Heat pumps heat and cool with renewable energy from nature

This brochure provides detailed information about sustainable and environmentally responsible heat production using heat pumps from Viessmann. Heat pumps utilise renewable energy from the ground, groundwater or the air. They lower consumption of fossil fuels, conserve valuable resources and reduce CO2 emissions that damage the environment.

By using this technology, system users benefit from a further advantage: some Viessmann heat pumps also feature active and natural cooling functions. Alongside their classic application as heat sources on cold days, they can also create a pleasant room climate in summer by bringing refreshing cool air into the house.

The extensive product range offers the right heat pump to suit all requirements. Even at the planning stage, structural and geological conditions, as well as personal and individual preferences concerning heat demand can be taken into account. What’s more, this isn’t just suitable for new build. Viessmann heat pumps can be used equally well in modernisation projects, operated with solar thermal systems or combined with an existing oil or gas heating system to form a multi mode system.

Simple principle, great result

A heat pump works in a similar way to a fridge – simply the other way round.

In a fridge, heat is transferred from the inside The gas created is compressed by the scroll to the outside. With a heat pump, this compressor, which causes it to heat up. The happens exactly the other way round. Heat gas heated in this way transfers its heat via from the air or the ground is transferred the condenser to the heating water or DHW into the living space via the heating system. heating system, and thereby condenses Vapour from a refrigerant is compressed to again. Finally, the refrigerant, which is still increase the temperature, to make it high under pressure, is expanded in an expansion enough for central heating and DHW heating. valve, and the circuit begins again. In this process, the Vitocal 350-G reaches up to 72 °C; the Vitocal 350-A up to 65 °C. A heat pump can make use of the These heat pumps can therefore also be following energy sources: used for modernisation as they can provide a sufficiently high flow temperature for central „ Air – practically unlimited availability; heating with radiators. lowest investment costs „ Ground – via geothermal collector or Highly efficient scroll compressor geothermal probe; very efficient The compression process is vital for „ Water – extremely efficient; observe the efficiency of a heat pump. For this, water quality Viessmann uses a Compliant scroll „ Waste heat – subject to availability, volume compressor. It is characterised by quiet and temperature level of the waste heat operation, low vibrations, low maintenance and an extremely long service life. The best heat source for each individual case depends on local conditions and the actual To generate heat, for example, heat is heat demand. extracted from the ambient air and used to evaporate a refrigerant that boils at Seasonal performance factor low temperature. The coefficient of performance (COP) is the ratio of the heat transfer to the power consumption. The seasonal performance factor is the average of all COPs occurring in a year. Heat pump VITOCAL 300 The coefficient of performance is used to compare heat pumps with regard to efficiency, yet it only applies at a certain operating point under defined temperature Compression process conditions.

For planning (for example, to be able to 55 °C specify the consumption costs arising from using a heat pump), it is necessary to consider the heat pump operation over the whole year. For this, the heat volume transferred over the year is given in relation to the overall electrical Ground power drawn by the heat pump system over temperature all year round between 5 and 18 °C (at 2 m depth) the same period. This includes the amounts of power used by pumps, control units, Getting hotter towards the centre – from an initial etc. The result is given as the seasonal temperature of between 5 and 18 °C, a flow temperature performance factor. of up to 72 °C is achieved. 8/9

No-one would turn on the central heating on Natural cooling – naturally a hot summer day. With a Viessmann heat While the ground or groundwater is used pump, the situation is different, as some in winter to provide energy for heating, in types offer an additional cooling function. summer it can be used for natural cooling. With the natural cooling function, the control Active or passive cooling unit only starts the primary pump and heating Cooling operates according to two circuit pump. This means the relatively hot different methods: water from the underfloor heating system can transfer its heat in the heat exchanger to „ Passive cooling: the brine in the primary circuit. This extracts This is where the brine medium or the heat from all rooms that are connected, which groundwater absorbs the energy from the makes natural cooling a particularly energy heating circuit via a heat exchanger and efficient and affordable way to cool buildings. transfers it outside. This function is also called natural cooling, as it uses the natural ambient temperature. Apart from the control unit and circulation pump, the heat pump remains switched off.

„ Active cooling: For this, the function of the heat pump is simply reversed. This method of cooling can be described as "reverse operation". This means that the refrigerant circuit is reversed internally or reversal is achieved by an external changeover of the primary and secondary circuits. As with a fridge, cooling is then actively generated by the heat pump. NC-Box Optional equipment for Viessmann heat pumps to provide passive cooling Page 60

AC-Box Optional equipment for Viessmann heat pumps to provide active cooling Page 61 Natural cooling NC-Box

Energy efficient and affordable cooling Everything you need to keep cool with the NC-Box In the Viessmann "Natural Cooling Box", all The Viessmann NC-Box helps heat pumps to components are prefitted. This makes the provide cooling in a completely natural way. thermally insulated box not only compact, In fact, it's really quite simple. On hot summer but also particularly simple and quick to install. days, the temperatures inside the house are higher than those in the ground or With or without mixer groundwater. The heat pump control unit Depending on the sort of cooling needed, the then switches to natural cooling, and uses natural cooling box comes in two different the ground or groundwater to dissipate the versions, either with or without mixer. The heat from your living space. integral mixer enables continuous operation without falling below the dew point. Saving while cooling The natural cooling function does not use all the technology of the heat pump. This means that, apart from the control unit and circulation pumps, all other functions remain off. Only a very small amount of power is therefore consumed for operation, This makes natural cooling a particularly energy efficient and affordable method for cooling buildings.

The effective thermal insulation of the NC-Box prevents the formation of condensate. Active cooling AC-Box 60/61

The AC-Box efficiently combines heat- Keep cool when it gets really hot outside ing and cooling With active cooling, the compressor The Viessmann AC-Box combines active and circuit starts to work. However, it does not natural cooling in the heat pump systems, provide heating – the internal control unit, in thus making them even more versatile and conjunction with the AC-Box, reverses the convenient. Depending on the required output and input functions to actively transfer room temperature, the system changes over heat out of the building to the geothermal automatically. If only a low cooling capacity probe. Cold water then flows through the is required, natural cooling is sufficient. But heating circuit itself – cooled down to 7 °C if that is no longer sufficient, active cooling if required. is added. Utilising extracted energy Cooling using tiny amounts of energy Incidentally, direct use can also be made With natural cooling, the compressor circuit of the heat transferred out of the rooms in is not needed. Only the brine and heating this way, for example for DHW heating or circuit pumps are operational and utilise the to heat a swimming pool. This means temperature differential between the rooms cooling and heating functions can be and the ground or groundwater. In this way, combined extremely effectively. rooms can be cooled very cost effectively.

Well developed technology: The AC-Box (to the left of the heat pump) simply starts the relevant heat pump function – either the active or the natural cooling, depending on the required cooling capacity. Domestic ventilation Vitovent 300 system 62/63

VITOVENT 300

The Vitovent 300 ventilation system creates a pleasant, healthy atmosphere in your room, without wasting energy.

Air quality makes a real difference to the Flat duct system for quick assembly quality of life inside the home. For this For the Vitovent 300, alongside the already however, an adequate air change rate is familiar accessories, the new, flexible, plastic essential. However, modern construction flat duct system can be used, which is quick practices do not make this easy, as buildings and easy to install. Its low height enables are designed to be as airtight as possible, an integration of this duct into ceiling/floor to prevent heat loss. The Vitovent 300 structures and can be subjected to ventilation system offers the solution, mechanical loads. The conventionally applied enabling a pleasant, healthy climate in sealing with cold shrink tape is not required. the room. The smooth anti-bacterial surface coating ensures permanently hygienic air handling.

Air is considered to be fresh when its CO2 A silencer is already integrated in the concentration falls below 0.1% by volume and distribution box. it is free from odours. People usually open the windows to allow fresh air in. However, window ventilation is not particularly reliable. If windows are left open for too long, heat is wasted; not long enough, and tiredness results. In contrast, the Vitovent 300 domestic ventilation system continuously replaces the air and removes odours and noxious substances. The result is a pleasant, healthy climate.

Prevent mould, protect the building fabric One of the main causes of mould growth is humid indoor air. Mould can be unhealthy for the occupants and will cause permanent damage to the fabric of the building. From this point of view alone, investing in a domestic ventilation system is cheaper than remedying building damage caused by Air distribution box fungal growth and mould.

Enjoy security and quietness Vitovent 300 ensures a continuous air change – so windows can stay closed all year round. That doesn't just offer improved safety against burglary, but also keeps out any noise there may be outside.

Ventilating virtually without energy loss Energy saving is the trump card of the Vitovent 300. The powerful heat exchanger recovers up to 92 percent of the latent heat contained in the stale air and uses it to heat the incoming air. Thanks to the very efficient DC motors, for each kilowatt hour of electrical energy expended, 15 times more heating energy is recovered. This means that, for example, around 300 litres of fuel oil could be saved in a year for a living area of 150 square metres.
