Cooling Systems Sample Clauses
Cooling Systems. The cooling systems shall be of sufficient size to maintain all engine and transmission fluids and engine intake air at safe, continuous operating temperatures during the most severe operations possible and in accordance with engine and transmission manufacturers’ cooling system requirements. The cooling system fans, minimum 4, and control shall sense the temperatures of the operating fluids and the intake air and if either is above safe operating conditions the cooling fan should be engaged. The fan control system shall be designed with a fail-safe mode of “fan on.” The cooling system in new condition shall have an ambient capacity of at least 115° F with water as coolant and sea level operation. All cooling system heating devices and procedures shall be of the type recommended by the engine manufacturer and approved by Pace. The highest watt rated 110 VAC block heater as allowed by the engine manufacturer shall be provided and the power cords routed safely with a corrosion proof covered plug receptacle. The power cord receptacle cover shall be purchased a color closely matching the final exterior color. The power cord shall automatically eject itself when the Trolley run control is turned to the power on position.
Cooling Systems. Cooling technology is a key element in PEM fuel cells stack, especially for the automotive sector, where high power density and lightweight are mandatory. Cooling for CHP application is less critical than in automotive. Different methods and media are used to remove heat from the stack: airflow cooling, heat spreaders (edge cooling), liquid cooling and phase-change cooling10. Air-cooling is suitable for small, low power density systems. Cooling channels can be made in bipolar plates or in dedicated cooling plates between the bipolar plates. Demonstration of air cooled stacks with optimized air flow channels shows parasitic energy consumption around 2-3% of the stack power. One of the major drawbacks of air cooling is non uniform temperature distribution between the cells. Edge cooling (or passive cooling) relies on heat conduction in the in-plane direction of plates to remove heat from the central region of the stack, then rejected to heat-spreaders. To be effective, it requires high
Cooling Systems. Radiator fan motor and blades, fan clutch, heater control valve and coolant recovery unit.
Cooling Systems. Engine cooling water radiator, heater radiator, thermostat & housing, viscous cooling fan couplings and water pump.
Cooling Systems. The cooling systems are composed of a refrigeration generator, a primary circuit, re-cooling and a secondary circuit as cooling water circuit with design according to technical and economic criteria in the course of planning to 6/12°C or 10/16°C and circulating air cooling units as well as process refrigeration connections according to performance report. The plants must be equipped to use free cooling in the cold season (heat exchangers, circulating pumps, control valves, etc.). The essential operating parameters of the plants are monitored by MSR technology with operating and fault messages. Chillers are planned as chillers with compression chillers to provide the cooling energy according to the performance report. Circulating air cooling for all rooms with heat loads according to the technical data room? via cooling water supply (with condensation water insulation), including electrical connection. Ceiling circulating air cooling units, in areas with false ceiling as cassette units in the grid dimension of the false ceiling, in laboratory areas and areas without false ceiling via suspended false ceiling circulating air cooling units. Circulating air cooling units consisting of air/refrigerant medium heat exchanger, fan, condensation collecting tray with condensation pump and ventilation outlet. Control via valve with thermoelectric actuator and multi-stage fan. The condensation produced is collected via a central pipe system and is disposed of via a waste water connection. Control by self-sufficient room operating units for room by room control of the circulating air units and heating surfaces with automatic interlocking of heating and cooling against each other. Positions and discharge direction of the circulating air cooling units according to the coordination to be carried out. Design according to power performance.
