Low Cost Solar Water and Space Heating Systems

چکیده
Market penetration studies indicate that in the absence of tax credits, large reductions in the costs of active solar water/space heating systems will be necessary. A number of potential means for equipment and labor cost reductions are presented. The use of drainback systems with polybutylene pipe and a variety of low-cost collector concepts is discussed. The pros and cons of the various drainback configurations are described in terms of performance and potential for cost reduction. The use of integrated collector/storage (ICS) systems was also studied.

متن کاملThermodynamic analysis of a novel solar water heating system during low sun radiation in Iran
This paper reports a plenary thermodynamic model of a novel solar system for water heating in buildings. Energy and exergy analyses are used to characterize the exergy destruction rate in any component and calculate system overall efficiency. The system consists of a solar evaporator, a heat exchanger to produce hot water, and an auxiliary pump. A computer simulation program using EES software ...
متن کاملInvestigating the effect of hot water consumption profile on the performance of solar water heating systems
In this paper, a forced circulation solar water heater system is simulated for different hot water consumption profiles using flat plate collectors as well as evacuated tube collectors. The profiles studied are the actual samples of hot water consumption profiles for different commercial centers and institutions. Dynamic simulation outputs of system thermal performance are used as economic anal...
متن کاملPerformance Study of a Solar Integrated Central Heating System of a Residential Building Using Trnsys- an Hourly Simulation Model (RESEARCH NOTE)
In this investigation, the performance of an existing heating system of a residential building incorporated with an array of solar thermal collectors was studied. For this purpose, transient systems simulation program model was assembled to estimate the hour-by-hour performance of the existing and the system equipped with the solar thermal collectors in terms of the provided space air condition...
متن کاملComparative performance assessment of flat plate and evacuated tube collectors for domestic water heating systems in Kerman, Iran
This study represents a year-round energy performance of two solar water heating (SWH) systems with a 4m2 flat plate collector (FPC) and an evacuated tube collector (ETC) operating under the same weather conditions. The energy performance of the two considered systems was compared on a monthly and yearly basis. The obtained results showed that for an annual total solar insolation of ...
