COOLING TOWERS: OPERATION AND MAINTENANCE

COOLING TOWERS: OPERATION AND MAINTENANCE

Aug 01, 2020 Evaporative (or cooling) towers are able to best realise the water/air heat exchange process: evaporation is forced through the use of simple, effective components which normally require minimum maintenance. To better understand how heat dissipation occurs, two concepts need to be introduced. Sensible heat.

Installation Operation and Maintenance Manual

Installation Operation and Maintenance Manual

Magnitude chillers are equipped with one or two compressors operating in parallel with a single evaporator and single condenser. The chillers use refrigerant R-134a that operates at a positive pressure over the entire operation range, so no purge system is required. The controls are pre-wired, adjusted and tested.

How do absorption chillers work? -

How do absorption chillers work? -

The principle behind an absorption process is to separate and recombine to fluids (refrigerant and absorbent) to create a cooling effect. Usually, absorption chillers are either NH 3 -H 2 0 (ammonia-water) cycle or LiBr (Lithium bromide) cycle. In the first cycle, water acts as the absorbent while ammonia water solution acts as the refrigerant.
