Description
Technical field
The utility model belongs to air conditioner technical field, relates to a kind of combined air conditioner unit, is specifically related to three grades of Evaporative Cooling Air Conditioning units that a kind of evaporative cooling combines with mechanical refrigeration.
Background technology
Evaporative Cooling Air Conditioning understands that in the application table in dryings such as Xinjiang area evaporation cooling technique is a kind of energy-saving and environmental protection, the economic type of cooling that also can improve indoor air quality.The appearance let us of the level Four combined air conditioner unit that two-stage, three grades of Evaporative Cooling Air Conditioning units and evaporative cooling combine with mechanical refrigeration seen evaporation cooling technique China account for most in the humidity area be adaptable fully.But existing two-stage or three grades of Evaporative Cooling Air Conditioning units are owing to wet cooling and constant enthalpy cooling such as can only realize, its temperature drop is limited, and can't dehumidify, can not satisfy vast in the temperature drop requirement in high humility area; And the level Four composite air conditioner system that evaporative cooling combines with mechanical refrigeration exists that floor space is big, functional section many and initial cost than problems such as height.
Summary of the invention
The purpose of this utility model provides three grades of Evaporative Cooling Air Conditioning units that a kind of evaporative cooling combines with mechanical refrigeration, both solved the problem that level Four composite air conditioner system volume is big and functional section is many, the while has also solved existing two-stage or three grades of Evaporative Cooling Air Conditioning units are applied to the problem that the temperature drop requirement can not be satisfied in middle high humility area.
The technical scheme that the utility model adopted is, three grades of Evaporative Cooling Air Conditioning units that evaporative cooling combines with mechanical refrigeration comprise housing, are disposed with dew point indirect evaporative cooling section, direct evaporative cooling section, surface-type air heat exchanging segment and pressure fan by the air intake direction in the housing, wherein
The dew point indirect evaporative cooling section is used for outdoor air is produced into new wind, inserts indoor exhaust wind winter, the new wind of preheating;
Directly the evaporative cooling section is used to filter new wind, and in the winter time as humidifier, new wind is carried out humidification;
Surface-type air heat exchanging segment is used for inserting the cold water that mechanical refrigeration is produced summer, as surface cooler, inserts hot water winter, as air heater.
The utility model combined air conditioner unit combines evaporation cooling technique with mechanical refrigeration, assembled both advantages, compares with traditional mechanical refrigeration air-conditioning unit, has tangible power savings advantages.Adopt the dew point indirect evaporative cooling section to replace tubular type indirect section of section and heat pipe indirectly in the level Four Evaporative Cooling Air Conditioning unit, temperature drop better effects if not only, the resistance reduction of unit, and reduced floor space, saved initial cost.Direct evaporative cooling section has been moved on to the front of surperficial air heat exchanging segment, not only played the effect of protection heat exchanger, can also guarantee that surface air cooler (surface cooler) coil surface is moistening, thereby coil size is reduced.
Description of drawings
Fig. 1 is the structural representation of the utility model air-conditioning unit.
Among the figure, 1. dew point indirect evaporative cooling section, 2. directly evaporative cooling section, 3. surface-type air heat exchanging segment, 4. pressure fan, 5. housing.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The structure of the utility model air-conditioning unit comprises housing 5 as shown in Figure 1, is disposed with dew point indirect evaporative cooling section 1, direct evaporative cooling section 2, surface-type air heat exchanging segment 3 and pressure fan 4 by the air intake direction in the housing 5.
Dew point indirect evaporative cooling section 1 is used for outdoor air is produced into new wind, inserts indoor exhaust wind winter as auxiliary air, the new wind of preheating;
Directly evaporative cooling section 2 is used to filter new wind, and in the winter time as humidifier, new wind is carried out humidification;
Surface-type air heat exchanging segment 3 is used for inserting the cold water that mechanical refrigeration is produced summer, as surface cooler, inserts hot water winter, as air heater.
The characteristics of the utility model air-conditioning unit are: with heat pipe indirect evaporation section and the tubular indirect evaporative section in the dew point indirect evaporative cooling section 1 replacement level Four Evaporative Cooling Air Conditioning unit, not only reduced the resistance of air-conditioning unit, make that also the structure of air-conditioning unit is compact more, saved the floor space and the initial cost of air-conditioning unit; 1 winter of dew point indirect evaporative cooling section is trickle not, but feeds indoor exhaust wind, and the outdoor air that enters the air-conditioning unit is carried out preheating, plays the effect of preheater; Direct evaporative cooling section 2 is filtered air not only, and can also use as humidifier in the winter time; Surface-type air heat exchanging segment 3 charges into the cold water of being produced by mechanical refrigeration in summer, use as surface cooler, then charges into hot water winter, uses as air heater.
First section of the utility model air-conditioning unit is dew point indirect evaporative cooling section 1, indirect section and tubular type section two indirect evaporation cooling sections indirectly of heat pipe in the level Four combined air conditioner unit have been replaced with the dew point indirect evaporative cooling section, make that the structure of air-conditioning unit is compact more, initial cost is more economized; Winter is trickle but indoor exhaust wind is come the outer new wind of preheating chamber as auxiliary air not.Second section is direct evaporative cooling section 2, dust in the new wind there is good filtration, purification effect, direct evaporative cooling section 2 is placed on the front of surface-type air heat exchanging segment 3, has played the effect (preventing its heat exchange effect of dust scale effect in the above) of protection surface-type air heat exchanging segment 3; And can guarantee that through the air after the direct evaporative cooling section 2 coil surface of surface air cooler (surface cooler) is moistening summer, thereby coil size is reduced; Then can carry out humidification to air winter.The 3rd section is surface-type air heat exchanging segment 3, adopts hot water winter, plays air preheater; Adopt cold water summer, when surface cooler is used.This arrangement form is convenient to air-conditioning system is carried out continuous control.
