Use the House illustrations Index pages to find specific diagram pictures. For example, if you would like to find illustration diagrams of "electrical wires", you could use the find feature of your web browser to search for "electrical" or "wires" on the House illustrations Index pages. You can then click the linked text to open the pages with those pictures. Also, you can use the House Illustration navigation menus for the specific category to find and view the diagram pictures.

 

AIR CONDITIONING - THE BASICS
1200 Moving heat from the inside to the outside
1201 Heat transfer at the inside coil
1202 Evaporator coil - collecting hot air inside the house
1203 The Freon gas goes outside
1204 Compressors - heating up Freon gas
1205 Condenser coil - exhausting hot air to the outside
1206 Hot liquid back to the house
1207 Expansion devices - cooling hot liquid Freon
1208 Air conditioning - schematic of system
1209 Latent heat of vaporization
1210 Discharging condensate
1211 High pressure and low pressure sides
1212 Inspecting the condenser unit
1213 Air conditioning - schematic of system
1214 Water-cooled air conditioning - schematic of system

AIR CONDITIONING - AIR CONDITIONING CAPACITY
1215 One ton of cooling
1216 How much area can one ton cool?
1217 Larger ducts are required for air conditioning
