Description
Technical field
The utility model relates to air pre-processing device field, is specially a kind of new wind individual processing system in advance.
Background technology
Require the rare metallurgical workshop that belongs to of constant temperature and humidity and pressure-fired at some; Need the box-like thermostatic and humidistatic air conditioning unit group of configuration groups; Indoor primary retirn air mixes with new wind after slightly imitate and send into behind filtration, heat exchange, secondary return air mixing, humidification, the medium air filtration indoorly, and humidification adopts electricity to wet or steam humidification.
Usually because the indoor temperature precision is higher to supply air temperature difference requirement to some extent; For example temperature fluctuation allowed band is ± 0.5 ℃; The supply air temperature difference that require this moment is 3 ~ 6 ℃, and handling the air of dew point state through the table cooling coil so will be through heat again, to satisfy the requirement of supply air temperature difference.
Existing precision air conditioner engineering common practices is: after indoor return air elder generation and outdoor new wind mix; Pass through packaged air conditioner surface cooler cooling and dehumidifying again, send into air-conditioned room again after being heated to wind pushing temperature then, the advantage of this mode is that equipment is simple; Save initial capitalization; But when shortcoming is system's operation, need heat again, cold-hot counteraction, energy consumption height.
Summary of the invention
Higher to the indoor temperature precision; In order to satisfy the requirement of supply air temperature difference, when moving, need heat again in order to overcome existing precision air conditioner engineering system; Cold-hot counteraction, the defective that energy consumption is high; The utility model aims to provide a kind of new wind individual processing system in advance, and this system can have obvious energy-saving effect satisfying under the prerequisite of supply air temperature difference.
To achieve these goals; The technical scheme that the utility model adopted is: said new wind is the individual processing system in advance; Its design feature is, comprises the fresh air heat exchanger that is communicated with first fresh wind port, and the air outlet of this fresh air heat exchanger is communicated with a new blower fan; Air outlet one side of this new blower fan is provided with air heat exchanger, and air outlet one side of said air heat exchanger is provided with pressure fan.
As the preferred version of the utility model, in order to purify air, improve air quality, be provided with filter between the air outlet of said new blower fan and the air heat exchanger.
Further; In order to monitor the temperature at the air outlet place of pressure fan in real time; Be convenient to reverse adjusting; The air outlet place of said pressure fan is provided with temperature sensor Tn, and the signal output part of this temperature sensor Tn links to each other with controller XY-1, and this controller XY-1 links to each other with the water inlet motor-driven valve of control air heat exchanger.
In order to regulate air humidity; Be provided with humidifier between the air outlet of said air heat exchanger and the pressure fan; Further; The air outlet place of said pressure fan is provided with humidity sensor φ n, and the signal output part of this humidity sensor φ n links to each other with controller XY-2, and this controller XY-2 links to each other with the water inlet motor-driven valve of control humidifier.
Said new blower fan one side is provided with second fresh wind port.
Said new blower fan one side is provided with return air inlet, and this return air inlet is communicated with said pressure fan return air inlet.
By said structure; The utility model is first through after the surface cooler preliminary treatment with air conditioner fresh air; Mix through wet wind pushing temperatures that is cooled to such as packaged air conditioners with return air, wherein, the new pretreated process of wind is seen Fig. 1 again; Empty outer air ω removes in the air to dew-point temperature 0 through new blower fan group cooling and dehumidifying and is mixed to H with return air after the redundant moisture, in packaged air conditioner, is cooled to air supply parameter S again.During the Winter heat supply operating mode, new wind can not heat.
Fig. 2 is seen in the combination of new blower fan group and packaged air conditioner functional section; Little and when stable, new wind is handled and can be adopted constant dew-point temperature control mode, temperature sensor T0 when space moisture load; Through the water inlet motor-driven valve of controller xy-3 control fresh air heat exchanger, constant new wind dew-point temperature.Room temperature sensor Tn through the water inlet motor-driven valve of controller XY-1 control combination formula heat exchanger of air conditioner, regulates wind pushing temperature.When space moisture load changed greatly, new wind can adopt and become dew-point temperature control.By the room relative humidity sensor, via controller XY-2 control fresh air heat exchanger water inlet motor-driven valve, control room relative humidity.During the heat supply operating mode, the electric control valve of the temperature sensor in the room and relative humidity sensor difference control air heat exchanger and humidifier, the humiture in control room.
When being used for comfort air conditioning system, second fresh wind port can be made the air intake of the brand-new wind operation of transition season and use.
Compared with prior art, the beneficial effect of the utility model is:
1. when new wind is handled, wet amount unnecessary in the air is removed, it is but clammy that mixing air only carries out in built-up air conditioner etc., need not to heat again, avoided the cold-hot counteraction phenomenon of air-treatment, and obvious energy-saving effect is arranged.
2. new wind individual processing, operational management is more convenient, and air quantity is controlled easily, and like variable air volume system, resh air requirement can be controlled separately.When the room needs precooling or preheating, in this period, can suspend the VMC operation, reduce the novel wind energy consumption.
3. for the large and medium-sized sky system of withering, can distinguish cooling water when having ready conditions, packaged air conditioner supplies the water of higher temperature, helps the handpiece Water Chilling Units energy-saving run.
4. when the hot humidity load in room was stablized, with the control method of constant dew-point temperature, indoor relative humidity can reach than higher precision.Control mode is simple.
Below in conjunction with accompanying drawing and embodiment the utility model is done further to set forth.
