2 ooling North Extracted heat delivers free hot water and heating Hot water + Heating South Outdoor Unit Product Range Free heat and hot water production Until now, most commercial buildings have relied on separate systems for cooling, heating, hot water and so on, which results in a lot of wasted energy. An integrated heat recovery system reuses heat from offices, server rooms, to warm other areas or create hot water. Maximum comfort A VRV heat-recovery system allows simultaneous cooling and heating. For hotel owners, this means a perfect environment for guests as they can freely choose between cooling or heating. For offices, it means a perfect working indoor climate for both north and south-facing offices. Improved efficiency In heat-recovery operation the VRV IV is up to 15% more efficient compared to VRV III. In single mode operation, the seasonal efficiency of the system can be even as much as 2% higher - thanks to the variable refrigerant temperature technology - compared to a conventional VRF system. Optimised Partition of Heat Exchanger for highest seasonal efficiency in heat recovery mode Vertically divided heat exchanger with an optimized ratio for mix mode operation. This improves heat recovery efficiency by reducing radiation losses. ooling load Heating load Improved mix mode control Ambient temperature 0% % During heating, the bottom of the heat exchanger stays hot, which minimises frost accumulation and defrost periods. Wide heating operation range -20 WB Heating 15.5 WB VRV IV heat recovery has a standard operation range down to -20 WB in heating. It can also provide cooling down to -20 DB for technical server rooms (field setting). -25 DB -20 DB Technical ooling -5 DB ooling DB 1

3 Advantages of -pipe technology More free heat Daikin -pipe technology needs less energy to recover heat, meaning significantly higher efficiency during heat recovery mode. Our system can recover heat at a low condensing temperature because it has dedicated gas, liquid and discharge pipes. In a 2-pipe system, gas and liquid travel as a mixture so the condensing temperature needs to be higher in order to separate the mixed gas and liquid refrigerant. The higher condensing temperature means more energy is used to recover heat resulting in lower efficiency. Pressure ondensing 55 ondensing 5 Power input 2-pipe system 5 to 15% more efficient in heat recovery mode compared to 2-pipe system Power input Daikin Enthalpy Lower pressure drop means more efficiency Smooth refrigerant flow in -pipe system thanks to 2 smaller gas pipes results in higher energy efficiency Disturbed refrigerant flow in large gas pipe on 2-pipe system results in bigger pressure drop Pressure -pipe VRV H/R 2-pipe system Up to 5% more cooling capacity available at longer piping lengths compared to 2-pipe system Save on refrigerant Pipe length Smaller diameter pipes and -pipe system results in up to % less refrigerant charge compared to 2-pipe systems, saving on refrigerant cost and reducing environmental impact Freely combine outdoor units ombine outdoor units flexibly to reduce your carbon footprint, optimise your system for continuous heating, and achieve the highest efficiency.

This is because our heat recovery system does not need to equalise pressure over the entire system after a change-over. Off BS box

Heights of walls in case of Patterns 1 and 2 Front 1500mm Suction side 500mm Side Height unrestricted Installation space as shown on this drawing is based on the cooling operation at 5 degrees outdoor air temperature. When the design outdoor air temperature exceeds 5 degrees or the load exceeds maximum ability because of much generation load of heat in all outdoor units, take the suction side space more broadly than the space as shown in this drawing. 2. If the above wall heights are exceeded then h2/2 and h1/2 should be added to the front and suction side service space respectively as shown in the figure on the right.. When installing the units most appropriate pattern should be selected from those shown above in order to obtain the best fit in the space available always bearing in mind the need to leave enough space for a person to pass between units and wall and for the air to circulate freely. (If more units are to be installed than are catered for in the above patterns your layout should take account of the possibility of short circuits.). The units should be installed to leave sufficient space at the front for the on site refrigerant piping work to be carried out comfortably. Outdoor Unit Product Range D052
