Heat Exchanger and Condenser In addition to heating up or cooling down fluids in just a single phase, heat exchangers can be used either to heat a liquid to evaporate (or boil) it or used as condensers to cool a vapor and condense it to a liquid. In chemical plants and refineries, reboilers used to heat incoming feed for distillation towers are often heat exchangers. Heat Exchangers

Heat Exchanger Definition
Heat exchanger n. A device, such as an automobile radiator, used to transfer heat from a fluid on one side of a barrier to a fluid on the other side without bringing the fluids into direct contact.
A heat exchanger is a device built for efficient heat transfer from one fluid or gas to another, whether the fluids are separated by a solid wall so that they never mix, or the fluids are directly contacted.[1] They are widely used in petroleum refineries, chemical plants, petrochemical plants, natural gas processing, refrigeration, power plants, air conditioning and space heating. 热量从一个液体转递到另一液体，但两者液体是相互分隔开来的。 4
Condenser Definition Device for reducing a gas or vapour to a liquid. Condensers are used in power plants to condense exhaust steam from turbines and in refrigeration plants to condense refrigerant vapours, such as ammonia and Freons. The petroleum and chemical industries use condensers for hydrocarbons and other chemical vapours. In distillation, a condenser transforms vapour to liquid. All condensers work by removing heat from the gas or vapour. In some, the gas passes through a long tube of heat-conductive metal, such as copper (usually arranged in a coil or other compact shape), and heat escapes into the surrounding air. Large industrial condensers use water or some other liquid to remove the heat. The term condenser also refers to a device attached to carding machines in textile factories to collect fibres into roving for spinning machines 将蒸汽变成液体。

Suggestion for expander lubrication
Each time two expanders for the working of one air driven motor, when one expander is expanding, another is put into the expander lubricant container. In this way, our expanders will have ever more long operation life.
