  • 1. Cooling Energy (BTU) MeteringKamstrup Middle East FZCPO BOX 73030DubaiUnited Arab EmiratesJarmo HeikkinenGeneral ManagerTel:+971 4 4537337E-mail: jjh@kamstrup.comwww.kamstrup.com
  • 2. Why to use individual metering?BTU meters cost money (additionalcost to my project)BTU meters are not mandatory (Ican proceed without meters)Using BTU meters brings me extrawork (I need to create tariffstructure)Somebody needs to operate the BTUmeter system (extra personnel)

  • 5. Why to use individual metering?BTU meters save money • 30% less energy consumption according to experience from real life in EuropeBTU meters save energy • 30% less cooling power capacity investmentUsing BTU meters enable fair billing • everyone pay for what they really decide to consume • 1oC ~ 5% energy use !BTU meter system detects failures inthe cooling system • leakages of water • leakages of energy • low delta T indication
  • 6. Why to use individual metering? BTU Meters give confidence to own consumption • according to studies made in the UAE customers want to have their own meter Actual consumption data provides valuable feed back to used design recommendations Automatic Meter Reading system enables effective meter reading with minimum personnel • exact monthly reading provides accurate statistics (+/- 1½ day = 10% in monthly reading!) • tenant is moving in/out • tenant is asking help for his problems
  • 7. Thermal Energy Meter (BTU Meter) Supply sensor Flow meter Consumer Chilled Water Supplier Calculator Return sensor
  • 8. Thermal Energy Meter’s Accuracy ΔΘ = temperature difference between supply and return lines qp = permanent (nominal) flow q = actual flow -> Accuracy of a meter is not constant but depending on: 1. Temperature difference of application (Bigger temperature difference gives better accuracy) 2. Sizing of the flow meter (Smaller meter gives better accuracy)
  • 9. Advantages of modern metersMechanical Meters Rotating impeller inside the flow meterStatic Meters Ultrasonic, based on ultrasound Magnetic Inductive, based on magnetic induction Oscillator, based on water oscillation in flow channel
  • 10. Operating Principles t2 E = ∫ k ⋅ q ⋅ Δθ ⋅ dt U = B⋅d ⋅v t1 q = v ⋅π ⋅ d 2 / 4 Energy = V x ΔΘ x k. π ⋅d q =U ⋅ 4B t 1 Δt 1 2 2
  • 11. Advantages of modern metersStatic Meter’s Benefits over Mechanical Meters Measuring ratio 1:200 i.e. Max flow is 200 times bigger than min flow (1:50 for mechanical meters) High accuracy on wide measuring area Inherent to pressure shocks Limited maintenance need Long life timeUltrasonic Meter’s Benefits over Magnetic Inductive Meters Not sensitive for Fe-related impurities Keep high accuracy in real applications (including impurities in water) longer time without maintenance
