22 / TRANSPORT REFRIGERATION UNIT EMISSIONS REQUIREMENTS
冷机 TRU 环保要求Transport refrigeration unit emissions requirements
冷藏运输要核对的不只是牵引车，柴油冷机本身也有独立的环保管理事项。下面用临时换挂一辆冷藏拖车的情景，说明接单前应查哪些官方项目资料。Refrigerated transport requires checks beyond the tractor: the diesel refrigeration unit has its own emissions program. A last-minute trailer swap illustrates which official program records to check before accepting the equipment.

CARB TRU 项目所述柴油运输制冷／加热机组，包括卡车箱体、半挂车、集装箱和铁路车辆中的相应设备。本页为项目入门，不覆盖食品卫生、温控合同或完整 TRU 技术达标判定。Diesel transport refrigeration/heating units described by CARB, including equipment on truck vans, semitrailers, containers and railcars. This introduction does not cover food-safety rules, temperature contracts or a complete technical TRU compliance determination.
先弄清这几条要求Start with these requirements
先辨认冷机，而不只检查车头Identify the refrigeration unit, not just the tractor
- 具体要求What the rule requires
- CARB 将 TRU 描述为使用柴油内燃机、为运输易腐产品提供制冷或加热的系统。因此核对冷藏运输环保状态时，应单独识别所用机组和设备类型；不能由牵引车检测合格推导该冷机也合格。CARB describes TRUs as diesel-internal-combustion-engine systems that refrigerate or heat perishable products in transport. Identify the unit and equipment type separately when checking emissions status; a tractor’s passing test does not establish the refrigeration unit’s compliance.
Transport Refrigeration Units (TRU) are refrigeration systems powered by diesel internal combustion engines designed to refrigerate or heat perishable products that are transported in various containers, including truck vans, semi-truck trailers, shipping containers, and railcars.

费用、登记和达标分别查官方记录Check fees, registration and compliance separately
- 具体要求What the rule requires
- CARB 项目页载明，2022 年修订于 2022 年 10 月 1 日生效，涉及 TRU 运营费和适用设施登记费；2025 年 SB 153 授予相关收费权限。具体谁缴费、何时缴、设备是否达标，应使用项目页链接的现行指引、登记及合规查询核对，本页不补造统一收费金额或全部设备的淘汰日期。CARB states that the 2022 amendments took effect October 1, 2022 and address TRU operating fees and applicable facility-registration fees; SB 153 in 2025 authorized related fee collection. Use the linked current guidance, registration and compliance tools to establish who owes what, when, and whether a unit complies. This page does not invent a universal fee or retirement date for every unit.
On February 24, 2022, CARB approved amendments (2022 Amendments) to the Transport Refrigeration Unit Air Toxic Control Measure (TRU ATCM) for In-Use Diesel-Fueled TRUs (Title 13 CCR §§ 2477–2477.24), effective October 1, 2022. The 2022 Amendments require TRU and facility owners or owner/operators to pay operating and registration fees, respectively. On September 17, 2025 Governor Newsom signed Senate Bill (SB) 153 granting CARB authority to impose fees on entities regulated under the 2022 Amendments to the TRU ATCM.
Guidance documents and answers to frequently asked questions are now available to assist stakeholders with TRU operating and applicable facility registration fee requirements.

教学例子WORKED EXAMPLE
临时换挂冷藏拖车A last-minute refrigerated-trailer swap
教学示例：调度给司机换了一辆冷藏拖车，司机只收到牵引车的环保检测证明。Illustrative example: dispatch substitutes a refrigerated trailer, but the driver receives only the tractor’s emissions-test proof.
索取机组资料Obtain unit information
请设备提供方说明冷机型号、登记及合规状态，按 CARB 的相应查询核对；这里是接单核对建议。Ask the equipment provider for unit type, registration and compliance status and check the relevant CARB resources; this is an operational checking recommendation.
分开记录Keep the checks distinct
把牵引车和冷机的确认资料分别记录，不用一份车头证明覆盖全部设备。Record tractor and refrigeration-unit checks separately instead of using a tractor document for all equipment.
冷机是独立核对对象；不确定设备类别和官方状态前，不作“一定合规”的判断。Treat the refrigeration unit as a separate check; do not declare compliance before its category and official status are established.
实际工作中，最容易弄错的地方Common mistakes in day-to-day work
常见误会：冷机规则就是食品温度规则Misconception: TRU rules are food-temperature rules
CARB TRU 页面讨论空气污染管理。货物温度、卫生和合同交付条件属于其他核对事项，本页不把这些责任混成一个许可。CARB’s TRU page addresses air pollution. Cargo temperature, sanitation and contractual delivery conditions require separate checks and are not combined into one authorization here.
