Description
Technical field
Hvac equipment technical field is the utility model is related to, in particularly a kind of HVAC low temperature air supply system
End blowing device.
Background technology
Central air conditioner system can substantially be divided into normal temperature supply air system and cold air distribution system according to the difference of wind pushing temperature
System.Due to low temperature air supply system generally use ice storage technology, carry out peak-trough electricity operation and management mode, using low temperature chilled water or
Other low temperature refrigerants of person, required air output and water supply are reduced using relatively low wind pushing temperature and larger supply backwater temperature difference
Amount, reduces the investment of air-conditioner set, blower fan and water pump and airduct and water pipe, so as to reduce the expense of system equipment, because
This, compared with normal temperature supply air system, low temperature air supply system can further reduce the cost of equipment and operation pipe of air-conditioning system
Reason expense, one-time investment is reduced, improve air-conditioning quality, improve the overall efficiency of chilling air conditioning system.Therefore, low temperature in recent years
Supply air system obtains more and more extensive application.But at present there is following defect in low temperature air supply system：1）Due to cold air distribution
The air temperature that system is sent out is relatively low, if using conventional air port, can usually produce air port condensation and cold air skewness etc. and ask
Topic；2）Low temperature air supply system relies primarily on import, and expensive, hinders low temperature air supply system application at home and hair
Exhibition.
Utility model content
The utility model technical issues that need to address be to provide in a kind of HVAC low temperature air supply system use it is low
Warm air outlet, air outlet condensation can not only be prevented, avoid cold air inside skewness, additionally it is possible to reduce production cost.
In order to solve the above technical problems, technical solution adopted in the utility model is as follows.
A kind of induction type cold air diffuser, including plenum chamber, the air intake connected with blast pipe is provided with the side wall of plenum chamber
Mouthful, it is provided with air outlet on the bottom plate of plenum chamber；The nozzle of increase wind speed is provided with the air outlet, nozzle lower section passes through solid
The support being scheduled on plenum chamber bottom plate is provided with the flow deflector of guiding wind direction.
A kind of above-mentioned induction type cold air diffuser, the nozzle include the fixed nozzle body for being fitted in air outlet, nozzle sheet
Body is provided centrally with back taper spout of the axis perpendicular to plenum chamber bottom plate.
A kind of above-mentioned induction type cold air diffuser, the air inlet edge and air outlet edge decibel of the back taper spout are set
There is circular arc chamfering.
A kind of above-mentioned induction type cold air diffuser, heat-preservation cotton layer is provided with the static pressure chamber interior wall.
A kind of above-mentioned induction type cold air diffuser, the flow deflector are claw flow deflector.
A kind of above-mentioned induction type cold air diffuser, the flow deflector are the grating type flow deflector being obliquely installed.
As a result of above technical scheme, technological progress acquired by the utility model is as follows.
The utility model is simple in construction, cost is cheap, and nozzle is set by the air outlet in plenum chamber, and below nozzle
Set flow deflector, can make air port that there is good inductivity in operation, air melange effect is good, make air-supply it is extremely short away from
Carry out heat exchange from interior mix with room air, and wind pushing temperature and wind speed is decayed rapidly, reduce wind pushing temperature with
The temperature difference of indoor temperature, so as to ensure in the case of relatively low wind pushing temperature, it can also work long hours and be coagulated without air port
Reveal phenomenon.

Embodiment
The utility model is further elaborated below in conjunction with specific embodiment.
Embodiment 1
A kind of induction type cold air diffuser, its structure as shown in figure 1, including plenum chamber 1, be provided with the side wall of plenum chamber with
The air inlet 2 of blast pipe connection, is provided with air outlet on the bottom plate of plenum chamber；Nozzle 4 is provided with the air outlet, with increase
Air-supply wind speed；Flow deflector 5 is provided with below nozzle, for indoor wind to be induced into below nozzle.In the present embodiment, flow deflector is
Claw flow deflector, claw flow deflector are fixed on plenum chamber bottom plate by support.
The structure of nozzle is as shown in figure 3, including the fixed nozzle body 41 for being fitted in air outlet, the center of nozzle body 41
Back taper spout 42 is provided with, the axis of back taper spout 42 is perpendicular to plenum chamber bottom plate.In the present embodiment, back taper spout 42
Air inlet edge and air outlet edge decibel be provided with circular arc chamfering, the circular arc chamfering, which designs, make it that air flow press molding is more flat
It is sliding, reduce the resistance and noise of airflow passes spout.
To improve muting function of the present utility model, noise is eliminated, the present embodiment is provided with the inwall of plenum chamber and protected
Warm cotton layer 6, heat-preservation cotton layer use the ultra-fine fibre glass cotton after 25mm.
When the present embodiment works, First air is entered in plenum chamber from air outlet, after being cached in plenum chamber, from plenum chamber
The nozzle of bottom is sprayed with higher wind speed, and while flowing through flow deflector after First air ejection, induction room air enters inlet air
Mouth mixes progress heat exchange with First air, wind pushing temperature and wind speed is decayed rapidly, reduces wind pushing temperature and indoor temperature
The temperature difference, so as to ensure in the case of relatively low wind pushing temperature, it can also work long hours without air port dew condensation phenomenon.
Embodiment 2
