Cooling and Refrigeration Systems
PaceControls technology carves out the most efficient slice of compressor run time.
Cooling efficiency in an air-conditioning or refrigeration unit doesn’t depend on the amount of time the compressor is running. Efficiency depends on the density of the refrigerant that is being moved per unit of time. In most cooling systems, the compressor keeps running until the thermostat indicates that the set point has been reached.
With PaceControls technology, cooling continues as the refrigerant continues to change state, and the circulating fans distribute the cooled air–even when the compressor is not running.
Reduced compressor running time means:
- Less icing on evaporation coils, providing more efficient heat transfer
- Less energy used in a defrost cycle
- Lower average compressor stator winding temperatures, which can lead to increased compressor life
Cooling and Refrigeration Applications
- Compressor-driven cooling equipment with thermal expansion valves and a capacity of five tons and larger (60,000 Btu/hour)
- Smaller compressor-driven systems with higher loads and/or higher energy costs
- Non-centrifugal chillers up to 100 tons, controls permitting
PaceControls technology has successfully improved the energy efficiency of the following types of cooling equipment:
- Package air-conditioning/heating units
- Split system air-conditioning/heating units
- Heat pumps (air source)
- Heat pumps (water source)
- Chiller units (non-centrifugal)
- Walk-in coolers and freezers
- Refrigeration racks
- Refrigerated display cases
- Refrigerated warehouses
- Industrial process cooling equipment
