A solution absorption type cooling, dehumidification and desalination integrated fresh air unit

Abstract

The invention discloses a solution-absorption cooling, dehumidifying and desalting integrated fresh air unit which is driven through low-temperature waste heat and comprises fresh air handling units in a plurality of stages, wherein the fresh air handling units are connected in series; fresh air sequentially passes through the first-stage fresh air handling unit to the last-stage fresh air handling unit; through the heat and mass exchange with a solution in the fresh air handling units, the cooling, dehumidifying and desalting operation is performed; regenerated air sequentially passes throughthe last-stage fresh air handling unit to the first-stage fresh air handling unit; and through the heat and mass exchange with the regenerated air, the solution in the fresh air handling units is regenerated. The solution-absorption cooling, dehumidifying and desalting integrated fresh air unit disclosed by the invention has the beneficial effects that the cooling, dehumidifying and desalting integrated effect can be achieved; the waste heat utilization and the active corrosion prevention can be effectively combined; and the air quality of fresh air can be improved.

Description

technical field [0001] The invention relates to the field of fresh air treatment for air conditioning, in particular to a solution-absorbing cooling, dehumidification and desalination integrated fresh air unit driven by low-temperature waste heat. Background technique [0002] The atmospheric environment in some coastal areas of my country contains a large amount of salt mist (its main component is NaCl), and the content of salt mist is positively correlated with offshore wind. up to 10mg / m 3 . At the same time, the annual average temperature in some areas reaches 28°C, and the relative humidity is high due to the heavy rainfall. This high-temperature, high-humidity, and high-salt-fog atmospheric environment will adversely affect people's living comfort. What's more serious is that salt spray will adhere to the surface of the equipment in a high-humidity environment and produce a salt solution, which will electrochemically corrode the metal materials on the equipment, caus...

AI Technical Summary

Problems solved by technology

[0005] (1) The existing technology only uses technologies that can realize the functions of cooling, dehumidification and air desalination for simple superimposed use to realize the three functions of air cooling, dehumidification and desalination. No single device can realize the above three functions at the same time

[0006] (2) In the existing technology, the measures to realize the active anti-corrosion of equipment are mainly based on air filtration, and there is no technology that can realize the combination of waste heat utilization and active anti-corrosion

[0007] (3) The current air desalination basically adopts the combination of inertial separation method and filtration method, and the salt mist will gather into droplets when attached to the filter element and penetrate the filter net to produce secondary salt mist, and at the same time, bacteria will breed, and then the filter element will be corroded Thereby weakening the filtering effect and affecting the fresh air quality
