A heat pump with a COP of 3.2 is used to heat a perfectly sealed house (no air leaks). The entire mass within the house (air, furniture, etc.) is equivalent to 1200 kg of air. When running, the heat pump consumes electric power at a rate of 5 kW. The temperature of the house was 7°C when the heat pump was turned on. If heat transfer through the envelope of the house (walls, roof, etc.) is negligible, the length of time the heat pump must run to raise the temperature of the entire contents of the house to 22°C is (a) 13.5 min (b) 43.1 min (c) 138 min (d) 18.8 min (e) 808 min
You have three devices: a Carnot heat engine, a Carnot heat pump and a Carnot refrigerator. Use a cold reservoir temperature of -18C. Plot the heat engine Carnot efficiency, the COPrefrig, and the COPhp as a function of the hot reservoir temperature from 27C to 177C. Use temperature increments of 5K in your plot. Make sure and reference a previous slide 'how to make a plot' that gives you the key elements of making a graph (in your choice of software). Describe what you see. Also describe the illustrated relationship between COPhp and COPref.
An inventor comes to you saying he has invented a refrigerator that maintains a room at 20F while operating in a location at 80F with a coefficient of performance of 8.5, is this possible?

A refrigerator is to maintain eatables kept inside at 9°C. If room temperature is 36° C, calculate the coefficient of performance.
A heat pump supplies heat energy to a house in order to maintain its temperature at 20°C. Over a period of one month, the heat pump operates for 100 hours to transfer energy from outside to inside the house. There are two possible heat reservoirs where the heat pump can operate on.Scenario 1: The heat pump receives heat from the outside air at -5°C.Scenario 2: The heat pump receives heat from a lake having a water temperature of 8°C.Upon comparing the two heat reservoirs, the house would be able to save $17 with the lake rather than the outside air. Assuming that electricity costs $0.12/kW-h.a. What is the maximum COP of the heat pump if the outside air is used?b. What is the maximum COP of the heat pump, if the lake as source is used?c. How much heat is lost by the house?*Round off all answers to four decimal places*

Prove that if you had a heat engine whose efficiency was better than the ideal value (4.5), you could hook it up to an ordinary Carnot refrigerator to make a refrigerator that requires no work input.
Q/ Two Carnot refrigerators operate in series between two reservoirs maintained at 20°C and 200°C, respectively. The energy output by the first refrigerator is used as the heat energy input to the second refrigerator. If the COPS of the two refrigerators are the same, what should the intermediate temperature be?
