What are Single Room Heat Recovery Ventilation Systems (SRHRV) and their Applications?

The technology behind heat recovery and ventilation systems has come a long way from the old days. To see how advanced the modern mechanical ventilation and heat recovery systems have progressed, all we need to do is compare their efficiency rates with older models.

That’s not all though, because the price tags have also come down significantly, meaning that a modern heat recovery and ventilation system is significantly more energy efficient, capable, and cheaper than its predecessors. Then there is also the flexibility that modern engineering has allowed for, making something as useful as the single room heat recovery ventilation system (SRHRV) possible.

What is a Single Room Heat Recovery Ventilation System (SRHRV)?

The single room heat recovery ventilation system (SRHRV) is also known as the single room mechanical ventilation and heat recovery (SRMVHR) system, so don’t be confused by the abbreviations and the long name as they both mean the same thing. It’s a much smaller and more affordable version of the regular MVHR system.

These are through the wall, heat recovery and ventilation units, designed exclusively for single room installations. Just like the big MVHR systems we see installed in apartment buildings and individual houses, single room MVHR units:

·       Extract moisture and force out stale indoor air to keep bad smells, damp, and mould at bay.

·       Replace the stale air with fresh air from the outside to facilitate constant ventilation.

·       Minimise loss of heat during ventilation by extracting heat from the air being pushed out and transferring it onto the fresh air replacing it.

·       Filter air to keep all external air pollutants out of the indoor space.

Not All Rooms are Equal Though

As we can see, the functions of a single room ventilation and heat recovery unit are identical to regular MVHR systems, but on a smaller scale. Now, this is where things can get a little complicated because not all single rooms are of the same size. A single room in a country house can be bigger than the average city apartment.

Therefore, it’s important to make sure the single room MVHR system you buy has the capacity to keep the intended room ventilated. For more information about heat recovery and ventilation systems for single rooms and the capacity you should be looking for in your own unit, visit BPC.ie.

What are the Applications of a SRMVHR System?

There are several scenarios where the single room MVHR system presents itself as a viable solution. Perhaps the architecture of the main building cannot support a full installation, or perhaps there just isn’t enough space to accommodate a full-sized heat recovery and ventilation unit. Either way, single room ventilation and heat recovery systems are perfect for any walled space where a full-sized installation is not possible. This would include single room apartments and even just a single room in a larger apartment.

SRMVHR units may have single room in the name itself, but you do not need to worry about the bathroom. All single room MVHR systems include ventilation for the bathroom as well. However, that is where you need to be careful with the unit’s total capacity. It must be enough to cover the total area, including the bathroom.
