Description
Technical field
The utility model relates in chemical industry and medicine and other fields, and the exploitation of product and analysis need to be used vent cabinet conventionally, particularly a kind of air-replenishing type ventilating cabinet.
Background technology
The type of current vent cabinet is mainly divided into determines air quantity type and variable air delivery type two classes:
1, determine air quantity type-for the supporting exhaust system of this type vent cabinet provides maximum exhaust air rate for vent cabinet, entirely no matter whether these vent cabinets are used; Whether in use there is the possibility that reduces exhaust air rate; It is constant that total exhaust air rate all keeps.
The method early stage, construction cost was low, but still maintained maximum exhaust air rate while using, and had increased later stage operation cost.
2, variable air delivery type-be that the supporting air supplying and exhausting system of this type vent cabinet can pass through measurement and control system, according to the service condition of vent cabinet, and the aperture of adjustment doors size automatically regulate give, exhaust air rate, thereby reach energy-conservation effect.
The method can regulate exhaust air rate according to actual conditions, has saved later stage operation cost, but early stage, construction cost was higher.
For the pluses and minuses of above-mentioned 2 types of vent cabinets, on market, occurred that a kind of modified determines air quantity vent cabinet-air-replenishing type ventilating cabinet.Its cardinal principle is, directly take out outdoor air and enter the air compensation device that is installed on adjustment doors top, by air compensation device, make outdoor air form " gas curtain " in vent cabinet outside, and be finally inhaled into vent cabinet, reduce the demand of vent cabinet to air quantity in laboratory, this has not only saved construction cost in early stage, and has reduced air-conditioning system operating cost.
But the air quantity vent cabinet of determining of this benefit wind mode also has shortcoming, mainly:
1, mend wind and can directly blow to the head of experiment operator, if work long hours, can cause operating personnel's discomfort, especially the large time marquis of 2 season of summer in winter indoor/outdoor temperature-difference;
While 2, mending wind by human body, can change air flow direction, cause the front air current composition of adjustment doors disorderly, thereby probably take harmful substance out of vent cabinet, affect personal security.
If after 3 too much benefit wind enter, do not siphoned away by exhaust system, flow into the energy consumption (seeing Fig. 1,2) that house interior has increased air-conditioning system on the contrary.
Therefore, the present invention is exactly the benefit wind mode that redesigns vent cabinet, overcomes the shortcoming of existing air-replenishing type ventilating cabinet; Can reduce construction cost in early stage, can change again the energy consumption that air-flow moves towards to reduce air-conditioning system in use procedure, and promote user's comfort.
Utility model content
The purpose of this utility model is to provide a kind of air-replenishing type ventilating cabinet, mainly solve the existing technical problem of above-mentioned existing air-replenishing type ventilating cabinet, it can reduce construction cost in early stage, can change again air-flow trend, reduce the energy consumption of air-conditioning system in use procedure, and promote user's comfort.
For achieving the above object, the utility model is to realize like this.
An air-replenishing type ventilating cabinet, it comprises the air-conditioning system being connected with vent cabinet, air compensation device and the air exhausting device being arranged in laboratory; It is characterized in that: this air compensation device is arranged on vent cabinet adjustment doors both sides as main air draft air quantity source.
Described air-replenishing type ventilating cabinet, is characterized in that: these vent cabinet adjustment doors both sides are provided with the benefit wind frame with wind-supplying mouth being connected with air compensation device.
Described air-replenishing type ventilating cabinet, is characterized in that: this air-conditioning system is as the less important air draft air quantity source that is arranged on the air exhausting device of vent cabinet top.
Technique effect of the present utility model is:
1, the utility model designs by rational vent cabinet and air exhausting device wherein makes to keep negative pressure in vent cabinet, prevents that pernicious gas from overflowing in vent cabinet, thus protection operating personnel.
2, the utility model is by the both sides in adjustment doors by air compensation device design, and the main air draft air quantity source (75%～90%) using it as air exhausting device, Laboratory Air-conditioning System is less important air draft air quantity source, it can reduce from the required benefit air quantity of Laboratory Air-conditioning System, thereby reaches the object that reduces Laboratory Air-conditioning System energy consumption.
3, the utility model, by air compensation device is designed in the both sides of adjustment doors, has prevented from blowing and has directly blown the experimental implementation person crown, reduces the discomfort that it is caused.

The specific embodiment
Refer to Fig. 3,4, the utility model discloses a kind of air-replenishing type ventilating cabinet.As shown in the figure: it comprises the air-conditioning system 3 being connected with vent cabinet 5, air compensation device 1 and the air exhausting device 2 being arranged in laboratory 4.This air compensation device 1 is arranged on vent cabinet 5 adjustment doors both sides as main air draft air quantity source, can control the air output of air compensation device 1, guarantees that the face wind speed of vent cabinet approximates 0.5m/s.
These vent cabinet 5 adjustment doors both sides are provided with the benefit wind frame with wind-supplying mouth 11 being connected with air compensation device 1.
This air-conditioning system 3 is as the less important air draft air quantity source that is arranged on the air exhausting device 2 of vent cabinet 5 tops.
By said structure, this utility model has following features:
1, the face wind speed that the air output of the air compensation device 1 of adjustment doors both sides can meet vent cabinet maintains certain limit, thereby guarantees that the gas in vent cabinet is not excessive, Protection operating personnel's safety.
2, air compensation device 1 is the main air draft air quantity source (75%～90%) of air exhausting device 2, and Laboratory Air-conditioning System 3 is less important air draft air quantity source.
3, special vent cabinet adjustment doors and the integrated design of benefit wind frame, make 75% ~ 90% of vent cabinet 5 required exhaust air rates be provided by the benefit wind frame with wind-supplying mouth 11.
4, special wind-supplying mouth 11 designs, make outdoor benefit wind be close to vent cabinet adjustment doors both sides and enter vent cabinet 5, greatly reduce outdoor air on operating personnel and indoor temperature on impact.
5, benefit air quantity and the blast of appropriate design air compensation device 1, make to mend wind energy and form " gas curtain " at the uniform velocity, covers more than 80% vent cabinet aperture area, prevents that in cabinet, gas escapes, and meets the safety requirements of vent cabinet.
Above-mentioned utility model structure is applicable to all experiments place that comprises vent cabinet.
Be only preferred embodiment of the present utility model in sum, be not used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modify, all should be technology category of the present utility model.
