Plate heat exchangers are widely used in our daily lives, mainly in factories, houses, and office areas. In fact, there are certain differences in the design performance of different water water plate heat exchangers. Therefore, how to judge the design performance of heat exchangers when purchasing them? Today, the water water plate heat exchanger manufacturer will explain to you.

1. Calculate the heat exchange between the copper tube and aluminum foil to check whether the material amount is reasonable;

2. Calculate the ratio of the length of the effective heat exchange main pipes in the condenser and evaporator to the expansion area to check whether the indoor and outdoor heat exchange capacities are reasonably matched;

3. Analyze the intake and exhaust pressures of the system designed by the Shui-Shui plate heat exchanger manufacturer. Different energy efficiency levels require different intake and exhaust pressures. The higher the energy efficiency rating, the lower the compressor's power consumption, the smaller the pressure difference between the system's intake and discharge pressures, and the less pressure loss in the system;

4. Check and analyze the temperature of the pipes entering and leaving the heat exchanger. The temperature of the inlet and outlet water plate heat exchangers can indirectly reflect the evaporation and condensation pressures, especially the temperature of the outlet heat exchanger, which directly reflects the subcooling degree of the condenser and the superheat of the evaporator, and also directly reflects the heat exchange efficiency of the heat exchanger. If the return air temperature of the Shui-Shui plate heat exchanger from the manufacturer is too low, frost or even freezing can easily form on the surface of the heat exchanger, leading to a vicious cycle in the system. If the outlet temperature of the condensing heat exchanger is too high, it will lead to undercooling and reduced performance.

5. Check whether the temperature distribution on the upwind side of the Shui-Shui plate heat exchanger product is uniform. Uniform temperature distribution indicates good multi-channel distribution, with basically the same heat exchange efficiency across all channels. The temperature difference inside and outside the windward side tube is relatively consistent, which helps improve the overall efficiency of the water-water plate heat exchanger. If the temperature distribution is uneven, it means the multi-channel distribution is poor, and some pipes have poor heat exchange efficiency and cannot be fully utilized. At the same time, it affects the degree of supercooling and overheating, as well as the overall heat exchange efficiency of the system.

The above is the manufacturer's assessment of design performance from the Shui-Shui plate heat exchanger manufacturer. We hope it is helpful to everyone. The design performance of the Shui-Shui plate heat exchanger will directly affect our usage performance and our heating performance. Therefore, when purchasing a Shui Shui plate heat exchanger, we should consider not only the price but also its service life and design performance.
