Description

Technical Field

[0001] The utility model relates to the field of air conditioning, in particular to an energy-saving system for an outdoor unit of an air conditioner. Background Art

[0002] The outdoor unit of the air conditioner is the core component of the air conditioning system. The forward and reverse fans in the air conditioner need to continuously blow air towards the condenser pipe to help the condenser in the condenser pipe to exchange heat with the air. Its operation requires a lot of electricity.

[0003] In extreme weather, the air conditioner needs to provide a larger heat exchange capacity. The hot or cold air in the condenser pipe cannot easily accumulate in the air conditioner outdoor unit, causing the air conditioner outdoor unit temperature to rise when the air conditioner is cooling (the air conditioner outdoor unit temperature drops when the air conditioner is heating). This will cause the outdoor unit's forward and reverse fan cooling to fail to achieve the expected effect, increasing the outdoor unit's energy consumption. Utility Model Content
