Which limitation arises when a heat pump’s supply temperature increases significantly on cold days?

💡 Explanation

A decreased coefficient of performance occurs because overcoming the greater temperature differential requires more energy to drive the heat pump cycle while delivering adequate heat; therefore, efficiency drops rather than performance improving under strain, due to thermodynamics.
