Mitsubishi Electric has launched a range of advanced, inverter-driven chillers to the UK market to challenge the traditional way of delivering cooling and heating.
The highly efficient e-series modular chiller range is designed to answer the need for controllable, energy efficient cooling and heating with reduced plant size and a host of advanced features and benefits taken straight from the company’s experience in the air conditioning industry.
“Our engineers have examined every single component to find ways of increasing performance, reliability and overall system efficiency”, explains Jason Tinsley, Product Manager, Central Plant.
The e-series uses two advanced DC inverter-driven scroll compressors in each 90kW module – taken from the VRF (Variable Refrigerant Flow) sector, to deliver a capacity range of 8% to 100%. The models deliver market-leading levels of efficiency with the ability for units to operate on their own or in tandem with others.
The unique shape and modular design of the e-series means that the system can be constructed with up to six individual units connected together, to provide capacity of between 90kW and 540kW.
The modular approach also enables the company to hold units in stock available for on-site delivery, rather than clients having to build to order.
“Chiller systems have been used for decades to deliver controlled cooling to buildings, but with increasing pressure of energy efficiency and running costs, we now need a low-carbon, cost effective alternative”, adds Tinsley.
The e-series achieves some of the quietest noise level on the market which is increasingly important in inner city locations. These low noise levels are achieved through both the unique construction and design of each unit as well as the advanced component technology within each chiller, which is also easily integrated within new and existing systems using BEMS control.
“We are bringing these to the UK chiller market because we believe the time is right for a high performing, low carbon solution that can also help reduce space requirements”, says Tinsley.
· High efficiency inverter compressors. Two advanced DC inverter-driven scroll compressors are incorporated within each 90kW module. This gives a capacity range of 8% to 100% for each module.
Two-stage cooling circuit. Both compressors serve separate plate heat exchangers located in the centre of the unit. By modulating the evaporating temperature individually, overall system efficiency can increase by an additional 3.9%, compared to single evaporating refrigeration cycles.
