Plate heat exchanger company: How to assess the design performance of plate heat exchangers?
2021-05-27
Plate heat exchangers are widely used in our lives, mainly in factories, homes, and office areas. In fact, there are certain differences in the design performance of different plate heat exchangers. Therefore, how should one assess the design performance of a heat exchanger when purchasing one? Today, a plate heat exchanger company will explain this to everyone.
Plate Heat ExchangerWidely used in our lives, mainly for factories, houses, and office areas. In fact, there are certain differences in the design performance of different plate heat exchangers, so how should we judge the design performance of heat exchangers when purchasing them? Today, the plate heat exchanger company will explain this to everyone.
1. Calculate the heat exchange amount of copper pipes and aluminum foils to see if the material quantity is reasonable;
2. Calculate the ratio of the length of the effective heat exchange main pipe of the condenser and evaporator to the expansion area to see if the heat exchange capacity inside and outside is reasonably matched;
3. Analyze the suction and discharge pressure of the plate heat exchanger system. Different energy efficiency levels require different suction and discharge pressures. The higher the energy efficiency level, the lower the power consumption of the compressor, the smaller the pressure difference between the system's suction and discharge pressures, and the smaller the pressure loss of the system;
4. Check and analyze the temperature of the pipes entering and leaving the heat exchanger. The temperatures entering and exiting the plate heat exchanger can indirectly reflect the evaporation and condensation pressures, especially the temperature at the outlet of the heat exchanger, which directly reflects the subcooling of the condenser and the superheating of the evaporator, and directly reflects the heat exchange effect of the heat exchanger. If the return air temperature of the plate heat exchanger is too low, it is easy to cause frosting or even icing on the surface of the heat exchanger, which will lead to a vicious cycle in the system. If the outlet temperature of the condensing heat exchanger is too high, it will lead to subcooling and performance reduction.
5. Check whether the temperature distribution on the windward side of the product is uniform. A uniform temperature distribution indicates that the multi-channel distribution state is good, the heat exchange efficiency of each channel is basically the same, and the temperature difference inside and outside the entire windward side pipe is relatively consistent, which is beneficial to improve the overall efficiency of the plate heat exchanger. If the temperature distribution is uneven, it means that the multi-channel distribution state is poor, the heat exchange efficiency of certain pipes is poor, and they cannot fully exert their function. At the same time, it will affect the subcooling and superheating, and affect the overall heat exchange effect of the system.
The above isPlate Heat Exchanger Companythe judgment of design performance, hoping to be helpful to everyone. The design performance of the plate heat exchanger will directly affect our usage effect and our heating. Therefore, when we purchase water-to-water plate heat exchangers, we should not only consider the Price but also consider their lifespan and design performance.
