Description
Technical field
The utility model belongs to air drying, dehumidification equipment field, particularly a kind of novel air conditioning system of multistage control.
Background technology
At present, air-conditioning unit of the prior art generally includes compressor, condenser, evaporimeter, processing blower fan, handles air channel, Dehumidifying rotary wheel assembly, humidification assembly, processing air heater, regeneration blower fan, regeneration air air channel, regenerated air heater and electric control system (containing the Temperature and Humidity Control element).Under the environment of high temperature humidity, when air passes through evaporimeter (prime), air is cooled by the evaporimeter coil pipe, air is along with the reduction of temperature, and airborne water vapour condenses gradually, and the state that reaches capacity, when the dew point of air continues to reduce, airborne water vapour just becomes condensate water and separates out, thereby airborne absolute water content is reduced, and air has been realized preliminary cool-down dehumidification process; When this part air continued processing region by Dehumidifying rotary wheel, moisture wherein was adsorbed by the moisture absorption medium in the runner, and hydrone undergoes phase transition simultaneously, and discharges latent heat, runner also because of moisture absorption certain moisture tend to saturated gradually; At this moment air becomes xeothermic air because of self moisture minimizing and latent heat release, and air has been realized further intensification dehumidification process, and air can be again by being sent by the processing blower fan after evaporimeter (back level) cooling afterwards; At regeneration zone, through behind the regenerated air heater, the saturated runner after becoming high temperature air and passing moisture absorption makes the water evaporates of having adsorbed in the runner to air, thereby has recovered the wettability power of runner earlier simultaneously; This part air becomes humid air because of the evaporation of moisture in the runner simultaneously, humid air is discharged to outdoor by the regeneration blower fan more afterwards.Under the environment of low temperature drying, air, can be realized being sent by the processing blower fan behind the further heat temperature raising via the humidifier humidification by after handling the preliminary heat temperature raising of air heater (prime) realization afterwards by handling air heater (back level).
Along with the contradiction of economic development and resource environment is sharp-pointed day by day, people also improve day by day to the energy-conservation requirement of air-conditioning equipment.With regard to the air-conditioning unit, its hot humidity load and the degree of correlation of using season and place to use big (the hot humidity load of the equipment of summer, low latitudes wants big than winter, high latitude area), correspondingly the difference between the extreme heat wet cooling condition is also big.Can the special air conditioner group generally designs according to the most unfavorable processing condition, thereby guarantee under the less situation of hot humidity load, and the validity of equipment unloading operation is to weigh whether energy-conservation key.The technical scheme of taking at present has following several: the one, and adopt multiple compressors or possess the compressor of multistage unloading form, make evaporimeter and condenser also need be divided into corresponding component simultaneously; The 2nd, adopt multistage processing air heater and regenerated air heater; But these two kinds of unloading manners can cause the frequent loading and unloading of parts when critical operating mode, for example refrigeration system and heater all adopt the unloading of 25%-50%-75%-100% level Four when the outlet air parameter request is constant, in the time of near transition load in season just is in each level, be disadvantageous service life to electric component especially compressor on the one hand, if heat load is that 26% of extreme loads just surpasses refrigeration system 25% unloading point slightly on the other hand, refrigeration system can only be in 50% load running this moment, what air process evaporimeter (prime) temperature was fallen thus is low excessively, causes needs processing air heater (back level) to provide and more adds heat to guarantee stablizing of outlet temperature.Similarly, if the wet load before the Dehumidifying rotary wheel is for extremely being defeated by 50% load running, air is through Dehumidifying rotary wheel temperature rising water capacity minimizing simultaneously thus, needing to cause humidifier to provide more moisture to guarantee the stable of outlet humidity, needing to handle air heater (back level) simultaneously provides and more adds heat to guarantee the stable of outlet temperature, and this all can increase the extra power consumption of system; The 3rd, adopt variable ratio frequency changer blower fan (reducing its operation power consumption by reducing the motor running frequency under the less situation of hot humidity load) or the parallel running of many typhoons machine, but the ventilation and the blast of blower fan also can reduce during unloading, Gu and need are guaranteed that specified ventilation is for inapplicable with the use occasion of air-out overbottom pressure.
No matter whether each functional part needs to be in running status, air this parts of all must flowing through.For example,, under the environment of high temperature humidity, air need not be through handling air heater (prime), humidifier, processing air heater (back level); Under the environment of low temperature drying, air need not pass through evaporimeter (prime), Dehumidifying rotary wheel, evaporimeter (back level); During ambient temperature and moisture weather, air need not be through handling air heater (prime), evaporimeter (prime), Dehumidifying rotary wheel, humidifier, evaporimeter (26% of back lotus just surpasses 25% unloading point of regenerated air heater slightly, and this moment, regenerated air heater can only department level), handle air heater (back grade).On the one hand, air each parts of flowing through will produce local resistance loss; On the other hand, air each parts of flowing through will be followed the deterioration by oxidation process.For evaporimeter and heater, can make its heat exchanger components surface oxidation, increase surface resistance of heat transfer and reduce its heat transfer coefficient and then influence whole heat exchange effect.For electric components such as heaters, when humid air through the out-of-date potential risk of making moist that has increased electric wiring and temperature-sensing element.For Dehumidifying rotary wheel, Dehumidifying rotary wheel assembly when the intake air dew-point temperature reaches the setup parameter requirement (Dehumidifying rotary wheel, regenerated air heater and regeneration blower fan etc.) remains static, as long as contain certain moisture (in fact surrounding air also always contains certain moisture) in the air, moisture absorption medium in the Dehumidifying rotary wheel is adsorption moisture lentamente, but because the moisture of absorption this moment can not get discharging in time, Dehumidifying rotary wheel can tend to saturated gradually, so can cause the decline of adsorption capacity and influence normal service life for a long time.
In sum, the version of air-conditioning unit employing of the prior art and control model can not be implemented in the energy conservation economic operation between the multi-state well.
