Different Air Conditioning Temperature Control Systems

Buyers of ducted reverse cycle air conditioning systems want to use some temperature control unit. There are several options for this purpose. The temperature controller helps control your air conditioner maintains in the rooms. Learn more about these systems and their functions. The following information provides details of some common AC temperature control systems.

Basic Controller

It generally comes standard with a reverse cycle ducted AC system. It is present in a thermostat and can read the AC temperature. The controller provides the temperature data, or it is obtained from the unit’s return air box found in the roof space. The temperature obtained from the inside of the return air box may not provide accurate room temperature data. The room may be cold, but the unit’s return air box may have warmed when air is recirculated. It means the AC will continue to run (for example, the controller is set at 22 degrees in a room, but after the air has reached the air box, its temperature may have reached 30 degrees, forcing the air conditioning unit to keep running unnecessarily). It means that residents will start feeling cold even though the air conditioner is running at the set temperature. There are two ways to handle this issue. First, the temperature in control can be increased to cycle off faster. Keep in mind that the temperature you set in the controller will not be accurate. For example, if you set it at 22 degrees, the room will not have an exact 22 degrees temperature. Some people use a device to solve this problem of the air conditioning unit. They place a fixed ducted constant in the hallway close to the air return grille. This device is always on, allowing the conditioned air to return to the unit’s return air box easily, making it easier to cycle off. If your bedroom is far away from the returning air, the room air will heat up very high before it can get back to the returning air. However, the air from the constant would bleed directly into the grille, making the system cycle off. Your operating cost will come down with this constant process.

VAV AC Controller

Variable Air Volume or VAV is the setup where zone motors used in the ducted reverse cycle AC system allow temperature control for the selected room. In the case of a zone, multiple blades move together to close the ductwork when you want to restrict air entry into a room. For example, when you switch off your bedroom AC system, the blades will close, stopping the air from going to the ductwork and reaching your bedroom. Similarly, the blades will open fully when you need air, and the air will start flowing into the diffuser and your room. A VAV system works differently in the air conditioning system. In place of blades just closing or opening, it continuously adjusts the percentage of its opening. This continuous adjustment allows you to control how much air you receive into a room. This method is used to control the room temperature accurately. Suppose your room has a temperature of 30 degrees, and the VAV controller (installed in the target room) is set at 22 degrees. Now the air will come rushing in to cool the room’s interior. Once the room temperature reaches 22 degrees, the system closes the blades to stop the airflow and maintain that temperature. When the temperature in the room starts increasing again and goes above 22 degrees, these blades will open to allow more airflow and get the room temperature back to 22 degrees. The VAV system can maintain the room temperature by continuously adjusting this way. The VAV systems remain the most basic temperature control systems for the ACS. They are an economical option to add a temperature control system to an AC unit used only for a few rooms (for example, your master bedroom, living room and office). Do not confuse this VAV system with VRV. The VRV AC system uses several walls splits or head units running out of one large outdoor compressor.

Total AC Temperature Control System

Fully ducted AC temperature control works are similar to a VAV system. The controller placed in each room reads the temperature. This data is used to close or open the blades, allowing the correct airflow and cool or heat the interior. The difference is that a full temperature control system is used to control the temperature of the whole house. It is not limited to a few rooms only. A total temperature-controlled AC system allows every individual to set the temperature based on their comfort level. They can set the preferred temperature for their living area. These temperature-controlled AC systems are more economical to run than standard systems because of their energy-saving features. It is possible because the controller switches off the unit once the room temperature reaches the set level. It allows the system to cycle off. It will save you money in the AC operating costs.

Why Select an Air Conditioning System with Temperature Control?

Every person can set the unit’s temperature at their desired level with the help of an AC temperature control unit. Everyone does not feel comfortable at the same temperature. People want to set the room temperature to their preferred setting. Some other factors also determine what should be the room temperature. For example, heat from people, devices, clothes, furniture and other things present in the room affect the room temperature. The clothes residents are wearing and which side of the sunrises are other factors. Temperature control systems solve all such issues because they allow each individual to set the room temperature based on their comfort level and indoor environmental conditions. One thing these systems cannot do is provide separate heating and cooling operations. If an air conditioning system is set for cooling, it will only cool the rooms. If a person in one room wants heating and another in another room wants to cool, the AC system cannot handle these two different temperature requirements.
