Background technology
Vapor-compression formula cooling cycle system is adopted in present business air conditioner field usually, and it absorbs the latent heat of vaporization when utilizing the cold-producing medium evaporation and freezes.Cold-producing medium is a working media of realizing kind of refrigeration cycle in the air-conditioning refrigeration system; The air-cooled business air conditioner compressor cooling that utilizes freon refrigeration all is to rely on the air of external environment condition to flow to dispel the heat through condenser to realize; When summer, outside air temperature was higher than 38 ℃; It is very low that the condenser radiating efficiency just becomes, and it is very low that corresponding air conditioner refrigerating efficiency also just becomes.
The direct sweat cooling technology of water is mainly used in agricultural greenhouse or industrial premises, and this refrigeration modes belongs to the constant enthalpy cooling, increases the water capacity of air in the time of cooling, and when the humidity of outside air increased to a certain degree, cool effect was just no longer obvious.Be so limited, this refrigeration modes can't get into the business air conditioner field always.
Summary of the invention
The purpose of this invention is to provide the air-cooled air-conditioning of a kind of double-refrigerant integral type; Freon vapor compression refrigeration and the direct sweat cooling of water are organically combined; When outside air temperature is not too high, utilizes water to evaporate and lower the temperature, when outside air temperature is very high; Open compressor and utilize freon circulation cooling; Utilize simultaneously the water evaporative cooling to come again, the efficiency of business air conditioner refrigeration is greatly improved, also solved the difficult problem that the direct sweat cooling of prior art water can't get into the business air conditioner field simultaneously to the heat radiation of compressor condenser.
The present invention mainly is made up 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) new wind evaporative cooling district, (II) condensation blow zones, (III) return air district, (IV) air draft evaporating area; Four zones are separated by dividing plate, wherein (I), (III) respectively with (II), (IV) is interregional that the conversion air-valve arranged.
(I) the evaporation screen pack in the new wind evaporative cooling district is placed on water tank upper, and water pump places in the water tank, connects the water distributor above the evaporation screen pack through connecting line, and water distributor is a channel form; Tank level control system is arranged on the water tank the inside, is used for controlling automatically the liquid level of water tank; Air cleaner places with (II) condensation blow zones and is communicated with wind direction valve front portion, filters new wind.
(II) pressure fan in the condensation blow zones places the bottom of casing, and realization the following of cold air served back; Evaporimeter is placed on pressure fan top and is communicated with wind direction valve position with (III) distinguishing, and guaranteeing must could get into through evaporator through the air that this air-valve is come in should the zone.
(III) the return air district is positioned at (II) condensation blow zones top, on the wallboard of outside return air inlet is set.
(IV) exhaust blower in the air draft evaporating area places the top of whole box body, and condenser is placed on (IV) district and (I) distinguishes the wind direction valve position that is communicated with, and guarantees that must pass through condenser by the air that (I) district gets into could discharge.
Adopting good effect of the present invention is to have utilized the double-refrigerant refrigeration mode, and energy consumption for cooling is low, and the Energy Efficiency Ratio of unit can improve about 30%.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Fig. 1 is a 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 among the figure.
The specific embodiment
As shown in the figure: this casing 15 is divided into four parts: (I) new wind evaporative cooling district, (II) condensation blow zones, (III) return air district, (IV) air draft evaporating area; Four zones are separated by dividing plate 14, wherein (I), (III) respectively with (II), (IV) interregional have the conversion air-valve 9.
(I) the evaporation screen pack 2 in the new wind evaporative cooling district is placed on water tank 5 tops, and the material of evaporation screen pack 2 can form the corrugated plate shape juxtaposition through special process by papery, metal or inorganic material and form, and water tank 5 materials can be processed by plastics or stainless steel; Water pump 4 places in the water tank 5, connects the water distributor 1 above the evaporation screen pack 2 through connecting line, and water distributor 1 can or be injected into channel form by the pvc pipe punching; Tank level control system 6 is arranged on the water tank the inside, is used for controlling automatically the liquid level of water tank; Air cleaner 3 places with (II) condensation blow zones and is communicated with wind direction valve 9-1 front portion, and air cleaner 3 adopts nonwoven or PE materials.
(II) pressure fan 8 in the condensation blow zones can adopt centrifugal or axial flow blower, places the bottom of casing 15, and realization the following of cold air served back; Evaporimeter 7 is placed on pressure fan 8 tops and is communicated with wind direction valve 9-4 position with (III) distinguishing, and guaranteeing must could get into through evaporator 7 through the air that this air-valve is come in should the zone.
(III) the return air district is positioned at (II) condensation blow zones top, and return air inlet 11 is set on the wallboard of outside.
(IV) exhaust blower in the air draft evaporating area 12 adopts the heat transmission axial flow blower; Place casing top; Condenser 13 is placed on (IV) district and (I) distinguishes the wind direction valve 9-3 position that is communicated with, and guarantees that must pass through condenser 13 by the air that (I) district gets into 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 through the direct evaporative cooling of evaporation screen pack after again in air cleaner 3 inlet chambers, indoor hot-air is discharged outdoor through return air inlet by exhaust blower 12; Realize cold and hot air circulation, reach the cooling purpose.Just move blower fan and water pump under this state, energy consumption for cooling is very little.
When duty two, outdoor air were in high hot high humidity, wind direction valve 9-1,9-2 closed, 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 got back to indoor after the evaporator cooling once more, and outdoor air is through after evaporating the direct evaporative cooling of screen pack; Through condenser; Carry out heat exchange with condenser, take away heat, and then discharge outdoor by exhaust blower 12.Under this duty, the condenser EAT records through experiment well below outdoor temperature, and when the condenser EAT was reduced to 25 ℃ by 40 ℃, the Energy Efficiency Ratio of unit can improve about 30%.
