Liquid Vapour Regenerative Heat Exchanger. The refrigerant vapours coming out of the evaporator are superheated by 5°c and then pass through the regenerative heat exchanger to cool the liquid refrigerant coming from the condenser. If the total energy in the source at 50°c is 5 mw find the rate of energy delivered at the high temperature.

In this heat exchanger the fluid flow in an alternative way through the same flow passages and the heat transfer is intermittent. Air preheaters used in coke manufacturing and glass melting plants. In heat exchangers, there are usually no external heat and work interactions.

The thermal efficiency of the rankine cycle can be increased by. The remainder q2 goes into the heat pump that delivers a q3 at 150°c. The static type has no moving parts and consists of a porous mass like balls, pebbles, powders etc.
Regenerative Heat Exchangers May Be Either Static Type Or Dynamic Type.
A heat exchanger is a device that allows heat from a fluid (a liquid or a gas) to pass to a second fluid (another liquid or gas) with the two fluids at different temperatures and in thermal contact. A tube bundle of the heat exchanger contains 111 tubes, the diameter of one tube is 25×2.5 mm. The storage type heat exchanger is also known as the regenerative heat exchanger.
In Heat Exchangers, There Are Usually No External Heat And Work Interactions.
The actual time that hot gas takes to flow through a cold regenerator matrix is called the hot period or hot blow, and the time that cold gas flows through the hot regenerator matrix is called the cold period or cold blow. 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. The refrigerant vapours coming out of the evaporator are superheated by 5°c and then pass through the regenerative heat exchanger to cool the liquid refrigerant coming from the condenser.
3.Both The Condenser And Evaporator Are Heat Exchangers With Refrigerant As A Common Medium.
Such types of heat exchangers are used predominantly in air conditioning, humidification, industrial hot water heating, water cooling and condensing plants. Liquid vapour regenerative heat exchanger liquid vapour regenerative heat exchanger combines superheating of vapour with liquid sub cooling. In this heat exchanger the fluid flow in an alternative way through the same flow passages and the heat transfer is intermittent.
Air Preheaters Used In Coke Manufacturing And Glass Melting Plants.
To accomplish this the hot fluid is brought into contact with the heat storage medium, then the fluid is displaced with the cold fluid, which absorbs the heat. Pressure drop and heat transfer in connecting pipe lines Rankine cycle) regeneration means to take some part of heat from the expanding steam in the turbine to decrease the overall heat supplied in the process.
