SASO published MEPS requirements for Commercial Air Conditioners

SASO published MEPS requirements for Commercial Air Conditioners

The Saudi Standards, Metrology and Quality (SASO) published a new standard of Commercial Air Conditioners – Minimum Energy Performance Requirements and Testing Requirements, SASO 2874:2016 on Mar. 3rd, 2017. Different MEPS requirements are defined for different types of air conditioners. The standard will enter into force six months from the date of publication.

1. Scope

This Standard specifies the Minimum Energy Performance Standard (MEPS) and testing requirements for air conditioners of the following main product categories:

  • Electrically operated air conditioners
  • Condensing units
  • Chillers
  • Absorption Chillers
  • Electrically operated variable refrigerant flow (VRF) air conditioners
  • Close control air conditioners and condensing units serving computer rooms

It shall apply to air conditioners designed to operate in AC single-phase circuits of 220V or 230V, or designed for dual voltage or voltage range including these values, and three-phase circuits of 380V or 400v with a frequency of 60 Hz. Air-conditioners having special voltages, not under the scope of this standard, shall be subject to SASO approval, in condition that they do not exceed 660V. For water-cooled chillers voltages up to 15000v are included.

2. Testing conditions

  • For water cooled system, the testing conditions are presented in the relevant standards for each type of air-conditioners.
  • For room computers and data processing air conditioners testing conditions are defined in SASO 2874.
  • For all other units shall be tested under the T1 and T3 testing conditions at full load and maximum operating testing at 52°C.

3. Registration

  1. Path A- Product using the AHRI certification program
    The product/products submitted for registration shall present a valid AHRI certification covering the model/models registered. If a product fails AHRI certification or if its certification is removed, the product registration will be automatically canceled.
    Operability at 52°C is verified by test or based on self-declaration.
  2. Path B- Product using test report as evidence of the declared performances
    1. A test report, per product, from an accredited laboratory shall be presented for registration.
      This test report shall include results for cooling capacity and EER ant T1 and T3.
      Operability at 52°C is verified by test or based on self-declaration.
    2. Test for one sample is sufficient.
    3. The tolerances of tested effective power input, cooling capacity and EER (or NsensCOP) shall be no more than 5%.  Tested EER (or NsensCOP) shall be no less than MEPS.

4. Market surveillance

  1. Using Path A for registration
    SASO will check periodically if the AHRI certification is still valid.
  2. Using Path B for registration
    The product shall be tested based on the corresponding standards as registered through SASO system. One sample will be tested.  The tolerances of tested effective power input, cooling capacity and EER (or NsensCOP) shall be no more than 5%.  Tested EER (or NsensCOP) shall be no less than MEPS.

沙特發佈商用空調能效標準

2017年3月3日,SASO發佈了商用空調能效標準SASO 2874:2016,針對不同類型的空調提出了不同的MEPS要求。該標準自發佈之日起六個月開始強制實施。

一、 產品範圍:

  1. 電動單元空調(SASO 2663包括的空調除外);
  2. 冷凝機組;
  3. 冷水機組;
  4. 吸收式冷水機組;
  5. 電動變製冷劑(VRF)空調;
  6. 機房精密空調及冷凝機組。

水冷冷水機組除外的產品為單相220V/60Hz或230V/60Hz,雙電壓或電壓範圍則需要涵蓋上述電壓。三相則為380V/60Hz或400V/60Hz。不在這份標準範圍下的特殊電壓產品,如果不超過660V的話需經SASO批准。水冷冷水機組則是15000V以下。

二、 測試工況:

  1. 水冷系統按照相應的測試標準;
  2. 機房精密空調按照SASO 2874規定的工況;
  3. 其它空調為T1工況、T3工況及52℃最大運行工況,MEPS基於T1工況。

三、 產品註冊

  1. 使用AHRI認證程式
    1. 持有效的AHRI認證進行註冊,若產品產品未通過AHRI認證或產品被移除認證則註冊自動註銷。52℃最大運行工況通過測試或自我宣稱。
  2. 測試報告
    1. 憑授權測試實驗室測試報告進行註冊,報告需包含T1及T3工況的製冷能力及EER。52℃最大運行工況通過測試或自我宣稱。
    2. 一個測試樣板。
    3. 測試功耗、製冷能力及能效比與宣稱值偏差不超過5%,測試能效比要大於等於MEPS。

四、 市場監督

  1. 使用AHRI認證程式註冊
    對這類產品,SASO檢查AHRI認證是否有效。
  2. 使用測試報告註冊
    SASO按照註冊時使用的測試標準進行市場抽查測試,測試一個樣板。測試功耗、製冷能力及能效比與宣稱值偏差不超過5%,測試能效比要大於等於MEPS。
