Space Cooling » CHCP systems

Introduction

Distributed CHCP is an emerging solution to provide space heating, sanitary hot water and space cooling separately or simultaneously. The combination of a CHP prime mover with a thermally driven chiller can provide and interesting solution to reduce energy consumption and CO₂ emissions, but the higher upfront capital costs mean that care must be taken in the design of the system and distributed CHCP will not make sense for all residential households. Distributed CHP will make the most sense in large multi-family dwellings, where the combination of sanitary hot water, cooling and space heating. Primary energy savings depend on the efficiency of electricity generation system, but typically range from 10% to 35%. Payback times can vary between 7 years and 13 years in cases where the systems are economic.
