Characteristics of air conditioning unit

1. Outline frame structure: The unit adopts an aluminum alloy frame structure, which is made of high-strength aluminum alloy special profiles. Each corner of the frame is made of special structural castings, and the profiles and corners are connected by an insertion structure. This structure has the following characteristics:

A. Good mechanical strength, light weight, corrosion resistance, beautiful appearance, and accurate dimensions.

B. The structure assembly is flexible, easy to disassemble and inspect on site, and has a longer service life than steel structure frames.

2. Box panel structure:

A. The unit box panel adopts an inner layer of galvanized steel plate and an outer layer of colored steel plate structure. The high-density polyurethane foam insulation material is filled between the two layers of steel plates, which has better insulation performance than other insulation materials such as glass wool. There is no cold bridge generated in the casing during operation under various climatic conditions and working conditions.

B. The panel is fixed by a special method and sealed with sealing materials to enhance air tightness and insulation. This panel structure has advantages in insulation, noise reduction, and strength. All have the best performance and are suitable for places with high air quality requirements.

3. Fan and motor:

A. The fan used by the unit is a double inlet centrifugal fan, which has undergone strict dynamic and static balance tests and runs smoothly.

B. The fan bearings adopt sealed rolling ball bearings, which are pre filled with lubricating oil and have functions such as automatic centering, automatic self-locking, and thrust prevention. Normal use is maintenance free.

C. The fan of the small-scale unit is directly driven by an external rotor motor, without the need for belt transmission, making maintenance and upkeep convenient.

4. Filter: The unit adopts a plate type initial efficiency filter. The filter material adopts a cotton convex mesh, which can be cleaned multiple times.

5. Surface cooler: The selected parameters of the surface cooler are designed using professional selection software. The standard surface cooler is a copper tube with a diameter of 12.7, which is tightened using a copper tube series corrugated aluminum fin method and an integral expansion tube. The copper pipes are arranged in a staggered manner, which gives them high heat transfer performance, low airflow resistance, and superior corrosion resistance, thereby ensuring that the surface cooler has a high heat transfer coefficient and a longer service life.

5. Applicable places for air conditioning units:

Air conditioning units come in three series: vertical, horizontal, and ceiling mounted, designed to meet various functions such as cooling, heating, humidification, dehumidification, and purification. They are widely used in comfortable settings such as hotels, theaters, shopping malls, and office buildings, and can also meet the needs of industries such as electronics, chemical, medical, pharmaceutical, cigarette rolling, food, and light industry.
