A-13 Study on the Standardization of Methods to Measure Efficiency of Domestic Gas and Oil Hot Water Heaters by the Usage Mode : Part 3 Basic Concept of Usage Mode Making and Outline of Measurement for Parameter Extraction

Abstract

In this report, the Supplying Hot Water Usage Mode making method when the efficiency of a domestic gas and the oil heater is described. It was discovered that the heat efficiency for instantaneous hot water heaters was affected on a micro level with regards to the amount of continual time used during a single action, the interval between actions, and the number of actions implemented, and hot water accumulators were affected by the time zone distribution for the actions on a micro level, so these different heat efficiency characteristics were taken into account when creating the Usage Mode. Moreover, the outline concerning ten measurement data to contribute to the Usage Mode making was described.
