Central Chillers are used to provide a cooling fluid and heat removal to an entire facility by providing multiple service use points. Central chiller systems offer several disadvantages and advantages for industrial users. Building-wide chiller systems must include high level of monitoring and control capabilities to ensure thermal exchange is optmal for multiple system applications. Advantages include lower costs of installation and maintenance as opposed to multiple dedicated chillers systems.
Central Chillers are available under 10 to over 1000 tons and with operating ranges from as low as -30°F to +65°F or more. Central chillers are typically built manage any industrial process cooling application from chemical processing, injection molding to metal finishing.
Application pecifications considered for central chillers include:
Power source and requirments
Chiller cooling capacity
Evaporator capacity
Condenser capacity
Motor fan type and capacity
Chiller IP rating
Internal piping materials and piping requirements
Type and number of compressors
Number of refridgerant circuits
Chiller coolant requirements
COP (the ratio between the cooling capacity in KW to the energy consumed by the whole chiller in KW) (chiller efficiency).
Control panel features
Process pump specifications
Motor IP rating and pump rating
Control panel features: local control panel, remote control panel, fault indicators, temperature indicators, and pressure indicators
