What are the reasons for the insufficient cooling of the air conditioning in a new Haval H6?

[MacHannah]

Reasons for the insufficient cooling of the air conditioning in a new Haval H6 include: excessive refrigerant, insufficient refrigerant, and excessive impurities. The following are detailed explanations: 1. Excessive refrigerant: If there is too much refrigerant, it will affect its heat dissipation. If too much cooling oil is added during maintenance, the heat dissipation of the refrigeration system will decrease. 2. Insufficient refrigerant: If there is insufficient refrigerant in the air conditioning system, the amount of refrigerant sprayed into the evaporator from the expansion valve will also decrease, leading to a reduction in absorbed heat and a decrease in cooling capacity. 3. Excessive impurities: If there are too many impurities in the refrigerant and refrigeration oil throughout the air conditioning system, the filter screen of the filter may become clogged, reducing the passage capacity of the refrigerant and increasing resistance. Consequently, the amount of refrigerant flowing to the expansion valve will decrease, resulting in insufficient cooling capacity.
