Description
Technical field
The utility model relates to the variable air rate blowing out device.
Background technology
A kind of as air-conditioning system has the single pipe method of variable air rate.The single pipe method of variable air rate be from air conditioner by pipeline and blow-off outlet to blowed the air supply mode that line space transfers of going forward side by side by conditioned space.At pipeline patent documentation 1 described variable air rate device (VAV unit) is set midway.By this each variable air rate device is increased and decreased air fed air quantity, control respectively by the temperature of conditioned space.
Patent documentation 1: Japanese kokai publication hei 8-28946 communique.
The utility model content
Such mode is necessary to be provided with separately the variable air rate device outside blow-off outlet, for the variable air rate device is set in ceiling, not only need equipment cost, and the inconvenient problem of maintenance is arranged.And make under its situation that stops to blow out, the mechanism that reduces air quantity is single, therefore also has sound of the wind to reveal the problem that noise takes place.And air fed temperature is lower than normal conditions, under the situation that the cold air distribution that send a small amount of wind simultaneously carries out with the single pipe method of variable air rate, because the low air quantity of air supply temperature is few, has in the indiffusion of blow-off outlet air-flow, and the problem of cold wind air-flow and dewfall takes place.
In order to solve above-mentioned existing problems, variable air rate blowing out device of the present utility model, be to use the air supply of sending into from the outside to induce to be mixed the back to the described variable air rate blowing out device that is blown out by conditioned space (S) by the air of conditioned space (S), wherein, possess and be configured to make described air supply and the main body that is flowed by induced air within it and control described air supply and described by the air quantity regulon that blows out air quantity of the mixing ratio of induced air and mixing air.
If employing the utility model, then
