AI Technical Summary

Technical Problem

In low-temperature environments, the freezing point of air source heat pump units changes dynamically due to the dynamic changes in antifreeze concentration. The fixed antifreeze protection water temperature value in existing technologies cannot effectively prevent freezing, resulting in poor operational reliability.

Method used

An antifreeze detection branch is installed in parallel on the circulating water line between the air source heat pump unit and the energy-consuming terminal system. An electric heating module is installed on the branch. By detecting the temperature difference between the inlet and outlet water and the fluid flow rate, the target antifreeze protection water temperature is dynamically adjusted to prevent freezing.

Benefits of technology

It effectively improves the antifreeze protection effect of air source heat pump units, enhances operational reliability, and avoids the risk of freezing.

Abstract

This application discloses a control method, device, storage medium, and electronic equipment for an air source heat pump unit, relating to the field of heat pump technology. An antifreeze detection branch is connected in parallel on the circulating water path between the air source heat pump unit and the end-user system. An electric heating module is installed on the antifreeze detection branch. The control method includes: controlling the circulating water path to circulate fluid through the antifreeze detection branch and controlling the electric heating module to start heating; determining the electric heating power value of the electric heating module and the fluid flow rate value of the antifreeze detection branch when the inlet and outlet water temperature difference of the antifreeze detection branch meets a preset stability condition; and determining a target antifreeze protection water temperature value based on the electric heating power value, the inlet and outlet water temperature difference, and the fluid flow rate value, so that the air source heat pump unit operates at the target antifreeze protection water temperature value. This application can improve the antifreeze protection effect of the air source heat pump unit and enhance its operational reliability.
