Absorption Chillers and Heat Pumps


Cool. Cap. 527-5064 kW, Double Effect Exhaust Gas

Compared to conventional designs, the YHAU-CE Double-Effect Exhaust Gas driven absorption chiller uses an innovative two-step evaporator and absorber cycle that splits the absorption process into two steps, similar to how a series counter-flow arrangement splits the work between two chillers. This, along with the parallel flow cycle, enables lower lithiumbromide solution concentrations, which reduces crystallization risk, reduces the potential for corrosion and improves efficiency, in conjunction with these advanced components:

• Low- and high-temperature solution plate heat exchangers that optimize efficiency by enabling effective heat transfer between the diluted and the concentrated lithium-bromide solutions.

• Variable-frequency drive (VFD) solution pump that provides superior part-load performance to reduce exhaust gas consumption verses constant speed pumps.
