ECOLUTION KX4 high efficiency VRF air conditioning systems
July 04th 2007

ECOLUTION KX4, the VRF multi air conditioning system from MHI has now been further enhanced with new models that deliver increases in energy efficiency of up to 13% from previous models.

The new systems are available in 8hp (22.5kW), 10hp (28.0kW) and 12hp (33.5kW) cooling capacities as both 2-pipe heat pump systems and 3-pipe heat recovery, with CoP levels of up to 4.24 (8hp model). This means 4.0kW of heating can be delivered in to the conditioned space from just 1.0kW of power input.

With the innovation of R410a refrigerant and inverter logic control technology,MHI are able to offer some of the most energy efficient air conditioning systems available and now efficiency has been further enhanced by the development of MHI’s compressor technology with a new design coil within the compressor that reduces the operating current and reduces the power consumption of the outdoor units by up to 10%, meanwhile modifications to the refrigerant circuit and other key components, such as DC fan motors, have increased efficiency further.

Mr H.Yamada,Technical Manager of MHI Europe explained: “we are constantly striving to achieve the highest possible levels of energy efficiency on our core products, investing in the research and development of our compressor technology is vital to this, combined with an intelligent approach to the design of other key components such as fans and heat exchangers we are able to achieve industry leading levels of efficiency”.

In an increasingly regulated environment where there is such a clear demand to reduce power consumption in buildings and plant equipment, Mitsubishi Heavy Industries has the ability to optimize efficiency throughout the product range to meet these demands. Energy efficiency is combined with unrivalled levels of control and reliability, making the ECOLUTION KX4 systems the right solution for comfort cooling applications of any size, from small open plan areas to multi storey buildings.
