Inverter Rotary compressor and ECO R32 refrigerant for max heating capacity and less refrigerant necessary, large amount of latent heat from the air via evaporator in even worst weather.
B.Ultra frequency conversion technology
Based on the principle of proportional relationship between motor speed and input frequency of working power supply: n = 60f(1-s)/p and changing motor speed by changing working power frequency of the motor, it adopts AC-DC-AC power conversion technology, relying on our powerful control system with PWM generation ability, integrate V/F, vector control (VC) and direct torque control (DTC) to achieve control method of variable frequency PID calculus, mainly drive variable frequency by way of PWM synthesis drive, fully integrate power, electronics, microcomputer control and other technologies.
C.Advanced Carel Operate System, ultra intelligent
Especially superb heat dissipation circuit board design, longer service, over 3 times of other brands', simple click and fully
achieve the excellence of DC inverter conversion system for outstanding performance.
D.Multi-speed mute fan motor
ROHS fan blades, ultra-low noise, durable & reliable, constant max air flow to satisfy heat supply.
E.Soft-start and soft-shutdown
Protecting both electrical system and other key parts, such a EEV, SANHUA 4-way valve, LG AC contactor & other World famous brand components to ensure the heat pump device 2-3 times longer service by
1) making output torque of the motor meet the requirements of mechanical system for starting torque, guaranteeing smooth acceleration & transition, and avoiding destructive torque impact;
2) modulating starting current to fit the motor's bearing capacity, and avoid the insulation damage or burnout caused when it starts.
3) reducing both voltage sag range and the content of high-order harmonics etc.
F.High-tech shock-absorption all copper construction piping
High-accurate completely automatic silver welding, easy maintenance.
G.High-density protective jacket for minimum heat lost
Aviation class insulation foam with outstanding sound absorption.
H.Classic European outlook forming
Fashion taste, never out of time.
I.Portable compact design
Saving room for installation & operation.
J.Fast heating and cooling speed
Before the indoor temperature reaches the set value, the Panasonic rotary compressor operates at high power, enabling the unit to work at high frequency so that it can heat water or provide house heating/cooling at a faster speed.
