Description

Technical Field

[0001] The utility model relates to the technical field of parking air conditioners, in particular to a roof-mounted parking air conditioner with a small number of interfaces. Background Art

[0002] The roof-mounted parking air conditioner designs the compressor, condenser, throttling element, evaporator, fan and other components of the air conditioner into a single body, which is installed at the roof skylight position and powered by the vehicle's onboard battery to adjust and control the temperature inside the vehicle and provide a comfortable environment for the passengers.

[0003] The currently designed parking air conditioner, such as the attached Figure 5 As shown, in the prior art, there are 6 interfaces on the connecting pipelines between the compressor, condenser and evaporator, 2 of which are welding interfaces and 4 are O-ring sealed + threaded interfaces, wherein there is an exhaust pipe assembly between the compressor and the condenser, an intake pipe assembly between the evaporator and the compressor, and a filter tube assembly between the condenser and the evaporator, wherein the exhaust pipe assembly and the intake pipe assembly are both hoses with an aluminum sleeve riveted to a copper tube and an aluminum tube at both ends, and the filter tube assembly is a copper tube welded at each end of the filter tube.

[0004] There are a lot of interfaces, many leakage points, and a high failure rate. In addition, there are a lot of parts and interfaces between parts. In particular, the dimensions of the two pipe joints in the interface design of O-ring sealing + threaded compression need to be strictly controlled. If the gap between the two is too large, the O-ring compression will be too small, resulting in leakage; if the gap between the two is too small, the O-ring compression will be too large, resulting in installation difficulties. The O-ring is easily damaged during installation, resulting in leakage. This design has a large number of parts, a large number of interfaces between parts, a high production cost, a long production cycle, and a high failure rate. To this end, we proposed a roof-mounted parking air conditioner with a small number of interfaces to solve this problem. Utility Model Content
