The constant temperature and humidity laboratory is to pass a certain laboratory through some special equipment and technical methods to make its indoor temperature and humidity meet the requirements of a certain standard atmosphere for humidity control and testing. The constant temperature and humidity laboratory is the infrastructure for product quality inspection of production enterprises and commodity quality inspection in the field of circulation. The constant temperature and humidity laboratory is widely used in cotton spinning, wool spinning, chemical fiber, paper, packaging, tobacco production enterprises, as well as quality inspection, fiber inspection and other departments. The inspection of the physical items of the commodity must be carried out under standard atmospheric conditions. In addition to the constant temperature and humidity laboratory with conventional temperature and humidity, there are other special requirements such as low temperature of 5-18°C, high temperature of 30-80°C, low temperature with relative humidity less than 40%RH, and high humidity with relative humidity higher than 80%RH. constant temperature and humidity laboratory.
The main points of the overall design and planning of the constant temperature and humidity laboratory:
1) Temperature and humidity control range 2) Temperature and humidity control accuracy 3) Cleanliness requirements 4) Illumination requirements
5) The range of heat and humidity of the equipment 6) The way of air-conditioning supply and return 7) The balance measures of air pressure 8) The necessity of introducing fresh air
9) Necessity of system exhaust 10) Measures for thermal insulation 11) Configuration of facilities and power 12) Static electricity, vibration and noise
13) Equipment space and air-conditioning room 14) Arrangement of entry and exit passages and changing buffer areas 15) Sufficient maintenance space
16) Indoor clear height and floor load 17) Pollution, pollution and disaster prevention 18) Measurement of installation and operation costs
19) Aesthetic requirements 20) Installation cost/construction period control 21) Operation cost 22) Factors such as maintainability & elasticity
