Airflow Geothermal Kit

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

Vent Axia Kinetic 300ZH Heat Recovery Unit

Vent Axia Kinetic 300ZH Heat Recovery Unit

Vent Axia Sentinel Kinetic 300ZH Horizontal Heat Recovery Unit Product Part Number Vent Axia Sentinel Kinetic 300ZH - 449536 Filtration 2 x G3 with optional F5 Controllability The Lo-Carbon Sentinel Kinetic Horizontal models have three fully adjustable speeds and a purge setting (maximum airflow). Supplied with the unit is a digital controller that can be used to pre-set the speeds to any required airflow within the performance range. Boost can be achieved with almost any type of sensor or switch including momentary. Integral Humidity Sensor The integral humidity sensor increases speed in proportion to relative humidity levels, saving energy and reducing noise. The sensor also reacts to small but rapid increases in humidity, even if the normal trigger threshold is not reached. This unique feature ensures adequate ventilation, even for the smallest wet room. The night time relative humidity setback feature suppresses nuisance tripping as humidity gradually increases with falling temperature Construction Fully insulated construction of galvanised steel. Motors The unit has 2 x low energy, high efficiency EC/DC motors Installation The Sentinel Kinetic Horizontal models designed to be horizontally mounted under a slab, with access for servicing and maintenance from below. When mounted in an unheated area ducting must be insulated. The Condensate drain is through the 'atmosphere' end of the unit. Using the fittings supplied, the final condensate connection is made outside the unit and can be completed after installation. Electrical and control connections are also made on the outside of the unit. Accessories In addition to a choice of compatible ducting systems a full range of controls, sensors, in-line silencers, floor/wall/ceiling inlet and outlet diffusers are available to complete the installation.
