Why does the car air conditioning not cool in high temperatures?
1 Answers
Car air conditioning not cooling in high temperatures is due to a lack of refrigerant. The following is a related introduction to car air conditioning: 1. Air conditioning layout: Different types of air conditioning systems have different layout methods. Currently, cars widely use integrated heating and cooling air conditioning systems. The layout form involves assembling the evaporator, heater radiator, centrifugal fan, and control mechanism together, known as the air conditioning unit assembly. 2. Air conditioning components: Modern air conditioning systems consist of refrigeration systems, heating systems, ventilation and air purification devices, and control systems. Car air conditioning generally includes the compressor, electronically controlled clutch, condenser, evaporator, expansion valve, receiver-drier, pipelines, condenser fan, vacuum solenoid valve, idle speed controller, and control system. Car air conditioning is divided into high-pressure and low-pressure pipelines. The high-pressure side includes the compressor output side, high-pressure pipelines, condenser, receiver-drier, and liquid pipelines; the low-pressure side includes the evaporator, accumulator, return pipelines, compressor input side, and compressor oil pan.
