The Condenser As A Part Of The System

The condenser operates according to its own rules, but it is also a part of the refrigeration system and therefore interacts with the other components. Except in the low-condensing temperature regions where certain operating limits may apply, it is always … Continue reading

Water Treatment In Evaporative Condenser

Evaporation of spray water is the dominant process of heat rejection in evapoartive condensers. The amount of heat transfer attributible to the difference in dry-bulb temperatures between the condenser tubes and the air is minor. Because the makeup water contains … Continue reading

Supplement Cooling Requirement Provided by Evaporative Condenser

In addition to the major task of condensing refrigerant, evaporative condensers are sometimes called on to cool some other fluid as well. The prime example of this supplementary cooling requirement, and a frequent one, is to cool the oil injected … Continue reading

Size Of Equalizer Lines And Thermosyphon Vapor Lines

Under normal circumstances equalizer lines between the receiver and the inlet or outlet of the condenser can be small, because it is not expected that they need carry high flow rates. They only need to convey a volume flow rate … Continue reading

Draining Condensate – Thermosyphon Oil Cooling

When the oil for screw compressors is cooled by refrigerant circulating by means of a thermosyphon, some of the same principles of condenser draining apply, but there are some additional considerations. A vessel, called the thermosyphon receiver, is needed to … Continue reading

Draining Condensate – Parallel Condensers

A characteristic of industrial refrigeration plants is the use of parallel condensers and compressors. This fact is especially pertinent to ammonia systems, and not always true for halocarbon systems where the oil transfer between parallel units sometimes becomes a problem. … Continue reading

Pressure Profiles In A Condenser

Figure 7.30 shows changes in pressure that develop in a condenser when the equalizer line connects the top of the receiver to the inlet to the condenser. As the condensing refrigerant flows down through the condenser, a pressure drop occurs, … Continue reading

Single Condenser Condensate Draining

The arrangement to insure proper draining of a single condenser depends on the type of receiver. If the receiver is top inlet, good drainage of the condensate results if the vapor in the receiver can flow freely counterflow to the … Continue reading

High Pressure Receivers Piping

The condenser normally drains its liquid refrigerant into the high-pressure receiver, which is a vessel providing storage space for the condensate. The considerations that surround the condenser/receiver subsystem are: – piping arrangements of the receiver – connecting the vapor space … Continue reading

Intentional Subcooling In A Condenser

An objective to be pursued in the next several sections is to effectively drain the condenser of liquid so that the maximum amount of surface area will be available for condensation. Before addressing that goal, however, a technique sometimes used … Continue reading
