Flow pattern of air conditioning and purifying system in cleaning room

Abstract

The air conditioning and purifying system flow pattern for clean room relates to air conditioning and purifying system specially for clean room. The design scheme of the present invention includes movable floor between the clean room and the lower sandwich layer, upper static pressure box, efficient filter in the top of the clean room, and return airway on two sides of the clean room. The present invention features that inside the static pressure box, there are several self-circulating blowers with medium efficiency filtering section, surface cooling section, blower section and air outlet section. The air outlet section distributes treated air via air duct to several efficient air outlets with efficient filter and clean room successively. Each of the air outlets includes efficient filer and casing with air inlet port for connecting air duct and flow homogenizing board.

Description

technical field [0001] The invention relates to an air conditioning system, in particular to an air conditioning and purification system specially used in a clean room. Background technique [0002] With the continuous development of modern industry and science and technology, in order to ensure the high quality, high precision, high purity and high yield of products, a production environment with a high degree of cleanliness is required. For example, the production and manufacturing processes of food processing, medical and sanitary facilities, medicine, and microelectronic chips are all required to be carried out in a clean environment with constant temperature and humidity. This constant temperature and humidity and high cleanliness environment is called a clean room or clean workshop. The air conditioning and purification system configured to meet the requirements of the clean room is called the clean room air conditioning and purification system. The so-called constan...

Problems solved by technology

The cleanliness level of this form of clean room will not be too high; Figure 1 B shows that the static pressure box layer 9 is positive pressure compared with the clean room 2, and the seal between the high efficiency filter 1 and the keel frame 20 is the seal of the liquid tank 22 Form, only potting sealant 23 can ensure the cleanliness; Figure 1 C shows that the static pressure box layer 9 is positive pressure compared with the clean room 2, and the seal between the high-efficiency filter 1 and the keel frame 20 is also in the form of the liquid tank 22 , only potting sealant 23 can ensure the cleanliness; D of Fig. 1 shows: all adopt the form of FFU (that is, the fan and the high-efficiency filter form an integral unit), although the static pressure box layer 9 is negative pressure compared with the clean room 2, However, due to its small fan, the air volume and air pressure are limited, and the room for adjustment is small, which affects the service life of the high-efficiency filter 1
