How to improve chiller efficiency and plant performance?

Every manufacturing organization have a requirement of efficient chillers, Chillers are the single energy-consuming component in the majority of companies and can frequently use more than 50% of the electricity. According to the Department of Energy, chillers can waste up to 30% more energy due to inefficiency. Inefficiently operating chillers also reduce equipment reliability, lengthen maintenance intervals, and limit equipment lifespan. The efficiency can be significantly affected by even a small drop in chiller performance. For example, every degree Celsius increase in condenser water temperature above the full load design can reduce chiller performance by 1% to 2%. In extreme circumstances, a malfunctioning or neglected water treatment scheme can cause a reduction in efficiency of 10% to 35% or more.

Contrary to common perception, operating a chiller at full design load and achieving the design kW/ton does not always imply that the chiller is operating at its most efficient level. The largest tonnage may be produced by a chiller while using the fewest kilowatts. Based on design, the majority of chillers operate at their most efficient levels when they are operating at roughly 70–75 percent load and with the lowest entering condenser water temperature (ECWT). The facility can choose the most energy-efficient chiller configurations by knowing a chiller’s efficiency as well as the effects of load and ECWT.

• Energy savings:
  

  Chillers are one of the largest consumers of energy in commercial and industrial buildings. Improving their efficiency can result in significant energy savings, which can translate into lower utility bills and reduced operating costs.

• Environmental impact:
  

  Reducing the energy consumption of chillers can also help to reduce greenhouse gas emissions, which can have a positive impact on the environment.

• Improved comfort:
  

  Efficient chillers can help maintain a comfortable temperature in buildings, which can improve occupant comfort and productivity.

• Extended equipment life:
  

  Improving chiller efficiency can also help to extend the life of the equipment, reducing maintenance and replacement costs.

There are several professionals who can help improve the efficiency of a chiller, depending on the specific circumstances and issues.

Energy Management Consultant or Energy auditors: Energy Management Consultant specialize in evaluating a building’s energy usage and recommending ways to improve efficiency. They can easily identify opportunities to reduce the energy consumption of the chiller, such as improving insulation or optimizing the chiller’s operating schedule.

Chiller Optimization: An energy management consultant can evaluate the performance of the chiller and identify areas of improvement. They can adjust the chiller controls and operating schedules to optimize its performance and reduce energy consumption.

Energy Audits:An energy management consultant can perform an energy audit to identify opportunities to improve the efficiency of the chiller and other HVAC systems. The audit may involve assessing the building envelope, lighting, and other systems to identify potential energy-saving measures.

Maintenance and Repairs:An energy management consultant can recommend and implement maintenance and repair strategies that can improve chiller efficiency. They can identify issues such as refrigerant leaks, dirty coils, and worn belts that can cause the chiller to consume more energy than necessary.

System Upgrades:An energy management consultant can recommend upgrades to the chiller system that can improve its efficiency. For example, they may recommend replacing outdated equipment with newer, more efficient models or installing variable speed drives to reduce energy consumption.

Staff Training:An energy management consultant can provide training to chiller operators and maintenance staff to help them identify and correct issues that can impact chiller efficiency. This can help to ensure that the chiller is operating at optimal efficiency over the long term.

An energy management consultant can help to improve chiller efficiency by providing expertise and guidance on optimization strategies, maintenance and repairs, system upgrades, and staff training. Their expertise can help building owners and operators to reduce energy consumption and costs while improving the performance of their HVAC systems.
