Main components of the constant temperature and humidity test chamber:
Thermostat system: Includes heating and cooling sections. Heating is achieved through the air heating unit, while cooling is regulated by the refrigeration solenoid valve.
Humidification system: Composed of water tank heating elements, etc., it increases the humidity inside the chamber by evaporating the water in the water tank.
Control system: Temperature and humidity sensors collect data, which is transmitted to the temperature and humidity (micro-information processor) for editing and processing, and then the temperature and humidity control instructions are issued.
Air circulation system: Rotating fans installed at the top of the chamber, which discharge air into the chamber to achieve gas circulation and balance the temperature and humidity inside the chamber.If you need more information about the models of our testing equipment. Please contact me.
Working principle: When adjusting the temperature, the temperature sensor collects data, which is regulated by the temperature controller (micro-information processor), and the air heating unit is turned on to increase the temperature or the refrigeration solenoid valve is adjusted to lower the temperature; when adjusting the humidity, the humidity sensor collects data, which is regulated by the humidity controller (micro-information processor), and the water tank heating element is turned on to increase the humidity or the refrigeration solenoid valve is adjusted to dehumidify, thereby achieving the purpose of controlling the required temperature and humidity.

The temperature-humidity-vibration combined test chamber is a testing equipment capable of simulating the combined environment of temperature, humidity changes and vibration. It is mainly provided for scientific research and production units in fields such as aerospace, aviation, petroleum, chemical industry, electronics, and communications to offer testing conditions.
The working principle of the low-pressure temperature and humidity test chamber is based on thermodynamics and heat conduction principles. It simulates different environments by controlling heating (heating up), cooling (refrigeration), and exhaust (vacuuming) systems.
The working principle of the low-pressure test chamber is based on the physical law that atmospheric pressure decreases with increasing altitude. Inside the equipment, components such as vacuum pumps and vacuum valves can effectively regulate the pressure inside the chamber to reach the preset low-pressure environment. In addition to the environmental conditions. Air is extracted or the pressure inside the chamber is changed by using a compressor to simulate different altitudes. The pressure control inside the test chamber is carried out, and the low-pressure test chamber usually also has the function of adjusting temperature and humidity parameters to simulate more complex environmental conditions.If you need more information about the models of our testing equipment.
The thermal vacuum test equipment is mainly composed of a vacuum container, a heat sink, a vacuum pumping system, a temperature regulation system for both high and low temperatures, an installation base for the test piece, a detection and measurement system, a control and data acquisition and processing system, etc.
The vacuum level of the spacecraft's environment is 13.3 - 13.3 x 10-10 millibars (10-4 - 10-14 millimeters of mercury). From the perspective of heat transfer, a vacuum level of 13.3 millibars is sufficient to meet the requirements for simulating the thermal physical properties of the spacecraft. To save test costs, the vacuum level typically used in thermal vacuum tests is usually set to be better than 13.3 millibars. To evaluate and study the dry friction, cold welding performance of certain moving parts and extension mechanisms, as well as the sublimation, weight loss, aging and other effects of materials under vacuum conditions, tests need to be conducted under higher vacuum levels and other combinations of space environment factors. At this time, a vacuum level of 13.3 x 10-1 - 13.3 x 10-10 millibars (10-5 - 10-14 millimeters of mercury) can be obtained in small and medium-sized space simulators.

The high acceleration life test (HALT) equipment meets the basic capabilities of both temperature tests and vibration tests, and can also conduct combined tests of temperature and vibration simultaneously.
Vibration test technical parameters: 6-degree-of-freedom (three-axis six degrees of freedom) repetitive shock vibration function and quasi-random vibration function 2) Bandwidth for vibration energy distribution: 10Hz to 10000Hz;
3) The maximum vibration output amplitude of the platform is not less than 35 Grms (when the platform is not loaded). Temperature test parameters: The temperature test is conducted to perform rapid temperature change tests on the product, which requires the air circulation system of the HALT test equipment to generate sufficient wind speed to achieve the rapid temperature change effect of the product and maintain stable temperature. The temperature test parameters of the equipment are as follows: Rapid temperature change capability (maximum temperature change rate not less than 45â??/min); Temperature range: -80â?? to +170â??.If you need more information about the models of our testing equipment.

Temperature data collection system
During the high acceleration life test (HALT), it is necessary to collect and monitor the response data of the test samples, including temperature information, vibration information, and performance parameters, etc. Equip a temperature collection device to collect and store the data information from the temperature sensor, in order to verify whether the temperature stress actually applied during the test process has been imposed on the product. The temperature collection can also be achieved through the temperature collection system of the HALT test equipment itself, or by using other multi-channel temperature collection systems. The thermocouples in the temperature collection device must have stable temperature sensing characteristics within the temperature variation range of (-100â?? - +200â??).
