Microchannel Heat Exchanger
The Microchannel Heat Exchanger (MCHE) generally delivers higher heat-transfer efficiency than traditional exchangers (such as shell-and-tube or finned-tube types) thanks to its unique design and structural optimization. The following analyzes the efficiency of microchannel heat exchangers: High heat-transfer area density: Microchannel heat exchangers use tiny channels (typically 0.5–3 mm in diameter), significantly increasing the heat-transfer […]
Do Fresh-Air Systems Include Heating and Cooling Functions?
Whether a fresh-air system includes heating and cooling functions depends on the specific equipment type and configuration. The following briefly explains fresh-air system functions: Basic fresh-air system: The main function of a standard fresh-air system is to introduce outdoor fresh air, expel indoor stale air, and reduce energy loss through heat recovery (such as total […]
