Description
Technical field
The present invention relates to industrial chilling unit technical field, especially a kind of cryogenic sample censorship case.
Background technology
The sample censorship of many cold chain food and medicine, sample temperature must be controlled at 0 DEG C or subzero 18 in transportation
Below DEG C, otherwise do not reach testing requirements, influence sample detection result.The general medium and small enterprise for not possessing special Refrigerated Transport facility
When industry censorship freezes or refrigerates sample, mostly simply and economically, usually slow down cold using incubator addition ice cube temporarily and be lost in,
But if environment temperature is higher or haulage time is longer, the temperature of sample censorship process just cannot be guaranteed, and lack a kind of special
The mobile refrigerating equipment used for cryogenic sample censorship.
Refrigeration Technique has been widely applied to the every field of industrial and agricultural production and daily life.Except semiconductor refrigerating with
Outside, refrigeration machine depends on the working media of inner loop flowing and realizes process of refrigerastion.It constantly produces energy with the external world and handed over
Change, i.e. the constantly draw heat from cooled object, heat is discharged to surrounding medium.The working media that refrigeration machine uses is referred to as
Refrigeration chaste tree.A series of thermal processions that refrigerant is undergone in refrigeration systems are collectively referred to as kind of refrigeration cycle.In order to realize that refrigeration is followed
Ring, it is necessary to which consumed energy, the energy can be the energy of electric energy, heat energy, mechanical energy, solar energy and other forms.Both vapor compression
Formula refrigeration system is that compressor, condenser, throttle part, evaporator form by 4 essential parts.Liquid refrigerant is in evaporator
After the cooled object heat of middle absorption, the steam of low-temp low-pressure is vaporized into, sucked by compressor, be compressed into high pressure-temperature
Condenser is discharged into after steam, within the condenser to cooling medium (water or air) heat release, is condensed into highly pressurised liquid, through choke valve section
Flow the refrigerant for low-pressure low-temperature, be again introduced into evaporator heat absorption vaporization, reach the purpose of circularly cooling.So, refrigerant exists
In system a kind of refrigeration cycle is completed through four pervaporation, compression, condensation, throttling basic processes.
Cool Storage Technology be cold is stored in agent for storage of coldness using effective means such as various physics, chemistry, machineries, it is necessary to
When the process that again discharges the cold of storage.Cold can efficiently be stored by being produced by the technology, be met again various
Physics, this material of chemical requirements are referred to as agent for storage of coldness.Agent for storage of coldness is usually used in biochemical drug, vaccine, veterinary drug, fruit, He Hai
Fresh, food etc. and need refrigeration transportation other articles cold insulation transport.Polyvinyl alcohol-borax is common efficient agent for storage of coldness, its
Percentage of weight formula is：Polyvinyl alcohol, 3.5~4.0, borax, 0.8~1.2, surplus is water, adequately expanded poly- in water
Vinyl alcohol and borax cross-linking reaction generation body structure, then absorb a large amount of moisture content and are expanded into translucent runny gel.System
When making, first it is proportionally added into water and after polyvinyl alcohol stirs toward the reaction pot for carrying steam jacket, is heated to while stirring
50 DEG C~55 DEG C, then it is proportionally added into borax and is heated to 80 DEG C~85 DEG C while stirring, and keep 20~30 at this temperature
Minute, it is cooled to 30 DEG C~35 DEG C and is packed.
Application No. CN201520501478.2 application for a patent for invention discloses a kind of freezer cold accumulating liquid refrigeration system, should
System is made up of refrigeration machine and cold accumulating liquid refrigeration system two parts, and refrigeration machine is mainly by compressor, condenser, filter, expansion
Valve, evaporator and pressure controller composition, cold accumulating liquid refrigeration system is mainly by storage cold drop, cold accumulating liquid circulation pipe, water circulating pump, system
