With the rapid development of China's economy in the new era, people's requirements for building functions have gradually changed from the original emphasis on economic applicability to the pursuit of quality. There are more and more tall space buildings, which give people a feeling of ease and ease and atmosphere. At the same time, the popularity of tall space has put forward higher requirements for the professional design and installation of HVAC.Designers should provide HVAC design scheme suitable for the building itself according to the different characteristics of the project.


	 


	Tall buildings are mainly used in civil public buildings and industrial buildings, among which civil buildings are mainly commercial buildings, cinemas, stadiums, concert halls and exhibition halls, and industrial buildings are mainly determined by industrial technology height.The function of tall space is often more complex for HVAC professional, the main concern is the thermal load characteristics of tall space buildings.

	Hot water radiant panel is a kind of heating equipment installed in the indoor ceiling of a building by means of infrared radiation heat transfer. Its essence is thermal radiation technology.Hot water radiant panel is a heating system that takes the metal radiant panel combined with tube and plate as the radiant source, takes ordinary hot water and high temperature hot water as the medium, arranges the radiant panel in series type strip, and is installed in the form of ceiling. This system is superior to the traditional convective heating and hot air heating equipment, and solves the problems of poor effect and high energy consumption of convective heating in tall space.It is a new heating technology for tall space buildings.


	 


	Tall space hot water radiation plate can be applied to industrial plants, locomotive maintenance factory, logistics warehouse, sports venues, exhibition halls, auto 4S shops, large business super and other tall space places, the system solves the heating needs of tall space, suitable for 5 meters above 30 meters below the tall building place, is a mature technology, simple installation, flexible control of heating and cooling system solutions.


	 


	1. Save energy 


	Infrared radiation heating, no convection phenomenon, small thermal inertia, no need for a long time to preheat, heating speed.In tall Spaces, reducing vertical gradient heat loss means saving energy and money.


	 


	2. Static heating 


	No fan operation, no noise, no air disturbance, quiet operation, avoid air convection ash phenomenon.Even in smoky places, workers feel warm and comfortable.


	 


	3. No fire risk 


	No electrical equipment, no flammable parts, hot water as a heat transfer medium, do not increase the building fire rating.Can be used in volatile and flammable building environment, without the risk of fire and explosion.


	 


	4. Convenient operation and maintenance 


	The system does not require any special maintenance and has no moving mechanical parts.There is no need to set up a special post to manage and maintain.


	 


	5. long service life 


	Hot water radiant panel has long service life and low maintenance cost.No special maintenance is required, except for the boiler and circulating water pump, which require regular maintenance, but are trivial compared to their energy-saving features.

	Example of hot water infrared radiation heating technology application -- Swimming pool and Tennis hall project in Ulanqab City 


	 


	Project location: Ulanqab, Inner Mongolia 


	 


	Project Overview:Ulanqab natatorium, tennis stadium project is the main project of the city to bid for the "14th Movement" of the autonomous region, located in Jining New District, covers an area of 101,200 square meters, construction area of 25100 square meters, the total height of the building is about 20 meters, the plane is "bow" shape, on both sides of the wider part of about 80 meters, the middle of the narrower part of about 40 meters, the total length of the building is about 270 meters.The natatorium is a Class B sports building with a total seating capacity of 1018. It can hold various individual competitions and water polo training.The Tennis Hall is a Class C sports building with a total seating capacity of 481. It can hold local and mass sports meetings and meet the requirements of tennis, badminton, table tennis and other sports events.(Excerpt from: Ulanqab City People's Government website, "Ulanqab Natatorium Tennis Hall Construction Starts")


	 


	Equipment usage: The project selected ECOPAN infrared hot water radiation panel to assume the heating function, simple and beautiful product style and modern sports facilities match, reflecting the ideal combination of practicality and aesthetics.,


	 


	The hot water radiant panel adopts an innovative design concept. The pipe, as the warmest part of the panel, is completely downward, and 70% of its surface is wrapped by a metal plate (covering an Angle of more than 280°), which increases the heat transfer area and ensures excellent heat transfer from the tube to the plate.
