Mitsubishi Electric Changes Name of DeLclima to MELCO Hydronics and IT Cooling

TOKYO, March 22, 2016 - Mitsubishi Electric Corporation (TOKYO: 6503) announced today that DeLclima S.p.A., which Mitsubishi Electric achieved 100-percent ownership of on February 24, was renamed MELCO Hydronics & IT Cooling S.p.A., effective March 15.

The name change, which clearly declares the company's mission, also signifies to employees, customers and suppliers that the company has become an integral and valued part of the Mitsubishi Electric Group. Mitsubishi Electric aims to swiftly realize synergies and strengthen its commercial heating, ventilation and air conditioning (HVAC) business globally.

The acquisition of DeLclima represents Mitsubishi Electric's full-scale entry into the chiller1 business and will enable the company to further expand its business portfolio, which will be important in achieving continuous growth and increasing market presence. The acquisition will also allow Mitsubishi Electric to adequately respond to environmental regulations (F-Gas regulations2), which are expected to increasingly impact business practices in the coming years.

Mitsubishi Electric has a global presence in the area of heating, ventilation and air conditioning (HVAC) systems in markets such as Japan, Europe, North America, China, Southeast Asia, India and Australia. Europe in particular is an important market for Mitsubishi Electric after Japan. As the European air conditioning market matures, it further requires market players both to provide value-added products such as energy-saving products and to comply with environmental regulations, and in response, Mitsubishi Electric is growing its business in the region with a particular focus on room and packaged air conditioning as well as multi air conditioning systems for buildings.

  1. Chillers maintain the temperature of an object by utilizing a heat medium (e.g., water) in a loop system and as a general name refer to central air conditioning systems whose primary application is for large facilities such as buildings and factories.
  2. Regulations in Europe require the total emissions for Freon gas, a type of greenhouse gas, to be reduced gradually by 2030.



  • The benefits of refrigerant and water energy as energy sources combined in one system
  • Refrigerant circuit between outdoor unit and HBC controller
  • Water circuit from HBC controller to indoor units
  • Highly efficient solution based on 2 pipe system technology
  • Prototype already in use

Nuremberg / Ratingen, 9 October 2012 – At Chillventa 2012 in Nuremberg, Mitsubishi Electric presented a Hybrid City Multi system on the market for the first time, which combines the ,benefits of refrigerant and water as energy sources in one system. The tech-nology is based on the company’s VRF R2 system and consists of a City Multi series VRF R2 outdoor unit and a specially developed HBC controller, which distributes the refrigerant and shifts the heating and cooling energy. With the Hybrid City Multi system, energy is transferred from the refrigerant to water via two plate heat exchangers, which then supplies the indoor units from a central location in the building. The unit is already in operation as a prototype in the Ratingen-based manufacturer’s new administration building.

“Firstly, with this ground-breaking innovation we are meeting increasingly stricter requirements in terms of the F-Gas Regulation and thus the use of refrigerants. As with our new Hybrid VRF-system, we are kind of self-sufficient,” explains Michael Lechte, Marketing Manager of Mitsubishi Electric, Living Environment Systems. “Secondly, we can offer an impressive, highly efficient solution if for example a building has to be cooled and heated using water as the energy source.”

In this context, Hybrid City Multi technology uses the advantages of both a water and refrigerant conducting system. The high efficiency of a VRF system is achieved in this way, for example. At the same time a relatively high outside temperature can be applied in the air outlet. “We can now offer a highly efficient alternative to classic chiller / fan coil applications, in particular to companies and hotel chains, who do not want to install any direct expansion in their rooms,” Lechte explains the prospects for this. Two inverter controlled pumps are used in the HBC controller, which ensure that exactly the required amount of water is fed to the end units. “Water pumping stations, buffer tanks, anti-freeze and glycol are no longer an issue as a result,” says Lechte.

In addition, there is significantly less effort required in terms of planning and plant design, compared to a classic 4 pipe system. The basis for this is the energy shift within a building: whilst heat has to be drawn from one part of the building, another area needs heat. This can be shifted through the pipe network, thus making sensible use of it. In the process, the outdoor unit in this networked system differentiates between predominantly heating and cooling operation. Due to the energy shift and heat recovery of this technol-ogy, waste heat in summer for example can be used for hot water supply. Just as with standard VRF R2 systems, COPs up to 8 are possible.

“This technology was specifically developed for the needs of modern building architec-ture and maximum efficiency in using the available cooling energy and heat energy. Our aim is to highlight how comprehensive, highly efficient solutions based on renewable energy sources can be developed to fully supply buildings with heat and air conditioning using our products,” concludes Lechte.


Unpredictable weather conditions and pressure to conserve energy has made it mandatory for commercial property developments to consider installing air-conditioning systems that will save them energy and money, as well as provide hassle free maintenance service.

One of SA’s biggest banks appointed Mitsubishi Electric Air Conditioning (MSA) to install the City-Multi Variable Refrigerant Flow (VRF) air conditioning system in their lavish Cape Town premises, overlooking the ocean and mother city skyline.

The technical brief encompassed installing an air conditioning and energy sufficient system that would allow the building maximum heat recovery to reduce running costs as well as provide good quality air conditioning to Absa Wealth building occupants – its staff members and clients.

The main feature of the VRF heat recovery system is its energy saving capability - consuming less than 40% electricity than a usual constant volume air conditioner. Typically when an air conditioner is in the cooling mode, it absorbs the heat energy contained within the space it is trying to cool down, using the basic principles of refrigeration. Once this heat energy has been contained, it will reject the heat outside through an outdoor unit, making that heat redundant. The Mitsubishi VRF system however recycles that ‘redundant’ heat and uses it to heat or cool down other areas in the building, especially during winter months and or early morning and late afternoons, also heating water at 70 Degrees Celsius.

Roger Burrows from Mitsubishi Air Conditioning said: “As a leading manufacturer of energy efficient heat pump systems, we constantly strive to meet and exceed the increasing demands placed on our industry. The drive to reduce energy consumption and the impact its use has on the environment is crucial and increasingly important to us all. Sustainability has long driven Mitsubishi Electric to spend time and their resources researching and developing efficient air conditioning equipment, which meets our clients’ high quality standards. This fact, has led to successful installations at this highly prestigious building. ”

The ability for this system to heat, cool and heat water off one system simultaneously is unique to the air conditioning industry.

The list of contractors included Coastal Air Suppliers.
