AIR HANDLING UNITS (AHU’S)XBOXER PERFORMANCETECHNICAL INFORMATIONHOW MUCH ENERGY DOES THE EXCHANGER SAVE? Heat recovery systems reduce this heat loss by transferring the heat contained in the extracted air to the supply air.In a building ventilation system that does not have a heat recovery facility, the A system with a heat exchange efficiency of 70% will recover 70% of the energyair used for ventilation enters the building at the external ambient temperature, supplied therefore reducing the power required.and is expelled from the building at approximately room temperature. There is of course an energy penalty in terms of the additional pressure loss dueThis increase in temperature may be caused directly by heaters intended to raise to the heat exchanger element itself, and this needs to be minimized by optimalthe air temperature to a suitable value for supply to occupied rooms, or indirectly selection of the system fans, motors and control systems. Generally, it can beby heat transfer from the buildings internal surfaces and existing air content. demonstrated that the additional system losses are small compared to theThis “ventilation heat loss” can be quantified as: reduction in heating load.Air Mass Flow rate (kg/s) (Air volume flow rate (m3/s) x Air density (kg/m3) ELECTRIC HEATING x Temperature difference (deg C) [Ta internal – Ta external] To find the final supply air temperature when an electric heater is required, use x Specific Heat Capacity of air (kJ/kg deg C) the following table:(Approx = 1)Using some typical (heating season) values, the power required to heat unit airflow, and which is then lost is:= 1m3/s x 1.2 kg/m3 x (22-6) deg C x 1= 19.2 kWAir Intake Air Electric heater kWVolume TemperatureFlow rate (deg C) 2 3 6 9 12 15 18 21 24 27 54m3/s Supply Air Temperature (deg C) -5 12 20 0 17 250.1 5 22 30 10 27 35 15 32 -5 8 20 33 0 8 13 25 380.2 5 13 18 30 10 18 23 35 15 23 28 -5 8 14 20 26 33 0 6 13 19 25 31 380.4 5 9 11 18 24 30 36 10 14 16 23 29 35 15 19 21 28 34 -5 8 12 16 20 24 28 33 0 8 13 17 21 25 29 33 380.6 5 8 9 13 18 22 26 30 34 38 10 13 14 18 23 27 31 35 39 15 18 19 23 28 32 36 -5 8 11 14 17 20 23 0 6 9 13 16 19 22 25 280.8 5 7 8 11 14 18 21 24 27 30 33 10 12 13 16 19 23 26 29 32 35 38 15 17 18 21 24 28 31 34 37 -5 5 8 10 13 15 18 40 0 5 8 10 13 15 18 20 231 5 7 8 10 13 15 18 20 23 25 28 10 12 13 15 18 20 23 25 28 30 33 15 17 18 20 23 25 28 30 33 35 38 -5 5 7 8 10 25 0 5 7 8 10 12 13 15 301.5 5 67 8 10 12 13 15 17 18 20 35 10 11 12 13 15 17 18 20 22 23 25 40 15 16 17 18 20 22 23 25 27 28 30 -5 5 6 18 0 5 6 8 9 10 11 232 5 6 6 8 9 10 11 13 14 15 16 28 10 11 11 13 14 15 16 18 19 20 21 33 15 16 16 18 19 20 21 23 24 25 26 38 -5 10 0 5 6 7 8 153 5 6 6 7 8 8 9 10 11 12 13 20 10 11 11 12 13 13 14 15 16 17 18 25 15 16 16 17 18 18 19 20 21 22 23 30Download specification from www.nuaire.co.uk/specifications nuaire.co.uk 77
