Description

A kind of exhaust apparatus of scalable induced VMC (Ventilation Mechanical Control System)
Technical field
This utility model relates to constructure ventilation technical field, especially relates to going out of a kind of scalable induced VMC (Ventilation Mechanical Control System) Wind apparatus.
Background technology
Along with scientific and technological progress and economic development, air conditioning system is typically each installed in present building.But air conditioning system is only It is that indoor gas is lowered the temperature or heated up, gas or original gas, do not change, simply by sky Adjusting system makes the temperature of room air change to meet the daily life needs of the mankind, to improve comfort level.Of long duration , it is more and more dirty that room air inevitably becomes, and affects the healthy of the mankind, is now accomplished by indoor Air is replaced, and the air of foul indoor is drained into outdoor, is introduced by outdoor ozone indoor, traditionally, on State ventilation to be realized by devices such as window, exhaust fan or ventilation fans.
In view of conventional ventilation device or the shortcomings of method, at present, occur in that a kind of VMC (Ventilation Mechanical Control System), new including way flow Wind system, bidirectional flow VMC (Ventilation Mechanical Control System) and ground supply air system.Wherein way flow VMC (Ventilation Mechanical Control System) include positive pressure type fresh air system with And negative-pressure type VMC (Ventilation Mechanical Control System).Wherein, the operation principle of positive pressure type fresh air system is substantially: and utilizes mechanical fan by outdoor Fresh air forcibly sends into indoor, and along with being constantly blown into of fresh air, room pressure is gradually increased so that gas Discharge in gap from building or special steam vent, thus realize the displacement to room air.
But, when summer, the temperature of the outdoor air that positive pressure type fresh air system is sent here is higher than the temperature of room air, room The humidity of outer air is more than the humidity of room air, and the outdoor air of higher temperature and higher levels of humidity enters room continuously Interior meeting brings obvious discomfort to the mankind living in indoor;Time in the winter time, the outdoor that positive pressure type fresh air system is sent here The temperature of air less than the temperature of room air, the humidity of outdoor air less than the humidity of room air, lower temperature and relatively The outdoor air of low humidity enters indoor continuously can bring obvious discomfort to the mankind living in indoor.
Therefore, how to improve the structure and composition of positive pressure type fresh air system, enter indoor air with regulation from exhaust apparatus Temperature and humidity, and then to weaken or avoid original discomfort be that those skilled in the art need the technology of solution badly and ask Topic.
Utility model content
The purpose of this utility model is to provide the exhaust apparatus of a kind of scalable induced VMC (Ventilation Mechanical Control System), this exhaust apparatus energy Enough improve the structure and composition of positive pressure type fresh air system, enter the temperature of indoor air with regulation from exhaust apparatus, and then Weaken or avoid original discomfort.
For solving above-mentioned technical problem, the technical scheme that this utility model provides is:
The exhaust apparatus of a kind of scalable induced VMC (Ventilation Mechanical Control System), including fresh wind tube, the first aperture valve, the internal diameter of outlet air end The first conical nozzle of internal diameter, the second aperture valve and mixing airduct less than air intake;
