Essential HVAC Guide

Individuals regularly talk about getting some type of temperature control contained with their reverse cycle ducted air conditioning system. What exactly are the various types of air-conditioning temperature control and how do they operate? We shall examine how they operate under and the common sorts of air-conditioning temperature control systems.

Fundamental Ac Control

The fundamental control which is included with your reverse cycle air-conditioning system includes a thermostat that reads the air conditioners temperature. Typically this temperature is read either from your control itself or more usually inside the return air carton of the unit that sits inside the roof space.

It’s occasionally not a precise representation of the temperature in the room, if the temperature is read inside the return air carton. The room itself may be rather chilly but by time the atmosphere is recirculated to the return air carton it may have warmed up significantly which means the air conditioner will keep running (e.g. the control in the living room is establish to 22 levels but once the atmosphere reaches the return air carton it’s heated back up to 30 levels, which in turn causes the air conditioner to keep running).

In this scenario, the unit will keep running even though individuals have become cold. You’ll find yet two choices to counteract this. Firstly, raising the temperature of the controls will cause the unit to cycle away faster. It has to be recalled the temperature set on the control is typically not precise, instead it operates as a scale (i.e. if you establish to 22 measures, it does not automatically mean the room will cool to 22 degrees).

Second, a number of people set a ducted frozen steady in their own hall near the return air grille. This steady as it name indicates is constantly on. This permits the conditioned atmosphere to return readily back up to the return air carton of the unit, which helps the unit cycle away. In this example if you’re running only your bedrooms that were all a long way from the return atmosphere, the atmosphere from your rooms would heat up too much before getting back to the return atmosphere. The frozen steady yet would bleed air straight back into the grille that will make the unit cycle away and finally save money in running costs.

VAV Air-Conditioning Control

VAV stands for Variable Air Volume system. This can be where the zone motors for your own reverse cycle ducted air conditioning system permit some temperature control to the rooms you’re in.

A zone is essentially some blades that shut the ductwork if you need to quit the atmosphere to some room. As an example, if you turn off your bedroom, the blades shut limiting the air flow from continuing down the ductwork and into your bedroom. Moreover, when you need atmosphere, the blades completely open and atmosphere begins to flow out the diffuser and into your room.

VAV systems work otherwise yet. Instead of the blades just opening or shutting, they’re able to always fix what percent they can be open. This continuous adjustment allows you to control the quantity of airflow you go into a room which finally controls the temperature of the room.

By way of example, if your room is approximately 30 degrees and you establish your VAV control (located in the real room) to 22 levels, the air would run in attempting to cool the room. Once the temperature in the room got to around 22 degrees, the blades will begin to close to limit the airflow to keep that temperature. Just as the room temperature begins to rise above 22 degrees, the blades will open again to let more airflow in to bring it back to the 22 degrees. As a result the VAV system can keep the temperature in an area.
