Description
Technical field
The utility model relates to a kind of fresh air processor group that has solution full heat recovery device that a kind of HVAC is used, and belongs to energy technology field.
Background technology
Along with the raising of living standards of the people, indoor air quality causes widely gradually to be paid close attention to.Strengthen resh air requirement or adopt the method for operation of brand-new wind, can obviously improve indoor air quality; But the increase of resh air requirement makes new wind handle energy consumption and increases considerably.Adopting heat reclamation device, reclaim the energy of indoor exhaust wind, is to reduce the effective measures that new wind is handled energy consumption.The efficient that can reclaim the full heat recovery device of sensible heat and latent heat simultaneously will be higher than heat recovering device.Full heat recovery device commonly used mainly contains rotary-type full heat regenerator and the full heat regenerator of fin plate type, and these two kinds of full heat recovery devices all can not be avoided the cross pollution of new wind and air draft, thereby have limited its application to a certain extent.
Serious day by day along with energy problem becomes as summer air-conditioning power with low grade heat energy and to press for.The a large amount of cogeneration of heat and power central heating unit of northern area can't move owing to no thermic load in summer at present, and cogeneration of heat and power in the summer power generating equipment that makes electric load the peak occur is shut down on the contrary, perhaps by pure power generation mode fallback.If can utilize this part heat drive air-conditioning, both saved the air-conditioning power consumption, cogeneration power plant is normally moved, increase generating capacity.Can slow down the pressure of powering summer like this, improve energy utilization rate again, be the key that cogeneration units continues development.Adopting absorption refrigeration, is one of solution route; But the media of the long-distance transfer heat of cogeneration of heat and power is a hot water, is that the Absorption Refrigerator energy utilization rate of power is very low with hot water, and when the supply water temperature of hot water was 90 ℃, the coefficient of performance of absorption machine was 0.6～0.7.
The utility model content
The purpose of this utility model provides a kind of fresh air processor group that has solution full heat recovery device.
A kind of fresh air processor group that has solution full heat recovery device that the utility model proposes is characterized in that: described fresh air processor group contains the direct contact modules 1 of gas-liquid, plate type heat exchanger 2, solution pump 3, water compensating valve 4, solvent valve 5; Described fresh air processor component is 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 and B, C and D, E and F form three grades of full recuperation of heat units; 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 full recuperation of heat unit, there are three solution pumps to control the flow of three grades of spray solution respectively.In each level, hygroscopic solution flows into modules A (or C, E) from module B (or D, F) bottom under the driving of solution pump 3, flow down from liquid distributor then and soak filler, and solution carries out the exchange of heat and quality with return air in filler.Afterwards, solution flows under the influence of gravity into module B (or D, F), flows down wetting filler from the top liquid distributor equally, and carries out the caloic exchange with new wind.At last, solution is got back in the bottom liquid bath of module B (or D, F), finishes the whole circulation process.In summer, the humiture of new wind all is higher than indoor return air state.Solution contacts with return air in modules A, C, E, and solution is concentrated cooling, and return air is heated humidification; Solution contacts with new wind in module B, D, F, and solution is heated dilution, and new wind is by cool-down dehumidification.Like this, be media with solution, realized that energy is by the transmittance process of air draft to new wind.In winter, the direction of heat and mass is opposite with summer, and solution is heated dilution in the modules A that contacts with return air, C, E, is concentrated by cooling in the module B, the D that contact with new wind, F, and new wind is heated humidification in this full heat recovery device.
Through the new wind after full heat recovery device (module B, D, F), need be in module G further processing just can reach the requirement of air supply parameter.In summer, the valve 5 on the solution conduit is opened, and water compensating valve 4 is closed, and what flow in the plate type heat exchanger 2 is 15～18 ℃ cold water.The extraneous concentrated solution that flows into enters module G, the solution among the module G the effect of solution pump 3 dirty go into board-like heat exchanger 2 by cooling after, soak into filler behind the liquid distributor through the module top, 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 by further cool-down dehumidification, and solution is diluted, and last weak solution flows out module G.The weak solution that flows out module G need concentrate regeneration and just can reuse, and the hot water that can adopt 60～70 ℃ is as the regeneration thermal source.In winter, the valve 5 on the solution conduit is closed, and water compensating valve 4 is opened, and what flow in the plate type heat exchanger 2 is hot water about 40 ℃, only circulation between module G, plate type heat exchanger 2 of solution.In this process, the raising that act as of hot water enters the solution temperature of module G liquid distributor, thereby improves its humidification ability.In module G, new wind is further heated humidification, and solution is concentrated, and opens water compensating valve 4 amount of makeup water to keep the concentration of solution among the module G.
The solution that this new blower fan group utilization has moisture pick-up properties is working media, but owing to adopted the single-stage spray module of solution full heat recovery device temperature adjustment, therefore new wind handle energy consumption low, can adopt low grade heat energy such as hot water as drive energy.The sprinkling of solution can be removed nuisances such as airborne dust, bacterium, mould, can play the effect that purifies air, and can avoid the cross pollution between new wind and the air draft.
