Refrigerator with inverter and power consumption calculation method thereof and power consumption calculation display system

Abstract

The invention provides a refrigerator with an inverter and a power consumption calculation method thereof and a power consumption calculation display system. The refrigerator with the inverter comprises an inverter compressor, a plurality of other electric parts, a main control board and an inverter control board. The power consumption calculation method of the refrigerator with the inverter comprises the steps of A, acquiring working current and working voltage of the inverter compressor from the inverter control board at the preset sampling time intervals within the statistical time quantum; B, acquiring the instant power of the inverter compressor at the sampling time point according to the acquired working current and working voltage; C, calculating the power consumption quantity of the inverter compressor within the statistical time quantum according to each instant power. According to the method, the working current and the working voltage of the inverter compressor are acquired from the inverter control board of the refrigerator with the inverter so as to obtain the power consumption quantity of the inverter compressor; extra sensor is saved; the cost is low; the calculation is accurate.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an inverter refrigerator, a power consumption calculation method for the inverter refrigerator, and a power consumption calculation and display system for the inverter refrigerator. Background technique [0002] Refrigerators are the most commonly used household appliances. Consumers not only pay attention to their functions, but also pay great attention to their power consumption. However, the refrigerators currently on the market only mark the standard energy consumption of the product on the energy-saving label, and this method cannot truly and actually reflect the actual energy consumption during the operation of the refrigerator. Users can only use the product by habit or feeling during use, and often feel that the power consumption of the product is quite different from that provided by the manufacturer. Because it is difficult for consumers to understand t...

Problems solved by technology

One is to use the smart socket to measure and display the power consumption. This method has a great impact on the cost of the refrigerator. The refrigerator must be delivered with a smart socket when it is sold. At the same time, the smart socket can only simply realize the power consumption display of the refrigerator, and cannot Refrigerator Human-Computer Interaction

One is to add a module for measuring power consumption on the basis of the original smart refrigerator. In this way, the power cord of the refrigerator passes through the power consumption module to collect power consumption data before supplying power to the refrigerator, which increases the complexity of the refrigerator manufacturing process. Increased failure rate of refrigerators
