1. The temperature drop of the heat medium of the volume heat exchanger is large. During the steam-water heat exchange, the outlet temperature of the condensed water is about 50 ° C. Drainers need to be set up and down the return pipe, which facilitates the use and maintenance. During water-water heat exchange, the heat temperature drop is 2 to 2.5 times that of the same type heat exchanger, 120 The high-temperature hot water at ~ 150 ℃ can be reduced to 70 ~ 75 ℃ after heat exchange.
2. The volumetric heat exchanger has good heat exchange effect, good heat dissipation effect, small heat loss and energy saving. At the same time, when steam is used as the heat medium, about 15% of the heat of condensed water can be recovered.
3. The cold water area is small and the volume utilization rate is high.
4. It maintains the advantages of large-capacity heat exchanger with large water storage, low head loss, safe and stable water supply, and convenient cleaning.
