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 typical supply ventilation system has a fan and duct system that introduces fresh air into usually one -- but preferably several -- rooms that residents occupy most (e.g., bedrooms, living room). This system may include adjustable window or wall vents in other rooms. Also, energy recovery ventilation systems operated in cold climates must have devices to help prevent freezing and frost formation. Very cold supply air can cause frost formation in the heat exchanger, which can damage it. The cold outside air is filtered, receives the energy of the warm exhaust air in the heat exchanger and then travels to the apartment as supply air. The used exhaust air is discharged as exhaust air from the house, but not without having transferred the energy in the ventilation unit to the supply air.

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.
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.
Why heat recovery ?
After fabrication and installation, a well-designed ventilation system removes the contaminated air in minutes. Even faster in some cases, depending on the size of the room and fans. The flow and diffusion of smoke is mainly influenced by factors such as wind pressure and thermal pressure. There are many types of dust removal equipment, including baffle dust collector, cyclone dust collector, bag type dust collector and spray tower dust collector and electric dust collector etc. 4) The turning near the outlet of the fan must be consistent with the direction of rotation of the fan impeller to make the air flow unobstructed and even and avoid unnecessary energy loss. According to different occasions, it is possible to change the installation angle, the number of blades, the rotational speed, the machine number and other methods to meet the requirements of various uses.
Exhaust ventilation systems are most appropriate for cold climates. In climates with warm humid summers, depressurization can draw moist air into building wall cavities, where it may condense and cause moisture damage. Good arguments therefore speak for ventilation systems with heat recovery . When all we can have is just a small window, then cross ventilation becomes a major concern, especially in small bathrooms.
Air Ventilation Systems in India
INAIR – fresh air systems for home aims to fill every indoor space with high quality fresh air along with low energy consumption. This system is used in areas where contaminants are higher and pose a greater risk to employees and others inside the workspace. This system can handle removing many kinds of pollutants including metal fumes and dust. By cleaning air contaminants, removing dust fumes, and bringing in large amounts of fresh air, ventilation system is one of the first lines of defense against sickness.
If you use an air conditioner, an energy-recovery ventilator generally offers better humidity control than a heat-recovery system. However, there's some controversy about using ventilation systems at all during humid, but not overly hot, summer weather. Some experts suggest that it is better to turn the system off in very humid weather to keep indoor humidity levels low. You can also set up the system so that it only runs when the air conditioning system is running, or use pre-cooling coils. Another smart way to improve ventilation in your house is to use bamboo furniture pieces as due to their airy construction, they act as agents of wind and do not retain heat. Once installed indoors, they play a significant role in maintaining good airflow every time you open the doors and windows.
Wind pressure refers to the pressure generated when the wind blows to the external surface of a building, due to which the air flow is hindered, the speed is reduced and part of the kinetic energy is transformed into static pressure. For cities with serious air pollution and noise pollution, direct natural ventilation will also bring polluted outdoor air and noise into the room, which is not good for human health. Hot-pressing is caused by the temperature difference between indoor and outdoor air, which is known as the “chimney effect”. In the entire control space, trying to make the indoor airflow uniform and reducing the existence of eddy currents are needed to avoid the accumulation of pollutants in local areas. We are highly engrossed in offering a quality assortment of Axial Flow Fan. The offered fan is extensively used for external or internal and designed to attain a high level of air ventilation.
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.
We do it to protect our home and family from insects and mosquitoes. It will protect your home without obstructing beautiful views from the balcony. This revolutionary system inhales outdoor air & filters it automatically to pump-in “PURE FRESH AIR” in your Home/Office & also exhale stale air and pollutants simultaneously. Thus the indoor air is absolute “Fresh Air” and NOT just recycled stale air as in the case of using portable air purifiers. MECH Engineers was established in the year 1985 with a aim to provide cost effective and best-known quality Air Ventilation System and its related products.
The electromagnet and motor action of the control actuator or the control pneumatic actuator can close the valve under the action of the spring force or close the valve by the rotation of the motor. The pipes, thermal insulation materials, noise-absorbing materials and adhesives used in the ventilation and air-conditioning pipeline engineering shall be made of non-combustible or non-combustible materials. When a fire occurs, the temperature inside a high-rise building is much higher than the outdoor temperature.
