Reduced Carbon Footprint
from New, More Powerful
City Multi Range
Our latest range of R410A City Multi range
boasts much more powerful outdoor units
that not only reduce energy consumption and hence, carbon footprint, but they are much smaller too, reducing the space required in which to fit them.
The range also offers design flexibility combined with industry high COPs of 6.1.
As part of our Green Gateway Initiative to provide more energy efficient solutions to meet the demands of the industry, we have designed a new range of powerful R410A outdoor condensing units that are smaller, shorter, lighter and more powerful. These offer customers a way of reducing both the space needed to install our systems whilst providing great reductions in the overall energy consumption in their building.
Our new City Multi YHM range boasts an average 45% reduction in footprint over previous models (for the 14-18HP units), a 16% reduction in weight and has 13 different sizes in its line up. The smaller outdoor unit can fit through an 800mm wide door and be carried in an average 6-person lift, making it ideal for inner-city areas where transport to rooftops by crane is restricted.
“Our latest models achieve an industry-leading weight saving without compromising on performance, boasting the highest COPs (Co-efficiency of Performance) available,” explained Philip Ord, Product Marketing Manager for Mitsubishi Electric.
The YHM range includes unique simple ‘Replace’ models, which extends our Green Gateway Initiative into the commercial sector whilst offering customers a quick and straightforward way of improving system performance and reducing their carbon emissions.
The Green Gateway Initiative is the company’s bold plan to help the country reduce overall energy consumption in the built environment. “We have sold over 75,000 kW of comfort cooling R22 systems up until 2002 and many of these systems are ready for an upgrade. Installing our YHM with its unique Replace function can help reduce power consumption by up to 60% leading to a significant reduction in CO2 emissions,” explained Ord.
“These thousands of 10-15 year-old VRF systems that use R22 refrigerant are coming to the end of their useful life and the YHM system offers a straightforward way to safely remove this ozone-depleting refrigerant, whilst improving performance and energy efficiency for customers.”
Existing piping can also remain in situ and be reused to dramatically reduce both installation time and cost, with the added benefit that the system will need much less raw materials such as copper, leading to even greater CO2 savings. The all-new line up has specially designed components to increase performance. New wrap around coil and heat exchanger designs offer greater system efficiency and the 100% inverter control units, available in either heat pump or heat recovery offers the highest efficiency currently available in this format with seasonal energy efficiency ratios (SEERs – as recommended by Part L2 of the Building Regulations) as high as 6.26.
The YHM is available in a space saving model with an average increase in SEER of 8% above its immediate predecessor, and is also available as a high efficiency range averaging 18% higher SEER. This radical development is designed with the Green Gateway Initiative in mind to offer
customers a choice of energy efficient products.
“We have increased the total system pipe run to 1,000 metres and offer a furthest pipe length of 165 metres to ensure that the YHM range is one of the most flexible VRF systems available today,” added Ord. “Every aspect of the technology has been examined and improved to offer customers the most advanced product of its size currently available on the market.”
These improvements extend to both the indoor units – with an increased range and models such as the new ceiling cassette offering 72 different air flow patterns – and the associated tools. Newly designed for the YHM range is a refrigerant volume checking system to detect whether any possible leaks have occurred between regular services.
In combination with a dedicated new floor-standing ducted unit, the YHM range is capable of 60 Pa static pressure and offers a quick and easy way of retrofitting buildings that used to have radiators and which have no other space available for the air conditioning. The floor standing unit fits into the space left by the radiator and delivers an impressive air throw to give an even distribution of heat energy around the room that is similar to the convection flow from radiators.
“With the YHM range we have an exceptional line-up that is ideal for both new build and retrofit applications with a unique Replace system that enables customers to upgrade quickly and downsize emissions even faster,” ended Ord.
