Technology Overview

Inverter Technology

Environmental awareness continues to grow in developed countries, causing sales of energy-saving models to rapidly expand. Most notable is the growth seen in inverter type air conditioners, which lower energy consumption 30%, and heat pump heaters, which reduce CO2 emissions by 60% compared to fossil burning heaters using oil or gas.

With less than 37% diffusion rate for inverter type air conditioners in developed countries, demand for energy-saving products is expected to continue to grow.

Advantage of Inverter

  • Powerful Operation
  • High Energy Efficiency
  • Comfortable Cooling

Variable Refrigerant Volume (VRV)

When Daikin launched the VRV air conditioning system in 1982, it introduced the world’s first use of variable refrigerant flow control. This technology circulates only the minimum amount of refrigerant needed at any one time and enables individual climate control of air conditioning zones. The name VRV * derives from this technology that we call “variable refrigerant volume.”

VRV Advantage

  • Energy-Saving Operation
  • Individual Control
  • Adaptable Design
  • Flexible Layout

HFC32 – the next generation Refrigerant

In November 2012, Daikin became the first company in the world to use R32 (HFC). Used in residential air conditioners for the Japanese market, R32 has just one-third the global warming potential of conventional the R410A (HFC) refrigerant. In March 2013, we released a residential air conditioner using R32 in India. We aim to release these R32 air conditioners in other countries and use R32 for commercial air conditioners as well.

HFC32 Advantage

  • Contributes to Ozone depletion Potential Reduction
  • Contributes to Global Warming Potential Reduction
  • Environment Friendly
  • Less risk & better availability
  • Better costs
  • Better efficiency and less volume
