Finned type heat exchangers are important equipment used in room air conditioners whose performance affects the cooling efficiency, heat transfer rate and HVAC systems in general. These devices are widely used in both domestic and commercial air conditioning systems to provide adequate thermal transfer from the refrigerant to the air. Given that these devices work in conditions of constant variation in terms of temperature and pressure, it is vital that manufacturers follow the standard set out in IS 11329:2018 concerning finned type heat exchangers used in room air conditioners.
The main technical aspects specified by the Indian Standard include fin geometry, tube material, brazing, leakage tightness, dimensional parameters, corrosion resistance, and mechanical strength. Conformity to BIS QCO and IS 11329:2018 certification is compulsory for sale on the Indian market. The ISI mark on finned heat exchangers means that the devices meet certain standards of reliability, safety, and performance.
IS 11329:2018 is the Indian Standard which describes the requirements of heat exchangers of finned type in room air-conditioners. This standard guarantees that such components provide effective heat transfer capabilities while ensuring their structural strength through thermal cycles. According to the Indian Standard, finned heat exchangers must be:
It is compulsory for the manufacturers/importers/suppliers who manufacture/furnish/offer finned type heat exchangers in room air conditioners to get BIS Certification as per IS 11329:2018. This would help ensure safe and standardized functioning of the products.
Applicable to:
BIS ISI certification of finned heat exchangers according to IS 11329:2018 ensures that these heat exchangers fulfill all important aspects of their performance needed in air conditioners.
In order to ensure the dependable working of finned type heat exchangers in room air conditioners, the Bureau of Indian Standards has set certain basic requirements in the standards laid down under IS 11329:2018. The standard assures the reliability of finned type heat exchangers as these will work stably with consistent performance and will give cool output under any kind of continuous thermal cycling, humidity and HVAC operation conditions.
The BIS test parameters for finned type heat exchangers in room air conditioners are as follows:
The BIS certification procedure checks the compliance of finned type heat exchanger used for room air conditioning in accordance with IS 11329:2018 standard before their marketing in India. The procedure is regulated by the Bureau of Indian Standards and involves the following steps:
BIS certification for Finned Type Heat Exchangers under IS 11329:2018 ensures that the component meets the required performance, safety, and durability standards for use in Room Air Conditioners. It guarantees thermal efficiency, corrosion resistance, and quality, thereby improving the overall performance of the air conditioning system. By obtaining BIS certification, manufacturers demonstrate their commitment to high-quality standards, ensuring their products are reliable, efficient, and safe for consumers.
