This utility model relates to the field of air conditioner technology, and discloses a heat pump defrosting system and an air conditioner. In the heat pump defrosting system, the high-temperature, high-pressure refrigerant gas discharged from the compressor is directly introduced into the defrosting pipe assembly mounted on the chassis, fully utilizing the inherent high-temperature exhaust waste heat during system operation as a heat source. This design eliminates the traditional electric heating wire method, achieving chassis defrosting with zero additional energy consumption; it eliminates the need for independent electric heating elements and a matching detection and control system, significantly reducing hardware costs and circuit complexity. The high-temperature refrigerant efficiently and evenly melts the ice layer as it flows through the chassis defrosting pipe, ensuring smooth discharge of defrosting water. This not only effectively eliminates poor defrosting, duct blockage, and heating attenuation caused by chassis icing, but also improves overall energy efficiency by directly utilizing the system's circulating energy, significantly enhancing the reliability and economy of the air conditioner under long-term heating conditions.

This application discloses a vehicle refrigeration unit and its refrigeration system, belonging to the related technical field of vehicle refrigeration units. It includes an installation frame with a housing and an inner housing detachably mounted on both sides. An air outlet assembly is located at the top of the inner housing, and the assembly includes a vertically structured mounting plate. External and internal air outlets are respectively located on the two sides of the vertically arranged mounting plate. The beneficial effects of this application are: the refrigerant from the condenser is directly split. During this splitting, one path is throttled and cooled by a throttling device before entering the economizer, while the other path, the un-throttled mainstream refrigerant, enters the economizer. The two refrigerants undergo sufficient heat exchange within the economizer. The throttled, low-temperature refrigerant can more effectively absorb heat from the mainstream refrigerant, thereby significantly increasing the subcooling of the mainstream refrigerant. This results in a lower dryness and higher liquid ratio of the refrigerant entering the evaporator, leading to a higher cooling capacity per unit mass of refrigerant.
