Experiment Background
|
In the present context the energy demand is increasing with increasing the population and improvement in the living standard. It is the crucial input to the social, economic, industrial and technological development of any country. The rapid growth in world population and the economy, especially in developing countries, total world energy consumption has increased and is projected to increase by 71% during 2003-2030. The energy is harvested from conventional fossil fuel and due to its excess consumption, the greenhouse gases are releases to the lower atmosphere. This results in global warming and acid rain. This is the reason why legislative initiatives as well research activities aim at the utilization of systems, which lead to an increasing energy saving and use of renewable –energy.
The refrigerating system is designed to store certain goods like food stuffs, fruits, vegetables and dairy products within well-defined temperature range and relative humidity (RH). The temperature humidity conditions maintained inside a refrigerating system depend upon the type of product stored inside it, e.g. vegetables require the maintenance of a temperature 0 to 5 (273 K to 278 K) with high RH of 80 to 90%, 4 to 5 (277 K to 278 K) for milk processing, -25 to -30 (248 K to 243 K) for quick freezing of fish, -20 to -45 (253 K to 228 K) for chlorine liquefier, etc. Thus, the conditions required for storage can be divided into the following two categories: (a) Cold storages for products which are to be maintained at temperatures of 0 and above and (b) Cold storages for products which are to be maintained at temperatures below 0
It may be noted that the refrigeration does not improve the quality of food products; it only slows down its deterioration. During storage, the fresh vegetables and fruits produce ‘’heat of respiration’’. Thus, the refrigeration system must be designed to take care of this load in addition to the usual heat loads, load due to heat released on defrosting etc.
