Absorption Chiller "Energy-Saving Natural Chiller, Type PR Genelink"

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.

Heat Exchange Ventilation System Equipped with IAQ (Indoor Air Quality) Control

When there is only a small difference between the temperatures indoors and outdoors in spring or autumn, this Heat Exchange Ventilation System suppresses the power consumption by reducing the exhaust air flow rate, while keeping the same supply air flow rate. When the air temperature outdoors is lower than those of indoors and there is an increase in natural ventilation because of draughts and the like in winter, the ventilation system suppresses the power consumption by reducing the amount of ventilation (both the air supply and the exhaust).
The ventilation system efficiently controls switching between the two DC motors for the air supply and exhaust with a constant air flow control function, the heat exchange ventilation, and the normal ventilation, using the temperature sensors and humidity sensors. Accordingly, the optimal air flow and the ventilation method realize both comfort and energy-saving.

High insulation house panel: Technology Warm Panel

Technology Warm Panel (called Tekuno Atsutaka Panel) is a panel dedicated to technostructure for earthquake-resistant house building method. In the panel, insulating materials where bubbling gas with high insulation property is injected to the minute bubble structure with size just like a thickness of human hair (less than 100 micron) is used. By integrating the insulation materials and frame materials at factory, the panel has realized quality of applied high insulation. Moreover, a house with high insulation property has realized through energy efficient construction.
The technostructure is a method to build a wooden house with high earthquake resistant, using “Techno beam” which is a unique composite beam of laminated wood and iron plate, which was calculated with advanced structural calculation. With the method, providing a large space and cutting-edge exterior design, which was difficult to realize with conventional wooden-house building method, has become possible. By employing the technology panel on the wall of the house build with this technostructure method, and applying thermal insulation to other respective areas such as ceiling and floor, Net Zero Energy House (ZEH)*5 can be realized.

*5 Net Zero Energy House: a house whose annual primary energy consumption is zero (net) or almost zero, by improving energy-saving performance in terms of structure and facility of the house, utilizing renewable energy, and the like. ZEH is promoted under Japan's government initiative aiming at realizing ZEH for newly build house as standard by 2020.

Vacuum insulated glass, 'Glavenir'

Panasonic has manufactured and rolled out thin vacuum insulated glass with approx., 6mm thickness which is very thin. The glass featured with industry's top class insulation performance*6 , where the technologies that Panasonic has retained in the course of developing and manufacturing Plasma Display panels, are applied.
In addition to the float glass*7 specifications that have been rolled out so far, we have developed vacuum insulated glass using tempered glass specifications. The glass with approximately 8mm thickness, has realized 0.58W/m2・K, which is industry's top class thermal transmittance
In manufacturing process, vacuum insulated glass is welded with a sealing material that was made by melting two sheets of glass at a high temperature. In general, tempered glass loses its strength when heated at a high temperature. Therefore, we newly developed original 'Ultra-low temperature sealing material'. With the new sealing material, we have realized welding tempered glasses at a temperature range without reducing their strength. In addition, we have succeeded in putting the pillars that support the vacuum layer into practical use for transparent vacuum insulated glasses for the first time in the industry*8. As strong pressure is usually applied to the pillars, opaque material with high strength such as metal is used for the pillars. However, Panasonic has succeeded in developing a vacuum insulated glass with transparent pillars by developing a new 'transparent insulating material with high strength' for the pillars. With the glass where the new material is used for the pillars, users have a noiseless view with subdued presence of pillars more than ever before. Currently, multi-layered/triple glasses are often used for doors of refrigerator/freezer showcases. However, in pursuing to improve insulation property of the glasses with conventional technology, the door will be thicker and heavier. Therefore, 'Glavenir' will contribute to further improve its energy saving performance, solving such issue.

*6 Top class in the vacuum insulated glass market: 0.7 W/(m2・K)for the thermal transmittance of a single vacuum insulated glass with total thickness of approx.
6mm, as of December 12, 2019. This was investigated by Panasonic.

'AiSEG2', Core Component of 'HOME IoT'

Energy management product 'AiSEG2 ' is a core component of a 'HOME I' that connects various home appliances and housing equipment to the Internet for their operation. With the version up of 'AiSEG2' implemented in June 2019, the connection to operate a home solar power generation system in conjunction with an ordinary home Electric Vehicle (EV) charging equipment has been realized. AiSEG2's new function 'AI Solar Charge ®', which is combined with a photovoltaic power generation system, and equipped with AI (artificial intelligence), checks the weather forecast for the next day and uses the AI to identify the amount of surplus power based on the amount of power generated and used for the next day. If 'AiSEG2' identifies that there is surplus power for the next day, it orders to charge the home EV less at night, adjusting the charging amount based on the surplus amount, so that the electricity generated by the solar power generation system is used without energy loss.

Photovoltaic (PV) Module, 'HIT'

Panasonic HIT® Photovoltaic (PV) Module is featured with high energy conversion efficiency and excellent temperature characteristics by its unique heterozygous structure combining a single crystal silicon substrate with amorphous silicon layers. With the technology that reduces energy loss caused by reunification of positive and negative electric charges generated by sunlight, the 'HIT' minimizes loss of the energy generated by the PV cell and improves its power generation performance. The reduction ratio of the output amount of the energy is small when the temperature of 'HIT' panels become high during daytime, because the amount of power generated per effective area of a cell is large. Therefore, with 'HIT', larger amounts of power generation can be expected using the limited area of the cell panels.

For home use of 'HIT', by using the standard type with the half-type or trapezoidal type in a combination, it is possible to install larger capacity of 'HIT' cell panels even on a rooftop with complex shapes and/or small roofs. For public and industrial use, we also offer different types of 'HIT' to be suited to the needs for applications.

'HIT (Heterojunction with intrinsic thin layer)' is a registered trademark of the Panasonic Group.

"ENE-FARM" Household Fuel Cell

The ENE-FARM household fuel cell generates electricity through the chemical reaction between the oxygen in the atmosphere and the hydrogen it extracts from city gas (natural gas) or LP gas. The heat that is generated during that reaction can also be accumulated in a hot water storage tank and used in the household, so it is a system that has both high power generating efficiency and high energy-saving performance.
In April 2021, we launched new products as the seventh generation. On these new products, the LPWA (Low Power Wide Area) communications function*A is installed on all items as standard. Therefore, the ENE-FARM enables to receive weather information via the cloud. Once it receives a "power outage risk prediction", it automatically switches to the power generation mode in order to prepare for an outage. Even if a power outage occurs at a time when the operation of the ENE-FARM is stopped, such as during the night, it is not necessary to conduct a restart from an external power supply. It is therefore possible to use the electricity without any concern, even when a power outage occurs*B.
The ENE-FARM has also been equipped with a new function that uses an electric heater to heat the water if the gas supply stops. Furthermore, if the water supply stops, the ENE-FARM uses the hot water in the storage tank as domestic water*C. With these functions, one ENE-FARM unit facilitates ensuring the minimum infrastructure necessary during a disaster such as "power supply during a power outage", "hot water supply while the gas supply is stopped" and "domestic supply water during a water outage". Therefore, the value of the ENE-FARM as a resilience device has also been increased.

*A The network services using LPWA communications is available for ten years after starting the initial settings.
*B In order to perform power generation during a power outage, it is necessary that the city gas or LP gas and the water are being supplied. Also, this does not guarantee the generation of power during a power outage.
*C Please do not use the water for drinking.
