To acquaint you with what have been considered as among the top cooling and heating systems in the market today, this article will review Panasonic’s ductless mini split solutions.

By tackling how these series of high-efficiency and high-performance units embody the high-degree of HVAC innovation, it is hoped that you will be able to properly discern and choose the right system for your home.

Total Home Comfort Solution, Efficient Heating, Ventilation, and Air Conditioning

A pioneering leader in comprehensive air conditioning systems, Panasonic has laid the groundwork for reinventing the way ductless systems are set up and made to work as an even more efficient and effective solution. We would not lack of systems to be used as examples here, but if there’s anything that best encapsulates this innovativeness and forward-thinking, it would be Panasonic’s most touted Total Home Comfort Solution.

Designed for whole-home cooling and heating, Total Home Comfort Solution is a fully integrated system that ingeniously combines high energy-efficient mini split units with powerful, customizable ventilation fan system that enables balanced, effective, precise, and efficient delivery and distribution of airflows throughout different rooms inside the house.

Total Home Comfort Solution makes use of Panasonic’s Exterios ductless split system, WhisperGreen™ Select ventilation fan, and WhisperComfort™ Select ventilation fan or Energy Recovery Ventilator (ERV). Together, these advanced technologies create a solution that turned out, arguably, as the “industry’s first complete total home comfort system.”

The whole Panasonic Total Home Comfort Solution operates simple but very efficient and effective. To better understand how it works, just imagine having a two-level house and you are using this system as a primary heating and cooling solution.

To understand how this works, let us say that your two-storey home has three or four rooms situated in the upper and lower levels, including a bathroom. To achieve whole-home cooling or heating, the first step is to install Panasonic’s Exterios ductless split system. Like any typical ductless system configuration, you will have to install the compressor unit in any suitable location outside the house. Unlike normal ductless mini split multiple-zone installation, Panasonic only requires one indoor unit or air handler, which you can conveniently install in the living room. For the rest of the rooms, you will have to install the WhisperGreen Select vent fans. As for the bathroom, you can install another of these WhisperGreen Select vent fan.

During cooling operation, for instance, the outdoor compressor unit delivers cool air which is properly circulated to the living room through the installed ductless air handler. The conditioned air is subsequently distributed to the different rooms through the WhisperGreen Select vent fan system, which is powerful enough to deliver the airflow (CFM output) needed to cool the specific spaces even at 0.25-inch static pressure. The same process happens if you are using the unit during Winter to heat your home.

As a supporting system designed to improve the indoor air quality, a WhisperGreen Select vent fan that is installed in the main bathroom works to control the growth of mold and mildew and eventually helps remove the polluted air inside the house.

Here are the sample components when installing the solution for a one-bedroom unit with a square footage of 500-1,000 square-feet and a two-bedroom unit with a size of 800-1,600 square-feet:

1-Bedroom (500-1,000 square-feet)
1 wall-mounted heat pump unit (indoor), 1 wall-mounted heat pump (outdoor), WhisperGreen Select™ 50-80-110 CFM distribution fan, WhisperGreen Select™ 50-80-110 CFM exhaust fan and motion sensor module.
2-bedroom (800-1,600 square-feet
1 wall-mounted heat pump unit (indoor), 1 wall-mounted heat pump unit (outdoor), WhisperGreen Select™ 110-130-150 CFM distribution fan and multi-speed module, WhisperGreen Select™ 50-80-110 CFM exhaust fan an motion sensor module, and WhisperComfort™ Energy Recovery Ventilator (ERV).

A Breath of Fresh Air

Indeed, the quality of air inside the home contributes to our experience or nonexperience of comfort. The United States’ Environmental Protection Agency warns that the air that we breathe inside our homes is 2 to 5 times more polluted than the air that we get outside. The agency also reports that on the average, 72% of our chemical exposure happens at home.

Coincidentally, some studies suggest that most Americans spend more amount of time indoors than outdoors. The risk is very real and Panasonic recognizes a need to step up and make its system a platform to protect health while providing temperature comfort.

“A lot more people don’t realize that the homes they live in are actually more polluted than the outdoor air they breathe between things such as outgassing from paints finishes to carpeting,” says Panasonic Regional Sales Manager Bret Gundersen. “You’re trapping a lot of pollutants in the home. If that air is allowed to stay inside the house and not exhausted out, you create bad indoor air quality,” he adds.

Typically, the buildup of stale, contaminated air is caused by the lack of fresh air that circulates inside the home. This is not in the very least surprising at all given that many homes today—driven by efforts to conserve energy—are designed as airtight than ever. This results to lack of fresh air indoors which aggravates the buildup of airborne pollutants that are responsible for a score of common health issues that occasionally afflict us and our families.

With indoor air pollution tagged by EPA as one of the top five environmental health risks, Panasonic—through its Total Home Comfort Solution—readily tackled the challenges head on. Through the Energy Recovery Ventilator (ERV), Panasonic introduces a way to achieve cleaner indoor air while the system is working to provide cooling or heating comfort. ERV works to replace the stale air indoors with a fresh air from outside while it is in the process of transferring the heat from the air that is exhausted to the incoming air.
