The clean room air conditioning system is more complex than the classical air conditioning system and the risk factor is higher. Temperature and humidity are important in classical air conditioning systems. However, in clean room systems, besides temperature and humidity, control of parameters such as air flow directions, air pressure and live and inanimate pollutants are required. In addition, the steam, exhaust air, clean water and compressed air required by the production vehicles must be met.

Sources causing pollution are collected in two main groups as living and non-living pollutants. They are microorganisms such as live pollutants, bacteria, viruses, fungi. They live in the air, on the water and especially on rough surfaces. The greatest source of live pollutants is human. The body is spread about a thousand bacteria and fungi per minute.

Non-living pollutants are the inanimate and volatile substances that occur naturally in the atmosphere. The ones whose sizes are larger than 100 millimicron are called dust. The nature of industrialization and urbanization and the quality of inanimate pollutants have also changed.

Lack of live pollutants in the products and vehicles produced, that is, the absence of microorganisms, is defined as sterile. This process is also called sterilization. In order to obtain a sterile product, pollutants should be kept at the lowest level in the production area, air, ceiling, wall and all kinds of surfaces. These rooms are specially designed and maintained under constant pressure. clean room It is called.

Depending on the type of production to be done in the clean room, the clean room class is determined. HVAC design This is done accordingly. HVAC (Heating, Ventilating and Air Conditioning) covers all branches of the ventilation industry. Many different standards are used in classifying clean rooms. Generally accepted standard Federal Standard 209E'Dr.

ISO 14644 Clean Room standard, clean rooms and environments controlled with these rooms. The basis of this standard is the 209E standard. TS 11605 standardThis standard is translated into Turkish by TSE.

This standard, implemented in 2001, consists of four headings:

  • Scope
  • recipes
  • Classification
  • Show compliance

Control procedures for monitoring and documenting the performance of production processes are called validation. The purpose of this process is to keep every step of the production stages under control. Validation operations can be made for vehicles that affect production or used in production. In this case, the specifications, installation, measurements and performance of the vehicles used are checked. Or validation procedures can be done for each product produced.

Briefly, clean room, air quality, temperature, humidity, air pressure is regulated in certain settings and the particle and micro-organisms are kept under control. Clean room testsThis is done to measure and validate these properties. There should be a clean room in the hospitals, pharmaceuticals, laboratory and food sectors which are responsible for the human health and which are responsible for the manufacturers and these clean rooms should be tested by the neutral organizations. The major tests are:

  • Particle measurement
  • Differential pressure measurement
  • Temperature and humidity measurement
  • Recovery test
  • Calculation of air flow rate and number of air changes
  • Hepa filter sealing test
