Outline lighting area definition and calculation method The maximum effective area of sunlight projected to the collector.
Heat capacity per unit area of a certain amount of solar radiation, the water temperature within the hot water storage tank is not less than the specified value, the unit outline lighting area of the hot water storage tank heat.
Average heat loss factor
In the absence of solar radiation conditions for a period of time, unit time, unit water volume solar water heater engineering system storage water temperature and the temperature difference between the unit temperature difference between the average heat loss.
  Antifreeze system uses antifreeze as a heat transfer medium to prevent frost damage indirect solar collector system.
  Solar Warranty Solar water heater engineering system by the solar heat supply system of the total heat load ratio.
  The system cost-effective ratio of solar hot water system investment and system in the normal life of the total energy saving ratio (yuan / kw · h), said the use of solar energy per kilowatt-hour conventional energy savings in the cost of investment.
