Scope

Scope: This document specifies the technical requirements (including material and dimensional requirements, low-carbon and environmental protection requirements, and high-efficiency heat exchange performance requirements) for low-carbon and high-efficiency refrigerator heat exchangers, as well as testing methods (including carbon emission accounting methods and heat exchange performance testing methods), inspection rules, packaging, transportation, etc. This document applies to low-carbon and high-efficiency finned heat exchangers used in household refrigerators, freezers/refrigerators, water dispensers, wine cabinets, ice makers, and other products. Main technical content: 5. Technical requirements 5.1 Appearance The appearance of the heat exchanger shall meet the following requirements: a) The fins shall be free from deformation, scratches, cracks, misalignment, or burrs, and ensure their parallelity. b) The surface of the aluminum tube shall be free from pinholes, cracks, peeling, or bubbles, and the tube mouth shall be free from unevenness or burrs. c) The side plates shall be marked with the manufacturer's name and date (which can be done with adhesive labels). d) The surface of the heat-shrinkable sleeve shall be free from bulges or gaps. The welding points shall not be incomplete or overheated. e) For refrigeration and temperature-controlled chamber heat exchangers: The surface of the parts shall be treated with varnish, and the varnish film shall be smooth, free from peeling, cracks, or unevenness. It is allowed for the varnish to flow on the bottom of the fins, but the residual height of the varnish on the bottom of the fins shall not exceed 5mm (calculated from the visible discoloration). f) For copper-aluminum welding points, they shall be painted or wrapped in heat-shrinkable sleeves with adhesive. There shall be no observable or palpable water on the inner surface of the heat-shrinkable sleeve or on the corresponding metal tube.
