Combined Heat and Power
Combined heat and power (CHP) is a system where heat, which is usually lost during the electricity generation process, is recovered and used. This results in much overall efficiencies than grid-supplied electricity and, therefore, carbon emissions are usually reduced. In addition, a trigeneration system can convert the waste heat into chilled water for cooling uses with the inclusion of an absorption chiller. In practice, CHP is often associated with issues such as poor demand control, high heat losses, lower plant efficiencies, overheating in flats, high pumping energy, oversized plantrooms and renewable technology integration which can be avoided with robust design, operation and maintenance.
