Description
Technical field
This utility model is related to technical field of refrigeration equipment, specifically a kind of liquid low-temperature receiver machine being capable of precise control of temperature
Group.
Background technology
High-accuracy heat-producing device has strict requirements, the coolant meeting of different temperatures to for the coolant temperature that it is lowered the temperature
Cause the significantly change of its service behaviour.Growing with precision equipments such as laser instrument, the liquid low-temperature receiver lowered the temperature for it is to confession
The requirement of liquid temp precise control also more and more higher, and use the thermic load of side heat-producing device to be often real-time change, therefore
There is certain difficulty for liquid temp precise control.
Ensure that, using side more stationary temperature, existing measure mainly has three kinds：
One is that refrigeration system does not adjust, and balances refrigeration system beyond using side heat installing firing equipment additional using side
The part refrigerating capacity of load.The method advantage is refrigeration and heating is two sets of single systems it is ensured that the temperature using side is non-
Chang Hengding, that is, temperature-controlled precision is high；Shortcoming is to add extra firing equipment, causes the complexity of equipment itself, and causes
The waste of the energy.
Two is according to the low factor of height using side temperature, controls the start and stop of refrigeration system to reach using side temperature one
Change in individual scope.The method advantage is that control mode is simply easily achieved, and shortcoming is that temperature control precision is relatively low, for liquid temp
Fluctuation is larger, and frequent start-stop can cause the reduction of compressor service life.
Three is according to the refrigerating capacity adjusting refrigeration system using the change of side thermic load, more constant using side to ensure
Temperature.The practice weekly notes of the method mainly have two kinds of unloading inside regulation compressor air-discharging amount and refrigeration system：Adjust compressor
The mode of capacity mainly includes compressor variable frequency, the unloading of piston compressor cylinder body, the guiding valve unloading of helical-lobe compressor and whirlpool
Digital Scroll Technology in rotation compressor, these modes all have certain limitation in use：Frequency conversion is simultaneous in consideration electromagnetism
The special occasions of capacitive can not use, and put into higher with later maintenance cost using the initial stage of converter；Piston compressor
The unloading of cylinder body is series unloading, and temperature-controlled precision is not high；And the helical-lobe compressor refrigerating capacity of guiding valve offloading functions is had on market
Often very big, cannot use in mini system, digital scroll compressor only has the product tool that the strong big factory of indivedual strength provides
There are these functions, the product of most of producer does not possess regulating power, using having certain limitation.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of liquid low-temperature receiver being capable of precise control of temperature
Unit, can effectively solve the problem that refrigeration system to exist under thermic load situation of change and controls the not high deficiency of temperature accuracy, can be in heat
Load is on a large scale（0~100%）Under electrodeless situation of change, still ensure that high temperature-controlled precision.
The technical solution of the utility model is as follows：
A kind of liquid low-temperature receiver unit being capable of precise control of temperature, includes compressor, condenser, reservoir, vaporizer, control
Device processed, water tank, solution feed pump and heat-producing device it is characterised in that：Described compressor, condenser, reservoir and vaporizer pass through
Pipeline circulates connection successively, and described vaporizer, heat-producing device, water tank and solution feed pump circulate connection successively by pipeline, described
It is connected with electric control valve, the connecting line between described vaporizer and heat-producing device between the air vent of compressor and air entry
On temperature sensor is installed, described controller one side is electrically connected with described electric control valve, on the other hand with described temperature
Sensor electrically connects.
The described liquid low-temperature receiver unit being capable of precise control of temperature it is characterised in that：Described reservoir and vaporizer it
Between connecting line on be connected with electromagnetic valve and throttling arrangement in turn.
In the control of refrigeration system, using suitable control method, according to using between side temperature and design temperature
Difference and the keying controlling electric control valve between exhaust outlet of compressor and evaporator inlet using parameters such as side rate of temperature changes
Or unlatching size, by exhaust outlet of compressor, the higher gaseous refrigerant of temperature out is directly entered air entry for realization（By aerofluxuss
Logical）；Simultaneously this extra thermic load can motorized adjustment in real time, realize total thermic load and refrigerating capacity matched it is ensured that being had using side
There is very high temperature-controlled precision.
The beneficial effects of the utility model：
1st, this utility model exists under thermic load situation of change it is achieved that the mesh of high accuracy control temperature in refrigeration system
's.
2nd, this utility model does not need to add additional heating apparatus, realizes high accuracy control by adjusting capacity size
Temperature.
3rd, this utility model passes through to arrange electric control valve it is achieved that the real-time Electronic control of extra thermic load, finally realizes
Total thermic load and refrigerating capacity are matched it is ensured that being the confession liquid temp being provided precise control using side.
4th, this utility model passes through to arrange temperature sensor it is achieved that coolant actual temperature and industrial temperature setting value
Multilevel iudge, then by Based Intelligent Control, the open frequency of electric control valve or open degree are judged.
Brief description
Fig. 1 is this utility model structural representation.
Specific embodiment
Referring to Fig. 1, a kind of liquid low-temperature receiver unit being capable of precise control of temperature, include compressor 1, condenser 2, reservoir
