General
Quick facts
AQUA Link is a pioneering hydronic module designed to optimise connection between the chiller and the users in plants featuring both an air handling unit (for air ventilation and humidity control) and chilled beams (for ambient temperature control).
►► One single interlocutor for the entire plant eliminates possible inconveniences relating to identification of responsibilities and difficult communications with the various parties involved;
AQUA Link always produces and distributes the exact right amount of water at the exact required temperature to both cooling coils and for example chilled beams. AQUA Link contains all you need in a water circuit between a Swegon chiller and GOLD air handling unit. The former time-consuming and expensive process is now replaced with Plug and Play!
►► The system only requires hydronic and electrical connection between the chiller, the users and the AQUA Link to operate. ►► All equipment and components are condensed in one unique volume and AQUA Link can be placed outdoor. ►► Energy efficient through demand controlled operation and energy efficient pumps.

AQUA Link
Features and operating principle The hydronic module AQUA Link is designed to optimise connection between the chiller and the users in plants featuring both an air handling unit (for air ventilation and humidity control) and chilled beams for ambient temperature control (or other elements like fan coils for example). The control algorithm gives high benefits in terms of energy consumption, which is minimised through the control of several parameters at a time. These parameters are: temperature setpoint of chilled water produced by the chiller, pump rotation (both in primary and secondary circuits, if any), opening of the water flow control valves. Some additional benefits are granted at installation: the module, in fact, already features all the required elements, which consequently do not need to be provided for separately and are governed by one single controller. Temperature setpoint modulation The temperature at which chilled water is produced to the chiller (mix of water and glycol for glycol version and pure water for “No Glycol” version), that is directly connected to the refrigerant evaporation temperature, is essential for the determination of the energy efficiency coefficient of the chiller (EER or ESEER when considered in seasonal terms). In traditional plants where one chiller feeds both the air handling units and the chilled beams, the cold fluid is supplied at one temperature only (typically 7°C) and is blended with the fluid returning from the chilled beams so that the correct water supply temperature is guaranteed. Actually, the production of fluid at such low temperature is not always required. Consider, for instance, that the correct water supply temperature to the chilled beams is normally around 14°C: forced dehumidification is not always necessary in air handling units, especially in climate conditions such as those in Northern European countries, and free cooling may be adopted frequently.
increase in the chiller energy efficiency. The variable chiller setpoint and continuous transfer of operating parameter data between the controllers on the users’ side and the chiller keep the fluid production temperature as high as possible and, in any case, such as to fully meet the users’ requirements. This operating logic offers a substantial benefit in terms of energy consumption minimisation thanks to enhanced chiller operating efficiency. Water flow rate modulation The amount of energy used to pump the fluid is linked to the flow rate required by the users. A decrease in the amount of pumped water causes a proportional reduction of the energy spent for this purpose. The water flow rate required to the users basically depends on the water load to be supplied. This is substantially variable according to, for instance, the number of chilled beams to be fed against the total number of chilled beams installed, which need to be served in full load conditions. The water flow rate is modulated, and energy consumption for pumping is consequently reduced, thanks to inverters and variable pumps which are operated by a pressure signal detected by a probe fitted in the hydronic piping. 2-way valve opening modulation The primary circuit features two 2-way valves that control the destined flow to the AHU and to the plate heat exchanger (or mix manifold for “No Glycol” version) respectively. This arrangement allows for the use of one single pump in the primary circuit, which leads to a reduction in both installation and plant management costs. The valves are modulated according to the actual requirements of each user. The modulation speed of these valves is such as to provide a quick and accurate response to the users’ requirements.
This enables feeding the users with water at a temperature that is often above 7°C, which consequently leads to a direct

AQUA Link
AQUA Link An evolved hydraulic module designed to optimise the energy specifications of chilled water production and distribution systems requiring the simultaneous presence of a primary air treatment unit and internal end elements for the treatment of secondary air. The module is available in two main configurations suitable for operation: --with a percentage of Glycol between 20% and 40% in the primary circuit --without Glycol in the primary circuit (AQUA Link NG; the secondary circuit never contains Glycol) The range of power available to the various utilities (UTA and Chilled Beams) varies based on the version that is being examined, as the two configurations (with and without Glycol) are suitable for operation in different climatic conditions where the powers intended for fresh air and secondary air treatment differ greatly. For further information on this topic please refer to the data provided in the attached tables.
STRUCTURE
Indoor version structure The load bearing frame is built with polished, pickled sheet steel with textured epoxy-polyester powder coating (Colour RAL 7035). Stainless steel screws Outdoor version structure The load-bearing frame is built with galvanised sheet metal, painted with textured polyester powders RAL 7035 at 180°C, which confer high resistance to atmospheric agents. Stainless steel screws. Panelling Built from sheet metal coated with textured RAL 7035. The removable doors are fitted with handles to make them easier to take out.
HYDRONIC CIRCUIT Common standard parts include: primary circuit pump, 2-way regulation valve on the primary circuit to regulate the temperature to the secondary circuit, gate valves, expansion vessel, relief valve. The version with Glycol also includes: inertial tank, plate exchanger The NO Glycol version also includes: mixing manifold
HEAT EXCHANGER
(only for the version with Glycol) AISI 316 stainless-steel braze-welded plate evaporator, housed inside a closed-cell insulating casing. The exchanger can be single or double. Double exchangers are already supplied complete with manifold to guarantee a single hydraulic fitting.
MIXING MANIFOLD
(only for the NO Glycol version) It has an adequate diameter to ensure the water flows are mixed correctly and is supplied with a relief valve and drainage valve to promote drainage.
PRIMARY CIRCUIT ELECTRIC CIRCULATION PUMP
(Gold supply + plate exchanger or mixing manifold) One-piece impeller pump with direct motor-pump coupling using a single shaft in chrome-plated steel. Cast iron body and impeller, mechanical seal, two-pole three-phase electric motor with electric protection IP 54. Variable-operatinon pump controlled by external inverter. It is possible to choose the single or double-circulation pump version managed with rotation logic and assistance in case of failure. The pumping unit in the version with Glycol is suitable for operation with elevated glycol percentages, between (20% and 40%).
SECONDARY CIRCUIT ELECTRIC CIRCULATION PUMP (Chilled Beams supply, optional)
One-piece impeller pump with direct motor-pump coupling using a single shaft in chrome-plated steel. Cast iron body and impeller, mechanical seal, two-pole three-phase electric motor with electric protection IP 54. Variable-operating pump controlled by external inverter. It is possible to choose the single or double-circulation pump version managed with rotation logic and assistance in case of failure.
CIRCULATION PUMP ROTATION SPEED REGULATION INVERTER Each pump (or pair of pumps) is governed by a dedicated inverter controlled by customised regulating logic. The inverters are contained inside the electric control panel which is accordingly cooled by installed fans and shutters for air circulation.
TWO-WAY MODULATED VALVE INSTALLED ON THE PRIMARY CIRCUIT TO REGULATE THE TEMPERATURE OF THE SECONDARY CIRCUIT Motorised automatic regulation valve to control the flow of water to the plate exchanger or to the mixing manifold. The valve is regulated by a temperature signal sent by a probe on the water flow pipe downstream of the plate exchanger. The temperature probe is installed on the secondary branch when the unit is configured with circulation pumps on the secondary branch. Alternatively, the probe is supplied and must be installed according to the instructions provided in the user and maintenance manual.
ELECTRIC CONTROL BOARD The board includes: • main isolating switch • thermal magnetic circuit breakers for the pumps

AQUA Link • pump relays • three-phase inverter rpm regulator for each hydraulic circuit • protective thermal magnetic circuit breakers for the inverter/s • IQnomic module to manage I/O signals from the utilities • cut-off transformer • cooling fan Electrical power supply 400V/3~/50Hz.
CHECKS AND SAFETY DEVICES • temperature probe in the flow water to the Chilled Beams circuit • pressure probe to control the rate of pump operation on the primary circuit (if there are pumps on the circuit a pressure probe will also be installed on the secondary circuit). • motorised two-way infeed valve to the heat exchanger or the mixing manifold. • the standard version for outdoor installation is equipped with frost-protection heating elements for the plate exchanger, when included (version with Glycol), and for the main parts when the temperatures make it necessary.
INSPECTION The units are inspected in factory to check the hydraulic seal and correct electrical cabling of the parts.
VERSIONS and ACCESSORIES Single circulation pump for primary circuit (standardAQUA Link 1P) The design includes only one circulation pump on the primary circuit. The same pump supplies the thermal exchange coil inside the air treatment unit, as well as the plate exchanger or the mixing manifold on the Chilled Beams circuit. The circulation pump is controlled by an inverter that regulates the speed of rotation based on the real request from the utilities. There are two types of useful pump head: “standard head” and “increased head”. Double circulation pump on the primary circuit (optional – AQUA Link 2P) The design includes 2 circulation pumps on the primary circuit. The operating logic controls timed operation of the 2 pumps and the automatic intervention of the operating pump if one of the two breaks down. It is possible to choose between two types of useful pump head: “standard head” and “increased head”. Circulation pumps to the secondary circuit on the Chilled Beams circuit (optional – AQUA Link 1P-1P/2P-2P) The standard unit does not require the use of circulation pumps to supply the Chilled Beams. It is possible to select either a single or double circulation pump accessory for the secondary circuit. It is possible to choose between two types of useful pump head: “standard head” and “increased head”.

Version for indoor installation (standard – AQUA Link IN) This version does not have closing panels along its perimeter or a cover on top (supplied separately as an option). Any electrical resistance is provided to protect the components, regardless of the percentage of glycol. Version with Glycol for outdoor installation (optional – AQUA Link OD) This version is designed with closing panels around the entire perimeter and cover on top. The structural work is built with galvanised sheet steel painted with textured polyester powders in RAL 7035. The electrical control panel is designed to provide protection IP 55. Plate exchanger and circulation pumps (if included) on the Chilled Beams circuit will always be protected from low temperatures by a heating cable. The installer must be careful to protect sections of pipes that send supply water for the secondary circuit to the AQUA link unit inside the building from frost. For glycol percentages up to 30%, at a minimum outdoor temperature of -10°C, no other additional form of protection is required. With glycol percentages between 30% and 40% heating cables are added to protect the pumps, the servo-control for the 2-way valve and the electric control panel. No Glycol version NG (optional- AQUA Link NG) The No Glycol version requires both primary and secondary pumps to operate on pure water, without the addition of ethylene Glycol. This version is therefore suitable for operation in mild climatic conditions where the temperatures never subject the system to the risk of frost (for example: completely indoor installation). The last two digits of the machine’s alphanumeric identification code indicate the percentage of Glycol required for the primary circuit. In the No Glycol version, these two digits are replaced by the acronym “NG”. If this version is used for outdoor installation, a series of heating cables will need to be set up accordingly to protect: pump volutes, mixing manifolds, pipes inside the machine. WARNING: it is the installer’s responsibility to protect the sections of machine infeed and outfeed pipes that lead to the chilled beam circuit and chiller, including the inertial tank.
The double pump to the secondary circuit can only be selected if there is a double pump to the primary circuit. The possible versions, with reference to the number of pumps Swegon reserves the right to alter specifications. 20120904

OPERATING LIMITS UNITS WITH GLYCOL INDOOR VERSION Units containing Glycol in the primary circuit and made for indoor installation are built to operate at outdoor temperatures between +3°C and +45°C. They therefore do not provide the installation of heating cables to protect the internal components. For operation at temperatures outside of the aforementioned range, it is necessary to contact our Technical Office. OUTDOOR VERSION Units containing Glycol in the primary circuit and made for outdoor installation are built to operate within the following limits, whose values depend on the percentage of glycol in the primary circuit. • With a 20% concentration of ethylene glycol, the minimum admissible temperature is -5°C • With a 30% concentration of ethylene glycol, the minimum admissible temperature is -10°C • With a 40% concentration of ethylene glycol, the minimum admissible temperature is -20°C The overall maximum admissible temperature is 45°C The plate exchanger is always protected by a protective heating cable on the secondary circuit that contains water. If there are pumps installed on the secondary circuit, the volutes are always protected by a heating cable as well as preinstalled pipes. The installer must protect any connecting pipe sections between the indoor system and AQUA Link For temperatures below -15°C (i.e. for glycol percentages between 30% and 40%) a series of heating elements designed to protect the main parts (pump motors, valve bodies...) and the electrical control board must be set up For operation at temperatures outside of the aforementioned range, it is necessary to contact our Technical Office.
UNITS WITHOUT GLYCOL Units without Glycol in the primary circuit are designed and built to operate at outdoor air temperatures between +3°C and +45°C. For operation at temperatures outside of the aforementioned range, it is necessary to contact our Technical Office. For outdoor installation it will nevertheless be necessary to set up a series of heating elements against accidental low temperatures to protect: pump volutes, mixing manifolds, pipes inside the machine. WARNING: it is the installer’s responsibility to protect the sections of machine infeed and outfeed pipes that lead to the chilled beam circuit and chiller, including the inertial tank.

An iterative method was used to calculate the following values for each hour of operation of the chiller serving the plant: • The hourly COP values; • The power absorbed on an hourly basis and the absorbed energy, as a consequence. The analysis has enabled identification of: • The energy consumed by the variable setpoint system (supposing that the water temperature delivered by the chiller varies according to the chill request);
• The energy consumed by the same system, but with a fixed setpoint, producing water at a constant temperature of 7°C for the GOLD air handling unit and chilled beams regardless of fluctuations in the required power. The trends of the COP value measured every hour throughout the annual 8760 hours is illustrated below.

The chiller is built in a multi compressor version, with the possibility, therefore, of lowering the power supply based on the power request. The temperature of the chilled water being produced depends on the request from the utilities and varies continuously between the two set values. 2. The AQUA Link module, in turn, is composed of: --variable flow-rate circulation pump to supply the primary circuit --pressure probe to control pump rotation speed --decoupling and mixing manifold to supply the chilled beams
--motorised modulating two-way valve to control the manifold supply flow rate --taps, valves and hydraulic connecting pipes for the various components 3. AHU equipped with heat recovery system (enthalpy wheel) and finned-coil thermal exchanger complete with 2-way modulating regulation valve 4. chilled beams supply pump with variable operating rate and relative pressure probe 5. chilled beam system equipped with two-way water supply shut-off valve.

In terms of the previous analysis carried out on Stockholm, the overall chiller power therefore remained unchanged. Accordingly, the two analyses refer to buildings of different sizes. The distribution of powers between AHU and chilled beams changes due to the different climatic conditions in southern European areas with a high dehumifidying requirement. Through an interactive procedure for each single hour of chiller operation serving the system, the following were evaluated: --the hourly EER values --the hourly rate of power absorption and consequently the absorbed energy
The analysis determined: • the energy consumed by the system with a variable set (assuming that the water supply temperature from the chiller varies based on the request for cold). • the energy consumed by the system, at a fixed set however, that produces water at a constant temperature of 7°C for Gold and chilled beams, regardless of the change in required power. The progress of the EER value read at an hourly rate for 8760 hours per annum is provided below.

Installation tips Check that the location where the unit is installed provides for easy connection of the hydronic piping coming from the chiller and the terminal units. Refer to the dimension drawings attached to this Technical Booklet to locate the connections. Place the unit so that a minimum distance is left, as shown in the dimension drawings. Place the unit in a manner that assures the lowest environmental impact (noise emissions, integration with nearby structures, etc.).

AQUA Link
Summary Advantages for the fitter The construction of a hydronic system serving the air conditioning unit in a building is undoubtedly a complex operation both hydronically and in terms of easy management and control, first of all because the main elements making up the system (chiller, UTA, chilled beams) must be selected and, secondly, because they must be networked. Besides the main parts mentioned above, a hydronic system also comprises a series of “accessory” components such as pumps, tanks, shut-off valves, control valves, filling units, manifolds for circuit mismatching, etc. that must be selected, installed in a dedicated compartment (distribution box) and interconnected. The operating logic at the design stage may be affected by the features of these components and their capacity to respond to control signals originating from the system constituting elements. AQUA Link was designed to simplify commissioning of the plant, thus reducing both installation and plant management costs. This is why it is complete with all the elements required for the hydronic circuit, which are normally excluded from the supply of the main units and must be procured from the fitter. Provision of these elements in one single shell, that is sized by the manufacturer at earlier stages, offers a number of advantages: • One single interlocutor for the entire plant eliminates possible inconveniences relating to identification of responsibilities and difficult communications with the various parties involved; • Accurate sizing that can be tested at any time against complete documentation; • Quick commissioning compared to other solutions: the system only requires hydronic and electrical connection between the chiller, the users and AQUA Link to operate; • One individual standardised communication protocol between the various elements; • Well-organised, compact and easy-to-find location of components; • No dedicated compartment required to contain all the featured elements (when the outdoor version is selected); • Operating options to adapt AQUA Link to the different plant engineering requirements (high heads, mismatching of primary and secondary circuits, installation outdoors or indoors, etc.); • A dedicated selection software to check the performances of the unit according to the features of the served plant.
Advantages for the end user After implementation, the system must operate smoothly without downtimes and with minimised energy consumption, yet meeting the users’ requirements. High chiller and terminal unit performances are no guarantee that the second objective above be achieved, especially if, as is the case with all traditional plants, the production temperature of chilled water is established univocally at the design stage and is determined according to the heaviest work conditions envisaged for system operation. As a matter of fact, the operating conditions of the system vary according to different parameters: --indoor temperature; --outdoor temperature; --outdoor air humidity; --number of people in the room(s); --exposure of various areas to sun radiation; --possibility to go for free cooling; --etc. This said, it is fundamental that the system responds to the users’ requirements in real time. Thanks to this option, for instance, the unit heavily consumes energy only when the operating conditions are heavy. This results into a decrease in global energy consumption that derives from improved energy efficiency for the chiller and reduced energy requirements for water-glycol blend pumping. The awareness of the end user on matters regarding energy consumption is undeniable and self-evident. AQUA Link can play a major role in this thanks to: • Reduced indirect consumption: the consumption of energy supplied to the chiller and used to produce chilled water is reduced through a setpoint that varies continuously and according to the users’ requirements; • Reduced direct consumption: the consumption of energy used to pump water to the primary and secondary circuits (version 1P-1P or 2P-2P) is reduced through inverter-controlled variable pumps that only absorb the min. amount of energy required by the plant; • Reduced indirect consumption: the consumption of energy required for water pumping is reduced through the use of one single pump to the primary circuit to serve both users. • Decreasing of footprint: all equipment and components are condensed in one unique volume, AQUA Link can be placed outdoor.
