热效率指标是反映燃气能转化为热能后,能够有效被利用热量的多少,是衡量燃气灶是否节能的一项重要指标。根据国家标准《家用燃气灶具》(GB16410)中的规定:对于台式燃气灶,热效率应大于55%;嵌入式灶,热效率应大于50%。并将热效率指标条款作为强制性条款,热效 Thermal efficiency indicators reflect the gas can be converted into heat, the amount of heat can be effectively used, is a measure of gas stove is an important indicator of energy conservation. According to the national standard “Household Gas Cooker” (GB16410), the regulation: for desktop gas stove, thermal efficiency should be greater than 55%; embedded stove, thermal efficiency should be greater than 50%. And the terms of thermal efficiency indicators as a mandatory clause, thermal efficiency
