A heating and cooling system known as an air source heat pump pulls heat from the outside air and transfers it inside a building for space heating or cooling. It functions as an energy-efficient substitute for conventional heating, ventilation, and air conditioning (HVAC) systems by compressing refrigerant gas to absorb and release heat. Owing to their adaptability and suitability for use in commercial, industrial, and residential settings, air source heat pumps help save energy and have a smaller negative environmental impact.

Aircraft engine electrical wiring harnesses and cable assembly refer to the routing of the cables and wires in an aircraft engine to transmit signals or power.
