BS EN 328:2014

What is BS EN 328 – Forced convection unit air coolers for refrigeration test about?  

BS EN 328 is a technical specification that is applicable to non-ducted unit air coolers for refrigeration operating: 

• With direct dry expansion of a refrigerant 
• With liquid overfeed by pump circulation of a refrigerant 
• With a liquid 

BS EN 328 specifies uniform methods of performance assessment to test and ascertain the following: 

• Product identification 
• Standard capacity 
• Standard liquid pressure drop 
• Standard refrigerant pressure drop (for operation with liquid overfeed by pump circulation only) 

• Nominal air flow rate 
• Nominal fan power 

Note 1: BS EN 328 does not cover evaluation of conformity. 

Note 2: BS EN 328 is not applicable to air coolers for duct mounting or with natural air convection. 

Note 3: BS EN 328 does not cover technical safety aspects.  

Who is BS EN 328 - Forced convection unit air coolers for refrigeration test for? 

BS EN 328 on forced convection unit air coolers for refrigeration test is useful for: 

• The petroleum oil and gas industry 
• Chemical processing plant 
• The transportation industry 

• Industrial applications like power plant generation, refrigeration 
• Industrial manufacturers 
• Quality assurance management  

Why should you use BS EN 328 - Forced convection unit air coolers for refrigeration test?  

BS EN 328 is one of a series of European Standards dedicated to heat exchangers.  A heat exchanger is a device that transfers heat from one fluid to another. In both cooling and heating processes, heat exchangers are used. The fluids could be separated by a solid wall to keep them from mixing, or they could be in direct touch. It is consequently critical to clean and maintain heat exchangers in order to keep systems working smoothly. Regular maintenance keeps equipment in good operating order and reduces the need for emergency repairs. 

BS EN 328 provides manufacturers with test methods for quality assurance of forced convection unit air coolers for refrigeration so that the air is always fresh and never stale or stuffy, they help to reduce allergies. A portable air cooler can provide that small bit of moisture needed in the air to make your breathing space simpler and more pleasant. These devices are highly suggested for places of excessive heat and low humidity. BS EN 328 helps users with the durability, long service life and reliability of the non-ducted unit air coolers for refrigeration. 

What’s changed since the last update?  

BS EN 328:2014 supersedes EN 328:1999 and EN 328:1999/A1:2002, which is withdrawn. BS EN 328:2014 includes some technical changes with respect to EN 328:1999 and EN 328:1999/A1:2002. These include: 

• Clause 3 “Terms and definitions” is modified 
• The revised standard takes into account the application of CO2
