Embodiment 1

[0081] combine figure 1 , the clean room of the present embodiment includes an air-conditioning unit 1 and a sealed space surrounded by thermal insulation wall panels, the bottom of the sealed space is provided with a horizontal support platform 3, and the top of the sealed space is provided with an air inlet hood 2, the air inlet The cover 2 communicates with the air conditioning unit 1 through the air inlet pipe 102 ; the surrounding area of ​​the air inlet cover 2 communicates with the air conditioning unit 1 through the exhaust pipe 103 .

[0082] During the use of the clean room, the indoor temperature needs to be strictly controlled by the air conditioning unit. One of the important technical indicators is the temperature uniformity in the clean room, that is, the temperature is detected at different positions in the clean room, and the indoor temperature is compared. Whether the temperature values ​​at different positions are relatively consistent, so as to meet the req...

Embodiment 2

[0084]The structure of the clean room of this embodiment is basically the same as that of Embodiment 1. More specifically, the air inlet hood 2 is a channel with a gradually expanding aperture from top to bottom, and the height from the lower opening to the upper opening of the air inlet hood 2 is: sealed space The height=1:6.2~8.4 (specifically get 1:6.2 in the present embodiment), the aperture of the lower opening of the air intake hood 2: the width of the sealed space=1:1.4~2.7 (the width of the sealed space here refers to the sealing The narrower side of the space is long, specifically 1:1.4 in this embodiment), the top of the sealed space is provided with at least eight air outlets, and the above-mentioned at least eight air outlets are distributed equidistantly around the circumference of the air inlet hood 2, each The air outlets are all communicated with the air conditioning unit 1 through the exhaust pipe 103 .

[0085] In this embodiment, the air inlet hood 2 is set ...

Embodiment 3

[0087] combine figure 2 , the structure of the clean room of this embodiment is basically the same as that of Embodiment 2. More specifically, the upper opening of the air inlet hood 2 is provided with a sealing plate 201, and the above sealing plate 201 is provided with at least four groups of air inlets 202, each The group of air inlets 202 includes a number of air inlets 202 that are equally spaced around the center of the sealing plate, and the above-mentioned at least four groups of air inlets 202 are arranged in concentric circles, and the closer to the center of the sealing plate, two groups of air inlets are adjacent to each other. The smaller the distance between the tuyere 202 circles (that is, the several air inlets 202 included in each group of air inlets 202 are arranged at equal intervals on a circle with the center point of the sealing plate as the center of the circle, and the closer to the sealing plate The smaller the distance between two adjacent circles of...

Abstract

The invention discloses a dustless room and a construction method thereof, belonging to the field of civil construction engineering. The dustless room comprises an air conditioning unit and a closed space formed by enclosing of insulating wallboards, wherein a horizontal supporting platform is arranged at the bottom of the closed space, an air inlet hood is arranged at the top of the closed space and is communicated with the air conditioning unit through an air inlet pipe; and the circumference of the air inlet hood is communicated with the air conditioning unit through an air outlet pipe. The construction method of the dustless room comprises the following steps: A. constructing the dustless room; B. collecting dust; C. purifying air; and D. paving a floor. The temperature uniformness inside the dustless room can be promoted, and the effective heat insulation of the dustless room can be realized.

Description

technical field [0001] The invention relates to the field of civil engineering, more specifically, to a clean room for the production of integrated circuit chips, solar photovoltaic chips and the like. Background technique [0002] Clean room, also known as clean room, refers to the removal of particulates, harmful air, bacteria and other pollutants in the air within a certain space, and the indoor temperature, cleanliness, indoor pressure, airflow velocity and airflow Distribution, noise vibration and lighting, and static electricity control are within a certain range of requirements, and a specially designed room is given. It is the basis of pollution control, controlling the concentration of airborne particulates, so as to achieve the appropriate level of particulate cleanliness. Since integrated circuit chips, solar photovoltaic chips, etc. have very high environmental requirements during production, they usually need to be in a dust-free environment and control the cle...
