Air sourceheat pumpsHigh output air source heatpumps for outdoor installationDimplex high output air source heat pumpsexpand the scope of the applications for highefficiency heating solutions with a range ofincreased output models ranging from20-40kW.Optimised twin compressor operation allowsbuildings with high heat consumption tobe catered for, such as offices, schools,hotels or retail outlets. High output heatpumps are also ideal for multiple occupancybuildings such as flats and apartments wherecentralised heat pump systems are able toprovide a building-wide heating solution.Parallel operation for higher total capacityMultiple Dimplex heat pumps can be connected together inparallel to provide a highly cost effective solution where very highcapabilities are required.The WPM heat pump manager controls and optimisesperformance of the system.18Outdoor Installation
High output airsource heat pumpsLA ASThe Dimplex LA AS range of high output 3phase air source heat pumps provide a flexiblerange of solutions for higher capacity heatingsystems.All models utilise a wall mounted WPM 2007heat pump manager, allowing independentcontrol over multiple heating circuits at differingflow temperatures.Twin compressor operation enables thesemodels to flexibly and efficiently adapt tofluctuating heat demand by automaticallyswitching between single and dual compressormodes depending on the outside temperatureand heat demand of the building.Range featuresLA 20-28 AS• Range of 4 models with nominal heatingcapacities from 20-40kW.• Variable heating water flow temperatures from35°C-55°C with weather compensation.• Intelligent switching between single and dualcompressor modes, maximising efficiency andcompressor duty cycle.• WPM 2007 heat pump manager.• Suitable for use with under floor heating, radiatoror fan coil systems and to provide hot water.• Three phase electrical connection, with electronicsoft start to reduce start current loads.• Optional flexible expansion for bivalent orbivalent-renewable operating mode and fordistributed systems with unmixed and mixedheating circuits.• LA 40 AS modes incorporates horizontal air flowcircuit, minimising installation space requirements.LA 40 ASModel LA 20 AS LA 24 AS LA 28 AS LA 40 ASConnection Voltage (V) 400 400 400 400Maximum flow Temperature (°C) 55 55 55 55Heat Output A7/W35 (kW)1 compressor 9.8 13.1 14.2 20.22 compressors 16.6 24.8 25.8 36.3CoP A7/W351 compressor 3.2 3.4 3.1 4.72 compressors 3.1 3.6 3.4 4.5Please see page 44 for full technical specifications.LA AS19
