Description
Technical field
The present invention relates to a kind of air-treatment unit, particularly a kind of heat pump drives rotary wheel dehumidifying and regenerative air-treatment unit.
Background technology
China air conditioning in residential buildings system mostly adopts new return air mixed mode, because most of air is in indoor circulation, so that being discharged to that pollutant can not be very fast is outdoor, harm humans is healthy.Strengthen resh air requirement (or adopt all-fresh air method of operation), can indoor harmful substance dilute and discharge outdoorly, obviously improve indoor air quality.But then, the increase of resh air requirement is so that new wind processing energy consumption increases greatly, and new wind load accounts for the 30%-40% of air-conditioning total load.To the present dehumidification modes that adopt chilled waters or directly evaporate of the processing mode of new wind, there is the drawback of the following aspects in this air conditioning mode: one, the condensation temperature of air cooling refrigeration machine is higher, and Energy Efficiency Ratio is low more in addition; Two, for lower chilled water temperature is provided, need lower evaporating temperature, the efficient of cooling-water machine is also decreased; Three, be difficult to adapt to the variation of heat moisture ratio.Only by evaporation mode air is cooled off and dehumidify, 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 humidity, compromise by the requirement of only satisfying indoor temperature, cause the too high or too low phenomenon of indoor relative humidity; Four, because of the excessively low existence that causes condensed water of leaving air temp, 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.
This heat pump drives rotary wheel dehumidifying and regenerative air-treatment unit, and its basic function is: the new wind of unit with after return air mixes through air-treatment, send into indoor; New wind processing section then is to carry out preliminary full recuperation of heat through the air-air heat reclamation device first by new wind and air draft, then by the evaporimeter of heat pump new wind is carried out latent heat and the part sensible heat of the new wind of precooling dehumidification treatments, by desiccant wheel the further absorption type of new wind is dehumidified to process again the latent heat of new wind, near the moisture absorption process of isothermal, thereby do not exist new wind processing section temperature to cross low and danger dewfall; Utilize simultaneously the condenser heat of heat pump that desiccant wheel is regenerated, take away the moisture of desiccant wheel absorption by exhaust blower.New wind processing section is also born simultaneously and is removed indoor CO2, peculiar smell, to guarantee the task of IAQ.
In central 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.Traditional rotary wheel dehumidifying mode is that utilization efficiency of heat energy is low take steam, high-temperature-hot-water and electric heating as the renewable sources of energy, its essence is that dehumidifying and these two processes of regeneration all are constant-enthalpy processes and non-isothermal process causes very large irreversible loss.The renewable sources of energy are used instead heat pump then solved this problem, thereby realize moisture absorption process near isothermal, thereby greatly improved the Energy Efficiency Ratio of unit.
The present invention with indoor low humidity air draft as regeneration wind, utilize dehumidifying and the regeneration function of desiccant wheel to utilize simultaneously the heat pump condensation heat as reactivation heat, low taste thermal source is utilized, because heat pump can obtain the heat of Duo than drive energy, help energy-conservation and improve the environmental situation that causes because of fire coal, fuel oil; Simultaneously, the coil pipe of air-treatment part is near dry coil pipe, evaporated condensation water, and the surface of having stopped coil pipe has formed the hotbed that grows various moulds, has optimized indoor air quality.
