Background technology
From air, water intaking is the important channel solving water resource deficiency.Steam in air mainly for outdoor natural air, and is converted into more aqueous water by air water-intaking as much as possible.But because the difficulty of air water-intaking is very relevant to air humidity content, from the air that water capacity is little, preparing fresh difficulty is very large.
For extracting moisture from dry air, Chinese invention patent application " method of fetching water from dry air and device " (applicant: Univ. of Science and Engineering, PLA, application number: 201410799635.2, the applying date: 2014.12.19) relate to a kind of device of fetching water from dry air, comprise desiccant wheel and surface cooler, the regeneration air outlet of desiccant wheel communicates with the air intake of surface cooler, and surface cooler is the evaporimeter (as shown in Figure 1) of vapor compression refrigeration system.This device make full use of desiccant wheel under the low humidity absorption water intaking ability and vapor compression refrigeration system evaporimeter at high humidity analyse by force wet ability, realize the object of fetching water from dry air continuous, efficient, energy-conservationly, make full use of the reactivation heat of waste heat as desiccant wheel of the condenser of vapor compression refrigeration system simultaneously, the efficiency of whole method for fetching water can be improved further.
But due to desorption effect and the air positive correlation entering its renewing zone of desiccant wheel, namely EAT is higher, and desorption effect is better; For the abundant water decomposition by enrichment sucks out, need to consume the EAT that a large amount of energy improves desiccant wheel renewing zone.
Therefore, existing device Problems existing of fetching water from dry air is: energy consumption is large, and Energy Efficiency Ratio is low.
Summary of the invention
The object of the present invention is to provide a kind of solar air water intake system, energy consumption is little, and Energy Efficiency Ratio is high.
The technical solution realizing the object of the invention is: a kind of solar air water intake system, comprise desiccant wheel and vapor compression refrigeration system, the air intake of the evaporimeter of described vapor compression refrigeration system exports with the regeneration air of described desiccant wheel and communicates, also comprise solar air heater, the air outlet of described solar air heater communicates with the regeneration air entrance of described desiccant wheel.
The present invention compared with prior art, its remarkable advantage:
Energy consumption is little, Energy Efficiency Ratio is high: the present invention adopts the regeneration that solar air heater is desiccant wheel to provide energy, make moisture from desiccant wheel desorb, thus overcome the device desorb of fetching water from dry air and to consume energy large problem, from whole water intake system angle, Energy Efficiency Ratio significantly improves, and namely produces same water, the electric energy consumed significantly reduces, and replaces clean energy resource-solar energy.
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
