Operation ON/OFF unit. Partial load condition - ON/OFF. This chart chows a blue line going up and down between 4 and -4 degrees.

In this typical application, when full capacity is not required, the compressor works in partial load operation. Traditional on/off ground -source heat pumps alternately switch ON and OFF and the brine temperature decreases down to -4°C.

Operation Daikin unit. Partial load condition - inverter controlled. This chart shows a steady line just above 0 degrees.

Daikin's inverter technology produces a stable outgoing brine temperature of around 0°C. This higher and more constant evaporating temperature leads to greater operating effinciecies.

Seasonal efficiency, smart use of energy

Customers are looking for the best solutions for their home, with an eye on the energy efficiency labels. Daikin always proposes the most environment friendly units with the maximum energy labels for the eat pumps. Since the 26th of September 2019, new energy labels are available and rate the heating products from A+++ to D in space heating, and from A+ to F in water heating.
