Description
What is an air curtain?
An air curtain is a device that uses a fan to create an invisible air barrier on the door to separate two different environments without restricting access to people or vehicles.
Energy-saving air screens reduce heating and cooling costs by up to 80% while protecting the indoor climate and increasing people’s comfort.
Protects the atmosphere from pests and insects, dust, air, pollution, odors, odors, and prevents winds and the entry of cold or hot air.
The operation of the air curtain is based on a high-speed air jet that covers all openings. Hot air curtains provide comfort to people when they pass through the air jet by air jets and help maintain the temperature at the inlet.
How do ParsaFan air curtains work?
Advantages of ParsaFan air curtain
Commercial profitability
- Increased sales due to the “open door effect”. It is clear that when the doors are open, the wealth of the people increases significantly
- Open doors are an invitation to customers
- The gateway acts as a shop window and allows people to see inside the shop
- Free access for people with disabilities (wheelchairs) or people who use strollers, wheelchairs, umbrellas, etc.
- Increases usable space at the entrances
- Increases the comfort of customers and employees
Hygienic and healthy environment
- Helps maintain a good environment
- Reduces staff absenteeism
- Pest and insect control
- Barrier against air dust, pollution, smoke and bad smell
energy saving
- Reduces energy losses from conditioned space
- Reduction of central power plant capacity (heating / cooling)
- Reduces current building costs
- Reduces CO 2 emissions
Increase safety
- Increase vision and avoid collisions because there is no physical obstruction
- In cold rooms, it reduces fog, dries the door and prevents ice from forming on the floor
- Easy evacuation through the exit door in case of fire or emergency
- Act as a barrier against fire smoke (special application)
Applications of ParsaFan air curtain
Door weather protection
First of all, air curtains are designed to prevent air from invading an open area (hot or cold) outside an open door.
ParsaFan air curtains reduce energy costs by keeping hot or cold air inside the building.
Efficient air curtains save up to 80% in energy consumption across the door compared to unopened doors.
During the winter, an air curtain creates a barrier that lets in cold air, while in summer, a stream of hot air blows out.
Considering the stored energy, the average repayment time of the air curtain is between 2 to 5 years, depending on the conditions of usage and the weather.
flying pests and insects controls
Insect air curtains are usually used when necessary to prevent insects from entering buildings such as food processing plants, bakeries, restaurants, hospitals, etc. Insects are stopped as they approach the flight by a very powerful air barrier to penetrate.
You need to choose the right air curtain for insect repellent applications. A very powerful air jet is required along all doors (more powerful than conventional applications).
Cold storage
Due to the large temperature difference, the installation of air curtains is highly recommended to reduce energy losses when the door is open. The greater the temperature difference between inside / outside, the greater the energy loss when the door is unprotected.
So the air curtain repayment period is very short and then the energy / money savings are huge.
Parsa Fan Company not only saves money by avoiding the transfer of air through the door, but also keeps frozen goods in excellent condition and helps reduce the cost of cold room defrosting.
For cold rooms and freezers, air curtains are the safest way to protect against energy loss without any physical obstruction that could cause an accident or collision at the door. For example, when plastic tape curtains are used, visibility is restricted across the door and accidents to people or vehicles occur, with damaging consequences. In addition, it prevents annoying and potentially dangerous fog, moisture and ice formation at the entrance.
Dust, pollution and air control of clean rooms
Air curtains, which are always installed in the clean part of the door, act as a barrier against dust, particles and moisture.
Common places where air curtains are installed:
the buildings
Airports
Train stations
hospitals
Universities
museums
Chain supermarkets
factories
Hotels
restaurants
To choose a Parsafan air conditioning , the following factors must be considered:
The installation height is measured from the drain diffuser to the floor
Door width
Location of the building to determine the level of protection required against weather conditions (temperature, humidity and wind)
If the building has several doors in one area, the view is different or opposite
If the building has several floors that are connected by an escalator / staircase
Pressure difference between inside and outside the building
Door Specifications: If always open, opens automatically, opens manually, revolving door, etc.
Features of ventilation and air conditioning installation
Availability of voltage and electrical power
Business type, style and location decoration
Free hanging or recessed, horizontal or vertical installation, heated or unheated and so on.
Some installations with strong wind conditions may endanger the air curtain due to: strong wind, severe temperature difference inside / outside, more than one door, different levels, large halls, high pressure difference, etc.
In this case, a higher performance model is recommended.
Control and adjustment of ParsaFan air curtains
Air curtain control is necessary to prevent unnecessary energy consumption by changing the function of the air curtain according to the position of each moment.
Using proper control with assistive devices, the user can adjust the airflow to optimize the barrier and prevent air infiltration across the port.
The main controllers allow you to change the ventilation speed and heating steps manually.
Advanced controllers may include options such as the following:
Auto function: change ventilation and / or heating depending on the situation
Connection to sensors and / or external devices including internal sensors (temperature, motion, etc.)
Interface connection to BMS systems, external ON / OFF, thermostatic control …
Internal security programs (protection of components and prevention of damage)
Door contacts, valves, antifreeze sensors and so on.
The main controllers allow the ventilation speed and heating stages to be changed manually.
External sensors and devices help control and modify the operation of the air curtain to protect the unit and be more efficient in any situation.
For example, if we install a door contact connected to the air curtain, when the door is closed, the air curtain is off or operates at a low ventilation rate and / or low heating stage, saving energy consumption. When the door is opened, the air curtain increases the ventilation speed and / or heating stage to protect the door.
Another example is connecting an air curtain to a room thermostat. The device then increases / decreases or stops the heating when it reaches the desired temperature.
Airtecnics has a wide range of controllers from standard manual controls to advanced automatic functionality and an interface for connecting air curtains to BMS systems.
In addition, we offer a wide range of accessories: all kinds of supports, room thermostats, door contacts, solenoid valves, anti-freeze sensors and so on.
