Solar Thermal System Quiz

What is the purpose of the solar collector in a solar thermal system?

• To pump water through the system

• To collect heat by absorbing heat radiation from the sun

• To store hot water

• To control the temperature of the system

Which of the following are types of thermal collectors mentioned in the handout?

• Concentrated solar power collectors

• Flat plate collectors

• Photovoltaic cell collectors

• Evacuated tube collectors

What triggers the Differential Temperature Controller (DTC) to activate the pump in a solar thermal system?

• When the solar collector is too hot

• When there is a demand for cold water

• When there is enough solar energy and a demand for hot water

• When the hot water storage cylinder is empty

What is the role of the circulating pump in a solar thermal system?

• To generate heat within the system

• To control the temperature of the hot water cylinder

• To circulate the heat transfer fluid around the system

• To fill the solar collector with water

What substance is commonly used as the heat transfer fluid in a solar thermal system, according to the handout?

• Water

• Glycol

• Freon

• Mineral oil

What is the purpose of a hot water storage cylinder in a plumbing system?

• To store cold water before it is heated

• To enable the heat transfer from the system fluid into the stored water

• To generate heat within the system fluid

• To pump water into the heating system

How are hot water storage cylinders typically coiled?

• Double-coiled

• Triple-coiled

• Multi-coiled

What is the lower coil (primary) of a hot water storage cylinder connected to?

• The electrical grid

• An auxiliary heat source (boiler)

• The solar system

• The main water supply

What is the higher coil of a hot water storage cylinder connected to?

• The solar system

• The main water supply

• An auxiliary heat source (boiler)

• The electrical grid
