Performance analysis of solar space heating system

The paper deals with solar space heating for a school during winter. The system, which is an extension of Solar Vapour Absorption Cooling Project, consists of coupling the solar collector field, the air handling units and the thermal energy reservoir in a single circuit with one pump. The analysis of the system has been done to describe the temperature history of the hot water reservoir as a function of two non-dimensional parameters. These parameters, which are functions of environmental and air handling unit characteristics, dictate the net thermal energy inflow or outflow from the reservoir. The problem solution has been obtained in a generalized form and predicted results are shown in dimensional form for the basic data chosen from an actual on-going project.
