The centrifugal force generated by the spinning vanes, creates a low-pressure region which helps in suction of the air. Air drawn out by the suction action is continuously replaced by the fresh air from outside. Easy to install, these ventilators have very low maintenance cost. In the summer, an energy-recovery ventilator may help to control humidity in the house by transferring some of the water vapor in the incoming air to the theoretically drier air that's leaving the house.
The smoke refers to the floating state of solid and liquid particles in the air produced by incomplete combustion of substances. The purpose of fire prevention is to prevent the spread of fire and extinguish the fire. The equipment for this treatment process is called dust removal equipment.

A well-designed ventilation system results in better health for your employees as well as reduced risk for workplace accidents. Coupled with the greater influence of the height of the high-rise building shaft, the hot-pressure increases significantly, and the smoke will spread upward along the building shaft. The distance between the bottom of the air inlet and the outdoor ground is generally not less than 2cm to avoid inhaling ground dust. 5) There should be a straight pipe section with a diameter of less than 3D from the outlet of the fan to the turn to avoid unnecessary static pressure loss. The connecting pipe of the inlet and outlet of the fan has a great influence on the performance of the fan. The air duct should be provided with necessary adjustment and measuring devices or reserved for the interface of the measuring device.
Fresh air supply and exhaust vents can be installed in every room to ensure a contant flow of fresh air required as per the ASHRAE norms while venting out the indoor air. The units are fitted with HEPA filters to ensure outdoor air is filtered before it enters indoors. Energy recovery fresh air units retain 80% of the energy from the indoor air which is used to cool /warm the air coming indoors to maintain ambient indoor temperatures. Exhaust ventilation systems are relatively simple and inexpensive to install.
Heating Ventilation Air Conditioning System
It is an economical and effective ventilation method for workshops with a lot of waste heat. It is recognized by its inherent nature to utilize the natural force of wind to draw heat and moisture out of the roof. In view of the many advantages, your customers' decision should not be "heat recovery yes or no", but only what type of heat recovery.
For most houses, attempting to recover all of the energy in the exhaust air will probably not be worth the additional cost. Also, these types of ventilation systems are still not very common. Only some HVAC contractors have enough technical expertise and experience to install them. The filtered supply air and the used exhaust air are completely separated from each other. A countercurrent heat exchanger can best develop its high efficiency of up to 90 percent where the outside temperature does not or does not fall below its specific frost point (-3 ° C at 90% efficiency) for a short time.

The trick is in selecting the right style of ventilator window, like it is done here. The shutter of the window, when open, will horizontally divide the window in two parts. Hot air will leave the room from upper portion since warm air has the tendency to move up and cool air will rush to fill the empty space from the lower opening. There will be sufficient supply of fresh air even through the small vent. Believe it or not, we Indians avoid opening our windows and prefer to keep the air-conditioning running. It’s not that we don’t like fresh air or cut down on our electricity bills.
This is manufactured under the guidance of our adept experts with optimum grade materials and advanced techniques keeping in mind industry standards. Because they directly supply outside air, balanced systems allow the use of filters to remove dust and pollen from outside air before introducing it into the house. Balanced ventilation systems, if properly designed and installed, neither pressurize nor depressurize your home. Rather, they introduce and exhaust approximately equal quantities of fresh outside air and polluted inside air.
Dilution systems require less maintenance and are the best ventilation choice for mobile or dispersed contaminant sources. Mechanical smoke prevention is a smoke prevention technology that adopts a mechanical pressurized air supply method to control the flow direction of the flue gas by the gas flow and pressure difference generated by the fan. Air Ventilation is the intentional movement of air from outside a building to the inside. Air Ventilation used for providing acceptable indoor air quality. The vents or flues carry the impurities to be expelled from the building, in a way which does not cause harm to the occupants of the building.
With their presence, the harmful toxins in the air also get eliminated. Now imagine using wind which is natural, free, healthy and refreshing to regulate the heat of your home and making it free from ‘stale’ air. Thecountry homes still have the access to fresh air with windows and doors build adjacent or opposite to assist in cross ventilation. However, in modern homes which are small and cramped up, the challenge is to make it well- ventilated.
Energy recovery ventilation systems provide a controlled way of ventilating a home while minimizing energy loss. They reduce the costs of heating ventilated air in the winter by transferring heat from the warm inside exhaust air to the fresh outside supply air. In the summer, the inside air cools the warmer supply air to reduce cooling costs. Like exhaust ventilation systems, supply ventilation systems are relatively simple and inexpensive to install.
For this these Air Ventilation Fan are being utilized to create natural of forced draft in the open area. These fans are much useful to increase the air cycles in the required area. These pollutants are a particular concern when bath fans, range fans, and clothes dryers are run when an exhaust ventilation system is also operating. The exhaust system has an air intake area, ducts that move air from one area to the next, an air cleaning device, discharge stacks, and fans. Both ends of the system work together to remove a wide range of contaminants from the area. During a fire, if a window is on the windward side of the building, the wind pressure effect can cause smoke to quickly spread throughout the lost floor and even blow it into other floors.
The connection with the air duct should be reasonable to reduce resistance and noise. This series of fans can be divided into single-speed fan and double-speed fan. The type of blade has the airfoil twisted blade or straight blade; equal-thickness twisted blade or straight blade. The amount of hot-pressing depends on the difference in height between the two openings and the difference in air density between inside and outside.
They need to be cleaned regularly to prevent deterioration of ventilation rates and heat recovery and to prevent mold and bacteria on heat exchanger surfaces. Because an energy-recovery ventilator transfers some of the moisture from the exhaust air to the usually less humid incoming winter air, the humidity of the house air stays more constant. This also keeps the heat exchanger core warmer, minimizing problems with freezing. The mechanical exhaust is a mechanical exhaust method, which uses the gas flow and pressure difference produced by the fan to exhaust the flue gas or dilute the concentration of the flue gas by using the exhaust pipe. In some large buildings, due to the long ventilation path, large flow resistance simply relying on natural wind pressure and heat pressure is often not enough to achieve natural ventilation.
The correct size duct is necessary to minimize pressure drops in the system and thus improve performance.Insulate ductslocated in unheated spaces, and seal all joints with duct mastic . May require mixing of outdoor and indoor air to avoid drafts in cold weather. Oxygen decrease and carbon dioxide cause stuffiness in the premises.
