Trigeneration is a combination of cogeneration and absorption chilling. The process of cogeneration produces heat and power, however during the summer months the heat generated may not be fully utilised on site. It is during this time that the demand for cooling often reaches its maximum.

The solution is to use the excess heat to operate an absorption chiller which is linked to the cogeneration unit providing air conditioning.

The annual demands for each customer will be different, but the supply can be developed and tailored specifically making the most of the cogeneration unit, in terms of heat and power usage.

In comparison to conventional air conditioning methods, an absorption chiller consumes far less electricity and therefore leads to considerable savings in primary energy consumption.

Absorption chillers are very compact and do not have any moving mechanical parts, maintenance is therefore kept to a minimum providing additional cost savings.

Key Benefits include reduction in primary energy costs, utilisation of excess heat and electrical energy, and reduced chiller life cycle costs.
