Demand Control Ventilation Systems

Driver Renweables supply and install of DCV Equipment in Cork, Limerick and Kerry. (DCV) is a method of providing automatic regulation to the ventilation system depending on the requirements of the building and upon the needs of air change rates number of occupancy, pollution loads, general environmental factors. Demand Control Ventilation a suitable sensor and without user intervention.

Sustainable Energy
This approach can be applied to any of the system types above and has been very popular in Europe for decades. Demand Control is now a common feature of quality s continuous mechanical extract ventilation and passive stack ventilation systems.

Our Demand Control Ventilation systems, extract and supply air flow rates. These can be regulated to ventilate where and when needed, achieving an overall reduction in air renewal and associated heat losses.

Recent studies carried out in Europe demonstrate that DCV results in at least 30% reduction in ventilation losses compared to natural ventilation with conventional extract fans. It can also reduce the primary energy use of associated fans.

Extensive monitoring also shows that demand-controlled mechanical extract ventilation achieves excellent indoor air quality leaving your house fresh all day.

Benefits of DCV

  •  Low electrical running costs (from 0.27-0.5 W/l/s).
  •  No filter changes.
  •  Silent operation.
  •  Continuous demand driven extract ventilation.
  •  No occupier interface required.
  •  Humidity sensitive strips with 30 year guarantee.

The results with DCV is a system that is comparable in efficiency to heat recovery, cost effective and simple, but most importantly, quietly monitors and manages air quality. DCV is not constrained by air tightness levels, so it is suitable for all house types and all ages, new builds and commercial unit to hotels and privately owned dwellings in Cork, Limerick and Kerry.

Should you install a heat recovery ventilation system onto your new home?

By installing heat recovery ventilation systems, you can block up those 6″ holes and let our fans quietly and constantly ventilate your home, while extracting any excess heat from the exhaust air from kitchens and bathrooms.

Where most people notice the benefits of the heat recovery ventilation system, is after a shower, as our unit will automatically boost the extract airflow to help clear the bathroom faster.

Its great for removing odours after cooking or after there has been high occupancy in the house or people have been smoking. In the mornings some bedrooms can smell stale and you need to open the window to ventilate the room.

With the Heat Recovery Ventilation (HRV) system installed, bedrooms are fresh in the morning and the house doesn’t smell after you host a dinner party because when you were sleeping, the system has been working to remove all the stale smells and replace the air with fresh, filtered and heated outdoor air.

Fresh filtered air is drawn into living spaces such as bedrooms and living rooms, providing continuous ventilation even when the house is sealed up for the day. By keeping humidity levels low and introducing warmed fresh filtered air to replace contaminated air, the quality of the internal environment is significantly improved. You can actually feel the freshness in the air within the house.

Continuous whole house ventilation can help reduce relative humidity to below 70% RH, which inhibits the ideal living and breeding conditions of the house dust mite.

The Kinetic heat recovery ventilation unit can be used with a wide range of Vent-Axia controllers and sensors. Ranging from remote controllers to wired remote sensor that can control your indoor air quality and letting your home breathe.

Very high Seasonal Efficiencies

Seasonal efficiency belongs to top of the class. The SCOP is a way of showing how effective the heat pump is in heating mode in all over Europe. There are three different climate zones in Europe according to the testing and accordingly three different Seasonal data, so be sure that you check the SCOP to your climate zone.The Nordic countries belong to the cold climate (cold/C), apart from Denmark belonging average climate (average /A).

Large parts of eastern are also in the cold climate zone. Ireland is in the warm climate zone. Seasonal efficiency gives an idea of the heat pump’s efficiency over the entire heating season with varying outdoor temperatures and is an important parameter for the purchase of a heat pump. AA 5.5 Performance has SCOP A of 4.7 and SCOP C 3.7. In practice this means that savings of this heat pump is extremely high, and few if any heat pumps has a shorter payback time

Heat Pumps Installation

Heat Pumps Supply Installation Cork Commercial and Domestic Limerick Kerry

Heat Pump installation Kerry, Cork and Limerick

Heat pumps extract the warmth from solar energy which is stored in the ground, water courses and in the air. The systems use electricity to drive a pump which extracts the warmth and upgrades it into useful heat. Fridges are heat pumps and work by the same principal but in reverse, moving heat from inside the fridge to outside, providing cooling for the inside.

There are 3 main options; Air Source Heat Pumps, Ground Source Heat Pumps and Water Source Heat Pumps.

Driver Renewables supply and install heat pump to all business and public sectors.

Air Source Heat Pump
With air source heat pumps a fan draws air in to the unit and this flows over a closed loop of coiled piping circulating a fluid (either a mixture of water and anti-freeze or brine) which extracts the heat from the air. Air to water systems then use the heat to provide for central heating systems. Air to air systems mostly use fans to circulate heat into the property, but don’t produce hot water.

Ground Source Heat Pump
A ground source heat pump extracts heat from the ground by circulating a fluid through a closed loop of underground piping. This fluid absorbs the heat stored in the earth and carries it to the heat pump in the building.

Water Source Heat Pump
Water source heat pumps extract heat from a local water source and usually operate exactly like ground source heat pumps with a fluid pumped around a cyclical “closed” system. However, some systems are “open” and involve water being pumped out of the ground from a borehole and discharged via a heat exchanger to a river or sewer.

Combining Heat Pumps with Solar Energy
Heat pumps, being powered by electricity, are the perfect renewable energy partner for Solar Photovoltaic Panels (a method for generating electric power by using solar cells) as any free energy generated through solar power can be used to heat your home, so with careful use a heat pump and solar PV system in your home could mean an end to heating and electricity bills.

Heat Pump AWH V5+

AWH V5+

All air source heat pumps operate under the same general principles.

However the differences in quality, technology and application vary drastically.

The new AWH V5+ series exhibits a number of cutting edge, technological and practical advances to create a comfortable living environment.

Nordic Style

The AWH V5+ series has been designed to fit in with the aesthetics of the modern home. The V5+ series comes with a grey powder coated metal housing, stainless steel cover and black coated grills and fans. These measures greatly improve the appearance of the unit but also serve to protect the longevity of the unit.

LEN Start Technology

The V5+ series contains our latest LEN technology. This technology allows the unit start the compressor and fan at their lowest setting. This technology prevents surges to the electrical system of the dwelling and reduces the noise of the unit.

DELA Design

The V5+ series represents the latest advancements in heat pump technology.  This series of heat pumps is of split design – DELA. In standard monoblock units the heating water for the dwelling flows through the outdoor unit where it is heated.

With the DELA design the heat generated by the outdoor unit is delivered to the indoor unit in the medium of refrigerant gas 410A. The heat energy in the gas is then transferred to the heating water in the indoor unit. This format greatly increases efficiency, especially in colder weather conditions and deicing cycles.

LÅG – Low Temperature

The efficiencies of heat pumps are maximised at lower temperatures. When they are utilised to generate high temperature the efficiencies drop dramatically especially in colder weather conditions.

This often results in the use of electric heaters and / or increased electrical bills. The V5+ series is a low temperature heat pump with its flow restricted to 48°C. With modern houses utilising underfloor and aluminium radiator heating the preferred flow temperature range is 30 -45°C.

For hot water generation we use the HEMERA hot water unit, which is specifically designed for hot water generation. This maximises the real life efficiency of the system.

AVISA Cycle

Condensation often forms and freezes on the outdoor heat exchanger of a heat pump. This prevents air flow through the exchanger and so must be removed through a cycle known as defrosting.

Traditional defrosting cycles utilise the stored heat within a buffer or electric element to deice the unit steeling heat back from the dwelling and increased electrical consumption.

The V5+ series has a bespoke, proactive defrosting cycle, AVISA. An outdoor sensor on the heat exchanger indicates the beginning of freezing and before excessive ice builds up the AVISA cycle begins.

The AVISA cycle simply diverts hot gas around the heat exchanger, clearing the build up in moments and allowing the unit to revert back to providing heating.

Back Up Heather – Immersion

Immersions are often used to provide high temperature hot water, supplement the heating system and/or during defrosting cycles.

The V5+ series is one of the only heat pumps without an integrated electric heater.

At ES we believe that a truly efficient product, which has been developed to the highest of standards should not require boost or back up from additional heaters.

AWH V5+ Seamless Modulation

The V5+ series heat pump incorporates the latest inverter technology.

This technology allows a heat pump to match its output to suit the requirement of the dwelling.

The inverter technology continuously monitors the heating requirement of the dwelling. As the heat demand increases and decreases, the inverter increases the units output accordingly.

This technology drastically reduces energy consumption and creates an optimum living environment.

AWH V5+ also has Climate Adjustment Technology and works In conjunction with Seamless modulation the V5+ series

AWH V5+ Climate Adjustment technology

This technology works by increasing and decreasing the heat pumps flow temperature according to external temperatures.

The minimum and maximum desired flow temperatures are entered into the unit and the unit will control the flow temperature for the system based upon external, internal and desired temperatures.
