Unit 2
Food Processing & Preservation by Refrigeration
Candy – manufacture and storage conditions, Beverage processing -beer, wines and carbonated drinks – refrigeration in food preservation, processing control and storage. meat products – chilling, processing & storage conditions poultry products – chilling, freezing & storage conditions. Fishery products -processing, preservation and transportation of fresh and frozen fish and their products – icing of fish individual quick freezing, contact plate freezers, air – blast freezers and immersion freezers. Fruits and vegetables – storage requirements of common fruits & vegetables, controlled atmosphere storage suitability of freezing and dehydro-freezing – fruits ripening. Dairy products – pre cooling for separation and blending, pasteurization process, equipments used. Butter separation & storage – Ice-cream manufacture – process, processing temperature and storage conditions.
Unit 3
Commercial refrigerators, cooling load and blood bank refrigerators
(A ) Commercial refrigerators: Commercial refrigerators – construction and working of reach in refrigerators, walk in coolers and display cases.
(B ) Cooling load and freezing load calculations for design of freezer and cold storages: Cooling load calculation – common sources of heat load – wall gain load (Transmission load), product load – sensible latent heat and respiration load, air change and infiltration load, miscellaneous load due to electric motors, lighting, people working inside storage rooms etc – equipment running time, chilling rate factor, use of safety factor, insulation of cold storage walls. Refrigeration load in freezers and freezing time calculations. Problems – problems on cooling load and freezing load calculations. Use of charts and tables allowed in Board Examinations.
( C ) Blood Bank Refrigeration and Preservation of tissue and virus: Blood preservation – storage temperature and equipments. preservation of tissues – storage temperature Preservation of virus – storage temperature and applications. Effects of refrigeration on blood, tissues and virus.

Unit 5
Transport Air conditioning
(A ) Automobile Air conditioning: Automobile air conditioning – source of power – factors affecting cooling load – out door conditions, air leakage into passenger space, number of occupants, sun load, fresh air, variation of cooling load with automobile speed. Basic components of automobile air conditioning – compressor, magnetic clutch, condenser, receiver and drier, expansion valve, evaporator, suction throttle valve, air distribution in passenger cars, car insulation, capacity and weight of air conditioning system. Design considerations in bus air conditioning – capacity and weight of air conditioner.
(B ) Railway air conditioning: Location of different air conditioning equipments, types of power system used in axle driven system, engine driven compressor system electro mechanical system. Compression cooling system and air distribution.
(C ) Marine Air conditioning: Design requirements, ambient and indoor conditions. Special problems in ship air conditioning – air circulation, air conditioning machinery, safety of ships, ventilation requirements, air distribution methods. Air conditioning system used for ships – single zonal central system, multi zone central system, terminal reheat system. Control of design conditions – volume control reheat control, air mixture control.
(D ) Refrigerated trucks and trailers: Temperatures maintained for cold foods and frozen foods, Types of refrigeration system – product sub cooling, using water ice, water ice in bunker with forced air circulation, using dry ice Using liquid nitrogen or Carbondi-oxide spray, Eutectic plates with station charging, eutectic plates with vehicle-mounted condensing unit, mechanical refrigeration with independent engine or electric motor, mechanical refrigeration deriving power from vehicle engine or transmission.
