2. Condensate pump - Wikipedia

   en.wikipedia.org/wiki/Condensate_pump

   A condensate pump is a specific type of pump used to pump the condensate produced in an HVAC (heating or cooling), refrigeration, condensing boiler furnace, or steam system. [ 1 ] Applications

3. Motor capacitor - Wikipedia

   en.wikipedia.org/wiki/Motor_capacitor

   Motor capacitors are used with single-phase electric motors [3]: 11 that are in turn used to drive air conditioners, hot tub/jacuzzi spa pumps, powered gates, large fans or forced-air heat furnaces for example. [1] A "dual run capacitor" is used in some air conditioner compressor units, to boost both the fan and compressor motors. [1] Permanent ...

4. Inverter compressor - Wikipedia

   en.wikipedia.org/wiki/Inverter_compressor

   This type of compressor uses a drive to control the compressor motor speed to modulate cooling capacity. Capacity modulation is a way to match cooling capacity to cooling demand to application requirements. The first inverter air conditioners were released in 1980–1981. [1] [2]

5. Condenser (heat transfer) - Wikipedia

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

   For example, a refrigerator uses a condenser to get rid of heat extracted from the interior of the unit to the outside air. Condensers are used in air conditioning, industrial chemical processes such as distillation, steam power plants, and other heat-exchange systems. The use of cooling water or surrounding air as the coolant is common in many ...

6. Fan coil unit - Wikipedia

   en.wikipedia.org/wiki/Fan_coil_unit

   These motors are sometimes called DC motors, sometimes EC motors and occasionally DC/EC motors. DC stands for direct current and EC stands for electronically commutated.. DC motors allow the speed of the fans within a fan coil unit to be controlled by means of a 0-10 Volt input control signal to the motor/s, the transformers and speed switches associated with AC fan coils are not required.

7. Vapor-compression refrigeration - Wikipedia

   en.wikipedia.org/wiki/Vapor-compression...

   A representative pressure–volume diagram for a refrigeration cycle. Vapour-compression refrigeration or vapor-compression refrigeration system (VCRS), [1] in which the refrigerant undergoes phase changes, is one of the many refrigeration cycles and is the most widely used method for air conditioning of buildings and automobiles.
