ENERGY SAVING Product Offering COMPRESSOR MARKETING OPPORTUNITIES
CURRENT CONDITIONS Facility owner/managers are faced with reducing their operating costs. There are many different directions they can choose and making the best business decision can be a challenge as: Equipment ages- efficiency decrease Utility cost increase Repair costs increase Operating budgets change Refrigerant availability /cost changes due to phase out Comfort issues
CHOICES Option 1 Replace the entire system with new equipment Pros: New equipment can reduce repair costs New equipment will contain new environmentally friendly refrigerant New equipment can be more efficient Comfort issues can improve
CHOICES Option 1 Cons: $ Capital funds availability System down time
CHOICES Option 2 Life Extension Project 1.Survey the building and existing equipment condition 2.Identify key pieces of equipment that have reached the end of it’s service life like: Compressors Motors Contactors Controllers Dampers Economizer controls Wear items Heat exchangers Pumps Piping
CHOICES Option 2 Make needed repairs Replace wear items Clean existing system components Re-commission the system
ADVANTAGES Option 2 Allows the ability to select components that will reduce energy use Upgrade the system vs. replacing the entire system Less cost than replacing
OPPORTUNITIES Option 2 Utilize the local utility company to assist in funding the project by: Performing a quick analysis of the building's mechanical system Obtain the past 12 months (or more) of utility bills Qualify the opportunity by using the data collected Contacting an energy engineer approved by the utility company Determine the energy savings Calculate the utility’s possible rebate
EQUIPMENT SELECTION COMPRESSORS Fixed-speed compressors found in traditional HVAC systems operate at two states, off or 100% on. This wastes energy during part load conditions which is where most systems operate 99% of the time. This includes 1, 2 or 3 stage compressors that cannot compare to the full range variable capacity of a VFD rotary screw chiller today. Most chillers installed 20 years ago were rated near 1.3 kW/ton performance which is a 8 EER. This was the standard for the chillers at that time. MCS developed a system realizing reductions in Kw/ton down to 0.4 at part load conditions. That equates to 30 EER. This could bring your energy savings up to 26%.
HOW DO WE DO IT? …with tested improvements found using VFD technology on rotary screw compressors controlled by energy performance software using components that MCS has developed.
SOLUTION The MCS Energy Performance System reacts quickly to capacity changes and ramp up faster than fixed speed compressor systems Also eliminates the high demand created in across the line or even part start motors. This performance based technology coupled with energy efficient software using electronic expansion valves can change a failing inefficient system nightmare into a cost saving solution without the huge capital investment of replacing the entire system. The best part of this equation is not only will the MCS Energy Performance System reduce operating costs, going directly to the customer’s bottom line but the local utility will help pay for the installation with incentives. This permits a quicker return on investment.
FIRST STEP Identify locations with equipment approaching the end of it’s service life Perform a quick analysis of the building's mechanical system Obtain the past 12 months (or more) of utility bills Qualify the opportunity by using the data collected Contact an energy engineer approved by the utility company Determine the energy savings Calculate the utility’s possible rebate Sell to the customer using the ROI based on the energy savings
