GB/T 33841.1-2017 is the English-translated version of 制冷系统节能运行规程 第1部分：氨制冷系统.
GB/T 33841.1-2017 is Part 1 of GB/T 33841 and sets out how an ammonia refrigerating system is to be run, adjusted, maintained and managed so that it uses as little energy as possible.
It applies to vapour compression systems with ammonia as refrigerant, whether the cooling is direct or indirect, and systems with other refrigerants may follow it for reference.
It defines refrigeration, cooling capacity, the refrigerating plant as a whole, and thermal insulation. For the energy calculations and for the plant itself it cites GB/T 2589, GB/T 12497, GB/T 12723, GB/T 13462, GB/T 15587, GB 17167, GB/T 18517, GB/T 28009, GB/T 30134 and GB 50072.
