Patient rooms play a vital role in recovery and long‑hour medical work. Indoor temperature, air cleanliness, and hygienic maintenance directly affect patient experience and clinical safety.
The Halton Vita Patient Ava (VPA) is a complete room unit designed specifically for hospital patient rooms. It combines radiant heating/cooling with protective airflow technology, ensuring patient comfort while maintaining a safe working environment for medical staff.
Why choose Halton VPA?
- Conflicting thermal needs
Patients rest in bed with low metabolic activity, requiring a warm, draft‑free environment. Medical staff move actively with high metabolic rates, preferring cooler, cleaner air. Conventional systems try to maintain a uniform temperature for the whole room – often leaving either the patient or the staff thermally dissatisfied. - Risk of cross‑infection
Bacteria exhaled by patients can travel with room airflow and reach the breathing zone of healthcare workers, especially during close contact care. This poses a real threat to staff safety. - Dynamic room occupancy
Patient room occupancy changes constantly – empty, occupied by a patient only, or entered by multiple staff. Traditional systems cannot respond dynamically, leading to either wasted energy or inadequate protection.
These challenges point to one solution: an environmental control system that addresses diverse thermal needs, actively reduces infection risk, and intelligently adapts to changing room conditions.
Halton VPA’s Operating Principle
The Halton Vita Patient Ava room unit combines supply air distribution with a radiant panel and automation, making it a complete solution for patient rooms.
- Radiant temperature control
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. The temperature level is controlled by adjusting the flow rate and temperature of the water circulating in the copper pipes, thereby optimising the patient’s thermal comfort. - Protective airflow pattern
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 medical staff by generating a barrier from the supply air, at the same time maintaining thermal comfort for the patient. It prevents bacteria exhaled by the patient from entering the breathing zone of medical staff, while bringing fresh, clean air to the breathing zone of medical staff. - Operating mode control
When equipped with the Halton Vita Room Automation system and a VAV airflow damper, the Halton Vita Patient Ava room unit has three operating modes:- Standby (min) for empty rooms – the controller decreases the airflow rate.
- Occupied (normal) for rooms with one or more patients – the airflow rate is configured according to the number of patients.
- Boost (max) for situations where medical staff or other people are in the room – the controller increases the airflow rate. In boost mode, the supply airflow generates a protective airflow pattern that prevents bacteria exhaled by the patient from entering the breathing zone of medical staff, while delivering fresh, clean air to their breathing zone.
Modern healthcare spaces increasingly focus on both human‑centered design and safety. The Halton VPA radiant panel combines radiant heating and cooling with protective airflow, while also offering intelligent control and flexible adaptability. It improves the indoor climate for patient recovery and ensures a safe working environment for medical staff – making it a preferred solution for both new and renovated hospital patient rooms.
