How Does Zone Air Conditioning Work

To better understand how to deal with these problems let us first take a look at how zone control systems work. The concept of system zoning is similar to the HVAC systems you may have seen in large office buildings.

How does zone air conditioning work. The advantage of a multizone thermostat is that you can control the entire system from one location rather than having to go to each zone to adjust the thermostat. Older style traditional zoning requires a large common zone which remains open at all times to prevent air pressure build-up and damage to the ductwork. If the thermostat from a particular zone calls for heating or air conditioning the dampers in that zone will open to allow the air to flow into that area.

The zone calling for air will receive sufficient cooling for the associated space and any excess air will enter the bypass duct. These thermostats all connect to a central control panel in your home. Dampers are like large valves that you can turn on or off and control the flow of cooled air throughout your home.

If a second area needs heating or cooling the corresponding dampers are opened. Zoning is a simple product and concept. A thermostat is then installed in each individual zone.

A homeowner can lower or close off cooling power to locations that either require less cooling or which arent being used. Zone control systems are like traffic signals. Electronically controlled dampers placed strategically throughout your system of ducts form the basis of zone air conditioning.

In the photo above the three green lights are part of three zone dampers that control the flow of air to three separate zones. These dampers regulate the air flow into the separate zones. When an area needs more air from your heater or air conditioner the thermostat tells the damper to open up and let more air through.

If the temperature is too cold or too hot for your liking the thermostat will send a signal to the control panel to either bring on cool or warm air to that room or zone. Zoning provides the ability to only condition those rooms that need heating or cooling and does not allow conditioned air into those zones not requiring it. The dampers in the rest of the home remain closed.

Zone control divides a home into different regions zones with separate temperature controls that operate individually of each other for room-to-room air conditioning. The downside is initial cost typically ranging from 2000 to 3300 depending on the number of zones. Zoned air conditioning systems work differently depending on whether you have a duct or ductless AC.

The zone dampers also control the heat in wintertime. A colder evaporator coil is a less efficient evaporator coil. In a zoned system a single heating and air conditioning system is controlled by multiple thermostats in multiple zones.

In order to control the amount of cold air directed into each zone a zoned AC system uses electronic dampers. Thermostats read the air temperature in each room or zone of your house. Now youre sending cool air back into the return which makes your evaporator coil get colder.

Central HVAC systems are connected to a network of ducts leading from the cooling and heating systems into each room in the house terminating into air vents. How Does Zone Air Conditioning Work. A method for lowering home energy use that we recommend for houses that use a forced-air heating and cooling system a furnace and standard air conditioner or a heat pump is to outfit the HVAC system with a zone heating and cooling ie.

A thermostat is placed in each zone so that it can control the electronic dampers in your air ducts. Equipment called dampers are installed into the air ducts and wired to the central control unit. The sensors relay information to the thermostat and the thermostat controls whether each zone gets heat or air conditioning.

A zone control. How Does System Zoning Work. Ductless systems are automatically zoned while HVAC units that utilize ducts require additional work and zoned HVAC installation.

The common zone can occupy up to 25 or more of a home and you will pay to heat or cool it regardless of whether you use that area which creates wastage. Zoned heating and air conditioning should reduce total energy use and cost while precisely controlling temperature in each room or zone. The control panel regulates various temperatures in the house by activating dampers in the HVAC system.

Those are the points in favor of zoned HVAC. These dampers work like a valve system opening and closing the air flow to your zones. Zoning does this through a series of components the first being motorized dampers that open and close based on the demands of the zone thermostats.

The home is zoned but the HVAC system is not.
