2. Crankcase heater - Wikipedia

   en.wikipedia.org/wiki/Crankcase_heater

   When the compressor temperature rises to or is a specified amount above the lower of the other two temperatures, the crankcase heater is de-energized. [ 5 ] Crankcase heat is common in air conditioning (cooling) systems where R-22 has been used for many years.

3. Coefficient of performance - Wikipedia

   en.wikipedia.org/wiki/Coefficient_of_performance

   The heat pump itself can be improved by increasing the size of the internal heat exchangers, which in turn increases the efficiency (and the cost) relative to the power of the compressor, and also by reducing the system's internal temperature gap over the compressor. Obviously, this latter measure makes some heat pumps unsuitable to produce ...

4. Thermistor - Wikipedia

   en.wikipedia.org/wiki/Thermistor

   The dissipation constant is a measure of the thermal connection of the thermistor to its surroundings. It is generally given for the thermistor in still air and in well-stirred oil. Typical values for a small glass-bead thermistor are 1.5 mW/°C in still air and 6.0 mW/°C in stirred oil.

5. Air compressor - Wikipedia

   en.wikipedia.org/wiki/Air_compressor

   Air compressor supplies air into a nail gun.. An air compressor is a machine that takes ambient air from the surroundings and discharges it at a higher pressure. It is an application of a gas compressor and a pneumatic device that converts mechanical power (from an electric motor, diesel or gasoline engine, etc.) into potential energy stored in compressed air, which has many uses.

6. Compressor characteristic - Wikipedia

   en.wikipedia.org/wiki/Compressor_characteristic

   Compressor characteristic is a mathematical curve that shows the behaviour of a fluid going through a dynamic compressor. It shows changes in fluid pressure , temperature , entropy , flow rate etc.) with the compressor operating at different speeds.

7. Variable-speed air compressor - Wikipedia

   en.wikipedia.org/wiki/Variable-speed_air_compressor

   For example, 10–12% of all power generated in the UK is dedicated to the production of compressed air and a portion of this power is wasted energy. Large electrical cost savings can be achieved by installing a variable speed drive compressor in place of an existing rotary screw or piston machine.

8. Condenser (heat transfer) - Wikipedia

   en.wikipedia.org/wiki/Condenser_(heat_transfer)

   A condenser unit used in central air conditioning systems typically has a heat exchanger section to cool down and condense incoming refrigerant vapor into liquid, a compressor to raise the pressure of the refrigerant and move it along, and a fan for blowing outside air through the heat exchanger section to cool the refrigerant inside. A typical ...

9. Compressed air - Wikipedia

   en.wikipedia.org/wiki/Compressed_air

   Air compressor station in a power plant. In industry, compressed air is so widely used that it is often regarded as the fourth utility, after electricity, natural gas and water. However, compressed air is more expensive than the other three utilities when evaluated on a per unit energy delivered basis. [9]
