睇完呢個冷氣機能源標籤有D唔明

因為有新/舊制,應該係新制更加嚴格,咁好多機舊制係1級,咁新制變咗2-5級,好正常呀。
但有D機舊制係2級,新制反而變咗做1級,真係有D唔明點解

會唔會測錯評錯????????更新反^_^


其實個標籤點定義點測試有無講？

CSPF=5.3263新舊制都應該係1級。最差嘅解釋係手民之誤。或者仲有其他因素決定評級未定。
但新舊制應該只係改咗評級方式，測試條件好似未改過。真係要問下EMSD至知。

利申：電已郵。

終於有回音，EMSD回覆，原來計算方式都有更改：  

Thanks for your enquiry. Having checked our record, the air-conditioner (Brand: MITSUBISHI, Model: SRKM50IN/SRCM50IN-E) is a Grade 2 listed model before the upgrading of energy efficiency standards and it was then upgraded to Grade 1 to the new standard.

Having implemented the upgrading of energy efficiency standard, some room air conditioners in Grade 1 to Grade 3 of the past standard are reclassified into Grade 1 to Grade 5. Since the calculation method to define the energy efficiency grade were changed, the grading in the past standard will be reclassified, i.e. it may be upgraded or downgraded depending on the characteristics of the room air-conditioners. We found that most split type room air conditioner in variable capacity can achieve a higher energy efficiency grade after the upgrading of energy efficiency standard, and it is the reason the air-conditioner you mentioned, which is a variable split type room air conditioner, can be upgraded to Grade 1 from its original grading of Grade 2.

For the new calculation method that defines the energy efficiency grades, you can refer to Section 7.6 in the ‘Code of Practice on Energy Labelling of Products 2014’. You can find the document in the link below:

    用官腔答,答咗即係冇答

都有睇過佢個計算方法,大致上係只測量35度(室外)full load同half load (變頻機only)個perfromance,其他好多野都係假設之後計出黎(由24度到36度),跟住個結果就分級咁解。

再睇番上期選擇,個half load EER最高嗰部就係CSPF最高,但half load EER一般catalog 唔會標出黎,而亦由於half load EER比full load EER高,所以變頻機比定頻機慳電,仲有個測試只計制冷量,唔會理個風速大少,所以風速大會"覺得"涼D,但嘈D。
