Independently managing flow rates Any system that has a heat pump as its energy source would benefit from installing an automatic dynamic balancing valve. By accurately managing the flow rates throughout the heating circuit using a flow-settable, pressure-independent, thermostatic radiator valve (TRV), an installer can optimise their design and ensure each part of the system receives the correct amount of energy independently, increasing the working life of the compressor within the heat pump. In addition, any hydronic circuit serving a secondary system must be balanced, meaning that they must be constructed in such a way as to guarantee the design flow rates of the thermal medium. Due to this, specific balancing devices are required depending on the varying system types and appliances used. WHAT IS THE DYNAMICAL® TRV? The DYNAMICAL® thermostatic radiator valve allows automatic dynamic balancing and pressure-independent adjustment of the heating system. The device, in conjunction with thermostatic, electronic,
or thermoelectric control, combines different functions in a single component. The valve can balance the heating system automatically, ensuring each terminal receives the set flow rate. Even in the case of partial circuit closure, employing the regulating valves, the flow rates in the open circuits remain constant at the set value – a vital feature when being installed on systems powered by heat pumps. By using the DYNAMICAL® in combination with thermostatic control heads, the surrounding temperature can remain automatically constant, guaranteeing effective energy saving.
PROTECTION FOR EXPOSED INSTALLATIONS WITH ANTI- FREEZE VALVES Fitting an anti-freeze valve is the best method of preventing a heat pump from freezing. The Altecnic 108 Anti-Freeze Valve, for example, can be fitted onto an existing heat pump and uses a dripping technique to prevent the system from freezing over.
HOW DOES THE 108 ANTI- FREEZE VALVE WORK?
The valve itself is designed to be installed in the flow and return pipework from the heat pump and installed on the external pipework. By opening at temperatures below 3°C, the valve allows system content to be dripped/discharged safely, preventing the system from freezing. At temperatures above 4°C, the valve then shuts again to stop unnecessary draining. With the valve designed specifically for heat pump installations, Caleffi has ensured it is compact and easy to install, whilst remaining a top-quality product.
GETTING THE MOST OUT OF YOUR HEAT PUMP INSTALLATION
With no room for damage, the installation of a buffer tank, anti-freeze valves and automatic balancing TRVs protects the end user’s investment and the installers’ hard work. Given the installation costs of renewable technologies compared to standard gas or oil installations, the benefits of a relatively small outlay to protect this investment are clear.
