MVHR System Enhancements

• 

  There are a number of ways in which you can gain maximum return on your MVHR investment which will give you added cooling and heating benefits. Please note however, they may not be suitable for every application but our design engineers will be happy to assess your requirements.

  ComfoCool Q600 Air Tempering Unit (Only for use with the ComfoAir Q600)

  The ComfoCool air tempering unit used in conjuction with the ComfoAir Q helps to reduce humidity along with the intake air temperature which in turn impacts on the internal environment and comfort levels. It can be easily integrated into your ventilation system to provide filtered fresh supply air whilst consuming a low amount of energy and at low noise levels.

  Cooling is automatically activated by a user defined comfort temperature in combination with monitoring both intake air and internal air temperatures. It is also equipped with a compression cooling system, as is used in refrigerators to reduce the temperature, in this case of the incoming supply of filtered air. The unit differs from traditional air-conditioning by using the air performance of its sister MVHR system to deliver the available cooling power.

  Ground-to-air Heat Exchanger

  When used in combination with your MVHR, the ground-to-air heat exchanger takes advantage of the natural geo-thermal temperature of the earth 1.5-2m below the ground generally a constant 8-12°C all year round. Download here to view a list of the component parts.

  Fresh ventilated air is drawn in through the polypropylene anti-microbial coated underground pipe which pre-cools the air in summer or pre-heats it in winter. This ensures that the air coming into your MVHR system is never below 5°C even with temperatures as low as -15°C. The system works in reverse during the summer months. The system claims a Coefficient of Performance (COP) of around 50 – this compares to a COP on ground source heat pumps of around 3-4). Not only is the system low maintenance it can reduce your carbon footprint. The system is popular with self build home owners looking to work towards or attain Passive House accreditation.

  Pre & Post Heat Options

  In some instances there may be an opportunity to increase the air temperature coming into your property during cold spells to ensure that balanced ventilation can be achieved, and you can also add further heat to achieve a preferred "comfort" temperature. Pre- and post-heaters are usually fitted in-line in the ducting. Unless you are building to an accredited Passive House standard, it is not recommended that you rely on this as your main source of heating as only limited heat is transferable by air. The distribution of heat cannot be guaranteed as it is reliant on superior levels of insulation and the air flow rates and length of duct runs to various parts of the property. It is important for you to note that ADM Systems specialise only in ventilation systems and are not qualified heating engineers. We strongly recommend you speak with your appointed heating engineers in order to determine what system is best for your property.

  Enthalpy Exchanger (helps with low humidity issues)

  Homes which have very low humidity can cause issues for occupants such as dry skin and chapped lips. This unique easy to clean, polymer exchanger is designed to optimise indoor air comfort by reintroducing humidity back into the property.

  The Enthalpy Exchanger also negates the need for a condensate drain within the MVHR unit itself, and can be retrofitted in some models at a later date if required.
