The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified
Referring to Fig. 1
Fig. 1 is existing air-conditioning unit structural representation.Its workflow is: new wind enters primarily efficient filter 4, fresh air cooler 12, new wind heater 13, the seam humidifier 14 of new blower fan group A in Fig. 1, carry out the processing of humiture, mix with return air by the mixer 11 that new wind blower fan 15 is admitted to Cycle Unit B the back, mixed mixed wind is shown cold 6 by air-supply and is lowered the temperature, and is sent into the factory building space by breeze fan 7 pressurizations by muffler 8, medium effeciency filter 9 and high efficiency particulate air filter 10 at last.
Wherein the surface cooler 12 of new blower fan group moved when temperature is higher than required value such as summer, and heater 13 moves such as winter when temperature is hanged down required value; Seam humidifier 14 is operation in the winter time generally; Because the air-supply surface cooler of the too high Cycle Unit of return air temperature 6 needs operation throughout the year; Caused the significant wastage of the energy.
Referring to Fig. 2
Fig. 2 is a structural representation of the present utility model.Its workflow is:
In the winter time, return air is through pipe heat exchanger 1 and the lower outdoor new air heat-exchange precooling of temperature, and temperature reduces relative humidity and increases; Return air enters mixer 11, is adjusted to suitable air quantity with stylish wind through roughing efficiency air filter 4 and through new wind air-valve 3, sends uniformly with return air by new wind ventilation terminal 2 and mixes, and carries out the wet exchange of heat, and temperature reduces relative humidity and increases; Mixing wind enters water spray chamber 5 and carries out the moistening and lowering temperature processing, and temperature reduces absolute humidity and increases; The such processing of process just can reach the air-supply requirement of low temperature and high relative humidity, delivers to the factory building space through surface cooler 6, breeze fan 7, muffler 8, medium effeciency filter 9 and high efficiency particulate air filter 10 again.At this moment the surface cooler 6 of blowing does not move.
In summer, return air is through pipe heat exchanger 1 and outdoor new air heat-exchange precooling, and temperature reduces relative humidity and increases; Return air enters mixer 11, is adjusted to suitable air quantity with stylish wind through roughing efficiency air filter 4 and through new wind air-valve 3, sends uniformly with return air by new wind ventilation terminal 2 and mixes, and carries out the wet exchange of heat, and temperature reduces relative humidity and increases; Mixing wind enters water spray chamber 5 and carries out the moistening and lowering temperature processing, and temperature reduces absolute humidity and increases; Mix wind and also will carry out the machinery cooling through air-supply surface cooler 6; Just can reach the requirement of low temperature and high relative humidity through such processing air-supply; Deliver to the factory building space through breeze fan 7, muffler 8, medium effeciency filter 9 and high efficiency particulate air filter 10 again.
Wherein, when new wind-warm syndrome degree was equal to or higher than return air temperature, pipe heat exchanger 1 quit work;
At major part transition season in spring and autumn, return air is through pipe heat exchanger 1 and outdoor new air heat-exchange precooling, and temperature reduces relative humidity and increases; Return air enters mixer 11, is adjusted to suitable air quantity with stylish wind through roughing efficiency air filter 4 and through new wind air-valve 3, sends uniformly with return air by new wind ventilation terminal 2 and mixes, and carries out the wet exchange of heat, and temperature reduces relative humidity and increases; Mixing wind enters water spray chamber 5 and carries out the moistening and lowering temperature processing, and temperature reduces absolute humidity and increases; The such processing of process just can reach the air-supply requirement of low temperature and high relative humidity, delivers to the factory building space through breeze fan 7, muffler 8, medium effeciency filter 9 and high efficiency particulate air filter 10 again.
The utility model air-conditioning unit adopts pipe heat exchanger 1, utilizes new wind to the return air precooling; The new wind ventilation terminal 2 that adopts in even distributing wind, can also play the effect that increases new wind air intake pressure, has increased resh air requirement, has so just saved new wind breeze fan 15; Water spray chamber 5 belongs to equal-enthalpy humidifying, air is increased the same of humidity can also reduce its temperature.
Referring to Fig. 3
Fig. 3 is new wind ventilation terminal structure chart, and when return air passed new wind ventilation terminal arm 17, circulation area reduced to make wind speed to increase, and has just produced a negative pressure at new 18 places, wind cloth air port, and so new wind air intake pressure is just strengthened relatively, and resh air requirement increases.
