FeaturesWater system energy-saving controlControl system of UWL-B5 series units can intelligently output the control signals of air conditioning chilledwater pump, cooling water pump and cooling tower, and can control start and stop of the cooling tower basedon the temperature of the cooling water. After compressors of all units deloading, the unit will automaticallyshut down the cooling water pump, and can effectively decrease energy consumption of the system duringtransitions season or running at low load. The unit has two-way valve interlocking function, when all fan coilsare shut down, the unit will shut down the pumps and cooling tower and then enter standby status.Low carbon and environment friendlyCooling and heating function can be realized through different system design schemes with reusable energyas the heat exchange system, the unit can be more efficient and energy-saving. R410A environmentalfriendly refrigerant is adopted without limit on use term, which does not destroy the ozone layer.Double backup operation makes double improvement of reliabilityThere are 3 or 4 sets of compressors in every single unit; failure of a single compressor does not affectoperation of theunit; failure of unit module does not affect operation of the combination system. During usethrough combination it doesn't need another one master unit for standby, so that the air conditioning systemis safer and more economic in investment. Double backup operation can make double increase in reliabilityof the air conditioning system; the air conditioning system may continue to run before maintenance personnelarrive, which can make maintenance and repair easy in remote areas.High efficiency shell and tube heat exchanger for condenser and evaporatorShell and tube heat exchanger with large pipe diameter is adopted for evaporator and condenser, which hashigh tolerance on water quality, while the unit has strong ability to resist filth blockage. Internal thread finnedcopper tubes are adopted inside the shell and tube heat exchanger, which can increase the effective heattransfer surface; turbulent flow type water flow process design can delay internal scale and increase thermalefficiency. Using multiple sets of electronic expansion valve for precision throttling can make precise dynamicthrottling when water temperature condition changes,and it can stably control target superheat of the unit, soas to keep safe and efficient operation of the unit.Double balance operation extends service life of the overall unitCompressors in single unit have balance operation time function; and the operation time among modules canbe balanced during multiple module combination; double balance operation design can reduce the rate offailure, which can extend the service life of the overall unit.Self-protection and self-diagnosis functionThe unit has water over-temperature protection, low water flow protection, protection for compressor frequentstart-stop, refrigerant high/low pressure protection, etc.; when the water temperature is too low in winter, theunit enter anti-freezing operation protection automatic by starting up water pump. When failure occurs, selfdiagnosis function can rapidly and accurately show the cause of the problem; acousto-optic code display canassist rapid troubleshooting.Compact and flexible air conditioning solutionThe compact modular body can be moved via good elevator without large hoisting equipment, so that it canbe easily moved into the existing water cooling machine room, and can enter the basement for replacementof old machine without dismantling the existing construction during reform of some old projects.3
Rain proof body avoids investment in machine roomsThe rain proof shell can meet the requirement of outdoor installation, which can make investment in machinerooms unnecessary. The closed body can effectively reduce the operation noise of the unit, and the minimumnoise is only 56dB(A) without noise hazard.Easily realize partitioned managementCooling capacity is under flexible collocation, units in different areas and different floors can be control start/stop seperately, people can use air conditioning in rental office when they work overtime.Multiple cold and heat sourcesHeat pump application can be realized through switch of external water lines; the system has higherefficiency with utilization of waste heat and renewable energy, which realize energy saving and low carbonoperation. The entering water temperature has wide range, which can adopt different cold and heat sources.Large capacity unit reduces installationDAIKIN new modular water cooled chiller (heat pump) unit increases 40RT large capacity single module; thenumber of unit can be reduced with large refrigeration capacity requirment; there is little installation, whichcan greatly save the occupation area; it can realize the amount of 16 modular combination in the industry,and there will be no waste for cooling capacity selection.Convenient for capacity increase of the systemWith increase of vistors flow rate and climate warming, the cold capacity of the existing central air-conditioningof the building is not enough, UWL can be moved easily and the capacity increase of the cold capacity isflexible, which has outstanding performance for the small scale capacity increase in the existing system.Trinity function (optional)UWL030B5 unit can choose heat recovery function with hot water generator built in; the unit has the trinityfunction, which can realize heating and hot water simultaneously.Primary pump variable flow designAfter all compressors of the single modular of combination system are unloaded, the unit can output controlsignal, and the water flow of the corresponding unit will be shut down; the requirement of the total water flow ofthe system is reduced; automatic adjustment is made through the frequency conversion pump, so as to easilyrealize primary pump variable flow, which can make the air conditioning system with 15% energy saving.Higher efficiency of combining operationIn the area where it is hot in summer while cold in water, the cooling is long in summer while requirement forheating is few in winter. UWL can be combined with air cooled heat pump; UWL water cooled modular heatpump has high efficiency for cooling in summer, and the air cooled heat pump is mainly for heating. This airconditioning system has high efficiency with economic investment.Living hot water is made throughout the yearThe highest hot water temprature of the condensor of UWL standard unit can reach 55 ºC, which can be usedto make domestic hot water throughout the year. Cooperated with the centralized machine, heat recovery orcool recovery of the water system can be realized; domestic hot water can be made in transistion season;the system is more stable and more efficient.4

While designing the groundwork, you must fullyconsider the strength of the floor, water discharge (the unitdischarges water while working), pipeline and wiring. If thefloor is not strong enough, the unit might fall off and breakdown,even incur bodily injuries.Screw down the chilled water unit using anchor bolts so that it willnot fall off in case of strong wind or earthquakes. To avoid damagescaused by strong wind or earthquakes, The unit must be securelyinstalled at a proper place to avoid direct hit of strong winds.Rubber cushionsQty4Size280X180X20Depending on mounting conditions, operation vibration might passthrough the groundwork and generate noises in the floor and walls.Therefore, proper vibration dampening mechanisms (such asbumper cushion, bumper frame etc.) should be in place.Corners and edges should be properly installed. Otherwise, the unitmight get unbalanced and cause the grounding pins to bend. Theunit might fall off and cause bodily injuries if it is not properly installed.19
Hoisting chillerPlease hoist the unit according to the following illustrations. Tie the cables to the four corners of the unit whilemoving it. If you tie the cables to only three corners of the unit, the unit might get unbalanced and fall off.PROTECTIVE CUSHIONHOISTING CABLE (TWO)Note: Chilled water units must be moved with great care. Accessory strips cannot be used to hoist or move the unit as they might break and cause unexpectedaccidents. Dispose all plastic bags properly and keep them away from children.20
Water system installationWater quality requirementsWater in the water system must be softened to prevent scale in the heat exchanger and affecting the heat exchangerperformance. Water not softened can also cause scale in the water pipes and cause the water resistance to increase.This affects the water flow and the performance of the water pump. Softened water must meet the followingrequirements.ItemBenchmark valuepH (25 C)TendenciesCorrosionScaling7.5 - 9.0 Conductivity (25 C)ClμS/cmmg (Cl-)/L 800 200 SO42-mg (SO42-)/L 200 Acid consumptionmg (CaCO3)/L 100 Total hardnessmg (CaCO3)/L 200 Femg (Fe)/L 1.0 0 Benchmark items(pH 4.8)2-Reference itemsS2-mg (S )/L mg (NH )/L 1.0SiO2mg (SiO2)/L 50NH Note: represents factors that may cause corrosion or scaling.Water System Installation Schematic DiagramConnecting Water Pipes No water pump is provided as an accessory. A proper water pump must be installed to overcome resistance of thewater pipes. Water pressure gauges and thermometers must be installed at the water inlets and outlets to facilitate the reading ofunit operation status. The heat exchanger at the water side is made of stainless steel. Water scale may accumulate depending on the waterquality and must be cleared using chemicals from time to time. Therefore, a chemical cleaning pipe connector needsto be installed at the water pipes (see the following figure). The water flow must be in the rated range. If the water flow is too small, scale may accumulate and degrade theperformance of the unit, cause the antifreeze device to activate, or cause rust points and refrigerant leakage. If thewater flow is too large, the unit may be corroded due to water impact. A adiabatic water tank with a proper volume is suggested to installed. If the capacity is too small, the unit mightfrequently restart, which causes wear and tear on the compressor. An expansion water tank must be installed at the return water side of the water system to adapt to water pressurevariations in the water supply system caused by ambient temperature changes. An auto relief valve must be installed at the highest point in the water system. A suitable water discharge valve mustbe installed at the lowest point in the water system. The water pipes must be a
