And Storage

Seasonal and annual performance data are available on only a limited number of the several thousand solar space heating systems now in operation. The emerging information indicates that most of the heat required in buildings can be supplied by solar energy delivered from flat-plate collectors and stored overnight in tanks of water and bins of rock pebbles. Numerous mechanical and operational problems, mainly in liquid collection and storage systems, demand attention. Annual costs of solar heating equipment and its installation usually exceed current values of energy savings, but fuel prices are expected to escalate at rates which often favour solar purchase today. Detailed performance data on several types of solar heating and cooling systems in buildings of identical design are presented, compared and interpreted. Maintenance and repair requirements are noted and contrasted, and forecasts of use in various applications are presented.

The Impact

Global climate change mitigation requires the fossil fuel consumption substantially reduced. Space heating is an energy-consuming sector. Despite the fact that the thermal efficiency of current space heating systems has achieved a value higher than 85%, corresponding to lower than 40kg c.e./GJ, there is still a big potential for energy conservation. In order to realize the full potential, investigations of heating systems should appeal to reversibility/exergy analysis made on total energy concept basis. This paper starts with an introduction of the concept “reversible mode of heating,” leading the readers think of space heating in terms of reversibility. Right after, a systematic reversibility analysis on a “mine to home” basis is conducted to reveal the impact of any irreversibility of all subsystems or devices involved in the total energy system of heating on the fuel/monetary specific consumption of unit end-use heat. The paper points out that although combined heat and power (CHP) and electrically driven heat pump are both of “reversible mode,” the former is far more favorable in terms of energy conservation. The recently ascent decentralized energy system provides the best circumstances for CHP implementation. The demand-side improvement is a topic of most importance but frequently neglected. This study reveals that, if properly engineered, this improvement together with adopting a direct type of heat grid might lower the fuel specific consumption of end-use heat of CHP to a level as low as 13–9kg c.e./GJ.
