FAQs:
  • What is the total efficiency of this 8KW CHP unit?
    The 3 Phase Residential CHP achieves an impressive overall efficiency of 90.9%, combining 25.6% electrical efficiency and 65.3% thermal efficiency from heat recovery.
  • From which sources does the CHP recover heat?
    This cogeneration unit recovers waste heat from four key sources: the engine jacket water, the alternator cooling water, the exhaust system, and the exhaust manifold, maximizing energy utilization.
  • What are the key specifications of the engine used in this CHP?
    The CHP is powered by a SP9EW engine, which is a 4-cylinder, 4-stroke, 16-valve, water-cooled engine with a displacement of 1.5L, operating at 1500 RPM with an 11:1 compression ratio.
  • Is this unit suitable for grid connection?
    Yes, this 8KW 10KVA CHP is designed for grid-on cogeneration, meaning it can synchronize with and supply power to the electrical grid while also providing thermal energy.
