PKOM 4

One device, 4 benefits.
Ventilation. Heating. Cooling. Hot Water.

Passive House Institute Certified. Sap Appendix Q Listed. Ecodesign.

The PKOM4 compact heat pump unites these four functions on a footprint of less than 0.75 m². Controlled ventilation of living rooms will constantly ensure fresh and filtered outside air in the rooms and ensure hygienic exchange of air. The highly efficient heat recovery system is also optionally available as a design with the recovery of waste air humidity. To prevent overly high summer temperatures in the living rooms, heat recovery may also be bypassed during cooler night hours by means of a bypass flap.

KNX can now be combined with all ventilation units including the PKOM4.

Two Compressors

Parallel operation of Heating / Cooling + Ventilation + Domestic Hot Water

Eco-Mode

When set up in Eco-Mode (Smart Grid) this function automatically changes the set point for domestic hot water to a higher temperature. The heat pump heats up the water to 55°C and then switches over to the immersion for heating up to 75°C.

A second option is given by intelligent control of the heat pump in cooling mode. A special configuration allows the activation of the heat pump for cooling only when the Eco-Mode is being activated. So the energy for cooling is covered 100% by the PV system.

2 versions:

PKOM4
classic
PKOM4
trend

The PKOM4 classic heat pump combi unit is the preferred compact overall solution for passive house construction homes with up to 130 m² living area. The volume of household hot water will comfortably provide for a family of 4.
A controlled heat pump will in addition condition the supply air, i.e. heated or cooled on demand.
Another heat pump is used for efficient provision of household hot water. Both heat pumps may be operated in parallel to ensure uninterrupted provision of air and water.

Household hot water storage and the associated heat pump are omitted in the PKOM4 trend unit version.
The PKOM4 trend heat pump combi unit is the best alternative to conventional living room ventilation units. The supply air into the living rooms will be cooled and dehumidified during summer, as needed. The supplied air will be heated in the colder months.

PKOM4 & PSOL+ system solution

Renewable Energy Integration

As a compact ventilation unit, the patented heat pump combi unit PKOM4 replaces a complete heating/cooling/service water system. The combination of renewable energies such as photovoltaics and an intelligent energy management system like PSOL+ makes the PKOM4 an efficient, cost-effective system solution with which operating costs are reduced to a minimum, thus making it possible to implement a zero-energy building or even a "plus energy" building.

Design

◉ Storage battery up to 11 kWh
◉ Hybrid inverter with emergency power function up to 10 kW
◉ Energy management for system optimisation
◉ One app/visualisation for the whole system solution.

Advantages

◉ Pre-assembled / installed overall solution
◉ Plug & play – easy, reliable
◉ Lower installation/energy costs
◉ Everything from one single source – one contact person
◉ One app / visualization
◉ Independent in the event of power failures – emergency power function
◉ High degree of personal energy usage of the photovoltaics system
