Carbon Emissions - The table (right)compares the carbon emissions ofGHP 560 with a Condensing Boiler(80% efficiency) and a conventionalVRF outdoor unit (electric powered).The Carbon Intensity is the amount ofCarbon emitted per KW hour of usefulheating or cooling output.The GHP comparisons on heating arerated at ISO standard conditions, and atlower ambient conditions, which illustratethe advantages of recovering the wasteheat from the engine coolant system.Running Costs - comparisons are basedon the cost per KWh of cooling andheating output.The electricity and gas tariffs are statedbelow, and are representative ofcommercial supply contracts. VRF(Electric powered systems) are basedon COP of 2.9 (rated at 7ºC ambient)and EER of 2.7. The COP/EER at lowerambient conditions are typical of VRF,and are adjusted to take account of thereduced performance at lower ambientconditions and the reduction of usefulheat output due to defrost periods. Thepower consumption figures are basedon heating performance of 67.0KW,cooling 53.0KW. The calculations donot take into account the indoor units.Gas commercial tariff = 1.55penceper KWh (incl 0.15p CCL),Electricity commercial tariff = 5.40pence/KWh (incl. 0.43p CCL).The example is based on the GHP560rated at 67.0KW heating, 56.0KWcooling.Carbon EmissionsCarbon Intensity KgC/KWh Ambient Temp 35ºC 7ºC 0ºC -7ºC -15ºCCooling Operation VRF Electric powered 0.043GHP 0.053Heating Operation VRF Electric powered 0.042 0.051 0.049 0.059GHP 0.043 0.043 0.044 0.046Condensing Boiler 80% efficiency 0.066 0.066 0.066 0.066Running Costs (Cost: pence/KWh of cooling and heating output)Ambient 35ºC 7ºC 0ºC -7ºC -15ºCCooling VRF Electric EER 0.043Power Input KW 20.38Cost p/KWh Output 2.00GHP Gas Fuel Input KW 0.053Electricity Input KWCost p/KWh Output 1.67Heating VRF Electric COP 2.90 2.22 2.28 1.91Power Input KW 23.10 30.12 29.33 35.06Cost p/KWh Output 1.86 2.43 2.36 2.83GHP Gas Fuel Input KW 51.9 51.9 52.9 55.9Electricity Input KW 1.18 1.18 1.18 1.18Cost p/KWh Output 1.30 1.30 1.32 1.32Heating - Condensing Boiler Cost p/KWh 1.94 1.94 1.94 1.9480% efficiencyGHP SpecificationModel Ref: GHCP450HMTE4 GHCP560HMTE4Cooling Performance KW 45.0 56.0Heating Performance KW 53.0 67.0Dimensions H x W x D mm 2135 x 1750 x 950 2135 x 1750 x 950Weight Net Kg 910 920Power Supply 415V 3 ph 50HZ 415V 3 ph 50HZRunning current Cooling A 2.6 2.6Heating A 1.9 1.9Power consumption Cooling KW 1.62 1.62Heating KW 1.18 1.18Start current A 19 19Gas FuelNatural gasGas Fuel consumption Cooling KW 44.3 54.6Heating KW 41.5 51.9Engine type 4 cylinder, 4 cycle, water cooled, OHVEngine size cc 2237Engine speed range rpm 890 to 2375Engine starterAC/DC variable type DC statorRefrigerant pipe connections o.d. 5/8" flare 3/4" flareo.d. 1 3/8" brazed 1 1/2" brazedRefrigerant R407C Kg 17.5 18.0Gas mains supply connection mm 25 25Drain for exhaust condensate mm Flexible hose o.d. 18.2 i.d. 12.2Compressor - open type CR5445HVR CR5453HVRCompression volume cc 454 528Condenser Fans Propellor fan x 2Fan motor type3-phase inductance motor 6-poleFan motor power KW 0.25 x 2 0.45 x 2Connectable indoor units 1 to 20Connectable capacity 22.5KW to 58.5KW 28.0KW to 72.8KWTechnical Specification
Indoor UnitsThe internal units used on GHP systems are identical to those used on KX/KXRVRF systems. The control language is the same, and all remote/centralized controlsare also the same.A total of 20 indoor units can be connected to each GHP, and can be controlledindividually, in heating or cooling mode, dependent on the mode operation ofthe GHP system, i.e. it is not possible to have some units on cooling while othersare on heating. The internal units are connected by two refrigerant pipes withbranch pipe kits or headers branching from the main 2-pipe circuit.FDT 4-Way Cassette 2.8KW to 16.0KWIntegral Condensate Lift PumpFDTQ Cassette – Single Discharge 2.2KW to 4.0KWIntegral Condensate Lift PumpFDQM Compact Ducted 2.2KW to 4.0KWIntegral Condensate Lift PumpFDTS Cassette – Single Discharge 4.5KW to 8.0KWIntegral Condensate Lift PumpFDUM Ducted Horizonta 4.5KW to 16.0KWIntegral Condensate Lift PumpFDR Ducted Cassette 4.5KW to 16.0KWIntegral Condensate Lift PumpFDK Wall Mounted 2.2KW to 8.0KWOptional Condensate Lift PumpFDFL Floor Mounted 2.8KW to 8.0KWFDFU Concealed Floor Unit 2.8KW to 8.0KWFDE Ceiling Mounted 3.6KW to 16KWFDTW 2-Way Cassette 2.8KW to 16KWIntegral Condensate Lift Pump
