GB/T 37292-2019Air enthalpy testing facility for test—General technical requirements (English PDF)

GB/T 37292-2019 is the English-translated version of 试验用空气焓值法试验装置 通用技术要求.

GB/T 37292-2019 sets general technical requirements for the test air enthalpy test device, which the text calls the test device.

Clause 1 states that the standard specifies the working conditions, product classification, general requirements, inspection methods, inspection rules and marking, packaging and transportation of the device, that it applies to air enthalpy test devices used in the territory of the People's Republic of China for the test of cooling or heating capacity of all air conditioners (machines) and air heat exchangers, and that other similar test devices may also use it for reference.

The contents list clause 4 working conditions, with subclauses on the working environment conditions of the instrumentation in the test device, the power supply conditions of the test equipment and other conditions, clause 5 product categories, clause 6 general requirements, split into system composition, technical requirements and calculation method, clause 7 test method, clause 8 inspection rules and clause 9 marking, packaging and shipping.

Clause 7 runs from appearance and the weather resistance test of components and materials through the measurement system accuracy test and the control accuracy test to inspections of the test room, the air temperature and humidity regulator, the air volume measuring device and the air temperature and humidity, air pressure and electrical parameter measurement systems, and ends with security.

Seven appendices follow, the normative ones covering the placement position of the air sampling device, the calculation of air volume, the physical properties of wet air, the inspection of the electrothermal calibration device of the air enthalpy test device and the symbol definitions used in the formulas, the informative ones the air conditioner (machine) connection duct styles and the sealing test method for the airflow measuring device, and a reference list closes the document.

Clause 2 cites GB/T 191-2008, GB 2894-2008, GB/T 4798.1-2005, GB 7231-2003, GB/T 7725-2004, GB/T 15479-1995, GB/T 17611-1998, GB 29481-2013 and GB/T 29823-2013, while clause 3 applies the terms and definitions of GB/T 7725-2004, GB/T 17611-1998 and GB/T 29823-2013, repeating some of them, and shows definitions of air conditioner (air) and air heat exchanger before the draft on the page breaks off.

The introduction states that, apart from GB/T 29823-2013, no uniform specifications had been formed for the technical indicators and calculation methods of the device, which is why its technical requirements needed standardizing.

The standard was proposed by the China Machinery Industry Federation and is under the jurisdiction of the National Industrial Process Measurement Control and Automation Standardization Technical Committee (SAC/TC124). It was issued on 2019-03-25 and has applied since 2019-10-01.
