How to choose Constant temperature and humidity test chamber structure and volume?

Constant temperature and humidity test chamber overall structure: the cooling system in the lower part of the box, the control system in the upper part of the constant temperature and humidity test chamber. The test room at one end of the air flue interlayer, the distribution of heaters, refrigeration evaporator, fan and other devices. On the left of Constant temperature and humidity test chamber has Ф50 cable hole, the door is a single door stainless steel embedded door handle. Adopt double-resistant high-temperature anti-aging silicone rubber seal, can effectively guarantee the loss of temperature in the chamber.

Constant temperature and humidity test chamber door with observation window, anti-frost device ,can switch control of lights. The observation window adopts multi-layer hollow tempered glass, and the inside bonding film conductive film heats defrost. Lighting is imported Philips lamp, you can effectively observe all aspects of the work room of the test sample changes.

The volume of the constant temperature and humidity test chamber: when put the test product into the test chamber for testing, in order to ensure that the atmosphere around the product to be tested to meet the test requirements of the environmental conditions, climate chamber work space size and the size of the tested product size Should follow the following provisions:

1.The volume (W × D × H) of the tested product shall not exceed (20-35) (20 is recommended) for the effective working space of the test chamber. It is recommended to use no more than 30 for products that are heating in the test.

2. The ratio of the wind-breaking area of the tested product to the total working area of the test chamber on the section is not more than 35-50. (35 is recommended).

3. The surface of the tested product should be kept at least 100-150mm away from the wall of the chamber(150mm is recommended).
