Description

Cabinet type split solution humidifying fresh air air conditioner for machine
Technical field
The utility model relates to air-conditioning technique field, is specifically related to a kind of cabinet type split solution humidifying fresh air air conditioner for machine.
Background technology
The civilian home air conditioning systems of China is mostly run under relative closed environment, and air, in indoor circulation, makes pollutant not to be discharged to outdoor, and harm humans is healthy.Strengthen resh air requirement (or adopting the method for operation of all-fresh air), the harmful substance of indoor can be diluted and discharge outdoor, significantly improve indoor air quality.But then, the increase of resh air requirement makes Fresh air handing energy consumption greatly increase.Adopt freeze drying mode to the processing mode of air at present more in addition, there is the drawback of the following aspects in this air conditioning mode: one, needs air to drop to dew-point temperature, lower than the requirement of indoor air-supply, need reheating, cause heat loss again; Two, in order to provide lower refrigerant temperature, need lower evaporating temperature, the efficiency of refrigeration machine is also decreased; Three, the change adapting to heat moisture ratio is difficult to.Being cooled air by condensing mode and dehumidify, its sensible heat absorbed is with latent heat than can only changing in certain scope, and the heat moisture ratio of building actual needs changes in the larger context.Be generally sacrifice the control to humidity, compromised by the requirement only meeting indoor temperature, cause the phenomenon that indoor relative humidity is too high or too low; Four, because of the existence of condensed water, the surface of coil pipe defines the hotbed growing various mould, is degrading indoor air quality, causes multiple Cure of Sick Building Syndrome.
The Tsing-Hua University being representative with professor Jiang Yi and units concerned, system development goes out humiture independence control air conditioner system, and it basic composition is: the system of process sensible heat and the system of process latent heat, and two systems independently regulate distinguishes temperature in control room and humidity.Because its temperature supplied water is higher than the dew-point temperature of room air, thus there is not the danger of condensation in the system of process sensible heat.Fresh air handing unit, as the system of process latent heat, is born simultaneously and is removed indoor C02, peculiar smell, to ensure the task of IAQ.
In humiture independence control air conditioner system, need the new wind in outdoor that Fresh air handing unit provides dry, meeting hydrofuge, arrange C02, arrange taste and the demand of fresh air is provided.Adopting rotary wheel dehumidifying mode, is a kind of possible solution route, is namely attached to the wheel surface of aglite making with the hygroscopic material such as silica gel, molecular sieve.But the essence that rotary dehumidifier utilization efficiency of heat energy is low is dehumidifying is all constant-enthalpy process and non-isothermal process with these two processes of regeneration, and the psychrometric difference between wheel surface and air and temperature difference are all very uneven, cause very large 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, steam in air is by salt-solution absorption, thus realizing the dehumidifying of air, the salting liquid after moisture absorption needs concentrating regenerative just can reuse.Adopt solution moisture absorption, air solution contact surface can be made simultaneously as heat exchange surface, the opposite side access cold water on surface or hot water, realize the object of absorption or the supplementary heat of transformation, thus the moisture absorption realized close to isothermal and regenerative process; The solution air hot and humid area unit with Intermediate Heat Exchanger can also be adopted.Be cross-current between solution and water, if the internal circulating load of solution is enough large in unit, when air is less again by the humidity variable quantity of such unit, its irreversible loss can greatly reduce.
The hygroscopic solution that utilizes that Chinese patent literature CN2811816Y discloses a kind of HVAC on August 30th, 2006 is the heat recovery type fresh air processing group of cycle fluid, and described Fresh air handing unit contains the unit spray module of heat reclamation device and temp. controllable; 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; The unit spray module of described temp. controllable is made up of plate type heat exchanger, the direct contact modules G of gas-liquid, solution self-circulating pump.This structure controls not accurate enough to the temperature that new wind exports, and is difficult to reach user's requirement.Moreover conventional Split cabinet type air-conditioning, normally requires to use in relatively airtight space, thus causes air muddiness, the anoxic in space.
