Sunfly “Smart Home Multi-Energy Complementary Management System”

The primary causes of global warming include rapid population growth, atmospheric pollution, marine ecological degradation, land destruction, and acid rain damage. These factors collectively lead to an increase in greenhouse gas concentrations, particularly carbon dioxide emissions, which exacerbate the greenhouse effect and cause a continuous rise in Earth's temperature. Thus, climate change is directly related to human activities, with carbon emissions from fossil fuel use being the main culprit.

According to a report from the International Energy Research Center, the construction industry contributes 40% of total global carbon emissions. Furthermore, the “China Building Energy Consumption Research Report (2020)” by the China Building Energy Conservation Association indicates that in 2018, the total carbon emissions from the entire building process accounted for 51.3% of the country's total carbon emissions. Currently, the Chinese government, committed to the ”3060 dual carbon strategy,” focuses more on reducing carbon emissions in industrial sectors such as electricity, steel, chemicals, and transportation, while there has been relatively little investment in reducing carbon emissions in the household sector.

SUNFLY GROUP, established in 1998 and headquartered in Europe, is a leading provider of intelligent living environment solutions in Europe. In 2010, SUNFLY established Hangzhou Sunfly Environmental Group Co., Ltd. in Hangzhou, China, serving as its trade and operations center in China. The brand is legally registered and protected under the agreements of the World Intellectual Property Organization in multiple countries and regions worldwide, including Germany, Hungary, Italy, Poland, and Russia.

SUNFLY is dedicated to the research, design, and production of HVAC equipment and accessories, with product sales spanning Europe and the Asia-Pacific region, and holds over 200 product patents. The group offers both residential and commercial products, including air source heat pump units, water system heat pump units, full air handling systems, ECU environmental control systems, SF fresh air purification systems, and SF intelligent control systems. Accessories include PERT, PEX-A, aluminum-plastic pipes and fittings, pure copper and stainless-steel manifolds and accessories, pressure-bearing manifolds, mixing systems, temperature control systems, and various valves, with thousands of products in total.

SUNFLY boasts a team of world-class industry expert consultants and R&D engineers. Emphasizing lean innovation as its research and development philosophy, SUNFLY upholds social responsibilities related to technology, green practices, health, energy conservation, and environmental protection. Recognizing the significant impact that reducing carbon emissions in the household sector can have on global carbon reduction efforts, SUNFLY has been consistently dedicated to this cause.

SUNFLY believes that future households will primarily have five demands:

1. Energy Efficiency and Carbon Reduction: This includes improving the insulation and airtightness of building enclosures to reduce energy demand, minimizing the use of fossil fuels, and increasing the utilization of clean renewable energy. To this end, SUNFLY installs solar photovoltaic power generation devices on rooftops and yards of residential buildings and integrates renewable energy through independent power storage/conversion devices.

2. Comfort and Health: Based on the theory of thermal comfort, SUNFLY effectively designs and manages various aspects of the home environment, including temperature, humidity, and indoor air quality. This is achieved through a combination of radiant and convective terminals, along with effective control of fresh air systems, to meet the functional requirements for a healthy and comfortable living indoor environment.

3. Safety and Stability: Generally, air-source heat pumps serve as the primary source for heating and cooling in a home environment, effectively meeting indoor climate needs. However, the efficiency of air-source heat pumps can be significantly affected by outdoor weather conditions. For example, during cold winter months, the efficiency and heating capacity of air-source heat pumps can decrease considerably, and unstable power conditions can also cause system failures. Therefore, SUNFLY recommends a combined operation strategy using air-source heat pumps and gas boilers. Gas boilers can effectively address the efficiency drop of air-source heat pumps in low temperatures and ensure a stable supply of hot water throughout the year. Moreover, based on energy prices (gas price/electricity price) and system efficiency (boiler efficiency/heat pump efficiency), SUNFLY has established a multi-energy complementary operation strategy. This strategy not only ensures the most economical operation of the home environment system but also guarantees its safety, stability, and reliability.

4. Integrated Operation: Whether it's the integration of renewable energy sources like solar photovoltaics + energy storage systems, the combined operation strategy of heat pumps + gas boilers, or the control of various environmental parameters indoors through different end devices, all require a centralized smart management system. This system includes data collection, protocol integration between different devices, local data transmission to cloud servers, data processing, comprehensive usage, and management by household users, among other functions and requirements. SUNFLY has developed a comprehensive “Smart Home Multi-Energy Complementary Management System” that encompasses all these functionalities. Through this system, various systems operate more efficiently, and the indoor applications for users become simpler.

5. Post-Sales Service: The more complex a system, the higher its post-sales service costs. Therefore, based on the foundation of the “Smart Home Multi-Energy Complementary Management System”, SUNFLY has additionally developed a digital function module for service processes. This module integrates and analyzes operational data, environmental data, and user usage data for various systems after effective authorization. When a system encounters faults or operates in a suboptimal condition, SUNFLY's intelligent operational backend can proactively identify issues and provide relevant troubleshooting recommendations to the respective home system installation service providers. This helps them resolve household user issues more efficiently, at lower costs, and in a timelier manner, thereby enhancing system reliability and service efficiency.

In summary, SUNFLY is not just a manufacturer of single HVAC transmission and distribution systems but also a solutions provider for home environment systems. Whether addressing energy-saving and carbon-reduction needs in the household sector or creating healthy and comfortable indoor environments, SUNFLY serves as a platform service provider based on digital intelligent operations. The company is dedicated to tirelessly working towards building future homes that are more energy-efficient, low-carbon, healthier, more comfortable, and smarter.
