When the industrial high and low temperature cooling system is in use, what is the general reason if the temperature cannot drop down? How should we deal with such failures?

Let’s first analyze the principles and methods of industrial cooling. The circulating heat transfer medium is different. Generally, the high and low temperature cooling system industry mostly uses direct cooling, while indirect cooling is used, with plate heat exchangers or oil coolers installed inside. In other devices, the heat medium and cooling water source in the system exchange heat in the heat exchanger to reduce the temperature of the medium.

The temperature of the high and low temperature cooling system cannot be reduced. Generally, we conduct inspection and maintenance from the following aspects:

1. A válvula solenoide de arrefecimento está danificada: é necessário verificar se a bobina da válvula solenoide pode funcionar normalmente, se estiver danificada, tem de ser substituída; o painel não emite um sinal de arrefecimento, verificar cuidadosamente o circuito ou utilizar o método de substituição de componentes para verificar.

2. Circuito de falha do circuito: Verificar a parte do circuito do sistema, a tubagem de entrada ou de saída da água de arrefecimento está bloqueada: verificar se a válvula na tubagem da água de arrefecimento está totalmente aberta e assegurar que o fluxo e a pressão da água de arrefecimento são suficientes, e o contactor de aquecimento está preso, Aquecer sempre: observar o estado de arranque do contactor e piorar as peças eléctricas danificadas.

In addition to troubleshooting the above two possible causes of failure, we also need to check whether the cooling plate is replaced or the cooling exchanger is blocked.

The advantage of using indirect cooling is that it has high temperature control accuracy and strong adaptability. It can be applied to the temperature control of high and low temperature cooling system industries. And because the heat transfer medium is cooled first, the cooling impact on the temperature control equipment is relatively small. Of course The disadvantage is that the cooling speed is relatively slow, and the price is more expensive than direct cooling.
