2. Inverter compressor - Wikipedia

   en.wikipedia.org/wiki/Inverter_compressor

   In air conditioning, an inverter compressor is a compressor that is operated with an inverter. In the hermetic type, it can either be a scroll or reciprocating compressor . This type of compressor uses a drive to control the compressor motor speed to modulate cooling capacity.

4. Mixed-mode ventilation - Wikipedia

   en.wikipedia.org/wiki/Mixed-mode_ventilation

   Mixed-mode ventilation is a hybrid approach to space conditioning that uses a combination of natural ventilation from operable windows (either manually or automatically controlled), and mechanical systems that include air distribution equipment and refrigeration equipment for cooling. A well-designed mixed-mode building begins with intelligent ...

   Central, "all-air" air-conditioning systems (or package systems) with a combined outdoor condenser/evaporator unit are often installed in North American residences, offices, and public buildings, but are difficult to retrofit (install in a building that was not designed to receive it) because of the bulky air ducts required. [32] (Minisplit ...

7. Heat pump and refrigeration cycle - Wikipedia

   en.wikipedia.org/wiki/Heat_pump_and...

   Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. [1] A heat pump is a mechanical system that transmits heat from one location (the "source") at a certain temperature to another location (the "sink" or "heat sink") at a higher temperature. [2]
