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.
Installation for this type of system typically consists of two parts: an indoor unit called an air handler and an outdoor unit similar to a central air conditioner, but referred to as a heat pump. A compressor circulates refrigerant that absorbs and releases heat as it travels between the indoor and outdoor units.
