AI Technical Summary
In existing technologies, it is difficult to identify reverse fan rotation in HVAC systems, leading to decreased heat exchange efficiency and increased energy consumption. Furthermore, it is difficult to detect fan reverse connection problems in a timely manner during the manufacturing process.
By detecting the temperature difference between the pipe temperature of the first heat exchanger and the ambient temperature, and combining the preset temperature difference conditions and the temperature difference change trend, it is determined whether the fan is reversing. The detection is carried out by utilizing the temperature difference generated during the normal operation of the HVAC system.
It enables accurate and efficient identification of fan reversal within a short period of time during HVAC system operation, avoiding problems such as decreased heat exchange efficiency and increased energy consumption, and eliminating the need for additional complex detection equipment.
