Zone-based air conditioning, also known as zoning, is an operation and regulation concept that is highly effective. Enabled by multi-zone heat pumps (of the “Split” type), zoning allows for the distribution of cool air in each room of a residence.
Typically, the various “zones” or rooms in a house have their unique characteristics in terms of conductivity and heat response, referred to as their thermal load. Factors such as exposure to sunlight, insulation quality, windows, and occupancy can differ significantly. Hence, the relevance of managing their comfort level in a targeted manner, avoiding unnecessary cooling of rooms that do not require it. This is what zone-based air conditioning facilitates.
A heat pump for zone-based cooling
With a standard central heat pump, cooling is performed without real distinction from one room to another. Connected to the forced air system, it tempers all areas, but with the same cooling input. The temperature is set by a central thermostat. It’s possible to adjust the cooling by playing with the opening of air vents on the floor.
To address this issue, variable air circulation systems are available. Through a set of dampers in the ductwork, they can automatically adjust the amount of cool air delivered to each zone based on the thermostats located there.
Even if the residence does not already have a duct system, zone-based cooling with a heat pump can be achieved through a single indoor unit. Ideally, this unit is placed in a central location. There, ventilation grilles are installed to capture air and circulate it to other zones via concealed ducts in the ceiling. Airflow into the rooms can be controlled by a thermostatic manager.
“Multi-split”: the ultimate comfort zone
For optimal comfort and control, multi-zone heat pump systems (with the outdoor unit connected to several indoor units) are recommended. Wall-mounted units can be independently controlled by thermostats in each zone.
Adaptable, discreet, economical, and more ecological, zone-based air conditioning systems offer various options. Consult GestionAir experts to find out what suits your needs.
