We continue a series of publications about how LG Electronics operates in Russia, and, in particular, about the LG MULTI V air conditioning systems supplied to our market.
Below we describe a joint project between LG Electronics Commercial Air Conditioning and Delta Controls. One of Delta Controls’ offices has been fitted with LG’s MULTI V multi-zone variable refrigerant flow air conditioning system, which is a unique combination of high performance, environmental friendliness and economy.
The main advantage of the MULTI V system is the state-of-the-art technical solutions underlying it, which provide ease of installation, comfort and safety of everyday use. The indisputable advantages of MULTI V systems also include the diversity of their model range: outdoor units are available in 4 versions (MULTI V Plus, MULTI V Sync, MULTI V Space, MULTI V Mini), and indoor units have as many as 14 varieties, which allows you to use LG products Electronics for creating a microclimate in residential and public buildings of any size and functional purpose.
The MULTI V Mini system was chosen for installation at the Delta Controls facility. The MULTI V Mini system is designed specifically for air conditioning small offices, residential areas and detached buildings. Its main characteristics are compactness, high energy efficiency and low noise level.
The compact dimensions of the outdoor units can significantly save space (MULTI V Mini systems take up 46% less space than conventional air conditioners). Up to 9 indoor units can be connected to one outdoor unit in this system, which can be located at a very significant distance from it and from each other. The total performance index is 130%. Of particular note is the manufacturability of the design of the outdoor units of this modification. Thus, shut-off valves are located inside the body, which not only gives them a modern appearance, but also allows pipelines to be supplied from any of the four sides. Convenient handles make it easy to transport the equipment. And the design of the case provides for convenient maintenance: to diagnose the system, you need to unscrew only 3 screws.
The Delta Controls office is equipped with a centralized utility management system based on the BACnet protocol, which allows you to create a single environment for the collaboration of HVAC, lighting, life support, power supply, elevators and other building control devices, regardless of the manufacturer. The MULTI V system was integrated into the overall building management system using the LG BACnet supervisory system. Thanks to this module, system parameters can be accessed from anywhere in the world through the built-in web server, and system energy efficiency can be monitored using the energy meter.
Block for connecting to the network infrastructure of the building
Provides easy communication between LG air conditioning system and BMS system
The BACnet unit and the LG supervisory system are controlled through the ORCAview program, which combines the ease of use of mimic diagrams with the power of a real-time system tool.
The MULTI V system was successfully launched at the Delta Controls site in March 2011.
