Abstract
The utility model provides an air supply and return structure of an air conditioner in a laboratory. The air supply and return structure comprises a blower, air supply outlets and air return inlets, wherein the upper part in the laboratory is separated into one or more than one cold air pressure equalizing area by an upper air hole board; the lower part in the laboratory is separated into one or more than one hot air pressure equalizing area by a lower air hole board; a plurality of air holes are formed on both the upper air hole board and the lower air hole board; the blower outside the laboratory blows the cold air into the cold air pressure equalizing area at the upper part through the air supply outlets; and the cold air falls in the laboratory through the air holes on the upper air hole board, then penetrates the air holes on the lower air hole board, and finally returns to the blower through the air return inlets on the hot air pressure equalizing area with the aid of a pipe. The air supply and return structure has the benefits that according to the principle that the density of the cold air is larger than that of the hot air, the cold air penetrates the air holes and goes down under the action of the self specific weight, and then is recovered by the air return inlets below, so that the convection of air is avoided, the influence on detection precision is reduced, and the operating temperature is ensured at the same time.
Description
Technical field
The utility model relates to a kind of air-conditioning mounting structure, especially relates to a kind of laboratory air-conditioning air blow and return structure.
Background technology
In office work places such as factory building, laboratories,, usually need operating temperature constant in order to guarantee constant condition of work; But existing air-conditioning air blow and return structure directly is placed on the top with air outlet; Return air inlet is placed on the below, like this can have wind and produce in the convection current of indoor formation air.For some test experience chamber, impacting being directly exposed to the instrument that detects in the air failing to be convened for lack of a quorum of air influences last accuracy of detection.And the local temperature near from air outlet is low, and local temperature far away is high, and temperature is unbalanced in the space.
The utility model content
The purpose of the utility model provides a kind of simple in structure, safe and reliable laboratory air-conditioning air blow and return structure.
The technical scheme of the utility model is: a kind of laboratory air-conditioning air blow and return structure; Comprise blower fan, air outlet and return air inlet; The top is separated out the equal nip of one or more cold air by last diffusing wind orifice plate in the laboratory; The below is separated out the equal nip of one or more hot gas by following diffusing wind orifice plate in the laboratory; Said go up to loose the wind orifice plate be distributed with some diffusing wind holes on the diffusing wind orifice plate down, the said blower fan that is positioned at is sent cold air into the equal nip of cold air of said top through said air outlet in the laboratory outside, cold air drops in the laboratory through the said diffusing wind hole of diffusing wind orifice plate; Pass down the diffusing wind hole on the diffusing wind orifice plate again, get back in the blower fan through pipeline by the said return air inlet that is installed in the equal nip of hot gas.
Preferably, said return air inlet is installed on the bottom or wall of the equal nip of hot gas.
Preferably, said return air inlet is installed on the bottom and wall of the equal nip of hot gas.
Preferably, the square hole that said diffusing wind hole is square hole or circular hole or band raster or for cellular, and evenly distribution on last loose wind orifice plate and diffusing wind orifice plate down.
Preferably, said diffusing wind hole evenly distributes around the wind orifice plate upper edge of loosing down.
Advantage and the good effect that the utlity model has are:
Owing to adopt technique scheme, can pass through the big principle of cold air specific heat atmospheric density, make cold air pass diffusing wind hole and sink voluntarily according to self proportion; Reclaimed by following return air inlet again, can avoid the convection current of air like this, do not have the wind sense; Minimizing is to the influence of accuracy of detection; Also guaranteed simultaneously the temperature equalization in the whole working space, the temperature error between each point is little, feels comfortable; Have simple in structure, easy to maintenance, the production efficiency advantages of higher.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is a partial schematic diagram of going up the wind orifice plate that looses in the utility model.
Among the figure:
1, blower fan 2, air outlet 3, return air inlet 4, the last wind orifice plate that looses
5, the equal nip of the equal nip of cold air 6, down diffusing wind orifice plate 7, hot gas 8, the wind hole looses
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
As depicted in figs. 1 and 2; The utility model comprises blower fan 1, air outlet 2 and return air inlet 3; The top is separated out an equal nip 5 of cold air by last diffusing wind orifice plate 4 in the laboratory; The below is separated out an equal nip 7 of hot gas by following diffusing wind orifice plate 6 in the laboratory; Said go up to loose wind orifice plate 4 with all be evenly distributed with some square diffusing wind holes 8 on the diffusing wind orifice plate 6 down, the said blower fan 1 that is positioned at is sent cold air into the equal nip 5 of cold air of said top through said air outlet 2 in the laboratory outside, cold air drops in the laboratory through the said diffusing wind hole 8 of diffusing wind orifice plate 4; Pass down the diffusing wind hole 8 on the diffusing wind orifice plate 6 again, get back in the blower fan 1 through pipeline by the said return air inlet 3 that is installed in the equal nip 7 of hot gas.Said return air inlet 3 is installed on the bottom and wall of the equal nip 7 of hot gas, and evenly distributes.
In use, because cold air specific heat atmospheric density is big, the cold air that from air outlet 2, comes out accumulates in the equal nip 5 of cold air; Passing the wind hole 8 that looses according to self proportion sinks voluntarily; Reclaimed by following return air inlet 3 again,, can avoid the convection current of air like this on the wind orifice plate that looses up and down because the wind hole 8 that looses evenly distributes; Minimizing has also guaranteed the temperature of work simultaneously to the influence of accuracy of detection.
Above embodiment specifies the utility model, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
