In non-cyclic refrigeration, cooling is accomplished by melting ice or by subliming dry ice (frozen carbon dioxide). These methods are used for small-scale refrigeration such as in laboratories and workshops, or in portable coolers. Ice ow...
Probably the most widely used current applications of refrigeration are for air conditioning of private homes and public buildings, and refrigerating foodstuffs in homes, restaurants and large storage warehouses. The use of refrigerators i...
The first known method of artificial refrigeration was demonstrated by William Cullen at the University of Glasgow in Scotland in 1756. Cullen used a pump to create a partial vacuum over a container of diethyl ether , which then boiled , a...
The use of ice to refrigerate and thus preserve food goes back to prehistoric times.Through the ages, the seasonal harvesting of snow and ice was a regular practice of most of the ancient cultures: Chinese, Greeks, Romans, Persians. Ice an...
Advantages Capable of large refrigerating loads at lower initial purchase and operating cost. Very efficient Very compact system for small to very large heat loads Cycle can be reversed for heat pump operation Disadvantages Parts can wear...
Advantages Light weight and compact for very small heat loads. No moving parts, eliminating vibration, noise, and problems of wear. Reversing the direction of current transforms the cooling unit into a heater. Operates in any orientation.N...
With the application of heat at the generator, ammonia vapor is driven from the solution. This hot vapor rises into the separator and a portion of the water condenses and flows by gravity into the absorber. The hot ammonia vapor continues...
Snowbird Environmental Systems of Jacksonville has won a maximum $9 million contract for landing craft air cushion air conditioners for the Navy. The work is expected to be completed by Aug. 5, 2013, the Defense Department said in a news r...
Agricult ure Solar integrates their multiple technologies for the advantage of cold storage owners. Our systems combine improved efficiency, energy generation, and power storage to give back the power to the owner, says Seth Pepper of Agri...
