Working Principle

The VRF air conditioners, also known as "one-to-many," is a type of system where one outdoor unit is connected to several indoor units. Each indoor unit can operate independently or be controlled together. The system has an outdoor unit connected by pipes to indoor units that have components like outdoor heat exchangers, compressors, and other parts. The indoor units consist of fans and direct cooling elements. Using the pipes, the outdoor unit can supply cooling liquid to many indoor units. It controls the compressor's cooling fluid circulation and the flow into various indoor heat exchangers to meet the indoor cooling and heating needs.

The system's working principle is simple: the indoor temperature sensor controls the valve on the indoor unit's cooling pipe. By adjusting the pressure, the system can control the outdoor unit's compressor speed or change its operating mode to adjust the cooling capacity according to the load.

The multi-unit system has some key features:

Significant energy savings: The system adjusts the compressor speed and refrigerant flow automatically to operate more efficiently, reducing energy consumption during lighter use and lowering overall costs.

Space-saving design: The outdoor units, usually installed on the roof, take up no extra space. With just refrigerant and water pipes, the system's layout can save on building height and costs compared to water systems.

Easy installation and reliable operation: Compared to centralized water systems, the multi-unit system has a simple setup, making it suitable for homes. With fewer components, the system runs reliably and safely.

Meeting different room requirements: The system can be arranged to meet various room needs. In some setups, while some units cool, others can heat simultaneously. In winter, the system can cool one area and heat another, reducing energy consumption and meeting diverse air conditioning needs.

1. Nominal cooling capacity is determined according to the following conditions: Indoor temperature :27.0℃ DB/19.0℃ WB, outdoor temperature: 35.0℃ DB, equivalent pipe length: 10m, difference of height: 0m; 2. Nominal heating capacity is determined according to the following conditions: Indoor temperature: 20.0℃ DB, outdoor temperature 7.0℃ DB/6.0℃ , equivalent pipe length 10m, difference of height: 0m; 3. The noise level is tested before delivery. In the actual use, the measured noise may be different from the value specified in the table; in the quiet mode at night, noise is reduced by 5-8dB 4.
