Description

A kind of Fresh air handling units
Technical field
The utility model is related to Fresh air handling units group equipment technical fields, more particularly to a kind of Fresh air handling units.
Background technology
Fresh air dehumidifier is for after filtering, dehumidifying, by relatively dry and reaching outdoor air by fresh air pipeline Target relative humidity air is sent to the room, to reach comfort or craftsmanship indoor environment moisture requirement.With people's life water The humiture control of flat quick raising, room air becomes more and more important.
Patent CN 206875617 U in China disclose a kind of fresh air dehumidifier, including body and plate-fin heat exchange Device, body inner cavity is divided into first chamber, second chamber, third chamber and the 4th chamber by the plate fin type heat exchanger, described Plate fin type heat exchanger is provided with a subchannel of connection first chamber and second chamber, is additionally provided with connection third chamber and the Two subchannels of four chambers, it is inside and outside in the first chamber vertical side walls to be provided through air inlet, the vertical side of the 4th chamber Wind turbine is installed on wall, surface cooler, the surface cooler and the plate are provided between the second chamber and the third chamber Condensate drain pan is fixedly connected between fin type heat exchanger, the condensate drain pan includes water-collecting tray and water distributing tray, the water distributing tray The part distribution of plate fin type heat exchanger described in upper face is provided with the through-hole being arranged up and down.
Above-mentioned fresh air dehumidifier can improve the new wind turbine of dehumidification by condensation except the dehumidifying effect under wet cooling condition, in conjunction with indoor unit Indoor temperature and humidity independent control can be achieved, but the Fresh air handling units of the structure cannot neatly carry out operating mode switching and realize heating operating mode With ventilation operating mode operation.
Utility model content
For deficiencies of the prior art, technical problem to be solved in the utility model is:How one is provided Kind can cooling operating mode and except wet cooling condition to fresh air cooling dehumidification, heating operating mode heats fresh air, operating mode of divulging information directly is blown, Realize that unit flexibly switches to improve the Fresh air handling units of heat exchange efficiency in annual different operating modes.
In order to solve the above-mentioned technical problem, the utility model uses the following technical solution:
A kind of Fresh air handling units include the body with inner cavity, and body one end is provided with air inlet, and the other end is provided with outlet air Mouthful, further include the plate fin type heat exchanger being arranged in body inner cavity middle and lower part position, is provided with above plate fin type heat exchanger Heat exchanger is additionally provided with partition board, the plate fin type heat exchanger and heat exchanger and partition board in body inner cavity by body inner cavity point For the first chamber below air inlet one end, the second chamber above outlet air one end, the above air inlet one end Three chambers and the 4th chamber below outlet air one end, flow channels on the heat exchanger are by second chamber and third chamber It is connected to, a subchannel of connection first chamber and second chamber is provided on the plate fin type heat exchanger, is additionally provided with connection Two subchannels of third chamber and the 4th chamber, the heat exchanger lower surface are provided with water-collecting tray, water-collecting tray water outlet face plate A subchannel on fin type heat exchanger is located at the outlet end setting of second chamber;It is characterized in that, the partition board includes being used for The first partition that first chamber and third chamber are separated, and for second chamber and the 4th chamber to be separated second every Plate, first partition are rotatably arranged in body inner cavity close to air inlet position, when first partition turns to the first working position Air inlet is connected to first chamber, air inlet and third chamber, second partition when first partition turns to the second working position It is rotatably arranged in body inner cavity close to air outlet position, air outlet and the 4th when second partition turns to the first working position Chamber, air outlet is connected to second chamber when second partition turns to the second working position.
In this way, partition board is rotatably arranged in this programme, cooling operating mode and when carrying out cooling and dehumidification except wet cooling condition, adjust every The shaft of plate makes partition board ensure that air inlet is fully located at first chamber, and air outlet is fully located at the 4th chamber.Outdoor fresh air passes through Air inlet enters first chamber, and the fresh air in first chamber enters through a subchannel in second chamber, the wind warp in second chamber Dew point wind is formed after heat exchanger cooling and enters third chamber, and the indoor dew point wind of third chamber enters the 4th chamber through two subchannels It is interior, it is then discharged through wind turbine, completes the cooling and dehumidification of fresh air in this way.Fresh air endlessly enters the second chamber from first chamber Room, dew point wind endlessly enter the 4th chamber, such fresh air and dew point wind mediate contact from third chamber, utilize dew point wind Cold a degree of refrigeration is carried out to fresh air, while dew point wind will produce a degree of heating, the wind after will heat up To interior, the problem that can preferably avoid dehumidifier wind pushing temperature low.Cooling and dehumidification is carried out to wind using heat exchanger, can be reduced The humidity of room air so that indoor environment is more comfortable.When being cooled down to wind, the vapor in wind can adhere to heat exchanger Condensed water is formed on heat exchanger tube in heat exchanger, condensate water collecting in water-collecting tray, collect condensed water and make in gravity by water-collecting tray With lower free-falling on the part that plate fin type heat exchanger is located at second chamber, then condensed water flow to first through a subchannel In chamber.Condensed water carries certain cold, and when fresh air enters second chamber through a subchannel, condensed water can play one to fresh air Fixed cooling effect avoids the waste of energy preferably using the cold in condensed water.
