Compressor and a metering device to work together to create a zone of high pressure and low pressure zones in one system. They allow the same refrigerant, which evaporates at 40F condense at 120F. These two devices note dividing points between the high pressure and low pressure, or simply high side and low side of the refrigeration system.
Looking at the diagram of the system, we consider the components on the high side and low side of the system. Find each of those elements specified in the scheme, as discussed. Compressor takes refrigerant gas at low pressure and temperature (about 40F) and compresses it. Compressor discharge on the high side of the system. The compressor has a high blood pressure about 263 PSIG and temperature up to 170F. Also on the high side, interconnecting tubing ("line"), which carries the hot gas from the compressor, the condenser coil. This is called hot gas line.
Condenser coil on the high side, as in the liquid line, which connects the condenser metering device. Refrigerant enters the dispenser at high pressure and temperature, but leaves at low pressure and temperature.
The entrance dispenser on the high side, but the outlet is on the lower side of the system. The evaporator is also on the low side of the system, as the suction line connecting the evaporator with the compressor inlet. Absorption, or on the input side of the compressor is the last item on the low side of the system. The main components of the cooling system:
evaporator
capacitor
compressor
dispenser for liquids
Finally, major, key components of the mechanical refrigeration system are:
Evaporator to absorb heat in the refrigerant system.
Capacitor discharge of heat from the refrigerant.
Compressor to create the necessary pressure to force the heat flow "up the hill."
Fluid metering device to regulate the flow of refrigerant and, in the process, to establish two levels of pressure.
Pipes are used for connecting the components and keep refrigerant closed from the pollution outside the system. Many accessories are available for the refrigeration system, but they are not essential to its functioning. They will be considered in a separate module. Now let's take a closer look at each of these four main components.
Four main components can be divided into two groups, each of which contains two points. The first group is the heat exchangers; these heat transfer. Evaporator and condenser are in this group. The second mechanical devices that regulate the refrigerant pressure and flow within the system. Compressor and liquid metering device belonging to this group...
