refrigeration system
System concept: This type of laboratory adopts the industry-leading temperature balance technology (cooling without heating), which uses energy regulation technology to balance temperature control without the need for additional heating during cooling and low-temperature balance. Energy regulation technology, also known as PID control, regulates the flow rate of refrigerant by adjusting the quality of refrigerant entering the evaporator per unit time to achieve precise control of refrigeration power and temperature in the laboratory.
Compared to the previous "balanced temperature control method" of heating and cooling at the same time, the energy consumption is very high. The application of this technology can significantly reduce customers' operating costs and extend the lifespan of compressors, saving them a considerable amount of electricity expenses throughout the product lifecycle
Refrigeration evaporator: A corrugated fin refrigeration evaporator is used, located in the air duct interlayer at one end of the test chamber, and is forcibly ventilated by a blower motor for rapid heat exchange.

Structural characteristics:

Adopting superior quality304Mirror stainless steel material, processed and formed using the most advanced processing equipment currently available in China, ensuring precision and aesthetic appearance.

A.Inner box material:SUS#304Stainless steel mirror version

B.Outer box material: Cold rolled steel plate with electrostatic spray coating (baked paint type) or stainless steel sandblasted plate (stainless steel type)

C.Insulation material:PUrigid foam High density aluminum silicate cotton

D.view regard Window: Three layers of vacuum glass are used for easy observation of the test sample, and high brightness window lighting is added for easy observation of the test sample.

E.Box movement: Install four universal casters for high strengthPUMaterial, convenient for moving the box, with four support frames.

F.lead Line Hole: located on the left side of the box, standard diameter50mmUsed for external testing of power or signal lines - the aperture and number of holes can be increased as required.

Adopting the original imported dedicated human-machine interface temperature and humidity controller, the performance is reliable, the operation is easy, the control technology has reached the current international advanced level, and the cost-effectiveness is significantly better than similar imported equipment. The BTHC balanced temperature and humidity control method is adopted, making it an ideal equipment for conducting constant temperature and humidity tests.
