Product Description

VRF system: In the 1980s, inverter air conditioner technology began to be applied to multi-split products. The VRF (Variable Refrigerant Flow) system uses a combination of one outdoor unit and multiple indoor units to achieve more precise temperature control and higher energy efficiency. The VRF system has gradually become the mainstream of multi-connected products.
VRF multi-connection system: adopts frequency conversion technology, can provide different temperature and air volume control in different rooms, and save energy at the same time.

High-efficiency and energy-saving version of the multi-connection solution
It is suitable for users who pay attention to energy saving and environmental protection. The solution adopts high-efficiency frequency conversion technology, which can automatically adjust the intensity and frequency of cooling and heating according to the indoor and outdoor environment changes, so as to achieve better energy consumption control and air quality adjustment effects. The solution is also equipped with some high-tech functions, such as intelligent voice control, air purification, etc., to improve the user experience.
case:
In order to save energy and protect the environment, a large enterprise chose the high-efficiency and energy-saving version of the multi-connection solution. There are 20 rooms in the enterprise's office area, and each room is equipped with an indoor unit and a sensor, which can automatically adjust the intensity and frequency of cooling and heating according to changes in the indoor and outdoor environments. In addition, it is also equipped with a brand new air purifier, which improves the air quality.
