Installation and operation manual3 RYYQ+RYMQ+RXYQ8~20T7Y1BVRV IV System Air Conditioner4P329765-1 – 2012.09These units have (in single use) heating capacities ranging from 25 to63 kW and cooling capacities rating from 22.4 to 56 kW. In multicombination the heating capacity can go up till 168 kW and in coolingtill 150 kW.The outdoor unit is designed to work in heating mode at ambienttemperatures from –20°C to 21°C and in cooling mode at ambienttemperatures from –5°C to 43°C.1 VRV IV Heat pump outdoor unit2 Refrigerant piping3 VRV direct expansion (DX) indoor unit4 VRV LT Hydrobox (HXY(080/125))5 BP box (required to connect Residential Air (RA) or Sky Air(SA) direct expansion (DX) indoor units)6 Residential Air (RA) direct expansion (DX) indoor units)7 User interface (dedicated depending on indoor unit type)8 User interface (wireless, dedicated depending on indoorunit type)9 Cool/Heat changeover remote control switch3.2. Combination and optionsThe VRV IV heat pump system can be combined with several typesof indoor units and is intended for R410A use only.For an overview which units are available you can consult the productcatalogue for VRV IV.An overview is given indicating the allowed combinations of indoorunits and outdoor units. Not all combinations are allowed. They aresubject to rules (combination between outdoor-indoor, single outdoorunit use, multiple outdoor unit use, combinations between indoorunits, etc.) mentioned in the technical engineering data.3.2.1. Indoor unit combinationsIn general following type of indoor units can be connected to aVRV IV heat pump system. The list is non-exhaustive and isdepending on both outdoor unit model and indoor unit modelcombinations. VRV direct expansion (DX) indoor units (air to air applications). SA/RA (Sky Air/Residential Air) direct expansion (DX) indoorunits (air to air applications). Further referred to as RA DX indoorunits. Hydrobox (air to water applications): HXY080/125* series only. AHU (air to air applications): EKEXV-kit+EKEQ-box arerequired, depending on application. Aircurtain (air to air applications): CYQ*/CAV* (Biddle) series,depending on application.3.2.2. Outdoor unit combinations Single unit (stand alone outdoor unit) can be chosen from tworanges. The RYYQ* model (continuous heating) or RXYQ*model (non-continuous heating). The RYYQ* models providecontinuous comfort during defrost operation. Multi unit (multiple outdoor unit) combinations "non-continuousheating" consist of RXYQ8~20 modules. E.g.,RXYQ36*=RXYQ16*+RXYQ20*. Multi unit (multiple outdoor unit) combinations "continuousheating" consist of RYMQ8~20 modules. E.g.,RYYQ36*=RYMQ16*+RYMQ20*. Multi modules RYMQ* cannotbe used as single unit (stand alone outdoor unit):RYMQ8~20HP. Multi unit combinations can never contain RYYQ8~20 models asone of the multi modules. Multi "continuous heating" RYYQ* combinations can nevercontain RXYQ* models. Multi "non-continuous heating" RXYQ* combinations can nevercontain RYMQ* models.Standard combinations for VRV IV heat pump system are asindicated in table below, where RYYQ22~54 consists of severalRYMQ8~20 modules in the horsepower class as indicated and whereRXYQ22~54 consists of several RXYQ8~20 modules in thehorsepower class as indicated.To install the outdoor unit, the following optional parts are alsorequired.1 Refrigerant branching kit.For the selection of the optimal branching kit, please refer to"9.4. Selection of refrigerant branch kits" on page 13.NOTICEDesign of the system must not be done at temperaturesbelow –15°C.INFORMATIONNot all combinations of indoor units are allowed, forguidance, see "3.2. Combination and options" on page 3.NOTICETo be sure your system setup (outdoor unit+indoor unit(s))will work, you have to consult the latest technicalengineering data for VRV IV heat pump.737 7 8 7 73 3 346529 18 HP 10 HP 12 HP 14 HP 16 HP 18 HP 20 HPHeat pumpRXYQ8*/RYYQ8* 1RXYQ10*/RYYQ10* 1RXYQ12*/RYYQ12* 1RXYQ14*/RYYQ14* 1RXYQ16*/RYYQ16* 1RXYQ18*/RYYQ18* 1RXYQ20*/RYYQ20* 1Multi combinationwith 2 outdoor unitsRXYQ22*/RYYQ22* 1 1RXYQ24*/RYYQ24* 1 1RXYQ26*/RYYQ26* 1 1RXYQ28*/RYYQ28* 1 1RXYQ30*/RYYQ30* 1 1RXYQ32*/RYYQ32* 2RXYQ34*/RYYQ34* 1 1RXYQ36*/RYYQ36* 1 1Multi combinationwith 3 outdoor unitsRXYQ38*/RYYQ38* 1 1 1RXYQ40*/RYYQ40* 1 1 1RXYQ42*/RYYQ42* 1 2RXYQ44*/RYYQ44* 1 2RXYQ46*/RYYQ46* 1 2RXYQ48*/RYYQ48* 3RXYQ50*/RYYQ50* 2 1RXYQ52*/RYYQ52* 1 2RXYQ54*/RYYQ54* 3Description Model nameRefnet headerKHRQ22M29HKHRQ22M64HKHRQ22M75HRefnet jointKHRQ22M20TKHRQ22M29T9KHRQ22M64TKHRQ22M75T
