What does precool mean?
Precool means to cool something before it is required. The verb is used when cooling in advance will improve performance, preserve quality, save time, or make a later task easier. For example, a laboratory may precool an instrument, a restaurant may precool serving plates, and a driver may precool an engine. The prefix pre- indicates that the cooling occurs beforehand, while the final stress normally falls on the second syllable. Although the word can be understood from its components, it is most often encountered in specialist or practical contexts. Outside those settings, the plainer expression "cool in advance" may be preferred. Precooling is distinct from refrigeration intended to preserve an item for an extended period: the immediate emphasis is on preparing something to be used later.
