Introduction

In order to standardize the energy efficiency of household gas instant water heaters and gas heating water heaters that implement energy efficiency label management The measurement and inspection work is revised according to the requirements of JJF 1261.1-2017 "Measurement and Inspection Rules for Energy Efficiency of Energy-Using Products" this specification. This specification replaces JJF 1261.9-2013.Compared with JJF 1261.9-2013, except for editorial modifications, the main The technical changes are as follows. ---The name of the specification is determined by the "Household Gas Instant Water Heater and Gas Heating Water Heater Energy Efficiency Marking Measurement Regulations" "Regulations" was changed to "Rules for Measuring and Testing Energy Efficiency of Household Gas Instant Water Heaters and Gas Heating Water Heaters"; ---The scope of application is from "household gas instant water heaters (including condensing water heaters) with heat load not greater than 70kW and gas-fired heating and water heaters” to “household gas-fired household Gas instant water heater (including condensing household gas instant water heater) and gas heating water heater (including condensing gas heating bath Dual-purpose furnace" (see Chapter 1); --- Added GB 25034-2010, CJ/T 336-2010, CJ/T 395-2012 three reference documents (see Chapter 2); --- Added "condensing domestic gas instant water heater", "condensing gas heating and bath dual-purpose furnace" and "rated Heat load hot water efficiency", "Rated heat load heating efficiency" and "Energy efficiency grade" (see Chapter 3); ---In addition to the test method in accordance with the requirements of GB 6932-2001 "Household Gas Instant Water Heater", there are also Added the relevant content of three documents according to GB 25034-2010, CJ/T 336-2010, and CJ/T 395-2012 conduct; --- The minimum permissible energy efficiency index for each level in Table 1 is changed from the original fixed one for rated load and partial heat load The single value of thermal efficiency is changed to define the lower limit of the larger value and the lower limit of the smaller value of these two thermal efficiency values; --- Added Appendix D "Correction of Condensing Water Heater Efficiency and Condensing Furnace Low Water Temperature Test Efficiency". The previous releases of this specification are as follows. ---JJF 1261.9-2013. Household gas instant water heater and gas heating water heater Energy Efficiency Measurement and Testing Rules

1 Scope

This specification stipulates the domestic gas instant hot water with a rated heat load not greater than 70kW that only uses gas as energy Heaters (including condensing household gas instant water heaters, hereinafter referred to as "gas water heaters") and gas heating water heaters (including Condensing gas heating and bath dual-purpose furnace, hereinafter referred to as "gas heating furnace") energy efficiency measurement requirements, measurement testing Procedures, measurement and testing methods, evaluation criteria for measurement and testing results, and testing reports. This specification is applicable to the supervision and testing of the energy efficiency measurement of gas water heaters and gas heating furnaces. Commissioned testing can refer to This specification is carried out. Units that produce and sell gas water heaters and gas heating furnaces can also refer to this specification detection. This specification does not apply to gas volumetric water heaters. The gas referred to in this specification shall comply with the provisions of GB/T 13611. The gas water heaters and gas heating furnaces to be tested should be products that have passed the self-inspection by the producer, or the products purchased by the seller. Export and sales of goods.
