加拿大标准协会（CSA）和AHAM/DOE冰箱冷冻柜能耗标准的高环境温度旨在补偿门开口和其他热负荷的不足。Meier和Jansky（1993）最近公布的结果表明，标签消耗量比典型现场消耗量高出15%。对传统模型的内部实地研究表明，标签消费预测过高约22%。冰箱冷冻技术评估（RFTA）试验旨在更准确地预测现场消耗量。 该测试将环境温度和湿度、门开度和冷凝控制设置为代表加拿大家庭条件的水平。它还评估了精确定义的车厢额定温度下的消耗量。实验室测试了10种传统的节能生产模式。RFTA结果比标记结果低约30%。类似地，四种创新冰箱冷冻柜模型在现场测试时的平均消耗量也比标签上的低30%。因此，有限测试的结果表明，RFTA测试可能是对现场使用的更准确预测。 建议使用更大的样本进行进一步测试。实验结果还表明，与类似的常规装置相比，一些创新模型可以节省高达50%的能耗。促成这种性能的技术包括双压缩机、更高效的压缩机和风扇电机、关闭状态制冷剂控制阀、模糊逻辑控制和更厚的绝缘层。更大的节约是在有限的生产模式上，这需要额外的生产工程来实现完全的市场化。 关键词:1995年，能源消耗，测试，创新，冰箱，冷冻柜，制冷，节能，准确性，计算，环境温度，湿度，冷凝，加拿大，国内，实验室测试，现场测试，性能测定:研讨会，ASHRAE Trans。1995年，第101卷，第2部分

The high ambient temperature of the Canadian Standards Association (CSA) and the AHAM/DOE Refrigerator-Freezer Energy Consumption Standards is intended to compensate for the lack of door openings and other heat loads. Recently published results by Meier and Jansky (1993) indicate labelled consumption overpredicting typical field consumption by 15%. In-house field studies on conventional models showed labelled consumption overpredicting by about 22%. The Refrigerator-freezer Technology Assessment (RFTA) test was developed to more accurately predict field consumption. This test has ambient temperature and humidity, door openings, and condensation control set at levels intended to typify Canadian household conditions. It also assesses consumption at exactly defined compartment rating temperatures. Ten conventional and energy-efficient production models were laboratory tested. The RFTA results were about 30% lower than labelled. Similarly, the four innovative refrigerator-freezer models, when field tested, also had an average of 30% lower consumption than labelled. Thus, the results of the limited testing suggest that the RFTA test may be a more accurate prediction of field use. Further testing with a larger sample is recommended. Experimental results also indicated that some innovative models could save up to 50% of the energy consumption compared with similar conventional units. The technologies that contributed to this performance included dual compressors, more efficient compressors and fan motors, off-state refrigerant control valve, fuzzy logic control, and thicker insulation. The larger savings were on limited production models, for which additional production engineering is required for full marketability.KEYWORDS: year 1995, energy consumption, testing, innovating, refrigerators, freezers, refrigeration, energy conservation, accuracy, calculating, ambient temperature, humidity, condensation, Canada, domestic, laboratory testing, site testing, performance
