概览

Halton Vita Patient Ava (VPA)是一个完整的病房装置,集成辐射制冷和制热,并结合了独特的保护气流模式。Halton VPA 为患者提供舒适的室内气候条件,为医务人员提供安全的工作环境。 Halton Vita Patient Ava (VPA)是Halton Vita 患者解决方案的一部分。

应用

  • 医院病房

主要特点

  • 辐射制冷和制热,并带有送风分配,以满足舒适和最佳的室内气候条件。
  • 保护性气流模式,为患者和医务人员提供安全的环境。
  • 低而光滑的设计,表面卫生,易于清洁。
  • 适用于天花板整合暗装或明装
  • 病房操作模式控制的完整解决方案。
  • 自动化系统,易于使用的界面,可以确保在不同操作模式下的灵活性和最佳性能。

工作原理

The Halton Vita Patient Ava (VPA) 将送风分配和辐射板与自动化相结合,使其成为病房的完整解决方案。
辐射板用于确保个人的热舒适性。通过辐射板铜管里的水流,冷热量传导至铝板,铝板作为辐射表面将温度传递至周围环境。

保护气流模式

为了降低感染风险并加强对医务人员的保护,Halton Vita Patient Ava (VPA)提供了独特的保护气流模式。该解决方案通过产生一个来自送风的屏障来保护医务人员,同时保持患者的热舒适。

当配备Halton Vita 病房自动化系统和VAV变风量阀时,Halton Vita Patient Ava (VPA)具有三种不同的操作模式:

  • 空病房待机(分钟)—— 与有人时的(正常)操作模式下配置的气流速率相比,Halton Vita 病房自动化控制器可降低气流速率。
  • 有人时(正常),对于有一个或多个患者的房间 —— 根据病房中的患者数量配置气流速度,Halton Vita 病房自动化控制器保持配置的气流速度。
  • 增压(最大值),适用于医务人员或其他人员与患者在同一病房的情况——Halton Vita 病房自动化控制器可增加气流速度。

在增压操作模式下,送风气流旨在产生保护性气流模式,防止患者呼出的细菌进入医务人员的呼吸区。同时,新鲜、清洁的空气被带到医务人员的呼吸区。

热舒适性

Halton Vita 病房自动化系统的设计可以使每个患者都能对房间进行单独控制,从而使患者能够根据自己的需求控制温度水平。温度水平通过调节铜管中循环水的流速和温度来控制。因此,患者的热舒适度得到了优化。如有必要,还可通过增加气流速度来增强制冷量。

制冷制热量

辐射板的冷却量根据EN 14240进行测量。安装类型(天花板一体化暗装或明装)会影响输出性能。因此,在Halton HIT设计软件中,可以检查每种情况下的制冷和制热量,应选择安装类型以获得更具体的输出数据。

辐射板的制热量根据EN 14037:2016进行测量。Halton辐射板的制热量已在经认证的第三方实验室进行测量,以满足EN 14037-2的要求。

System package

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.

Specification

  • A room unit designed for hospital patient rooms.
  • Combines radiant cooling and heating with supply air distribution.
  • The room unit is equipped with an automation system that enables three different operating modes, airflow control, as well as the temperature and lighting control of the patient room.
  • The pre-programmed and pre-tested automation system includes a hygienic user panel for adjusting the operating mode, room temperature, and lighting of the room.
  • With the automation system and a VAV airflow damper, the room unit increases the airflow rate and provides an airflow pattern that protects the medical staff from bacteria exhaled by the patient.

Structure

  • Unit length 2400 or 3000 mm.
  • Unit width 1200 mm, thickness 75 mm.
  • Inlet duct diameter 160 mm.
  • Pipework’s maximum operating pressure 1.0 MPa.
  • There are two inspection hatches to enable cleaning the air chamber of the unit.

Materials

  • Front panel manufactured from aluminium.
  • Duct connection and related parts manufactured from galvanised steel.
  • All visible parts painted. White antibacterial epoxy polyester powder paint (RAL 9003).
  • All pipes manufactured from copper.
  • All pipe joints soldered.
  • All pipe joints pressure-tested at the factory.

Packaging and identification

  • The visible surface of the product is protected by a removable plastic coating.
  • The duct connection and pipe ends remain sealed during transport.
  • The product is packed on a pallet.
  • The product is identified by a serial number printed on labels attached both to the product and the package.

Design information

When designing a patient room, consider the following:

  • To ensure the protective airflow pattern, the Halton Vita Patient Ava room unit should be installed above each patient bed in a patient room.
  • Are both cooling and heating functions needed?
    • The room unit can be equipped with one or two water loops. Typically, loop 1 is used for cooling and loop 2 for heating.
    • To enable individual temperature control for patients, it is recommended that the room unit is equipped with two water loops (cooling and heating) and Halton Vita Room Automation.
  • If a patient room has several beds, it is recommended that the airflow and temperature can be individually adjusted for each patient. This enables the protective airflow pattern for medical staff or other people around individual beds.
    • If needed, it is possible to control the whole room as one area. In this case, the airflow dampers are located in the main ducts of the room, not in the room unit branches.
  • Is it possible to open the windows in the room?
    • If it is possible to open the windows in the room, it is recommended that window switches are used. A window switch detects whether a window is open or closed. If the window is open, the cooling valve is closed to prevent condensation. The window switch is an accessory available separately and needs to be specified in the design documents.
  • How are the lights in the patient room controlled?
    • The Halton Vita Room Automation controller uses Digital Addressable Lighting Interface (DALI) for controlling the lighting: switching the lights on or off, dimming the lights, or controlling the lights in groups.

Installation

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.

NOTE: Wires, snap hooks and flexible hoses are not included in the delivery.

Commissioning

Airflow adjustment

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.

Cooling

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.

Heating

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.
