The technical components of heat exchange equipment are the main thermal application equipment installed and used in my country's modern heating technology system, and the actual level of heat exchange efficiency has a direct and profound impact on the overall development of my country's heating industry. Efficiency seriously affects the heating effect, so what are the reasons for the low heat transfer efficiency of plate heat exchangers in the heating industry? Let's briefly introduce them today.

One: Dirt and scale, the main network connected to the heating system on the high-temperature side is basically below 1% due to the low water loss of the system, and according to the characteristics of the supply industry, the equipment is in a non-working state during the non-heating period every year, and it is basically used during the shutdown period. Full water belt pressure protection, therefore, a large amount of medium is rarely replaced, resulting in an increase in the reproduction of microorganisms. Its adhesion is strong, and it is easy to be in the low flow position of the heat exchanger, thereby forming fouling, which further affects the heat transfer efficiency of the heat exchange equipment. Two: The plate heat exchanger leaks, and the heat exchanger is tightly sealed by the sealing tape. For the heat exchange equipment used in the heating industry, the rubber strips are often aging after a few years, resulting in equipment failure, and finally even The plates are permanently deformed and the heat exchanger is difficult to fasten. Therefore, the leakage of a single plate heat exchanger will also lead to problems such as low heat transfer efficiency of plate heat exchanger in the heating industry as a whole. Three: Hydraulic balance, the low temperature side is connected to the indoor system of the secondary network user. In the heating commissioning process, it is necessary to focus on debugging the hydraulic balance to ensure the heating effect. If there is a problem with the hydraulic balance adjustment, it will directly cause heating problems.

The above are several reasons for the low heat transfer efficiency of plate heat exchangers in the heating industry. Therefore, the heat exchange equipment used in the heating industry needs to be professional in terms of design, installation, use and maintenance to achieve the desired effect.
