Ice accumulates on helicopter rotor blades and aircraft propellers causing weight and aerodynamic imbalances that are amplified due to their rotation. Anti-ice systems installed on jet engines or turboprops help prevent airflow problems and avert the risk of serious internal engine damage from ingested ice. These concerns are most acute with ...
Slabs of manufactured ice at the Grimsby Ice Factory prior to being crushed, 1990. An icemaker, ice generator, or ice machine may refer to either a consumer device for making ice, found inside a home freezer; a stand-alone appliance for making ice, or an industrial machine for making ice on a large scale. The term "ice machine" usually refers ...
Stall characteristics of an aircraft with ice-contaminated wings will be degraded, and serious roll control problems are not unusual. The ice accretion may be asymmetric between the two wings which requires calibrating. Also, the outer part of a wing, which is ordinarily thinner and thus a better collector of ice, is likely to stall first.
Ice resurfacers are generally composed of a snow container, hot water tanks, a wash water tank, the conditioner, and a board brush. An internal combustion engine or electric motor of the vehicle is responsible both for propelling the resurfacer and also powering the hydraulics that control the various functions, such as lowering the conditioner or raising the snow dump.
Typically, the equipment for the production, accumulation and supplying of pumpable ice includes an ice maker, a storage tank, a heat exchanger, piping, pumps, and electrical and electronic appliances and devices. Pumpable ice with maximum ice concentration of 40% can be pumped straight from the ice maker to the consumer. The final possible ice ...
The James Harrison Museum committee have acquired land at Rocky Point (the site of the first ice-making machine in the world) and are endeavouring to build a museum there. [ 8 ] The Australian Institute of Refrigeration Air Conditioning and Heating 's most distinguished award is the James Harrison Medal.
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).
Colder temperatures, lower liquid water content, and small droplets favors the forming of rime icing. Clear ice is glossy, clear, or translucent. Compared to rime ice, clear ice forms relatively slowly and tends to appear with warmer temperatures, higher liquid water contents, and larger droplets. Mixed ice is a mixture of rime and clear ice.
