Problems solved by technology
Limited by the principle of sensible heat transfer, aluminum cores such as hydrophilic aluminum foil have been difficult to continue to improve the efficiency of heat recovery, and the total heat exchange core has high operation and maintenance costs
On the other hand, the common solution dehumidification equipment is mostly external cooling type, the solution absorbs the latent heat in the air during the process of dehumidifying the air, the temperature rises, the surface water vapor partial pressure rises accordingly, and the continuous moisture absorption capacity decreases

The invention discloses an indirect evaporation inner cooling type solution and fresh air dehumidification device which comprises a fresh air dehumidification system and a solution circulating regeneration system. The fresh air dehumidification system comprises a fresh air unit, a solution dehumidification unit and a return air unit. The solution dehumidification unit comprises a plate heat exchanger, a tap water spraying device and a solution spraying device. The fresh air unit comprises a fresh air inlet pipe and a fresh air outlet pipe. The return air unit comprises a return air inlet pipeand a return air outlet pipe. The solution circulating regeneration system comprises a solution collection trough, a dilute solution storage tank, a first solution circulating pump, a second solutioncirculating pump, a solution regeneration device and a concentrated solution storage tank. Compared with an existing fresh air dehumidification device, the device has good fresh air dehumidification efficiency, the recovery efficiency of return air cold is improved, and meanwhile the situation that secondary pollution is caused by contact of fresh air and return air is avoided.
Description
technical field [0001] The invention relates to an indirect evaporative internal cooling type solution fresh air dehumidification device, in particular to the application in the process of independent treatment of summer fresh air in HVAC projects. Background technique [0002] With the rapid improvement of people's living standards, people pay more and more attention to the comfort and health of the indoor environment. While regulating the temperature and humidity of the air, there are also requirements for indoor air quality (IAQ). In this context, fresh air equipment has attracted more and more attention. [0003] In the indoor cooling load in summer, the fresh air load can often account for about 35%, of which the latent heat load accounts for more than half of the total fresh air load. Under the social background of saving energy and reducing consumption, energy recovery has become an essential function of fresh air ventilators. On the market, sensible heat recovery m...
