You will explore the full range of heat pump system configurations \u2014 from combinations with solar collectors and PV arrays to ground-source loops and ice storage \u2014 and learn how to model both heating and cooling operation, maximise PV self-consumption, and optimise the control strategy of cascades serving multiple buildings or consumer groups.<\/p>\n<h3><strong>Content:<\/strong><\/h3>\n<h4><strong>Part I <\/strong><strong>\u2014 <\/strong><strong>Heat pumps<\/strong> (Self-learning video)<\/h4>\n<ul>\n<li>Heat pump basics and
