Description
Technical field
It the utility model is related to air cleaning facility technical field, more particularly to a kind of energy-saving fresh air exchange mechanism and air
Clarifier.
Background technology
In recent years, people are increasingly paid close attention to IAQ, and progressively using new blower fan or air purifier with
The air purified to indoor introducing.The major function of traditional new blower fan is ventilation, and the operation principle of new blower fan is, in a blower fan
In the presence of, fresh air inlet of the outdoor fresh air Jing Guo fresh air channel enters new blower fan, in the presence of another blower fan, room
Interior foul atmosphere enters new blower fan by the return air inlet of new blower fan, and discharge is outdoor.Room air oxygen content is improved so as to bring,
Reduce the benefit such as the volatile gas pollutant concentration such as indoor formaldehyde or purification outdoor air.But in actual applications,
Different seasons, different scenes, it is different for the demand significance level of above-mentioned each function, and phase be present in some functions
The place of mutual contradiction, is difficult to reconcile on the basis of existing equipment.For example in summer, room temperature is high, indoor formaldehyde concentration is high, should strengthen
Ventilation.Meanwhile in summer, Outdoor Air Quality relative good, the working condition of suitable new blower fan.But in the winter time, outdoor is cold
Cold, Form aldehyde release is slow, and need not be too big ventilation volume.But usual winter haze is serious, and indoor/outdoor temperature-difference is larger, now should
The reduction resh air requirement, strengthens the purification of air.The existing fresh air ventilator in market, it is by constantly importing outdoor air, leading
When going out room air and reaching a certain amount of, the clean purpose of room air could be realized.Substantial amounts of humiture is thus caused to be lost in wave
Take, increase energy loss, simple indoor purifying or simple fresh air can not be realized, that is to say, that new blower ventilating ability and net
Change ability increases and decreases simultaneously, therefore many performance loss on be present.In order to solve this problem, researcher also enters
Corresponding exploitation is gone.Such as the Chinese patent that number of patent application is 201610920637.1, it is new to disclose a kind of total heat recovery
Wind cleaning system, including：Fresh air channel, for introducing outdoor air from the exterior space, from interior after purified module purification
Air outlet introduces the interior space；Return air channel, for guiding room air into the exterior space from the interior space；Heat exchanger, newly
Air in wind passage and return air channel is respectively by heat exchanger, so as to realize heat exchange.Wherein, fresh air channel and return air
It is provided with air mixing channel between passage, the air in return air channel enters fresh air channel through air mixing channel, is set in air mixing channel
There is the first air-valve.Thus, full heat recovery fresh air cleaning system of the invention can have the work(of fresh-air ventilation and interior circularly purifying concurrently
Can, to reduce the indoor temperature change generated in case largely taken a breath and brought, and circularly purifying efficiency is improved, reduce equipment operating cost.But
This fault of construction is：1st, mainly realize that outdoor fresh air is got in, the clean room of air purifier requirement can not be met
The requirement of interior air；2nd, outdoor fresh air, indoor circulation wind need to carry out heat exchange by heat exchanger, will necessarily produce heat
Loss, especially winter or summer, in the case that indoor/outdoor temperature-difference is larger, the waste of heat can cause indoor air temperature to go out
Existing larger fluctuation.
Therefore, a kind of new energy-saving fresh air exchange mechanism and air purifier are developed, not only with urgent researching value,
With good economic benefit and commercial application potentiality, this is exactly where the power that the utility model is accomplished and basis.
