When the ambient temperature reaches the limit condition, the heat exchange capacity of the outdoor unit declines, and the air return volume of the compressor is reduced, accompanied by problems in compressor suction and discharge protection. The TICA TIMS VRF unit adopts the high efficiency EVI system and cooperates with TICA's new inverter control and refrigerant system. In the unit, refrigerant is added through the air jetting port to increase the displacement, so as to broaden the cooling and heating ranges of the unit, enhance the overall capacity by 20%. In addition, the added refrigerant is injected into the pressure chamber of compressor to reduce the compression ratio and power consumption of the compressor, and improve the COP value by 10%

The ODU fan motor adopts the DC inverter motor that features an 45% increase in efficiency and substantial decrease in power consumption. Stepless speed control of the fan based on environmental conditions and air conditioner load, together with the stepless inverter technology of compressor, can achieve highly precise control for more stable and reliable operation.

TICA inverter VRF ODU adopts the efficient heat exchanger to achieve 12℃ stage-1 super-cooling, and 20℃ stage-2

The ODU heat exchanger adopts the φ 7.0 internal thread efficient heat-conducting copper tube and new aluminum fin, as

The specially designed TWO-TO-ONE refrigerant loop can effectively increase the amount of liquid refrigerant. As a result, less resistance to refrigerant flow can increase the comprehensive coefficient of heat transfer and further optimize the system.
