3. Use of the Xroom unit
1.
Unit Designation
-
The Xroom is an air-conditioning unit using ventilation technology with recovery of heat (countercurrent
recovery exchanger) and humidity (enthalpy exchanger) with the possibility of independent space heating
at the unit’s installation site (depending on the selected unit type). By default, the unit is equipped with
a CO
2
air quality sensor (alternatively also with an RH humidity sensor), which allows it to ventilate only
when needed. The user shall set only the unit's output (flow rate, temperature – based on the selected
type) according to the place of use (how many people will be in the room) and the unit will ventilate and
heat as per the actual needs.
-
The unit can be used in spaces with the maximum nominal flow requirement:
o
100 m3/h – Xroom 100 – regular residential premises, smaller offices, hotel rooms, etc.
o
250 m3/h – Xroom 250 – larger office facilities, school classrooms, hospital rooms, etc.
-
The unit is designed for horizontal installation on the perimeter wall, which provides simple access to the
outside environment (fresh air).
-
You can install the unit in the wall with the minimum thickness of 180 mm.
-
The unit is intended for continuous operation with the possibility of using the manual operation mode
(ventilates continuously) or the automatic operation mode (ventilates as needed – required by the air
quality sensors – AQS).
-
The unit can be used not only for controlled ventilation, but also for space with heating requirements
(ventilation and heating are independent of each other). In case of type configuration with:
o
Electric heating, the unit is equipped with advanced regulation with temperature sensor for the
given area (installation site). Using an integrated temperature sensor, the user can choose the
appropriate temperature degree that meets his requirements,
o
Water heating, the unit is equipped with a water exchanger, which is connected to the standard
heating system using an external G 3/4" thread and is controlled using an independent fitting –
thermostatic valve and head (not included in the supply). The unit control is equipped with a
temperature sensor that detects hot water in the exchanger and starts the heating function. The
function of the water heater depends on the function of the boiler – heating system.
-
The unit also allows for the antifreeze temperature function (tempering the heated space to prevent
freezing). In the electric version, settings are on the controller, and in the water version, they are on the
thermal head (snowflake symbol).
-
The unit is intended for indoor covered and dry areas with a room temperature of +5 °C to +30 °C and the
maximum relative humidity of 70%, non-condensing.
-
The temperature of supplied fresh air from the outside may be between -20 °C and +40 °C (applies to
the version with preheating). If the temperature of the supplied air is lower than -20 °C, the unit may
be switched off automatically in order to protect it from possible damage.
1.3.2. Prohibited environment, use, installation of Xroom:
-
Exhausting burning or glowing substances!
-
Exhausting readily flammable or explosive gases,
-
Exhausting aggressive media,
-
Exhausting liquids of any kind,
-
In an environment with an increased incidence or risk of explosion, flammable substances, and
increased dust and/or air containing other harmful impurities,
