refroidissement à eau
An indoor liquid chiller that transfers condenser heat to a cooling-water loop for efficient, stable chilled-water production at medium and large loads.
- Stable Indoor Operation
- High Heat-Exchanger Efficiency
- Screw or Centrifugal Compression
- Cooling-Water Heat Rejection
Introduction de produit
The water-cooled chiller uses a refrigerant evaporator to cool the cleanroom chilled-water loop and a separate condenser to transfer heat into cooling-tower or process water. Because condensing temperature is controlled by water rather than hot roof air, the unit can achieve stable performance and compact indoor placement at large capacity. Screw compressors provide robust staged or variable capacity, while centrifugal machines suit still larger duty. Water flow, fouling allowance and treatment are coordinated for both heat exchangers.
Key Features
Shell-and-tube heat exchangers provide serviceable water circuits for medium and large plant capacities.
Variable compressor capacity follows cleanroom load without relying only on compressor cycling.
Indoor installation protects refrigeration equipment from outdoor weather and airborne debris.
Préoccupations du client produit
A water-cooled chiller depends on both the chilled-water and condenser-water systems; poor flow or fouling on either side reduces plant performance.
Scale on condenser tubes raises refrigerant pressure and compressor power.Water treatment, strainers and serviceable tube bundles limit and remove fouling.
Low evaporator flow risks freezing and unstable leaving-water temperature.Flow proof, minimum-flow control and staged capacity protect the evaporator.
A single large chiller operates inefficiently during night or low-production load.Variable capacity and multi-chiller sequencing keep active equipment within an efficient range.
Plant-room pipe forces distort heat-exchanger nozzles.Independent pipe supports and flexible connectors isolate external loads from the chiller.
