SYSTEM OVERVIEWDUCTED units offer the ultimate in flexibility of design, airdistribution and integration of ventilation. It also tends to bethe most expensive installed cost option. However cost canbe minimized by serving multiple rooms with a single unit the loss of individual room units can be countered withthoughtful control design.SYSTEM SELECTIONConsiderations:¡ Is there a ceiling void space?¡ What is the height of the void space?¡ What level of ESP is likely to be required¡ Is there a requirement to introduce ventilation intothe space via the FCU?¡ What level of control is required?DESIGN OPTIMIZATIONDucted RangeModelFXDQ07 1218 24Height7 7/8 "07 15FXMQ-P18 481113/16"0.17"0.80"20% ofunit AFR0.56"18 1/8 "CONTROLS ANDSTANDARDSApplication Examples:72 96Max.

Zoning VRV systems with DZKVRV Meets VAV - Features & BenefitsDZK - Daikin Zoning KitThe DZK solution increasest he f le x ib i l i t y o f V R Vapplications by allowingmultiple zones to be servedby one indoor unit fan coilwhile still providing individualtemperature control.Up to 6 separate dampers supply variable air flow to the zones inresponse to individual zone thermostats.Zoning BoxThe zoning box is a plenum with motorizeddampers that constantly modulate theconditioned air flow into each zone throughstandard ductwork, in response to the demandfrom the individual zone thermostat.Main ThermostatThe main thermostat is a wired color touchdisplay master unit used to configure the DZKsystem. It can also be used as the thermostatfor one or all of the zones.Zone ThermostatThe zone thermostat is a wireless, batterypowered, touch display unit that is used forone zone. Each zone thermostat monitors andallows the user to select a comfortable roomtemperature, and program or adjust the controlfunctions for the room.DZK BACnet Gateway ModuleThe DZK BACnet Gateway module allowsindividual room control via any BACnet/IPcompatible Building Management System.24

Heat Pump or Heat Recovery?The Various Heat/Cool Changeover OptionsHeat Pump¡ The 2 pipe Heat Pump system is the equivalent of a 2-pipe chilledwater system¡ A heat pump system provides the means of heating OR cooling atany given time¡ Multiple heat pump systems can be zoned and will work independentlyof each other¡ When demand is met by an indoor unit the unit will work on fan only or thefan will cycle on/off until demand returns or mode change occursCoolingCoolingHeatingHeatingHeat Recovery¡ The 3 pipe Heat Recovery system is the equivalent of a 4-pipe chilledwater system¡ A heat recovery system has the ability to provide simultaneous heatingAND cooling¡ When both heating and cooling occur simultaneously, system and buildingenergy can be better utilized¡ When demand is met by an indoor unit the unit will work on fan onlyor the fan will cycle on/off until demand returnsCooling26CoolingHeatingHeating

SYSTEM OVERVIEWShould I Use Heat Pump or Heat Recovery?There are three main factors that dictate whether a HP or HRsystem should be selected. All these factors should be consideredin each case to determine an appropriate selection:SYSTEM SELECTIONClimate Zones of North AmericaSubarctic / ArcticSPECIFICATIONS& ACCESSORIESDESIGN OPTIMIZATIONVery CONTROLS ANDSTANDARDSGEOGRAPHYThe location or the project will often dictate what type ofsystem will be required. Projects in temperate climates tend touse Heat Recovery due to the changeable load demands thatcan occur through the course of a day. However areas withdefined seasons or little demand for simultaneous heating orcooling throughout the year will usually utilize Heat Pump.27

Heat Pump or Heat Recovery? (cont.)BUILDING LAYOUTSites with open plan areas and/or similar orientation will oftenbe satisfied by a heat pump system, irrespective of geography.On the other hand, if the site has many aspects, individualrooms and/or heat loads, this may define the client requirementtoward heat recovery. Differing internal room load demandsmay see the need for cooling for longer periods of the year.OCCUPANCYThe type of end user will often trump any other consideration.Typically a multi-tenanted site will require a heat recovery systemas the ability for individual mode control is paramount. Typicalexamples of this include hotels, assisted living, condos as wellas offices. It is always important to establish from the outset if anoffice application is to have multiple ngHEATRECOVERYUltimately there are many applications where the answer will beboth Heat Pump AND Heat Recovery28

SYSTEM OVERVIEWAir Cooled or Water Cooled?Factors that Benefit the use of VRV-IV W-SeriesAir to air VRV systems make up the majority of VRVinstallations This is due to the following:¡ Ease of installation (no water system required)¡ Less initial capital costsSYSTEM SELECTIONHowever Water Cooled VRV can have certainadvantages:¡ Greater energy efficiencies¡ Localized CU installation(reduced pipe runs)These advantages come in to playwhen the following are present:SPECIFICATIONS& ACCESSORIESDESIGN OPTIMIZATION¡ An existing chilled water loop¡ Extreme ambient conditions¡ An ability & desire to utilize alocal geothermal sourceInternal PlateHeat ExchangerWater Cooled VRV - Existing Water LoopCONTROLS ANDSTANDARDSBy utilizing anexisting water loopin the building, theadvantages of greaterenergy efficiency canbe promoted withouthaving to offset capitalcosts. In additionVRV-IV W-Series CUsare usually locatedlocally to the area theyare serving and willBoiler Tower Water Looptypically attach to thewater loop already running through the building. This negatesthe need to run copper piping through risers to a remoteplant space (be aware that VRV-IV W-Series CUs are internalmounting units).29

Air Cooled or Water Cooled? (cont.)Water Cooled VRV - GeothermalClosed Loop Buried in GroundA ground-source VRVheat pump system combinesthe advantages of bothtechnologies into onesystem, making it oneof the most efficient HVACsystems available andachieving savings overeither GSHP or VRF on theirown. The constant ambientconditions below groundalso ensure that these savingsare realized year round.There are two main typesof systems: closed loopand open loop. Closed loopsbury water pipes eitherin solid ground or in a watersource (like a pond or lake).An open loop draws fromgroundwater, like a well, andreturns it back to source.Closed Loop in Surface WaterOpen Loop using Ground Water30

SYSTEM OVERVIEWDesign Criteria:Water loop design is the responsibility of the engineer.However, two facts are needed from Daikin:The minimum & maximum entering water temperatures:50 F-113 F for Cooling27 F-113 F for Cooling on a Geothermal System50 F-113 F for Heating14 F-95 F for Heating on a Geothermal SystemSYSTEM SELECTION¡¡¡¡A suitable water flow rate:¡ 13.2gpm to 39gpm per module Boiler & Tower SystemSPECIFICATIONS& ACCESSORIESDESIGN OPTIMIZATION¡ 21gpm to 39gpm per module on a Geothermal System).* (Be aware that conditions need to be met when EWT for heatingis required below 50 F – seek assistance for these applications)Other consideration:¡ When VRV is to be applied with an open loop system, a 3rd partyCONTROLS ANDSTANDARDSheat exchanger is required to ensure the plate heat exchanger ofthe VRV condensing unit operates in a closed loop system.¡ The VRV condensing units have a heat output of approx. 2400btu’s.Where multiple units are placed in an enclosed area, any potentialheat build up must be addressed (either with adequate ventilationor even a fan coil unit).¡ From the CU pipe connection to the fan coils, the equipment,controls & selection process is identical to air cooled VRV.31
