Scope

GB/T 37819-2019 is the English-translated version of 低温余热双循环发电装置.

GB/T 37819-2019 specifies the terms and definitions, types and basic parameters, requirements, test methods and inspection rules for low-temperature waste heat dual-cycle power generation equipment, together with marking, packaging, transport and storage.

Clause 1 limits the standard to equipment that recovers waste heat in the temperature range of 60 degrees C to 200 degrees C, which the text thereafter calls simply the device.

The contents list eight clauses: Scope, Normative references, Terms and Definitions, type and basic parameters, Requirements, Test method, Inspection rules, and Marking, packaging, transportation and storage.

Clause 3 carries a single entry, 3.1, which defines the unit as a device made up of an evaporator, an expander, a generator, a condenser, a working fluid pump and a grid-connected device, able to convert low-temperature heat energy into electrical energy, with a schematic diagram given in Figure 1.

Clause 2 cites fifteen documents, among them GB/T 156, GB/T 755, GB/T 2820.3, GB/T 4208, GB 4706.1-2005, GB/T 11348.3, GB/T 18430.1-2007, GB/T 20136-2006 and JB/T 4330-1999.

The standard was proposed by the National Development and Reform Commission of the People's Republic of China and is under the jurisdiction of the National Environmental Protection Industry Standardization Technical Committee (SAC/TC275).

The draft shown on the source page breaks off inside clause 3, so clauses 4 to 8 are known only by their titles. It was issued on 2019-08-30 and has applied since 2020-03-01.
