Study On Electric Field Enhanced Regeneration Of Small Solution Air Conditioning Desiccant

The solution air conditioner can regulate the indoor air humidity and reduce the air conditioning energy consumption.In addition,when the haze gradually becomes serious,the salt solution in the solution conditioning system can effectively kill the bacteria in the air and settle the dust in the air to purify the air.The dehumidification performance of the solution air conditioner is the core of the entire system operation,and the regeneration effect is the key to successful dehumidification.Therefore,it is of great engineering and theoretical significance to carry out research on the regeneration of high-pressure electrostatic fields for enhanced solution regeneration.First of all,experiments were conducted on the range of action of the high-voltage electrostatic field.The results show that the electrostatic field strength of the single-needle electrode changes little after X ? 400 mm and is also at a very low field strength value.Based on this,experimental studies were conducted on various electric field conditions such as the electrode type,voltage magnitude,and electrode distance.The experimental results showed that the regeneration rate under the action of the four-needle electrode was 2.88 times that of the wire electrode and the single-needle electrode,respectively.And 1.59 times;the electric field regeneration enhancement rate increases with voltage increase,when the voltage is 40 k V,the regeneration amount is increased to 0.938kg/h,the regeneration enhancement rate is increased to 93.23%;the electric field regeneration enhancement rate increases with the electrode distance.When the electrode distance was 500 mm,the regeneration amount was as low as 0.524 kg/h and the regeneration enhancement rate dropped sharply to 8.06%.Then the effect of solution parameters changes on the electric field strengthening effect was studied,and the energy consumption was analyzed: When the solution concentration increased to 33.6%,the regeneration enhancement rate under a 40 k V electric field drastically decreased to 9.49%.It was found that when the solution concentration was greater than 33% The effect of high voltage electric field on the regeneration of the solution is relatively weak;the regeneration effect of the applied electric field at 50°C is better than that of the 60°C without electric field,and it can be seen that the high-voltage electrostatic field strengthens the regeneration and energy saving by about 23.7 on the basis of ensuring the same regeneration effect.%.The strengthening mechanism of the electric field can be used very well in the solution dehumidification technology.The research in this paper provides some basic support for the further engineering application of small-scale solution air conditioners.
