Condensation be due to high temperature, high humidity gas when encountering cryogenic object, reach dew-point temperature and liquefy on its surface
For liquid the phenomenon that.Existing fresh air purified scavenger in use, can all have dew condensation phenomenon appearance, especially enter in fresh air
Mouthful to heat exchanger leading portion with after heat exchanger to return air outlet section into air draft cross position and may with environment generate the temperature difference
It is easy to appear dew condensation phenomenons for position.
The harm that dew condensation phenomenon occurs in fresh air purified scavenger mainly has at 2 points：One, condensed water may be blown out from air port, be blown
Entering room makes air humidity increase, and causes human body sensory uncomfortable, and also room clothing can be made to make moist, household is mouldy；Two, wind
Ponding inside pipe, growth goes mouldy, bacterium.These bacterium mould viruses are abound with home room with fresh air, if sucking human body, can endanger
Evil family health.
In order to solve the condensation problem of existing fresh air purified scavenger, generally use condensate drain pan and connected to it solidifying
The condensation generated inside fresh air purified scavenger is drained into outside by knot water pipe line.But it has the following disadvantages：1. condensate drain pan
It is smaller so that the condensate drain pan under unit cannot completely include unit, and the water of surface cooler condensation will drip to outside disk, in addition,
If fan coil is following without condensate drain pan with the manually, electrically valve that cold water pipe is taken over, valve handle, valve junction are easier to
There is condensation.2. condensate drain pan does not do heat-insulated processing with the connection of surface cooler, since the surface temperature of surface cooler is relatively low, condensation
If respective handling is not done in the connection of water pond and surface cooler, cold bridge is formed, is easier to occur to drip accident outside condensation.3. condensate pipe pipe
The road gradient is unreasonable, condensed water can not in time, smoothly be discharged, causes condensed water cumulative in condensate drain pan, finally full
It overflows.

Dynamic air quantity regulatory function, timing start-up or shut-off function, Auto Power On or shut-off function, clock display function, PM2.5 contents are aobvious
Show function, sleep function, temperature and humidity value display function, also has the function of " to purify ", " strong net " and " ultra-clean "；It can be with every
It selects multi-period setting to adjust air quantity, and can automatically switch.
In conclusion this fresh air purified scavenger is during assembling each equipment, it only need to be by each apparatus connecting in this nothing
The predeterminated position of condensation air channel structure directly removes the equipment from predeterminated position when needing to overhaul or clean some equipment
；Therefore, can not only prevent to coagulate using the fresh air purified scavenger of no condensation air channel structure provided by the utility model
Reveal phenomenon, also, also make each equipment installation more simply, conveniently, while being sealed after also solving each equipment installation
Not tight problem improves the performance of fresh air purified scavenger.
The course of work of fresh air purified scavenger provided by the utility model is：Outdoor fresh air by fresh air inlet 10 into
Enter in outdoor fresh air duct structure 401, meanwhile, indoor return air is got in by return air inlet in return airway structure 402, into
Enter after the outdoor fresh air in outdoor fresh air duct structure 401 passes sequentially through primary filter 5, PM2.5 filters 6 are filtered,
Into in the second channel of heat exchanger 7；It gets in the indoor return air in return airway structure 402 and enters heat exchanger 7
In first passage, indoor return air and outdoor fresh air carry out Total heat exchange, and the outdoor fresh air through heating is flowed out from heat exchanger 7, and
After being filtered by high efficiency particulate air filter 8, interior is drained by exhaust fan 14 and from fresh air outlet 12.And indoor return air then passes through heat
After exchanger 7 is discharged, outdoor is drained by return air fan 15 and from return air outlet 11.During this, because of the filtering of outdoor fresh air
The discharge process of process and indoor return air is happened in no condensation air channel structure, and since no condensation air channel structure uses
It is minimum without condensation wall thickness, avoid fresh air inlet to heat exchanger leading portion with after over-heat-exchanger to return air outlet section into
There is dew condensation phenomenon in the air draft position that crosses.Meanwhile all installing components of this fresh air purified scavenger are also disposed at no condensation wind
It in road structure, avoids installing component and external contact and generates the temperature difference, effectively prevent that " cold bridge " phenomenon occurs, fundamentally shut out
Condensation generation absolutely.
The fresh air purified scavenger of no condensation air channel structure and its composition provided by the utility model, on the one hand, pass through
It is made with default wall thickness without condensation air channel structure using EPP materials, is realized without solidifying using the wall thickness of no condensation air channel structure
Dew.On the other hand, by this without condensation air channel structure on fresh air purified scavenger, and by each equipment of fresh air purified scavenger
It is plugged in the predeterminated position without condensation air channel structure so that each equipment installation more simply, conveniently, also solves each equipment installation
Occurs poorly sealed problem afterwards.Meanwhile fresh air purified scavenger can also be prevented without condensation air channel structure using this and occur to coagulate
Reveal phenomenon, improves the performance of fresh air purified scavenger.
The fresh air purified scavenger of no condensation air channel structure provided by the utility model and its composition is carried out above
Detailed description.For those of ordinary skill in the art, to it under the premise of without departing substantially from the utility model in essence spirit
Any obvious change done will all belong to the protection domain of the utility model patent power.
