Heat and Cold Temperature Air Conditioning Chamber

LIB Industry's Heat and Cold Temperature Air Conditioning Chamber uses a precision temperature control system, refrigeration unit, electric heating system, and optimized air circulation to maintain a consistent test environment. Programmable controllers allow users to set multiple temperature stages, dwell times, and automatic cycles for unattended testing. The SUS304 stainless steel interior provides corrosion resistance and easy cleaning, while the insulated chamber structure reduces heat loss and improves energy efficiency. Adjustable shelves, cable holes, observation windows, and sample fixtures can also be customized according to different test requirements.

Core Parameters of the Heat and Cold Temperature Air Conditioning Chamber

Working Principle of the Heat and Cold Temperature Air Conditioning Chamber 

1. Precise High- and Low-Temperature Control: The chamber combines an electric heating system with mechanical refrigeration to reproduce controlled hot and cold environments. Depending on the selected configuration, temperatures can be controlled from approximately –40°C to +150°C, allowing users to simulate conditions encountered during transportation, storage, operation, and outdoor exposure.

2. Uniform Air Circulation: A forced-air circulation system continuously distributes conditioned air throughout the working space. This reduces temperature gradients and helps prevent localized hot or cold areas, ensuring that samples receive a consistent thermal environment during long-duration and cyclic tests.

3. Programmable Temperature Cycling: The controller can store multiple test programs with different temperature setpoints and holding times. For example, a cycle may alternate between –40°C and +85°C, remain at each temperature for several hours, and automatically repeat for dozens or hundreds of cycles. This is useful for detecting thermal expansion, contraction, cracking, electrical instability, and material degradation.

4. Fast Temperature Transition: The chamber can be configured with different heating and cooling rates according to test requirements. Typical heating performance can reach around 3°C/min, while cooling performance is commonly around 1°C/min, depending on chamber size, temperature range, and test load. Faster temperature-change configurations are also available for demanding thermal cycling applications.

5. Reliable Long-Term Testing: For extended aging and reliability studies, the chamber maintains the programmed temperature continuously for hours or days. Typical conditions may include +85°C for 500–1,000 hours, –40°C for several hours, or repeated high/low-temperature cycles. Safety functions such as over-temperature protection, compressor protection, leakage protection, and emergency shutdown help protect both equipment and test samples.

6. Flexible Laboratory Configuration: The equipment can be customized with different working volumes, shelves, test holes, viewing windows, and electrical interfaces. These options make it suitable for small electronic components as well as larger automotive assemblies and industrial products.

Typical Applications and Test Standards of the Heat and Cold Temperature Air Conditioning Chamber  

This equipmentsupports testing across a wide range of industries. In electronics and semiconductors, it is used for burn-in, thermal cycling, and reliability testing referenced in JESD22 and the IEC 60068 series, typically cycling between –40°C and 125°C. Automotive electronics testing often follows ISO 16750 or GB/T 2423, exposing components to ranges from –40°C to 105°C to simulate under-hood or cabin conditions. Aerospace and defense programs frequently reference MIL-STD-810, covering high-altitude cold down to –55°C and desert heat up to 71°C. Battery and energy-storage testing commonly follows UL 1642 or IEC 62133, with thermal abuse tests run between –20°C and 60°C. Packaging and materials evaluation under ASTM D4332 typically uses conditioning cycles around 23°C to 60°C with controlled humidity. Pharmaceutical and cosmetic stability testing, guided by ICH Q1A, often holds samples at 25°C/60% RH or 40°C/75% RH for extended periods. Across all these applications, conditions are logged continuously so results remain traceable and repeatable.

FAQs on the Heat and Cold Temperature Air Conditioning Chamber   

Q1: Can the equipment be configured for faster ramp rates than the standard specification? 

Yes. While the standard configuration achieves 3°C/min heating and 1°C/min cooling, high-speed versions reaching 10–15°C/min or more can be built for applications such as thermal shock testing.

Q2: Is remote monitoring available for long-duration tests? 

Yes, the controller supports data logging and can be connected to a network for remote status checks, with optional alarm notifications sent by email or SMS when a test deviates from its set parameters.

Q3: Can the equipment be customized for oversized or irregular samples? 

Yes, equipment dimensions, shelf configurations, and cable holes can all be adjusted at the design stage to accommodate larger assemblies, additional wiring, or special fixtures.
