Embodiment:
As shown in figure 3, this air-cooler device can be according to specific ruler since different freezing and refrigeration (vehicle) characteristic sizes is different
Very little and air current composition situation provides corresponding air-cooler partitioning scenario (two subregions, four subregions etc.) and different subregions matching air quantity etc.,
Explanation is unfolded by taking freezing-cooling storeroom flat shape is square as an example, to the course of work and principle in this.
It is opened when storage capacity is higher and when food is evenly arranged in library, and observed temperature is higher than library temperature given threshold in library
Air-cooler 1, all around four subregions belong to open mode, and the liquid refrigerant in feed flow supervisor 2 passes through the first electricity respectively
Sub- expansion valve 3, the second electric expansion valve 4, third electric expansion valve 5, the 4th electric expansion valve 6 are the steaming of the first evaporator 7, second
Device 8, third evaporator 9,10 feed flow of the 4th evaporator are sent out, liquid refrigerant throttles drop under the action of four electric expansion valves
Pressure, and the sweat cooling draw heat in four evaporators；At the same time, high-temperature gas return-air passes through return air in freezing-cooling storeroom
Four tunnels are flowed through under the action of mouth 17 and frequency conversion fan 12；Preceding road air is followed by the first air-valve 13,7 draw in cold of the first evaporator
The front side air-supply into library after amount cooling, the first air outlet 18；Right wing air is inhaled followed by the second air-valve 14, the second evaporator 8
Cooling capacity is taken to cool down, the right side air-supply into library after the second air outlet 19；Way of escape air is followed by third air-valve 15, third evaporator
9 draw the rear side air-supply into library after cooling capacity cooling, third air outlet 20；Left air steams followed by the 4th air-valve the 16, the 4th
It sends out device 10 and draws the left side air-supply into library after cooling capacity cooling, the 4th air outlet 21；Storehouse temperature is in four air outlet effect declines
After temperature reaches sets requirement, air-cooler 1 is out of service.
It is opened when storage capacity is lower in library and food arrangement is uneven, and observed temperature is higher than library temperature given threshold in library cold
Blower 1 will correspond with food product and position whether at this moment 1 four subregions of air-cooler are opened, such as only exist in library
Front side houses Partial Food, then only opens front side subregion, at this moment only the first electric expansion valve 3, the first air-valve 13, first are sent
Air port 18 is opened, other electric expansion valves, air-valve and air port belong to closed state, and the liquid refrigerant in feed flow supervisor 2 is logical
Cross the first electric expansion valve 3, for 7 feed flow of the first evaporator, liquid refrigerant throttles drop under the action of the first electric expansion valve 3
Pressure, and the sweat cooling draw heat in the first evaporator 7；At the same time, high-temperature gas return-air passes through back in freezing-cooling storeroom
Cooling capacity drop is drawn under the action of the frequency conversion fan 12 of air port 17 and frequency reducing operation followed by the first air-valve 13, the first evaporator 7
The front side air-supply into library after temperature, the first air outlet 18；Storehouse temperature cooling under the effect of the first air outlet 18 reaches sets requirement
Afterwards, air-cooler 1 is out of service.
When some evaporator needs to defrost in air-cooler 1, then corresponding electric expansion valve, air-valve and wind are closed
Mouthful, open corresponding electric heater, heating defrosting；If whole evaporators are required to defrost at this time, serious according to frosting
Degree successively defrosts to each evaporator respectively；Simultaneously for temperature fluctuation minimum in the phase library that guarantees to defrost, in defrosting process
In, the evaporator that library internal loading is not carried out defrosting operation subregion by other undertakes.
