What are the three main reasons for the unsatisfactory application effect of semi volumetric heat exchanger

- The structure of the semi volumetric heat exchanger is unreasonable: the semi volumetric heat exchanger must be assembled according to the actual application needs of users and project working conditions when it leaves the factory in accordance with the national requirements. In order to save costs, some manufacturers do not lead the team according to the national requirements., The heat exchanger can only achieve the effect of heat conversion and follow the law of energy conductivity. The heat released from the hot side is equal to the heat absorbed by the cold side. Generally, the heat from the heating system on the hot side is taken away by the cooling water on the cold side that does not meet the requirements. If the water volume and water temperature are not good, the temperature on the hot side will not drop, so no matter how big the heat exchanger is, the effect will be poor.
2. The semi volumetric heat exchanger does not conform to the production standard: the manufacturer of the heat exchanger shall carry out standard production and planning according to the national standard requirements and industrial standards, and shall deliver the heat exchanger to the user after passing the relevant inspection and pressure test before leaving the factory; Some small manufacturers do not follow the normal production procedures and circulation, and plan and make without permission, which will lead to unsatisfactory heat exchange effect.
3. The type selection of semi volumetric heat exchanger is not standard and the flow is not well considered: many users only provide the relevant heat exchange area or heat exchange when consulting the price or purchasing equipment, and only consider the heat exchange surface of the heat exchanger, regardless of the circulation medium, the nature of the circulation medium, the flow of the circulation medium, the composition of the circulation medium and the working pressure of the relevant circulation medium, As a result, the selection of half volume heat exchanger is large or small, so the heat exchange effect of half volume heat exchanger is not ideal.
