AI Technical Summary

Technical Problem

The water temperature control method of heat pump units is difficult to dynamically adapt to actual operating conditions and cannot accurately respond to real-time changes in load during building use, resulting in poor accuracy of indoor temperature regulation.

Method used

By acquiring the ambient temperature, inlet water temperature, and outlet water temperature of the heat pump unit, the target building load demand and the inlet and outlet water temperature difference are determined. The output power of the water pump is controlled based on the target water circulation flow rate, and the operating frequency is controlled by the deviation between the target outlet water temperature and the current outlet water temperature, so as to achieve precise regulation of the outlet water temperature.

Benefits of technology

This improves the accuracy and stability of the heat pump unit's indoor temperature regulation, ensuring precise control of room temperature.

Abstract

The application discloses a control method and device of a heat pump unit, a storage medium and an electronic device. The method determines a target building load demand of the heat pump unit according to an ambient temperature where the heat pump unit is located, determines a target water inlet-outlet temperature difference according to a current water inlet temperature, and determines a target water circulation flow of the heat pump unit according to the target building load demand and the target water inlet-outlet temperature difference. The output power of a water pump in the heat pump unit is controlled based on the target water circulation flow, and a target water outlet temperature is determined. The operation frequency of the heat pump unit is controlled based on a temperature deviation value of the target water outlet temperature and the current water outlet temperature, so that the water outlet temperature of the heat pump unit reaches the target water outlet temperature. The heat pump unit is controlled to operate through the target building load demand, the target water circulation flow is adjusted through the variable water inlet-outlet temperature difference, the water temperature is dynamically adjusted to match the temperature difference state between the indoor environment and the set temperature, and the accuracy of the heat pump unit in adjusting the temperature of the indoor environment can be improved.
