Environmental Rapid Temperature Change High and Low Temperature Test Equipment typically refers to a rapid temperature change high and low temperature test chamber, which is a device used to simulate environmental conditions and test the performance of products under temperature variations. Below is a detailed introduction to this equipment:

I. Definition and Function

It is a device capable of rapidly adjusting temperature and simulating high and low temperature environments. It is primarily used to test the performance of materials and equipment under temperature conditions, such as electronic components, automotive parts, and aerospace materials. By simulating various environmental conditions from low to high temperatures, this equipment can evaluate the stability, durability, and reliability of products under different temperature conditions.

II. Working Principle

The working principle of the rapid temperature change high and low temperature test chamber is based on the reverse Carnot cycle, which consists of two isothermal processes and two adiabatic processes. The refrigerant is adiabatically compressed to a higher pressure in the compressor, consuming work and raising the exhaust temperature. It then exchanges heat isothermally with the surrounding medium through a condenser, transferring heat to the medium. Next, the refrigerant expands adiabatically through a valve, doing work and lowering the temperature. Finally, it absorbs heat isothermally from a higher-temperature object through an evaporator, reducing the temperature of the cooled object. This cycle repeats continuously to achieve cooling. Additionally, the equipment is equipped with a heating system, which uses heating sources such as electric heaters or heating tubes to rapidly increase the temperature inside the test chamber.

III. Technical Features

Wide Temperature Range: Capable of rapidly simulating various environmental conditions from low to high temperatures, typically ranging from -70°C to 150°C or even wider.

Rapid Temperature Change: Features the ability to quickly heat and cool, with heating and cooling rates ranging from 5°C/min to 30°C/min, adjustable according to user requirements.

Precise Control: Through advanced temperature control systems and sensors, it can precisely control the environmental temperature, with temperature control accuracy up to ±0.5°C, meeting various testing needs.

High Temperature Uniformity: Optimized airflow design ensures uniform temperature distribution inside the chamber, with temperature uniformity typically within ±1.5°C. For example, the following specifications can be referenced:

Internal Chamber Dimensions: 500*750*600mm      (W* H *D)

External Dimensions (approx.): 1050*1850*1100 mm  (W* H *D)

Opening 1: Located on the left side of the equipment, diameter 200mm*1 for installing the customer's glass, with a slot for securing the glass; the center of the opening is 1150mm from the ground, equipped with a heating defrosting device.

Opening 2: Diameter 50mm, located below the 200mm diameter opening on the left side for wiring purposes.

Glass Door: Two openings of 130mm diameter on the glass door.
