The working cycle of the refrigeration device should adopt a vapor compression refrigeration cycle and a heat pump and other similar cycles. This standard does not apply to the following pressure vessels: 1. Vessels with an inner diameter (for vessels with non-circular cross-sections, the maximum geometric size of the inner boundary of the section) less than 150mm or with a volume less than 0.03m^3; 2. Exchangers, cooling pipes, plate heat exchangers, etc.; 3. Generators for direct-fired absorption refrigeration devices. Containers or pressure components whose structural dimensions cannot be determined by this standard are allowed to use the following Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of NB/T 47012-2020_English be delivered?Answer: Upon your order, we will start to translate NB/T 47012-2020_English as soon as possible, and keep you informed of the progress.
