At present, a kind of negative pressure operating, low intensity infrared radiation heating system - gas infrared soft intensity radiation heating system is widely used in heating of large space buildings in foreign countries. There are also many large building heating projects used in our country.


	 


	Gas infrared radiation heating uses radiation as the heat transfer mode, natural gas, liquefied petroleum gas as the heat source.Since air is a material that radiates through heat, radiant heat is essentially neither absorbed nor reflected in air.When the strong infrared ray (wavelength 2.5-1 000μm) of the radiation system touches the ground, people and objects, the energy emitted is absorbed by the surface of the object, and makes it hot.Secondary radiation from the heated surface through these objects increases the temperature of the nearby air, thereby releasing heat into the working space.

	Gas radiant heating is driven by a negative pressure centrifugal fan, so that the hot fluid flows in the radiation pipeline of the system, and the tail gas is discharged to the outdoor.In the heating space, the system hangs the radiation pipeline on the ceiling or under the roof grid frame, and the reflection panel above the radiation pipeline radiates heat to the space below.


	 


	Gas infrared radiation heating has high radiation intensity and good effect.In the environment of radiation heating, the envelope structure, the ground and the surface of the equipment in the environment have a higher temperature. The dual effect of radiation intensity and temperature creates a thermal state that truly meets the requirements of human heat dissipation, so the human body has the best comfort. At this time, the realistic temperature of human body is higher than the ambient air temperature.At the same time, as the temperature of indoor surface is raised, the cold radiation of surrounding surface to human body is reduced.


	 


	During the heating period, the surrounding envelope structure, the ground and indoor equipment all absorb radiation heat, and store some heat. When the radiation heating stops, the accumulated heat begins to dissipate to the environment, so a certain thermal environment can be maintained.So radiation heating starts up very quickly and cooling is slow.

	Gas infrared radiation heating equipment adopts negative pressure operation technology. Before the system ignition, the vacuum pump starts to work. When the controller confirms that the negative pressure is normal, the ignition test is carried out.When any link of the system (power supply, gas supply, negative pressure, ignition) fails, the system will automatically shut down.Fully ensure the safety of equipment and heating area.


	 


	Each set of temperature control system includes a black ball temperature sensor and a controller.The black ball temperature sensor is installed in a representative position in the control area. The controller compares the temperature signal from the sensor to generate control instructions, and adjusts the control temperature by turning the control device on or off.The control area can be freely defined according to the user's requirements.In different control areas, users can set different indoor temperatures according to needs.The controller can set the temperature of different periods of 24 hours according to the needs of users, and can set the on-duty heating temperature of 5℃. There is no need to design special on-duty heating.It can also set the working state of the equipment on different days within a week according to the needs of users, such as the opening time, the temperature of different periods, etc.


	 


	The traditional radiator heating can only run in the heating period, once the heating is stopped, the pipeline and equipment in the water heating system may be frozen and cracked.Radiant heating systems can start and stop as needed.


	 


	Gas infrared radiation heating system is a new type of heating system with high efficiency and low operating cost, and the energy cost saving is far more than the traditional method.Gas infrared radiation heating is used in tall space buildings, such as workshops, warehouses, stadiums, garages, hangars, aircraft maintenance warehouses, shipyards and other occasions is practical.
