1. Comparison of heating principle
1. Tall space heating units
This unit is a energy -saving equipment specializing in tall space places such as factory buildings.When heating in winter, due to the heat and buoyant effect of air, a large amount of hot air will accumulate above the roof, which will form a large temperature difference above the roof and personnel activity area.The device is heated to the air, and then the air fabric is vertically blown out from top to bottom. After the hot air is forced to send the hot air to the working area, the air circulation rises again.Blow out, repeatedly carry out in this way to form a hot cycle.The temperature difference gradient is small and make full use of the top heat.
2, radiator
The radiator is to heat the surrounding air first, so that the air forms the convection in the room to achieve the purpose of heating.This heating method is that the temperature around the radiator is high. As the distance from the radiator increases, the temperature decreases, and the temperature difference at the same level is large, and the heat of the radiator is basically not felt 2 meters away from the radiator.Because this heating is a way to flow, the temperature of the room is cooling and cooling.The heating of high space, the heat air rises to the upper layer, so that the temperature difference between the upper layer and the ground to the ground will reach more than 10 degrees. The temperature in the area is severe, resulting in a large amount of energy loss.The air temperature distribution of the working area where people stay below 2M, and the area of ??the area away from the heating film is very low.
Second, heat source comparison
When the end is heated, a large amount of thermal air is accumulated above the ceiling, and the heat waste is about 40%to 50%.
3. Control system comparison
1. Tall space heating units
The control system of the high space heating unit can realize the single -scale single -control and centralized control of the equipment, flexible control, can be controlled in time and partition, and the operation is simple and convenient.Each device is configured with a control box, and there is a new R & D circuit board in the control box.Single and single -control: Each device can set the temperature independently, and set the air supply angle independently. The temperature control equipment can be started according to the temperature control equipment of the single device coverage area, and the temperature field is evenly distributed.Concentrated control: Each device can be connected to the centralized control touch screen through control lines to achieve wired control. Each device can also install a wireless launcher to perform wireless control.The entire system can be concentrated control and monitoring in the control room.A concentrated control touch screen can connect up to 31 devices.
The following functions can be implemented on the centralized control screen:
(1) Monitoring fan start and stop: You can manually start and stop fans, or you can automatically adjust the speed and start and stop fans according to the air return temperature.
(2) Monitor the opening of the air fabric delivery device: adjust the angle of the blade of the air outlet to the air outlet according to different air supply modes.
(3) Display air supply temperature and return air temperature.
(4) Show the water supply temperature and return water back temperature.
(5) Timing and shutdown: Set the shutdown time according to the working hours.
(6) Set temperature during the time period: You can set a working temperature (18 ° C) at the working hours; you can set a duty temperature of 5 ° C at non -working hours.

Flexible control can open the equipment according to the actual situation to achieve the purpose of energy saving.
2, radiator
There is no control system at the end. After the boiler is turned on, the hot water has been circulating, and it cannot be controlled according to the work area.
4. Comparison of occupation area
1. Tall space heating units
The tall space heating unit is lifted on the solid of the plant, and there is no need to occupy the floor space of the plant.
2, radiator
The radiator needs to be installed along the external wall inside the plant. It requires sufficient installation space to occupy the ground space. The space with a large span is difficult to arrange.
