient a use and the sharp beneficial effect of promoting.
