6.1WATER SYSTEM

A.MOTOR/PUMP ASSEMBLY: the motor/pump assembly circulates chilled fluid to the process loop. The pump assembly is built of brass to maintain water quality.

6.2REFRIGERATION SYSTEM

A.COMPRESSOR: hermetic compressors take low pressure/low temperature refrigerant gas and compress the gas into high pressure/high temperature gas).

B.AIR COOLED CONDENSER: the air cooled condenser removes BTUs from the compressor refrigerant gas. The action causes the gas to “condense” into a liquid state still under high pressure. Air flow across the condenser is achieved via a motor driven fan.

C.FILTER-DRIER:the filter-drier removes contaminants and moisture from the liquid refrigerant.

D.LIQUID RECEIVER: serves as a collection tank for high pressure liquid refrigerant to ensure total charge at all times.

E.REFRIGERANT SIGHT GLASS: the refrigerant sight glass indicates refrigerant charge and moisture content. Refrigerant charge is determined by a clear liquid flow. Bubbles indicate low refrigerant. Moisture content is indicated by the color of the element. Element color is normally green. If the color of the element is chartreuse or yellow, the system has been contaminated with moisture. In such case, the filter-drier must be replaced. The replacement of the filter-drier must be completed by a qualified refrigerant service technician.

F.EXPANSION VALVE: the expansion valve throttles flow of refrigerant liquid into the evaporator and creates a pressure drop in the refrigerant system that allows the liquid refrigerant to “boil off” inside the evaporator.

G.EVAPORATOR: the evaporator is a tube in tube heat exchanger where the refrigerant liquid is allowed to evaporate (boil off) to absorb heat (BTU) from the process fluid. As the heat is absorbed, the process fluid is chilled.

H.HIGH/LOW PRESSURESTATS: the high/low pressurestats protect the refrigeration system from unsafe operating levels. The high pressure switch is factory set to open at 325 psi and protects the refrigeration components and personnel from potential damage of injury from excessive high pressure. The high pressure safety must not be altered in the field for any reason. The low pressure switch is factory set to open at 58 psi and to close at 63 psi. The low pressure switch protects the chillers from possible damage due to low operating pressure. The low pressure switch is field adjustable for setpoints below 48°F.
