Use of the Xhouse unit
1.3.1.
Unit Designation
-
The Xhouse unit is an air-handling unit using ventilation technology with heat recovery (counter-current
heat exchanger) and moisture recovery (enthalpy exchanger) with the possibility of connecting an
independent air heater (not included in the unit). The unit can be operated in two ventilation regimes:
o
Manual - forced ventilation. The unit ventilates according to the power set by the user
o
Automatic - ventilation according to air quality sensors (AQS). Air quality sensors CO
2
and RH can be
connected to the unit (accessories “NL-ECO-CO2” and “NL-ECO-RH”), which allow the unit to
ventilate only when necessary. If more sensors are required, up to 8 CO
2
and 8 RH sensors can be
connected using the “PRO-SUM-08” accessory. The user only sets the power of the unit (flow rate)
according to the required air exchange (number of people) in the ventilated and the unit ventilates
according to the actual need.
-
The unit can also be connected and controlled remotely by the BMS system using the modbus RTU
communication protocol. Addressed in separate chapter 4.2.5.
-
The unit can be used for air handling systems with a maximum requirement for a nominal flow of approx.
300 m
3
/h (depending on the type).
-
The unit is designed for vertical wall mounting only, so that fresh air supply can be provided.
-
The unit is intended for continuous operation with the possibility of using the manual operation regime
(ventilates continuously) or the automatic operation regime (ventilates as needed – required by the air
quality sensors – AQS).
-
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 maximum working altitude of the unit is 2,000 m above sea level.
-
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 the Xhouse unit:
-
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,
-
In an environment with higher condensation humidity, such as: bathrooms, swimming pools, saunas,
etc.,
-
The unit must not be installed just below the electrical socket or wiring box,
-
Neither the manufacturer nor the supplier is liable for damage caused by improper use of the units (e.g.:
drying out of new buildings). The user bears the risk.
1.4.
Transport, Delivery Control, and Storage
1.4.1.
Transport
-
During transport, keep the product in the position indicated by the symbol on the packaging.
-
The packaging must not be loaded with a weight higher than that permitted by the manufacturer.
-
The packaging must not be exposed to ambient effects.
-
The transport air temperature must range between -25 to 55 °C,
-
The transport relative humidity must range between 10 % and 90 % non-condensing.
-
Use adequate tools to prevent damage to the goods and damage to the health and safety of persons.
-
In the case of further transport without original packaging or with changed original packaging, it must be
ensured that the equipment is optimally secured and protected against damage.
