World advanced 180° sine wave DC Inverter control Technique
Fully loaded with the newest technique, LARK takes the lead in researching and developing 180° since wave inverter control technique in China while it operates 120° rectangular wave BLDC variable speed control technique, which roundly improve the efficiency of inverter air conditoiner making the all-year round cost greatly lowered, and its operation is quieter.
DD s UPM
Digital DCBL Since Wave Universal Intelligent Power Module has the air conditioning system function control, electronic expansion valve control and thermodynamics optiomization control, etc many items of technical intergrations, which realized compact size and versatility.
Efficient PM fan motor
Adopting DC PM motor, efficient and saving energy, the fan adopts stepless speed changing to change according to outdoor temperature or load and realize reliable refrigerant pressure control.
Efficient PMSM compressor
Adopting different compressor control technique to general BLDC and innovating in using sine wave control calculation method, thus it is efficient, saves energy and greatly reduces the motor's noise.
Oil equalizing valve
Advanced oil return technique guarantees the operation effect of system to the ulmost extent under the precondition of guaranteeing oil equalizing between compressors.
Aero grille
The aero grille adopts such technique that guarantees the direction and strength of air having very small pressure loss.
Pressure sensor
Monitoring the working condition of unit at real-time, thus keeps the unit in optimal operation.
Heat exchanger
Adopting cross arrangemnet heat exchanger, thus effectively reduce the load of cooling operation.
Electronic expansion valve
Capillary is replaced with electronic expansion valve, which makes the air conditioning system be able to optimize energy and capacity distribution more precise.
Piping
Adopting straightforward piping connection design.
