MHIE provides an air of improvement

Mitsubishi Heavy Industries Europe (MHIE) has announced an expansion to its KX6 VRF (Variable Refrigerant Flow) range of air conditioning systems, offering what it claims is an 'industry-leading' combination of efficiency, flexibility of installation, and compactness. Eight full-size KX6 heat pumps in the range 33.5 kW-68 kW have been launched, which can be paired to configure systems up to 136 kW. The new higher output models offer smaller dimensions, making the units easier to transport. They can be installed and maintained more easily where space is at a premium. KX6 is claimed to achieve Class A ratings for energy efficiency, with Coefficients of Performance up to 4.33. New compressors, heat exchangers and inverter controls contribute to the increased efficiency.

A world away from R22

Oasis fashion stores and optician Vision Express are reaping the financial benefits of replacing inefficient air conditioning units with high efficiency inverter systems from Mitsubishi Heavy Industries Europe (MHIE). Supplied through 3D Air Sales, a refit of selected stores provided the ideal opportunity to replace equipment that uses ozone-depleting R22 refrigerant ahead of the ban, which came into force on 31 December for virgin HCFC. MHIE technology uses what's claimed as environmentally-friendly R410a refrigerant, said to have zero Ozone Depletion Potential. The latest MHIE systems also have much better heat transfer properties, reduced refrigerant requirements and reduced energy consumption. The R410a inverter climate control systems were installed by Air Conditioning Economics of Derby.

VRF in a tight spot

Confined space for outdoor units meant a KX4 VRF heat recovery system from Mitsubishi Heavy Industries Europe (MHIE) was ideal for a new office building on Humberside. Six outdoor units, delivering a total of 327 kW, were fitted into a tight plant space and provide heating and cooling through 127 ducted indoor units in the two storey building. Manager of Air Conditioning Economics (ACE), Alan Ball, says the compact footprint of the units, combined with reliability and price, made an MHIE system the obvious choice.

Cambridge passes exam

Cambridge University's Department of Engineering has gained a high degree of control over office heating and cooling with a new heat recovery system from Mitsubishi Heavy Industries Europe (MHIE). The VRF solution, supplied by 3D Air and installed by Adcock Refrigeration and Air Conditioning, replaces an outdated air conditioning system in loft-space offices. The three-pipe system from the KXR6 ecolution range provides simultaneous heating or cooling of individual indoor units, and maximises energy efficiency through recovery and redistribution of surplus heat from cooling operations. Adcock's team worked with Kershaw Mechanical Services of Cambridge to provide a system that would offer greater controllability, reliability and energy efficiency.

Combination hits the right temperature for office refurb

A major office refurbishment of Lockton House in Cambridge includes the use of inverter technology from Mitsubishi Heavy Industries Europe. A combination of KX VRF and split systems from the company's ecolution range was supplied by FM Air and installed by Adcock Refrigeration and Air Conditioning. The inverter-controlled systems adjust compressor output to match the cooling or heating demands of the indoor units to save energy and eliminate temperature fluctuations. The firm's low profile KX6 outdoor units also met the project's planning constraints, says Martyn Foreman, manager of Adcock's Cambridge branch: "At just 854 mm high, KX6 heat pump condensers fit the limited wall mounting space below the building's window level, so they don't obscure views of the historic city".

Keeping GP practice cool

Chatfield Health Centre, a busy inner London GP practice, found that its purpose-built premises were very hot in summer months, and called in "high-efficiency" air conditioning systems from Mitsubishi Heavy Industries. Addressing a tricky outdoor siting, Aircon Worldwide designed, specified and installed compact units from MHIE's KX and split ranges, offering 66.6 kW. Comfortable air temperatures all year round, not just in summer, will make visits to the doctor easier for patients, as well as creating a better working environment for medical and clerical teams. Aircon Worldwide says that the design of the building ruled out a single large system to serve the 20 rooms requiring air conditioning. "There was nowhere to put more than one VRF-type outdoor unit," says the firm. The solution decided upon was to install five independent systems, "which would not spoil the appearance of the building". A single 28 kW FDCA280 KX4 heat pump was added to two 14 kW FDC140 ecolution KX6 heat pumps, a 5.6 kW SKM35X2 twin-split and a 5 kW SRK50 single split. There are two cassettes and 22 wall-mounted units.

Complete system for hotel

The Icon, Luton's newest four-star hotel, is ensuring energy efficient climate control with a Variable Refrigerant Flow (VRF) heat recovery air conditioning solution and a range of Split Systems from Mitsubishi Heavy Industries Europe (MHIE). A VRF system from MHIE's Ecolution HyperMulti KX6 range will serve 34 guest rooms, while high performance Split Systems from the FD Series are being installed for ground floor facilities. The VRF and Split systems feature advanced inverter technology which adjusts compressor output to match the cooling or heating demands of the indoor units to save energy and eliminate temperature fluctuations. MHIE's new RCH-E3 control solution, completes the hotel's air conditioning package. Each room has a controller, linked to the hotel's Building Management System (BMS). Designed for use in hotel rooms, the RCH-E3 includes an easy-to-read panel for temperature control.

No-fuss R22 replacement

With the imminent ban on virgin R22 refrigerant, Mitsubishi Heavy Industries Europe (MHIE) has confirmed that its high-efficiency R410a split systems can be installed in place of most makes of old R22 indoor and outdoor units, without the need for new pipework or wiring. Due to refrigeration legislation, R22-based equipment has been banned since 2004, and for the five years after 31 December 2009, only reclaimed or recycled R22 can be used to recharge system still in use. After 2014, no R22 recharging will be allowed and any remaining systems will be regarded as unservicable. MHIE’s R410a split system has several benefits over the old R22, which include high CoP (Coefficient of Performance) ratings, enhanced heat transfer properties, reduced refrigeration requirements and reduced energy consumption, up to 38 per cent less than older models, says the firm. The R410a replacement system uses existing pipework and wiring, allowing the system to be installed quickly and easily, with minimal disruption, says the company.

Ford is keeping its cool

Mitsubishi Heavy Industries Europe's (MHIE) VRF and split systems have been installed at the new Allen Ford facility in Swindon. Selected for reliability, performance and price, the units are; "compact, economical and energy efficient," according to MHIE. John Needham from installers, Cooling Techniques said: "I have used MHIE equipment on numerous projects – it combines high quality with good process, and has never let me down". The showroom and meeting room is cooled by seven FDUM ducted systems in single split configurations, and is cooling rated at 7.68 kW and 12.95 kW (up to 9 kW and 16 kW heating). Part of MHIE's ecolution range, these inverter-controlled systems offer energy savings of up to 38 per cent.

MHIE adds fine air to fine wining and dining

Compact, energy efficient MicroKX VRF systems from Mitsubishi Heavy Industries Europe (MHIE) have provided an air conditioning solution for a new London restaurant, High Timber. According to the firm, the MicroKX is the smallest, most energy efficient mini-VRF system available, but it provides "big system" air conditioning benefits, such as flexibility, control and connectability. applications. The four 15.5 kW MicroKX outdoor units, which are installed in the restaurant's ventilation room power the eight indoor units (four 4-way FDT cassettes of 7.1 kW and four FDK units of 7.1 kW).

Compact heating and cooling

The small footprint, high efficiency new generation VRF systems from Mitsubishi Heavy Industries Europe (MHIE) are proving an "ideal" heating and cooling solution for Newcastle's Haymarket Metro office/retail redevelopment. There are no large flat roof spaces in the design, so plant area had to be kept to a minimum. MHIE's KX VRF system was specified for the varied spaces, thanks to its compact size and energy efficiency. The nine MHIE KX VRF systems are concealed from view at street level. The units feed 68 indoor units – which are a mix of cassette and floor standing variants. Floor standing units are used on the upper storey as there is no ceiling space for built-in indoor units.

Air of efficiency

A 1 MW VRF air conditioning system from mitsubishi heavy industries europe (MHIE) has been specified to meet the demands for operating efficiency, limited outdoor space and low noise, for a prestigious office development under construction in Gallowgate, Newcastle-Upon-Tyne. MHIE distributor 3D Air worked with consulting engineer Hoare Lee to plan a system which would meet the project's exacting specification, including minimising any loss of capacity due to long pipe runs. A KX4 system was selected which consists of 320 indoor units and 18 external condensers for over 10,000 m2 of floor space.

A hotter proposition

Substantial technical improvements place the new wall mounted SRK-ZIX inverter heat pump single splits from Mitsubishi Heavy Industries Europe (MHIE) among the top performers in air conditioning efficiency, claims the company. New models produce better Energy Efficiency Ratings (EER) for cooling and Coefficient of Performance (COP) for heating, with ratings in the range of 5.71 and 5.56 respectively. There are five models in the range, designed for small commercial or residential applications, with a choice of cooling and heating capacities. All models are supplied with anti-allergen and deodorising filters for a healthy environment. The indoor units are complemented by MHIE's SRC-ZIX outdoor units which can be sited up to 15 m from the indoor units with up to 10 m height separation for smaller units. David Lettis, sales manager for MHIE commented: "These units have been designed to be best in their class, and the performance figures confirm this. Compared to the previous range, all models are more efficient".

MHI multi-splits are first choice for Age Concern

Two of Mitsubishi Heavy Industries' FDC250V outdoor units have been fitted at Age Concern's activities centre in Barking, Essex. The two outdoor units provide a maximum cooling capacity of 28.0 kW, connected to eight FDT60 cassettes in the centre's activities room and food hall. Mitsubishi Heavy's FD series offers air conditioners with cooling capacities from 4.0 to 28.0 kW as single split systems and connectable as multi-split systems from 7.0 kW upwards. FDC models can be linked to up to four indoor units, with the option of different unit combinations, connecting to a single FDC inverter. All FD systems include a wired remote controller, the RC-E3, which has a programmable weekly timer as standard. Ben DiSapia, contracts manager at installers Birdsall's, had no hesitation in specifying Mitsubishi Heavy's products: 'MHI's multi-splits are good kit - they do everything you want them to do, and they can't be beaten for value for money'.

Chilling out in hotels

An easy-to-use air conditioning controller, specifically designed for use in hotel rooms, has been introduced by Mitsubishi Heavy Industries. The RCH-E3 controller has been proven in use with Mitsubishi's VRF systems. The controller has features of the RC-E3, but only the simple functions which a hotel guest will need. Offering control over on/off operation and fan speed, it also prevents the user from setting excessive temperature settings, thus maintaining the efficiency of the unit. Room temperature will either remain at the user's setting, or can be automatically returned to a predetermined temperature setting by the hotel's Building Management System. Mitsubishi Heavy's UK sales manager, David Lettis commented: 'Simplicity and ease of use are high up the feature list in hotel applications, and the new RCHH-E3 controller provides exactly that. Hotel guests want air conditioning which they can adjust with a couple of touches of the button, rather than a system with advanced features they don't need, or fully understand without calling the front desk. And hotel management want to be able to set up a system for maximum efficiency without users being able to override important functionality, either by accident or design'.
