Product description

Compact P2 is a ventilation unit with heat recovery, that has a built-in heat pump, which is used for the production of domestic hot wa-
ter, and which is also able to heat and cool the home by central heating via a ground source heat pump.
Compact P2 is designed for air flows of up to 425 m3/h at 75 Pa external counter-pressure.
The unit is primarily used in residential construction such as single-family houses and apartments. It ventilates the home by drawing
out the moist and bad air via valves in e.g. bathrooms, toilet, kitchen and utility room, and introduces fresh outdoor air in via valves in
living rooms such as. living room, bedrooms and family room.
The cold outdoor air is heated via the high-efficiency counterflow heat exchanger by the hot exhaust air. The heat loss that occurs via
heat recovery, the built-in heat pump use to produce domestic hot water. All the energy in the exhaust air is utilized, and you have not
really seen any heat loss that you experience with an ordinary ventilation unit. In case of high hot water consumption, there is a 1.5 kW
electric supplement heater in the hot water tank, which can also be used to heat the water.
In the winter, the built-in heat pump can heat the supply air up to 34 ° C, and thus contribute to heating the home. When the supply air
is heated, at the same time a little heat is deposited in the hot water tank and ensures a constant high hot water temperature.
The heat pump has a reversible cooling circuit, which means that the cooling circuit can be turned and it can cool the supply air in the
summer. Compact P2 can cool the supply air by up to 10 ° C in relation to the outdoor air. Due to the low air exchange, usually 1/2 time
per hour, it will not act as an air conditioning system. However, when cooling, moisture in the supply air is removed, which results in a
lower humidity in the home. The lower humidity means that it is easier to withstand a slightly higher temperature, which therefore pro-
vides good comfort in the home.
When Compact P2 cools the supply air, the energy is deposited in the hot water tank, and it can thus be said that "free" domestic hot
water is produced during those periods.
The energy-efficient and low-noise GEOthermal heat pump heats the home via floor heating or lowtemperature radiators. It retrieves
the energy from the earth. The heat pump has an electrical power supply to help it to function during very cold periods. GEO can cool
the home in the summer with passive cooling, either through the underfloor heating system or fan coils.
The GEO ground source heat pump can also be used to help produce hot water for domestic use, either by pre-heating the water in a
buffer tank, or directly in a Compact P2 hot water tank, if bought with a solar coil.
