LG has launched a new range of VRF air conditioning products designed for commercial buildings, office complexes and large retail outlets.
The Multi V III is claimed to offer three key benefits; higher energy efficiency, larger capacity and longer piping lengths.
MULTI V III uses various low noise technologies to minimise operation noise, namely a compressor with BLDC motors, low noise fan motors and a newly developed shroud shape.
Energy efficiency is boosted by LG’s BLDC V-Scroll inverter compressor with High Pressure Oil Return technology, (HiPOR) superseding the previous model’s AC motor. HiPOR delivers a COP of 4.58 for heating and 4.27 for cooling, an improvement of 11 per cent and 25 per cent respectively, one of the highest in the industry.
Another advanced feature is Multi V III’s continuous heating system, which maintains a pleasant indoor temperature with minimal heat loss when defrosting the outdoor unit.
Contractors will find that with an increased piping length of up to 1,000m and 20HP capacity per unit (up to a maximum of 80HP) it is possible to connect up to 64 indoor units using configuration. This allows a variety of designs to be tailored to individual building needs. Up to 200 per cent efficiency can be achieved using different combinations.
For example, when designing a HVAC system with a total capacity of 400 HP, the 80 HP MULTI V lll combination gives the following benefits when compared to conventional 40 HP combination models:- reduced installation space and piping lengths by up to 50 per cent and the pipe shaft space by up to 30 per cent.
