A heat recovery ventilator is more energy efficient than a balanced ventilation system consisting of an exhaust blower and a supply air blower because it recovers energy from the exhaust air.
Added by M-Nica S.
Step 1
This reduces the energy needed to heat or cool the incoming air, making the system more energy efficient. A balanced ventilation system with an exhaust blower and a supply air blower simply moves air in and out of the building without recovering any energy. This Show more…

Air enters a gas turbine with two stages of compression and two stages of expansion at $100 \mathrm{kPa}$ and $17^{\circ} \mathrm{C}$. This system uses a regenerator as well as reheating and intercooling. The pressure ratio across each compressor is $4 ; 300 \mathrm{kJ} / \mathrm{kg}$ of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by $20^{\circ} \mathrm{C}$. Determine this system's thermal efficiency. Assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.

A cool and heating system uses two ducts, one that carries hot air and one that carries cold air. The air flow from the ducts meet in the mixing chamber. The device that actually sets the mounts of air leaving each duct is the? A) Damper motor B) Fan coil value C) Unit ventilator D) Mixing contactor
