1, new fan:
The new fan is an effective air purification equipment, which can circulate indoor air. On the one hand, the indoor dirty air is discharged outside, on the other hand, the outdoor fresh air is input indoors through sterilization, disinfection, filtration and other measures, so that the indoor air is always fresh and clean.
The new fan adopts patented fresh air convection technology, which makes indoor air convection by independent air supply and air introduction, and realizes indoor air replacement to the maximum extent. The new fan has a built-in multifunctional purification system to ensure the indoor air is clean and healthy.
2. Blower:
The blower sends cold and hot air to the target through the air outlet side to achieve the purpose of air circulation or heating.
(1) The hot air required for combustion is sent to the furnace through the air preheater.
(2) The primary fan and air preheater provide hot air for drying and transport pulverized coal to the pulverizing system.
(3) The air delivered by the blower is heated by the outlet of the air preheater, and the hot air is sent to the furnace for the second time, so it is also called the secondary fan.
Extended data:
1, one-way fresh air system
One-way fresh air system is a "forced air exhaust and natural air supply" system. Install exhaust ports in kitchens, bathrooms and other places where dirty air gathers. The air outlet is directly connected with the shaft of the bathroom or the flue of the kitchen, and the air inlet for introducing fresh air is installed above the doors and windows of the bedroom and living room and directly connected with the outdoor.
When the system is running, the indoor air is continuously discharged out of the room through the air outlet, and negative pressure is generated indoors. Fresh air is filtered, dehumidified, deodorized and reduced in noise through the air inlet, and it is continuously replenished 24 hours a day.
2. Two-way fresh air system
Two-way fresh air system is an effective supplement to one-way fresh air system. In the design of two-way flow system, the positions of the exhaust main engine and the indoor exhaust outlet are basically consistent with the distribution of one-way flow, but the difference is that the fresh air in the two-way flow system is sent out by the fresh air main engine.
Through heat recovery, the temperature of fresh air sent into the room is close to the indoor temperature, which is more economical, energy-saving and environmentally friendly. Whether in hot or cold areas, the fresh air system can make the living room a soundproof, dust-free, clean, energy-saving and comfortable warm space.
