Answer:
$187.61
Step-by-step explanation:
Data provided:
Temperature of the heat exchanger, Tc = 2° C = 273 + 2 = 275 K
Temperature of the base board radiators , Th=47° C = 273 + 47 = 320 K
Cost of heating the house = $1000
Coefficient of performance of the heat pump = 75% = 0.75
Now,
Actual performance = 75% of performance of heat pump
or
Actual performance = 0.75 ×
or
Actual performance = 0.75 ×
or
Actual performance = 0.75 ×
or
Actual performance = 5.33
Therefore, the cost =
or
cost = $187.61
