Description
Technical field
The present invention relates to a kind of dehumidifying fresh air conditioner, particularly energy-saving low humidity fresh air conditioner.
Background technology
China's air conditioning in residential buildings system mostly adopts new return air mixed mode, and because most of air is in indoor circulation, what it is such that pollutant can not be very fast is 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; to the processing mode dehumidification mode adopting chilled water or directly evaporation at present of air more; the increase of resh air requirement makes Fresh air handing energy consumption greatly increase; and leaving air temp is lower than room dew-point temperature; the easy dew condensation phenomenon of air outlet, and the discomfort of human body when Airflow Pattern Designing is bad, can be caused; 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.
This energy-saving low humidity fresh air conditioner, its basic function is: the new wind of hot humid carries out Total heat exchange with the new wind of low temperature after surface-type heat exchanger process by air-air total-heat exchanger; On the one hand, the new wind of entrance, through the preliminary cool-down dehumidification of air-air total-heat exchanger, reduces the load of surface-type heat exchanger; On the other hand, after the new wind of the low temperature after surface-type heat exchanger process is heated up by the heat exchange of air-air total-heat exchanger, temperature suitably raises, and relative humidity reduces further, is sent into indoor, thus there is not the danger of the too low condensation of leaving air temp by blower fan.Fresh air conditioner is also born simultaneously and is removed indoor CO2, peculiar smell, to ensure the task of IAQ.
Native system has also carried out precooling to new wind while utilizing the energy of new wind to carry out reheating to the new wind of low temperature and low humidity, reduce Fresh air handing energy consumption, improve Energy Efficiency Ratio, low taste thermal source is utilized, contribute to environmental situation that is energy-conservation and that improve because coal-fired, fuel oil cause.
Summary of the invention
Object of the present invention aims to provide a kind of simple and reasonable, energy-saving low humidity fresh air conditioner that energy consumption is low, to overcome weak point of the prior art.
By the energy-saving low humidity fresh air conditioner that this object designs, be made up of blower fan, air-air total-heat exchanger, surface-type heat exchanger and multiple air-valve.
Described energy-saving low humidity fresh air conditioner, is characterized in that described air-air total-heat exchanger is board-like or rotaring wheel structure, and material is clear water film aluminium foil or other macromolecular materials; The A face of air-air total-heat exchanger and D face are between fresh inlet and blower fan and separated by dividing plate, and the A face of air-air total-heat exchanger and D face are equipped with air-valve 5 and air-valve 6 respectively; New wind passes through surface-type heat exchanger after air-air total-heat exchanger; a dividing plate is had to separate between the inlet side of surface-type heat exchanger and blower fan; dividing plate is equipped with air-valve 4, has a dividing plate to separate between the air side of surface-type heat exchanger and fresh inlet, dividing plate is equipped with air-valve 3; Indoor are sent into by blower fan after new wind after surface-type heat exchanger process and the new wind of fresh inlet carry out Total heat exchange by air-air total-heat exchanger.The top of air-air total-heat exchanger 1 also has a C-D direction air duct, and A-B direction air-flow by this air duct, passage is not equipped with air-valve 7; The new wind part of low temperature and low humidity after surface-type heat exchanger process is by air-air total-heat exchanger and air-valve 6, another part is not by air-air total-heat exchanger but the air duct of air-valve 7 is housed by its top, sent into indoor after the mixing of two parts air by blower fan; Air-valve 7 plays and regulates two parts AIR Proportional, and then the effect of regulating outlet air temperature.
When outdoor air is hot humid air, air-valve 5 and air-valve 6 are opened, and air-valve 3 and air-valve 4 are closed; Outdoor new wind is successively through air-valve 5
,be divided into two strands of air after air-air total-heat exchanger A-B direction and chilled water surface-type heat exchanger (or direct-expansion type evaporimeter), portion of air is through air-air total-heat exchanger C-D direction
,air-valve 6
,another part air is directly through upper channel and the air-valve 7 of total-heat exchanger
,then sent by blower fan after the mixing of two parts air; The new wind of new wind after surface-type heat exchanger cool-down dehumidification and outdoor carries out Total heat exchange by air-air total-heat exchanger, because the new air temperature after surface-type heat exchanger process is lower than the new wind dew-point temperature in outdoor, outdoor new wind has condensed water through total-heat exchanger and separates out; Meanwhile, the new wind after surface-type heat exchanger cool-down dehumidification, part temperature after air-air total-heat exchanger raises, and relative humidity reduces further.The object of surface-type heat exchanger reaches low dew-point temperature by chilled water or refrigerant evaporation, the moisture in the new wind in outdoor of removing hot humid; The object of air-air total-heat exchanger first carries out pre-cool-down dehumidification to the new wind in outdoor, to reduce the load of surface-type heat exchanger, heats up simultaneously its relative humidity is reduced further to the new wind after surface-type heat exchanger cool-down dehumidification.
When outdoor air humiture is too low, air-valve 5
,air-valve 6 and air-valve 7 are closed, and air-valve 3 and air-valve 4 are opened; Outdoor new wind is successively through air-valve 3
,hot water surface's formula heat exchanger (or direct-expansion type condenser)
,air-valve 4
,blower fan; Hot water surface's formula heat exchanger heats new wind; Also can add that humidifier carries out humidification to new wind in surface-type heat exchanger outlet.
The present invention has also carried out precooling to new wind while utilizing the energy of new wind to carry out reheating to the new wind of low temperature and low humidity, reduce Fresh air handing energy consumption, improve Energy Efficiency Ratio, low taste thermal source is utilized, contribute to environmental situation that is energy-conservation and that improve because coal-fired, fuel oil cause.
