During extreme cold events, you may hear a loud boom and feel like you have experienced an earthquake. However, this event was more likely a cryoseism, also known as an ice quake or a frost quake ...
The name was given because the sound slowly decreases in frequency over about seven minutes. It was recorded using an autonomous hydrophone array. [8] The sound has been picked up several times each year since 1997. [9] One of the hypotheses on the origin of the sound is moving ice in Antarctica. Sound spectrograms of vibrations caused by ...
The 1950s and 1960s saw technical advances like automatic defrosting and automatic ice making. More efficient refrigerators were developed in the 1970s and 1980s, even though environmental issues led to the banning of very effective (Freon) refrigerants. Early refrigerator models (from 1916) had a cold compartment for ice cube trays.
An air conditioner requires work to cool a living space, moving heat from the interior being cooled (the heat source) to the outdoors (the heat sink). Similarly, a refrigerator moves heat from inside the cold icebox (the heat source) to the warmer room-temperature air of the kitchen (the heat sink).
A cryoseism, ice quake or frost quake, [1] [2] [3] [4] is a seismic event caused by a sudden cracking action in frozen soil or rock saturated with water or ice, [5 ...
Common absorption refrigerators use a refrigerant with a very low boiling point (less than −18 °C (0 °F)) just like compressor refrigerators.Compression refrigerators typically use an HCFC or HFC, while absorption refrigerators typically use ammonia or water and need at least a second fluid able to absorb the coolant, the absorbent, respectively water (for ammonia) or brine (for water).
Kelvinator ad from 1920 Kelvinator refrigerator, c. 1926 The enterprise was established on September 18, 1914, in Detroit , Michigan , United States, by engineer Nathaniel B. Wales , who introduced his idea for a practical electric refrigeration unit for the home to Edmund Copeland and Arnold Goss.
