1. High Efficiency & Comfort
Improved Efficiency
The below graphs highlight the improved efficiencies between the previous models compared to the KXZ standard and Hi-COP models.
Multiport compressor that achieves high efficiency
The new multiport discharge area in the compressor has optimized pressure control with better balancing.
The performance improvement at medium Hz has resulted in higher annual efficiencies.
Concentrated winding motor achieves "High Output" and "Total Efficiency Improvement"
The newly designed high performance CP enables high precision optimization for compressor speed, which leads to concentrated winding motor use.
Our product achieves high output and better energy saving effects and in particular improves seasonal efficiency rating.
Improved Heat-exchanger
With piping layout rearranged from header to heat exchanger, refrigerant distribution flow has improved and maximum energy efficiency has been achieved. Heat exchanger has improved refrigerant distribution and increased effectiveness.Furthermore due to expansion of effective heat transfer area in heat exchanger, energy efficiency has increased.
Strengthened resistance against frost
Resistance against frost has been strengthened by achieving improved heat-exchanger.
Vector control
New applied Vector control has a high efficiency and many new advanced features.
- Smooth operation from low speed to high speed.
- Smooth Sine Voltage Wave form are attained.
- Energy efficiency is further improved in low speed range.
Long-chorded 3 propeller fan with serration
Fan blade design adapted from Mitsubishi Heavy Industries aerospace division - with serrated edges that deliver increased air volume with less power input.
DC Fan Motor
Employment of DC fan motor has enabled to realize an excellent efficiency of approximate 60% higher than previous models.
2. Design Flexibility
Indoor unit capacity connection
120% capacity connection.
Connectable indoor units
Connect up to 8 indoor units.
Phạm vi hoạt động rộng
KXZ series permits an extensible system design considering a heating range operation under a low temperature condition down to -20˚C and a cooling range operation up to 46˚C (previous model : 43˚C)
Furthermore Mitsubishi Heavy VRV Heat pump systems KXZ Lite inverter (8.0Hp) FDC224KXZPE1 extends a cooling range operation up to 50˚C.
Easy Transportation & Installation
Due to realization of significant reduction in size and foot print which is one ofthe smallest in the industry.
Automatic Select functions for capacity control
The following 3 items are available for capacity control function. User can select one item individually or select 2or3 items at the same time. In case of selecting 2 or 3 items, the unit will operate with the most effective function automatically.
Compressor speed control
- User can set compressor speed at 100%-80%-60%-40% before starting operation with PWB in the outdoor unit or with a demand controller (procured locally).
Capacity control timer
- User can set capacity control with RC-EX3 up to 4 times per day maximum. The timer setting can be changed using 5 minute intervals.
Silent mode
- Considering noise regulations or surrounding circumstances, you can now select 4 levels of silent mode. Setting the combination of silent mode is available by using timer function of RC-EX3.
Priority operation mode rule
User can select the following priority operation mode. (for whole system)
1. First unit’s operation mode (by default setting).
2. Last unit’s operation mode.
3. Majority operation mode (see below).
4. Master operation mode (see below).
Majority operation mode: The system is operated according to the mode selected by the majority of units in operation (whichever greater capacity between the sums of cooling mode and heating mode). The operation mode in minority is set to fan mode automatically.
Master operation mode: The system is operated according to master operation mode. When master operation mode is set at cooling mode, units selected as heating mode is set to fan mode automatically.
Improved features
- Improved freedom of piping layout.
- Wire insertion holes for fall prevention.
- External static pressure.
- Four handles.
- A transparent rain cover.
- Fixing screws to service panel.
