For the laboratory decoration design, the design of the clean air-conditioning system is an important part, and the relevant norms and standards must be observed. To this end, the following will introduce the specifications for the design of laboratory clean air-conditioning systems.

List of specifications and standards for laboratory clean air conditioning system design. Specifically, the specifications for laboratory clean air conditioning system design are embodied in 7 aspects, namely: air conditioning system division, clean room pressure difference control, fresh air volume calculation, air supply calculation , Air conditioning plan determination, air conditioning unit design selection, refrigeration room design.

1. Air conditioning system division:

The main function of a clean air conditioning system is to eliminate heat and humidity interference and dust pollution in order to maintain the air quality in the laboratory. At present, clean air-conditioning systems are mainly divided into three categories: centralized, decentralized, and semi-centralized.

2. Clean room pressure difference control:

Since the clean room in the laboratory and other rooms have to maintain a stable pressure difference, the design of the clean air-conditioning system in the laboratory must comply with two standard standards-"Pharmaceutical Production Quality Management Practice (Revised in 2010)" (New GMP 2011) ) Article 48, Article 3.2.4 of GB50457-2008 "Code for Design of Clean Workshops in the Pharmaceutical Industry".

3. Calculation of fresh air volume:

To accurately calculate the volume calculation, there must be three parameters. The first is the sum of the compensation indoor exhaust air volume and the fresh air volume required to maintain the indoor positive pressure. The second is the indoor fresh air volume per person should not be less than 40m³/h. 3 is the fresh air volume taken as the sum of the fresh air volume required to maintain positive pressure and the compensation indoor exhaust air volume.

4. Air supply calculation:

It needs to be calculated according to the number of air changes, and the cleanliness of the clean room is different, and the number of air changes is also different. Specifically, the number of air changes in the 10,000, 100,000, and 1 million clean rooms are 25h-1, 15h-1, and 10h-1, respectively. In addition, several rooms with high heat and humidity load can be selected in the calculation, and the air volume of the room can be calculated according to the heat and humidity load value.

5. Air conditioning plan is determined:

The so-called air conditioning scheme mainly refers to the selection of air distribution, and there are two parameters of technical requirements, supply air and return air indicators. The parameters are provided by laboratory users and are designed according to the clean requirements of biological products.

6. Design and selection of air conditioning unit:

First look at the inside of the unit. The inside should be smooth and easy to clean. The internal surface and internal parts materials should be corrosion-resistant. Secondly, look at the condensate outlet of the surface cooler. This equipment should have an automatic anti-backflow function. In addition, the differential pressure gauge is used before and after all levels of air filters in the unit, and the box body is sealed.

7. Refrigeration room design:

The design in this area must be determined according to the previous six items, only in this way can the design of the laboratory clean air-conditioning system be truly done.

The above has introduced the specifications and standards for the design of laboratory clean air-conditioning systems, and I hope it .
