Operational modes of solar heating and cooling systems

Operational Modes of Solar Heating and Cooling Systems

This paper emphasizes factors associated with the subsystems that are required to extract heat from solar collectors, store this heat, and deliver it to the loads upon demand. While minimum use of auxiliary energy is the general objective, it must be sought with due regard to safety, convenience and cost. Subsystem alterations that improve energy efficiency typically come at added cost in terms...

Solar Heating and Cooling for Residential Applications

Design Considerations for Residential Solar Heating and Cooling Systems Utilizing Evacuated Tube Solar Collectors

As solar heating systems become a commercial reality, greater efforts are now being employed to incorporate solar cooling components in order to obtain a complete solar heating and cooling system, and thus take advantage of the cost-effectiveness of year-round use of the solar equipment. The solar heating and cooling system design presented in this paper incorporates design considerations which...

Review of passive solar heating and cooling technologies

Heating, ventilating, and air-conditioning (HVAC) are parts of the major energy consumption in a building. Conventional heating and cooling systems are having an impact on carbon dioxide emissions, as well as on security of energy supply. In this regard, one of the attempts taken by researchers is the development of solar heating and cooling technologies. The objective of this paper is to revie...

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...
