A heat recovery ventilation system saves energy by:
A) Decreasing the size of the indoor air-conditioning system blower.
B) Exchanging heat between the supply and exhaust air streams.
C) Preheating the ventilation exhaust air with electric heat strips.
D) Preheating the ventilation supply air with electric heat strips.
Question 2
The terminal and wire resistance values are critical in electric furnaces because the large current draw from the strip heaters:
A) Causes electro radiation.
B) Increases if the overall circuit resistance increases.
C) Turns even small resistances into heat that accelerates oxidation.
D) Causes arcing to ground at connections with a high resistance.
