District energy efficiency improvement with absorption cooling: the Hungarian experience.

Author(s) : EMHO L.

Summary

It is well known that with combined heat and power (cogeneration) systems one can reach 80 to 90% joint energy production efficiency, while it is only 30 to 40% for separated electrical power and 80 to 90% for heating-only systems. A basic requirement is that the ratio between the two energy forms must be within certain limits. Average electrical power consumption varies within a 30 to 50% wide range, while it does within 200 to 300%, in the temperate zone, for heating, during a full year of operation. Summer (low heating load) period is specially critical for load balance. This balance and the total efficiency can be improved by utilizing absorption cooling. Cooling is otherwise a requirement for summer operation of buildings. Basic considerations and case studies are discussed.
