Description

Technical Field

[0001] The utility model belongs to the technical field of direct expansion units, and in particular relates to a direct expansion unit which is convenient for changing the air supply direction. Background Art

[0002] A direct expansion unit, or direct expansion refrigeration unit, is an air conditioning device that uses refrigerant to directly absorb heat in the evaporator to achieve cooling and dehumidification. It compresses low-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure gas through a compressor, and turns it into liquid after cooling through a condenser. It then throttles and reduces pressure through an expansion valve, and finally enters the evaporator to absorb heat from the air to complete the refrigeration cycle. During use, the direct expansion unit will extract wind from its interior and guide cold or hot air to a specific area of ​​use to complete the corresponding cold and hot use. However, most direct expansion units have fixed air outlets and cannot adjust the air supply direction according to actual use needs. This results in the fact that in actual use, due to the layout adjustment of the use area in the later stage and the use needs of different users, it is impossible to maximize the use of the direct expansion unit for the use of cold and hot air, so that its utilization efficiency cannot be maximized, and it may blow directly to the user, resulting in poor comfort. This makes it inconvenient to adjust the air supply direction in later actual use.

[0003] In summary, direct expansion units that are not convenient for changing the air supply direction have some problems in use, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
