Description
Technical field
The utility model is related to refrigerate, freezing equipment refrigeration technology field, and in particular to a kind of having electronic expansion valve it is small
Type refrigeration system.
Background technology
At present, refrigerating box or household freezer use the capillary of regular length in the market, and flow is relatively fixed, and refrigerating capacity can not
It adjusts, design initial stage is generally designed by most bad working environments, although can reach cryogenic temperature, can be generated more than 1 DEG C
Temperature fluctuation, and refrigeration initial stage, different loads, different circumstance temperatures, different freezing and refrigeration temperature cannot be met to temperature plateau
It is required that.
Electric expansion valve extensive use in transducer air conditioning plays and adjusts the work that refrigeration work consumption improves comfort level
With.But the electric expansion valve applied in air-conditioning can be used open range larger, be the integer step number control by stepper motor,
Control of the air-conditioning to temperature can so be substantially met, it is impossible to meet the essence to this small-power refrigeration system of refrigerating box household freezer
Thin control.
Utility model content
The purpose of this utility model is against the above deficiency, it is proposed that it is a kind of by electronic expansion valve regulation flow, according to
The difference of refrigeration requirement constantly adjusts refrigeration work consumption, realizes the small-sized refrigerating of the having electronic expansion valve of steady control the temperature inside the box
System.
The utility model specifically adopts the following technical scheme that：
A kind of small refrigeration systems of having electronic expansion valve, including control panel and by the sequentially connected compressor of pipeline,
Condenser, electric expansion valve, capillary and evaporator, the compressor, condenser, electric expansion valve and evaporator with control
Plate electricly connects, and dehumidification mode and cooling pattern are realized in the control panel control, and under dehumidification mode, control panel control electronics is swollen
Swollen valve is in low aperture state；Under cooling pattern, control panel control electric expansion valve is in high aperture state.
Preferably, the electric expansion valve further includes stepping fine tuning pattern, and stepping fine tuning pattern is by being kept for adjacent turn
The time accounting at angle is different, makes whole flowed fluctuation.
Preferably, the control panel controls the temperature fluctuation of entire small refrigeration systems to be less than 0.2 DEG C.
Preferably, environment temperature sensor, the temperature inside the box sensor and evaporating temperature sensing are also connected on the control panel
Device.
Preferably, the length of the capillary is 1.0m~2.5m.
The utility model has the advantages that：
The throttling by normal capillary is can adjust by using electric expansion valve, this electronic expansion valve regulation refrigerant stream
Amount to the different demands of cold when meeting refrigeration initial stage, different loads, different circumstance temperature, different freezing and refrigeration temperature, and can pass through
Optimal control makes the temperature inside the box more steady, and temperature fluctuation is less than 0.2 DEG C；
The degree of superheat can be flexibly controlled by electric expansion valve, evaporating temperature can avoid refrigerating system frosting, and it is permanent to influence refrigeration
Warm control effect；
Control panel includes dehumidification mode and cooling pattern, and when aperture is relatively low, evaporating temperature reduces, the fast rapid hardening of condensed water
Knot, achievees the purpose that rapid moisture removal；When aperture is bigger than normal, evaporating temperature rise, refrigerant flow increase, the increasing of integrally cooling power
Greatly, it can be achieved that fast-refrigerating.
Description of the drawings
Fig. 1 is the structure diagram of the small refrigeration systems of having electronic expansion valve；
Fig. 2 is the electric operation control circuit figure of the small refrigeration systems of having electronic expansion valve.
Specific embodiment
Specific embodiment of the present utility model is described further in the following with reference to the drawings and specific embodiments：
As depicted in figs. 1 and 2, a kind of small refrigeration systems of having electronic expansion valve, including control panel and by pipeline according to
Compressor, condenser, electric expansion valve, capillary and the evaporator of secondary connection, the length of capillary is 1.0m~2.5m.It is described
Compressor, condenser, electric expansion valve and evaporator are electricly connected with control panel, and dehumidification mode is realized in the control panel control
And cooling pattern, under dehumidification mode, control panel control electric expansion valve is in low aperture state；Under cooling pattern, control
Plate control electric expansion valve is in high aperture state.
Electric expansion valve further includes stepping fine tuning pattern, and stepping fine tuning pattern is by keeping adjacent in special time period
The time accounting of corner is different, and whole flow is made to be fluctuated in the scope of needs, can be finely tuned by stepping, more intense adjustment aperture,
Achieve the purpose that steadily to control temperature.
Control panel controls the temperature fluctuation of entire small refrigeration systems to be less than 0.2 DEG C.
Environment temperature sensor, the temperature inside the box sensor and evaporating temperature sensor are also connected on control panel.
High temperature and high pressure gas after the compressor compresses of the small refrigeration systems of the having electronic expansion valve become by condenser
For high pressure Normal Atmospheric Temperature Liquid, after electric expansion valve and capillary-compensated, low pressure, low temperature liquid is formed, low pressure is formed by evaporator
Cryogenic gas absorbs heat, and returns compressor and is compressed.The more common refrigeration system capillary of capillary is partially short, ensures to provide most base
This throttling function, to avoid because of the excessive damage press of electronic expansion valve opening.In the stage that is initially powered up, heavy load,
Electronic expansion valve opening can be tuned up, evaporating temperature can raise, but refrigerant flow can increase, and integrally cooling power increases, can
Achieve the purpose that fast-refrigerating.
Certainly, the above description is not intended to limit the present invention, and the utility model is also not limited to the example above,
The variations, modifications, additions or substitutions that those skilled in the art are made in the essential scope of the utility model also should
Belong to the scope of protection of the utility model.
