초록
A new plate heat exchanger for water-refrigeration systems such as chillers has been developed. Before forming, two stainless steel plates are placed on each other and connected by tig welding. To outline of the plate did the seam welding, in order to form the flow pass on the plate inside the spot welding used. After the plates have been welded, the plates are hydraulically inflated using pressure by water or nitrogen. The plate is made of an SUS plate of 1m×2m in length and 1.2㎜ in thickness and are fixed in the top of the water tank. As a result of these, it is concluded that the plate exhibits good cooling performance and the average cooling capacity is approximately 2.9RT/plate and the average coefficient of performance (COP) of chiller system is 3.16.
