Does the car air conditioning not cool when the vehicle is not running?

Car air conditioning can cool even when the vehicle is not running. Below is relevant information about automotive air conditioning: 1. Introduction to Automotive Air Conditioning: Automotive air conditioning consists of a compressor, condenser, throttle element, evaporator, fan, and necessary control components, forming an air conditioning system that regulates the temperature and humidity inside the vehicle to provide a comfortable environment for the driver. 2. Working Principle: When the compressor operates, it draws in low-temperature, low-pressure gaseous refrigerant from the evaporator. After compression, the temperature and pressure of the refrigerant increase, and it is sent to the condenser. Inside the condenser, the high-temperature, high-pressure gaseous refrigerant transfers heat to the outside air passing through the condenser and liquefies, turning into a liquid. The liquid refrigerant flows through the throttle device, where its temperature and pressure decrease, and it enters the evaporator. Inside the evaporator, the low-temperature, low-pressure liquid refrigerant absorbs heat from the air inside the vehicle passing through the evaporator and evaporates, turning into a gas. The gas is then drawn back into the compressor for the next cycle.
