Description
Technical field
The present invention relates to filed of air conditioning, particularly a kind of solution damping temperature control fresh air conditioner unit and control method thereof.
Background technology
China's civil buildings air-conditioning system mostly adopts new return air mixed mode, because most of air is in indoor circulation, being discharged to of making that pollutant can not be very fast is outdoor, harm humans health.Strengthen the resh air requirement method of operation of brand-new wind (or adopt), can indoor harmful substance dilute and discharge outdoorly, obviously improve indoor air quality.But then, the increase of resh air requirement makes new wind handle energy consumption increases greatly.To the at present freeze drying modes that adopt of processing mode of air, there is the drawback of the following aspects in this air conditioning mode: one, need drop to dew-point temperature to air, be lower than the requirement of indoor air-supply, need heat again, cause heat loss more in addition; Two, for lower refrigerant temperature is provided, need lower evaporating temperature, the efficient of refrigeration machine is also decreased; Three, be difficult to adapt to the variation of heat moisture ratio.Air is cooled off and dehumidify by condensing mode, the sensible heat of its absorption and latent heat are than can only changing in certain scope, and the heat moisture ratio of building actual needs changes in the larger context.Generally be the control of sacrificing, compromise, cause the too high or too low phenomenon of indoor relative humidity by the requirement of only satisfying indoor temperature to humidity; Four, because of the existence of condensed water, the surface of coil pipe has formed the hotbed that grows various moulds, has worsened indoor air quality, causes multiple Cure of Sick Building Syndrome.
With professor Jiang Yi is the Tsing-Hua University and the units concerned of representative, and system development goes out humiture independence control air conditioner system, and it basic composition is: handle the system and the system that handles latent heat of sensible heat, two system's independent regulation are temperature and the humidity in the control room respectively.Handle the system of sensible heat because the temperature of its water supply is higher than the dew-point temperature of room air, thereby do not have the danger of dewfall.The fresh air processor group is born simultaneously and is removed indoor CO2, peculiar smell as the system that handles latent heat, to guarantee the task of IAQ.
In the humiture independence control air conditioner system, need the fresh air processor group that dry outdoor new wind is provided, to satisfy hydrofuge, row CO2, to arrange the demand of distinguishing the flavor of and fresh air being provided.Adopting the rotary wheel dehumidifying mode, is a kind of possible solution route, promptly is attached to the wheel surface that aglite is made with hygroscopic materials such as silica gel, molecular sieves.But the essence that the rotary dehumidifier utilization efficiency of heat energy is low is dehumidifying all is constant-enthalpy process and non-isothermal process with these two processes of regeneration, and psychrometric difference between wheel surface and air and temperature difference are all very inhomogeneous, cause very big irreversible loss.Another dehumidification mode is that air directly contacts (as lithium-bromide solution, lithium chloride solution etc.) with the salting liquid with moisture absorption, airborne steam is absorbed by salting liquid, thereby realize the dehumidifying of air, the salting liquid after the moisture absorption need concentrate regeneration and just can reuse.Adopt the solution moisture absorption, can make air solution contact surface simultaneously as heat exchange surface, the opposite side on the surface inserts cold water or hot water, realizes the purpose of the absorption or the additional heat of transformation, thereby realizes moisture absorption and regenerative process near isothermal; Can also adopt the wet crosspoint of solution air heat that has Intermediate Heat Exchanger.Be cross-current between solution and the water, if the internal circulating load of solution is enough big in the unit, the humidity variable quantity of air by such unit again hour, its irreversible loss can significantly reduce.
The hygroscopic solution that utilizes that Chinese patent literature CN2811816Y discloses on August 30th, 2006 that a kind of HVAC uses is that the heat recovery type fresh air of cycle fluid is handled unit, but described fresh air processor group 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, plate type heat exchanger, solution self-circulating pump, unit circulating pump, water compensating valve; But the unit spray module of described temperature adjustment is made up of plate type heat exchanger, the direct contact modules G of gas-liquid, solution self-circulating pump.This structure is not accurate enough to the temperature control of new wind output, is difficult to reach customer requirements.
