York Chiller at Morrisons

Are you looking to improve Chiller efficiency?

Your Chiller will undoubtably consume a substantial part of your company utility bills. So, what steps can you take to make considerable energy savings and make your chiller cooling system more efficient?

Your Chiller will undoubtably consume a substantial part of your company utility bills. So, what steps can you take to make considerable energy savings and make your chiller cooling system more efficient?

Chiller systems will operate more efficiently through proper ongoing specialist maintenance. Most of our clients understand this and have adopted a monthly chiller maintenance and support plan as part of their day-to-day location best practices as early warning signs that allow you to take action before any problem gets worse. Here are two of the most common best practices that maximise chiller efficiency:

Monitor refrigerant charge

As well as a legal requirement to ensure zero refrigerant leakage, a chiller’s cooling effectiveness requires accurate refrigerant levels within the system. Establishing correct refrigerant charge can massively improve process chiller efficiency by reducing cooling costs by as much as 15%.

Compressors are nearly always the single most intensive energy consumer in the system, and often in the entire site, Introducing head pressure control with a low condensing temperature in cooler weather will provide a typical saving between 2% and 4% of compressor power for every 1°C reduction in condensing temperature.

Maintaining condenser cleanliness

This will provide up to 10% energy saving from cleaning alone and with water cooled condensers any foreign debris such as sand or grit can affect the condenser water loop – in essence, anything that inhibits water flow will negatively impact the operating efficiency of any chiller.

For most of our clients, chillers operate as an integral part of a more complex Process system. Many systems can be relatively simple, but some chillers (such as water cooled chillers) can sometimes be more complex if they are connected to a cooling tower system. Therefore, when BRS assess overall chiller performance for each individual process, we make a complete analysis of total power consumption of the equipment – compressor, pumps, cooling tower fans, etc.

In summary, the evaluation and optimisation of the complete chiller plant must be viewed universally. Adjustments can only be actioned based on precise data and current load profiles Therefore, it is important to closely monitor efficiency to identify any changes in performance and predict improvements that can be made as quickly as possible. Our clients rely on the highly experienced BRS team to meticulously care for and maintain their entire process cooling operations – combining operational efficiency with energy cost savings as part of an ongoing preventative planned maintenance program. 

Most people choose a chiller on the basis of the maximum load and the warmest weather. In these conditions, a chiller may well be quite efficient, but most of the time the load will be lower and the temperature cooler, so part load evaluation needs to be taken into consideration, Why not take a look at our YORK Amichi Inverter chillers available to buy online, or for more information, get in touch with our specialist team today.
