Description
Technical field
A kind of VMC is the utility model is related to, more particularly to one kind can realize human body respiration by reducing new air temperature
The VMC of fresh air.
Background technology
A set of independent air processing system that VMC is made up of supply air system and exhaust system, it is according to closed
Indoor side send fresh air to interior with special equipment, then from opposite side from special equipment to outdoor discharge, can be formed indoors
" fresh air field of flow ", so as to meet the needs of indoor fresh air ventilating.It is divided into duct type VMC and without pipeline VMC
Two kinds.Duct type VMC is made up of new blower fan and pipe fitting, is entered interior by new blower fan clean room outer space conductance, is passed through
Pipeline discharges room air；Without pipeline VMC by Fresh air handling units into equally being entered the room by new blower fan clean room outer space conductance
It is interior, while discharged foul indoor air by breathing treasured.Comparatively duct type VMC is more suitable for greatly work due to quantities
Industry or large area Office Area use, and without pipeline VMC because easy for installation, it is more suitable for family's use.
VMC can be divided into 1, unidirectionally flowed VMC by air supply mode classification, 2, bidirectional flow VMC, 3, give
Wind system.Wherein in supply air system, because carbon dioxide is heavier than air, therefore it is lower closer to ground oxygen content, from energy-conservation
Aspect considers that VMC is arranged on into ground can obtain more preferable ventilation effect.From floor or wall air supply at the bottom mouth or on
It is next that air outlet send cold wind to be spread apart on floor surface, forms organized air current composition；And formed around thermal source floating
Power wake flow takes away heat.Because wind speed is relatively low, air current composition turbulent fluctuation is gentle, without big vortex, thus office work area air
Temperature is layered in vertical direction in the horizontal direction than more consistent, and floor height is bigger, and this phenomenon is more obvious.Produced by thermal source
Raw upward wake flow can not only take away thermic load, also by the air of dirt from working zone band to interior top, by being located at top
Exhaust outlet discharge.The fresh air that bottom tuyeres are sent out, waste heat and pollutant under the driving force effect of buoyancy and air current composition to
Upper motion, so air-supply VMC in ground can provide good air quality in workspace indoors.
VMC is not only purified to fresh air, while the humiture of fresh air also will be controlled necessarily, is human body
One comfortable environment is provided.It is more at present that humiture is controlled using fan coil, but fan coil is difficult in adapt to interior
The change of heat moisture ratio, the control to humidity is often reduced to meet the requirement of room temperature, air handling process is restricted,
Processing to a certain item in aerial temperature and humidity, it would necessarily affect the change of another item number.Thus it is difficult to indoor warm and humid
The balance of degree, influence the comfort level of indoor environment.
To solve the above problems, each producer constantly carries out technological innovation.
Utility model content
The utility model provides a kind of VMC, it is therefore an objective to solves prior art problem, the dehumidifying in this VMC
