The purpose of all of heating/cooling units is to create the desired indoor comfort at low energy costs.
A uniform plant associated with optimal control terminal units, leading to maximum efficiency.
The best generators as condensing boiler or heat pump will operate poorly if they are not irrigated by a good flow of that agent.Similarly, radiation issuer or induction, such as a cold beam, such as a cold beam will be of low efficiency, if not provided a good flow.
Therefore, the energy efficiency of a heating / cooling will be optimal if the installation is homogeneous and perfectly balanced: - Flows provided should be available to all terminal units in full load; - The differential pressure regulating valves should not vary too much; - Flows should be compatible with the interfaces between systems.
For a complete uniformity, the entire system should be balanced, without forgetting anything: boilers and cooling groups, the interface between production and distribution circuits, control circuits and power emissions of terminal units. If all flows are correct, then the installation can be controlled easily.
An optimal solution for balancing and fine tuning of terminal units is the valve TBV-CMP, introduced by the company TOUR & Andersson.
In this game are taken several factors: - Comfort requirements; - Energy requirements; - Hydraulic uniformity; - Control equipment cost; - Installation and commissioning costs.
This solution is recommended when loads are sufficient to stabilize the pressure differential around the terminal unit.
Features: - A correct adjustment feature of this solution and an integrated differential pressure adjustment, contributing to a linear flow characteristic for optimal uniformity, simplifying the commissioning of the plant; - A release of differential pressure adjustment system allows a simple cleaning and maintenance and a quick installation; - More connection positions for easy installation; - Simply Connection to a driving system M30x1,5; - Stop function to simplify plant maintenance; - Variable adjustment; - Temperature range: * Minimum -20 degree C * Maximum +120 degree C - Flow range: * 15-125 l / h - for DN15LF * 75-135 l / h - for DN15NF * 125-630 l / h - for DN20NF * 255-1270 l/ h - for DN25NF - Dimensions: DN 15 - 25; - Pressure class: PN16; - Differential Pressure (dp): * Minimum - 15 kPa * Maximum - 350 kPa
