Sizing CCHP Systems for Variable and Non-coincident Loads, Part 2: Operating Strategies

ABSTRACT One serious challenge to the implementation of combined cooling, heating and power (CCHP) systems is matching and sizing the system to strongly and frequently varying load conditions. Previous works, part 1 of this work in particular, have proven that while CCHPs have significant cost and performance advantages over traditional single-cycle systems, inadequate strategies, failure to address system flexibilities to accommodate load variations in particular, seem to have negatively impacted this promising technology. This paper discusses some techniques that can improve system flexibility for variable and non-coincident loads.
