AI Technical Summary

Technical Problem

The refrigerant leak detection unit requires real-time power to ensure safety, but the existing technology of supplying power through the power supply of the refrigeration equipment will result in a large amount of mains power consumption and cannot continue to work in the event of a power outage.

Method used

The refrigerant leak detection unit is powered by an environmental energy harvesting unit, such as a photovoltaic unit. Combined with the power supply of the energy storage unit and the refrigeration equipment, the power supply mode is dynamically adjusted to meet the power consumption demand and ensure that the detection unit works normally under different conditions.

Benefits of technology

It saves mains power resources without increasing the capacity of the energy storage unit, ensures that the refrigerant leak detection unit works normally under different conditions, reduces mains power consumption, and extends the working time after power failure.

Abstract

The application discloses a power supply method and device of a refrigerant leakage detection unit. The power supply method is applied to a refrigeration device, and the power supply method comprises the following steps: determining a current power supply amount of an ambient energy collection unit; if the current power supply amount is greater than or equal to a power consumption amount of the refrigerant leakage detection unit, controlling the ambient energy collection unit to supply power to the refrigerant leakage detection unit; and if the current power supply amount is less than the power consumption amount of the refrigerant leakage detection unit, supplying power to the refrigerant leakage detection unit through a power supply and / or an energy storage unit of the refrigeration device. According to the application, the power supply and the energy storage unit of the refrigeration device are not needed to supply power to the refrigerant leakage detection unit under the condition that the ambient energy collection unit meets the power consumption requirement of the refrigerant leakage detection unit, so that the municipal power resource can be saved under the premise of ensuring the normal work of the refrigerant leakage detection unit.
