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 heat pump heater has a fan that draws in the outside air and circulates air through an outer evaporator air coil. Liquid refrigerant within the evaporator coil absorbs the heat from the outside air and transforms it into a gas. The warm gas in the coil then passes through the compressor. The compressor increases the heat, creating a very hot gas that then passes through the heat exchanger condenser. As the gas and pool water is pumped through the heat exchanger, the hot gas transfers its heat to the water.
