Mitsubishi Electric says its new City Multi YNW models are the cheapest to install and operate and offer the lowest CO2 emissions of any current VRF system.

The company adds that improvements mean the range delivers ultra-quiet noise levels, increased performance and a reduced footprint.
Jordan Jeewood, City Multi product specialist at Mitsubishi, said: “The new City Multi YNW models deliver the lowest installation costs, the lowest running costs and the lowest CO2 emissions currently available in a VRF system.’’

The YNW outdoor units include a new 4-sided heat exchanger to maximise the space available for plant by reducing the area required for air conditioning modules. Improved compressor and fan design also help to reduce sound power, making the YNW one of the quietest VRF systems on the market.

Jeewood adds: “We’ve looked at how to improve the system in almost every area and this means improvements across the board. In the case of our most popular 34kW model for example we see a 19% increase in seasonal efficiency, making compliance with energy legislation easier to achieve.

Easier maintenance
“We have increased the amount of cooling capacity that can be delivered per square metre of plant by 28% thanks to the advanced wrap around heat exchanger. This means less space is needed for outdoor modules and greater flexibility in where they can be located.”

The new models are available in capacities from 22kW to 150kW to offer some of the highest levels of efficiency coupled with smaller footprints, reduced noise levels and increased design options.

City Multi’s heat recovery two-pipe option also allows for phased installation, meaning that the cooling and heating system can be installed around a project build, with individual sections commissioned as required.

Up to 50 indoor units are connectable to the larger outdoor unit models and a complete new range of Branch Controller (BC) boxes is now available with reduction in height, a removable drain pan and a reduced refrigerant charge.

A completely new piping layout for the Branch Controllers (BC) boxes also increases the options for designers and installers and can help reduce installation time and make maintenance regimes easier.
