Panasonic ventilation unit combining comfort and energy savings

Panasonic has added an efficient heat recovery ventilation unit for residential projects to its portfolio that improves air quality inside the home and maintains a healthy level of relative humidity. It is part of Panasonic’s ongoing commitment to developing products offering greater energy efficiencies, that contribute to the delivery of NZEB buildings.

Today’s new homes are being constructed to high standards with almost airtight walls, windows and doors, and no structure gaps. While this minimises uncontrolled ventilation and draughts, and provides increased energy efficiency, homes still need to have good-quality indoor air and an efficient ventilation system. Panasonic’s new PAW-A2W-VENTA unit is the answer.

This new heat recovery ventilation unit is designed not only to provide good indoor air quality, but also to recover heat that would otherwise be lost through ventilation. This leads to lower heating requirements and helps meet the Energy Performance of Buildings Directive (EPBD), making it ideal for low energy homes.

Space-saving solutions

Designed for areas up to approximately 140sq m, the compact unit can be installed with Panasonic Aquarea air-to-water heat pumps to provide an ideal solution for heating, cooling, ventilation and DHW. As it saves space by combining solutions, it is ideal for homes with limited space.

Two models are available to ensure easy and neat installation – one offering the supplied air on the left side of the unit, and the other on the right side. It therefore suIts any installation requirement. Both feature a high energy efficiency rotary heat exchanger with EC technology fans, and these provide a moisture transfer function to minimise condensation in supply air during winter.

The new PAW-A2W-VENTA unit can be combined with the Aquarea all-in- one compact system, or it can be placed on top of a DHW square tank with either Aquarea mono- bloc or Aquarea bi-bloc. The ventilation system can also be conveniently placed on any wall using Panasonic’s wall brackets.

User friendly interface

In an ever-growing digital world, Panasonic recognises the need for convenience and simplicity, resulting in the ultimate user-friendly interface for the system. All settings and features of the PAW-A2W-VENTA are accessible via the easy-to-use control panel that is integrated into the front cover. The option to connect one or more external control panel is also available with up to 10 controls possible in one system.

Other benefits of the ventilation unit controller include a weekly schedule for fan and temperature setpoints throughout the week, as well as a useful menu for filter maintenance that clearly displays the remaining filter time.

If combined with the Aquarea heat pump, the two systems can be managed with just one controller. The system has a host of useful features such as a manual and an auto mode, or the ability to choose preferred settings from the pre-configured user modes.

How does it work?

Designed to provide filtered fresh air into the home, the highly-efficient ventilation system also maintains high thermal comfort. The process can be broken down into three sections: (1)The ventilation unit extracts air from wet areas (kitchens, bathrooms, etc); (2)Fresh outdoor air is drawn into the unit via the pipe system. Here, 84% of the heat from the extracted air is transferred to the supplied air via a heat exchanger; (3)Fresh air is then supplied back to dry areas of the house (living room, bedrooms, etc);
