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.
The warm refrigerant gas is then sent back to the compressor to start the cycle over again and the newly chilled water in the separate loop can now be used for cooling. To the top of the page Absorption Chiller An absorption chiller uses a heat source to drive the refrigeration cycle in place of a mechanical compressor.
