This standard specifies the energy efficiency testing and comprehensive evaluation methods for industrial heat exchangers. This standard applies to industrial shell and tube heat exchangers, spiral plate heat exchangers and plate heat exchangers. The term heat exchanger in this standard includes heat exchangers (no phase change), condensers (with phase change on the hot side and no phase change on the cold side) and evaporators (with phase change on the cold side and no phase change on the hot side). . Heat exchangers that fall within the scope of the regulatory catalog of the "Special Equipment Safety Supervision Regulations" should comply with the relevant requirements of the "Regulations" during testing. Other industrial heat exchangers can refer to this standard.
