A thermal system for a marine vessel, such a system installed in a marine vessel, a marine vessel comprising such a thermal system, a method of controlling a thermal system and a control device

Abstract

The invention relates to a thermal system for a marine vessel, comprising a hot liquid circuit (10), a pump system (11) for circulating hot liquid in the hot liquid circuit (10), a plurality of heat consumers (20) arranged in parallel in the hot liquid circuit (10) and in series with a respective pressure independent control valve (PICV) (30), and a control device (12) for controlling the pump system (11). A differential pressure sensor (13) is adapted to sense a differential pressure indicative of a differential pressure over a key pressure independent control valve (30.1a) of the pressure independent control valves, and a signal from the differential pressure sensor (13) is used by the control device (12) as a basis for controlling the pump system.
