can NOT be OPTIMIZED for both evaporators. The FFC air and the FZC air circulate separately. However‚ as only ONE COMPRESSOR provides refrigeration for both compartments‚ the TEMPERATURE CONTROL is also rather COMPLEX. DUAL-LOOP DUAL-EVAPORATOR SYSTEM (Sub-Zero/Viking/Bosch/Liebherr (?) ) TWO COMPLETELY SEPARATE refrigeration loops provide refrigeration for each compartment. The FFC evaporation temperature is higher than the FZC evaporation temperature and this increases the system

PREPARATION FOR: "MACPHERSON REFRIGERATION LIMITED" CASE Read the case‚ and answer the following questions: 1. Search in the library (books on Operations Management or Production Management)‚ to find the main components of the “Aggregate Production Planning” problem and briefly describe which are “pure strategies” and “mixed strategies” to solve this problem. The aggregate demand is the total demand for all products/services produced by a production facility without considering size‚ models

To get an understanding and appreciation of the value of refrigeration and how it works‚ the history and mechanical engineering theory of refrigeration will be briefly explained at the beginning. 2.0 The History of Refrigeration. Before 1938 refrigeration did not really exist. Wet ice and salt were used to preserve poultry‚ dairy products and meat. People used “larders” in their houses to keep the meat

INTRODUCTION Vapour absorption refrigeration system is one of the oldest methods of producing refrigerating effect. John Leslie in 1810 kept H2SO4 and water in two separate jars connected together. H2SO4 has very high affinity for water. It absorbs water vapour and this becomes the principle of removing the evaporated water vapour requiring no compressor or pump. H2SO4 is an absorbent in this system that has to be recycled by heating to get rid of the absorbed water vapour‚ for continuous

of Refrigeration[16]: Mechanical refrigeration is done by three processes that are circulation‚ evaporation‚ and condensing a fixed supply of refrigerant in a closed system. Evaporation takes place at a low temperature and low pressure while condensation occurs at a high temperature and high pressure. Thus‚ it is possible to transfer heat from an area of low temperature (i.e.‚ water storage tank) to an area of high temperature (i.e.‚ environment). Regarding to the fig 3.1‚ beginning the cycle at
