EA Credit 4: Enhanced Refrigerant Management
2 Points

Intent
To reduce ozone depletion and support early compliance with the Montreal Protocol while minimizing direct
contributions to climate change.

Requirements
OPTION 1
Do not use refrigerants.
OR
OPTION 2
Select refrigerants and heating, ventilation, air conditioning and refrigeration (HVAC&R) equipment that
minimize or eliminate the emission of compounds that contribute to ozone depletion and climate change. The
base building HVAC&R equipment must comply with the following formula, which sets a maximum threshold for the combined contributions to ozone depletion and global warming potential:

Small HVAC units (defined as containing less than 0.5 pounds of refrigerant) and other equipment, such as
standard refrigerators, small water coolers and any other cooling equipment that contains less than 0.5 pounds of refrigerant, are not considered part of the base building system and are not subject to the requirements of this credit.
Do not operate or install fire suppression systems that contain ozone-depleting substances such as CFCs,
hydrochlorofluorocarbons (HCFCs) or halons.

Potential Technologies & Strategies
Design and operate the facility without mechanical cooling and refrigeration equipment. Where mechanical cooling is used, utilize base building HVAC&R systems for the refrigeration cycle that minimize direct impact on ozone depletion and global climate change. Select HVAC&R equipment with reduced refrigerant charge and increased equipment life. Maintain equipment to prevent leakage of refrigerant to the atmosphere. Use fire suppression systems that do not contain HCFCs or halons.

EA C4: 增强制冷剂管理
2分

目的
减少臭氧层破坏，先期符合蒙特利尔议定书的规定，最小化产生气候变化作用。

要求
选项1
不使用制冷剂
或者
选项2
选用的暖通空调设备最小化或不排放破坏臭氧或引起气候变化的物质。基准建筑的暖通空调设
备必须符合以下公式，这里设定了产生臭氧破坏和全球变暖的限值：
小型暖通空调设备(指制冷剂小于0.5磅)和其它设备，如冷冻机、小型冷水机等其它小于0.5
磅制冷剂填充量的设备，在本项目计算中不含入。
不要安装或使用含有破坏臭氧的消防系统，如：佛里昂、卤代佛里昂、哈龙等。

技术措施和策略
建筑在设计和运行时不使用机械制冷设备。如需使用机械制冷设备，则采用最小破坏臭氧或增
进地球变暖的暖通空调设备。维护设备防止泄漏制冷剂。采用无HCFC或哈龙的消防系统。
