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.
