Selection factors | Consider the content |
thermal load | The heat transfer required by the heat exchanger is calculated according to the heating area, building enclosure structure heat loss and other factors |
fluid media | The first side is the high temperature hot water provided by the central heating pipe network (with a small amount of corrosion inhibitor), and the second side is the heating circulation water |
Import and export temperature | The inlet and outlet temperatures of the primary and secondary fluids are determined according to the design of the heating system, which is used to calculate the logarithmic mean temperature difference (LMTD) |
rate of flow | The flow rate of primary and secondary fluids is calculated according to the heat load, fluid specific heat capacity and temperature difference between inlet and outlet |
Allow pressure drop | Considering the head of the heating system pump and the pipe network resistance, determine the allowable pressure drop of the heat exchanger |
material quality | Select appropriate heat exchanger material according to fluid medium properties |
Plate type | Select the appropriate corrugated plate type according to eat transfer efficiency and pressure drop requirements |
Size and connection method | Select the appropriate heat exchanger shape and connection diameter according to the installation space and the connection requirements with heating pipes |
Brand and quality | Choose well-known brands in the market to ensure product quality and after-sales service |
