Features Water system energy-saving control A5MWC-BR series units possess a unique algorithm that control the chilled water pump, cooling water pump and cooling tower. It can switch on or off the cooling tower based on the temperature of the cooling water. Once all compressor is unloaded, cooling water pump will be shutdown. Thus, effectively lowering the energy consumption of the system during transitions season or low load operation. The unit also has a two-way valve interlocking function. In the event where all fan coil is not in operation, the unit will shut down the pumps and cooling tower prior of entering standby status.
Low carbon and environment friendly The unit is capable of providing cooling and heating through different system design. Energy recovery model is available for a better efficiency and energy saving application. R410A refrigerant is also used, further enhancing its environment sustainability due to the zero ozone depletion potential of R410A refrigerant. .
Dual backup operation increase reliability There are 3 or 4 sets of compressor in every single unit, failure of single compressor will not affect the operation of the unit. Whereas failure of a unit in a combination application will not jeopardize the entire system. A5MWC-BR series does not need another master unit as standby for multiple units application. This dual backup system greatly enhance its durability and reliability.
evaporator Shell and tube heat exchanger with large pipe diameter is used for evaporator and condenser, which has higher tolerance on water quality. While the unit has stronger fouling resistant, inner groove copper tube are used inside the shell and tube heat exchanger. This increase the effective heat transfer surface, inducing turbulent flow to delay fouling formation and increasing thermal efficiency at the same time. A sets of electronic expansion valve is used for precision throttling. This dynamic throttling is vital when the water temperature condition changes, the unit still able to maintain it target superheat. Thus, increasing reliability and efficiency of the unit.
Service life balancing A5MWC-BR series have build in compressor service life balancing. Where compressor with the least operation time will be started first. This feature is carried across units in multiple units application.
Self-protection and diagnosis function The unit come with self diagnosis and protection feature, utilizing arrays of build in sensors and switches. When system falls into abnormality, error code will be display on the acousto-optic or wired controller.
A5MWC-BR series have smaller carbon foot print compare to its air cooled counterpart. Making it easier to be transport around without the needs of hoist or crane. This is important especially for replacement project.

Robust Casing The casing is coated and made from galvanized steel, making it very robust in normal weather condition. By enclosing the whole unit, noise level of 56 dB(A) can be achieve, which is well below hazard level.
Zoning Capabilities Units in different areas and floors can be control separately, such is the advantages of using chilled water system compare to conventional centralize direct expansion system.
Simultaneous Operation & Wide Operating Temperature Using the heat recovery models, a system that required cooling and heating operation can be achieve. Besides utilizing the waste heat energy generated from air conditioning, the unit have a wider operating temperature range.
Wide Selection of Units Acson A5MWC-BR series consist of 20 ~ 40 tonnage cooling/heating capacity. Having a wide selection of units enable flexibility in design. One can opt for lower carbon foot print by using larger unit or multiple smaller units for better part loading capabilities.
Modular Capabilities A5MWC-BR series can be setup up to 16 units for a single system. Making it very ideal for future expansion project.
Heat Recovery (Optional)
. A5MWC030BR can be fitted with a heater so that it can provide heating and hot water simultaneously.
Free Hot Water For the heat recovery model, the temperature of the condenser can reach up to 55˚C. Since air conditioning is almost a must in our climate, we are literally providing hot water for free.

Water system installation schematic diagram Connecting water pipes ■ Water pump is field supply. Sizing of the water pump is important to overcome resistance of the water pipes ■ Water pressure gauges and thermocouples/thermistor must be installed at the water inlets and outlets to facilitate the reading of unit operation status. ■ The heat exchanger at the water side is made of stainless steel. Water scale may accumulate depends on the water quality and must be cleaned using chemicals from time to time. Therefore, a chemical cleaning pipe connector needs ■ Ensure the flow rate is in the range. Low flow rate will reduce performance of the unit due to scale formation, triggering anti-freeze sensor, and/or refrigerant leakages which caused by corrosion. While flow rate that is too high will cause erosion corrosion. ■ A adiabatic water tank with a proper volume is recommended to be installed. If the capacity is too small, the unit might frequently restart, which causes wear and tear on the compressor. ■ An expansion tank is recommended to be install at the return of the chilled water system. Water inside the chilled water system will experience volume changes due to temperature changes. ■ An auto relief valve must be installed at the highest point in the water system. A suitable water discharge valve must be installed at the lowest point in the water system. ■ The water pipes must be adiabatic to avoid heat loss and condensate water. ■ Please follow the "Illustration for water system installation" and drawings from the certified personnel while installing the water system. ■ Install the strainer on the inlet pipe and rinse the filter screen after commissioning. ■ Before supplying water, make sure that no sand, rubble, rust, soldering tin residue or other impurities exist in the pipe, as these things might damage the heat exchanger. ■ While rinsing the water system, please bypass the unit and the terminal heat exchanger using by-pass valves. 23

Install one electric two-way valve in each piece of terminal equipment to implement the interworking between the valve and the terminal. (Generally, relevant interface is preserved on the terminal fan coil unit. For details about wiring, please refer to the instruction to fan coil unit.) 4. At least one variable-frequency water pump is required to serve as the chilled water pump for the water system (it is recommended to use variable-frequency water pumps only to simplify the control pressure. Adopt variable-speed water pump and install transducer to implement variable frequency. 5. Install the differential pressure sensor ∆P between the main pipes for chilled water supply and return. The location is shown in the schematic diagram of the water system. Check the difference between the chilled water supply pressure and return pressure, and transmit the signal of pressure difference change to the variable-frequency water pump, so as to change the speed of the variable frequency water pump and 5.1
5.2 Requirement for flow rate changes: the rate of which the flow rate is changed cannot be too frequent. Otherwise, the stability of outlet temperature and terminal regulating valve will be affected. It i recommended to fix the flow rate changes to 2% ~ 30% per minute, the specific value varies depends on the model, control, and cycle time of water in the system. The optimum rate for flow rate changes shall be determined on site after debugging, and the adjustment rate of 10% per minute could be use as the initial value for system debugging. 6. In the wiring diagram that are shown previously, components such as contactors and terminal block can be seen. It was meant for constant flow rate system, a variable flow rate system will require frequency converter, DDC, differential pressure sensors and other components that might be needed in a variable flow rate system.

The water system with separate pumps for each unit is applicable only to the scenario where a few units are used (that is, one or two units). When the quantity of units is large, it is not recommended to use this type of water system. Because: 1. Separate pumps for each unit are not cost-effective when there are many units; 2. The water flow rate in the system might be too low, which can affect the unit performance. For example, for a group of 10 units with 200 terminals connected. In the case of low load, if only one unit and all terminals are running. The water flow rate in the system will be too low and performance of the system will be affected. Application instruction: 2. Install electric two-way valve on the terminal side to implement the interworking between the electric two-way valve and the terminal.

3. For chilled water system on the unit user side, install an independent water pump for each unit and configure interworking between the water pump and the unit. Install electric two-way valve on each slave unit to implement the interworking between the electronic two-way valve and the unit. 4. For the hot water system on the unit heat source side, install an independent water pump for each unit, and configure interworking between the water pump, cooling tower and the unit. Install electric two-way valve on each slave unit to implement the interworking between the electronic two-way valve and the unit. Interfaces implementing the preceding functions are preserved on the master unit. For details about wiring, please refer to "Control System Instruction - PCB instruction". Note: 1.
When cleaning the water system, close all the gate valves as shown in position 1 2 or 3 4 . Open the 5 or 6 valve to bypass the units to avoid foreign matters in water system entering the plate of units, which may

Hydraulic calculation and pipe system Pipe design for the air-conditioning system ■ Please ensure the piping for both condenser and chilled water system is sufficient. For example, the water system that the unit works properly. ■ Deploy pipes properly, use pipes with reverse return if possible. Although the initial investment is increased, the flow rate will be more stable. If pipes have no reverse return design, pressure between branch pipes must be balanced in the design process. ■ When determining the diameters of pipes, ensure it is suitable for that flow rate as such the resistance, noise and performance of the unit is optimum.A larger water pipe will require higher initial investment but lower flow resistance and smaller pump could be use, lowering operating cost. It is crucial to find a pipe diameter that balance between investment and operation cost. Avoid a large water flow with small temperature variation to ensure that the pipe system . is economical. ■ In the design process, calculate water resistance accurately to ensure that water pressures between circuits are well balanced and that the air conditioning system works with the best water and thermal conditions. ■ The pipe system of an air conditioning system must meet the adjustment requirements for partial workload. ■ The pipe system of an air conditioning system should use energy saving technologies whenever possible. ■ Pipes and accessories of the pipe system must meet the related requirements. ■ The design of the pipe system must facilitate maintenance, operation, and adjustment. * Determining the diameter of pipes in the air conditioning system The pipe diameter is determined based on the following:
d =
4 mw 3.14v
3 mw /s v = water speed m/s
The water speed should be determined by the recommendations in Table 1: Recommended water speed (m/s) Diameter (mm)

Note: 1. The total water volume of the entire hydraulic system includes the water in main pipe, water tank and terminal equipments, in which the 2-way valve is open. 2. If the water volume (V) while the unit is running is less than Vmin, it's recommended to install a water tank of (Vmin-V)L, or it will cause the unit frequent ON/OFF. 3. The Vmin in the table is calculated based on nominal cooling water flow rate and 5ºC anti-freeze. If the the water flow rate and anti-freeze temperature change, relative V min will change. 4. Above table is valid for nominal operating condition and not meant for application with addition of glycol.
Example: Calculating system water volume. A project require one unit of A5MWC030BR-FAAE,, the desired water return temperature is 12°C, main water pipe size is 2-1/2”(DN65), total length of main water inlet/outlet pipes is 50 m, 10 units of fan coils are normally open, and internal volumes for each fan coils . are 1.5 L. Volume of terminal fan coils =10*1.5=15 L. According to the table above, Vmin.=296 L. To avoid frequent unit startup/shutdown and alarms, the volume of the water tank should be no less than Vmin.-V=296-166-15=115 L.

Calculating volume of expansion water tank An expansion water tank with a proper volume must be installed to adapt to water volume changes as the temperature change. Thus, an expansion tank must be installed at the inlet of the chilled water pump to avoid freezing burst and/or pressure instability. The expansion water tank can also be used to supplement water and discharge air. Formula for calculating the volume of expansion water tank.
V P =α × ∆t × Vs Vp: effective volume of the expansion water tank (volume of water between the signal pipe and the 3
α: t: max. water temperature variation °C. Vs: water volume in the system (total water volume in the system and pipes) m3
Selection principles for water pump
Closed water circulation system: Water circulation pump lift ≥ (Pipe resistance of the water system + Partial resistance of the water system + Water pressure drop of the unit) × 1.1 Open water circulation system: Water circulation pump lift ≥(Static resistance of the water system + Pipe resistance of the water system + Partial resistance of the water system + Water pressure drop of the unit) × 1.1 In the case that multiple units share the same pump, the pump lift is calculated according to the circuit that has the maximum resistance (usually the unit that is farthest away from the pump). Note: The water flow rate of the unit should calculate according the water flow range.

Water processing method To ensure effective operation and durability. Cleaning, washing and chemical processing are very important for water systems. Different types of water circuits need to be cleaned in different ways. ■ Close re-circulation system. Water systems of this type generally require no adjustment to subdue scale and require no chemical to suppress mud and alga. This type of water system is recommended. Closed recycle systems may need anti-corrosion measures, including the following (for reference only): NaNO2, borate and inhibitors for organic materials. a. NaNO2, borate and silicate. b. High density chromate solution and pH control. d. Polyphosphate salt and silicate. Because it is hard to control water quality for closed recycle systems, we recommend that the total density of copper pipe inhibitors such as NaNO2, borax, silicate and benzothiazole should be no less than 1400 ppm. The inhibitor NaNO2 is soluble in glycol, and can be used in northern areas or in the subsystem of solar power systems. ■ Open re-circulation system. This type of water system is generally not recommended. They are exposed to the atmosphere, and are susceptible to scale, corrosion, mud and alga. Therefore, they might degrade the performance and reduce the service life of the unit. ■ Once-through system. Generally, once-through systems are only used for cooling only air conditioners. Water systems of this type use water from taps, lakes, rivers, and wells. Although the once-through system exchanges heat with the closed water circuit, it is not considered as an integral part of the water source heat pump system. Once-through systems may be troubled by either scale or corrosion. This type of water system requires large amount of and necessary anti-corrosion materials. Caution: Using water from lakelake or river willwill cause Caution: Using water form or river cause water problem of hydrulicsystem! water problem of hydrulic system! Comparison among closed recycle systems, open recycle systems and once-through systems

■ Cleaning of the shell and tube heat exchanger. 1. Clean the shell and tube heat exchanger based on the condition of site. Clean the shell and tube heat exchanger by removing the cover for water pipes opposite side. Then use a brush to clean the tubes. 2. For open recycle system, please clean the cooling tower periodically. 3. High operating pressure might caused by the following items beside heat exchanger being dirty or scale formation: Charging too much refrigerant. Air in the system. Water regulation valve setting problem or breakdown. EWT of shell and tube heat exchanger too high. 35
