Abstract:
A fluid circuit arrangement, comprising: a first fluid circuit, a second fluid circuit, an interconnecting means for connecting the first circuit and the second circuit, the first circuit and the second circuit having a first fluid for circulation therein between the first and second circuits, the first circuit comprising a first heat exchange means for exchanging heat between the first circuit and its surroundings, the second circuit comprising a cooling means for controlled cooling of the first fluid and a second heat exchange means for exchanging heat between the second circuit and a second fluid, the second circuit also comprising an actuatable valve device and a temperature responsive control means for actuating the valve device and for controlling a flow of the first fluid through the cooling means to cool the first fluid flowing through the cooling means, and a heating means in at least one of the first and second circuits for heating the first fluid to maintain the temperature of the first fluid at a predetermined temperature, the control means being responsive to a temperature of the second fluid passing through the second heat exchange means.
