BS EN 14511-1:2018

What is BS EN 14511‑1- HVAC with Electrically driven compressors about?  

BS EN 14511 discusses air conditioners, liquid chilling packages, and heat pumps for space heating and cooling and process chillers, HVAC with electrically driven compressors. BS EN 14511‑1 is the first part of BS EN 14511 multi-series and discusses terms and definitions. 

BS EN 14511‑1 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, and 
• Air-to-air air conditioners which can also evaporate the condensate on the condenser side 

Packaged units, single split, and multi split systems are covered by BS EN 14511‑1. Single duct and double duct units are covered by BS EN 14511‑1. In the case of units consisting of several parts, BS EN 14511‑1 applies only to those designed and supplied as a complete package, except for liquid chilling packages with remote condenser. BS EN 14511‑1is primarily intended for water and brine chilling packages but can be used for other liquids subject to agreement. 

Note 1: Part load testing of units is dealt with in EN 14825 

Note 2: All the symbols given in this text are used regardless of the language 

Who is BS EN 14511‑1- HVAC with Electrically driven compressors for? 

BS EN 14511‑1 on air conditioners, liquid chilling packages and heat pumps for space heating and cooling and process chillers, HVAC with electrically driven compressors, is useful for: 

• Air conditioners manufacturers  
• Refrigerators manufacturers  
• Heater manufacturers 
• Compressor manufacturers 
• Quality control personnel 

Why should you use BS EN 14511‑1- HVAC with Electrically driven compressors?  

For the system to operate as effectively as possible, oxygen is transported to the fuel-cell stack in the cathode path via the electric air compressor. The desired quantity of air is extracted from the ambient atmosphere and made available to the stack at the necessary pressure level for generating electricity. 

BS EN 14511‑1 provides you the terms and definitions for the rating and performance of air conditioners, liquid chilling packages, and heat pumps using either air, water, or brine as heat transfer media, with electrically driven compressors when used for space heating and/or cooling 

BS EN 14511‑1 also provides the terms and definitions for the rating and performance of process chillers. BS EN 14511‑1 helps you simply certain phases that help you understand terms and definitions in a simpler way. 

What’s changed since the last update?  

BS EN 14511‑1:2018 supersedes BS EN 14511‑1:2013, which is withdrawn. BS EN 14511‑1:2018 includes an editorial change with respect to BS EN 14511‑1:2013. This is include: 

• Terms and definitions for process chillers have been added
