The spread situation and the future view of the CO2 refrigerant heat pump water heater in Japan.
Author(s) : KUSAKARI K.
Summary
In January 2001, for the first time in the world, Tokyo Electric Power Co., DENSO CORP., and Central Research Institute of Electric Power Industry have reported the practical application of the CO2 refrigerant heat pump water heater for residential use, which can save more than 30% of energy compared to conventional combustion type water heater. The government has started a subsidy system in September of 2002, and at the end of March, 2006, about 480,000 of the system have accumulatively forwarded to the whole market and now it continues to spread around well. This paper deals with the development background of CO2 refrigerant heat pump water heater "Eco Cute" in Japan, its widespread use situations, performance improvements achieved since introduction of the first model, variations, user evaluations, efforts by Tokyo Electric Power Company, programs for supporting the widespread use, challenging issues and future prospects.
