ABSTRACT:
A multi-mode water heating system wherein a capacity control mechanism is provide so that no additional heat source is required and via use of capacity control, either solar radiation energy or ambient air energy is selectively utilized dependent on the availability of sunshine. A system configuration is so arranged as to maximize the system seasonal coefficient of performance by a refrigeration cycle optimization which adjusts both a pump/compressor speed and pressure regulating valve opening.
