2019 China HVAC industry development summit held successfully
September 24-25, 2019 China HVAC industry development summit was held in Zijin villa, Nanjing. As the 16th professional grand meeting for HVAC industry, the theme of this summit is "intelligent manufacturing of cold and warm, fusion and new generation". It is not only a large-scale increase, but also the first industrial grand meeting to aggregate the entire HVAC industry chain and comprehensively upgrade. At the same time of deep link to authoritative resources, comprehensively control the general trend of the industry.
On the first day of the conference (September 24), the first air conditioning industry ecological forum was jointly held by industry online and Suning e-commerce. The theme of the forum was "whole chain driven green health and new ecology". The participants jointly discussed hot topics such as new energy efficiency standards and green health air conditioning development trend. At the meeting, the joint initiative of "green and healthy ecology of China's air conditioning industry" was jointly issued by China Academy of home appliances, China Refrigeration and air conditioning industry association, National Technical Committee for standardization of home appliances, sub Technical Committee of main parts for home appliances, Suning e-commerce, industry online, and air conditioning upstream and downstream enterprises, which is committed to industrial coordination, industrial ecology and ecological sharing Value. On the morning of the 25th, the theme summit of the conference was held. In the afternoon, there were two sub forums on air conditioning application and heating. In the evening, the grand Third China "intelligent manufacturing of cold and warm" award ceremony was held.
Analysis of novel coronavirus in office buildings
Novel coronavirus pneumonia cases were novel coronavirus cases in Wuhan in late 2019. As of February 11, 2020, nearly more than 50000 confirmed cases were confirmed by infection. The state called on us to do well in isolation and protection, away from crowded situations, but our home and office space were the necessary occasions for us to make use of it. Therefore, China Construction Association issued an urgent response to "new coronavirus" in office buildings. ”Guidelines for operation management and use of emergency measures.
It is recommended to use heat pipe heat exchange equipment (easy to reform + install fresh air ventilator)
"For the common forms of centralized heat recovery, I made the following comparison:
From the comparison in the figure above, we can see why the Construction Association recommended the heat pipe heat exchanger to supplement the fresh air. Under the current situation, the heat pipe can effectively avoid cross infection of air while supplementing the fresh air and recovery energy. Moreover, the heat pipe has other natural advantages. Take Shanghai xinhaojia 3D heat pipe as an example:
On the basis of the heat pipe, the heat pipe type fresh air ventilator has a variety of functions to choose in addition to its unique characteristics.
(transformation + non-standard customization of new projects)
The whole air system proposes to increase the fresh air and exhaust air, and close the return air system. If there is no reasonable heat recovery device, it will cause huge energy consumption. It is recommended to install heat recovery heat pipe, with the following characteristics:
The whole air system proposes to increase the fresh air and exhaust air, and close the return air system. If there is no reasonable heat recovery device, it will cause huge energy consumption. It is recommended to install heat recovery heat pipe, with the following characteristics:
Therefore, no matter "hot and cold end + fresh air" or "all air system", through continuous indoor and outdoor air exchange, the harmful gas produced will be discharged out of the room, so that the concentration of indoor harmful gas is far lower than the level that can harm human health. The main unit of the heat pipe type fresh air system with heat recovery function is equipped with a sensible heat recovery system. When the air in and out passes through the heat exchanger, the energy exchange of preheating and precooling is carried out, which can retain 65% of the energy of indoor air, avoid energy loss, reduce the loss of cooling and heating, save energy, and effectively isolate cross infection. The ordinary air exchange equipment can directly indoor When the air is discharged out of the room, it will lead to the loss of cold or heat of the indoor air, resulting in the waste of energy, which is not conducive to energy conservation.
