Ventilation & sanitary hot water

Nilan’s VP 18 range consists of heat recovery systems that ventilate your home, and not only heat the fresh, incoming air but also your sanitary hot water. In other words, you get a healthy indoor climate and a low heating bill in one single solution.

The hot, humid air is extracted from the kitchen, bathroom and utility room, thus removing dust particles, humidity and odours from the home. At the same time, the system recovers the heat from the extract air and uses it to heat your sanitary hot water and draw fresh, pre-heated inlet air into the rooms of the home.

Moreover, the VP 18 EK model provides heating of your home via connection to a water-filled central heating system. This enables you to cut back on heating expenses even further.

VP 18 Cooling Solar

The VP 18 Cooling Solar system is for anyone who wants highly efficient heat recovery, an extraordinarily high production of sanitary hot water, and comfort heating and cooling.

The system extracts hot, humid air from the home and at the same time removes dust particles, moisture and odours. Furthermore, the energy from the extract air is used to heat both sanitary hot water and incoming air. The system is equipped with a built-in heating coil, which can be combined with the primary heating system to supply extra sanitary hot water for use e.g. in a spa bath. The system’s cooling facility actively cools the incoming air to approximately 10 °C below the outside temperature.

When you buy a VP 18 Cooling Solar system, you get a comfortable and healthy indoor climate and cost savings on your heating bill.The VP 18 Cooling Solar is a compact system that takes up no more space than an ordinary tall cupboard.

The VP 18 unit is designed for installation in utility or technical rooms and is suitable for homes with an air exchange requirement of up to 300 m3/h.

The unit combines ventilation with active heat recovery, production of hot water and comfort heating, in one compact, space-saving solution.

VP 18 is the obvious choice for homes with limited space, as it does not require more space than an ordinary wall cabinet. This should be compared to solutions with separate ventilation, heating and hot water installations, which can soon fill up a utility or technical room.

Select VP 18 with cooling and solar function, for cooling of the supply air and if there is a need for extra hot water, e.g. a spa bath.

Cooling function
A newly built house will be well-sealed and insulated, making it is easy to keep warm, but during hot spells it may be difficult to keep the home cool. The VP 18 cooling function operates via the reversible cooling circuit that can cool the outdoor air by up to 10 °C. This is not the same as air conditioning, however, but when the supply air is cooled down, the level of humidity in the home will decrease, making the indoor climate more comfortable.

Solar function
With the help of an extra heating element, the unit can be connected to a solar panel, oil, gas or other fuel source, to increase the production of hot water.

EM-box

An EM-box allows heat recovery from the air from the range hood and thereby helps to heat the supply air. The EM-box is equipped with a steel filter which efficiently cleans the range hood air of fat particles and thereby protects the system (expansion PCB required).

 

Expansion PCB

The expansion PCB provides additional functions for the CTS 602 control unit.

Pollen filter - ISO ePM1 50-65%

A pollen filter class ISO ePM1 50-65% can be fitted in the unit. The pollen filter is fitted with the ISO Coarse >90% (G4) plate filter.

CO2-sensor – CTS 602 control

With a CO2-sensor installed, the ventilation speed can be pre-programmed with CTS 602 to run at a higher ventilation steps when CO2 reaches high level in the extract air. CO2-level is programmable (expansion PCB required).

Capacity

Capacity of standard unit as a function of af qv and Pt, ext.

SEL values according to EN 13141-7 are for standard units with standard filters ISO Coarse >90% (G4) and without heating element.

SEL values comprise the unit´s total power comsumption incl. control.

Conversion factior: J/m3 : 3600 = W/m3/h

Sound data

Sounddata is for qv = 210 m3/h and Pt, ext = 100 Pa in accordance with EN 9614-2 for surface and EN 5136 for ducts. 

Sound output level LWA drops with falling air volumes and falling back-pressure.

At a given distance, the sound pressure level LpA will depend on the acoustic conditions at the installation site.

COP (air-air)

Heat output factor COP [-] supply air as a function of outdoor temperature t21 [°C] and volume flow qv [m3/h] in accordance with EN14511 at a room temperature t11 = 21°C

Tapped water

Tapped volume in litres Vmax [L] from VP 18 tank as a function of tapped temperature t [C°] and tank temperature at 40°, 50° and 60°C

Heat output supply air

Heat output Qc [W] as a function of qv [m3/h] and outdoor air temperature t21 [°C]. In accordance with EN 14511, t11=21°C (extract air)

Heat output is the contribution to room heating added to the fresh air via VP 18 to the supply air.

The ventilation loss is the heat output that is lost without heat recovery at the given volume flow air.

Connections
1: Fresh air
2: Supply air
3: Extract air
4: Discharge air

The VP 18 Cooling Solar is controlled using its CTS 602 operating panel, featuring a wide range of functions, e.g., menu-controlled operation, weekly programme settings, filter monitor with timer, fan speed adjustment, summer bypass (free cooling), post-heating element control, error messages etc.

The CTS 602 comes with factory settings, including a default setting which can be customised to operational requirements to achieve optimum operation and utilisation of the system.

The operating panel must be placed in a dry, frost-free location, at least 1.5 m above floor level and at least 0.5 m from any corner. Avoid placing the panel on an external wall or in areas in direct sunlight.

Operating instructions for the CTS 602 can be found in a separate user manual supplied with the unit.
