Description
Technical field
The present invention relates to a kind of rotary wheel dehumidifying fresh air processor, particularly pump type heat low-temp recovery rotary wheel dehumidifying fresh air processor.
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, and harm humans is healthy.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 to be increased greatly, and new wind load accounts for the 30%-40% of air-conditioning total load.To the at present dehumidification modes that adopt chilled water or directly evaporate of processing mode of air, 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 through 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, compromise, cause the too high or too low phenomenon of indoor relative humidity through the requirement of only satisfying indoor temperature to humidity; Four, because of the low excessively 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 pump type heat low-temp recovery rotary wheel dehumidifying fresh air processor; Its basic function is: the evaporimeter through heat pump carries out the latent heat and the part sensible heat that through desiccant wheel the further absorption type of new wind are dehumidified and handles new wind again after the precooling dehumidifying to new wind, thereby does not exist leaving air temp to cross the danger of low dewfall; Utilize the heat pump condenser heat that desiccant wheel is regenerated, take away the moisture of desiccant wheel absorption through exhaust blower.The fresh air processor group 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.The traditional rotating wheel dehumidification mode is to be the renewable sources of energy with steam, high-temperature-hot-water and electric heating, and utilization efficiency of heat energy is low, its essence is that dehumidifying and these two processes of regeneration all are constant-enthalpy processes and non-isothermal process causes very big irreversible loss.Add heat pump and then solved this problem, thereby realize moisture absorption process, thereby improved the Energy Efficiency Ratio of unit greatly near isothermal.
The present invention with indoor low humidity air draft as regeneration wind; Utilize the heat pump condensation heat as reactivation heat; Make low taste thermal source be able to utilize because heat pump can obtain the heat of Duo than drive energy, help energy-conservation with improve the environmental situation that causes because of fire coal, fuel oil.
Summary of the invention
The object of the invention aims to provide a kind of simple and reasonable, pump type heat low-temp recovery rotary wheel dehumidifying fresh air processor that energy consumption is low, to overcome weak point of the prior art.
By the pump type heat low-temp recovery rotary wheel dehumidifying fresh air processor of this purpose design, form by desiccant wheel, air draft part, new wind processing section and heat pump.Solid line is represented the refrigeration working medium flow duct among the figure.The air draft treatment channel of system is got into by the upper strata, discharges outdoor successively behind the regenerating section of condenser through heat pump and desiccant wheel; New wind treatment channel is got into by lower floor, after the evaporimeter through heat pump and the absorbent portion of desiccant wheel in the inlet chamber.
Described pump type heat low-temp recovery rotary wheel dehumidifying fresh air processor is characterized in that said desiccant wheel is divided into dehumidifying part and regenerating section; The exhaust outlet of compressor is connected with an end of condenser in the heat pump, and the air entry of compressor is connected with an end of evaporimeter, and the other end of condenser is connected with the other end of evaporimeter through expansion valve.
When outdoor air is the high temperature humid air, compressor and starting, outdoor new wind is successively through evaporator, be evaporated the cold preparatory dehumidifying of device after, indoor through sending into after the desiccant wheel dehumidifying again.The purpose of evaporimeter is to reach dew-point temperature through refrigerant evaporation, removes the moisture in the moist outdoor new wind of high temperature, again through the desiccant wheel dehumidifying, to reach required air-out water capacity.Indoor exhaust wind is passed through condenser successively, utilizes condensation heat as reactivation heat, and outdoor to desiccant wheel regeneration back discharge, heat pump plays a part to reduce power consumption and improves Energy Efficiency Ratio.
When the outdoor air water capacity is fit to, close compressor, air and the air from outdoor inlet chamber in outdoor from indoor discharge carry out ventilation.
The present invention adopts heat pump techniques and desiccant wheel to handle air conditioner fresh air, through removing the dust and the bacterium of carrying secretly in the air in partly additional filtration of new wind and sterilizing unit, plays the effect that purifies air, and has improved indoor air quality; Additional heat water coil and humidifier can be in the winter time to new wind warming and humidifyings; System can reclaim the energy of indoor exhaust wind, has reduced new wind and has handled energy consumption; Utilize condensation heat that heat pump produces as reactivation heat, make low taste thermal source be able to utilize because heat pump can obtain the heat of Duo than drive energy, help energy-conservation with improve the environmental situation that causes because of fire coal, fuel oil.
