Special Offer Panasonic Counter Flow Ventilation VENTX 40V

Description PAW-VENTX–V is a ventilation unit complete with a heat recovery exchanger cell which is dedicated to changing air without wasting energy. The unit is particularly suitable for single family units, flats and in all cases where the nominal flow rates for air exchange do not exceed 380 m³/h. The unit is designed for installation inside buildings protected from the weather in a vertical wall position with ducted air distribution. Counter flow ventilation units are equipped with two fans to supply and extract air. A cross-flow heat exchanger recovers the energy contained in the extracted air and transfers it to the supplied air. This significantly reduces the building’s energy consumption, while at the same time keeping a good quality of the indoor air. The PAW-VENTX range is a fixed speed controlled unit, these models are recommended by us for Renovation projects only. Structure: self-supporting sheet metal frame, interior in high density EPS 30 kg/m³ and polyethylene foam. Carpentry and internal plugging in thick galvanised sheet metal. counterflow type: sensible polypropylene version Brushless fans: DC fans regulated by inverters allow high levels of comfort and energy efficiency with constant flow function. Filters: EPM1 filter on fresh air and extract air with low pressure drop. Easily removable for routine maintenance. Models: 2 sizes with different flow rates are available. PAW-VENTX-30V PAW-VENTX-40V Configurations: the unit is configurable in air flows according to the position of the room side and the outdoorside.• A factory configuration• B configuration modifiable on site Vertical Unit Airflow nominal: 266m³/h Airflow Maximum: 380m³/h Dimensions HxWxD: 590 x 576 x 795mm Weight 38kg *Requires Controller* Digital Controller for Panasonic Counter Flow systems(PAW-VENTX) 3 position fixed speed conroller (no accessible adjustment)

Airflow Geothermal Kit

Airflow Geothermal Kit Product Part Number Airflow Geothermal Kit - AFGEOTHERM Description The Brine to Air Exchanger enhances the thermal efficiency of your MVHR unit by provided additional preheating to your unit during the winter and also helps to cool the air during the summer. The Brine to Air Exchanger uses the warmth in the ground to maintain the brine’s temperature of 8 - 12°C. A 1.2 m deep flexible polyethylene under-soil tube pumps brine through a loop. To increase the heat exchange the tube should be laid directly under the soil in a sand bed. The minimum space between the parallel tubes should be 0.5 m. Alternatively to laying the tube horizontally a vertical bore can be used. Operation Brine to Air Energy collector can work either in automatic or manual mode. In automatic mode operation of the circulation pump is controlled by the MVHR unit. The pump circulates the brine when the outside air temperature falls below 5°C or when actual supply air temperature is higher than the set value. System can be switched into the manual mode by using an operation switch. In this mode the circulation pump is always turned on regardless of the outdoor air temperature. Installation Brine to air heat exchanger is mounted in-line before mvhr unit. It is important that the air flows through the heat exchanger in horizontal direction. To provide optimum performance it is recommended that approx. 1m of straight duct is mounted upstream and downstream of the brine to air heat exchanger. The ducting should be done with Airflex ISO system to avoid creation of the condensation. Alternatively insulated spiral ducting can be used. Pipework and connection between hydraulic kit and brine to air heat exchanger shall be provided on site. The pipe connections of the hydraulic kit are ¾” IG. The quick vent valve must be installed at the highest point of the pipework. It is recommended to install undersoil tube when outdoor air is above 5°C. The area where the undersoil tube is laid should not be built over so it is guaranteed that seeping rainwater can contribute to the thermal regeneration of the soil. The filling of the system is carried out via feed and drain cock located on the hydraulic kit. During this operation take care to avoid air entering the system. After the installation of the undersoil pipework, system should be tested at high pressure for tightness check. How does a brine Geothermal system work A network of brine (salty water) filled pipes are buried at a depth of approx 1.5 meters and connect to the air intake of a heat recovery ventilation system via a heat exchanger. The geothermal ducts use the energy stored in the ground. At a depth of 1 - 2 meters, the ground temperature in the UK varies between +8 and +12 ºC depending on the season and on the soil type. By using the relatively stable temperature at this, the efficiency of the ventilation system is greatly improved This provides a source of heating or cooling for a building. As an example, if in the winter months the outside temperature is -5ºc, the ground
