Does using air conditioning in summer or winter consume more fuel?

[NolanRose]

Using air conditioning in summer consumes more fuel than in winter. Reasons why air conditioning consumes more fuel in summer than in winter: In summer, the car's air conditioning cools the interior, while in winter, it heats the interior. Generally, when the car's air conditioning is used in winter, the engine generates heat as soon as the car starts, and part of this heat is transferred from the engine to provide warmth, saving a significant amount of fuel. How car air conditioning works: Based on signals from various sensors that detect the interior temperature, evaporator temperature, engine coolant temperature, and other relevant switch signals, the system outputs control signals to manage the operation of the radiator fan, condenser fan, compressor clutch, blower motor, and air control motor, achieving automatic control of the interior temperature.
