Description

Electricity-saving refrigerator

Technical Field

The utility model relates to a power-saving refrigerator.

Background

In order to save electricity charge, avoiding electricity consumption peaks, the electricity price of domestic electricity in many cities is divided into two time periods by a time-sharing electricity price mode, namely 24 hours a day is divided into 13 hours, namely 8:00-21:00 are called peak periods, and the peak electricity price is 0.55 yuan/kWh; the total of 11 hours from 21:00 to 8:00 a day is called a valley period, and the electricity price of the valley is 0.35 yuan/kWh. The washing machine, the electric water heater, the television and other electric appliances in each household can be manually set to use the night low-valley power, and the refrigerator is a civil product with very wide application and is a household electric appliance which must be operated continuously for 24 hours. According to investigation, the electric quantity of the urban household refrigerator accounts for 40% -60% of the expenditure of household electric charge, is the main electric equipment in the household, is a refrigeration display cabinet of a market or a supermarket, is also a high-energy-consumption electric appliance in summer, and has great significance for the country and the household when the electric quantity is applied to the household refrigerator to shift peak and fill valley.

The conventional refrigerator, freezer and refrigerator have definite running time and compressor on-off time ratio under certain load conditions, namely, when the temperature of the refrigerating chamber or the freezing chamber is higher than the set temperature in normal running of the equipment, the compressor is started for refrigeration, no specific pertinence exists for time, the refrigerator cannot run in different modes according to different time periods, especially in summer, the daytime environment temperature is higher, the evening temperature is lower, the refrigerator dissipates much more heat in daytime than evening, the compressor is frequently started in peak time of daytime power consumption, the phenomenon of less starting in valley time of evening power consumption is caused, namely, the refrigerator of a family pays more expensive peak time electric charge and less pays low valley time electric charge. Even though there is a time-of-use electricity price, the refrigerator may pay more electricity than the refrigerator which does not. For the refrigerated showcases for markets and supermarkets, the compressor is frequently started when the daytime electricity consumption peak occurs, so that the daytime electricity consumption overload of the markets and the supermarkets is caused.
