Design of control condenser with electronic expansion valve

The condenser is controlled by two electronic expansion valves respectively, which can reasonably use the heat exchanger area according to the demand of IDU heat exchange temperature, distribute the refrigerant flow according to the load demand, to ensure high-performance heat exchange efficiency.

HIGH EFFICIENCY

Supper efficiency with full DC inverter com pressor

Matches up inverter with step less compressor, the durability and stability of the compressor are guaranteed, fault can be reduced.
Each compressor is adopted oil temperature sensor and the discharge temperature sensor, detecting the discharge temperature and oil temperature of compressor, cooperated with the compressor freguency and the EEV control, to ensure exhaust heat and oil temperature superheat kept within the optimal range. Ensure that the oil dilution is maintained at a safe level at all times.

Stepless inverter DC-motor

Outdoor unit matches efficient variable-speed DC-motor, drived by sine wave, wider efficiency range and torque range, motor efficiency is increased by 17%. air fan of outdoor unit can achieve 0~91 Hz stepless frequency.

New one-piece of four-way heat exchanger

SUPER COMFORT

Wide operation temperature

The heating operation temperature can be as low as -23°C, and the heating is more powerful in winter. The cooling operation temperature can reach 50°C, better in summer.

Intelligent triple backup operation technology

• For the twin-compressor system, when one compressor breakdown, the other compressor can be put into backup operation immediately to ensure the user needs.
• For the multi-module combination, in case of breakdown of one outdoor unit, this unit can be interrupted from the system so that the other modules can continue to operate.
• Super-long backup operation time, which can reach up to 8 hours.
