Empowering Cleaner Energy Decisions


Compressor chillers produce "cold" using a fuel (typically electricity) to drive the cooling system. The energy performance of a compressor cooling system is influenced by a number of factors such as the type of fuel, the chiller capacity and seasonal coefficient of performance (COP) and the type of compressor (e.g. centrifugal, reciprocating, screw or scroll). Other factors include the size and the type of the cooling load (i.e. space and/or process cooling, single or multiple zones, single or multiple buildings). And the energy performance of a district cooling (multiple buildings) system will also be influenced by the design supply and return temperatures, and the distribution line pipe sizing. Refer to the Compressor Cooling System Schematic for more information.

Software & Data
The RETScreen Software Compressor Cooling Model can be used worldwide to evaluate the energy production and savings, costs, emission reductions, financial viability and risk for compressor chiller projects, ranging in size from high efficiency chiller systems in a dairy plant, meat processing plant or restaurant, to processes cooling applications in the petrochemical, automotive or manufacturing sectors. Other compressor cooling energy efficiency measures include improved control strategies to increase the coefficient of performance in supermarkets, as well as in hockey, skating or curling arenas. The software (available in multiple languages) also includes product, project and climate databases, and a detailed user manual.
