Energy storage system chiller selection criteria

How do I choose a new chiller?

In the past, one of the key market pressures when selecting a new chiller was footprint, today however, its energy efficiency. Undertaking an energy analysis audit of your existing refrigeration equipment and comparing the consumption to a new unit with the latest technology will help you understand how much energy you could be saving.

What are the minimum energy performance standards for industrial cooling equipment?

New industrial cooling equipment must meet new minimum energy performance standards (MEPS). Process chillers must meet Seasonal Energy Performance Ratio (SEPR) metrics and comfort chillers must meet new Seasonal Energy Efficiency Ratio (SEER) values.

How much chiller capacity do I Need?

As you can see, the full 100-ton chiller capacity is needed for only two hours in the cooling cycle. For the other eight hours, less than the total chiller capacity is required. If you count the tinted squares, you will total 75, each representing 10 ton-hours.

Do different chillers have different areas of strength?

Different chiller designs have different areas of strength, although some are inherently more effi-cient in terms of energy units consumed per unit of chilled water produced. Table 2 compares the energy efficiency of the different chiller types. 2 A lower number indicates a more efficient chiller.

Is your chiller required for manufacturing process cooling?

If your chiller is required for manufacturing process cooling, it’s even more important as an incorrect specification could affect the quality of your product, your environmental obligations and the operation and maintenance costs significantly. Energy efficiency regulations – the EcoDesign Directive

What is an ice bank® cool storage system?

An Ice Bank® Cool Storage System, commonly called Thermal Energy Storage, is a technology which shifts electric load to of-peak hours which will not only significantly lower energy and demand charges during the air conditioning season, but can also lower total energy usage (kWh) as well.
