Because hygroscopic solution obtains everybody concern gradually in the superiority of removing on the indoor latent heat load.Liquid desiccant air conditioning is compared with conventional air-conditioning, saves a large amount of electric energy thereby can adopt low-temperature heat source to drive; Can remove airborne dust, bacterium, mould and some other nuisances by the sprinkling of solution; Avoid using the coil pipe of condensate water, can obviously improve indoor air quality.
Summary of the invention
The purpose of this invention is to provide a kind of heat recovery type fresh air treatment system that utilizes hygroscopic solution for cycle fluid.
The present invention proposes utilizes the heat recovery type fresh air treatment system of hygroscopic solution for cycle fluid, it is characterized in that, but described fresh air treatment system contains the unit spray module of heat reclamation device and temperature adjustment; Described heat reclamation device is made up of the direct contact modules of gas-liquid (1), plate type heat exchanger (2), solution self-circulating pump (3), systemic circulation pump (4), water compensating valve (5); But the unit spray module of described temperature adjustment is made up of plate type heat exchanger (2), the direct contact modules G of gas-liquid, solution self-circulating pump (3); Described fresh air treatment system is divided into upper and lower two-layer passage, and the upper strata passage is the return air treatment channel, and lower floor is new wind treatment channel; Described upper strata passage is made up of the direct contact modules A of gas-liquid, C, E, and lower floor's passage is made up of the direct contact modules B of gas-liquid, D, F, G; The direct contact modules A of described gas-liquid, B, C, D, E, F and corresponding plate type heat exchanger (2) are formed three grades of heat recovery systems, utilize summer the transpiration-cooled cold of air draft to reduce the solution temperature that enters module B, D, E, be circulation solution in six modules winter, become solution full heat recovery device, directly reclaim the heat and the wet amount of air draft; Through the new wind of heat recovery system, after the further processing of module G, send into air-conditioned room; Described plate type heat exchanger (2) carries out exchange heat with the solution that enters the direct contact modules G of gas-liquid, enters the solution temperature of this module in order to adjusting.
The course of work of this fresh air processor group is as follows:
In heat recovery system, six solution self-circulating pumps flow of the spray solution of control module A~F inside is respectively arranged, there is a systemic circulation pump to be controlled at circulation solution flow between modules A~F.In each module, solution is under the driving of self-circulating pump 3, flow into plate type heat exchanger 2 from module bottom, flow down through liquid distributor then and soak filler, solution carries out the exchange of heat and quality with new wind (or return air) in filler, last solution is got back in the bottom liquid bath of module, finishes cyclic process.In summer, directly the water spray evaporative cooling effect that utilizes moisture passes to the solution of opposite side with cold by plate type heat exchanger 2 in modules A, C, E, enters the solution temperature of module B, D, F liquid distributor with reduction, thereby improves its dehumidifying effect; Hygroscopic solution directly contacts with new wind in module B, D, F, new wind is by cool-down dehumidification, have between module B, D, the F with the solution of new wind counter-current flow taking away the moisture that from air, absorbs, the solution concentration that intermodule flows constantly reduces to be needed to concentrate regeneration and just can reuse.In summer, utilize the evaporative cooling effect of air draft like this, realized the abundant recovery of air draft cold.Winter, what circulate in modules A~F is hygroscopic solution, extracts solution by the effect of self-circulating pump 3 from module bottom, through entering the liquid distributor of module after the plate type heat exchanger temperature adjustment, solution spraying and soak into down filler, and carry out with the incoming flow air that heat is wet to be exchanged.The exchange of sensible heat (temperature) is to be that the plate type heat exchanger that media passes through (A and B, C and D, E and F) in the respective stages carries out with solution between new wind and the air draft, and the exchange of moisture (humidity) is the solution concentration variation realization of flowing between modules A~F under 4 effects of systemic circulation pump.So in the winter time, be circulation vector with solution, by the solution that plate type heat exchanger in the level and inter-stage circulate, realized the full recuperation of heat of air draft heat and moisture, new wind is heated humidification in this process.
Through the new wind after heat reclamation device (module B, D, F), need be in module G further processing just can reach the requirement of air supply parameter.In summer, what flow in the corresponding plate type heat exchanger 2 of module G is 15~18 ℃ cold water.The extraneous concentrated solution that flows into flow through in turn module G, F, D, B, opposite with new wind flow direction, constantly reduce along the concentration of journey solution.The weak solution that flows out from module B need concentrate regeneration and just can reuse, and the hot water that can adopt 60~70 ℃ is as the regeneration thermal source.Solution among the module G the effect of solution pump 3 dirty go into board-like heat exchanger 2 by cooling after, behind the liquid distributor at module top, soak into filler again, and carry out the exchange of heat and quality with new wind.In this process, the reduction that act as of cold water enters the solution temperature of module G liquid distributor, thereby improves its dehumidifying effect; No longer be in order to dehumidify, thus the supply water temperature of cold water can be under the conventional dehumidification by condensation situation about 7 ℃ bring up to 15~18 ℃.The cold water of this temperature provides condition for the use of natural cold sources such as underground water, even adopt the mechanical refrigeration mode, the coefficient of performance of refrigeration machine also is improved largely.In module G, new wind is further sent into air-conditioned room after the cool-down dehumidification processing.In winter, what flow in the corresponding plate type heat exchanger 2 of module G is hot water about 40 ℃, thereby acting as of hot water improves the solution temperature that enters module G liquid distributor and improve its humidification ability.In module G, new wind is further heated humidification, and solution is concentrated, and opens water compensating valve 5 amount of makeup water to keep the concentration of solution among the module G.
