On the morning of June 24, 2024, a major fire accident occurred in the factory of South Korean lithium battery manufacturer Aricell located in Hwaseong City, Gyeonggi Province, the place where the fire started was the lithium battery finished product inspection and packaging workshop, and the monitoring screen showed that initially, a small stream of white smoke came out from the battery, and then the fire started rapidly, and it took only 15 seconds for the fire to cover the entire workshop space. According to the Korean media, this may become South Korea's "history of the most serious" chemical plant accident.

Recently, the industry's first white paper on low-carbon intelligent buildings, "White Paper on the Development of Low-Carbon Intelligent Building Technology Innovation and Development 2024 (Operation and Management)", edited by the Low-Carbon Intelligent Building Industry Technology Innovation Strategy Alliance, was officially released.

Life is a journey of chasing dreams, and role models are the bright lights in the journey, illuminating the road ahead and giving the strength to move forward. HVAC magazine adhering to the "focus on youth role models, carry forward the spirit of youth" of the original intention to open the "To Youth" column. In this issue, we invite the young design master (full name is "2023 First China Pharmaceutical Engineering Design Association China Pharmaceutical Engineering Design Master") - Liang Lei, to share with you the work experience and the message to the young engineers.

The air conditioner lack of fluorine air conditioner does not cool a common reason is the lack of fluorine, if you find yourself home air conditioning cooling effect is not as good as before most likely because of the refrigerant is not enough or leaking.

The main components of the central air conditioning and energy saving points
The energy saving of air conditioning project mainly includes: saving electricity, saving water, saving cold and heat.
The energy consumption of air conditioning and refrigeration system has accounted for more than half of the energy consumption of air conditioning project according to the assessment, the central air conditioning system has a host and the end of the system.
According to the burden of indoor heat and humidity load of the medium used can be divided into all-air system, all-water system, air-water system, refrigerant system.
According to the degree of concentration of air handling equipment can be divided into centralized and semi-centralized.
According to the source of the treated air can be divided into closed, DC, mixed (primary return air secondary return air).

As the era of carbon neutrality approaches, the booming development of the green economy and the strengthening of the trend of competition among related industries in the context of the transmutation of the global energy structure have ushered in a new wave of transformation and upgrading in all industries, and the heating and cooling industry is no exception.
