Description
Technical field
The invention belongs to air water-intaking technical field, particularly a kind of air water fetching device extracting moisture from dry air energy-conservationly.
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 wettability power and the air themperature negative correlation entering its moisture absorption district of desiccant wheel, namely EAT is higher, and wettability power is more weak, and when being in high temperature low moisture environments, the wettability power of desiccant wheel declines to a great extent.
Therefore, existing device Problems existing of fetching water from dry air is: in high temperature low moisture environments, efficiency of producing drinking water is low.
Summary of the invention
The object of the present invention is to provide a kind of air water fetching device, in high temperature low moisture environments, efficiency of producing drinking water is high.
The technical solution realizing the object of the invention is: a kind of air water fetching device, 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, the air outlet of the condenser of described vapor compression refrigeration system communicates with the regeneration air entrance of described desiccant wheel, also comprise First Heat Exchanger, the high temperature air outlet of described First Heat Exchanger communicates with the moisture absorption district air intake of described desiccant wheel, the high temperature air intake of described First Heat Exchanger communicates with outdoor air, the low temperature air intake of described First Heat Exchanger communicates with the air outlet of described evaporimeter.
Compared with prior art, its remarkable advantage is that efficiency of producing drinking water is high in the present invention, because:
From the outdoor air of high temperature low moisture environments before entering the moisture absorption district of desiccant wheel, after first carrying out precooling, then carry out moisture enrichment, desiccant wheel wettability power is given full play to, ensure that the efficiency of producing drinking water of whole system.
As improvement project, after obtaining precooling from the first remove portion sensible heat of hot and humid air of desiccant wheel renewing zone, then enter evaporimeter, the ability of vapor compression refrigeration system condensation draining and the operational efficiency of unit can be improved further.
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
