AS 4234:1994 PDF Download

A detailed technique is provided by the AS 4234:1994 standard for calculating the annual performance of household solar and heat pump water heaters. To evaluate the annual load cycle task performance of these systems, the standard combines test findings for component performance with a mathematical model. The energy usage of the water heaters can be accurately estimated using this method over time.

A software disk containing a tool to assess the energy usage of the solar water heaters being tested is given to make it easier to implement this standard. This program probably streamlines the computation process, improving accuracy and efficiency.
