Jenis dan instalasi unit kumparan kipas

Daftar Isi

In the technical framework of modern building HVAC (Heating, Ventilation, and Air Conditioning) systems, Fan Coil Units (Fcus) serve as critically important terminal devices. This article will delve into aspects such as their classification, configuration, and maintenance to further enhance the understanding of fan coil units.

Fan coil unit type from CDAIRTECH

Installation method

  • Horizontal concealed installation: Hidden in the ceiling (ceiling interlayer), suitable for hotel guest rooms and offices.
  • Vertical exposed installation: Floor-standing design for easy maintenance, applicable to small commercial shops.
  • Cassette : Four-way air outlet for uniform air distribution, commonly used in conference rooms.
  • Ultra-thin type: Height ≤250mm, suitable for low-clearance spaces (MISALNYA., loft apartments).

Functional Characteristics

  • Dual-source type: Connected to both cold and hot water systems simultaneously to achieve year-round temperature control, keeping indoor temperature within a small fluctuation range throughout the year.
  • With fresh air function: Integrated with a fresh air module and equipped with high-efficiency filters, it realizes indoor fresh air exchange while preventing indoor air pollution, thus improving indoor air quality.
  • Quiet type: Suitable for places with high noise requirements (usually noise level ≤30dB (A)), such as hospitals and libraries.

FCU Installation

Pre-installation Preparation

Calculation and Selection:Calculate the required cooling or heating load using the sensible heat formula:Q=c×M×ΔT(wherec = specific heat of airM = air volume)

Space Planning:Concealed FCU Installation: Reserve a maintenance access panel near the unit.
Ensure the ceiling cavity space is ≥500mm to facilitate fault diagnosis and maintenance. Exposed FCU Installation:Avoid placing flammable or moisture-prone items within ≥1.0m around the FCU to prevent potential losses during malfunctions.

Key Materials: Copper pipes or hoses: For connecting to supply and return water pipes. Insulation cotton: Fully wrap exposed pipes to minimize heat/cold loss. Condensate pipe: Connected to drain condensed water from air (slope ≥1%)

Installation Process

Step-by-step breakdown:
Lifting bracket fixing → connecting water pipe (welding or ferrule) → electrical wiring → condensate test

Caution:
The front end of the water supply pipe should be equipped with a valve to stop the use or maintenance.
Avoid clogging of the coil (Y-filter installation is recommended).
Condensate pipe should be designed to prevent backslope

Debugging and Acceptance

  • Volume Udara:
    Detected by an anemometer to ensure the motor operates normally.
  • Water Flow Rate:
    Measured by an ultrasonic flowmeter to verify no deviation from the design value.
  • Temperature Control Accuracy:
    Tested with a supporting room thermostat to ensure the deviation between the detected temperature and the set temperature does not exceed the standard range (recommended deviation: ±0.5°C).
