LG has launched its fourth generation Multi V Water cooled IV HVAC system - available in heat pump and heat recovery versions from 22.4kW ~ 224kW
Accoridng to LG, its Multi V Water IV solution combines intelligent functions with advanced inverter technology boosting both energy efficiency and operational range no matter what the outdoor temperature and other environmental conditions.
The water-cooled system is claimed to provide return on investment (ROI) with a 5.9 coefficient of performance (COP) and an independent part load value (IPLV) of 6.73.
The design of the compact, lightweight outdoor unit enables double stacking, which results in a claimed 50% savings on installation space and the unit is easier to transport and install thanks to a 13% reduction in unit size and 15% reduction in overall weight.
LG says that by adopting a water-based cooling method, this unit optimises performance in comparison to compressor capacity. It also ensures heat exchange performance for high-rise buildings, thus allowing electrical savings.
Multi V Water IV uses underground heat sources such as soil, ground water, lake, river and so on as a renewable energy source for cooling and heating and a front-side connectable refrigerant and water pipe add to ease of installation. Water or antifreeze solution is circulated through the closed loop High Density Poly-Ethylene (HDPE) pipes buried beneath the earth’s surface.
