DC Inverter EVI Compressor​

The high-pressure chamber is a robust component designed to safely contain gases or liquids under high pressure.

Small suction refrigerant superheat refers to minimal superheating in the refrigeration system’s low-pressure side, improving the system’s efficiency by ensuring effective heat absorption and release.

Large refrigerant discharge buffer volume indicates considerable space on the high-pressure side of the system, reducing vibrations and noise by allowing smooth and stress-free expansion and heat release of the refrigerant.

High Efficiency DC Brushless Motor​

The high-efficiency DC fan motor originates from a reputable brand, ensuring quality and reliability.

Thanks to advanced high-density wire winding engineering, this motor delivers both low noise and high efficiency, making it a standout choice for various applications.

What sets this motor apart is its superior performance even at low speeds. It significantly surpasses traditional motors in operating efficiency, enhancing the actual operating efficiency by over 30% when compared to conventional counterparts.

DC Motor Stepless Control​

The system features high precision pressure control, achieved through the use of a high-precision pressure sensor. This allows for seamless regulation of the fan motor speed in accordance with the system’s operational status.

Additionally, it supports real-time load adjustment. This means the system can intelligently detect and control its operations, adapting in real-time to changing conditions and needs.

Night Time Noise Control​

During the night, the unit operates at a reduced capacity to minimize noise, ensuring a quiet environment.

Furthermore, the main Printed Circuit Board (PCB) allows for adjustments in the unit’s operations based on the time of day, providing customized day and night operational modes.

Refrigerant Cooling Design​

We employ a refrigerant to maintain the safe operation of the inverter modular board, ensuring its stability even when outdoor temperatures reach up to 55 degrees Celsius. This cooling method keeps the board within its safe operating temperature range, preventing overheating and potential damage.

All Outdoor Units Cycle Operation​

In our combination system, any outdoor unit has the capability to function as the master unit, with the start order shifting automatically as needed.

This design approach evenly distributes operational loads, promoting balanced wear and tear among the outdoor units in a system, and thereby extending their overall lifespan.

Backup Function​

Our system incorporates a module backup function. In the event that certain modules fail, others can continue to operate via simple settings adjustments.

The same redundancy applies to the compressor backup function. Should one compressor fail, another can carry on working seamlessly with straightforward setting changes.

Additionally, a fan motor backup function is included. If one fan motor fails, another can keep the system running by just adjusting the settings. This comprehensive backup mechanism ensures continuous operation and minimizes system downtime.

Long Pipe & Height Difference​

The specifications for the pipework and wiring in the system are as follows:

– The total pipe length for the system is 1000 meters.
– The longest individual pipe can extend up to 200/240 meters.
– There are certain height differentials to consider:
– If the outdoor unit is situated above, the height difference should be less than 100 meters.
– If the outdoor unit is positioned below, the height difference should not exceed 110 meters.
– The height difference between the indoor units should not surpass 40 meters.
– The length from the first indoor distributor to the last indoor unit should be no more than 90 meters.
– The communication wire for the system can extend up to 1000 meters.

Automatic Addressing​

There are two convenient methods available for addressing:

1. Automatic addressing: In this mode, the system automatically assigns addresses to each indoor unit, simplifying the configuration process.

2. Manual setting: This option enables users to manually set addresses using a wireless remote controller, offering more control and customization.

The preferred addressing method can be selected effortlessly by adjusting the switch located on the outdoor Printed Circuit Board (PCB).

Refrigerant Status Detection​

The system comes equipped with a smart refrigerant auto-check function. This feature assesses the status of the refrigerant and provides suggestions accordingly.

The refrigerant status is represented by different codes, each indicating a specific condition:

– Code 13: Indicates that the refrigerant is extremely insufficient.
– Code 12: Signifies that the refrigerant is insufficient.
– Code 11: Represents a slightly insufficient amount of refrigerant.
– Code 0: Suggests a normal refrigerant level.
– Code 1: Implies a slightly excessive amount of refrigerant.
– Code 2: Warns of an overmuch or excessive refrigerant level.

This intuitive coding system allows for easy monitoring and maintenance of the refrigerant levels.

E-part Adopt Integrated Technology​

The VMEP Series utilizes integrated circuit control technology, a modern approach that streamlines system design by reducing the amount of necessary wiring and the quantity of Printed Circuit Boards (PCBs). This innovative technology not only improves operational reliability but also reduces the chances of incorrect wiring connections, enhancing overall system stability and performance.

Service Window on Front Cover​

The inclusion of a service window greatly simplifies the process of monitoring and adjusting the outdoor unit’s status and settings. This user-friendly feature eliminates the need to remove the front cover, making regular check-ups and maintenance much more convenient.
