Essential Parts of Refrigeration

The essential parts of a refrigeration plant are:
1.         Refrigeration compressor
2.         Refrigeration condenser
3.         Refrigeration receiver
4.         Refrigeration expansion valve
5.         Refrigeration evaporator coils
6.         Refrigeration suitable pipelines, Refrigeration shutoff valves, Refrigeration gages, Refrigeration thermostats, etc.

Since anhydrous ammonia was the refrigerant most commonly used in earlier times, it will be covered here as it is possible that you may still run across this type of refrigeration system in commercial refrigeration service. The apparatus ordinarily used in an ammonia refrigeration compression system. The refrigeration compressor is merely a pump, which takes the ammonia vapor from the low-pressure side, compresses it, and delivers it to the high-pressure side. The high-pressure side of the plant comprises the refrigeration compressor discharge piping, refrigeration condenser, refrigeration liquid receiver, and liquid piping between the liquid receiver and refrigeration expansion valve. The pressure side comprises the piping leading from the expansion valve to the refrigeration evaporator coil, evaporator coil, and piping leading from the evaporator coil to the refrigeration compressor suction side. The pressure at the low side of the system remains practically constant and is indicated by the back-pressure gage at the suction side of the compressor. In a refrigeration plant of this type, ammonia vapor superheated by the work of compression passes through a condenser where cooling water lowers its temperature until it condenses into liquid ammonia. The liquid leaving is sub cooled to 82°F, a temperature that is slightly below that of condensation (86°F). The expansion valve comprises the dividing point between the high- and the low-pressure sides of the system. The function of the refrigeration expansion valve is to regulate the flow of ammonia from the high- to the low-pressure side. The heat absorbed from the refrigerator by the liquid ammonia in the evaporating coils causes the liquid to boil until vaporization is complete and vapor is slightly superheated. After the liquid refrigerant has produced its refrigerating effect in the evaporating coils, the gas is compressed to a suitable pressure. Ammonia gas, for example, when compressed to 154.5 psig, will condense at a temperature of 86°F. Cooling water of a lower temperature than 86°F is usually available for abstracting the latent heat from the vapor thus converting it to a liquid (i.e., condensing it). To obtain this pressure of 154.5 psig this system requires the use of a compressor with some form of motive power and also a condenser in which the gas may be liquefied. The regulating or refrigeration expansion valve releases the liquid from the condenser or its accompanying liquid container or receiver and controls the pressure at which the evaporation and consequent refrigeration takers place. The refrigeration expansion valve may be hand or automatically controlled, and its opening or closing allows more or less refrigerant to pass to the low-pressure side of the system. The liquid refrigerant in the low side is evaporated by the heat of the substance being cooled, and the resulting gas is pumped away by the refrigeration compressor. To replace this, enough refrigerant is allowed to pass from the high side through the refrigeration expansion valve to maintain a constant pressure and temperature in the low side. The refrigeration compressor brings the low-pressure ammonia gas from the cold side, compresses it, and discharges it to the high-pressure side. This increase in pressure raisers the boiling or, in this case, condensing temperature of the gas so that comparatively warm cooling water readily condenses the compressed gas again to a liquid. This liquid ammonia is usually collected in a receiver, and from there it is passed through the expansion valve. The reduction in pressure lowers the boiling point of the ammonia, causing it to evaporate.
