Description
Technical field
The present invention relates to the dehumidification equipment of field of air conditioning, more particularly, to the tower heating power actified solution dehumidifier of one kind cooling
Group.
Background technology
In filed of air conditioning, summer usually requires to carry out cool-down dehumidification processing to the air that outdoor is come in, and winter is usual
Need to carry out warming and humidifying processing to the air that outdoor is come in.Mostly using dehumidification by condensation processing side in traditional air-conditioning system
Formula, i.e., prepare the cooling water of low temperature using refrigeration machine, circulates and is carried out with air in the coil pipe of surface cooler by cooling water
Heat exchange, air themperature is reduced to below dew point, makes air condense out moisture to realize the dehumidification treatments for air.
The dehumidifying of this processing mode and temperature-fall period are integrated control and while carried out, because the cooling water temperature of dehumidification requirements is far low
In the cooling water temperature needed for cooling, usually 7~12 DEG C, on the one hand, refrigeration machine is operated in the case of low evaporating temperature, lead
Cause the coefficient of performance of refrigeration machine relatively low, on the other hand, though the air humidity after dehumidification by condensation, which is met, requires that temperature is too low, typically
Also need to reheating and can be only achieved wind pushing temperature requirement, cause the secondary waste of the energy.Further, since the presence of condensate makes table
Cooler coil pipe etc. is easy to breed bacteria, gone mouldy, and reduces air-supply quality, has a strong impact on the quality of room air.
To overcome the defect that traditional air-conditioning system dehumidification by condensation mode is present, those skilled in the art has researched and developed molten
Liquid damping mode, i.e., directly contacted with fresh air as working media using the salting liquid with damping property and carry out caloic friendship
Change, when the partial pressure of water vapor of air is higher than the surface vapor pressure of salting liquid, salting liquid is absorbed by the moisture in air；And
When the partial pressure of water vapor of air is less than the surface vapor pressure of salting liquid, the operative liquid water in salting liquid is changing to gaseous state
Get into the air, so as to realize the regulation purpose to air humidity.The dehumidification by condensation mode of solution dehumidification mode and legacy system
Compare, it is not necessary to the low-temperature receiver of low temperature (7~12 DEG C) is crossed, to create condition using the extensive low-grade energy of resource；And it is molten
Salting liquid in liquid dehumidification mode is that progress heat and mass is directly contacted with air, by the filtering of salting liquid, sterilizing function,
Dust, bacterium, mould and some other harmful substance in air can be removed, air-supply quality and room air product can be effectively improved
Matter.The independent control of temperature and humidity is realized using the air-conditioning system of solution dehumidification mode, due to saving the energy and raising

Efficiency.In the process of solution dehumidification or humidification, air can have releasing for latent heat of phase change while carrying out heat and mass with salting liquid
Put or absorption process, make the temperature of air and solution while occurring quick change, and this change exactly suppresses or reduces biography
Matter motive force, in time can not such as pass latent heat of phase change, can largely influence what solution dehumidification and salting liquid regenerated
Effect and efficiency., exactly can not be fast using the salting liquid dehydrating unit and regenerating unit of heat-insulating due to the defect of self structure
Speed transfers latent heat of phase change, and the main method that this problem is solved at present is increase salting liquid internal circulating load, to suppress or to dilute
Air and salting liquid carry out the latent heat of phase change produced in heat and mass transfer process, and this processing mode necessarily can only alleviate phase transformation in journey
The adverse effect of latent heat, does not tackle the problem at its root, and on the one hand due to the preferable salting liquid of hygroscopicity, its price all compares
It is high, operation cost is increased, and the operational factor and precision of total system are difficult to control, on the other hand due to salting liquid
Usage amount is larger, will also result in overall unit and increases, increases manufacturing cost.Simultaneously this heat-insulating salting liquid dehydrating unit and
The heat exchanger of regenerative device of solution is mainly using copper, steel alloy etc. compared with the manufacture of noble metal material, and its manufacturing cost is also of a relatively high.
