As per VDI 2035, heating systems must be filled with treated heating circuit water. In addition, high-performance heat transfer media and/or frost protection agents are increasingly being used. Regardless of whether a new heating system is installed or an existing one upgraded, flushing the system is essential to remove contamination and ensure efficient operation. This requires a filling and f lushing unit to be installed. For subsequent operation, the installation of a magnetite sludge separa tor is state of the art to ensure separation of contaminants such as magnetite on an ongoing basis. It is advisable to install shut-off elements to allow for easy cleaning the magnetite sludge separator. Practically all heat generators already feature electronic displays for the flow rate and system pressure. Nevertheless, a mechanical flow meter and a classic pressure gauge are helpful in monitoring the ini tial filling of the system and in checking the flow rate and system pressure during subsequent service work. Installing these components individually can lead to space problems. This often results in impor tant fittings being installed in a poorly accessible location, which makes them difficult to operate later on. Installing, sealing and insulating the individual components requires a great deal of effort. Finally, using individual components would result in an additional pressure loss in the complete system which can be avoided with AHS.
Function
The heat pump service combination combines all the functions of the individual components described in a compact unit and offers a practical solution covering the entire life cycle of the system:
During installation or maintenance, the combination can be used for flushing and filling of the system. The supplied hose connections are screwed on instead of the separator or filter.
During operation, the connections are used to accommodate the sludge separator or filter. Thanks to the integrated ball valves, both connections can be reliably closed for conversion, dismantling and cleaning. The flow meter provides information on the actual flow rate. An optional pressure gauge can be fitted from both sides, depending on the mounting position) to allow a quick visual inspection.
The form-fit thermal insulation pieces (accessories) optimally reduce heat losses and save time dur ing installation. The AHS 500 version with a brass filter with stainless steel sieve is available for high system temperatures.
