5 Sizing Expansion Automats Basic Concepts for the Calculation of Expansion Automats To select the right expansion automat it is necessary to understand the following principles: Static height This is the height of the system between the connection of the Flexcon expansion appliance and the highest point, measured in water column metres (1 wcm = 0.1 bar). System water capacity This is the total volume of water in the entire system including heat source, radiators, pipe work etc. Increase in water volume (in %) The table below shows the percentage volume increase of water as temperature increases from 10 C to 110 C. Expansion volume The expansion volume is determined in the following way: expansion volume = capacity x increase in volume at the average heating temperature. Increase in temperature [ C] Increase in volume [%] Increase in volume [%] Temperature [ C] Flexcon M-K Compressor Curves Flexcon M-K selection graph.

6 Pressurisation and Expansion Automats Example: heating temperature 90/70 C (average 80 C) =.89%. Heating/Cooling power This is the sum of the nominal heating capacities. Capacity of the expansion automat The capacity of a pump expansion automat is determined in the following way: capacity of expansion appliance = 1.3 x expansion volume (in the case of the Flexcon M-K / C the factor is 1.4). The factor of 1.3 is based on the following assumptions: The expansion vessel has to hold at least 10% more than the calculated expansion volume. The volume of the vessel allows for refilling and min./max. levels. Corrections to tolerances which, according to various standards, are admissible for parts of the system.

9 Flexcon M-K/U, the reliable compressor expansion automat The Flexcon M-K/U compressor expansion automats store the expansion water from the system. They also hold the system pressure at the pre-set level within clearly defined limits. Water and compressed air are separated from each other by a removable high-quality butyl-rubber bladder which has a high diffusion density (low gas permeability). Noticeable features of the Flexcon M-K/U are the high level of reliability and sturdiness. The Flexcon M-K/U is adaptable to a wide range of situations and there are plenty of optional accessories which mean that it can be put to many different uses in countless systems. They are low-noise compressors that require no oil. The entirely micro-processor driven control unit in the Flexcon M-K/U expansion automat has a number of parameters that can be set to any variable within a given range. The benefits of the Flexcon M-K/U Stable system pressure and a large working vessel volume. With red epoxy-powder coating. Easy to install and commission. Intuitieve SPC controller. This is a 'plug and play' control system including clear instructions via the sensor touch screen, intuitive and easy to use with economic energy-save mode. FLEXCON M-K/U 1. Cold The automat contains a small amount of water. The automat is at rest.. Warming up The volume of water, and thus the system pressure, increases. The controller responds to this by discharging air from the vessel and, as a result, the expansion water flows into the bladder. 5 Product overview 013 We reserve the right to change designs and technical specifications of our products.

Foot-height adjuster for leveling. /capacity sensor. 3. Full power By storing increasing amounts of water in the vessel the controller keeps the system pressure at a constant level. When the system has warmed up completely, the vessel will be almost full to capacity. 4. Cooling down When the volume of water and thus the system pressure decreases, the controller will respond by increasing the airpressure in the vessel with displacement of water back into the system as a result. This restores equilibrium in the system pressure. Product overview 013 We reserve the right to change designs and technical specifications of our products. 53

17 Tomorrow's Technology in Today's Flamcomat The Flamcomat is a modern, pump-driven pressurisation unit. Thanks to its sophisticated construction we have made it possible to incorporate important functions into one compact unit. The Flamcomat consists of a pump unit and a pressureless vessel. This modular expansion system can be expanded with additional vessels and accessories from our comprehensive range. In this way we can tailor the equipment precisely to the needs of your system. The Flamcomat is suitable for any size of heating installation and for both refrigeration and airconditioning installations. The Flamcomat makes sure that the system pressure remains within precise limits and that the system is topped-up automatically should there be any requirements. The venting process is incorporated, dynamic and energy-efficient. Flexvent Super floatvent with air-intake preventer. Steel vessel at atmospheric pressure. Flexible hoses. Lockshield ball valves with drain. Single or double pump configuration. Touch pad control panel. Top-up hose. FLAMCOMAT GB Benefits of the Flamcomat The Flamcomat combines pressure-control unit, dynamic de-aeration and topping-up all in one. Choice of a range of pump modules.

20 bar bar Pressurisation and Expansion Automats How the Automat Works 5. Topping-up If the water level in the vessel drops to a critical level, an appropriate amount of water will be carefully pumped into the system from the water mains. This water will be de-aerated (by pressure loss and the PALL rings), before entering the vessel. 1. Cold The automat contains a small amount of water. The automat is still at rest.. Warming up The volume of water and the system pressure increases. The unit responds to this by opening the solenoid valve. Water flows into the pressureless vessel. The water in the vessel is de-aerated due to both the drop in pressure and the presence of the PALL rings. 4. Cooling down The volume of water and the system pressure decreases. The de-aerated water is pumped from the pressureless vessel back into the system. This restores the system pressure Full power When the system has warmed up completely, the vessel will be almost full to capacity C Product overview 013 We reserve the right to change designs and technical specifications of our products. 63

21 FLAMCOMAT - PUMP UNITS For heating and chilled water (cooling) installations. Flamcomats with pump units are used for storage of expansion water, de-aeration and topping up your installation automatically as an integrated controlled unit carried out with state of the art micro-electronics. The easy to use, detachable control unit shows all system operation and fault conditions clearly and conveniently. The control unit can also be used remotely, up to a distance of 500 metres, so that you can view the system from your workstation and may be interfaced with external systems to give a networked control and alarm system. By using Flamco-patented PALL-rings, gas bubbles down to a size of 18 microns can be removed from the system. The PALL-rings have a large adhesive surface, which means that the Flamcomat can eliminate large and small air bubbles from your system. This is described further in the independent research report commissioned from the Technical University of Delft, the Netherlands, which can be obtained from Flamco.
