Nova poboljšana profesionalna VRV serija klima uređaja sa kapacitetom do 168,0 kW 

Nova KXZ serija ima mogućnost povezivanja tri vanjske jedinice te je moguće dobiti maksimalni kapacitet od 168,0 kW.

Također je predstavljena i Hi-COP KXZXE1 serija vanjskih jedinica VRVa!

Pretkodni model (KX6) – do kapaciteta od 48HP

Nova serija KXZE1 – do kapaciteta od 60HP

Nova serija HI COP - KXZXE1 (Hi-COP) – od 8 do 36HP

Povezivost

Na KXZE1 standardne jedinice je moguće povezati do 200% kapciteta unutarnjih jedinica (za jedinice od 28,0 do 96,0 kW - na zathjev kod narudžbe).

Poboljšana učkinkovitost

Graf ispod prikazuje poboljašanu učinkovitost KXZE1 i Hi-COP serije klima uređaja u odnosu na prethodnu KX6 seriju.

Usporedba EERa u režimu Hlađenja

Usporedba COPa režimu Grijanja

Fleksibilna instalacija

Maksimalna visinska razlika je povećana na 70m.

Maksimalna dužina cijevovoda između vanjske i unutarnje jedinice je 160m.

Peak Cut kontrola

The peak cut function can easily be set on the RC-EX1A control panel. This controls the capacity and provides improved energy savings in the long run. Five-steps of capacity control are available with 100%, 80%, 60%, 40% and 0% settings.

Improved Scroll Compressor

The KXZ has new multiport compressor which includes two additional discharge ports. This optimizes the pressure control within the compressor. The combination of the new multi discharge compressor and the new concentrated winding motor increases the energy efficiency of the compressor in partial load conditions.

This new compressor has proven to be extremely reliable and uses the latest compressor technology.

Priority Operation Mode Rule (KXZ)

The new KXZ has four operation modes:

1. First Unit Operation Mode

- the first unit to operate will set the operation mode

2. Last Unit operation Mode

- the last unit to operate will set the operation mode

3. Majority operation Mode

- the mode selected by the majority of units in operation (whichever greater capacity between the sums of cooling mode and heating mode). The other units in the other mode will go automatically in fan mode.

4. Master Operation Mode

- this is the mode selected by the master unit in operation. The other units in the other mode will go automatically in fan mode.

New Emergency STOP function

Function

The new KXZ has control for emergency stop by external input, i.e. an alarm unit can be connected to the PCB (Printed Circuit Board).

Can be used for leak detection system according to BREEAM.

Improved Heat-exchanger

Strengthened resistance against frost

Outdoor heat exchanger has increased efficiency by improving refrigerant distribution.

The heat exchangers are now 3 rows deep and have more capacity (for 18HP and 20 HP).

Newly designed outdoor unit heat exchanger has a greater surface area and increased volume which equates to greater nominal and seasonal efficiency.

The capillary tubes improve distribution of the refrigerant in the heat exchanger whilst at the same time increasing frost resistance.

Easy Selection Tool – E-Solution

E-Solution is a design software tool which includes specification details of the latest KXZ VRF systems. By using E-Solution this simplifies the process and enables engineers to select the most cost-effective and energy efficient mix of indoor units, outdoor units, pipework and controls. Engineers must register and download the E-solution software to ensure they are automatically sent updates as they become available and this can be done by simply visiting www.mhiae.com/support-downloads/e-solution

Furthermore it is also developed to cater for the design of two and three pipe systems and specifies appropriate models and sizes. It also generates wiring diagrams and engineering drawings which can be exported to AutoCAD or saved in PDF format. This flexibility enables engineers to print select design information and comprehensive operation and maintenance manuals for presentations to clients. Engineers can also incorporate design information into their own formats and documents for personalised proposals.
