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.
Description of a basic chiller refrigeration system: Starting at the compressor; the refrigerant is compressed and sent out of the compressor as a high temperature, high pressure, superheated gas. The refrigerant travels to the condenser (Which can be air cooled by fans or water cooled by tower or city water). The condenser changes the refrigerant from a high temperature gas to a warm temperature liquid. It then travels into a receiver (optional component). It continues to the Thermal Expansion valve or TXV.
