摘要

The first air conditioning probably started with early man when he moved inside a cool, dark cave to escape the summer heat and to protect himself from the winter cold. Humans have continually searched for ways to keep cool in the summer, from indulging in Roman baths to siting castles for cross-ventilation to using cardboard hand fans during many summer church services. It has only been in the twentieth century -less than 100 years - that air conditioning as we know it now has been in use. Today, we find the benefits of air conditioning to be much more than personal comfort - it is necessary for improving productivity in the workplace, making possible good medical/health service and preserving fresh and frozen foods. In less than 100 years, air conditioning has become a necessity in our lives.
