The design of high-precision constant temperature and humidity laboratories also has certain classification standards. Now many companies pursue high precision when designing laboratories. How to achieve high-precision constant temperature and humidity laboratory design requires certain data standards and indicators.
Realize the temperature fluctuation range control of ±0.5℃ in a larger space; the relative humidity fluctuation range is controlled by ±2%, meeting the requirements of high-precision constant temperature and humidity environment. Then to achieve a high-precision constant temperature and humidity laboratory, we must pay attention to four aspects.
The decoration must strictly achieve the effect of heat preservation and moisture insulation: high-precision constant temperature and humidity air conditioning is the key:
high-precision constant temperature and humidity air conditioning must be able to adjust the cooling capacity according to the temperature difference. Now the real high-precision constant temperature and humidity air conditioning has two ways to adjust the cooling capacity: chilled water type and variable frequency type. Use cold water of about 7℃ from ordinary central air conditioners, install a valve as simple as a faucet for control, when cooling is not needed, close the valve, when cooling is required, open the valve, and the valve opening is like a faucet, which can be large or small, truly realizing 0% to 100% adjustment of water flow, easily achieving cooling capacity adjustment, very stable control of temperature and humidity, and almost 0 failure rate.
In addition, the wind of the high-precision constant temperature and humidity laboratory not only guarantees the laboratory staff's demand for fresh air, but also contributes to and is indispensable to ensuring the stability of temperature and humidity, because the temperature and humidity outside the laboratory vary greatly with the seasons. In order to ensure that the laboratory is not affected by the outside world, the only effective way is to add fresh air to the laboratory and ensure that the laboratory air pressure is positive, so that the unqualified air that changes at any time from the outside world cannot be mixed into the laboratory, ensuring the long-term stability of the laboratory.
