The Main Performance Index of Plate Heat Exchanger for Urban Waste Heat

图片
The main performance indicators of the plate heat exchanger for urban waste heat: air heat source set area, the volume reduced about 25%. Sewage water heat source set area, the volume reduction rate is about 40%, pressure capacity increased about 20%.  www.hfm-phe.com Characteristics: 1. Small and efficient The process of heat transfer is carried out in the 0.5mm sheet with a high heat transfer efficiency. After channeling the heat transfer efficiency is 90% or more. 2. Difficult to block The exhaust flow the plate up and down through the laminar flow, at the same time, due to the gas flow into the formation of 60 degrees angle, the dust will not block. 3. Easy to clean Although the heat exchanger should not be easily blocked by dust, if used in large number of dust places, it should be set by the automatic cleaning device; which can be cleaned in the appropriate interval at any time. Generally it need to be cleaned by 60 degrees of hot water, and sometimes must be
