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 Cross the first air supply duct 4 and enter refrigerator display case 2, discharge from first row wind pipeline 5 from refrigerator display case 2 return air out;When When outdoor temperature is higher than return air temperature, refrigeration system is out of service, utilizes return air to take cold by cold preservation cold-storage device 1-1-1, closes Closing the air-valve 26 on the first outdoor fresh air pipeline 3 and the valve being positioned on the 5th airduct 1-7, return air is from the first return air duct 5 He Valve on 4th airduct 1-6 enters cold preservation cold-storage device 1-1-1, from cold preservation cold-storage device 1-1-1 cold wind out, by the Valve and plenum chamber 1-2 on six airduct 1-8 enter refrigerator display case 2, complete circulation;
4) refrigeration system+cold-storage device cooling mode
When the cold that cold preservation cold-storage device provides is not enough to eliminate showcase refrigeration duty, refrigeration system starts.Including two Plant operation reserve
(1) when outdoor temperature is less than return air temperature, outdoor cold source is utilized to take cold by cold preservation cold-storage device 1-1-1.Room After outer cold wind is purified by the air cleaner 20 of new wind porch, by the first outdoor fresh air pipeline 3 enter cold storage with Regulation system 1, is positioned at the valve closing on the first airduct 1-3, and cold wind enters cold preservation by the valve on the second airduct 1-4 of position and stores Device for cooling 1-1-1, from cold preservation cold-storage device 1-1-1 take cold after cold wind by being positioned at the valve the 6th airduct 1-8 and static pressure Case 1-2, is positioned at the valve opening on the 3rd airduct 1-5, mixes new wind and part return air, reach ventilation state in plenum chamber 1-2 After Dian, enter refrigerator display case 2 through the first air supply duct 4, arrange from the 5th airduct 1-7 from refrigerator display case 2 return air out Go out;
(2) when outdoor temperature is higher than return air temperature, return air is utilized to take cold by cold preservation cold-storage device 1-1-1, close chamber The valve on air-valve 26 and the 5th airduct 1-7 on outer first fresh air pipeline 3, return air is from the first return air duct 5 and is positioned at the 4th Valve on airduct 1-6 enters cold preservation cold-storage device 1-1-1, from cold preservation cold-storage device 1-1-1 cold wind out, by being positioned at the Valve and plenum chamber 1-2 on six airduct 1-8 enter refrigerator display case 2, complete circulation;
5) outdoor cold source+refrigeration system air conditioning pattern
Refrigeration duty in outdoor environment temperature is still not enough to elimination cabinet less than return air temperature, the cold of cold preservation cold-storage device When making to be finished, refrigeration system starts.After low-temperature receiver is purified by the air cleaner 20 of new wind porch, enter cold storage with Regulation 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, send through first Wind pipeline 4, after being pressurizeed by breeze fan 24, enters refrigerator display case 2, and blows out from refrigerator display case 2 air outlet and leeward plate With refrigeration duty in elimination cabinet.Return air, enters through refrigerator display case return air chamber 10 from return air inlet under the effect of return air fan 25 First return air duct 5, and from first row wind pipeline 6 discharge chamber;The regulation valve being positioned on the second airduct 1-4 of separately leading up to enters Enter cold preservation cold-storage device 1-1-1 cold-storage, absorb the air draft after heat, pressurizeed by the blower fan being positioned on the 4th airduct 1-6, pass through The valve being positioned on the 4th airduct 1-6 is discharged from the 5th airduct 1-7;
6) fully utilized refrigeration system cooling mode
When outdoor environment temperature is higher than return air temperature, in the case of the cold of cold preservation cold-storage device exhausts, refrigeration system Starting, the air-valve being positioned in first outdoor fresh air pipeline the 3, first wind pushing cavity connecting tube 7 and the first air draft chamber connecting tube 8 cuts out, Completely by refrigeration system to showcase cooling.Being provided with Open valve in refrigerator display case 2, now Open valve closes remaining Valve, return air returns to refrigerator display case return air chamber 10 from return air inlet, and return air, after vaporizer cools down, blows out from air outlet with cold But food, returns again to return air inlet, completes circulation.
