Question

You need to complete solution of selected project.
Then you will need to suggest an alternative
with your stage 1 solution. That alternative can be completely different than given system in the project, or it could be alterations of some parts. You should explain why you are making the changes and what improvements you expect. Your final solution may show surprises. The Alternative need not be better, or best or perfect at the end. Do not try to optimize it. We are looking how you analyze the given energy systems and compare them properly not if those suggestions or alternatives are best possible solutions. Though your thought process in suggesting alternative does count.

Your solution should include 
a. Energy input requirements as well as required components (you need to make it work) 
Ans. 
1. Energy required:
2. Component: -
	1. Heating equipment – Heater CO bases
		a. Evaporator.
		b. Expansion Value.
		c. Condenser.
		d. Compressor.
	
b. Identify the irreversibility’s (entropy production) in the processes or in different components.
Ans. Heat cycle form the reservoir Qc. This requires work input W, which converts to heat transfer. Therefore, heat transfer = Qh = Qc+W , where, Qh,Qc and W are positive, with the direction indicated.
Figure 1. Heat pump’s heat engines operated backward. 
(a) The directions of W, Qh, and Qc are opposite what they would be in a heat engine. 
(b) Consider the path ADCBA. The area inside the loop is negative, so negative work input. 
Heat Pump:
The advantage of using a heat pump to keep your water warm, rather than just burning fuel, is that a heat pump supplies Qh = Qc + W. Heat transfer is from the outside air, even at a temperature below freezing, to the indoor space. You only pay for W, and you get an additional heat transfer of Qc from the outside at no cost. The disadvantage is that the work input which required by the second law of thermodynamics. The basic components of a heat pump in its heating mode are shown in Figure 2. heat transfer Qc occurs to the working fluid from the cold outdoor air.
A simple heat pump has four basic components: 
(1) condenser, 
(2) expansion valve, 
(3) evaporator, and 
(4) compressor. 
In the heating mode, heat transfer Qc occurs to the working fluid in the evaporator (3) from the colder outdoor air. The electrically driven compressor (4) increases the temperature and pressure of the liquid and forces it into the condenser coils (1) inside the heated space. Because the temperature of the liquid is higher than the temperature in the room, heat transfer from the gas to the room occurs as the gas condenses to a liquid. The working fluid is then cooled as it flows back through an expansion valve (2) to the outdoor evaporator coils.
c. Performance on the first law (energy basis). You can use EUF, thermal efficiency, coefficient of performances as it fits the application.
