Tube-in-tube condenser 13 with flow through solution pump I 8 weak solution exchange heat, be cooled after enter air cooled condenser I 14 by air into
One step is cooling, condenses into highly pressurised liquid.If the condensation heat that tube-in-tube condenser 13 undertakes and cooling system amount, compressor wasted work
When reaching balance, refrigerant is after the outflow of tube-in-tube condenser 13, directly through regulating valve 15, air-cooled condenser not work at this time
Make, otherwise flow control valve 15 is closed.Highly pressurised liquid flow through expansion valve I 16 throttling, become low pressure, low temperature damp steam, then into
Enter bushing type evaporator 17 and exchanges heat with the solution for flowing through solution pump II 9, after the heat of absorbent solution, low pressure liquid therein
Refrigerant gasifies again in evaporator, then flows through compressor I 12 and is re-compressed, and recycles so as to complete one.
Solution dehumidification circulation: divide two-way by the solution that dehumidification solution case 4 flows out, flow through flow control valve III 10 all the way, separately
Weak solution passes through flow control valve IV 11 all the way, flows through plate heat exchanger 7 and flows through the heat exchange of II 6 concentrated solution of flow control valve, quilt

Tube-in-tube condenser 13 and refrigerant heat exchanger therein enter regenerator 1 after being heated up, with process air cooled condenser II
The air of 21 heating carries out heat, mass transter, and the moisture in solution enters air, and solution concentration, which increases, becomes concentrated solution.After regeneration
Concentrated solution flow into actified solution case 2, divide two-way to flow through flow control valve I 5 all the way, another way flows through flow control valve II 6, so
It exchanges heat afterwards into plate heat exchanger 7 with the solution for flowing through flow control valve IV 11, be cooled cooling, then and from dehumidification solution
Case 4, the weak solution for flowing through flow control valve III 10 are mixed in a certain ratio.Mixed solution under the action of solution pump II 9,
Bushing type evaporator 17 and refrigerant heat exchanger therein are flowed through, enters dehumidifier 3 after the cooling that is cooled, with entrance dehumidifier 3
Air carries out heat, mass transter, and solution absorbs the moisture in air, and solution concentration, which reduces, becomes weak solution, flows into dehumidification solution case
4, to complete a circulation.
Solution dehumidification cyclic part, the course of work of regeneration air: it is cold to flow through air-cooled type under the effect of blower II 24 for fresh air
Condenser II 21 and refrigerant heat exchanger therein enter regenerator 1 and weak solution therein carry out heat, matter is handed over after being heated up
It changes, is discharged into atmosphere after the moisture in absorbent solution.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
