Abstract: Provided herein are a heat exchange apparatus intended to achieve compatibility between installation flexibility and durability and a method of manufacturing the heat exchange apparatus. The heat exchange apparatus is a heat exchange apparatus that exchanges heat between a heat storage material and a fluid. The heat exchange apparatus includes a first heat storage module and a second heat storage module, each having the heat storage material and a box-like shape, and a housing containing the first heat storage module and the second heat storage module. The first heat storage module is disposed in the same orientation as that of the second heat storage module.

Abstract: An air-conditioning apparatus includes a housing, an evaporator, a condenser, and a water sprinkler for sprinkling condensed water to the condenser, the condensed water having been generated at the evaporator. The condenser includes a first header and a second header arranged parallel to each other, a first heat transfer tube and a second heat transfer tube that are arranged parallel to each other and are arranged between the first header and the second header, and a fin disposed between the first heat transfer tube and the second heat transfer tube.

Abstract: A plate heat exchanger causes heat exchange to be performed using a plurality of heat transfer plates stacked. Each of the heat transfer plates includes a plate body, a first-medium inlet, a first-medium outlet, a second-medium inlet, a second-medium outlet, and a projection that provides a passage. At least one of the first-medium inlet and the first-medium outlet is located at one of two corners at one end of the plate body which the projection contacts. At least one of the second-medium inlet and the second-medium outlet is located at one of two corners at the other end of the plate body from which the projection is separated.
