   The mechanical component of MEP is an important superset of HVAC services. Thus, it incorporates the control of environmental factors (psychrometrics), either for human comfort or for the operation of machines. Heating, cooling, ventilation and exhaustion are all key areas to consider in the mechanical planning of a building. [4]

6. 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]

7. Mechanical systems drawing - Wikipedia

   en.wikipedia.org/wiki/Mechanical_systems_drawing

   Mechanical systems drawing is a type of technical drawing that shows information about heating, ventilating, air conditioning and transportation (elevators and escalators) around a building. [1] It is a tool that helps analyze complex systems.
