A protective device for protection of a refrigeration compressor from burnout caused by short cycling. A time delay means is provided which prevents the compressor motor from being started again until a predetermined time interval has elapsed after the system thermostat has opened. If a power ...
1. A defrosting arrangement for a closed cycle refrigeration system employing a centrally located refrigerant compressor and condenser and remotely located evaporator means, comprising, means for providing only a portion of the total hot compressed gaseous refrigerant output from the compressor at substanti...
点击查看答案 第4题 If the suction pressure for an operating refrigeration compressor is below normal, the cause may be ___. A.an excess of liquid refrigerant B.the expansion valve overfeeding C.a fouled compressor suction strainer D.the compressor short cycling 点击查看答案 热门考试...
Short CyclingCompressor - this can be caused by a low charge or faultymetering device. Airflow across the evaporator coil can also result in this issue and can be from adirty or clogged air filterorfrozen evaporator coil. Abad capacitorcan also cause the problem. ...
In accordance with the present invention, the compressor is selectively unloaded when it is providing too much refrigeration, while permitting it to continue running without the risk of overheating, short cycling, oil pump-out, and while providing significant power savings over other systems, such as...
Each fan section is baffled to prevent short cycling of the air. The unit is designed to be mounted flush to the ceiling and meets all NSF requirements. The top pan is slotted for simple installation. Drain fittings are installed in the bottom of the drain pan for easy field connection, ...
C.liquid refrigerant returning to the compressor D.the compressor short cycling on the high pressure cutout 点击查看答案 第4题 If a refrigeration system compressor crankcase is sweating, you should ___. A.add refrigerant to the system B.adjust the thermal expansion valve to the proper setting...
A close sorption system is almost like a conventional vapor compression cycle, and a sorber bed replaces only the mechanical compressor, which provides the necessary thermal compression to the refrigerant. In the charging/desorption process, hot fluid exchanges heat with the sorber bed, which ...
