42 Sizing Of A Small Capacity Refrigerat ion Installation (7.10kw) For The Conservation Of Fish At The Thinwgul Market In Mamou In The Republic Of Guinea Abstract: The objective of this research is to size a refrigeration installation adaptable to the site of the Thinwgul market 1.5 km from downtown Mamou with an area of 4269m2 in the Republic of Guinea for the conservation of fish. During this study, we determined the main parameters essential for the proper functioning of the cold room for conservation, which are among others: compressor (3kW), condenser (9.135kW and 9.67 m2); evaporator 59 m2); regulator (0.38.10 -4m3/h and 8.7bar); pipes: suction (21,090.10-4 m2), discharge (2,603.10-4 m2); cooling performance coefficient: real (3.15 and 4.06), ideal (4.71 and 4.89). Then, according to the analysis of these main results obtained during this study, namely mainly the coefficients of real and ideal refrigeration performance, this suggests a proposal for a refrigeration system with a power of 7.10kW. The refrigerant used in this study is Hydrochlorodifluorocarbon (CHF2Cl) or refrigerant 22 (R22)
