Abstract

The present work is aimed at mapping the thermodynamic performance of a dishwasher operating in the so-called ‘Ecomode’, where the heating is provided exclusively by a heat pump, in accordance with the requirements of the IEC 60436 standard. Tests were carried out in a climate chamber that allows strict control of the surrounding air temperature. In addition, an auxiliary rig was built to control the dishwasher water supply temperature. Initially, a test matrix was proposed for screening the appliance performance in a broad envelope of operating conditions for a given washing load. Later, the test matrix was reduced to get the most out of the standardized tests with a minimum set of data. To this end, a simplified mathematical approach was put forward to reduce the experimental data to come out with key system parameters, such as the thermal conductance and capacitance of the washing cabinet, and the seasonal heat pump coefficient of performance (SCOP), which cannot be easily obtained by means of direct measurements.

使用最小数据集评定热泵洗碗机的季节性能系数的程序

目前的工作旨在绘制在所谓的“Ecomode”中运行的洗碗机的热力学性能，其中加热完全由热泵提供，符合IEC 60436标准的要求。测试是在一个可以严格控制周围空气温度的气候室中进行的。此外，还建造了一个辅助装置来控制洗碗机的供水温度。最初，提出了一个测试矩阵，用于在给定洗涤负荷的广泛操作条件下筛选器具性能。然后，对测试矩阵进行简化，以便用最少的数据集从标准化测试中获得最大的收益。为此，提出了一种简化的数学方法，以减少实验数据，得出洗涤柜的导热系数和热容以及季节热泵性能系数（SCOP）等通过直接测量难以获得的关键系统参数。

期刊介绍： The International Journal of Refrigeration is published for the International Institute of Refrigeration (IIR) by Elsevier. It is essential reading for all those wishing to keep abreast of research and industrial news in refrigeration, air conditioning and associated fields. This is particularly important in these times of rapid introduction of alternative refrigerants and the emergence of new technology. The journal has published special issues on alternative refrigerants and novel topics in the field of boiling, condensation, heat pumps, food refrigeration, carbon dioxide, ammonia, hydrocarbons, magnetic refrigeration at room temperature, sorptive cooling, phase change materials and slurries, ejector technology, compressors, and solar cooling. As well as original research papers the International Journal of Refrigeration also includes review articles, papers presented at IIR conferences, short reports and letters describing preliminary results and experimental details, and letters to the Editor on recent areas of discussion and controversy. Other features include forthcoming events, conference reports and book reviews. Papers are published in either English or French with the IIR news section in both languages.
