低泄漏空气侧经济器的产品设计要点

Key Design Points of Ultra-low Leak Airside Economizer

低泄漏空气侧经济器是北美地区风冷产品(如屋顶机)上的一种新风选项,产品设计主要涉及风阀装置、风性能、制冷可靠性、传感器位置、防水验证和合规认证。文中介绍了产品背景、结构组成和工作原理;分析了与整机制冷系统相关的设计要点;说明了测试方法和合规认证要求,并总结了经验教训。

The low leak airside economizer is a kind of fresh air option for the North America air-cooling products(such as rooftop units). The product design mainly includes damper equipment, airflow performance, refrigeration reliability, sensor position, waterproof verification and compliance certification. This paper introduces the product background, structure composition and working principle, analyzes the design key points, test methods and compliance certification requirements regard to the unit refrigeration system, and summarizes the lesson learned.
