Description
Technical field
The present invention relates to constructure ventilation technical field, especially relate to the exhaust apparatus of a kind of scalable induced VMC (Ventilation Mechanical Control System).
Background technology
Along with scientific and technological progress and economic development, air conditioning system is typically each installed in present building. But indoor gas is simply lowered the temperature or heats up by air conditioning system, gas or original gas, it does not have change, make the temperature of room air change to meet the daily life needs of the mankind simply by air conditioning system, to improve comfort level. Of long duration, it is more and more dirty that room air inevitably becomes, affect the healthy of the mankind, now it is accomplished by room air is replaced, the air of foul indoor is drained into outdoor, outdoor ozone is introduced indoor, and traditionally, above-mentioned ventilation is realized by devices such as window, exhaust fan or ventilation fans.
In view of the shortcomings of conventional ventilation device or method, at present, occur in that a kind of VMC (Ventilation Mechanical Control System), including way flow VMC (Ventilation Mechanical Control System), bidirectional flow VMC (Ventilation Mechanical Control System) and ground supply air system. Wherein way flow VMC (Ventilation Mechanical Control System) includes positive pressure type fresh air system 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 that outdoor fresh air is forcibly sent into indoor, along with being constantly blown into of fresh air, room pressure is gradually increased, gas is discharged in the gap building or special steam vent, thus realizing 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, the humidity of outdoor air can bring obvious discomfort to the mankind living in indoor more than in the outdoor air of the humidity of room air, higher temperature and higher levels of humidity inlet chamber continuously; Time in the winter time, the temperature of the outdoor air that positive pressure type fresh air system is sent here is lower than the temperature of room air, the humidity of outdoor air, less than the humidity of room air, brings obvious discomfort can in the outdoor air of lower temperature and relatively low humidity inlet chamber continuously the mankind living in indoor.
Therefore, how improving the structure and composition of positive pressure type fresh air system, to regulate from the temperature and humidity of the air in exhaust apparatus inlet chamber, and then to weaken or avoid original discomfort be that those skilled in the art need badly and solve the technical problem that.
Summary of the invention
It is an object of the invention to provide the exhaust apparatus of a kind of scalable induced VMC (Ventilation Mechanical Control System), this exhaust apparatus can improve the structure and composition of positive pressure type fresh air system, to regulate the temperature from the air in exhaust apparatus inlet chamber, and then weaken or avoid original discomfort.
