Save on Energy Costs
Chillers are the single largest energy-using component in most facilities, and can typically consume from 30 to 50% of the electrical cost, depending on operations. Chillers running inefficiently result in substantially higher energy costs, decreased equipment reliability and shortened lifespan. A chiller operating at 70% efficiency can consume approximately 30% more energy to produce the same cooling. The slightest decrease in chiller performance can have a major impact on efficiency. For instance, a 1°F increase in condenser water temperature can decrease chiller efficiency by 2%.
If you take the example in EffTec’s Cost Justification Chart, and a 2,000-ton chiller was running at 70% efficiency and steps were taken to increase the efficiency to 90%, it would save $147,168 per year in energy costs.
Save on Water Costs
EffHVAC calculates water usage, makeup, blowdown, evaporation, cycles of concentration and projected evaporation credits. Immediately justify the cost of blowdown meters and collecting evaporation credit from the city (if available), dramatically lowering your water bill.
Monitor Equipment Performance
By trending data over time and knowing how a chiller is supposed to perform is powerful information. Any variances in these performance trends can identify potential problems so they can be corrected before they become permanent and require major repair.
Troubleshooting and Pinpoint Problems
The EffHVAC Alarms page will identify certain problems immediately and provide extremely detailed troubleshooting tips including what triggered the alarm, the possible cause of the alarm, symptoms of the potential problem, things to check and possible problems that can occur if gone unchecked or uncorrected. EffHVAC chiller alarms and troubleshooting cover every aspect of the chiller system including the evaporator, condenser, tower system and compressor.
Schedule Downtime
Once problems have been identified early, downtime can be scheduled with minimal loss of productivity and associated costs.
Extend Equipment Life
When certain systems start failing it can increase the workloads of other systems down the line. Identifying problems early and correcting them will dramatically extend equipment life.
Use Savings to Justify Expenditures
When chiller efficiency is increased, it creates a savings that can be leveraged into capital improvements that further enhance efficiency, prolong equipment life and reliability, and create additional savings.
Evaluate and Refine Operating Procedures
Taking steps towards creating a world-class facility means creating and refining operating procedures. EffHVAC can be an extremely valuable tool in the process by delivering concrete performance data.
Create Part Load Values
In the past, identifying chiller part load values has been extremely expensive, even thousands of dollars for each part load value identified. With EffHVAC you can immediately and accurately calculate a chiller’s part load values and identify at what settings you get the most tons of cooling for the least amount of money.
Instant Monthly Chiller Service Reports
EffHVAC can create dynamic monthly reports with the click of a button. A step-by-step guide to interpreting the reports ensures you know your chillers performance and how to improve it. Archived reports can be collected to review improvements over time.
Compare Your Chiller Program to Multiple Locations
Create a baseline performance, which allows for consistent improvement throughout your organization.
Calculate the Most Efficient Equipment Configurations
By knowing how equipment is performing and understanding how it is designed to perform, one can create different chiller configurations to maximize the overall plant efficiency.
Forecasting and Budgeting
By trending chiller data and evaluating the EffTec Monthly Reports, you can predict how changes in energy costs, hours of operation and load balances (tons produced) will affect your future costs. This will also help determine the chiller performance so downtime, manpower, parts and repairs can be budgeted.
Increase Property Value
In the arena of investment property, the sale of the facility is anticipated at some point in time. Lower operating costs create a higher net operating income (N.O.I.). Multiply this increase 10 to 12 times when determining the value of the facility. By establishing a world-class energy program and documenting chiller performance brings confidence to buyers and helps justify the highest possible price for the property.
Environmentally Beneficial
Increasing energy efficiency of your equipment decreases the demand on our nations energy requirements, which will reduce the future depletion of our natural resources.
EffHVAC is Easy to Use and Understand
EffHVAC requires no expensive software, no expensive equipment, only an Internet connection. The service is easy to navigate and the reports are comprehensive.
