Reducing Energy Consumption Notes 2.0 / 5 based on 1 rating ? Environmental Science/StudiesEnergyA2/A-levelAQA Created by: rosieevieCreated on: 11-01-15 13:36 Double Glazing Windows Reduced air contact - warm and cold air is separated Reduced heat conduction and convection Low conductivity gas e.g. argon is used in between the two sheets of glass An optimal gap size of 16mm Lower temperature gradient 1 of 2 Heat Exchangers Warm stale gas/liquid moves along pipes Countercurrent flow of fresh cold gas/liquid Heat is tranfered from the stale gas/liquid to the fresh gas/liquid Pipes are long - large surface area Pipes have thin walls and are made of good thermal conductor e.g. copper Chamber is insulated to reduce outwards heat loss Cold stale gas/liquid is discharged Fresh warm gas/liquid is used 2 of 2
