The Production of a Suitable Psychrometric Chart for Refridgeration of Cold Rooms

The psychrometric chart contained in this thesis has been prepared to eliminate complicated calculations in refrigeration work within the chart's range. This chart is based on what appears to be the best and most recent data available. The temperature range of the chart is from 0° fahrenheit to 100° fahrenheit. Particular attention has been given to the lower temperature portion of the chart with the hope that it will fill s place which has been somewhat neglected.

It is the writer's wish to acknowledge the help obtained from Charles RR. Lucas' thesis, "Properties of Steam-Air Mixtures." Also the help and valuable suggestions given by Professor W. Re. Woolrich, under whose direction this thesis was prepared.
