Laser Room with High-Precision Constant Temperature, Humidity and Clean Environment

Constant Temperature & Humidity Clean Laboratory

Constant temperature & humidity clean laboratory is a flagship service of Freshair, backed by a full range of innovative technologies and rich project experience. Leveraging advanced air conditioning and lab technologies, we precisely regulate indoor temperature, humidity and other environmental parameters within designated ranges to meet relevant laboratory and testing standards. As essential infrastructure for product and commodity quality inspection in manufacturing enterprises, such laboratories directly affect the accuracy of test results.

Freshair offers design and turnkey implementation services for constant temperature & humidity laboratories. We serve research institutions, manufacturers and organizations in textile testing, apparel testing, metrology & calibration, coating testing, packaging testing, precision machining and coordinate measuring, all demanding high-precision thermostatic, humidistatic and clean environments.

≤ ±1%RH: For laboratories for scientific research, R&D and testing

Airflow Design Essentials

Air distribution design is one of the key factors affecting the precision of high-precision constant temperature & humidity clean laboratories. When designing air distribution for such facilities, the following principles shall be followed: adopt a rational airflow layout to maximize the cooling or heating effect of supply air; create a stable and uniform temperature field, ensuring the temperature difference between the incoming airflow and the working area does not exceed the permissible fluctuation range; maintain an airflow velocity of approximately 0.25 m/s when the air reaches the working area. As a proven best practice for high-precision constant temperature & humidity laboratory design, Freshair applies radiant air conditioning combined with full-perforated and partial-perforated plate air supply, along with uniform return air at the lower part. This solution delivers superior temperature and humidity control and excellent energy efficiency.

Heat Preservation & Insulation Measures

Thermal insulation and airtightness are critical in the construction of constant temperature and humidity laboratories. Laboratories with sound insulation and airtight performance can save energy, improve temperature and humidity precision and cut operating costs.
