A heat exchanger 14 comprises a first heat exchanger 32 in a first fluid circuit (12, fig 1), a second heat exchanger 46 in a second fluid circuit (16). The first and second heat exchangers define a heat exchanger package 54 embedded in an accumulator medium 52 in a container (176, fig 4c) and are arranged in cross-counterflow. The first heat exchanger may be an evaporator in a refrigeration circuit and the second heat exchanger may be a water cooler in a water circuit. The accumulator medium may be a heat storage paraffin mixture from crude oil. The heat exchangers may be a plurality of copper pipes 64, 68, 72, 76, 80, 84, 88, 92 with copper fins 84 spaced along the length of the package. An air conditioning system containing the heat exchanger is also claimed and provides cooling of a diver pressure chamber and maintains its temperature during power failure. |
