VHX Series Line up

Features High Energy Efficiency Brushless DC Motor High Efficiency Low noise DC Inverter Compressors High pressure type Asymmetric scroll design Neodymium permanent magnet rotor 180 Sine Wave Control High precision Rotor Speed control 2-in-1Refrigerant Flow Path Increase the liquid refrigerant volume proportion Stepless Control On-demand output, high efficiency and energy saving Supercooling Design Enhance the supercool of refrigerant to increase system s efficiency CCT Inner-grooved Tube Excellent heat-exchanging efficiency Cross Flow Fins Reduce air resistance Frosting improved

Features High Efficiency Compressor High pressure chamber VHX-X series adopts high-pressure chamber scroll compressor This type of compressor has an interior oil separation section which maintains most of lubricating oil in compressor by the use of interior oil moist separator and oil-returning pipe design Differential pressure oil film control technology, reducing noise and improving gas tightness Concentrated winding, improving low frequency efficiency DC Inverter Scroll High strength bearing, high rigidity shell

Features High Efficiency Compressor Asymmetrical Scroll Technology Asymmetric scroll structure of compressor effectively helps reduce the refrigerant gas leakage loss in the process of suction and compression. Make sure the operation stability and further improve the system efficiency.

Features High Efficiency DC Motor High efficiency DC fan motor is from well-known brand Low noise and high efficiency because of high-density wire winding engineering Brushless with built-in sensor Low efficiency Big noise Not adjustable AC Motor

Features High Energy Efficiency 2-in-1 Refrigerant Flow Path Design Liquid refrigerant volume proportion in the condenser outlet is highly increased, so the indoor unit's will produce more heat (or cool). Gas phase Liquid phase Gas phase Liquid phase Increase the liquid refrigerant volume proportion Conventional design 2-in-1 Refrigerant Flow Path Design

Features High Energy Efficiency Subcooling Flow Path Design We separates the refrigerant inlet and outlet to increase the subcooling degree. That is to reduce the effect of high temperature inlet gas refrigerant to low temperature outlet liquid refrigerant, therefore, the system efficiency will be greatly increased. Inlet and outlet are too close. Inlet and outlet are separated. Conventional Flow Path Subcooling Flow Path Design
