AI Technical Summary
Existing constant-temperature heat pump units for aquaculture have simple filtration structures that are prone to clogging heat exchangers when faced with water sources containing impurities and suspended solids, leading to frequent unit failures and reduced heat exchange efficiency.
A constant-temperature heat pump unit including a filter screen, a sealing connection, and a flow distribution system was designed. The filter screen performs dual filtration of water, the sealing connection improves the sealing effect, and the flow distribution system enables precise control of water supply and temperature monitoring, ensuring water quality and preventing impurities from entering the heat pump body.
It effectively prevents impurities from entering the heat pump unit, improves heat exchange efficiency, reduces unit failures, ensures the stability of water supply and the accuracy of temperature control, and is suitable for the temperature regulation needs of different aquaculture scenarios.
