High Efficiency DC Inverter Compressor

The high pressure chamber offers high refrigerant volume efficiency with minimal suction refrigerant superheat. It also has a large refrigerant discharge buffer volume, resulting in low vibration and noise levels.

To achieve superior performance, the chamber utilizes a neodymium permanent magnet rotor, which provides strong magnetic force, high torque, and excellent efficiency. Additionally, the concentrated winding design enhances low frequency efficiency.

High Efficiency DC Motor

The high-efficiency DC fan motor is produced by a reputable brand. It boasts low noise and high efficiency, thanks to its high-density wire winding engineering. Additionally, it is a brushless motor with a built-in sensor.

180˚ Sine Waveform Control

By employing the ideal combination of 180˚ Sine waveform rotor frequency drive control technology and superior IPM (Interior Permanent Magnet) inverters, the motor achieves a remarkable 12% increase in efficiency. This synergy effectively minimizes reactive loss associated with motor-driven operations, resulting in enhanced overall motor efficiency.

Supercooling Flow Path Design.

The supercooling flow path design is implemented to separate the refrigerant inlet and outlet, which leads to an increase in the supercooling degree. This design effectively reduces the impact of high-temperature inlet gas refrigerant on the low-temperature outlet liquid refrigerant. As a result, the system experiences a significant boost in efficiency.

Refrigerant Cooling Design for Electric Control

The inclusion of an integrated electronic control board reduces the likelihood of failures occurring within the system. Additionally, the presence of a refrigerant cooling function ensures that the electric control components operate optimally by maintaining the ideal working conditions.

Cross Flow FIns

The system exhibits low air resistance, allowing for smooth airflow. Moreover, it features a great heat transfer coefficient, enabling efficient heat exchange. In addition, the system incorporates enhancements in frosting prevention. The heat exchanger is designed to distribute frost evenly, simplifying the defrosting process.

CCT Inner-grooved Tube

The CCT (Continuous Cooling Transformation) inner-grooved copper tube possesses excellent thermal conductivity. Its inner-grooved fins effectively disrupt the boundary layer of the refrigerant flow, resulting in enhanced refrigerant disturbance and improved heat-exchanging efficiency.

2-in-1 Refrigerant Flow Path Design

The 2-in-1 refrigerant flow path design has a significant impact on the system’s performance. It allows for a substantial increase in the proportion of liquid refrigerant volume in the condenser outlet. As a result, the indoor unit can generate a greater amount of heat or cooling capacity, enhancing its overall efficiency and performance.

Stepless Control

The DC fan motor is equipped with a stepless control mechanism that is regulated by the outdoor PCB (Printed Circuit Board) based on the system’s operating temperature. This intelligent control allows for precise adjustment of the fan motor’s speed, reducing energy consumption while ensuring the system operates at its optimal performance level.

Optimized Internal Structure

The optimization pipeline design contributes to a significant reduction of 5% in pressure drop within the system. This reduction leads to improvements in both Energy Efficiency Ratio (EER) and Coefficient of Performance (COP). The increased evaporating temperature and decreased workload of the compressor contribute to the enhanced EER and COP values, resulting in improved overall system efficiency.

Unit Applications

  1. Residential Buildings: This includes single-family homes, apartments, and condos. The ability of the system to provide zone control allows different areas of the home to be heated or cooled independently, increasing comfort and reducing energy use.
  2. Small to Medium-Sized Commercial Buildings: This could include offices, retail stores, restaurants, or small hotels. The system’s high efficiency and reliability make it suitable for these environments, where a consistent temperature is often necessary for comfort or even for the operation of the business.
  3. Educational Institutions: Schools, colleges, and universities can benefit from the zoning capabilities of the system, as different rooms or buildings may have different heating and cooling needs.
  4. Healthcare Facilities: Hospitals, clinics, and other healthcare facilities often have specific temperature requirements, and the precise temperature control offered by this system could be beneficial.
  5. Historical Buildings: In buildings where the installation of ductwork is not feasible due to architectural constraints, VRF systems can be an effective solution due to their flexibility in installation and minimal space requirements.
