First, the volume of heat exchanger type RV03 series by volume 1.5m3 to 15m3 with a total of 6 sizes, corresponding to each of the specifications according to tube type heat medium and high temperature steam kind of softened water type, and each model at a conversion different thermal area was divided A, B, C three models, suitable for hot water production when different selection. RV04 Series by volume 1.5m3 to 15m3 with a total of 23 kinds of specifications, but also steam and hot water type heat medium can be two kinds of heating, each model there are A, B, C, D four kinds of heat transfer area, adapted to different amount of hot water needs. Second, the application of occasions in this series of heat exchangers are widely used in general industrial and civil water supply, such as hotels, nursing homes, high-rise buildings, stadiums, residential areas, schools and other industrial water units, compared to other similar heat exchanger has small footprint, energy saving, and reliable operation. Third, the material body according to user requirements, choice of stainless steel type (1Cr18Ni9Ti, or import plate SUS304), carbon steel lined copper type, U-tube heat exchanger material: Stainless Steel Pipe (1Cr18Ni9Ti), carbon steel pipe (20 #), purple Copper (T2). Carbon steel casing corrosion external coating mixed paint. Fourth, the design instructions: heated water outlet temperature tolerant at 75 ℃, the actual use, the delay scale, the heating water outlet temperature should be controlled at between 50-60 ℃. Five, the heat exchanger No. Description: RV Series volume heat exchanger performance characteristics: the use of small diameter beam tubes, heat medium two heat exchangers. Additional diversion tank, baffle, design optimization, greatly improve the heat transfer coefficient; using multi-beam tubes of new processes, thermal coal utilization, energy saving; heating medium temperature drop is large, the normal use or not to set traps, Condensate water temperature of about 55 ℃; entire bundle can be withdrawn from the front, maintenance is very convenient; cold area is small, the volume utilization rate of 90%; overall performance is far superior to similar standard cans, efficiency, energy saving; supporting imported automatic temperature control raft, automatic control diffuse water comfort, energy saving, replacing someone on duty operation.
