Question

Technician A says that an air-conditioning system removes heat from inside the engine. Technician B says that the heating system removes heat from the inside of the vehicle. Who is correct?

1) Technician A
2) Technician B
3) Both Technicians
4) Neither Technician

Answer 1

Both Technician A and Technician B are incorrect; air-conditioning systems remove heat from the interior of a vehicle or building, and heating systems transfer heat from the engine to the interior of a vehicle.

Step-by-step explanation:

Neither Technician A nor Technician B are correct in their statements. The role of an air-conditioning system is not to remove heat from inside the engine; instead, its function is to remove heat from the interior of a vehicle or a building to cool it down. In contrast, the vehicle's heating system does not remove heat from the interior; it transfers heat from the engine to the interior to warm it up.

An air conditioner operates by transferring heat from a cooler environment (such as the inside of a room) to the warmer outside environment. This process requires work input and results in removing heat from the interior space, which is then expelled outdoors.

The vehicle's heating system typically takes advantage of the heat generated by the engine and, via a heat exchanger, transfers that heat to the cabin of the vehicle. Hence, the heating system adds heat to the interior, rather than removing it.
