Refrigerator for cooling beer barrel, has analog or digital thermometer to determine outer temperature of refrigerator, where outer temperature is permuted to determine inner temperature and beer temperature
摘要
<p>The refrigerator has an analog or digital thermometer to determine outer temperature of a refrigerator. The outer temperature is permuted in order to determine the inner temperature of the refrigerator and beer temperature. The refrigerator implements compressor technique and absorption and adsorption technique. A hygrometer determines relative air humidity, and a barometer determines air-pressure differences.</p>
