A normal or desirable cholesterol level is defined as less than 200 mg of cholesterol per deciliter of blood (mg/dL). Blood cholesterol is considered to be borderline when it is in the range of 200 to 239 mg/dL. Elevated cholesterol level is 240 mg/dL or above.
Compressor Crankcase Heater. During the normal operation of a central air conditioner or heat pump the compressor is both drawing suction from the evaporator and discharging hot gas into the condenser coil. While running, there is enough heat being generated by the compressor running to keep from creating refrigerant migration from occurring.
Vapor Compressor Chiller. A vapor-compression chiller consists of four primary components of the vapor-compression refrigeration cycle. They include a compressor, evaporator, condenser and a metering device. Vapor-compression chillers typically utilize HCFC or CFC refrigerants to achieve a refrigeration effect. Compressors are the driving force in a vapor-compression chiller and act as a pump for the refrigerant.
