BS EN 14511-3:2007 Air conditioners, liquid chilling packages and heat pumps with electrical driven compressors for space heating and cooling. Test methods
BS EN 14511-3 specifies the test methods for the rating and performance of various types of space heaters and coolers. Specifically, air and water-cooled air conditioners, liquid chilling packages, air-to-air, water-to-air, air-to-water and water-to-water heat pumps with electrically driven compressors are covered.
BS EN 14511-3 also specifies the method of testing and reporting for heat recovery capacities, system reduced capacities and the capacity of individual indoor units of multisplit systems, where applicable.
BS EN 14511-3 applies to:
• factory-made units that can be ducted
• factory-made liquid chilling packages with integral condensers or for use with remote condensers.
• factory-made units of either fixed capacity or variable capacity by any means
• packaged units, single split and multisplit systems
• single duct and double duct units
• air-to-air air conditioners which evaporate the condensate on the condenser side.
BS EN 14511-3 is primarily intended for water and brine chilling packages but can be used for other liquid subject to agreement.
BS EN 14511-3 does not apply to units using transcritical cycles, e.g. with CO2 as refrigerant. Installations used for heating and/or cooling of industrial processes are not within the scope of this standard. It does not apply to units that have their condensers cooled by air and by the evaporation of external additional water.
