<p>消费者委员会发现，13 款贴有香港最高能效标签的空调型号的制冷效率差异可达 33%。消费者委员会于周四发布了 13 款 1.5 马力变频分体空调的测试结果，发现标有 1 级标签的产品在节能性能上存在 “显著差异”，并呼吁改善评级标准。消费者委员会首席执行官阿莱娜·岑兆辉表示：“除了 1 级能效标签，消费者还可以查看标签上显示的年能耗，以比较节能性能。” 在这 13 款型号中，有七款为反向循环空调，价格从 8,380 港元到 19,610 港元（1,070 美元到 2,504 美元），其余为仅制冷的型号，价格在 4,890 港元到 7,880 港元之间。委员会与电机机械服务署委托进行的测试发现，制冷季节性能因子（CSPF）测量制冷能效，范围从 5.057 到 7.510，数值越高表示效率越好。委员会表示：“尽管所有型号均被评为 1 级，但制冷能效的差异显著。” 根据 CSPF 值，最节能的型号每年可节省多达 33% 的能源，相比之下，效率最低的型号则节能效果较差。最节能的型号来自三菱重工，而效率最低的型号则来自 TOSOT。然而，测试的型号比五年前类似测试中的型号效率高出约 11%。在加热性能方面，最节能的型号每年也能比效率最低的型号多节省 14% 的电力。委员会还发现，尽管有两个型号符合国际标准，但其声称的制冷能力未达标，而一个型号的声称加热能力也未达标。委员会指出，目前分体空调的制冷性能能效标准自 2014 年以来一直未变。“委员会认为，进一步加强空调的评级标准有助于更好地反映产品之间实际的能效差异，以帮助消费者做出明智的选择，并鼓励供应商推出更节能的产品，从而促进可持续消费。” 服务署表示，今年将开始与行业进行技术讨论，以提高分体式和窗式空调的能效标准。它补充说，持续监测产品能效，并定期审查强制标签计划下的评级标准，以鼓励进口商引入更高效的型号。同时，售后条款差异很大。近一半的型号仅提供一年的整机保修，而只有一款提供三年的全面保障。两个型号没有提供延长保修选项。2026 年初，关于空调的投诉激增，委员会在年初的前四个月收到了 66 起投诉，超过去年同期记录的 29 起。自 2023 年以来，委员会共收到 1,200 起关于空调的投诉。</p>

<p>香港消费者委员会发现，13 款顶级空调型号的制冷效率差异高达 33%。尽管所有型号均获得了一级能效标签，但在节能性能上仍存在显著差异。来自三菱重工的最有效型号每年可节省比来自 TOSOT 的最低效型号多 33% 的能源。委员会呼吁改善评级标准，以更好地反映实际能效，并注意到消费者对空调的投诉有所增加</p>

<p>The cooling efficiency of 13 air conditioner models bearing Hong Kong’s top energy label can vary by up to 33 per cent, the consumer watchdog has found. The Consumer Council on Thursday released test results for 13 models of 1.5-horsepower inverter split-type air conditioners, finding “substantial differences” in energy-saving performance among units with a Grade 1 label and calling for improved grading standards. “Apart from the Grade 1 energy label, [consumers] can also check the annual energy consumption shown on the labels to compare energy-saving performance,” said Alaina Shum Jiu-fai, chief executive of the watchdog. Among the 13 models, seven were reverse-cycle air conditioners priced from HK$8,380 to HK$19,610 (US$1,070 to US$2,504), while the rest were cooling-only units priced between HK$4,890 and HK$7,880. The tests, commissioned by the council and the Electrical and Mechanical Services Department, found that the Cooling Seasonal Performance Factor (CSPF), which measures cooling energy efficiency, ranged from 5.057 to 7.510, with higher values indicating better efficiency. “Despite all models being rated Grade 1, the differences in cooling energy efficiency were significant,” the council said. “Based on CSPF values, the most energy-efficient model could save up to 33 per cent more energy annually than the least efficient one.” The most efficient model is from Mitsubishi Heavy Industries, while the least efficient is from TOSOT. However, the tested models were about 11 per cent more efficient than those in a similar test conducted five years ago. In terms of heating performance, the most efficient model could also save 14 per cent more electricity annually than the least efficient one. The council also found that two models fell short of their claimed cooling capacity, despite meeting international standards, while one model did not meet its claimed heating capacity. The watchdog noted that the current energy efficiency standards for split-type air conditioners’ cooling performance had been in place since 2014. “The council opines that there is room to further strengthen the grading standards of air conditioners to better reflect actual energy efficiency differences among products to help consumers make informed choices and encourage suppliers to introduce more energy-efficient products, thereby promoting sustainable consumption,” it said. The services department said it would begin technical discussions with industry this year to raise energy-efficiency standards for both split‑type and window‑type air conditioners. It added that it continuously monitored product energy efficiency and periodically reviewed grading standards under the mandatory labelling scheme to encourage importers to bring in more efficient models. Meanwhile, after-sales terms varied widely. Nearly half of the models came with only a one-year full-machine warranty, while just one offered three years of full coverage. Two models did not offer extended warranty options. Complaints about air conditioners have surged in early 2026, with the council receiving 66 cases in the first four months of the year, more than double the 29 recorded in the same period last year. The council has received 1,200 complaints about air conditioners since 2023.</p>
