Compact P

The Compact P is a modular compact system that offers not only one but several solutions, thus enabling you to select the solution must suitably proportioned to match the size of your house and accommodate the requirements of your family.

The first step in a Compact P solution is always the Compact P itself, i.e. the basic unit. The Compact P is a complementary ventilation and heating system that provides your house with ventilation, heat recovery and production of sanitary hot water. It ensures a daily air exchange with the removal of dust particles, smells and excess humidity in exchange for a pleasant and healthy indoor climate. When it is hotter inside than outside the house, a built-in bypass makes sure to let cool air directly into the house.

If you want a total solution that covers central heating of the house as well, you should choose a Compact P solution with an outdoor air or ground source heat pump.

Compact P is, as only one out of a few compact systems in the world, passive house certified due to its high efficiency. The certification means that the Compact P is pre-approved for passive housing without any additional documentation ever being needed.

Compact P is an energy-efficient total indoor climate solution for all types of low-energy buildings, single-family homes, flats and small office areas in commercial leases with a ventilation requirement of up to 300 m3/h. Compact P has a 180 l hot water tank. 2 layers of glass enamelling to ensure a long lifetime.

Compact P recovers the energy from the extracted air using a highly efficient counter flow heat exchanger. The remaining energy that is not utilised by the counter flow heat exchanger is used by the heat pump to produce hot water, and to further heat the supply air.

The heat pump has a reversible cooling circuit, which means that, in the summer, the unit can cool the supply air by up to 10 °C. Due to the low air exchange, the cooling does not function as an air conditioning system. On cooling, the supply air is dehumidified, which gives a more pleasant indoor climate than is possible with an ordinary ventilation unit without a heat pump.

Compact P is also offered in a Polar version with a built-in preheating element to frost proof the counterflow heat exchanger.

Solar

Extra heat exchanger of 0.7 m2 in the hot water tank, which can be connected to an approximately 3 m2 solar heating system, or other heat sources.

Electrical pre-heating element (Frost protection)

An electrical pre-heating element heats up the outdoor air before it enters the unit. This avoids having to defrost the unit, resulting in a loss of power.

There are temperature sensors supplied to be fitted in the ducts.

Top cover

To cover the ducting over the unit, Nilan offers a top cover in white-varnished aluzinc (RAL 9016).

CO2-sensor - CTS 700 control

With a CO2-sensor installed, the ventilation speed can be pre-programmed with CTS 700 to run at a higher ventilation steps when CO2 reaches high level in the extract air. CO2-level is programmable.

Pollen filter F7

A pollen filter class F7 can be fitted in the unit. The pollen filter is fitted with the G4 plate filter.

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.

 

Electrical pre-heating element (Frost protection)

An electrical pre-heating element heats up the outdoor air before it enters the unit. This avoids having to defrost the unit, resulting in a loss of power. There are
temperature sensors supplied to be fitted in the ducts.

(Integrated in the Polar version).

Electrical heating surface incl. regulation

When you fit an electrical heating surface, you can raise the fresh air temperature to the desired level at any time. The electrical heating surface is supplied ready to fit into the fresh air duct and, for easy fitting, the device is pre-fitted with all the required sensors.

 

Water heating element incl. regulation (duct mounted)

The supply temperature can always be raised to the required level using a water heating element. The water heating element is designed to be built into the duct and must be connected to the primary heating supply. Supplied with two-way adjustment valve, temperature sensor and frost thermostat.

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 G4 filters and without heating element.

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

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

Temperature efficiency

Temperature efficiency as a function of volume flow qv [m3/h] for unit with counterflow heat exchanger.

Temperature efficiency according to EN13141-7 (2°C / 20°C).

NB! The temperature efficiency, is for the heat exchanger only (without heat pump operation)

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

COP according EN14511 is calculated for the heat pump and counter flow heat exchanger combined.

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 Compact P to the supply air.

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

Tapped water

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

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

The Compact P is controlled by its CTS 700 touch panel, which provides a wide range of functions, including menu-controlled operation, week programmes, time-controlled filter monitor, fan speed adjustment, temperature control, error messages etc.

The CTS 700’s factory settings are default settings that can be adapted to operating needs and requirements, to achieve optimum operation and utilisation of the system.

Operating instructions for CTS 700 can be found in the separate user guide supplied with the system.
