IEA48

Reversible air conditioning

 Period

-

 Context

Air conditioning in office buildings is an increasingly important component of energy consumption in buildings. This function is currently mostly provided by a refrigerating machine with refrigerant compression. Most of these cooling systems (air conditioning) generate heat (refrigerant condensation) at the same time, which is rarely used. Moreover, these systems are technically quite easy to reverse: in this case the refrigeration machine is transformed into a heat pump.

 Objectives

The international IEA48 project aims to study, in tertiary buildings, the potential energy savings resulting either from heat recovery at condenser level or from the reversibility of refrigeration machines. These possibilities are studied in terms of potential savings but also in terms of technical means.
