FUJIPURE DC INVERTER TECHNOLOGY SAVES ENERGY BY 40% WITH PROVIDING OPTIMUM COMFORT
High EER/COP Rating
High efficiency is realized by the use of DC Inverter Hermetic Scroll Compressors with high pressure chamber design and improved DC Inverter driving technology, and large heat exchanger.
- ERR, Energy Efficiency Ratio Cooling Capacity (kW) / Cooling Power Input (kW);
- COP, COefficient of Performance Heating Capacity (kW) / Heating Power Input (kW);
- The data refers to a 8HP outdoor unit.
High Efficiency Compressor
- Comparing with normal compressor the DC Inverter Scroll Compressor can save up to 40% of energy consumption in a year.
- Improved DC Inverter motor Low frequency performance is highly raised thanks to the concentrated winding.
- With stepless power regulating technology, the DC Inverter compressor achieves stepless output regulation between 20Hz 120Hz
Precise Temperature Control
The EXV (Electronic Expansion Valve) of each indoor unit respond to the loading changes of indoor environment, continually adjusts the flow rate of the refrigerant.
Meanwhile, the outdoor unit with DC Inverter compressor provides the capacity with certain amount of refrigerant exactly according to the total demands of indoor units.
With the Variable Refrigerant Flow (VRF) technology, teh room temperature can be achieved quickly near to constant value without much temperature fluctuation that occurs with a conventional ON/OFF control system
Quiet operation during night time
Intelligently adjustment of outdoor fan control can reduce the operation noise up to 8dB(A) during night time and it can be lowered to 50dB(A).
Intelligent Defrost Technology
- Defrosting program is designed under the consideration of the operation reliability
- Precise defrosting timing, which is intelligent indeed.
- Its an optimized defrosting program, which will be performed only when system pressure is too low, that can obviously lengthen the time gap between two defrost operations, hence reduce the time of defrosting.
- Heating capacity loss has been decreased by 75% with highly comfortable heating operation.
Wide Operation Range
The unit can operate in wide range, greatly reducing the ambient temperature limitation.
- If the required capacity of indoor units is 50% higher than outdoor unit, cooling range may be up to -15 °8-C.
- If the required capacity of indoor units is 50% lower than outdoor unit, cooling range may be up to -5 °8-C.
Long Piping Design
- Maximum total piping length 500m
- Maximum actual piping length 150m
- Maximum equivalent piping length 175m
- Maximum height difference between indoor units 15m
- Maximum height difference between outdoor and indoor unit 50m*
- Maximum piping length from first indoor branch to the farthest indoor unit 40m
This value is based on the outdoor unit which is located above the indoor unit. If the outdoor unit is located underneath the indoor unit, the value is 40m.
High Static Pressure of Outdoor Fan The maximum external static pressure (ESP) of the outdoor fan can reach up to 75Pa*
The outdoor unit can be installed in the equipments room of high buildings.
* Default ESP of the outdoor fan is 40Pa. If higher ESP is required, re-selection is necessary.
Modular Outdoor Unit Design
- Various combination from 8HP to 64HP with 2HP increments
- Maximum capacity of outdoor unit is 64HP (4x modules)
- Up to 110 sets of indoor units can be connected*
- 12 types and 69 models
- Maximum diversity is 135%
From the standard model that 4 modules connect in parallel, up to 64 indoor units can be connected. If more indoor units are required to be connected, please contact us.
The operating priority sequence of the outdoor unit modules will be changed without restart when the system accumulatively operates for 12 hours which can maximize the service life of the system.
Each module is an independent sub-system, and the whole system wont fail down even if partial malfunction of any one of the modules emergency operation can be performed after simple manual set up on the outdoor PCB switches.
High Efficiency Oil-balanced Technology
- High pressure chamber compressor with oil-balanced pipe can automatically drain out the excess oil which can prevent oil-unbalance between the compressors.
- New patented oil separator allows the oil separating efficiency up to 99%.
- Oil equalizing pipe connection design at the outside of the modules allows high reliability.
- Maximum total piping length 150m
- Maximum actual piping length 70m
- Maximum equivalent piping length 80m
- Maximum height difference between indoor units 10m
- Maximum height difference between outdoor and indoor unit 30m*
- Maximum piping length from first indoor branch and the farthest indoor unit 25m
Long piping design
This value is based on the outdoor unit is located above the indoor unit.
If the outdoor unit is located underneath the indoor unit, the value is 25m.
