What can be used to maintain the head pressure of a system with an air cooled condenser?
A water regulating valve helps to maintain a system’s head pressure by modulating the flow of refrigerant through the condenser. The desired water flow through a condenser connected to a recirculating water system is three gallons per minute.
What 3 materials are condensers made of?
5 Condensers The most common tube materials in a condenser are copper–nickel alloys, brass, titanium, stainless steel, and ferritic stainless steel.
Why are some water cooled condensers cleaned with brushes and others with chemicals?
Why do some condensers have to be cleaned with brushes and others with chemicals? Straight condensers can be cleaned with brushes and coiled condensers have to be cleaned with chemicals. After heat is absorbed into a condenser medium in water cooled condenser the heat is deposited in one of two places.
How does condenser flooding maintain head pressure in low ambient?
How does “condenser flooding ” maintain head pressure in low ambient ? Refrigerant takes up space in the condenser tubing, forcing head pressure up. How does a technician make sure a condenser is clean ? The technician thoroughly cleans it himself .
What type of condenser has the lowest operating head pressure?
The type of condenser that has the lowest operating head pressure is the _______cooled condenser.
Why do some condensers have to be cleaned with brushes?
Why do some condensers have to be cleaned with brushes and other with chemicals ? Some condenser tubes are not straight and will not allow brushes to pass through them. After heat is absorbed into a condenser medium in a water -cooled condenser, the heat can be deposited in one or two places .
Which of the following condensers is the most efficient?

| Which of the following condensers is the most efficient? | D. Water-cooled counterflow |
What are the 4 types of condensers?
The major types of condensers used are (1) water-cooled, (2) air-cooled, and (3) evaporative. In evaporative condensers, both air and water are used. Three common types of water-cooled condensers are (1) double pipe, (2) shell and tube (as shown in Fig.
