a. COP of a heat pump is

(a) always less than 1 (COP 1)

(b) always equals to 1 (COP = 1)

(c) always less than infinity (COP ∞)

(d) always equals to infinity (COP = ∞)

b. Choose the correct relation between COP of heat pump and COP of refrigerator?

(a) (COP )HP = 1 − (COP )ref

(b) (COP )HP = 1 + (COP )ref

(c) (COP )HP = (COP )ref

(d) none of the above
