The Importance of a Balanced System? Balancing valves are essential for any fully functioning cooling or heating water distribution system, incorporating chillers or boilers. When applied to the terminal, distributing and main lines, balance valves regulate the flow rate to meet design requirements.
An accurately balanced system provides the desired flow distribution through a building, saves energy and cost, and is trouble-free to operate and maintain. In short, it is the key to providing a comfortable indoor climate, or a steady supply of hot and cold water. Why Dynamic Balancing? The water flowing around any cooling or heating water system is essentially lazy.
It will always take the path of least resistance, leaving you with overflow closest to the pump and underflow furthest away from the pump. Dynamic balancing valves force the water to flow evenly to all areas at design flow rate. In a constant volume system, a constant volume of water is pumped around a system utilising three or four port valves, and diverted back to the plantroom if not required.
Hattersley Future Flow range includes a variety of dynamic balancing valves that use the latest technology to maintain the required design flow rate. In contrast to static balancing valves they are pressure independent so that flow rates remain constant, irrespective of any pressure changes within the system.
Water is lazy and will take the shortest route! Constant flow uses a straightforward and simple design that can be applied to a broad range of projects. This involves the use of a fixed-speed pump that is set to the maximum load of the system. In addition, double-regulating balancing valves are manually set to regulate the impact of pressure changes across the system. Although the capital costs of installing a constant flow system are relatively low, the manual balancing required is time consuming, complicated, laborious and system is inefficient.
This results in higher running costs and subsequently resulting in higher CO2 emissions. Since most air-conditioning and water distribution systems only reach peak load for limited periods, energy is wasted by continually running the pumps at a fixed speed. Inherently Very Stable Constant pressure drops in distribution pipework Constant pressure drops in circuits at part load. Why do we need Dynamic Balancing — Constant Volume? Constant amount of water pumped around a system controlled by three or four port control valves and would be;.
Because they are significantly more energy efficient than constant flow systems. This favoured method for heating and cooling systems uses inverter-driven pumps that operate at variable speeds to match the load. Double regulating, 2-Port motorised control valves are typically used to control flow to terminal fan coil units; in heating-only systems, a thermostatic radiator valve TRV is used to regulate flow to radiators.
The DPCVs maintain constant differential pressure across a sub branch. This protects upstream or downstream control valves depending whether installed on the flow or return, from the effects of both high pressure and pressure variations, which can be caused by the movement of control valves in other branches. Once a sub circuit has been commissioned, Hattersley DPCV protects the flow and balance from being affected by other sub circuits; this is referred to as a semi-automatic method of balancing the system.
Fully automatic balancing can be used in both variable and constant flow systems to enhance the performance of any HVAC system and save energy. As well as removing common problems caused by high and excessive system pressure — such as noisy valves — automatic balancing valves improves room temperature control. Inherently Very Unstable Dynamic pressure drops in distribution pipework Dynamic pressure drops in circuits at part load.
To enable modulation 2-Port control valves to operate with an acceptable authority, a DPCV is installed to limit the circuit pressure differential. The installation of DPCVs on sub-branches with 2-Port control valves is therefore essential to achieve good control. So what happens when the cooling load is satisfied? We now have our Variable Speed Pump, and inverter, but need other components to make it work efficiently. We need to remove the 3-Way valves, and replace with 2-Way valves.
When Cooling is satisfied, Thermostats identify this, and close the 2-Way valves. With the 2-Way valves closed, and pump still running the differential pressure increases. DPCVs were introduced specifically to deal with this problem. The Last Piece of the Jigsaw We now have most of the components needed. We began this session looking to improve Chiller Efficiency by maintaining a high return temperature.
We installed Variable speed pumps so that we can save energy by only pumping Chilled water when it is needed. We need Differential Pressure Control Valves to protect the 2-Way valves by responding to changes in pressures. Dynamic balancing makes fan coil units, chilled beams, air handling units and plate heat exchangers in variable volume heating and cooling systems more energy efficient. This solution uses a combination of valves such as a differential pressure control valve and double-regulating valve commissioning set and motorised control valve, when fitted with either v, 3-Point or thermal actuators, to create a dynamically balanced solution.
The use of dynamic balancing valves significantly reduces installation and commissioning costs. Because the triple control functions are matched for optimum system performance, and only one valve has to be mounted in the system. There are no high and varying pressure drops, which are common problems with traditional twoport control valves. Also, this integrated approach saves on space, which is important as room for valve installation in a terminal units is often restricted. Constant Flow Systems: Flow Regulating Valves Hattersley has developed a range of constant flow regulating valves that are designed to optimise water flow in heating and cooling systems.
These valves feature flow limiting, shut-off and adjustment functions, which automatically compensate for changes in pressure to maximise energy efficiency. They also reduce the time and cost of balancing.

Hence while putting the valves in the return the flow measured is considering the pressure drop in the coils also and therfore you will get the accurate water flow in gpm while water balancing. This is as per my limited knowledge. Hoe this would be helpful to you. Theoretically there is no problem whether to install control valve on either supply or return line. With a control valve on the return side, the water is at a higher pressure through the coil, reducing off gas, thereby lowering dissolved oxygen content. If it is a hot system, some manufacturers have temperature limitations on the actuators. If it is a cold system, it is always better to have less thermal breaks on the colder side e. The return side installation reduces sweating on the electronic actuator, which is more prone to failure when wet. The main reason to install DRV or to say double regulating valve on the return line is that the flow can be restricted or can be at a halt in the Fan coil unit FCU coil for a small amount of time this is very important as the heat transfer is efficiently used in overall we can say it restricts the flow to sense the temperature change according to the load and regulates the flow ,there is a term called by pass factor employed for calculating the heat load this is the same by pass factor which is to be kept used up and it is nothing but the area available for the air to pass over the coil to extract coolness from the coil. Just to control the flow such that there will not be any change in the pumping system.
