NANOFLUIDS: LOOKING FOR MORE EFFICIENCY IN SOLAR HEATING SYSTEMS

Sizing of a Packed Bed Storage for Solar Air Heating Systems (TECHNICAL NOTE)

Packed bed units generally, represent the most suitable storage units for air heating solar systems. In these systems the storage unit receives the heat from the collector during the collection period and discharges the heat to the building at the retrieval process. A method for sizing of packedbed storage in an air heating system is represented. The design is based on the K-S curves, which hav...

Sustainable Development for Solar Heating Systems in Taiwan

In response to the impact of the United Nations Framework Convention on Climate Change, developing and using renewable energy sources and technologies have become vital for managing energy supply and demand in Taiwan. The long-term subsidy programs (1986–1991, 2000–present) for solar water heaters (SWHs) launched by the Taiwanese government constitute the main driving force for market expansion...

Investigating 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...

Instrumentation Principles for Performance Measurement of Solar Heating Systems

An instrumentation design and implementation plan for monitoring the performance of solar heating systems and of their components is described. Specifically the selection of the data acquisition system and of the sensors, the procurement process and installation and calibration principles are discussed in detail. As a practical example, the cost and choice of measurement methods and instruments...
