VEX100 seriesAir handling units with cross-flow heat exchanger

VEX140: 400-2200 m3/h

VEX150: 700-3600 m3/h

VEX160: 1100-5000 m3/h

VEX170: 1400-8400 m3/h

Heating coil, water or electricVEX100 units are supplied with integrated post-heat-ing coil, either for water or electricity.

Effi cient cross-fl ow heat exchangerThe cross-fl ow heat exchanger is made of aluminium with low pressure loss and a high temperature effi ciency. The cross-fl ow heat exchanger ensures complete separation between the air passages, so no smells or impurities are transfered to the supply air.

Effi cient vibration suppressionThe fans are suspended on a track system, which makes pulling out and servicing easy. The design of the suspension system, with the motor, impeller and intake together suppresses vibrations very effectively.

One range - Lots of possibilities

The VEX100 unit can be supplied with the air supply on either the left-hand or right-hand side. Spigots can be placed on the sides and the top/bottom as required. Units in the VEX100 series are available as horizontal or vertical units (the VEX140 is also available as a ceiling-mounted unit).

VDI6022 All EXHAUSTO units have been independently certifi ed in accordance with the German standard, VDI 6022.

Specify the desired spigot position (A or B) when placing your order.* Allow a service distance equal to the depth of the unit in front of the unit.** Allow min. 200 mm free height for service.

The height (1800 mm) is when the feet of the base are set at standard length. The feet are adjustable which makes the height variable within the interval of 1750-1840 mm.NB: The water trap on the condensation outlet requires a certain amount of free height – a height of 1800 mm is adequate.

Regulation The VEX100 control system meets all the control requirements for maintaining a perfect indoor climate. As standard there is an option to control the VEX100 from the DDC unit via LONWORKS® or EXHAUSTO’s iTool Internet server, which gives a direct connection to the VEX from your PC.

Several operating levels - save energy The control system features a range of options designed to save energy when operating in economy and standby modes (see fig. 1).

Regulation principlesThe control system controls the built-in heating coil (water or electric) in sequence with a bypass and a cooling unit, if used, (fig. 2).

The control offers options for regulating the room tempera-ture or the supply air.

VEX100 Control system - Standard functions

Fig. 1: Example of temperature set point for comfort, standby and economy operation

The control system regulates the damper (heat recovery effect) to maintain the required T-comfort of 22 °C.

With T-comfort, it is set to how close to the 22°C temperature is required, either heating (22-1 = 21 °C) or cooling (22+1 = 23 °C).

Standby operation with low airflow (step1) gives the option to achieve even greater savings by setting to T-standby.

As shown above, this is achieved with heating 22-3=19 °C, and with cooling 22+3 = 25 °C when the unit is in standby.

With economy heating the setting is an absolute temperature, such as 16 °C for heating and 30 °C for cooling. This allows the option to lower the temperature during heating and that the cooling unit only starts when the temperature rises above 30 °C.

With the control of the cooling unit there is also an option to set the max. tempera-ture difference T between the room and supply air temperature.

Night-time coolingWithout any extra equipment, night-time cooling can be selected, which functions without any cooling unit being attached.In buildings with large mass (weight) the comfort in summer can be improved by cooling the building with cool outdoor air at night. Night-time cooling is particularly suitable for offices, instituti-ons, etc. where people do not work at night.Night-time cooling can only be activated during the summer and when the unit is not in comfort operating mode. It is possible to set a temperature and a time for night-time cooling.

Frost protection of water heating coilsFrost protection of water heating coils is controlled by temperature sensors on the return pipe. If during operation the temperature falls under the set temperature, the unit stops. When the unit stops a heat retention function starts which keeps the water in the return pipe at a set temperature. This minimises the risk of frost in the heating coil and the unit is ready to start immediately even when the temperatures outside are low. There is also an built-in control to run the circulation pump during periods when heating is not required.

Room temperature controlRoom temperature is controlled by means of the built-in tem-perature sensor or an external room sensor.When regulating the room temperature there is also an option for summer compensation (fig. 3).When summer compensation is selected, the set point for the desired room temperature will increase in line with the outside temperature. This avoids an unpleasant cold shock because of too great a difference between the indoor and outdoor temperature, and also saves energy.

Supply air regulationWhen regulating the supply air temperature there is an option for outdoor compensation (fig 4). When this is selected the set point for the supply air temperature is lowered in summer (and possibly raised in winter) and so the supply air tempera-ture is compensated on the basis of the outdoor temperature.The temperature is compensated by the built-in temperature sensor in the outside outdoor air spigot.

Advanced standard functions

34

In addition to the numerous standard functions there are also options, such as:

• Airflow control to maintain the airflow rate even if the filters are dirty etc. The airflow is shown in the DISPLAY panel.• Airflow control is a requirement with a cooling unit in order to monitor the minimum airflow• Detecting ice in the cross-flow heat exchanger on the basis of pressure measurement (requires airflow control)

The functions listed above can be fitted to the VEX unit to order.

Example of control of airflow with CO2 and/or humidity override

VEX100 Control system - Options

When the automatic control system is operative, this func-tion can be used to increase the required airflow when the CO2/humidity concentration in the room increases

Starting the unitOn starting the unit always runs for a few minutes with ex-traction to warm up the cross-flow heat exchanger before the supply air is started.

Run on with electric heating coilWith an electric heating coil there is a built-in run on, so the fan runs for three minutes after the unit stops. During these 3 min. the heating coil is disconnected.

Outside compensation of airflowThe control system has a built-in function for reducing the airflow when the outdoor temperature is falling. The tempera-ture is measured in the outdoor air spigot.

Filter controlThere are built-in filter controls in the unit. These are located in the connection box and can easily be set during operation. If a filter needs to be changed a yellow lamp lights up on the DISPLAY and TOUCH-panel and an entry is made in the alarm list.

De-icing functionThe de-icing function is activated on the basis of a set tempe-rature measured at the exhaust spigot. When the function is activated, the supply airflow is reduced to 1 step, or bypass de-icing takes place.

Bypass de-icing is carried out through the following procedure: • The control system registers icing on the cross-flow heat exchanger• The bypass damper opens slowly (10% per minute). The normal temperature control system will deal with opening the motor valve and supplying post-heat.

Example of ZONE control with modulating damper and constant pressure regulation

• Constant pressure regulation of the flow of extract and/or supply air

• CO2 sensor for overriding the fan speed

• Humidity sensor (RH) for overriding the fan speed

• ZONE control of local on/off damper via, for example, manual activation, PIR sensor (Passive Infrared Receiver or hygrostat on/off)

• ZONE control of local modulating damper (0-10V control voltage) via, for example CO2 or humidity sensor

External units operate via the EXHAUSTO Operating Network (EON), which is a bus-based network.With the start and initial adjustment of the unit the control system checks what units are linked to the network. During day-to-day operation, the control system monitors all the units that are operating and provides information about any errors that may occur. The units to be linked to the network should be positioned in a structured manner, like a daisy chain.The signal cable is a 4-wire cable (2x2x0.6mm) where 2 wires are used for the electric current (24VDC) and 2 are used for communication.Service can be carried out quickly without affecting the other units in the network, as one module can be removed without breaking the connection to the others (the cable is looped onto plug terminals). For servicing, an extra DISPLAY panel can be linked to the VEX. This has to be done in specialist mode and overrides the normal operation of the unit.

Simplified diagram- VEX100 with water heating coil (HCW) - for third party control system

VEX100 for third party control systems

Freedom to chooseAs alternatives all VEX100 units offer a solution with a diffe-rent control system. VEX100 for third party control system can be delivered with or without frequency converter. This allows integrating the VEX100 units with a control system from other suppliers. The solution is optimised for simple and efficient integration on site.

The following table shows which components are included in a VEX100 for another control.

The connections are all made at the same placeTo make the fitting and integration as simple as possible, allthe connections are collected on a terminal board. The motor

cables, connections to the electric heating coil, hoses for flowvolume measurement and pressure loss are led to the terminalboard. The bypass-motors are tested and fitted, and theconnections led to the terminal board.The water heating coil is fitted and the connections are led outthrough the cabinet.

CapacityThe solution for third party control system is supplied withthe same highly efficient motor as the VEX100 units withintegrated control. VEX170 with motor size 1 can only be delivered with frequency converter.

• VEX100 SPLIT is the right choice for buildings where it is difficult to move a full size unit in

• Cost savings on repairing walls and roofs• The biggest and heaviest component is the cross-flow heat exchanger (see dimensions in table below)• After the cross-flow heat exchanger the heaviest component is

the motor section (see weights in the table below)• The unit must be fitted by personnel approved by EXHAUSTO• The unit should be final-tested before the fitters leave

Guaranteed air quality - VDI6022

To ensure that the VEX100 meets the rigorous hygiene re-quirements that currently apply to ventilation equipment, the unit has been tested and approved by ILH Berlin (Institut für Lufthygiene) in accordance with VDI 6022.

VDI6022 versions of VEX100 units are supplied with an F7VDI filter on the outdoor air, and external display of the filter pres-sure loss on the U pipe manometer fitted on the cover.

The VEX100 is designed:• to minimise bacterial growth and dirt accumulation• for optimal cleaning– in order to fulfil VDI 6022 (ILH Berlin).

Outdoor fittingThe VEX100 cabinet is insulated with 50mm mineral wool, and so is suitable for outdoor fitting. For outdoor fitting the VEX is supplied with a complete roof with service hatch which ensures easy access to the control system.

The roof is designed so that cables can be led under it to both sides and to the back of the cabinet. The motor valves and damper can also be supplied in a model for outdoor fitting.

The cross-flow heat exchanger can easily be removed from the unit for cleaning, although the connection to the bypass motor must be disconnected (remove the plug).

The compact filter can very easily be changed by pulling out the filter cartridge and putting in the new filter.

The fan sections are suspended in track systems which make pulling them out and servicing them easy. The motor, impeller and inlet are collected together in the track system. This gives extra effective vibration suppression.

Service and maintenance

EXHAUSTO products are reliable and solid solutions. But even the best solutions require continuous maintenance and service to ensure problem free operation.

We have made the VEX100 range as easy as possible to ser-vice continuously. Replacing the filters protects against dirt on the cross-flow exchanger and the impeller and prolongs the lifetime of the unit.

Operational reliability requires regular maintenance
