Abstract
The utility model relates to a spiral-flow type low temperature air feeding mouth. A circular volute chamber is provided with a nozzle connected with an air pipe along the tangential direction so as to make the primary air with low temperature ejected into the volute chamber along the tangential direction form rotary potential flow around the volute chamber. A negative pressure zone is formed at the center of the volute chamber according to rotary air current theory. The indoor secondary air with high temperature is inhaled by a central return air port; an upper air supply plate and a lower air supply plate are arranged on the lower part of the volute chamber; the indoor secondary air with high temperature is mixed with the primary air with low temperature in the volute chamber and is regulated by flow deflectors so that the cyclostrophic air is converted into the radial straight air to be delivered by a radical air outlet. The temperature of the mixed air is higher than that of the primary air, the relative humidity of the mixed air is reduced, and accordingly, the air outlet is difficult to dew. On the other hand, the secondary air and the air delivery are added so that the indoor air temperature is distributed evenly.
Description
Technical field
The utility model relates to a kind of spiral-flow type cold air distribution mouth that is used for the cold air distribution central air conditioner system.
Background technology
Because the anxiety of power supply electric power, the low-temperature cold accumulation central air-conditioning is subjected to people's favor day by day, generally adopts the air conditioning mode of cold air distribution in the low-temperature cold accumulation central air-conditioning.
The problem that cold air distribution exists is: cold air distribution is prone to the problem of air outlet dewfall, simultaneously because the minimizing indoor temperature distribution of air output is inhomogeneous.The method that solves generally is to adopt special-purpose low temperature induction air port, will once blow fully to mix with room return air and blow after improving temperature.And existing cold air distribution mouth resistance is big, energy consumption is high, complex structure, price are also more expensive.
Summary of the invention
The purpose of this utility model provides a kind of can being implemented in and realizes not dewfall, air port resistance spiral-flow type cold air distribution mouth little, simple in structure in the cold air distribution system.
The technical solution of the utility model is achieved in that the utility model has a round volute chamber, volute chamber tangentially has a spout to connect an airduct, be provided with the plate of blowing on below volute chamber, be connected with the plate of blowing down through flow deflector, spatial joint clearance forms radially air outlet.Low-temperature primary wind is entered through spout by airduct and tangentially injects volute chamber, forms rotary air potential barrier district in the volute chamber periphery.According to the swirling eddy theory therein the heart will form a negative pressuren zone, the secondary wind of indoor higher temperature is sucked by the return air inlet at center under the effect of central negative pressure, in volute chamber, mix with low-temperature primary wind, to rotate the direct current wind that wind converts to radially through the flow deflector rectification again and send, to increase air supplying distance by air outlet radially.Mixed air is because temperature will improve than a wind, and relative humidity will reduce, and the air port of therefore blowing is difficult for dewfall.
The utility model has the advantages that: the advantage that 1, has made full use of cold air distribution; 2, adopted inducing of eddy flow volute chamber not need powerful injection inducing function, low energy consumption also has big induction ratio, has reduced the air-supply energy consumption; 3, primary and secondary air mixes in the air port and is difficult in air port generation dewfall; 4, simple in structure, handling ease, cost are lower; 5, air supplying distance is far away; 6, owing to increased secondary wind, the increase of air output makes the indoor air temperature distribution uniform.
Description of drawings
Fig. 1 is the structural representation of looking up of the present utility model;
Fig. 2 is a main TV structure schematic diagram of the present utility model.
The specific embodiment
As Fig. 1, shown in Figure 2, spiral-flow type cold air distribution mouth has a round volute chamber 1, volute chamber tangentially has a spout 4, spout 4 connects an airduct 6, low-temperature primary wind is entered by airduct 6 again and tangentially enters volute chamber 1 from spout 4, one time low temperature wind will be formed centrally a negative pressuren zone 3 like the solid rotating flow therein at the potential barrier that the volute chamber periphery forms rotation, the secondary wind of indoor higher temperature is drawn into negative pressuren zone 3 through return air inlet 9, below volute chamber 1, establish air-supply plate 5 on, be connected with the plate 2 of blowing down through flow deflector 7, spatial joint clearance forms radially air outlet 8, mixes the back temperature with low-temperature primary wind and improve in volute chamber 1, after reducing, relative humidity sends by air outlet 8 radially again.
