Abstract
A make-up tank is provided for two separate heat exchanger circuits operating at different temperatures, the tank having three compartments, a first compartment acting as a make-up tank for the first circuit, a third compartment as a make-up tank for the second circuit and a second or stagnant buffer compartment to separate the first and third compartments. A water level monitor and supply system is provided in one of the compartments only and the compartments are in restricted communication with each other.
Claims7
A liquid filled heat exchanger system comprising a first circuit including at least one first heat generator and at least one first heat remover, a second circuit including at least one second heat generator and at least one second heat remover, the two circuits operating, in use at two different average temperatures, a liquid make-up tank for both circuits, the tank having three zones, a first zone, a second buffer zone and a third zone, the first zone being in direct communication with the second zone for the passage of liquid therebetween, the third zone being in direct communication with the second zone for the passage of liquid therebetween, there being no direct communication between the first and the third zones except through the second zone, a liquid supply line and at least one liquid bleed return line for the first circuit, the lines being connected to the first zone, a liquid supply line and at least one liquid bleed return line for the second circuit, the lines being connected to the third zone.
