A fan is a key component of any HVAC system. The most common HVAC fans are axial, forward-curved centrifugal, and backward-inclined, and each is uniquely suited to certain purposes. It’s important to understand each fan’s differences in energy efficiency, cost-effectiveness, and noise considerations. The wrong fan for the job could lead to reduced functionality and higher costs. Here’s what you need to know about the various fans for HVAC systems.

Axial Fans

Axial Fans, which include propeller, tube axial, and vane axial styles, move an air stream along the axis of the fan. These fans work like an airplane propeller—blades generate an aerodynamic lift that then pressurizes the air. Propeller fans embody only a motor and a propeller used to drive the airflow. Similar to a propeller fan, a tube axial fan includes a venturi that surrounds the fan propeller and is designed to reduce the air leak

age or vortices created by the spinning prop. A vane axial fan features vanes trailing the rear of the propeller, which straighten out the swirling airflow that occurs when the air is accelerated by the motor. Axial fans are inexpensive, compact, and light, making them a favorite for industrial applications. They are, however, usually noisier than centrifugal fans. Noise can be abated by insulating the duct; mounting the fan on soft materials like rubber or using a spring isolator to reduce the amount of transmitted vibration; or installation of sound dampening material or baffles.

Centrifugal Fans

Centrifugal Fans, which are categorized by their radial, forward curved, or backward inclined blade shapes, increase the speed of an air stream with a rotating impeller. The speed increases as the air reaches the ends of the blades and is then converted to pressure. These fans are able to produce high pressures, which makes them suitable for harsh operating conditions, such as systems with high temperatures or moist or dirty air streams. Tip vortices or tip leakage flow produced by the pressure differential across the airfoil section can be problematic with these basic fans.

Forward-Curved Centrifugal Fans, look more like hamster wheels and can create more air pressure. Because of this, they tend to be noisier than axial fans and require more power to run. They are durable, easy to clean and maintain, and have less problems with resistance. Forward-curved centrifugal fans are also called blowers.

Backward-Curved Centrifugal Fans are uncommonly shaped blades, which can be curved or straight, make these fans excellent for high volumes of airflow and variable resistance. They are often used for industrial purposes.

Applications of Fan Types

Though axial fans are usually the least expensive, they’re not the right solution for every situation. Because of their features and capabilities, they are best for compact electronics, automotive products, medical devices, and appliances as well as large applications such as cooling towers, vending machines, outdoor air conditioner compressors, and combustion engine cooling. Axial fans are also ideal as general-purpose fans.

Centrifugal fans are better for larger systems: air-handling units, air pollution and filtration systems, and drying systems. With incredible energy efficiency and versatility, these fans come in a variety of models, so you can find one to fit into a small, hard-to-reach space. They are also great options for dust collection, glass tempering, and incineration systems.

Choosing the right fan for your HVAC system is essential for its efficiency and performance. An axial fan, for example, won’t do as good a job managing the resistance compared to centrifugal fans of the same size in an air filtration system. Using an axial fan for that purpose would make the system perform poorly and likely lead to extra maintenance and repairs. Even though it would be less expensive initially, it would cost you more in the long run and would not function the way you would expect from such a system. Likewise, using a centrifugal fan in a cooling tower where it’s not needed would lead to unnecessary noise and increased costs.

Brushless DC fans and blowers need optimal motion control. When complex or demanding applications need precise levels of output, intelligent motion control systems can keep parts safe while still ensuring high-quality production cycles. These intelligent motion controls (IMCs) have in-board circuits that use programmable, information-gathering features to develop air movement “intelligence” and learn how the parts need to operate in different environments.

IMCs are ideal for:

• Green applications in which facility managers want to improve reliability, the equipment’s life expectancy, and energy efficiency.
• Systems that need consistent monitoring and cooling—IMCs have multi-alarm connections to prevent complete system failures, reduce voltage fluctuations, and have more reliable control.

When businesses install IMCs, they will make their facilities greener and more efficient. Read on to learn about all the different benefits IMCs can bring.

Top Solutions

There are several different types of IMCs that can add control to the operation and maintenance of brushless DC fans and blowers. The top four IMC solutions are:

Rotation Detectors

A smart rotation detector can monitor fan operations in parallel circuits to detect ongoing circulation as well as potential failures or stopped fans. These systems give a “high” output signal to the monitoring interface while the fan rotates. That same signal turns to “low” or “off” based on the fan’s status. This allows operators and maintenance teams to investigate potential problem areas more quickly because the system automatically notifies them when a fan stops working rather than requiring them to monitor changes in temperature.

Rotation detectors use the same hardware as the frequency generator (tachometer), which we also describe below. Once the detector is added to an array of fans, it operates as part of the facility’s multi-alarm connection.

Inrush Current Protection

When motors, heating elements, transformers, and power supplies turn on, the current surges. This short-lived inrush current can damage electronic parts if it isn’t properly controlled.

Facility managers use inrush current protection to slow the flood of current to the equipment. This technology allows fan blades to speed up at a more gradual rate through incremental increases of current. The process takes approximately ten seconds during startup, and it protects both the circuits and the moving parts from damage.

Auto Start

Sometimes, fan blades get blocked by temporary obstructions. Auto starts control the current output in these circumstances. First, the current can be reduced to zero when an obstruction is detected so the fan blades don’t damage themselves. This feature is called locked rotor protection. Then, the auto-start control uses a second feature, restart with current limit, to guarantee the restart of the rotor once it is released.

Frequency Generator (Tachometer)

This IMC solution is an open collective output type that produces an analog voltage based on the fan’s motor speed. These parts provide feedback and can be used to measure the speed of motors, rotors, and engines.

Frequency generators use the same hardware as rotation detectors, and they’re powered by the power supply voltage. A tachometer will send a square wave signal to the reading device if the collector connects with a pullup resistor. This part can handle a maximum collector voltage of 72 V DC and current of 10 mA.

Automation technology has improved by leaps and bounds recently, allowing manufacturers to more efficiently cut expenses and avoid maintenance delays. In the industrial fan and blower field, recent advances have allowed facility managers a greater degree of automation ability over their brushless DC fans and blowers.

Now, industrial fans and similar applications can use intelligent motor controls (IMCs) to better respond to environmental and electrical changes without human intervention, which helps reduce maintenance and labor costs associated with this equipment.

Today, we’re going to answer some common questions about the use and functionality of IMCs in industrial applications.

Will IMCs Increase Product Life and Productivity for Industrial Fans?

For many industrial manufacturers, implementing IMCs on their industrial fans has led to rapid profit growth. IMCs allow manufacturers to automate their fans’ control features, which helps minimize risks associated with power and heat incidents. Installing IMCs also adds a number of core features that make their product uniquely useful to industrial clients.

Both design engineers and system users need cooling systems that protect them against a multitude of safety issues. IMCs can help with the following problems associated with fan equipment:

· Current surges: IMC Inrush Current Protection (IR) control features help avert critical failures caused by current surges.

· Power supply: By ensuring that the power supply voltage never increases over the 20% specified rated voltage (which also can be customized), IMCs prevent issues resulting from power supply overvoltage.

· Blade blockage: The IMC Auto Start (AS) Control with Locked Rotor Protection and Restart with Current Limit system will automatically restart your fan should the blade get blocked. Built-in rotation detectors and life detectors can indicate whether the blade is running (with both low and high signals).

· Aging or wear: Automatic Temperature Control, Manual Variable Resistor Control, Programmable Constant Speed Control, and Multi-Alarm Connections help ensure that your fans run at optimal speeds and control parameters, which increases their total life.

In addition to these features, operators can program the systems so that they can automatically shift their behavior in response to environmental factors and sudden power changes. In this way, your industrial fans can act in the same way as AC units, which automatically calibrate their outputs to a room’s conditions—but IMCs do so at a fraction of the cost.

What Do IMC Systems Protect?

While we’ve already covered the basics, let’s dive into some specifics. Here are 16 ways ICM systems help protect against multiple safety and performance issues.

1. Inrush Current Protection (IR): This causes a gradual current increase in speed until the fan has achieved its maximum speed at the rated current (within 10 seconds)

2. Auto Start (AS): The blade will automatically restart if it’s blocked, and the fan’s current is reduced to zero if the rotary is locked at any point

3. Rotation Detection (RD): This indicates whether the blade is rotating on a LOW signal

4. Frequency Generator (FG): This monitors the fan’s speed for safety issues

5. Rotation Detector Complement (RDb): This indicates whether the blade is rotating on a HIGH signal

6. Life Detection (LD): The LD helps detect whether the fan blades are turning below 70% of their rated target speed, which can indicate aging or wear

7. DC Voltage Signal (VPWM): This safely controls speed via an external DC voltage signal

8. Current Source Signal (IPWM): This controls speed via an external current source signal

9. Pulse Width Modulation Signal (PPWM): This allows you to control speed via a PWM signal (30 Hz to 30 KHz)

10. Over-Voltage Protection (OV): This feature protects the power supply from over-voltage issues

11. Automatic Temperature (TPWM): Similar to thermostats, this automatically controls speed via an NTC thermistor, which can be used to monitor and automatically control overheating issues

12. Manual Variable Resistor (RPWM): This controls speed via an external resistor

13. Current Limit (CL): This feature helps limit the current of the fan during a restart

14. Fixed Constant Speed (CSf): This ensures that your fan maintains optimal speed over a wide voltage range

15. Programmable Constant Speed (CS): This also ensures that your fan maintains speed over a wide voltage range, and it can be essential to overcoming system impedance variations

16. Multi-Alarm Function: This helps monitor the overall state of multiple fans and can alert you to issues immediately—before they become expensive problems

Positive temperature coefficient (PTC) heaters consist of specialized heating discs built from advanced ceramic materials. These safe, powerful, and energy-efficient heaters allow for exceptional heat production and transfer within even the smallest spaces.

PTC heaters fall into one of two categories: fin elements or honeycomb forms. While both types offer a wealth of benefits over conventional heaters, users should be aware of the strengths and weaknesses of each before deciding which option to go with.

FIN PTC Air Heater

FIN PTC air heaters are self-regulating systems that employ temperature-limiting effects that remove the risk of overheating. Because of these self-regulating features, FIN PTC air heaters always operate at the highest safety levels possible. These conditions also allow for better conductivity and higher efficiency, resulting in a longer lifetimes than other heating systems.

These machines circulate air through the use of large aluminum fins, whose surface area ensures homogeneous heat transfer with low outlet. Users can also adjust the airflow volume to automatically regulate the system’s heating power at any given time.

Honeycomb PTC Air Heater

Honeycomb PTC air heaters function below the combustion point of paper, meaning that they’re incredibly safe and energy-efficient for everyday use. In these units, small heating discs function as the heating element, connecting directly with the power source to convert electricity into heat.

Holes in each disc allow for greater airflow access, meaning that these heaters can process higher volumes of air than other heating systems. Honeycomb assemblies can hold three, four, or five discs at a time to produce up to 2,000 watts of heat output.

Applications of PTC Heaters in Various Industries

· Transportation: PTC heaters bring a wide variety of benefits to the automotive and aerospace industries. These systems provide compact, lightweight means to heat the interiors of planes and vehicles. Anything from seat and steering wheel heaters to plane de-icers will likely use a PTC heater.

· Healthcare: Because PTC heaters’ high safety records, medical workers frequently turn to them for a variety of applications. PTC heaters work especially well as under-body heating systems on operating tables, gurneys, and beds.

· Recreational: Outdoor clothing manufacturers can weave PTC heaters into their clothing. Because of their ability to run open-loop (without the use of electronic controls), jackets, vests, socks, and gloves can all incorporate PTC heaters.

· Food and beverage: PTC heaters can keep foods and fluids at consistent temperatures while they’re being transported or stored for later use. These systems appear at many stages of the food processing and distribution process—processing plants, food transportation, and restaurants all benefit from PTC heaters.

· Public spaces: PTC heaters provide efficient, portable methods to heat outdoor venues such as restaurant patios, stadiums, and convention centers. Because of their light weight and energy efficiency, they can be moved and repositioned as needs and weather conditions change.

PTC Heaters Will Improve Your Home and Business

Dealing with dangerous and unreliable heaters can be stressful. PTC heaters improve on previous heater designs to provide safe, energy-efficient heating systems for applications large and small. Understanding the benefits to these heaters over traditional coil or ceramic chip options can help make a world of difference in both safety and effectiveness.

High-performance blowers are a critical aspect of keeping a plant or factory running; smaller and more compact options are also useful in the average family home. These types of blowers ensure that air can move continuously while maintaining an energy-efficient level of operation.

High-performance blowers provide increased airflow, which reduces the amount of cold spots in the home and improves the performance of humidifiers and air purifiers. They also feature nearly silent motors, so you may not even hear the system running.

Applications and Uses of High-Performance Blowers

Blowers are common in plants and factories because they help combat pressure rising in pipes that feature components such as filters, grates, valves, heaters, and condensers. They are often deployed with fairly narrow pipes to promote a higher and stronger flow; this can be especially beneficial in scenarios where fumes need to be removed from an area.

Air velocity is also an asset in:

• Transporting bulk goods
• Accelerating evaporation
• Scraping products with air knives
• Blowing off production scrap
• Cooling
• Diving areas
