The Modul-AIR BLUE

The Modul-AIR Blue Exhaust Air Heat Pump (EAHP) and optional Climate Control Module (CCM) provides balanced mechanical ventilation with heat recovery (MVHR), domestic hot water (DHW), heating via radiators, underfloor (UFH) or fan coils & cooling.

This solution is best suited for new build flat developments. It uses the waste heat from the extract ventilation through a heat pump cycle to provide the heating and hot water for the dwelling. When fitted with the optional CCM the supply air to the habitable space is pre-heated to increase the occupants comfort level and thus reducing the load on the radiators or underfloor heating in the dwelling. In addition to this in the summer months the heat pump cycle can reverse and provide up to 3kW of cooling via the CCM supply ductwork & an additional fan coil. With regulations continuing to develop, a typical dwellings heating load is reducing while the requirement for more renewable heat sources is increasing. In the UK the introduction of Part O overheating guidance, has provided guidance to developers on limiting the overheating risk in new build residential dwellings. The Modul-AIR Blue can achieve the requirements set out in the TM59 guidance, in even the more challenging buildings.

Certain measures must be considered when designing the store room for the Modul-AIR Blue & CCM. Firstly, the Modul-AIR must be positioned on a suitably structured floor. It cannot be fitted against a wall adjoining a bedroom.

Clearance distances on both the heat pump and cylinder must be adhered to in order to provide suitable maintenance access for the system. Careful consideration must be taken to ensure these clearance distances aren’t restricted by standard door head heights.

The Modul-AIR Blue & Climate Control work seamlessly with either radiators, UFH or fan coils. As with all low temperature heat pumps there are a number of design parameters that differ with high temperature conventional systems.

Radiators

Following an accurate heat loss calculation suitably sized steel, aluminium or fan coil radiators should be selected on the maximum design parameters of 45/40 flow & return. TRV’s should not be fitted on the radiators and the minimum pipe work feeding the radiators should be 15mm or greater. The system should be designed to aid the balancing, such as reverse return circuits. Assuming the dwelling is less than 100m2 (IE) or 150m2 (UK) one heating zone and corresponding thermostat should be fitted. For dwellings greater than 100m2 (IE) the bedroom areas should be zoned together. Modul-AIR thermostats must be used to control each zone.

Underfloor Heating

Underfloor heating must always be fitted in a screed or cement based system. Pipe centres should be no greater than 150mm if using 16mm pipe or 100mm centres if using 12mm pipe. As with radiators control if the dwelling is less than 100m2 (IE) or 150m2 (UK) one heating zone and corresponding thermostat should be fitted. For dwellings greater than 100m2 (IE) the bedroom areas should be zoned together. Modul-AIR thermostats must be used to control each zone.

The Modul-AIR Blue & Climate Control work seamlessly with either radiators, UFH or fan coils. As with all low temperature heat pumps there are a number of design parameters that differ with high temperature conventional systems.

Cooling

There is a maximum cooling capacity possible of up to 3kW. The capacity is dependent on the ducting arrangement and  emitter chosen. Cooling can be done my various means. When cooling via UFH the machine keeps the supply temperature above condensation point (18C). Its optional to have cooling via fan coils set to 12C, where condensation will need to be manged.

Modul-AIR Blue & CCM (MVHR)

• Utilising only the CCM via the duct network will supply approx. 1kW into all habitable spaces (airflow dependent).
• Utilising both the CCM and the UFH will supply 3kW into the desired rooms, and is controlled via the same thermostat.
• Utilising both the CCM and the existing or additional fan coil radiator will supply 3kW into the desired rooms, and is controlled via the same thermostat.

Modul-AIR Blue (cMEV)

• Utilising the UFH or a fan coil radiator will supply 3kW (emitter dependent)
