Chillers typically consume more electricity than any other single energy-consuming device in a large commercial building. A packaged water-cooled chiller produces chilled water for use in your building's air conditioning system and is typically 40 per cent more efficient than air-cooled chillers due to lower condensing temperatures. Upgrading existing equipment with a variable speed drive can also reduce energy consumption in your building significantly.
Provincial environmental legislation designed to eliminate the release of CFCs and HCFCs may prohibit the overhaul or conversion of an existing chiller system. Overhauling an existing chiller with new refrigerant can be costly, making chiller replacement the most economical option for some buildings.
We offer incentives for water-cooled chiller installations for existing buildings and variable speed drive retrofits. Typical projects can save more than $10,000 a year in energy costs.
Integrated Part Load Value (IPLV) is rated in kW/ton. It is the average power input based upon a chiller operating at part loads through a cooling season.
Incentives available for retrofit projects only. The maximum eligible incentive is $250,000 for all electrical measures included in the project.
|Maximum IPLV requirement|
Example: A 550 ton water-cooled chiller with an IPLV of 0.440
kW/ton is installed.
Incentive = (0.51–0.44) x 550 x $450 = $17,325
New chiller IPLV must be less than or equal to the requirement as stated above.
The Manitoba Ozone Depleting Substances and Other Halocarbons Regulation states that as of December 31, 2005, a chiller containing a Class 1 substance (CFC Refrigerant) shall not be overhauled unless it is concurrently converted to use or operate with a substance other than a Class 1 substance.
