Products that contribute to CO₂ reduction

The Aeolia X series of room air conditioners offer both comfort and energy efficiency throughout the year, as interest in energy conservation continues to grow due to the recent rise in electricity prices. The need for energy conservation in air conditioners is growing due to the recent rise in prices and the rise in electricity prices, while the number of people who leave air conditioners on for long periods of time is increasing due to the intense summer heat. Focusing on the fact that many air conditioners are operated with less power after reaching the set temperature, this product is equipped with a newly developed "Eco Rotary Compressor" (installed in 200 V models except for 9.0 kW class models) with a newly developed compressor structure to achieve a minimum output of 0.3 kW during cooling operation. By lowering the minimum output, it is possible to reduce the frequency of turning on and off when the room temperature is stabilized after reaching the set temperature, thereby maintaining a comfortable room temperature and humidity while reducing power consumption.

The GHP (Gas Heat Pump air conditioner) is an air conditioning system that drives the compressor in the outdoor unit with a gas engine and uses a heat pump to perform the heating and cooling.
The "XAIR III" ultra-high efficiency GHP launched in 2020 has a reduced machine size and maintenance space and its installation space was reduced by 17% from that for conventional models. In addition, thanks to technical development such as improvements to the freezing cycle efficiency and blower efficiency, approximately 10% reduction of the annual energy consumption of the GHP have been realized compared with the previous series, which indicates that the GHP has simultaneously realized both smaller size and more energy saving.
These aspects have been evaluated very highly and the GHP has received many awards, including the Energy Conservation Grand Prize 2020 (Director-General of the Agency for Natural Resources and Energy Award).

Panasonic will contribute to the realization of carbon neutrality by promoting self-consumption of renewable energy with the Ohisama Eco Cute.

An absorption chiller is an air conditioning system that uses the heat of vaporization of refrigerant under vacuum, without using a compressor. The chiller uses water as the refrigerant and thermal energy as the operational power source such as the waste heat from factories and the combustion heat of gas. Therefore, the chiller is suitable for air conditioning for large-scale facilities such as domed stadiums, as air conditioning equipment that is environmentally friendly because of low power consumption. The system has large advantages that it is possible to lower the electric power load peak when the cooling load is high, that it uses water as a natural refrigerant, and that the outdoor unit installation space required is smaller than the one required for other air conditioning facilities of a similar capacity.
Compared with conventional products, this chiller reduces the rated cooling water flow rate by 30% and the cooling water pump conveyance power by 65.7%. This reduces the electric power consumed by the cooling water pump, which is a unit that consumes a large amount of power, minimizing it as far as possible. Furthermore, the 23.5% reduction of gas combustion through the utilization of waste heat indicates that energy-saving has been realized. These reduction were favorably evaluated for the product as a whole and it received the Promotion Award of the Heat Pump & Thermal Storage Technology Center of Japan in the 2017 Demand-Side Management Awards.

'Ene Farm' residential fuel cell unit is a system that provides high efficiency for power generation and energy saving benefits. 'Ene Farm' extracts hydrogen from city gas (natural gas) or LP gas, and then chemically reacts the extracted hydrogen with oxygen in the air to generate electricity. The heat generated by the reaction is stored in a hot water storage tank and can be used at home.
All of 'Ene Farm' units are equipped with the LPWA (Low Power Wide Area) communication function as standard that enables receiving weather information through cloud. In the case that 'Power Outage Risk Prediction' is received, its power generation mode is automatically switched to be prepared for power failure. Even in the event of a power failure at midnight or other times when the 'Ene Farm' has stopped generating electricity, there is no need to restart the 'Ene Farm' with an external power source. Therefore, 'Ene Farm' users can use electricity without worrying even in the event of a power failure.
In addition, for the case that the gas supply is stopped, a new function is equipped to boil water using its electric heater. Moreover, when the water supply is cut off, the hot water in its hot water storage tank can be used as domestic water. Thanks to these features, with one 'Ene farm' unit, it facilitates securing the minimum necessary infrastructure in the event of a disaster, such as 'electricity in the event of a power outage', 'hot water in the event of a gas supply stop', and 'domestic water in the event of a water outage'. Therefore, 'Ene Farm' users can spend time at home without worrying even when they are forced to sheltered at home.

'Emanage' is a cloud-type service that provides continuous support for energy-saving activities at facilities, from detection of a problem to operation and improvement of the facility. As for visualization, based on the measurement results of the power consumption by circuit breaker, transition of the measurement results such as gas can be displayed by year, month, week, day (1 hour) , and day (30 minutes) on the monitor. Moreover, based on the measurement results of power consumption by system, details of the power consumption by electric light and power systems can be checked in stacked bar graphs on the monitor. 'Emanage' clarifies when, where, for what, and how much electricity is used, and then, improves operations such as demand control of lighting equipment and air conditioners in response to the detected problem, which contributes to reducing energy consumption of the customer.

The pure hydrogen fuel cells are based on technologies developed in the home fuel cell EneFarm. For example, by sharing the fuel cell stack, a key device, with EneFarm, we achieved stable power generation performance and 56%*¹⁰ power generation efficiency, the highest level in the industry*⁹. Since this product is targeted for business use, the power generation output has been enhanced to 9.9 kW, more than 14 times the power generation output of the home EneFarm (700 W). Furthermore, by connecting and controlling multiple units, the power generation output can be scaled out according to demand, and by taking advantage of its lightweight and compact chassis size, it can be flexibly adapted to various installation conditions, such as on the roof of buildings or in small areas.
In fiscal 2022, our company HX KUSATSU, a demonstration facility that uses 100% renewable energy*¹¹ for all power consumption in the manufacturing division of the fuel cell plant located at the plant in Kusatsu, Shiga Prefecture, Panasonic, was put into operation using a combination of pure hydrogen fuel cells and solar cells. By visiting this facility, you can feel closer to the CO₂ reduction solution using hydrogen.
