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..a. exhaust air ...b.compressor ..c.system blower..d. attic
Homework Answers
a. exhaust air.
Note-An HRV is a controlled ventilation system that reduces high humidity, pollutants and odours by replacing stale air with fresh warm air. Exhaust air is not only stale and damp, but warm. It is this warmth that is used to pre-heat fresh air as it enters your home..

Fats are a more efficient way to store biochemical energy than carbohydrates. Which of the following are true? Group of answer choices Fats can produce more energy per gram than carbohydrates. [ Choose ]FalseTrue It is easier to extract energy from fats than carbohydrates. [ Choose ]FalseTrue Fats are hydrophobic, so can be stored without water, meaning they take up less space. [ Choose ]FalseTrue Fats are less reduced than carbohydrates.

For saving energy, bicycling and walking are far more efficient means of trans- port than is travel by car. For example, when riding at 16 km/h, a cyclist uses food energy at a rate of about 1670 kJ/h above what he would use if merely sitting still. Walking at 5 km/h requires about 940 kJ/h. It is interesting to compare these values with the energy consumption required for travel by car. Petrol yields about 3.4x10'J per litre. The Volkswagen Golf...
In this problem you will estimate the heat lost by a typical house, assuming that the temperature inside is T(in) = 20 degrees celcius and the temperature outside is T(out) = 0 degrees celcius
In this problem you will estimate the heat lost by a typical house, assuming that the temperature inside is T(in) = 20 degrees celcius and the temperature outside is T(out) = 0 degrees celcius. The walls have fiberglass insulation, which dominates the heat conduction properties of the wall So we can consider the wall to have a thermal conductivity of k(wall) = 0.048 W/m/K . We will take the thickness of the walls and ceiling to be L(wall) = 12...

Thermal Storage Solar heating of a house is much more efficient if there is a way to store the thermal energy collected during the day to warm the house at night. Suppose one solar-heated home utilizes a concrete slab of area 14 m2 and 22 cm thick. Part A: If the density of concrete is 2400 kg/m3, what is the mass of the slab? Part B: The slab is exposed to sunlight and absorbs energy at a rate of 1.1...
