A basic VRF system comprises one outdoor unit with one inverter VRF compressor and multiple indoor units. The inverter compressor provides high-efficiency cooling and heating at partial loads. Sometimes several outdoor units can be combined into a single system that can be connected with 60 or more indoor units. 

Compared to conventional chillers and air conditioning systems, the VRF system offers a number of advantages, such as individual room control, thanks to the innovative technologies. 
The ever-widening variety of VRF applications ranges from large commercial offices to small shops and even private houses. The compact outdoor unit will fit into a confined space, while attractive indoor units can embellish your room interior. These are the benefits of the new VRF generation. VRF systems also offer game-changing energy efficiency in the air conditioning market, being able to control each individual room instead of cooling or heating the entire building. 
Thanks to the compact outdoor unit, mini VRF systems gain popularity among shops in congested urban areas, since they do not require much installation space.

The projects that previously used chillers now can use a VRF system instead. 
Nowadays, with the pandemic being around for years, the customers increasingly look to the solutions that protect human health and life. The VRF air conditioning systems have evolved from maintenance of comfortable temperatures to securing safety of human health and life, with air purification and fresh air supply features becoming particularly important. Many manufacturers undertake research and market products of this kind. The ventilation problem is solved by installing VRF systems with the air purification feature. Fresh air purification systems using conventional heat exchangers ensure good indoor air quality (IAQ), while consuming less power. 

The market of commercial air conditioners, including VRF systems, recovers slower than sales of residential air conditioners. When the pandemic just started, many national governments restricted people’s movement, and the manufacturers started taking their corporate customer relations online. However, these means of communication limit the possibilities of attracting new customers and identifying new demands. Another thing to be considered is the sweeping trend towards limiting carbon emissions into the atmosphere, which offers opportunities both for business and environmental protection. 
Although the global VRF market was severely affected by the pandemic in 2020/2021, these systems are well-positioned for quick recovery of the sales, since the VRF solution has unique technical advantages over its competitors in the market.

One of the manufacturers of VRF systems is the Haier brand. You can see the range of VRF systems from Haier by following the link.
