GENERAL INFORMATION
Operating Conditions
BAC cooling equipment is designed for the operating conditions specified below, which must not be exceeded
during operation.
•
Wind Load : For safe operation of unshielded equipment exposed to wind speeds above 120 km/h installed at a
height above 30 m from the ground, contact your local BAC-Balticare representative.
• Seismic Risk : For safe operation of equipment installed in moderate and high hazard area's contact your local
BAC-Balticare representative.
ICE THERMAL STORAGE UNIT
1. For units designed to work with direct refrigerants:
- Acceptable Refrigerants: R-717 (ammonia)
- Coil design pressure: max. 22 bar
- Max. temperature of refrigerant in coil(s): +50°C.
- Min. temperature of refrigerant in coil(s): -20°C.
2. For units designed to work with secondary coolants:
- Fluid Compatibility: Fluids circulated through the coil(s) must be compatible with the coil construction
material. Standard coils are constructed of black steel.
- Coil design pressure: max. 10 bar
- Max. temperature of fluid: +50°C
- Min. temperature of fluid: -20°C
PURGE REQUIREMENTS
The installer of BAC equipment must ensure proper system purging of air prior to operation. Entrained air can
obstruct the proper flow of glycol solution, resulting in higher operating pressures than design and reduced thermal
storage capacity.
Connecting Pipework
All piping external to BAC cooling equipment must be supported separately.
All connections in the external pipework (installed by others) must be leak free and tested accordingly. All piping
external to BAC cooling equipment must be supported separately.
Suction pipe sizing should be done according to good practice, which may for larger flows require larger pipe
diameters than the outlet connection. In such cases adapter pieces need to be installed.
