Heat exchanger - Wikipedia

A heat exchanger is a system used to transfer heat between two or more fluids.Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural

Apr 03, 2021 · A condenser separates the water vapor from the reaction products. This condenser is a simple pipe with outlets on the bottom to collect water; natural convection on the surface of the pipe is enough to carry out the necessary heat exchange. Electrolysis of the water recovers the hydrogen for reuse. NASA 2007.

Manual on hatchery production of seabass and gilthead

The double system prevents interruptions in heated water and air supply in case of failure of one boiler. Heating systems are usually based on fuel oil or natural gas burners. From the boiler room, two separate steel pipelines feed the heat exchangers for seawater heating and the air heaters.

Boiling water reactor - Wikipedia

A boiling water reactor (BWR) is a type of light water nuclear reactor used for the generation of electrical power. It is the second most common type of electricity-generating nuclear reactor after the pressurized water reactor (PWR), which is also a type of light water nuclear reactor. The main difference between a BWR and PWR is that in a BWR, the reactor core heats water, which turns to

Comparative Study of Refrigerations Systems for Ice Rinks

Option A5 shows a high heating COP at 21.5. Reciprocating compressors offer the potential of more heat recovery for hot water heating due to a high gas discharge temperature. Option C2 shows a high heating COP of 19.8. This system does not use circulating pumps for heat recovery and the only other expense is for auxiliary water heating.
