REFRIGERATION

Refrigeration is a process which involves the transfer of heat from a low temperature level to a high temperature level. The low temperature level is called the heat source and the higher temperature level is called the heat sink. Because heat itself cannot flow from the low temperature level to a higher temperature, energy must be supplied to the system in order for it to function. Millions in food dollars in food costs and sales each year are influenced by refrigeration, beginning with the receipt of foods and ending with their consumption. Many food purchased have undergone varying types and levels of food processing and thus have established refrigeration needs that must be met in order to maintain them either in a chilled or frozen state. Both the amount of food purchased and type of storage required directly affect the energy needed for refrigeration .thus the physical size of refrigerated units should correspond with the actual needs, if energy is to be used effectively for refrigeration.

Preview of the essay: REFRIGERATION

REFRIGERATION 1.O INRODUCTION This paper is going to discuss on how: • To get information about how energy is used by refrigeration systems to chill and freeze foods and to maintain them in a state with reduced internal product temperature. • To gather information about innovative energy saving features for refrigeration systems being developed for food service industry. • Managerial policies aimed at minimizing energy usage and costs for refrigeration storage while maximizing food quality and safety. 1.2 PRINCIPLES OF REFRIGERATION SYSTEMS Because the energy used by the refrigerated units should be expended to preserve food, some information about how refrigeration actually ...





... Using different colored doors to indicate foods behind the doors. 4. Installing automatic lights to facilitate visibility. 5. Loading proportioned items onto the trays for rapid loading and unloading. 1.5 Conclusion To ensure effectiveness of the refrigerator it is important to verify foods are removed as quickly as possible by opening the refrigerator door for the shortest time feasible.

The principles presented in this work is really interesting. There can be more ideas to crop up if somebody of ingenious mind would read of this.
