Halton Vita Patient Ava is a complete room unit with integrated radiant cooling and heating combined with a unique protective airflow pattern. The room unit provides comfortable indoor climate conditions for patients and a safe working environment for medical staff. Halton Vita Patient Ava is part of the Halton Vita Patient solutions offering.
The Halton Vita Patient Ava room unit combines supply air distribution with a radiant panel and automation, which makes it a complete solution for patient rooms.
The radiant panel is used for ensuring individual thermal comfort. The cool or heat is transferred from the water flowing through the radiant panel’s copper pipe to the aluminium sheet that works as a radiant surface to the surrounding space.
To reduce the risk of infections and enhance the protection of medical staff, the Halton Vita Patient Ava room unit provides a unique protective airflow pattern. The solution protects the medical staff by generating a barrier from the supply air, at the same time maintaining thermal comfort for the patient.
When equipped with the Halton Vita Room Automation system and a VAV airflow damper, the Halton Vita Patient Ava room unit has three different operating modes:
With the boost operating mode, the supply airflow is designed to generate a protective airflow pattern that prevents bacteria exhaled by the patient from entering the breathing zone of medical staff. At the same time, fresh, clean air is brought to the breathing zone of medical staff.
Fig. 2. Protective airflow pattern. Left: Normal mode. Right: Boost mode with protective airflow pattern.
The Halton Vita Room Automation system can be designed so that it enables individual control for each patient separately, which makes it possible for patients to control the temperature level according to their individual needs.
The temperature level is controlled by adjusting the flow rate and temperature of the water circulating in the copper pipes. As a result, the thermal comfort of the patient is optimised. If necessary, the cooling capacity can be enhanced by increasing the airflow rate.
The cooling capacity of radiant panels is measured according to EN 14240. The installation type (ceiling-integrated or exposed ceiling installation) affects the output performance. Therefore, in the Halton HIT Design software, where the cooling and heating capacity can be checked for each case, the installation type should be selected to get more specific output data.
The heating capacity of radiant panels is measured according to EN 14037:2016. The heating capacity of Halton radiant panels has been measured in an accredited third-party laboratory to fulfil the requirements of EN 14037-2.

The system package should be selected in the Halton Vita Patient Ava (VPA) product order code when the product is intended to be equipped with Halton Vita VRA room automation system.
The package consists of a controller unit and a user panel used to adjust the ventilation airflow, room temperature, and lighting in a hospital patient room.
Fig 5. Automation control unit and a user panel
The controller unit is installed on top of the panel and the user panel on the wall.

You can find more detailed information about the system package under Halton Vita VRA room automation product pages.
Halton Vita Patient Ava room units are suitable for ceiling-integrated and exposed ceiling installation.
To ensure the protective airflow pattern, the Halton Vita Patient Ava room unit should be installed above each patient bed in a patient room. The end with the water connections should come above the head end of the patient bed. The distance between the end wall and the unit should be 600 mm.
The required free height from the lowest point of the front panel to the ceiling is 341 mm.
Enough space must be reserved around the unit for maintenance. If there is a solid ceiling, there must be a service hatch close to the unit, to enable access to the top of the unit.
The unit is installed by suspending it from the ceiling using wires and snap hooks.
Fig. 7. Halton Vita Patient Ava installation
NOTE: Wires, snap hooks and flexible hoses are not included in the delivery.
To enable the protective airflow pattern, the nozzles are directed towards the longitudinal centre line of the room unit. If necessary, the direction of the nozzles can be adjusted.
The recommended cooling water mass flow rate is 0.020…0.035 kg/s, resulting in a temperature rise of 1…3°C in the radiant panel. To avoid condensation, the recommended temperature of the inlet water is over the dew point temperature of the room.
The recommended heating water mass flow rate is 0.015…0.030 kg/s, resulting in a temperature drop of 3…10°C in the radiant panel. In typical rooms (room height up to 3 m), the usual recommended maximum temperature of the inlet water is 50°C due to a risk of the radiation asymmetry being too high.

There are two inspection hatches to enable cleaning the air chamber of the unit.
If installed exposed, it is recommended that the top of the unit is vacuumed.
For cleaning frequency, follow the maintenance schedule of the building.
