  • 4, What is the difference between the exhaust system and the smoke exhaust system?
  • 5, How does the exhaust system calculate the exhaust air volume?

The difference between ventilation system, air supply system and smoke exhaust system

1. The smoke exhaust fan needs to be high temperature resistant, and the wind speed in the pipe should also be higher than that of the air supply and exhaust system. Moreover, the valves of its air ducts are also different.

2. The difference between ventilation system, air delivery system and smoke exhaust system: the ventilation system includes air delivery system, exhaust system and smoke prevention system. According to the literal meaning, we can understand what they are for.In general, it is constructed separately; for example, separate air delivery system and exhaust air system.

3. The ventilation system includes: air delivery system, exhaust air system, smoke prevention system. According to the literal meaning, we can understand what they are for. In general, it is constructed separately, such as a separate air delivery system and exhaust air system.

What are the types of fresh air systems? What are the types of fresh air systems?

Pipe fresh air system: install exhaust fans and exhaust pipes and other supporting facilities in the kitchen and bathroom, and install air inlets in the bedroom and living room. When the exhaust fan is running, the original air in the room is discharged, so that the indoor air generates negative pressure, and the outdoor fresh air enters the room.

What does the fresh air system refer to? The fresh air system is an independent air treatment system composed of an air supply system and an exhaust air system. It is divided into two types: a pipe-type fresh air system and a pipeless fresh air system.

Full heat exchange central fresh air system. The outdoor fresh air is first filtered, enters the full heat exchanger, and then sent to various areas through the air duct and air inlet; the indoor turbid air passes through the indoor exhaust port, enters the full heat exchanger after being filtered, and then discharged to the outdoors.

There are three mainstream fresh air systems now: one-way flow fresh air system, two-way flow fresh air system and full heat exchange fresh air system. The adaptation scenarios of these three fresh air systems are very different. Each type has its own advantages and disadvantages. Consumers should choose according to family conditions.

The fresh air system is a set of independent and perfect air treatment system composed of the air delivery system and the exhaust air system.

Is it better to use exhaust air or a fresh air system for the private room of the chess and card room

The noise of the fresh air system is low, the international noise standard is 40 decibels, and the European and American standard is 30 decibels. The standard space fresh air system is only 26 decibels, and the master bedroom, the elderly room and the baby room can enjoy a quiet sleep at night. The standard space fresh air system has exhaust air and inlet air, and fresh air can enter every corner of the room.

The fresh air system is designed to change air in a space once an hour. Such a reasonable design completely solves the problems caused by the exhaust fan. The fresh air system works 24 hours a day, 365 days a year, so it can ensure air circulation at all times.

Installation of exhaust equipment: Installing exhaust equipment in the chess and card room can exhaust the indoor air outdoors, thus reducing the degree of indoor air pollution. The installation of exhaust equipment needs to be designed according to the actual situation of the chess and card room to ensure that it can effectively discharge harmful gases outdoors.

It is necessary to install a new fan in the chess and card room. After all, the air does not circulate much. Ours is made of Holy Island, which is of good quality and very cost-effective.

What is the difference between the exhaust system and the smoke exhaust system?

The exhaust system and the smoke exhaust system in the fire protection system are two different systems, but they play a complementary role in fire safety. Exhaust system refers to a system that discharges indoor smoke, harmful gases, heat, etc. outdoors through mechanical equipment.

The smoke exhaust system and the ventilation system are two different systems, and they play different roles in buildings. The following are their differences: Function: The main function of the smoke exhaust system is to exclude harmful substances such as smoke, toxic gases and heat to ensure the safety of personnel and the integrity of buildings.

In addition, the fans required by these systems and the wind speed in the pipe are also different. The exhaust fan needs to be resistant to high temperatures, and the wind speed in the pipe should also be higher than that of the exhaust system.

Ventilation pipes have different functions. Pipeline equipment that can promote air circulation and reduce the content of harmful gases. The exhaust pipe collects harmful objects from the exhaust fan or air intake, sends it to the purification equipment through the pipe, and discharges it or reuses it after meeting the standard. For different uses, ventilation ducts can be used in industry, construction engineering and urban infrastructure.

How does the exhaust system calculate the exhaust air volume?

Exhaust air volume L is calculated according to the following formula: L = L1+ν·F·β. In the formula L1 - the amount of pollution gas in the cabinet, /s; the confirmation of this direction needs to pay attention to the use environment, and see which part is the most suitable for installation, so that the exhaust fan can achieve the best use effect.

The definition of fan air volume is: the product of wind speed V and air duct cross-section F.Because large fans can accurately measure wind speed with an anemometer, the air volume calculation is also very simple. The air volume can be calculated directly by using the formula Q=VF. Determination of the number of fans Calculate the total air volume required by the factory according to the number of ventilations in the selected room, and then calculate the number of fans.

Calculate the air volume, wind speed and pipe diameter of the exhaust fan outlet: pipe diameter D (m); wind speed U (m/s); air volume Q (m3/h); S cross-sectional area (m). L pipe length (m) D=√{ 4Q/(14U3600)}U=Q*4/{ (D/2)^2*14*3600}.
