TCVN 7830: 2015, Energy efficiency of non-ducted air conditioners

Last updated: 23 October 2019

TCVN 7830: 2015 replaces TCVN 7830: 2012

This standard applies to air conditioners without air ducts using compressor-type motors n and condenser cooled non-empty , a cluster or two clusters, with or without inverters (hereafter referred to as equipment) having an rated cooling capacity of up to 12 000 W (41 000 BTU / h). This standard also applies to air conditioners with air ducts of a nominal refrigeration capacity of less than 8 000 W and is designed to work at small external static pressures n 25 Pa. This standard does not apply to water-cooled, air-cooled, portable, floor, ceiling, air-conditioned more than two clusters or if the air conditioners use three-phase electricity.
