It is as follows that natural cooling source air conditioning display cabinet system of the present invention runs control strategy pattern:
1) fully utilized outdoor cold source cooling+cold-storage pattern
When refrigeration duty in outside air temperature is less than Storage Requirement temperature and can eliminate cabinet, refrigeration system stops fortune
OK, fully utilized outdoor cold source maintains in-cabinet temperature, cold storage simultaneously to start cold-storage with the cold-storage device of regulation system 1.Cold
After source is purified by the air cleaner 20 of new wind porch, enter cold storage and regulation by the first outdoor fresh air pipeline 3
System 1, cold wind is divided into two-way, leads up to the valve and plenum chamber 1-2 being positioned on the first airduct 1-3, is positioned at the 3rd airduct 1-5
On valve opening, mix new wind and part return air in plenum chamber 1-2, after reaching ventilation state point, through the first air supply duct
4, after being pressurizeed by breeze fan 24, enter refrigerator display case 2, and blow out to eliminate refrigerator display case 2 from air outlet and leeward plate
Cabinet in refrigeration duty.Return air through refrigerator display case return air chamber 10, under the effect of return air fan 25, enters first from return air inlet
Return air duct 5, and from first row wind pipeline 6 discharge chamber;The valve being positioned on the second airduct 1-4 of separately leading up to enters cold preservation
Cold-storage device 1-1-1 carries out cold-storage, absorbs the blower fan through being positioned on the 4th airduct 1-6 of the high temperature air after heat and pressurizes,
By being positioned at the valve on the 4th airduct 1-6, discharge from the 5th airduct 1-7;
2) outdoor cold source cooling mode
When outdoor environment temperature has run less than Storage Requirement temperature and cold-storage.Cold wind first passes through air cleaning dress
Put process, enter cold storage and regulation system 1, after the first air supply duct 4 and breeze fan 24 pressurize, enter cold preservation old
Row cabinet 2.Return air is from return air inlet through refrigerator display case return air chamber 10, and under the effect of return air fan 25, part passes through backwind tube
Road enters in plenum chamber 1-2, and wind new with outdoor carries out mixing again and reaches ventilation state point, and remaining return air is discharged by exhaust duct
Outdoor, completes circulation;
3) outdoor cold source+cold-storage device cooling mode
When outdoor temperature is higher than Storage Requirement temperature and is less than return air temperature, outdoor cold source is utilized to be taken by cold-storage device
Cold.After outdoor cold wind is purified by the air cleaner 20 of new wind porch, enter cold by the first outdoor fresh air pipeline 3 and store
Depositing and regulation system 1, be positioned at the valve closing on the first airduct 1-3, cold wind, by the valve on the second airduct 1-4, enters cold
Hide cold-storage device, from cold preservation cold-storage device take cold after cold wind by being positioned at the valve the 6th airduct 1-8 and plenum chamber 1-2,
It is positioned at the valve opening on the 3rd airduct 1-5, in plenum chamber 1-2, mixes new wind and part return air, after reaching ventilation state point, warp
