Specification

Halton HME can be used for air distribution and sound attenuation in various applications such as suites and pantries. The unit operates as a plenum box with a balancing and measurement module inside but also fulfils fire safety requirements as standard cabin unit. The supply volume flow rate is determined during commissioning by using the measurement and adjustment device. The airflow measurement tubes and control spindle can be accessed through the unit’s outlet. Using the pressure difference readings between the measurement taps and the k coefficient, the corresponding volume flow rate can be calculated. Rotating the control spindle adjusts the volume flow rate until the desired setting is achieved.

Function

Correct airflow for HME unit is set during commissioning by adjusting MSM/MEM device in inlet spigot. MSM/MEM is operated by flexible spindle which is easy to access from outlet.

Models with reheater

When passenger demands for warmer temperature by using contol panel, the controller activates the electric reheater inside the cabin unit. When the required temperature in the cabin is achieved, the reference is held until the temperature demand changes.

Installation

Cabin unit mounting instruction

Projects requirements and possibilities should be taken into account when designing the installation. For more information on the possibilities contact Halton Marine sales office.

Main principles in cabin unit installation:
  1. Fix cabin unit above false ceiling using thread bar (as seen on picture) or frame installation
  2. Connect power supply and IC cable to the unit. (cable installation should be done before this phase, see Interconnection Cable Mounting Instructions). As standard cabin unit has Ensto NAC 31 plug for the power supply (counterpart NAC 32 not include).
  3. Connect supply air ducts to cabin unit inlets.
  4. Close maintenance / installation hatch.
  5. Connect and assemble diffuser to the cabin unit outlet.

Control Panel mounting instruction

  1. Install LRC-1 CP unit back plate to the provided leveled place on the wall.
  2. Fasten 3 screws (DIN 7981 or similar, Ø 3mm, max. head height 3 mm ) to fix CP unit to its place.
  3. Connect LRC-1 interconnection cable to the interconnection connector. Max. allowed tractive force is 30N.
  4. Install LRC-1 CP unit front plate to the back plate
  5. Fasten the screw in the bottom carefully. Max. Torque 0,3 Nm.

The LRC-1 CP unit should be positioned on the wall inside the room it will regulate. It is advised to avoid direct sunlight or position near heating/cooling source object

Interconnection Cable mounting instructions

Interconnection cable comes prefabricated with plugs on both sides. To install, draw it through the provided tube from Cabin unit to CP unit (the plug on CP unit is small enough to allow drawing through Ø 16 mm tubes). Max. allowed tractive force is 30 N. On the CP side, in the room, leave approximately 8 cm of the cable (the wires) outside the tube. The near end of the tube (CP-unit side) must be blocked (e.g. foam) to prevent condensation and thermal transfers reaching CP unit.

Safety distances

A required safety distance as illustrated must be taken into account when installing the cabin unit. Airflow measurement accuracy cannot be guaranteed if safety distance is not taken into account.

Adjustment

The supply flow rate is determined by using the measurement and adjustment module MSM.
The tubes and control spindle are passed through the diffuser. Measure the differential pressure with a manometer. The flow rate is calculated using the formula below.

qv = airflow (m3/h)
k = k factor
∆pM = measured pressure (Pa)

K-factors for installations with different safety distances (D = duct diameter)

HME >8xD 8…3xD
HME-125 29.2 40.7
HME-160 59.8 72.7

Adjust the airflow rate by rotating the control spindle until the desired setting is achieved.
Replace the tubes and spindle into the plenum.

Commissioning

All parameters can be preset at the factory according to order. During commissioning all parameters can be modified wirelessly with a PDA handheld device using LRC manager software.

Halton also provides supervision and commissioning services for the projects.
