A Refrigeration cycle
i) Describe how this cycle is operated in heat pump mode
ii) Draw the heat pump refrigeration cycle in a Pv diagram
iii) Calculate the COP (coefficient of performance) as a function of only Qh and Ql.
iv) If the temperature inside your house remains constant, but the outdoor temperature gets colder, how does that impact the COP?
