Modular absorption chiller in slab construction

摘要

Intermittent ammonia water absorption chiller, designed as a stack of vertical plates, with bypass, temperature control and heat recovery, consisting of two generators (13, 15), three absorbers (17, 18, 20), an evaporator (25), a condenser (23 ), two controlled by control valves (M3, M5) solution-vapor-emitting (on the one hand 9A, 9B, 9C, 9D, 8A, M3, V1, V2 on the other hand 11A, 11B, 11C, 11D, 10A, M5, V3, V4) the construction of the plate stack next to the thin two-dimensional mold plates for generators, absorber, condenser and evaporator also thick mold plates with three-dimensional elements for containers, pumps and distribution channels use, and this plate stack consists of three surface-connected sub-stacks, of which the outer (1A, 1B ) Containers, pumps and distribution channels, while the middle stack (2) with the generators, absorber, condenser and evaporator is narrower, so that on the side of the gesa The plate stack has a recessed vertical longitudinal channel in which the control elements (6) of the machine are mounted.
