The present invention is mainly comprised of air conditioning box body, wind direction switching valve, compressor, evaporimeter, condenser, evaporation screen pack, air cleaner, water distribution system, water tank, tank level control system, water pump, pressure fan, exhaust blower, solving the technical scheme that its problem adopts is that casing is divided into four parts: (I) Xin Feng evaporative cooling district, (II) condensation blow zones, (III) return air district, (IV) air draft evaporating area, four regions are separated by dividing plate, and wherein (I), (III) are respectively and (II), (IV) is interregional a conversion air-valve.
(I) the evaporation screen pack in Xin Feng evaporative cooling district is placed on water tank upper, and water pump is placed in water tank, by connecting line, connects the water distributor above evaporation screen pack, and water distributor is channel form; Tank level control system is arranged on water tank the inside, for automatically controlling the liquid level of water tank; Air cleaner is placed in and (II) condensation blow zones connection wind direction valve is anterior, filters new wind.
(II) pressure fan in condensation blow zones is placed in the bottom of casing, realize cold air under serve back; Evaporimeter be placed on pressure fan top and (III) district be communicated with wind direction valve position, guarantee that the air of coming in by this air-valve must just can enter this region through evaporimeter.
(III) return air district is positioned at top, (II) condensation blow zones, on the wallboard of outside, return air inlet is set.
(IV) exhaust blower in air draft evaporating area is placed in the top of whole casing, and condenser is placed on (IV) district and the wind direction valve position that (I) district is communicated with, and guarantees that the air being entered by (I) district must pass through condenser and could discharge.
Adopting good effect of the present invention is to have utilized double-refrigerant refrigeration mode, and energy consumption for cooling is low, and the Energy Efficiency Ratio of unit can improve 30% left and right.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is structural representation of the present invention;
1 water distributor, 2 evaporation screen packs, 3 air cleaners, 4 water pumps, 5 water tanks, 6 tank level control systems, 7 evaporimeters, 8 pressure fans, 9 wind direction valves, 10 compressors, 11 return air inlets, 12 exhaust blowers, 13 condensers, 14 dividing plates, 15 casings in figure.
The specific embodiment
As shown in the figure: this casing 15 is divided into four parts: (I) Xin Feng evaporative cooling district, (II) condensation blow zones, (III) return air district, (IV) air draft evaporating area, four regions are separated by dividing plate 14, and wherein (I), (III) are respectively and (II), (IV) is interregional a conversion air-valve 9.
(I) the evaporation screen pack 2 in Xin Feng evaporative cooling district is placed on water tank 5 tops, and the material of evaporation screen pack 2 can form corrugated plate shape juxtaposition through special process by papery, metal or inorganic material and form, and water tank 5 materials can be made by plastics or stainless steel; Water pump 4 is placed in water tank 5, by connecting line, connects evaporation screen pack 2 water distributor 1 above, and water distributor 1 can be punched or is injected into channel form by pvc pipe; Tank level control system 6 is arranged on water tank the inside, for automatically controlling the liquid level of water tank; Air cleaner 3 is placed in and (II) condensation blow zones connection wind direction valve 9-1 is anterior, and air cleaner 3 adopts nonwoven or PE materials.
(II) pressure fan 8 in condensation blow zones can adopt centrifugal or axial flow blower, is placed in the bottom of casing 15, realize cold air under serve back; Evaporimeter 7 be placed on pressure fan 8 tops and (III) district be communicated with wind direction valve 9-4 position, guarantee that the air of coming in by this air-valve must just can enter this region through evaporimeter 7.
(III) return air district is positioned at top, (II) condensation blow zones, and return air inlet 11 is set on the wallboard of outside.
(IV) exhaust blower in air draft evaporating area 12 adopts heat transmission axial flow blower, be placed in casing top, condenser 13 is placed on (IV) district and the wind direction valve 9-3 position that (I) district is communicated with, and guarantees that the air being entered by (I) district must pass through condenser 13 and could discharge.
During work, duty one, wind direction valve 9-1,9-2 open, 9-3,9-4 close, start pressure fan 8, water pump 4 and exhaust blower 12, outdoor air by the direct evaporative cooling of evaporation screen pack after again through air cleaner 3 enter indoor, indoor hot-air through return air inlet by exhaust blower 12 discharge chambers outside, realize cold and hot air circulation, reach cooling object.Under this state, just move blower and water pump, energy consumption for cooling is very little.
Duty two, outdoor air is when the hot high humidity of height, and wind direction valve 9-1,9-2 close, and 9-3,9-4 open, and air changes interior circulation pattern into.Start pressure fan 8, water pump 4 and exhaust blower 12, start compressor 10, room air is again got back to indoor after evaporimeter cooling, outdoor air is by evaporating after the direct evaporative cooling of screen pack, through condenser, carry out heat exchange with condenser, take away heat, and then by outside exhaust blower 12 discharge chambers.Under this duty, inlet air temperature of condenser, well below outdoor temperature, records by experiment, and when inlet air temperature of condenser is down to 25 ℃ by 40 ℃, the Energy Efficiency Ratio of unit can improve 30% left and right.
