Does running a hot air conditioner in a car consume fuel?

When you turn on the air conditioner, if you use the engine's circulating water to raise the temperature inside the car, you won't consume extra fuel, but if you still use the compressor to produce warmth, you will consume more fuel! Turn off the compressor and you won't burn any gas.

There is an "A/C" button on the air-conditioning panel, which is also used for heating, and if you use that function, it will consume fuel because the compressor will heat up the air-conditioning unit if you press that button. If you don't press it, you can turn the air conditioner to the highest setting, and part of the engine heat will flow out through the air conditioner to produce heat, so it doesn't consume fuel.

Ground source heat pump air conditioning is the use of energy-saving and environmentally friendly ground source heat pump system, its cooling and heating source using the installation of flexible, easy to control buried pipe soil source heat pump system, also known as soil-coupled heat pump system. Specifically, it adopts the buried pipe method of vertical burial, using water as the carrier of cold and heat, and the water circulates between the heat exchange pipe buried in the soil and the heat pump unit, realizing the heat exchange between the unit and the earth soil.

In winter, the circulating water absorbs heat from the soil through the high density polyethylene pipe loop buried in the soil, so that the temperature of the circulating water rises and is supplied to the ground source heat pump unit, and at the same time, hot water is supplied by the heat pump unit for indoor heating through the radiant floor; in summer, the circulating water discharges the heat to the soil through the buried pipe, so that the temperature of the circulating water is lowered and is supplied to the ground source heat pump unit. Then the heat pump unit provides chilled water, through the fan coil to the indoor cooling.
