The performance of two typical types of solar hot water heating system was tested in Seoul. Types of systems studied are single-tank indirected external heat exchanger system and single-tank internal heat exchanger system. Comparing to experimental results, a transient system simulation program was made to analyze the performance of the selected system.
The climate data, Standard Weather Year for Seoul, required for the simulation was provided. Computer simulations were used to estimate the effect of significant parameters upon system performance. The followings are obtained.
1. In the domestic solar water heating system, the value 20-40㎏/㎡h for flow rate through the collector is much better than the recommended value 72㎏/㎡h in the solar heating system.
2. The effectiveness of collector heat exchanger and storage tank size are found to have only a small effect upon system performance.
3. The hot water draw pattern has a significant effect on system performance. A higher system efficiency achieved when draw-off occurred around noon than when it occurred around, early morning.
Using the above results, the reference solar hot water system which provides 300ℓ of hot water per day, was selected as a guide for designer. And simplified graphical method was developed based on the modified f-chart method to determine required collector area. When the system design parameters of the proposed system differs from the reference system, required collector area can be calculated from area adjustment factors.
