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.

Residential fuel cell unit 'Ene Farm'

'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.

Vacuum insulated glass, Glavenir

Applying the development and manufacturing technology of plasma display panels, Panasonic Group has manufactured and rolled out vacuum insulated glass with a thickness of approximately 6 mm and the industry's top class insulation performance.*10 In addition to the previously developed float glass*11 specification, we have developed vacuum insulated glass using tempered glass specifications that is approximately 8 mm thick and offers the industry's top class thermal transmittance of 0.58 W/m2・K. Vacuum insulated glass is produced by welding two sheets of glass together with a sealing material that has been melted at a high temperature. In general, tempered glass loses its strength when heated at high temperatures. Our newly developed ultra-low temperature sealing material has allowed us to realize welding tempered glass at a temperature range that does not reduce its strength. In addition, as the pillars that support the vacuum layer are subject to extremely high pressure, generally high-strength materials such as metals are usually used. Panasonic has developed a high-strength insulating material to achieve vacuum insulated glass with high insulation. Glavenir received the Minister of Economy, Trade and Industry (METI) Award at the 2020 Energy Conservation Grand Prize in recognition of its technological development. We will contribute to the realization of a carbon neutral society on a global scale by introducing this glass into various industries where energy conservation is needed.

*10 In the vacuum insulated glass market. As of December 12, 2019, thermal transmittance of vacuum insulated glass with a total thickness of approximately 6 mm was measured to be 0.7 W/(m2・K) by our company.
*11 Glass widely used for window glass, etc.
