R-410A Inverter Unit Completes Daikin Mini Chiller Range


High efficiency solutions for residential and light commercial projects

The extension of the Daikin inverter driven mini chiller range signals the company’s ability to cover any cooling/heating requirement up to 14kW for the residential and light commercial market. Furthermore, the new EWAQ/EWYQ unit returns some of the best ESEERs (European Seasonal Energy Efficiency Ratios) and COPs in the industry today.

The mini chiller range is able to supply chilled water between 5 and 220 C and hot water at between 25 and 500 C at ambient temperatures of 10 to 450 C and -15 to 350 C respectively. Also, as well as delivering significant energy savings, it offers easy installation, compactness, quiet operation and the provision of constant room temperatures.

Enhanced energy efficiency

Underpinning Daikin’s concern for the environment, the mini chiller range is equipped with am inverter controlled scroll compressor offering maximum efficiencies, particularly in part load conditions. The 3 phase 9kW model for example, returns ESEER ratings up to 4.73 in cooling mode and COPs up to 3.48 in heating mode.

In addition to limiting stop/start cycles and thereby reducing energy consumption, the use of inverter technology ensures precise and stable water temperature control and higher comfort levels, as well as minimising peaks in power consumption, especially during start up.

Connectable to a wide range of indoor fan coil units, this extension to the Daikin mini chiller range gives the company a complete and highly competitive line of equipment that is ideal for installation in residential dwellings, large villas, guest houses, restaurants, small nursing homes, sports clubs and smaller residential outlets.

Additional benefits

An integrated hydronic kit, comprising circulating pump, expansion vessel, safety valves and a standard main switch, enable the mini chiller to become an easy to install ‘plug and play’ system. Other features include compactness (1420 x 1420 x 320mm), silent operation (64dBA sound power) plus multiple options such as evaporator heater tape and pump up to 90kPa available head. Daikin concern for the environment is reflected in a reduced refrigerant charge of less than 3kg.
