Lubrication Cycle

The oil pump and oil reservoir are contained within the unishell. Oil is pumped through an oil filter-cooler that removes heat and foreign particles. A portion of the oil is then fed to the compressor motor-end bearings and seal. The … Continue reading

Dehydrator Cycle

The dehydrator removes water and noncondensable gases. It indicates any water leakage into the refrigerant (see No. 6 in Fig. 8-11). This system includes a refrigerant-condensing coil and chamber, water drain valve, purging valve, pressure gage, refrigerant float valve, and … Continue reading

Motor-Cooling Cycle

Refrigerant liquid from a sump in the condenser (No. 24 in Fig. 8-11) is subcooled by passage through a line in the cooler (No. 27 in Fig. 8-11). The refrigerant then flows externally through a strainer and variable orifice (No. … Continue reading

Refrigeration Cycle

The machine compressor continuously draws large quantities of refrigerant vapor from the cooler, at a rate determined by the size of the guide-vane opening. This compressor suction reduces the pressure within the cooler, allowing the liquid refrigerant to boil vigorously … Continue reading

HVAC Chillers

A chiller is part of a condenser. Chillers are used to cool water or brine solutions. The cooled (chilled) water or brine is fed through pipes to evaporators. This cools the area in which the evaporators are located. This type … Continue reading

Water-Cooled Condensers

Water is used to cool condensers. One method is to cool condensers with water from the city water supply and then exhaust the water into the sewer after it has been used to cool the refrigerant. This method can be … Continue reading

Air-Cooled Condensers

Figure 8-1 illustrates the refrigeration process within an air-cooled condenser. Figure 8-2 shows some of the various types of compressors and condensers mounted as a unit. These units may be located outside the cooled space. Such a location makes it … Continue reading
