Technology
Aluminium heat exchanger with hydrophilic coating
Improved wettability of the heat exchanger aluminum plates which have a special coating with a hydrophilic layer, ensuring rapid removal of condensate from the indoor unit that does not allow to quickly form of mold and bacteria, providing a more efficient operation of the air conditioner.
Compresor DC inverter
Compressor with inverter DC can increase the efficiency of the air conditioner, thus reducing power consumption saves your costs. This system is much more economical and safer than air conditioners with a constant output of the compressor.
Low Ambient Cooling
Low-temperature (season) set - used for the operation of the air conditioner in cooling mode at low ambient temperatures (usually provided in the air conditioner as an optional feature). The kit includes: the controller of the outdoor unit fan motor, compressor crankcase heater and heater drain line.
In some series of inverter split systems this option is implemented in hardware and software, thus if there is a need to use the air conditioner in the winter for cooling, you must install only drain the heater.
Multi-Bend Heat Exchanger
Increased heat. This unit uses the heat exchangers with tubes of a special design, the inner surface of which has trapezoidal notches "Innergrove cooper", which provides maximum heat transfer surface area increased. Due to this heat increases by 28%, reduced power consumption, and hence increases the efficiency of the system.
Sine-Wave Inverter
Technology 180° -gradusnogo wave inverter conversion - control voltage without the "pulse" effects (jagged sinusoid).
Compared with the current standard of 120° rectangular wave has the following advantages:
- Ability to work with a wider range of supply voltage and frequency.
- Most of the energy efficiency and energy conservation.
- More soft start, lower noise and vibration.
- more control.
Description
V4+K series achieved world’s largest capacity of 72HP by combining maximum 4 outdoor units with 6 different capacities. (8, 10, 12, 14, 16 and 18HP), and 64 indoor units can be connected max.
V4+ K Series realized the industry's top class energy efficiency with cooling and heating COP by adoption of Brushless Reluctance DC compressor control, DC Fan motor and improved heat exchanger performance with a new design.
Lineup of heat pump types is 8 to 72 HP. Indoor units consist of 14 types with a total of 102 models (not including Outdoor Air Processing Units), capacity ranges from 1.8kW to 28kW. A maximum 130% indoor unit’s connective ratio is allowed for all outdoor unit capacities. This wide selection of models makes it possible to build a system that suits the customer’s requirements.
V4+ K Series intelligent control, according to the system load, cyclically changes start-up sequence of multiple outdoor units, equalizes compressor duty and extends operation life-span. Take 48HP system for example.
In the event of an outdoor unit fail, the field set back-up function in the outdoor unit in question (also between different outdoor units) will allow emergency operation of another outdoor unit, in order to maintain the interim capacity.
Dynamic vector balance tech., no need to install gas balance pipe:
• High-precision pressure sensor monitors the system pressure on time and transfers the data to master unit
• Master unit sends the pressure date to every unit and make sure each outdoor unit in balance situation.
Oil balance pipes set among the modules, and individual oil balance vector control ensures oil distribution among the modules to compressor smooth and reliable running. When one compressor’s oil is overfull, oil balance pipes and outlet pipes both send the oil to system, and then system in average distributes the oil to the other compressors.
Adopts high efficient centrifugal-type oil separator, which separate the oil from discharged refrigerant with up to 99% effect to make all the lubricant discharged from compressor can be returned in time.
- New designed low pressure liquid receiver with high efficiency of oil-return effect.
- Oil balance ensures sufficient refrigerant lubricant supply. Elaborately designed oil-return hole, which ensure reliable oil-return for every compressor.
Centrifugal oil separator can be up to over 99% separating efficiency, which in time and efficiently send the oil to compressors to ensure compressor oil volume. System auto back oil design can complete through PC core send oil back instruction by system running time and state.
The accumulator is large volume design, which can more save refrigerant to avoid liquid strike.
Multi back oil holes can ensure compressor smooth back oil.
Compressor soft start complete low frequency and low current start by DC Inv. compressor, and to reduce strike to electric network. When start DC Inv. Compressor, system runs in large volume and offer more heating capacity. And use the start rapidly advantage of fixed frequency compressor to quickly up to output aim.
- Compressor soft start.
- Lubrication system soft start.
Addressing outdoor units and indoor units are automatically done just by pressing the button of the controller.
- The outdoor unit can automatically distribute the address to indoor units without any manual settings. • Wireless controller can enquiry and modify every indoor units address.
- Up to 64 indoor units can be connected to one system and identified automatically.
It is possible to enable the shared use of the wiring between indoor & outdoor units, as well the centralized control. Hence make it easy for the user to retrofit the existing system with a centralized control, by simply connecting it to the outdoor units.
- PQE & XYE, just only one group of communication wire of PQE, achieved both of communication for indoor & outdoor unit and network.
- reversible communication , central controller can connect from indoor side or outdoor side at will.
