InRoom Chilled Water Cooling System The APC ACPCW40-150 is a perimeter chilled water cooling unit for medium to large data centers. InRoom Chilled Water systems are available in a packaged fan-coil design. Room air is recirculated through the cooling coil, which transfers the heat load directly into the chilled water ring main. Water flow rate is regulated by a 2- or 3-way valve controlled by the controller microprocessor. Cooling towers are used as a source of heat rejection and can be used to serve multiple indoor units. Towers utilizing outdoor air require water treatment. - System used with a cooling tower or other source of water.
- Factory sealed and tested system.
- Eliminates the need for field refrigerant piping
 Chilled Water Cooling System
Efficiency and Reliability The use of energy efficient, direct drive fans along with fewer moving internal parts eliminate most potentials for failure. Scroll compressor technology provides unparalleled efficiency and constant, reliable operation with an ability to withstand liquid refrigerant slugging' which is a major cause of compressor failure. Refrigeration System and Compressor The refrigeration system operates under a master controller for greater efficiency and accuracy. Suction and discharge pressures are monitored and electronically controlled. The scroll compressors are designed for year-round operation with a 15-year life expectancy. The controller microprocessor provides real-time suction and discharge pressure readings reported by transducers installed on the refrigeration system. For compressor protection, the InRoom precision air conditioner utilizes charge isolation and crank case heaters during off cycles. This eliminates the threat of liquid refrigerant migration that could lead to compressor slugging and lubrication issues.  A look inside the APC ACPCW40-150 InRoom Chilled Water unit

The APC ACPCW40-150 offers many benefits: Availability: - Direct drive motors- Stress on bearings is nearly eliminated, increasing useful life. Allows integral fan/motor assembly to be factory balanced, which lowers vibration and expedites startup.
- Steam humidifier- Humidity is managed through a self-contained steam canister humidifier for maximum efficiency and ease of maintenance. The pure-steam canister maintains consistent capacity output, and requires very little scheduled maintenance.
Total Cost of Ownership: - Variable speed fans- Variable speed fans reduce energy consumption during off-peak cooling periods.
- Electric Reheat- Prevents overcooling during dehumidification.
Serviceability : - Front service access- The system has full service, front access for routine servicing of components. Front access also narrows the footprint of the system making it possible for units to be placed side by side.
Manageability: - Redundant group control- Allows up to 4 groups of precision air conditioners to communicate with each other for redundancy, demand fighting prevention, mode assist, and global sharing of certain settings.
- Microprocessor controller- Utilizes intelligent, active response control, and real-time monitoring. The system is controlled by a microprocessor providing high level control functionality and human interface via a four line, eighty character, alphanumeric display
- Network interface- Provides management by connecting the device directly to the network with a dedicated IP address, avoiding the need for a proxy such as a server. Management is available via Web browser, Telnet or SSH. Notification features inform you of problems as they occur.
