Compilation unit of National Building Standard Design Atlas

The company has been committed to the research and development of high-rise space heating equipment. In order to break the temperature gradient of high-rise space heating, the company has conducted in-depth cooperation with China Aviation Design Institute, Jilin Provincial Architectural Design Institute, Jilin Provincial Architectural Engineering Research Institute and other scientific research institutes in product research and development. A "Master Studio" composed of national HVAC masters Luo Jijie, Xiao Wu, Chu Yi and other experts has been established to provide technical support for product development. The company has successfully manufactured high-space heating (air conditioning) equipment with full intellectual property rights and patents, and participated in the preparation of the "High-space heating (air conditioning) equipment selection and installation-lateral air supply type" national building standard design atlas has been officially released in November 2019.

Jinghan Heating Classroom -1 Heating Temperature Gradient

Heating temperature gradient: the building in the heating process, there is a building with the height of each meter, the indoor temperature rise 0.3-1.5 ℃ change rate. This heating temperature change, as the heating heat medium temperature increases, the rate of change of indoor temperature rise will change more, this phenomenon is called heating temperature gradient.

Jinghan Heating Classroom -2 Chimney Effect

Chimney effect: refers to the indoor air along the vertical slope of the space to rise or fall, resulting in the strengthening of air convection phenomenon. It will cause the accelerated flow of indoor air, accelerate the heat flow upward, to the outside of the building loss.

Causes and Results of "Heating Temperature Gradient" in Jinghan Heating Classroom -3

The temperature gradient phenomenon is due to the indoor air in the radiator heating process, the air molecules have thermal energy, the relative density becomes smaller, the unit volume mass becomes lighter, by the buoyancy of the surrounding cold air upward flow generated "hot air upward flow phenomenon". It will cause heating problems such as high ceiling temperature and low ground temperature in the heating room, and the heating cannot meet the requirements. The radiator heat dissipation method is the natural convection air heating equipment. When the radiator works, more than 60% of the heat is generated by air convection, which is the main reason for the "temperature gradient. Another 35% or so of the heat is
