Against the backdrop of today's global warming and increasingly stringent energy efficiency requirements, the HVAC industry is facing unprecedented challenges and opportunities. As a global provider of sustainable environment optimization solutions, Copeland is once again leading the industry to new milestones with its innovative spirit and technological prowess.

In March 2024, Copeland announced the launch of its newly developed 50HP Large Scroll compressor solution, filling the gap of the industry's large horsepower scroll compressor. The solution innovatively realizes cold capacity enhancement and can replace the application of small-cooling capacity screw compressors, which will help users in air conditioning, heating and other fields to realize the double benefit of corporate value and social value, and promote the industry to high efficiency, low carbon and green development. The debut of this new product not only marks a new level of technological progress for Copeland compressors, but also brings the industry a new option to realize the goal of environmental sustainability.

In China's public buildings, the energy consumption of refrigeration plant rooms occupies the vast majority of the energy consumption of air conditioning and ventilation systems, with its energy consumption accounting for about 70%. Seven ministries and commissions, including the National Development and Reform Commission, the Ministry of Housing and Urban-Rural Development, and the Ministry of Finance, jointly issued the Green and Efficient Refrigeration Action Program on June 13, 2019, which explicitly requires that by 2030, the energy efficiency of refrigeration in large-scale public buildings will be improved by 30%, the overall level of energy efficiency in refrigeration will be improved by more than 25%, the market share of green and efficient refrigeration products will be increased by more than 40%, and an annual power saving of 400 billion In October 2021, in order to realize the "double carbon" goal, China has successively issued relevant working opinions and action programs on carbon peak and carbon neutrality, and clearly defined the development goal of energy transformation. Therefore, the efficient design of refrigeration plant rooms not only meets China's national conditions and policies, but also reduces energy consumption and promotes the high-quality development of related industries and green low-carbon transformation.

Recently home renovation, 3 rooms, 2 halls. 110M2 or so (excluding the evil common share) If you want to get a cabinet unit, it takes up space, not to mention. At least 4 cabinets. The installation is too troublesome. The line is also more ugly.
Before considering the home central air conditioning. Then I heard the designer say that there are also air duct units.
The designer said that central air conditioning is more expensive than ducted units. And the effect is the same. And the central air conditioning requirements for the ceiling is higher than the air duct. It will sacrifice the floor height.
I checked before and no one came to ask about the difference between the 2. But there is talk of ducted units being a type of central air conditioning as well.

In recent years, with the social and economic development, on the one hand, people have higher and higher requirements for living environment, and the five permanent residences with the characteristics of constant temperature, constant humidity, constant oxygen, constant cleanliness and constant staticness can satisfy people's demands for a good living environment; on the other hand, how to make the five permanent residences air conditioning system energy-saving and emission reduction, and how to reduce the carbon emission of the whole life cycle has become a big challenge. Wuhang residence adopts capillary radiation + fresh air dehumidification air conditioning system, capillary cooling and heating source usually adopts ground source heat pump, the system has high efficiency and low carbon and environmental protection, and the fresh air treatment needs high grade cold source, so how to improve the efficiency of the fresh air treatment, reduce the energy consumption of the fresh air treatment, and make the system economic and reasonable, energy-saving and high efficiency, low carbon and environmental protection become the key of the air conditioning system.

On March 14, China Appliance & Electronics World Expo 2024 (AWE 2024) is held in Shanghai New International Expo Center. Under the theme of “Gree, Creating a Better Life”. Gree built three better life experience zones of “Comfortable Life”, “Healthy Life” and “Convenient Life” and held diversified brand activities on site, including Strategy Launch Conference, Food Tasting: Gree Kitchen Appliances for Easy Cooking, Intelligent Home Appliances Promotion and so on, delivering the brand concept of “Gree, Creating a Better Life”.
