Description
Mini packaged u.VENT series controller
u.Vent series mini packaged controller is an economical kit for use in a small office and home devices that meets the basic needs of the system.
Advantages of using the mini packaged unit controller
- Complete control over the devices to further ensure compressor protection
- Reliability
- High efficiency of the device
- Making settings by connecting to mobile devices reduces the time to set up the mini packaged and eases maintenance.
One of the main characteristics of this solution is control. Application of u.Vent series mini packaged kit: small to medium commercial and residential units
Series mini packaged (u.VENT) components
Air Conditioning of Packaged unit
The air conditioning section of the packaged unit includes a DX cooling or heating coil (heat pump), and one filter monitoring with a supply fan. This solution can manage the air conditioner sector well.
Condensing section
In the condensing section, it can easily control one or two circuits and a maximum of two compressors in each circuit.
Important features of mini packaged u.VENT series controller
An important point in this solution is that the fan control settings can be selected, which means that in this solution you can choose the type of fan control as ON/OFF or gradual (for example, 0 to 10 V output).
It can be set in such a way that each group of fans comes into the circuit at a specific pressure of the refrigerant that the condenser pressure sensor reads.
Other functions such as the set point can also be defined and adjusted by a PID control loop for each circuit.
The user-friendly packaged control software is a Vida brand and is used to launch a small scroll packaged.
KARA RAVESH SABA Company has designed this program so that a set of required operational functions and all the hardware facilities are presented to the customers in the form of a solution.
The features of this software program are such that it covers all the needs of a scroll packaged with small-scale cooling power. In terms of hardware, the mini packaged (u.VENT) controller is provided with all the facilities needed to launch compression packaged. Among its most important features are the settings through the mobile application, which has a user-friendly and attractive software environment. You can connect to the controller through this application and Bluetooth or NFC connection. After setting various parameters, you can start it. In this method, it is also possible to save settings and report errors. Another advantage of NFC is that software settings can be made without powering up the system.

Using a PID control loop
A PID control loop can be selected for each circuit to control and adjust the superheat in the evaporator. For this purpose, a driver is selected for each circuit along with an expansion valve with a suitable size (based on the design) that can control the temperature of the superheat. The Superheat temperature control equipment is designed in such a way that with the lowest energy loss, it can quickly bring the Superheat temperature to the set point and is competitive in every respect compared to other similar systems offered in the market. The advanced technology of manufacturing CAREL control valves allows this operation to be performed with high speed and accuracy. One of the important control functions that can be activated or deactivated is the management of the rotation of the compressors (Rotation), which can be selected that activated by the user in this program.
Mini packaged (u.VENT) controller in the air conditioner part, it is possible to control a simple packaged unit by selecting the type of fan control (Supply) as ON/OFF. It is also possible to control the temperature of supply and return positions. Before starting up, all active equipment such as fans, valves and compressors can be manually activated or deactivated for testing.
Monitoring and supervision Systems
In the event series mini packaged (u.VENT) controller, there are wide possibilities in the supervisory. By default, Modbus RTU protocols can be used. Therefore, to use this equipment in the building management system (BMS), these systems can be easily controlled and operated based on predefined addresses. One of the wide features offered by the VIDA brand is a plug-and-play monitoring system This solution makes the users of such systems unnecessary to create expensive monitoring systems.
V.CLOUD systems provide the possibility of creating a local monitoring structure or a remote connection quickly and without the need to create an expensive monitoring infrastructure. They can also automatically identify the information and performance of air conditioning systems and other subsystems of the Vida brand without the need for any software programming operations, and store the obtained information themselves. The operator can view the performance report of these systems (trend) in the form of quality and nice graphic diagrams and images and use it to analyze data (Data Acquisition) to optimize the systems at the installation site or in the test room.
Also, similar facilities have been designed in a cloud space for equipment monitoring called V.CLOUD.
By using the Internet of Things or IoT (Internet of Things) technology and the membership of the users in this system, they will have the possibility to access the managed systems remotely. In this way, it provides them with a wide range of services including optimization, setup, monitoring, and control. In the event series mini packaged (u.VENT) controller, a variety of user interfaces are available, such as a color HMI display (Human Machine Interface), with different dimensions (4.3, 7, 10 inches). A phone application is usually used to quickly make settings, which makes it very useful when setting and commissioning the packaged unit due to its suitability for operation.
