Why is the parking air conditioning not cooling effectively?

[DelElliott]

It may be due to insufficient refrigerant or a dirty condenser. Below is relevant information about vehicle air conditioning systems: 1. Introduction to vehicle air conditioning: The vehicle air conditioning system consists of a compressor, condenser, throttle element, evaporator, fan, and necessary control components, designed to regulate interior temperature and humidity, providing a comfortable environment for drivers. 2. Working principle: When the compressor operates, it draws in low-temperature, low-pressure gaseous refrigerant from the evaporator. After compression, the refrigerant's temperature and pressure increase, and it is sent to the condenser. Within the condenser, the high-temperature, high-pressure gaseous refrigerant transfers heat to the outside air passing through the condenser, causing it to liquefy into liquid form. When the liquid refrigerant flows through the throttle device, its temperature and pressure decrease before entering the evaporator. In the evaporator, the low-temperature, low-pressure liquid refrigerant absorbs heat from the interior air passing through the evaporator and evaporates into gas. This gas is then drawn into the compressor to begin the next cycle.
