ComfoFond-L ECO

 

The Zehnder ComfoFond-L ECO subsoil heat exchanger is designed to complement Zehnder heat recovery units.

 

How does a sub-soil heat exchanger work?

The sub-soil heat exchanger uses the almost constant annual temperature of the earth at a depth of 1/1.5m. This store of energy stays at a temperature of 8 – 12 oC all year round and can be utilised to pre-cool or pre-heat incoming supply of air in summer and winter months.

When connected to a Zehnder ComfoAir 350/550 Luxe Systems it increases the comfort of the supply air to the dwelling throughout the year, even when the temperature fails below zero.  This can help improve the efficiency of the heat recovery units as the incoming air requires less energy to meet the desired comfort temperature.  By saving energy and providing an optimised indoor climate, benefits are felt by the building the homeowner and the environment.

energy efficiency

Features and Benefits:

  • Tempered supply air throughout the year

  • Operates automatically thanks to its integrated temperature sensor

  • Ideal for use in High-water table and extremely effective in water bearing sand/gravel and granite soil types

  • Exceptional energy efficiency due to utilisation of renewable energy from the ground

  • The system is low maintenance and all serviceable parts are easily accessible

  • Frost-free permanent operation, even at external temperatures of less than -25 oC

  • Zehnder ComfoFond-L Eco provides a closed loop system which offers improved hygiene over open loop versions

  • The closed loop system offered by Zehnder ComfoFond-L Eco delivers lower air resistance than an open loop system leading to lower running costs and enhanced efficiency

  • Design and supply from one manufacturer ensures compatibility and ease of integration

 
 

Zehnder ComfoCool 350

Zehnder ComfoCool is equipped with a compression cooling system, as is used in refrigerators. This process releases energy that is discharged in the air exhausted from the dwelling. The result is that energy is transferred from the supply air (which becomes cooler and drier as a result) to the exhaust air (which heats up as a result).

The combination of Zehnder ComfoCool and MVHR cools more efficiently, as the heat recovery unit then behaves more like a ‘cold recovery unit’ in warm weather. Warm fresh air is pre-cooled by the heat recovery unit and then cooled further by Zehnder ComfoCool.

Features and Benefits:

  • Temperature control of supply air volume 150 to 350 m³/h

  • Suitable for ComfoAir 350 Luxe

  • Low noise emissions

  • Constant supply air temperature

  • Supplies fresh, cool air and dehumidification in conjunction with controlled home ventilation

  • Low energy consumption

  • Control via ComfoControl Luxe control unit

Enthalpy Exchanger

Enthalpy Exchanger

 

 

The Zehnder Enthalpy Exchanger recovers both the thermal and the latent energy from the stale air extracted from wet rooms around the home. This additional energy, which would otherwise have been lost, is transferred into the incoming fresh air stream before being supplied to habitable rooms.

 

Choosing the enthalpy exchanger, rather than the standard heat exchanger, means that the unit becomes an Energy Recovery Ventilation (ERV) system, as opposed to solely a Heat Recovery Ventilation (HRV) system.

Features and Benefits:

  • Hygienic plate heat exchanger

  • No moving parts

  • Long-term prevention of odour and microbe transmission

  • Enthalpy exchanger can be retrofitted at any time

  • No additional current draw

  • Available for unit Zehnder ComfoAir G90-300, G91/300, 350, 500 and 550

 

MVHR Controls
