Multi‑talented

LG Electronics Australia (LG) has announced the availability of its Multi V Water 5 air solution, which the company says delivers convenience and flexibility for a variety of Australian businesses.

The Multi V Water 5 is intended for commercial spaces. It is designed to offer efficient operation and convenient installation, as well as powerful cooling and heating within a compact design. Various configurations are available to suit a range of commercial buildings.

According to LG, the key heating and cooling features include geothermal applications, which use underground heat sources such as soil, ground water, lakes, and rivers to produce renewable energy for its cooling and heating systems. This results in delivering enhanced temperature control that is less affected by external conditions.

“Our new Multi V Water 5 is a reliable commercial air solution for a variety of buildings and spaces, providing businesses with optimal comfort for all work environments,” says LG’s Andrew Barron. Go to www.lg.com/au ■

8 Siemens connects

Siemens Smart Infrastructure has launched Connect Box, which the company says is “an open and easy-to-use” IoT solution designed to manage small to medium-sized buildings.

“The latest addition to the Siemens Xcelerator portfolio, Connect Box is a user-friendly approach for monitoring building performance, with the potential to optimise energy efficiency by up to 30 per cent and to substantially improve indoor air quality in small-to-medium-sized buildings such as schools, retail shops, apartments or small offices.

“Siemens Xcelerator is an open digital business platform that enables customers to accelerate their digital transformation easier, faster and at scale.

Siemens says Connect Box allows users to accomplish essential daily building management tasks from one place via a cloudbased interface, with no additional gateway or software.

Alarm notifications for potential issues as well as graphics that visualise historical trends provide meaningful insights into the building performance at any time, supporting the optimisation of building operations.

Serving Up Home Hot Water

A UK company is rolling out small but powerful servers that can be attached to home hot water heating systems. The servers receive the cooling they need, and the householders who install them get free hot water heating in return. The installation works by fitting the server and a patented thermal bridge to a standard 450mm diameter domestic hot water cylinder. When the server generates heat during processing, it transfers this via the thermal bridge to the water in the cylinder, meaning that less energy is required to bring the water to temperature.

Heata, the company behind the initiative, says the unit will provide a useful base load of heating.

“If it ran all day, it would deliver about 4.8kWh,” says Heata, “which is about the amount of hot water an average household uses.”

Heata notes, however, that in practice the utilisation level will be lower, and sometimes the water will already be at temperature, so the unit won’t run. ■
