General Information
2.11 Cooling CTC EcoComfort
CTC EcoComfort is an accessory which utilises the cool temperatures
of the bore hole to create a cool indoor climate in summer. The extent to
which you can cool a property depends on several factors, such as the
rock temperature available for the case in point, the size of the house, the
capacity of the fan convectors, the living area layout, etc.
NOTE: Remember to insulate pipes and connections against condensation.
Separate heating/radiator system and cooling system
(fan convector)
EcoZenith simultaneously manages a radiator system for heating and a
separate system for cooling. This can be relevant if you want to cool a part
of a property using e.g. a fan convector at the same time as need to heat
another part.
Desired room temperature
The desired room temperature is set on the EcoZenith display. The water
mix is automatically adjusted to achieve the right temperature for the amount
of cooling needed (room sensor deviation). The greater the deviation, the
colder the water fed into the system. Depending on the system in question,
temperatures are not permitted to become too cold (as this can result in
damage due to damp).
NOTE: For cooling it is recommended that the room temperature be set a
few degrees higher than the set temperature for heating operation. Given
that the room temperature tends to increase as the outdoor temperature
increases, the cooling function will cut in.
Note too that cooling capacity depends, among other things, on bore hole
temperature, bore hole length, flows and fan convector capacity, and will
vary during the warm part of the year.
See CTC EcoComfort manual for more information.
