民用灶具的热效率是评价其性能优劣的主要指标。由于所采用的测试方法不同,测试条件不同,对同一灶具会得出不同的热效率值。这样一来,不仅无法对灶具作出准确评价,而且对不同的灶具亦无法进行比较。为此,需要一个统一的测试方法和标准。在国外,各个国家都有统一的测定方法和标准。在国内,目前还没有统一起来。我们希望尽快有我国统一的测试方法和标准。
The thermal efficiency of civilian cooking appliances is the main indicator for evaluating the performance of the cooking appliances. Due to the different test methods used and the test conditions are different, different thermal efficiency values can be obtained for the same cooktop. As a result, it is not only impossible to make an accurate assessment of the cooking appliances, but also to compare different cooking appliances. For this purpose, a unified test method and standard are needed. In foreign countries, all countries have uniform measurement methods and standards. At home, it is not yet unified. We hope to have our unified testing methods and standards as soon as possible.
