Chapter 6 part 2 Passive Solar Space Heating Active Solar Space Heating Thermal Energy Storage Summary

Energy in the News

Direct Gain Space Heating Why is thermal mass important? (Thermal time constant of building?) Why did medieval lords live in stone castles? Are these best for dry or wet climates?

Performance of a Passive Solar Building What is the range of interior building temperatures? Range Of outside temperatures? No auxiliary heat is used in this building, Located in Concord, New Hampshire.

Trombe Wall Heat stored within Concrete wall Vents closed at Night. Wall radiates heat.

Solar Greenhouse (Indirect Gain) Can grow plants In greenhouse. Reduces air Dryness in winter Why?

Active Solar Hot Water System What additional features are required in an active Solar system compared to a conventional water heating System? (European vs American hot water heating systems)

Hot Air Flat Plate System Thermal mass provided By rock bin. Solar collector uses air, not water. Hot air moved By fan to rock bin or directly To rooms of house. Water preheated in rock bin. Good for humid climate. Not as efficient as water Based solar system. Why?

Optimum Solar Collector Angle Why does the Optimum collector Angle vary as a function Of the season?

How Big Should a Solar Collector Be? Q = I * epsilon * A Where Q is the heat I is the average solar insolation at the site Epsilon is the efficiency of the solar collector A is the surface area of the solar collector

Thermal Energy Storage Q = m*c* delta T Where Q is heat, m is mass, c is the specific heat Of the substance and delta T is the change in temperature. What is better for thermal energy storage, a substance With a high specific heat or a substance with a low specific Heat? Why? How does mass affect the thermal energy storage of a System?

Heat Capacity Heat capacity = specific heat * density

Storing Energy in Phase Changes Why are phase changes a very effective method of energy storage? (think of changing water to steam)

Components of Solar Heating Systems Solar Collector Thermal Energy Storage Distribution System Active Systems: have pumps or fans
