On March 28th, YANMAR Energy Systems hosted an open house with a presentation of their Variable Refrigerant Flow (VRF) and Combined Heat and Power (CHP) systems. Miles Johnson, mechanical engineer from CROFT who worked on the design of the YANMAR EVO//CENTER took part in the presentation, showing what benefits you get when using these engine operated, natural gas heating and air system.

YANMAR’s Combined Heat and Power (CHP) system uses an internal combustion engine, powered by clean natural gas or propane, to produce both heat and electric power. The unit efficiently utilizes up to 88% of the fuel burn versus 33% burn rate of conventional, from-the-grid sources.

Using a natural gas-powered engine to drive dual scroll compressors, YANMAR’s Variable Refrigerant Flow (VRF) Heat Pump can maintain powerful heating performance, even with low outdoor temperatures, by capturing heat off the unit’s engine to increase efficiency. Not only do VRF units withstand some of the toughest temperatures, they do it with supreme efficiency. The cost of operating the compressor in our outdoor units is 1/10 the cost of that of a standard electric system, resulting in hundreds to thousands of dollars of savings in electricity costs.
