Row precooling, the air after precooling successively enter wet channel 28, the air of low temperature by the gap of dry passage 27, the end of dry passage 27
It is again introduced into heat regenerator 26 and carries out recuperation of heat.Cryogenic air by dry passage 27 enter wet channel 28 when with the table of wet channel 28
The moisture film in face directly contacts, on the one hand, and air flow accelerates the evaporation of the surface moisture of wet channel 28, and mass transter occurs for Air-Water,
The heat of the wall of wet channel 28 is taken away in the evaporation of moisture, and the air of another aspect low temperature also can be with the surface moisture film of wet channel 28 in temperature
The driving of difference issues raw heat exchange, and partial heat is taken away for the wall of wet channel 28.Both sides acts on simultaneously under, wet channel 28
In the side wall that is contacted with one-level air-supply passage 6 can take away the heat discharged in dehumidification process, strengthen the performance of dehumidifier,
The side wall contacted in wet channel 28 with dry passage 27 can cause the air in dry passage to obtain lower temperature.
Solution loop is by weak solution pallet 2, solution pump 17, solution regenerator 18, solution spraying device 19, three-level two level
Between solution interface channel 20, two level one-level intermediate solution interface channel 21 form.Dense dehumidification solution is sent to from solution regenerator 18
Solution spraying device 19 sprays, and is flowed from top to bottom along wall, flows into three-level air-supply passage 14, three-level two level intermediate solution successively
Interface channel 20, two level air-supply passage 10, two level one-level intermediate solution interface channel 21, one-level air-supply passage 6, are finally converged in
In weak solution pallet 2, the weak solution in weak solution pallet 2 is sent in solution regenerator 18 by solution pump 17 to be regenerated, and is obtained dense molten
Liquid.
Dehumidification solution flows into air-supply passage from top to bottom along wall, and processed air enters air-supply passage (three from bottom to top
Level air-supply passage 14, two level air-supply passage 10, one-level air-supply passage 6), solution is opposite with the flow direction of air.Due to dehumidifying
The relatively processed air of the steam partial pressure of solution surface it is lower, in the presence of pressure differential, the water that is processed in air can be to
The lower solution surface of concentration is shifted, and the latent heat of vaporization of process release is taken away by the wall contacted with wet channel 28.With
The flowing in output channel, dehumidification process is constantly carried out, and dry air is obtained in the outlet of air-supply passage.
The water loop is by water pump 22, three-level water spray system 23, two level water spray system 24, one-level water spray system
25 compositions.Water is sent to three-level water spray system 23, two level water spray system 24, one-level water spray system 25 by water pump 22 respectively
Spray, water, which is sprayed onto on the wall of wet channel 28, is evaporated cooling.
Outdoor fresh air enters first order evaporation cooling and dehumidifying unit from three air inlets respectively, and middle air is as once
Wind enters the cooled dehumidifying in the inside of one-level air-supply passage 6, and the air on both sides enters the left dew point evaporation cooling of one-level as Secondary Air
The right dew point evaporation cooling core body 5 of core body 4, one-level, so as to produce low-temperature receiver.Air the temperature of First air, contains after coagulation
Moisture is reduced to some value, and at this moment First air is equally divided into three parts by two level plenum chamber 7 and removed into second level evaporation cooling
Wet unit, a portion enter two level air-supply passage 10, and another two parts enter the left dew point evaporation cooling core body 8 of two level, two level
Right dew point evaporates cooling core body 9.So, the estimated secondary air temperature of second level evaporation cooling and dehumidifying unit directly takes room than the first order
Outer air is low as the temperature of auxiliary air, is advantageous to cold efficiency between improving.Similarly, the two of third level evaporation cooling and dehumidifying unit
Secondary wind is derived from the part First air after second level evaporation cooling and dehumidifying unit is processed, i.e. the third level evaporates cooling and dehumidifying unit
Secondary Air temperature is the leaving air temp of the second level.It can be seen that series is higher, Secondary Air temperature is lower, and which solves conventional rack to send
Air temperature by outdoor weather condition limited and efficiency it is relatively low step by step the problem of, by the above unit structure improve after cooling effectiveness meeting
Greatly improve.
In the present invention, the temperature of wind pushing air, can be by primary air more directly using outdoor air as the low of auxiliary air
It is down to lower temperature, wind pushing temperature is limited small by outdoor weather condition, improves the whole efficiency of unit.In addition, dehumidified
The latent heat of vaporization of journey release can also be taken away by the wall contacted with wet channel, with the flowing in air-supply passage, dehumidify
Journey is constantly carried out, and dry Cryogenic air can be obtained in the outlet of air-supply passage, and this will significantly decrease air conditioning energy consumption, real
Now efficient building energy conservation.
