Hitachi’s new line of mini-split systems feature vector DC inverters to achieve high performance energy efficiency, the company notes. These inverters cool with maximum capacity at start-up, then automatically slow down and operate at minimum capacity to maintain room temperature at a comfortable level. This reduces energy consumption by up to 62%* compared to non-inverter levels. A special microchip that is pre-loaded with the compressor’s data will constantly monitor its operation while running. This helps the unit to adjust the amount of energy needed by sending accurate instructions to the compressor to achieve the optimal rotation speed and avoid unnecessary power waste, Hitachi adds.
