Investigation of Solar Heated Absorption-Refrigeration Process for the Air Conditioning of Buildings.

摘要

The consumption of primary energy in buildings can be reduced by means of the solar heated absorption refrigerator (AKM). Related to local climatic conditions, a strategy to solve the problem was developed, by which the operating behavior of the individual system components and of the whole process can be examined, depending on the existing system parameters. Processes for calculating the part processes relevant to the system were derived. In order to describe the operating conditions of the AKM, algorithms were developed for determining the part load behaviour and cyclic method of operation. Computerized process simulation showed that with a suitable choice of size of collector and content of the store, a suitably designed solar heated AKM could provide the required amount of refrigeration in monovalent operation. Optimum operating characteristics are obtained by a solar collector system inclined at an angle of about 30 exp 0 and orientated towards the south. Taking an average for the months of May to September, about 15% of incoming solar energy can be used for air conditioning purposes. (ERA citation 10:008504)
