Plate heat exchanger consists of thin, rectangular, pressed sheet metal plates that are sandwiched between full peripheral gaskets and clamped together in a frame. The frame has a fixed end-cover plate, fitted with the connecting ports, which is bolted together with a movable cover plate to hold the embossed plates in between; the top and bottom carrying bars allow proper alignment of the plate stacks. When compared with the well-established shell and tube heat exchangers, the plate heat exchanger shows a lot of advantages like high NTU values, compactness, low cost, multi duties and reduced fouling etc. Plate heat exchangers are often used to transfer heating or cooling water which is produced in the energy production( district heating or district cooling) facilities to residential areas and industrial parks. The district cooling systems of Middle East are the biggest market of plate heat exchanger, but the technical specifications for cooling system are different from the domestic one. To achieve its specifications, the new plate heat exchanger was developed, and its thermal performance results are introduced in this paper.
