Trigeneration

 

Trigeneration means combined production of power, heat, and cold. Technically, it is a combination of a CHP unit with an absorption cooling unit. The advantage, from the viewpoint of CHP unit operation, it that it allows utilization of heat even during the summer, when  the heating season is over, thus extending the yearly run-time of the CHP unit. 

 

It is just the limited utilization capabilities of CHP unit heat during summer months that often lead to the installation of smaller units than would normally be convenient. Therefore, if we can convert heat into cold, nothing prevents us from running CHP units productively during summer months. The cold air they produce can be used wherever air-conditioning is required - in banks, hotels, shopping and administrative centers, hospitals, sports arenas, etc.  (see the types of TEDOM trigeneration units).
