ETK6500

UTILIZE ALL ENERGY

ETK6500 exhaust air heat pump utilizes the energy of the warm ventilation air that is generated partly by the heating system, and of all other sources of heat in the house, such as electronics, people, solar radiation, and all other waste heat that would otherwise be lost.

The recovery of 100% of the energy generated in the house is the benefits of a high efficiency exhaust air heat pump. The energy recovery is always effective regardless of outside temperature, unlike other types of heat pumps which lose power the colder the outside air becomes. An ETK6500 always has 20° C air to extract energy from, independent of outside temperature. Therefore, it provides full power under all operating conditions.

Save up to 65% energy, regarding to tests made by the Swedish Energy authority, Energimyndigheten.

FUNCTION

ETK6500 is installed in houses with mechanical ventilation. The efficacy rate is suitable for houses with a living area of approximately 160-220 sq.m.

ETK6500 supplies the house with both heating and hot water. Fresh air is taken into the house through vents in exterior walls, grilles on the windows or other diffusers. Also a supply air unit, which is preheated by the heat pump, may be an option. Used exhaust air is vented through the house's duct system.

The room temperature exhaust air passes through the heat pump evaporator to ensure that all waste heat from the heat pumps electrical components has been taken. Through this efficient and well-dimensioned evaporator, maximum heat energy is received so that energy is transferred back into the heat pumps refrigerant circuit.

The now substantial refrigerated and consumed air is relegated outdoors. With an oversized custom scroll compressor the energy is regained to the water circuit in the house through the condenser. The steering in ETK6500 then controls a valve to either heat or hot water radiators, under floor heating, convector radiator or a combination of these.

After the compressor has indicated the maximum energy, at very cold weather and torrential filling of hot water, the comfort of living is then assured by further electrical output which is switched on in small steps when needed. In small houses with low energy requirements, these contributions will never be used.

ETK Function

Speed control

ETK6500 has a variable speed scroll compressor, which follows the necessity of heating in the house. The control of the ventilation fan is also variable speed driven, so that exactly the right air flow can be set. The customized computerized control of the heat-demand signals from the indoor temperature-sensor will influence the compressor to work under the best possible operating conditions.

ADVANTAGES

Some advantages with ETK exhaust air heat pumps, in addition to the simple installation, is that they also provides legionella safe water, reduces radon risk and reduces mold problems. ETK exhaust air heat pumps are lower and quieter than similar products on the market. If the ceiling is particularly low, the ventilation connections can be mounted on the side of the heat pump. You can choose whether you want the heat pump to be in brushed aluminium or have a white finish.

QUALITY ASSURANCE

Every ETK6500 exhaust air heat pump is produced individually by qualified refrigeration technicians.

Each heat pump is factory tested for at least 12 hours in well thought out programs before delivery.

Tested by the Swedish Energy Authority, Energimyndigheten.
