Board replacement installation problem
Thread Content
One central air-conditioning system, no expansion water tank, variable frequency water replenishment. I would like to ask whether it is better to install the plate replacement at the water outlet of the circulation pump or at the water inlet? What is the principle? Thanks in advance :)
No one can help me? :'( :'( :'( :'( :'( :'(
I think it should be installed at the outlet of the pump. I can’t tell you the specific principle. I just speculated based on the process of installing an ammonia refrigeration system. In this system, the cooler is located at the outlet of the screw compressor. Haha, my personal opinion may be wrong.
It is better to install it at the water inlet first.； As the power unit of a closed-loop circulation system, its position does not make much difference to the circulation effect. in addition: Considering the temperature difference before and after the circulating medium, as well as the requirements and pros and cons of the circulating pump, the differences are obvious. All things considered ； It is better to install it at the water inlet.
Our company generally installs it on the water inlet side, thinking that the return water pressure of the system is lower than the outlet water pressure, and the head of the water replenishing pump is low, which saves energy!
It is usually installed at the outlet of the circulating water pump.
It is better to install it at the water inlet. Installing it at the water outlet will affect the lift and pressure of the pump.
