Title:
LOW AMBIENT OPERATING PROCEDURE FOR COOLING SYSTEMS WITH HIGH EFFICIENCY CONDENSERS
Document Type and Number:
WIPO Patent Application WO/2011/005470
Kind Code:
A3
Abstract:
A multiple refrigerant circuit cooling system includes at least a first refrigerant circuit (1 11, 1 13, 114, 115) and a second refrigerant circuit (11 Ia, 1 13a, 114a, 115a). Each of said first and second refrigerant circuits (1 11, 113, 114, 1 15, 111a, 113a, 1 14a, 115a) including a compressor (113, 113a), a condenser (114, 114a), an expansion device (115, 115a) and an evaporator (111, 11 Ia) connected in refrigerant flow communication. The condensers (114, 114a) of the first and second refrigerant circuits (111, 113, 114, 115, 11 Ia, 113a, 114a, 115a) each including condenser coils having exterior surfaces (117, 118, 117a, 118a) and each condenser (114, 114a) including at least one fan (123, 124, 123a, 124a) for drawing ambient air across the exterior surfaces (117, 118, 117a, 118a) of its respective condenser coil. The exterior surfaces (117, 118) of the condenser coil of the condenser (114) of the first refrigerant circuit (111, 113, 114, 115) being in fluid communication with the fan (123a, 124a) of the condenser (114a) of the second refrigerant circuit (111a, 113a, 114a, 1 15a) to provide reduced airflow across the exterior surfaces (117, 118) of the condenser coils of the first refrigerant circuit (111, 113, 114, 115) at a low ambient temperature (27).
