Description
Technical field
Energy-conserving and environment-protective sciemtifec and technical sphere is the utility model is related to, relates more specifically to a kind of dry air curtain barrier evaporator
Frosting cold store energy saving facility.
Background technology
Freezer frosting is always the significant problem of freezer operational efficiency, and the energy consumption of freezer operation defrost occupies freezer total energy
As many as 1/3rd of consumption, for many years the straight grip of research one of industry how to go the method for the technology of molten white defrost as breakthrough,
But actually simply cure the symptoms, not the disease, therefore produced little effect so far in effect.
The energy consumption of existing freezer, significant portion are consumption in the defrost process of refrigeration system and the poorly efficient fortune of refrigeration system
OK, remainder just acts on the refrigerating of article, and the frosting of freezer evaporator is the flow field needs because cold storage locker door, when
When Ku Men opens disengaging goods, Ku Nei and the extraneous huge temperature difference (with -18 DEG C of summer storehouse temperature, exemplified by 35 DEG C of ambient temperature,
The temperature difference is up to 53 DEG C.) make to produce strong cold-hot air convection at the door of storehouse, a large amount of Hot wet air heatings enter freezer, cause freezer
Evaporator surface frosting, the exchange efficiency of evaporator declines during slight frosting, compressor fallback, evaporator during serious frosting
Interior refrigerant is unable to evaporating completely, and refrigeration system is degrading, and Ku Wen is difficult to decline, and compressor works long hours, system COP
Value declines.
At this moment have to run by defrost, refrigeration system is re-established original state, freezer can just continued normal
Operation.Because freezer is generally not provided with ventilation equipment, vapor caused by defrost is still gathered at the top of freezer and in storehouse, is changed
After frost end refrigeration system is reworked, it is gathered in the vapor at the top of freezer and comes back to evaporator surface frosting quickly,
In order that freezer can normally be run, summer typically needs defrost 6-8 times daily, so goes round and begins again, and generates freezer fortune
Capable huge energy consumption.And the defrost behavior of existing freezer technology, be intended merely to tackle freezer can normal operation and set.
Enumerate the energy distribution with the universal representational habitual configuration of existing freezer industry refrigeration system：
The freezer runs power consumption daily：
=[(compressor power consumption Ys+ air-cooler power consumption Lf+ condensers power consumption Ln) × run time H]
+ [(defrost electrical heating power consumption Hsd × defrost time Hsh × defrost number Hsc)
+ defrost heat cooling refrigeration power consumption Hsl]
Wherein：Compressor power consumption Ys=134kw/h
Air-cooler power consumption Lf=2.2kw/s
Condenser power consumption Ln=6.2kw/h
Run time H=16h
Defrost electrical heating power consumption Hsd=180kw/h
Defrost time Hsh=0.5h
Defrost number Hsh=6
Defrost heat cooling refrigeration power consumption Hsl=defrost heat ÷ refrigeration efficiency ratios
=540kw/h ÷ (280kw/h ÷ 134kw/h)
=540kw/h ÷ 2
=270kw/h
Shown with numerical value：
[(134kw/h+2.2kw/h+6.2kw/h)×16H]
+[(180kw/h×0.5×6)+270kw/h]
=[142.4kw/h × 16H]+[540kw/h+270kw/h]
=2278.4kw/h+810kw/h
=3088.4kw/h
Operate above the energy distribution situation that parameter shows the freezer；
1. the daily operation power consumption of refrigeration system is 2278.4kw/h.
2. the daily defrost power consumption of defrosting system is 810kw/h.
Configuration and the operation energy consumption for showing the more universal cold storage refrigerating system in China are calculated above, and wherein defrost is run
Energy consumption account for 1/3rd of system operation energy consumption, be calculated with 365 days 1 year, and the year defrost operation energy consumption of the freezer reaches
295650kw/h.Therefore, the defrost number of run for reducing freezer is the maximally effective means of cold storage refrigerating system energy saving in running.
Further, since the low-temperature condition of freezer, traditional heating and dehumidification and dehumidification by condensation all can not be under freezer environment just
Often work, so freezer dehumidifying is always the insoluble stubborn enemy of industry.
To sum up, this area, which still lacks one kind, to help freezer to dehumidify, and reduce frosting in freezer, and then reduce defrost time
Number, reduce the device of freezer energy consumption.
