V RF systemOur answer to VRFMitsubishi Electric sets the boundaries of VRF technology with the City Multi range, which is available usingR410A refrigerant with zero ODP (Ozone Depletion Potential). The range has been specifically designed fortoday’s building requirements and addresses key market issues such as energy efficiency, adaptability andreliability. With user friendly control systems utilizing Internet technology and integrated cooling and ventilationindoor units, City Multi is the benchmark and market leader in VRF technology.VRF is a multi and direct expansion type air conditioning system that one outdoor unit can be connected withmultiples of indoor units. The amount of refrigerant can be changed freely according to the load in the indoor unitbecause inverter compressor is used in the outdoor unit. Zoning in a small office is possible with a small capacityindoor unit. Energy conservation is easily handled because individual indoor unit can stop and start its operationas needed. Indoor unit has a lot of models in order to suit various interior design needs. Appliance to controlseparating heat of cooling in evaporation from heat in condensation is becoming important in air conditioning in thebuilding.Sophisticatedyet simple technologyInverter driven compressorReliableOutdoor unitJointHeaderDesigned and manufactured to the highest standards, theCity Multi range offers one of the most reliable airconditioning systems available.

I nverter Driven CompressorTechnology - now up to 50HPLowStartingCurrentsUsing inverter driven technologysaves energy for several reasons:Unbeatable EfficiencyHeat Interchange CircuitThe unique Heat Interchange Circuit (HIC) enhances efficiency by providing additional sub-cooling and allows theexpansion device to control more effectively the refrigerant distribution, thereby increasing the operating efficiencyand reducing the volume of refrigerant in each system.City Multi Refrigerant CircuitCompressorCondenserAccumulatorHeat exchangerHigh temperatureBypassSupercooledheat exchangerLow temperatureElectric expansion valveMedium temperatureCommon Refrigerant CircuitCompressorCondenserAccumulatorExpansionvalveThe compressor varies its speed to match the indoor cooling or heating demand and therefore only consumes theenergy that is required.When an inverter driven system is operating at partial load, the energyefficiency of the system is significantly higher than that of astandard fixed speed, non inverter system.The fixed speed system can only operate at 100%, andpartial load conditions prevail for the majority of the time.Therefore fixed speed systems cannot match the annualefficiencies of inverter driven systems.100%Using proven single inverter driven compressortechnology, the City Multi range is favoured by theindustry for low starting currents (only 15 amps for a16HP YHM-A outdoor unit), a smooth transition acrossthe range of compressor frequencies and foreliminating systems.15%Heating / Cooling CapacityLinear CapacityControl15Hz>All the City Multi compressors are inverter-driven type (4~50HP).Compressor FrequencyCooling:97HzHeating:102Hz* imageEvaporatorElectric expansionvalveEvaporatorPage 5 Page 6

I ntelligent Power Module (IPM)TechnologyThe YHM-A range from Mitsubishi Electric provides precise control of energy input, through utilization of IntelligentPower Module (IPM) technology. Employing this technology it is possible to closely match the buildingrequirements, achieving more accurate control of the occupied space. By using incremental 1Hz steps of capacitycontrol, the amount of power input required is significantly reduced, resulting in greatly improved COP’s.In addition, IPM technology ensures effective performance under partial load conditions, a condition that mostsystems will be in for the majority of the normal working life cycle. By taking account the efficiency at both partload, and peak load conditions, R410A City Multi is designed to provide unbeatable year round/seasonal efficiency.Total Energy ConservationComparison of COP (energy efficiency) – 8HP systemThe difference between YHM-A and previousMitsubishi Electric modelsTechnology is key when increased efficiency is demanded.The City Multi YHM-A range is able to deliver this in simple ways.A highly efficient R410A scroll compressor design results in less friction losses at the motor. A simplified refrigerantcircuit (low pressure loss) including new accumulator design also adds a few more points to the efficiency scale.Enhancements to the heat interchange circuit, an inverter driven fan motor and a heat exchanger design again addvital increases to overall system efficiency and COP’s.COP5.04.5The importance of COP4.03.53.02.52.02.8729%Energy Saving4.0234%EnergySaving4.33High COP (Coefficient of Performance)is realizedCOP stands for “Co-efficient of performance”. It is a measure of the useful energy a system can deliver comparedto the energy it consumes. It is calculated by dividing the energy output by the energy input of a system. Thehigher the figure then the more efficient the system is deemed to be, with commensurate reduced running costs.Mitsubishi Electric VRF models, the world's highest energy-efficient ACs, will undoubtedly reduce millions of tonsof CO2 emissions.0R22Our equivalent product10 years before PUHY-200YMFStandard modelHigh COP model* Average COP of cooling / heatingPage 7 Page 8

E fficient R410A refrigerantHistory of refrigerantR22, an HCFC-based refrigerant, has been a popular choice for most chillers. R22 has been targeted by theMontreal Protocol to be phased out in new equipment. Additionally, the European Union and other countriesgovernments are enforcing a ban of HCFC-based refrigerants for new installations.Because of these restrictions, R410A refrigerants is increasingly available. R410A is a blend of HFCs, which do notdeplete the ozone but may contribute to global warming.Technical aspects of refrigerantFor the EnvironmentR410A is a more efficient refrigerant as it has a higher specific heat capacity when compared to R407C or R22.This higher energy carrying capacity allows for smaller pipe sizes, longer pipe runs and reduces the volume ofrefrigerant within a system. This is a major factor when complying with ISO5149, an International Organization forStandardization concerning, "safety of persons and property for the design, construction, installation and operationof refrigerating systems".Reduction of operation noiseEnhancing environmental care(measures for the RoHS Directive and the refrigerant reduction)Every unit is in compliance with the RoHS Directive,* which stands for the restriction of hazardous substances:Lead-free soldering is used to avoid Lead Groundwater Contamination on the print board. The amount ofrefrigerant on the unit has also been reduced to enhance environmental care.* RoHS Directive: the restriction of the use of certain hazardous substances in electrical and electronic equipment that has been sold in EU since July 2006Improvement of COPImprovement of COPImprovement of reliability and easy maintenancePage 9 Page 10

The importance of controlRemote ControllerIndividual Remote ControllerCentralized Remote ControllerThe need for control is paramount in orderto optimise the performance of anyair conditioning system and minimizeits running costs. Mitsubishi Electric offersa wide range of control options designedto meet such needs.Operating an air conditioning system withoutthe right control can prove costly. It's thereforeimportant to ensure that every system is correctlyspecified to the degree of control it requires.Mitsubishi Electric have a wide range ofcontrols available 'off-the-shelf' and individualcontrol systems can be specifically designed tomatch.Good controls will benefit any application,large or small. Air conditioning products needto react to a variety of factors: different room sizes,usage and staff levels; changes in the climate;electronic equipment and lighting ...thelist goes on. So whatever the application, optimumcontrol of air conditioning systems is essentialand will result in a constant, comfortableenvironment, which in turn is both energyand cost efficient.A degree of differenceWhen an air conditioning system is not properlycontrolled, it will not run as efficiently as itshould. For every degree that the system deviatesfrom the required temperature, energycosts can rise by up to 5%. Specify one of themany control options from Mitsubishi Electricto ensure air conditioning works as intended,whilst giving the optimum amount of control.The simpler, the betterWith the array of comprehensive control systemsavailable from Mitsubishi Electric, it becomessimple to design and install air conditioningsystems. From a simple hand-heldcontroller to a G50 system - you are in control.Remote ControllerPage 17 Page 18
