Have you ever watched wisps of smoke drifting from smokestacks and wondered how much energy they’re uselessly pumping into the air? Maybe less than you might think! Saving energy is a huge and costly problem for factory bosses and it’s one reason they often install devices called heat exchangers to salvage as much heat as possible from waste gases. Heat exchangers have lots of other familiar uses too. Engines in cars, ships, and planes use heat exchangers to work more efficiently, and if you have a refrigerator or an air-conditioner in your home, those are using heat exchangers too. So what exactly are heat exchangers and how do they work? Let’s take a closer look! Fan cooled heat exchanger Baton Rouge Louisiana.

Heat exchangers are used in many engines and machines to improve their efficiency. Fan cooled heat exchanger Baton Rouge Louisiana.

What is a heat exchanger?

Suppose you have a gas central heating furnace (boiler) that heats hot-water radiators in various rooms in your home. It works by burning natural gas, making a line or grid of hot gas jets that fire upward over water flowing through a network of pipes. Fan cooled heat exchanger Baton Rouge Louisiana. As the water pumps through the pipes, it absorbs the heat energy and heats up. Fan cooled heat exchanger Baton Rouge Louisiana. This arrangement is what we mean by a heat exchanger: the gas jets cool down and the water heats up. Fan cooled heat exchanger Baton Rouge Louisiana.

A heat exchanger is a device that allows heat from a fluid (a liquid or a gas) to pass to a second fluid (another liquid or gas) without the two fluids having to mix together or come into direct contact. If that’s not completely clear, consider this. In theory, we could get the heat from the gas jets just by throwing cold water onto them, but then the flames would go out! The essential principle of a heat exchanger is that it transfers the heat without transferring the fluid that carries the heat. Fan cooled heat exchanger Baton Rouge Louisiana.

How does a simple heat exchanger work? A hot fluid (shown in red) flows through a tube coiled inside a larger shell through which another, colder fluid (shown in blue) is running in the opposite direction. Heat is exchanged by the fluids: the hot fluid cools down and the cold fluid warms up, without them actually coming into contact and mixing. This is a simplified example of a shell and tube exchanger: generally, heat exchangers of this design have many thin tubes running through a large shell.

You can see heat exchangers in all kinds of places, usually working to heat or cool buildings or helping engines and machines to work more efficiently. Refrigerators and air-conditioners, for example, use heat exchangers in the opposite way from central heating systems: they remove heat from a compartment or room where it’s not wanted and pump it away in a fluid to some other place where it can be dumped out of the way. Fan cooled heat exchanger Baton Rouge Louisiana.

Before choosing a ventilation fan, make sure it’s one that will be adequate for the size of your bathroom. You’ll also want to prioritize your wants and needs with regard to noise level and features so that you’ll get maximum satisfaction for your budget. Fan cooled heat exchanger Baton Rouge Louisiana.

Proper Venting

Unfortunately, bathroom ventilation fans often are set up so that the exhaust air to the space between ceiling joists, especially if the bath is located on a lower level toward the middle of the house. Venting to the space between joists or into an unheated attic simply dumps excess moisture into the worst possible conditions—closed, dark spaces where humidity condenses on cold surfaces and mold can spread, damaging floors, walls and ceiling materials. Fan cooled heat exchanger Baton Rouge Louisiana.

A smarter, healthier alternative is to connect your bathroom exhaust fan to vent ducts that channel the exhaust outside your home. Building codes typically specify this solution; regardless, it’s the most sensible and safest method. Fan cooled heat exchanger Baton Rouge Louisiana.

Keep in mind that properly vented ventilation fans also suck a lot of heated air out of your house. A remedy is to install a heat-exchange ventilator fan. These fans use warm, outgoing air to heat cooler, incoming replacement air. Heat exchanger models sell for about twice as much as standard bathroom ventilation fans. Fan cooled heat exchanger Baton Rouge Louisiana.

Bathroom Ventilation Fans

Air Flow Capacity

Bathroom ventilation fans have different airflow capacities, measured in cubic feet per minute (cfm). To get the right fan for your bathroom, use the guidelines set by the Home Ventilating Institute: Your fan should have 1 cfm for every square foot of floor space in your bathroom. Fan cooled heat exchanger Baton Rouge Louisiana.

For bathrooms larger than 100 square feet, figure your cfm requirements by adding:

• 50 cfm for every toilet
• 50 cfm for each shower, bath and combo
• 100 cfm for each whirlpool
• Noise Level
• Fan noise is rated by sones—a scale that represents degrees of loudness. A rating of 0.5 to 1.2 sones means the fan is exceptionally quiet. Ratings of 1.5 to 2.0 sones is very good. Fans rated in excess of 4.0 sones tend to be noisy.

Smart Options

Motion sensor activation turns on the fan when someone enters the bathroom. The fan speed can be pre-set to a low volume to remove the moisture of everyday tasks, such as shaving, and switch-activated for high-volume tasks, such as showering. Fan cooled heat exchanger Baton Rouge Louisiana.

Overhead lighting can be switch-activated or turned on by a motion sensor.

• Nightlight equipped models to use a low-wattage light to help you find your way in the dark.
• Humidity sensing ventilation fans automatically switch on when the unit detects high levels of humidity.
• Built-in heaters, typically infrared heat lamps, add a little extra warmth when it’s chilly outside.

Energy Efficiency

Bathroom ventilation fans that earn an EnergyStar label for the efficient operation must be independently certified by the Home Ventilating Institute or the Air Movement and Control Association. The standards apply to any lighting options, too. EnergyStar ventilation fans use about 60 percent less energy than standard fans. Fan cooled heat exchanger Baton Rouge Louisiana.

Many of today’s bathroom ventilation fans feature quiet motors that let them perform at extremely low noise levels. These same motors are designed for energy efficiency. Panasonic’s WhisperGreen line of ventilation fans, for example, employ a DC (direct current) motor that’s quieter and more energy-efficient than EnergyStar criteria. Fan cooled heat exchanger Baton Rouge Louisiana.

In some states, bathroom ventilation fans are required to meet building codes. In California, for example, Title 24 sets guidelines for the overall energy efficiency of new homes and additions. Bathroom ventilation fans are part of the HVAC systems that must be evaluated for energy efficiency under Title 24 before building permits can be issued.

Panasonic pleased to offer the most technologically advanced and energy efficient ventilation fan. WhisperGreen Select allows you to customize the fan to suit your customers’ particular needs. Fan cooled heat exchanger Baton Rouge Louisiana.

As with all Panasonic fan and fan/light units, the WhisperGreen Select UL listed for installation into a tub or shower enclosure when GFCI protected.

It best to have an idea how you or your customer would like the WhisperGreen Select fan to operate before you start the installation. Depending on the desired function, you can choose from one of three wiring methods. Fan cooled heat exchanger Baton Rouge Louisiana.

We’ll cover the three methods in this tutorial and explain the fan’s operation with each method. Fan cooled heat exchanger Baton Rouge Louisiana.

Fan cooled heat exchanger Baton Rouge Louisiana

Before we get started on wiring methods, it’s important to note that every base model WhisperGreen Select is three fans in one right out of the box. Fan cooled heat exchanger Baton Rouge Louisiana.

You’ll find a CFM selector switch on the fans motor plate which allows you to set the speed of a WhisperGreen Select fan (50-80-110 or 110-130-150 CFM, depending on the model). Fan cooled heat exchanger Baton Rouge Louisiana.

Simply select the speed you would like the fan to operate at by moving the selector switch to the desired CFM. Fan cooled heat exchanger Baton Rouge Louisiana.

Upon opening the fans junction box cover, you will find that the WhisperGreen Select contains a black, white, and green wire leads along with two red wire leads on the fan only. Fan cooled heat exchanger Baton Rouge Louisiana.

The fan/light units have an extra black and white lead for the light kit.

Please note: you will need to adhere to and obey all local wiring codes.

Method 1: only control fan from wall switch

The first method is the most basic installation method. In this use, we’ll be wiring the fan for on and off using as a spot ventilation fan, and we’re not looking to add any of the plugs and play modules for the WhisperGreen Select. Fan cooled heat exchanger Baton Rouge Louisiana.

Bring power from the panel to a wall switch.

At the wall switch, attach the wire to the power conductor (the black cable) at the line side of a single-pole switch. Fan cooled heat exchanger Baton Rouge Louisiana.

From the switch, continue the run with the power conductor—again, the black cable—connected to the load side of the switch up into the fan junction box connected to the black conductor from the fan’s motor. Fan cooled heat exchanger Baton Rouge Louisiana.

The neutral conductors, the white cables, connect together at the switch box and continue to the junction box where it is conducted to the white lead in the junction box.

The ground wires are brought up to the wall switch continues up to the ground lead, the green wire, from the junction box. Fan cooled heat exchanger Baton Rouge Louisiana.

The two red wires remain untouched. There is no need to do anything with them.

When using this method, it’s important to note that if you choose to have any of the plugs and play modules at a later time, they will only work if the on the switch is in the ‘on’ position. Otherwise, there will be no power to the fan. Fan cooled heat exchanger Baton Rouge Louisiana.

Method 2: Automatic operation

Using this method, you would be using the motion sensor module and/or the condensation sensor to either turn the fan on or off. Or, if using the continuous run module to boost the fan from low to high speed. Fan cooled heat exchanger Baton Rouge Louisiana.

If you choose this wiring method, you will not have manual control of the fan. You will be relying on the sensors only to control the fan. Fan cooled heat exchanger Baton Rouge Louisiana.

• Bring power from the source directly to the fans junction box.
• Bring the power lead (the black conductor) to the power lead for the fan’s motor
• The Neutral lead (the white wire) to the white lead in the fans junction box
• And the bare ground wire to the green wire in the fan junction box.
• Leave the red wires capped separately and tucked into the junction box.

Method 3: Manual control with wall switch and sensor controls

The third method we’ll discuss is for manual control of the fan with a wall switch in conjunction with any of the plug and play modules.

• Bring power from the source directly to the fans junction box.
• Bring the power lead (the black conductor) to the power lead for the fan’s motor
• The Neutral lead (the white wire) to the white lead in the fans junction box
• Attach the bare ground wire to the green wire in the fan junction box.
• The red wires are signal wires that designed to turn the fan from standby to ‘on’ or from low to high speed if using the continuous run module. They NOT designed to carry current, DO NOT attach power to these conductors. These conductors connected to either side of a standard single pole switch.
• Turning the switch to the ‘on’ position allows the fan to turn on or boost from low to highly completing the signal loop to the fans motor.

With this wiring method, you can still use both the motion sensor and the condensation sensor modules as secondary control however, please note that these controls will only be active when the wall switch is in the off position. Fan cooled heat exchanger Baton Rouge Louisiana. With the switch in the on position, the signal loop will completed and the fan will, in the active mode. The motion sensor and/or condensation sensor will not affect the fan at this point. Fan cooled heat exchanger Baton Rouge Louisiana.

Fan/light models expand the wall switch options

When wiring a fan/light model, you will need a separate circuit for the light switch as you cannot supply line voltage to the red wires. Fan cooled heat exchanger Baton Rouge Louisiana.

To wire a fan/light, you can use two separate signal pole switches, and run separate switches for the light kit and the signal loop for the fan motor. Fan cooled heat exchanger Baton Rouge Louisiana.

Or, if you prefer, you can use a single pole over single pole switch.

Breaking the common tab on the line side of the switch.

Use one switch to control power to the light and use the other switch to control the signal loop for the fan motor. Fan cooled heat exchanger Baton Rouge Louisiana.

If you would like to use one switch to have the light come on when you turn the fan on or to its boost mode.

You can use a double-pole, single throw switch. Use one pole to control power to the light kit .

And use the other pole to connect the wires to the the signal loop for the fan motor. Fan cooled heat exchanger Baton Rouge Louisiana.
