A new HVAC system is proposed and studied. The plant is equipped with
a reciprocating i.c. gas engine which produces electric energy with he
at recovery from the jacket water heat and the exhaust. The electric e
nergy serves the lighting and emf for the building and individual room
reversible air-water heat pumps that mainly satisfy sensible cooling
and a fraction of the winter heating load. An open-cycle absorption sy
stem, which treats the primary air, meets the summer latent load and y
ear round ventilation requirements. In winter, the system operates as
an open-cycle heat pump. The regeneration of the sorbent is obtained b
y the i.c. engine heat recovery. The proposed system is analysed by co
mparing its performance with a traditional plant, both in summer and w
inter mode. Copyright (C) 1996 Elsevier Science Ltd
