Two AES exchangers in series have trouble heating up a process stream from 50ᵒC to 90ᵒC, and cooling down a hot stream with the same flow rate from 110ᵒC to 70ᵒC. Luckily, there is an abandoned AES exchanger available that has four times the surface of the two existing exchangers, and even better, it has the right material and sufficiently high design P & T, and would fit on the plot space occupied by the existing exchangers. Is replacement a good idea? Please provide all necessary formulas or principles.

Concept explainers

Heat Exchangers

Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.

Heat Exchanger

The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.

4. The following heat exchanger uses 10 kg/s of hot air to heat and boil liquid water into saturated steam at 500 kPa. (a) Find the steam flow (kg/s) (b) Determine whether the process is allowed by the second law (Answer: It is not!) (c) On the surface, the process looks OK as Tair>Twater at both the inlet and outlet. You should be able to see the problem if you sketch the air and the water temperature profiles as you move left to right through the exchanger. (Hints: The air will be essentially a straight line, while the water will not. For the water, think about what happens when it is changing phase.) This is called a pinch point violation, and it is a very important design consideration in advanced combined cycle systems and in nuclear power plants.

1. A heat exchanger is located on the roof of a warehouse to heat the air in winter. It is a coil-shaped pipe into which water vapor enters at 0.1 MPa and 300 °C and leaves with a quality of 30%. The warehouse has the following dimensions: 80m x 160m x 10m. The air must be heated from 5°C to 22°C. a. What must be the mass flow rate of the water to heat the air in less than half an hour? b. We want to cool the steam from the exchanger outlet and bring it up to 50 °C. For this, a mixing chamber with water at 20 °C is used, what will be the proportion of the steam mixture? c. The exchanger is damaged and only liquid water can be used at the same pressure (inlet T. 1 °C below saturation and outlet T. at 30°C). How long does it take to heat the air with the same flow of water?

Project 5: Automobile radiator, condenser, evaporator, air preheater, and cooling tower are common types of direct heat exchangers that also called recuperators. Recuperators may have different types based on the flow arrangement of the hot and cold fluid. Your role in a company that manufactures recuperators heat exchanger is to design a counter-flow recuperator (see Figure.6) that is used in heating, ventilation, and air conditioning (HVAC). Section.1: − Exhaust pipe is 88 ?? diameter. − Exhaust gas enters at 500??. − Water jacket is used and enters at 8??. − The surface heat coefficient of water and gas are ℎ????? = 300 ?/(?2.?) and ℎ??? = 1500 ?/(?2.?) , respectively. − Assume conduction transfer through wall is negligible. − The gas heat specific capacity is ?? is 1130 ?/(??.?). − The water heat specific capacity is ?? is 4190 ?/(??.?). − The flow rate of gas and water are 320 and 1500 ??/h, respectively. − The gas must be cooled to 100??.
