The new Susurro, a ceiling mounted heat recovery unit from Airflow Developments, has been designed to provide continuous decentralised ventilation for both office and educational environments. Featuring a new generation of efficient, energy saving and ultra-quiet technologies, architects can be assured that the units meet all the necessary regulations, and provide a fresh and healthy indoor air quality for the occupants.

Susurro in a seminar roomA multitude of key features makes Susurro a high performance ventilation option for new and existing offices and school buildings. With an aluminium cross counter flow heat exchanger, the unit recovers up to 90% of otherwise wasted heat. In accordance with the ErP Ecodesign Directive, Susurro features a 100% summer bypass facility to prevent heat recovery from taking place in hot weather – reducing the risk of overheating.

Its unique capillary tube system at the air outlet ensures that fresh air is supplied into the room near the ceiling. This supply air then mixes with the ambient air, before slowly descending into the room, avoiding any uncomfortable draughts for building occupants.

1_0010_Background copySusurro is the ideal option for office and educational environments, helping to improve air quality and with a virtually inaudible noise level of just 35 dB(A) at nominal air flow, the units can contribute positively to an environment that aids concentration and productivity. All Susurro units comply to both BB101 and BB93 guidelines for educational premises.

John Kelly, Marketing Manager at Airflow Developments said: “Our new Susurro heat recovery unit is a testament to our knowledge and capability within the complex field of ventilation. It delivers precisely what is needed: a highly efficient, low energy, low noise heat recovery unit that can make a positive difference to the wellbeing of office workers and students alike.”

1_0004_Background copy (1)No air ducts are required and units are suitable for offices, boardrooms and educational facilities. For existing buildings, there is no need to design a detailed ventilation system, as it is simply mounted on the wall. With a digital touch screen controller and offering automated control to optimise performance – Susurro maximises energy efficiency and minimises heat losses with minimal input from the building manager.

Susurro is available with a three-year warranty, and energy efficient EC motors. The unit is available in two ranges: standard and design. With air flow rates of 400, 700 and 1000 m3/h, units will provide an ambient temperature range of +5°C up to 40°C.

How to provide on-demand commercial ventilation without the upfront cost

When designing a new ventilation system for your commercial premises, one of the many aspects that need to be considered is the ongoing running costs of the system. Whilst a BMS (Building Management System~) offer the building manager the ability to control the building’s ventilation and remotely monitor the system’s performance, they can add significant cost to the ventilation system’s initial outlay. There is, however, an alternative that still grants the building manager and the occupants of the building demand-based ventilation without the large upfront cost of a BMS – a VAV System.

A Variable Air Volume (VAV) system can be used in conjunction with market leading commercial MVHR systems such as Airflow’s Duplexvent range. They enable the occupants and the building manager the ability to adjust the level of ventilation to different rooms or zones of the building based on localised changes in demand.

With air pollution making the news for the wrong reasons coupled with a drive towards increased energy efficiency it is key that you have a ventilation system that gives the occupants a healthy and comfortable indoor air environment whilst remaining energy efficient and cost effective.

Airflow - VAV DamperIntuitive VAV Dampers work by communicating directly with the MVHR system to adjust the system’s ventilation swiftly based on changes in ventilation demand. When combined with humidity or CO2 sensors, a VAV system can automatically respond to changes in room or zonal occupancy, independent to the other areas of the building.

This differs from many centralised MVHR systems that don’t use demand-based control. With these systems, the ventilation rate remains the same in each room regardless of occupancy level. This leads to one of two things:

  • Either the room is being unnecessarily over-ventilated, which is wasting energy and increases ongoing energy bills of the premises, or
  • Busy areas are not receiving enough ventilation and as a result, those in the room are breathing unhealthy air that can affect concentration and productivity levels and in worse cases can worsen respiratory issues. Furthermore, there is the chance that damp and mould can develop within the room, which as well as affecting the health of those inside the area, can damage the fabric of the building itself.

Whilst this functionality can be found within a quality BMS they can add significant cost to the development. By using a VAV system, you gain the level of control and responsive ventilation you’d normally receive through a BMS without the initial outlay that goes with it. With spending being increasingly held to account, why would you pay more when you can get a system that offers the same level of performance for less?

Low income families are typically more affected by air pollution with children most at risk. The UK currently has over 40,000 deaths a year linked to poor air quality costs the economy billions a year. With indoor air pollution often 50% worse than outdoors and can contain up to 900 different pollutants it is imperative that a suitable system is installed to improve the health of the occupants as well as protecting the fabric of the home itself.

Mechanical Ventilation with Heat Recovery (MVHR) is the process of continually preheating filtered, incoming fresh air from outside by warming it with the outgoing waste air which is created by kitchens, bathrooms, utility rooms etc. Once the warmth is transferred, the now warm, clean air is the supplied to the living areas such as living rooms and bedrooms.

The following example will show the cost benefit of having a MVHR system installed in the property. This example assumes that both properties are 300m2 in size.

House A House B
Uses extract and trickle vents to ventilate the property. It has 2 air changes an hour and uses gas heating to warm the property Uses an MVHR unit with 71%* heat recovery. It has an air change rate of 320m3/hr (89 l/sec), assuming no infiltration and uses gas heating to warm the property
Heat loss from infiltration at 2 ach 14,164 kWh per year at a cost of £0.0359 per kWh = £508.49 per year Heat loss due to ventilation at 320m3/hr at 7677kWh with 71% thermal efficiency = 2226 kWh. With a cost of £0.0359 per kWh = £79.92 per year
Cost of running a bathroom and kitchen fan operating at 1 hour per day at 0.05kW = £2.08 per year MVHR with two fans running, operating 24 hours a day at 693 kWh = £104.70 per year
Total ventilation energy cost = £510.57 per year Total ventilation energy cost = £184.62 per year

Additional saving with 80% thermal efficiency = £16.54

Additional saving with 90% thermal efficiency = £34.90

All new Airflow domestic MVHR units have a thermal efficiency of 90% or greater so you stand to see up to a £355 per year reduction in your energy bills.**

*Domestic Building Services Compliance Guide Section 8 specifies a minimum thermal efficiency of 70%

**assuming a kWh price of £0.0359

An ideal MVHR system to be used in social housing settings is the Adroit

DV96-Adroit-_insideAirflow Adroit MVHR units can be set up during the commissioning process to limit the tenants’ access to the control system. This removes the issue of tenants changing the ventilation rates for the property as well as them switching the unit off, guaranteeing effective ventilation always takes place within the property; protecting the health of both property and tenants. Your tenants, however, will still be able to tailor their ventilation around their daily routine through selecting the relevant ventilation profile to suit their needs.

As landlords, you would be able to remotely monitor the performance of the unit and be notified of when maintenance, such as changing the air filters, is required and in turn prolong the lifecycle of your Adroit unit.

Furthermore, in our Adroit DV50 and DV80 models, you can have these installed above the entrance to the property, so maintenance can be undertaken to the unit without disturbing the tenant.

Airflow is proud to announce that we have introduced a new outdoor line to supplement our hugely successful Duplexvent Rotary MVHR range: the Duplexvent Rotary-N.

rotary-range-2016_06

The Duplexvent Rotary-N are all-purpose rooftop units that can improve the indoor air quality of various different commercial premises such as schools, restaurants, office blocks and warehouse whilst protecting the health of those working within the building as well as the fabric of the building itself. The compact design of the Rotary-N allows for a discrete installation and helps you to maintain an aesthetically pleasing design of the premises.

The Duplexvent Rotary-N helps to reduce the property’s energy costs thanks to its highly efficient rotary heat exchanger that can recover otherwise wasted heat energy and use it to pre-warm the incoming filtered, supply air. This means that the building’s heating isn’t warming the workplace as much as normal and in turn can reduce the energy bills of the property. This brand new range comes in 7 different models and is able to extract from 1550m3/hr (431 l/sec) to 16700m3/hr (4639 l/sec) with impressive sound levels from just 34dB(A).

Following on from the launch of our new Duplexvent Rotary-N range of commercial MVHR units, Airflow have also expanded our range of the existing Duplexvent Rotary range of compact, indoor commercial MVHR units with rotary heat exchangers.

With 7 units from you to choose from, there’ll be something to meet your ventilation needs. They are ideal for schools, offices and halls and will improve the quality of air circulating through property. The Rotary range can supply up to 16700m3/hr (4639 l/sec) from an unnoticeable 34dB(A).

All Duplexvent Rotary and Rotary-N units can filter out small airborne pollutants such as pollen or dust thanks to the unit’s ability to be fitted with G4, M5 or F7 air filters. This helps to maintain a healthy indoor air environment for those within the building. By maintaining a healthy indoor air environment, you protect from indoor air pollution, which research shows can affect productivity, concentration levels and in worst cases even cause severe health problems.

All units have 85% thermal efficiency thanks to the highly efficient rotary heat exchanger. Duplexvent Rotary units can be fitted with G4, M5 or F7 filters. The units adhere to the current ErP Ecodesign Directive requirements including the stricter, draft 2018 regulations. Furthermore, they help you achieve Passive House approval, thanks to their extremely low SFP values of less than 0.45W per m3/hr. Each model has T2 level insulation, an integrated web server and a sophisticated yet user friendly control system.
