The vertical exposed fan coil unit is an end device of central air-conditioning systems, mainly used for temperature regulation in public places such as hotels, hospitals, and office buildings. It features efficient heat exchange, low-noise operation, and an exposed design, making it suitable for environments that require independent temperature control and have high aesthetic requirements. [1] The vertical exposed fan coil unit consists of a centrifugal fan, a copper tube heat exchanger, a galvanized steel sheet shell, and a condensate pan. It adopts a double-inlet centrifugal fan wheel and a permanent magnet motor to achieve low-noise operation (≤54dB(A)).
- Efficient Heat Exchange: Combines copper tubes with aluminum fins, and ensures tight contact through the hydraulic tube expansion process to enhance heat exchange efficiency.
- Low-Noise Design: Equipped with a wide-angle volute and a multi-blade centrifugal fan wheel, it covers an air volume range of 340-2380 m³/h. Meanwhile, the permanent magnet motor reduces operating noise.
- Safety and Reliability: The brass water collector/distributor optimizes water flow distribution; the extended condensate pan, combined with a 5° drainage slope, prevents leakage. Additionally, it passes a 2.8MPa high-pressure leak test.
- Easy Installation: No ceiling is required—it can be directly placed on the floor or under the windowsill of exterior walls. The shell adopts an electrostatic spraying process and complies with the national standard GB/T 19232-2003.
It is suitable for places with high requirements for air cleanliness and noise control, such as hotel guest rooms, hospital wards, and shopping malls. It supports three-speed air volume adjustment and linkage control with a thermostat. Some models can be optionally equipped with a TiO₂ sterilizer to improve air quality.
- Terminology Accuracy: Professional terms in the HVAC field are accurately translated, e.g., "立式明装风机盘管" as "vertical exposed fan coil unit" (specifying both "vertical" installation form and "exposed" mounting type), "紫铜管换热器" as "copper tube heat exchanger" (common industry expression for copper tube-based heat exchange components), and "永磁电机" as "permanent magnet motor" (standard term for motors using permanent magnets).
- Data & Standard Presentation: Key data like noise level (≤54dB(A)), air volume range (340-2380 m³/h), pressure for leak test (2.8MPa), and national standard number (GB/T 19232-2003) are retained in their original form to ensure precision, which is crucial for technical documentation.
- Logical Structure: The original Chinese structure (product overview → composition → core features → application scenarios) is preserved. Core features and application scenarios are presented in lists/subheadings for clarity, aligning with the reading habits of English technical texts.
- Cultural & Contextual Adaptation: "对美观要求较高" is translated as "have high aesthetic requirements" (instead of literal "beautiful appearance requirements") to fit the context of evaluating industrial product design; "三档风速调节" as "three-speed air volume adjustment" accurately conveys the functional meaning of adjustable fan speeds.
