Further, above-mentioned heat exchanger 31 is braze type heat exchangers.
In native system, new wind inherent filtration section enters AHU air-conditioning box through surface cooling section, humidifier section and air supply section after entering, native system contains new wind and adds wet model and dehumidification mode, and in the time running on dehumidification mode, the second control valve cuts out, the first control valve is opened, the 3rd circulation pump; When running on when adding wet model, the second control valve is opened, and the first control valve cuts out, and the 3rd circulating pump is opened, and the first circulating pump and the second circulating pump are for strengthening the exchange heat between native system and low-temperature receiver and thermal source.Native system adopts the hot water of handpiece Water Chilling Units condenser as medium and the thermal source of new wind humidification, and wherein core cell is humidifier section, and humidifier section adopts hot water circuit process to process new wind, and its temperature and water capacity are increased.The processing procedure of the alternative a part of AHU air-conditioning box of native system, a large amount of steam reducing for new wind humidification, also can reduce most summers and dehumidify hear rate energy more simultaneously, has huge energy-saving benefit; And can, by the adjusting of the water yield and water temperature, accurately control the water capacity of new wind, be particularly useful for the new wind processing of air humidity content upper zone.
Summer dehumidification mode: outdoor new wind parameter higher than air-conditioning system set water capacity time, automated system operation dehumidification mode in summer, concrete process is:
New wind is successively by fillter section, surface cooling section, humidifier section, air supply section, and wherein in humidifier section, the 3rd circulating pump is not opened, and wet-membrane humidifier does not carry out humidification to new wind.This stylish wind only enters dehumidification mode, by the new wind water capacity after the sensor Check processing of air-conditioning system, as exceedes setting value, the first control valve is opened greatly, strengthens the flow of cold water, improves dehumidifying effect, until water capacity levels off to setting value.
After the benefit in advance new rheumatism degree being reduced means that new wind after treatment mixes with return air, only need sensible heat to process, and need not be hot again.
Respectively as shown in Figures 2 and 3, in Fig. 2 and Fig. 3, each state point definition and supposition parameter are as following table for the dehumidification process psychrometric chart of traditional air-conditioning system and the dehumidification process psychrometric chart of native system:
Suppose under some operating modes, the AHU air-conditioning box air output 100000m3/h of original air-conditioning system, new wind ratio 30%, energy consumption that can more above-mentioned two processes is as following table:
Calculate through above simulation process, traditional dehumidification process consumes the chilled water of 727.22kw cold, then needs the steam of 77.92kw heat to carry out heat again; And native system only need consume the chilled water of 649.06kw cold, energy-saving significance is remarkable.
Add wet model winter: outdoor new wind parameter lower than air-conditioning system set water capacity time, automated system operation adds wet model winter, concrete process is:
New wind is successively by fillter section, bringing-up section, humidifier section, fan section, and wherein in humidifier section, the 3rd circulating pump is opened, and wet-membrane humidifier carries out humidification to new wind.This stylish wind enters and adds wet model, by the new wind water capacity after the sensor Check processing of air-conditioning system, as higher than setting value, by-passing valve is left greatly, reduces the flow of hot water, reduces humidification amount, until water capacity levels off to setting value; If new wind water capacity is lower than setting value, the running frequency of the 3rd circulating pump is heightened, increase quantity of circulating water, increase humidification amount.
Adopt after hot water humidification, the water capacity of new wind is consistent with the temperature of indoor setting, after mixing with return air again, directly carry out sensible heat processing and can send into air conditioning area, because traditional humidification method is the steam adopting, in this process, all can save, save the consumption of steam, energy-saving and emission-reduction meaning is huge.
Respectively as shown in Figure 4 and Figure 5, in Fig. 4 and Fig. 5, each state point definition and supposition parameter are as following table for the humidification psychrometric chart of traditional air-conditioning system and the humidification psychrometric chart of native system:
The load of tradition steam humidification process and native system humidification is as following table:
Visible according to above simulation process, the steam that traditional humidification need to consume 254.53KW heat carries out warming and humidifying; Though native system humidification needs the chilled water of 64.47kw cold, produce the load of the hot water of consumed 319.13kw, far below the steam load of traditional humidification, amount of energy saving is very large.
Be illustrated in figure 6 native system practical application schematic diagram, formed by evaporimeter 5, condenser 6, cooling tower 7, AHU air-conditioning box 9, plate-type heat-exchange gas 8, new rheumatism degree treatment system 10 and the relevant distributing system of handpiece Water Chilling Units.
Native system is in the time of dehumidifying, the chilled water of handpiece Water Chilling Units evaporimeter 5 is introduced into this new rheumatism degree treatment system 10, new wind is dehumidified, after the new wind after dehumidifying mixes with return air, temperature should be still higher than indoor setting value, and therefore in AHU air-conditioning box 9, lowering the temperature, it is indoor to send into.Now the cooling tower 7 of handpiece Water Chilling Units normally moves.
Native system is in the time of humidification, and VQ-1 valve cuts out, and VQ-2 valve is opened, and condenser 6 cooling waters of handpiece Water Chilling Units enter plate type heat exchanger 8, directly return the condenser 6 of handpiece Water Chilling Units after heat exchange, and cooling tower 7 is no longer taken on the function of heat radiation.The cooling water of handpiece Water Chilling Units condenser 6 carries out heat exchange through plate type heat exchanger 8, obtain entering this new rheumatism degree treatment system 10 after heat, by wet-membrane humidifier, new wind is carried out to humidification, after the new wind after humidification mixes with return air, enter AHU air-conditioning box 9 and carry out sending into after sensible heat processing indoor.
Be combined with evaporimeter, the condenser of original AHU air-conditioning box and handpiece Water Chilling Units by native system, can accomplish that the humiture of new wind is independently controlled, reduce the new wind of traditional air-conditioning system and process energy consumption, energy-saving and emission-reduction significant.And the parts that native system adopts are all matured product, stable, reliable for effect, there is very huge general dissemination.
