Essential HVAC Guide – Air Conditioning Control Systems

Persons often speak about getting some kind of temperature control included with their reverse cycle ducted air conditioner system. So what are different varieties of air conditioning temperature control and how do they work? We will look at the most popular types of air conditioning temperature control systems and how they work below. aircon review

Basic Air-con Control

The basic controller that accompany your reverse cycle ac system comes with a thermostat that reads the air conditioners temperature. Generally this temperature is read either from the control mechanism itself or more commonly inside the return air box of the device that sits inside the roof space. 

In the event the heat is read inside the return air box, it is sometimes not an accurate representation of the temperature in the room. The room itself may be quite cold but by the time the air is recirculated to the return air container it may have heated up up significantly which means the air conditioner will keep running (e. g. the controller in the living room is arranged to 22 degrees but as soon as the air reaches the return air box it has heated back up to 30 degrees, which causes the air moisturizing hair product to keep running).

Found in this situation, the product will keep running even though people are becoming cold. There are however two options to fight this. Firstly, increasing the temperature of the handles will cause the product to cycle off faster. It requires to be recalled that the temperature arranged on the controller is usually not accurate, instead it works as a scale (i. e. if you set to twenty-two degrees, it does not necessarily mean the room will cool to twenty-two degrees).

Secondly, some individuals put a ducted fixed frequent in their hallway nearby the return air grille. This kind of frequent as it name suggests is always on. This allows the trained air to return easily look out onto the return air box of the unit, which helps the unit cycle off. In this case if you were running just your bed rooms that were all a considerable ways from the return air, the air from the rooms would heat up too much before getting back to the go back air. The fixed regular however would bleed air directly back into the grille which will make the unit cycle off and finally save money in running costs.

VAV Air Conditioning Controller

VAV means Variable Air Quantity system. This is when the area motors for your change cycle ducted air training system allow some temperatures control to the rooms you are in.

A zone is basically several blades that close the ductwork if you wish to stop the environment to a room. For instance, if you turn off your bedroom, the blades close limiting the air flow from proceeding down the duct work and with your bedroom. Furthermore, when you want air, the blades fully start and air starts to flow out the divulguer and with your room.

VAV systems work differently however. Instead of the rotor blades simply opening or shutting, they can constantly adapt what percentage they are open. This regular realignment allows you to control the amount of airflow you get into a room which in the end controls the temperatures of the room.

Pertaining to example, if your room is around 30 levels and you set your VAV controller (located in the actual room) to 22 degrees, the air would rush in striving to cool the space. When the temperature in the room have got to around twenty two degrees, the blades will learn to near restrict the airflow to keep that temp. As soon as the room temperature starts to increase above 22 levels, the blades will open up again to leave more airflow in to take it back to the twenty-two degrees. By doing this the VAV system can maintain the temperature in a room.

The VAV method is one of the most basic varieties of air conditioning temperature control. This can be a cheap way to add temperature control to simply a few rooms (say your master suite, office and living room for instance).

This system is not to be confused with VRV. VRV air bodies systems use multiple wall membrane splits (head units) jogging of a single large outdoor compressor.
