National and industry standards for heating radiators

  • 2022-01-03 14:53

The heating method with the heating radiator at the end is the mainstream heating method in my country. The heating radiator is currently in accordance with national and industry standards, including such as HJ508-2009 "Environmental Labeling Product Technical Requirements heating radiator" and the "Steel-Aluminum Composite Radiator" being drafted , "Copper and Aluminum Composite Radiator", "Composite heating radiator", etc.

The national industry standards for heating radiators stipulate the classification and basic parameters, performance requirements, inspection methods and rules, signs, packaging, transportation, storage, services, etc. of various heating radiators.
A,  National and industry standards for heating radiators-product standards
my country’s standards are divided into national standards (GB), industry standards, local standards and corporate standards. At present, the national, industry and enterprise standards for heating radiators are as follows: 
1. GB/T 13754-2008 "Method for Measuring heat dissipation of heating radiator"
2, GB 19913--2005 cast iron heating radiator
4, JG 143 heating radiator, aluminum column airfoil radiator
5, JG 220-2007 copper-aluminum composite column airfoil radiator
6, JG 221-2007 copper tube convection radiator
7, JG 232-2007 bathroom heating radiator
9, JG/T 148-2002 steel tube radiator
11, HJ508-2009 "Technical Requirements for Environmental Labeling Products heating radiators"
12.Q/HDPJQ013-2011 "heating radiator Steel Aluminum Composite Radiator"
13.Q/HDPJQ014-2012 "Steel heating radiator"
B, The relevant national standards of the heating radiator industry
1 heat dissipation test standard
GB/T 13754-2008 "Method for Measuring heat dissipation of heating radiator"
 It stipulates that the standard working condition of China's heating radiator is T=64.5 Degree, that is, the inlet water is 95 Degree, the return water is 70 Degree, and the indoor temperature is 18 Degree.
2 National Water Quality Standard for Heating radiator heating System
GB/T29044-2012 "Water Quality of Heating and Air-Conditioning System"
The PH value and oxygen content of the heating system of the heating radiator are clearly stipulated, and the PH value of 9.5-12 is required to prevent the heating radiator and heating pipe network from reducing their service life due to corrosion. The standard requires that the dissolved oxygen limit in the water of the heating radiator heating system is not higher than 0.1mg/L.
3 heating radiator design standard' target='_blank'>heating radiator design standard
1) GB50736-2012 "Code for Design of Heating, Ventilation and Air Conditioning of Civil Buildings"
There are general provisions on heating and heating radiators manufacturer
 In areas where the annual average daily temperature is less than or equal to 50°C and the number of days is greater than or equal to 90 days, centralized heating should be adopted. (Note: Mainly refers to the area north of my country's Qinling-Huaihe line)
 In areas that meet one of the following conditions, buildings such as kindergartens, nursing homes, primary and secondary schools, and medical institutions should adopt centralized heating.
The number of days when the average daily temperature is stable lower than or equal to 5 Degreeis 60-89 days;
The number of days where the cumulative annual average temperature is less than or equal to 5°C is less than 60 days, but the number of days where the cumulative annual average temperature is less than or equal to 8°C is greater than or equal to 75 days.
 When selecting a heating radiator, the following requirements should be met:
---- The working pressure of the heating radiator should meet the working pressure of the system and comply with the current national product standards;
----Civil buildings should adopt heating radiators with beautiful appearance and easy to clean;
----Industrial buildings that emit dust or require high dust-proof requirements, heating radiators that are easy to clean should be used;
----Industrial buildings with corrosive gas or rooms with high relative humidity, corrosion-resistant heating radiators should be used;
----When a heating radiator is used, a closed system should be adopted and meet the product's water quality requirements. The heating system should be filled with water for maintenance during non-heating seasons; the steam heating system should not adopt steel column, plate and flat heating radiators such as pipes;
----When aluminum heating radiators are used, internal anti-corrosion aluminum heating radiators should be selected and meet the product's water quality requirements;
----The hot water heating system with heat meter and thermostatic valve should not use heating radiator such as cast iron with sticky sand in the water flow channel.
The heating radiator of the kindergarten must be concealed or covered with a protective cover.
2) JGJ 26-2010 "Design Standard for Energy Efficiency of Residential Buildings in Severe Cold and Cold Areas"
3) Article 7.2.3 of "Technical Regulations for Heat Supply Metering" JGJ173-2009 stipulates that the radiator should not be installed with a heating cover.
4) Article 5.2.4 of the "Design Standard for Energy Conservation of Public Buildings" GB50189-2005 stipulates that the radiator should be installed on an open surface, and the outer surface of the radiator should be painted with non-metallic paint.
5) The "Code for Residential Design" GB50096-1999 stipulates that residential radiators should be compact, easy to clean, and have a service life of no less than steel pipes. cast iron radiators fully meet this requirement.
4 Energy-saving acceptance specifications for heating radiators
 GB 50411 "Code for Acceptance of Construction Quality of Building Energy-saving Engineering---Heating Energy-saving Engineering"
Revision draft of the national standard "Code for Acceptance of Construction Quality of Energy-saving Buildings" GB50411
 When the radiators and thermal insulation materials used in the heating and energy-saving projects enter the site, the following performance should be re-inspected, and the re-inspection should be witness sampling and inspection: the unit heat dissipation capacity of the radiator and the metal heat intensity;
 Inspection method: check the re-inspection report.
 Inspection quantity: if the number of radiators of the same manufacturer, the same material, and the same specification, if the number is 500 groups or less, 2 groups shall be randomly inspected; if the number is more than 500 groups, 3 groups shall be randomly inspected. For multiple unit projects (group buildings) of the same construction unit constructed by the same construction unit, when the same manufacturer, the same material, and the same specification radiators are used, the combined calculation shall be based on the random inspection of 3 groups for every 50,000 m2 building; less than 5 When 10,000 m2, 3 groups are randomly inspected.
