Embodiment Construction

[0015] The method for solving the problem of air supply uniformity in a large-area, large-space and high-precision environment of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0016] The method of the present invention to solve the uniformity of air supply in a large area, large space, and high-precision environment is to adopt the method of horizontal air supply and horizontal return air. The air supply side of the clamping wall is composed of the orifice plate of the air supply boss. The orifice plate of the air supply boss includes an orifice with holes evenly distributed, a conical boss with a large air inlet and a small air outlet, that is, in the conical boss There is an air duct and the air inlet of the air duct is large and the air outlet is small. Each hole on the orifice plate is fixed with a conical boss. The opening rate of the orifice plate is k = 0.2% to 5%, and the flow rate of the orifice is ≤ 4m...

Abstract

The invention discloses a method for solving the problem of air supply uniformity in a large-area, large-space and high-precision environment. A horizontal air supply and horizontal air return mode is adopted in the method, wherein the horizontal air supply means to supply air to the large space through a horizontal air supply sandwich wall, and the air supply side of the horizontal air supply sandwich wall is formed by an air supply lug boss orifice plate; and the air supply lug boss orifice plate comprises an orifice plate in which holes are uniformly distributed and conical lug bosses, air flues are arranged in the conical lug bosses, the air inlets of the air flues are big, the air outlets of the air flues are small, a conical lug boss is fixed in each hole of the orifice plate, the porosity k of the orifice plate is 0.2 to 5 percent, the escape velocity of the holes is less than 4 meters per second, and the ratio of the air flow velocity vertical to the escape direction of the holes before the flow escapes the holes to the flow rate of the holes is less than or equal to 0.25. According to the method, the requirements of control precision, stability and uniformity of the air in a working area can meet the international requirements, and the stability, the uniformity and the precision of the temperature and the humidity of the air in the large-area large space are effectively ensured.

Description

technical field [0001] The invention relates to a method for solving the problem of air supply uniformity in a large-area, large-space, and high-precision environment. Background technique [0002] At present, in a large area and a large space environment, in order to solve the problem of long air supply distance and large air supply volume, the air supply methods mainly include nozzles and swirling air outlets. The nozzle is generally used in projects that can be installed horizontally. Its advantages are easy installation, long-distance air supply, adjustable air outlet direction, high jet velocity, and long air supply distance. As a result, the vertical temperature distribution of the space is uneven, and there is a phenomenon of "stratification" of temperature and humidity, which cannot guarantee the stability and uniformity of the indoor air at all; the swirling air outlet is generally used in projects that can be installed vertically, and its advantage is that it can ...
