Air Reversed Carnot Cycle
Reversed Carnot cycle is an ideal refrigeration cycle for constant temperature external
heat source and heat sinks. Figure 1 shows the schematic of a reversed Carnot
refrigeration system using air as the working fluid along with the cycle diagram on T-s
and P-v coordinates. As shown, the cycle consists of the following four processes:
Process 1-2: Reversible, adiabatic compression in a compressor
Process 2-3: Reversible, isothermal heat rejection in a compressor
Process 3-4: Reversible, adiabatic expansion in a turbine
Process 4-1: Reversible, isothermal heat absorption in a turbine
Figure 1 shows the flow diagram air reversed Carnot cycle, while figure 2 presents the
different process of the reversed Carnot cycle on the (T-S) diagram
heat source and heat sinks. Figure 1 shows the schematic of a reversed Carnot

How Mr Benjamin Lee service granted me a loan!!!
ردحذفHello everyone, I'm Lea Paige Matteo from Zurich Switzerland and want to use this medium to express gratitude to Mr Benjamin service for fulfilling his promise by granting me a loan, I was stuck in a financial situation and needed to refinance and pay my bills as well as start up a Business. I tried seeking for loans from various loan firms both private and corporate organizations but never succeeded and most banks declined my credit request. But as God would have it, I was introduced by a friend named Lisa Rice to this funding service and undergone the due process of obtaining a loan from the company, to my greatest surprise within 5 working days just like my friend Lisa, I was also granted a loan of $216,000.00 So my advice to everyone who desires a loan, "if you must contact any firm with reference to securing a loan online with low interest rate of 1.9% rate and better repayment plans/schedule, please contact this funding service. Besides, he doesn't know that I am doing this but due to the joy in me, I'm so happy and wish to let people know more about this great company who truly gives out loans, it is my prayer that GOD should bless them more as they put smiles on peoples faces. You can contact them via email on { 247officedept@gmail.com} or Text through Whatsapp +1-989 394 3740.
