Shacman Truck Air Conditioner Has Peculiar Smell And Poor Refrigeration

In hot summer, many car owners driving Shacman truck have felt the high temperature.Especially for vehicles exposed to the sun, the temperature in the car can easily reach 50℃, and entering the car is simply a sauna. As a savior in the hot summer, the car air conditioner has many problems that are disturbed by car owners. It not only has a bad cooling effect, but also has an unpleasant smell. Today I will take you with me to investigate the root causes of bad cooling and strong smell of Shacman truck air conditioner, and help you solve the problem from the source!

Shacman Truck Air Conditioner Has Peculiar Smell And Poor Refrigeration

Working principle of Shacman truck air conditioner.

The air conditioning system of Shacman truck is not only cooling, but also a device to realize the cooling, heating, ventilation and air purification of the air in the car. It consists of compressor, condenser, liquid dryer, expansion valve, evaporator and blower. Copper tubes and high pressure rubber tubes are used to connect components into a closed system. When the refrigeration system works, the refrigerant circulates in this closed system in different states.

Reasons for the bad cooling effect of Shacman truck air conditioner

Insufficient refrigerant

Only if enough refrigerant is present in the air conditioner of Shacman truck, it can be controlled The cold cycle takes heat away to achieve the effect of cooling. If the refrigerant is not enough, the cooling effect of the air conditioner is impaired.

Blocked pipeline

There are many pipelines between condenser and evaporator, and the refrigerant flows in these pipelines. If the pipeline is blocked, the refrigerant can not flow smoothly, can not transfer heat effectively, and the cooling effect becomes worse.

The cold air filter screen is blocked

There is another direct reason why the cooling effect of the air conditioner is poor, because the air filter screen is blocked, resulting in too little air volume at the air outlet.

Poor heat dissipation of the condenser

If the cooler of the condenser is blocked by dirt, the condenser condensing effect will become worse, and the cooling effect of Shacman truck air conditioner will also become worse.

Reasons for the bad smell of Shacman truck air conditioner

Dirty air conditioning filter element

The car air conditioning filter element is a “filter barrier” for the air outside the car to enter the car. If the car air conditioner filter element is dirty and not replaced for a long time, it not only affects the cooling effect of the car, but also pollutes the air in the car and produces peculiar smell, so it needs to be replaced regularly.

The evaporation box of the air conditioner is located in the instrument panel. When the air conditioning is switched on, the cooling and heat exchange of the evaporation boxes is required to produce a large amount of condensed water on its surface. At the same time, the entry of outside air can cause various dust mites, bacteria, impurities, etc. which adhere with condensed water to the surface of the evaporation tank. Over time, these dirty things become moldy with dust and water droplets that condense in the evaporation tank, resulting in a peculiar smell.

Dirty climate channel

The climate duct is the ventilation duct. The climate channel can easily accumulate dust, but is often ignored by humans. If the smell is still not eliminated after cleaning the climate filter element and evaporation box, it is probably the smell caused by the polluted climate channel and the accumulation of bacteria.
