Abstract:
1. An aircraft galley refrigeration system comprising: a first galley including a first galley inlet and a first galley outlet; a first chiller including a first chiller inlet and a first chiller outlet, the first chiller inlet being in fluid communication with the first galley outlet; a second galley including a second galley inlet and a second galley outlet; a second chiller including a second chiller inlet and a second chiller outlet, the second chiller inlet being in fluid communication with the second galley outlet; and a multi-circuit fluid heat exchanger including a first exchanger inlet, a first exchanger outlet, a second exchanger inlet, a second exchanger outlet, a first circuit defined between the first exchanger inlet and the first exchanger outlet, a second circuit defined between the second exchanger inlet and the second exchanger outlet, a first fluid circulating through the first circuit, and a second fluid circulating through the second circuit, the first and second circuits being distinct and separated such that the first and second circuits are not in fluid communication with each other and such that the first and second fluids do not mix with each other, the first exchanger inlet being in fluid communication with the first chiller outlet, the second exchanger inlet being in fluid communication with the second chiller outlet, the first exchanger outlet being in fluid communication with the first galley inlet, and the second exchanger outlet being in fluid communication with the second galley inlet, such that the first fluid circulates through the first circuit, the first galley and the first chiller to form a first closed loop, and the second fluid circulates through the second circuit, the second galley and the second chiller to form a second closed loop, wherein the first and second circuits are first and second channels haying a common wall separating the first and second fluids, the first and second circuits being in thermal communication with each other for distributing heat between the first and second fluids.
