Essential HVAC Guide – Air conditioning unit Control Systems

People often talk about getting some form of temperature control included their own reverse cycle ducted chilling system. So what always be different forms of conditioning temperature control and how do they work? We look at the common types of air conditioning temperature control systems and how they work below.

Basic Air Conditioning Controller

The basic controller which comes with your reverse cycle air conditioning system along with a thermostat that reads the air conditioning units temperature. Usually this is actually read either from the controller itself or typically inside the return air box of your unit that sits within the roof position. air conditioning

If the temperature is read the particular return air box, individuals sometimes no accurate representation of the temperature in the room. The area itself might be quite cold but from time the air is recirculated to the return air box it might have started significantly therefore the hvac will keep running (e.g. the controller in the living room is set to 22 degrees the moment the air reaches the return air box the keyboard heated back up to 30 degrees, which usually turn causes the air conditioner to keep running).

In this situation, the unit will keep running despite the fact that people growing cold. Lucrative however two options to counteract this process. Firstly, increasing the temperature of the controls causes the unit to cycle off more speedily. It needs being remembered that the temperature set on the controller is generally not accurate, instead operates as a scale (i.e. if you determine to 22 degrees, it does not necessarily mean the room will cool to 22 degrees).

Secondly, make use of them put a ducted fixed constant inside their hallway around the return air grille. This constant merely because name suggests is always on. Up-to-date as new information the conditioned air another easily save to the return air box with the unit, assists the unit cycle out of. In this instance if you were running just your bedrooms that were all a good from the return air, the air from the rooms would heat up too much before taking back to the return wind. The fixed constant however would bleed air directly back up the grille which is going to make the unit cycle off and ultimately save you money in running costs.

VAV Air conditioning Controller

VAV is Variable Air Volume course of action. This is for the zone motors for your reverse cycle ducted hvac system allow some temperature control towards the rooms you are in.

A zone is basically a associated with blades that close the ductwork you actually want cease the air to an area. For instance, if you turn off your bedroom, the blades close restricting the snap from proceeding down the ductwork and into your bedroom. Likewise, when you want air, the blades fully open and air starts to flow the diffuser and into room in your home.

VAV systems work differently however. Rather than the blades simply opening or closing, they can constantly adjust what percentage they are open. This constant adjustment lets you control is going to be of airflow you enter into a room which ultimately controls the temperature on the room.

For example, if your room is around 30 degrees and you add your VAV controller (located in regularly room) to 22 degrees, the air would rush in doing cool the area. Once the temperature globe room got to around 22 degrees, the blades will start to close to restrict the flow of air to maintain that temperatures. As soon being the room temperature starts to increase above 22 degrees, the blades will open again to let more airflow in generate it for you to the 22 degrees. Performing this the VAV system can maintain temperature in the room.
