An air-conditioner complex consisting of an indoor unit 4FGN500HY1, and four outdoor units RCN125HY19
Features of the indoor unit
- Indoor Air Quality: A 2-inch rail is provided at return air for installation of field-supplied filter.
- Tough Casing: Casing made of electro galvanized mild steel, coated with epoxy polyester for protection against corrosion.
- Changeable Drive Package: The belt driven evaporator motor allows the change of pulley on-site to accommodate different static pressure and air flow requirements.
- Polyethylene (PE) Insulation: 10mm-thick, fire-resistant insulation with durable surface that resists tough dirt and has a higher degree of puncture resistant comparedto fiberglass.
- Part Load Operation: The modular unit configuration allows it to operate under part load conditions to meet the required cooling capacity.
- Heat Exchanger: Seamless inner grooved copper tubes for optimum heat transfer.
- Design: Flexible, easy to install and maintain, suitable for factories, large spaces such as wedding parties, office blocks, food warehouses...
Features of the outdoor unit
- Condenser Fan Motor with IP55 Ingress Protection: The motor is designed with dust proof bearing to ensure the reliability and smooth operation.
- Service-friendly Design: Easy access to compressor and control panel. Fan motor assembly can easily be removed for servicing. Condenser coil is easier to clean as it has lower resistance to air flow, thus accumulates lesser dust.
- Service Access Valve: Valves are provided for installation of pressure gauge at site. These valves are easily accessible without the needs to open the service panel.
- Long Piping: Maximum piping length and elevation of 75m and 30m respectively, providing design flexibility for large-sized buildings.
- High efficiency scroll compressor: High efficiency, low noise and hermetically sealed scroll compressor for optimum performance. It also comes with an internal overload protection and crankcase heater.
Auto Random Restart with Last-State-Memory
In the event of a sudden power failure during operation, Daikin Duct type Packaged Air Conditioner 4FGN500HY1 restarts automatically in 64 different recovery timing patterns (within 180 seconds to 244 seconds) and the unit will operate based on the previous setting (operating mode, temperature setting and fan speed). This ensures that air conditioners in the same building resume randomly instead of all units resuming at the same time, preventing power surge after a blackout.
Microchannel at a Glance
The condenser’s heat exchanger is made up of all-aluminium microchannel coil. Comparing to the conventional fin-and-tube coil, the microchannel coil resists galvanic corrosion and has a stronger structure. With the same face area, the microchannel coil requires lesser refrigerant charge while providing better heat exchange, and is lighter over the conventional fin-and-tube coil.
