Embodiment Construction

[0024] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0025] Depend on figure 1 As shown, the refrigerator 1 under test is placed in a specified testing environment (the standard temperature is 21° C., and the non-standard temperature is 32° C.), and the internal device 5 is placed in the inner cold chamber 3 of the refrigerator 1 through the bracket 2 of the internal device 5 . According to the needs of temperature measurement, the digital temperature sensor 5c is placed in an appropriate position in the inner cold room 3 of the refrigerator 1, and connected to the internal device 5 through the temperature sensor signal line 5d of the internal device 5. The internal device 5 is connected to an external working power supply through a power cord 4 . The external device 6 is placed in an appropriate position through the external device bracket 6a, the power line 7 of the external device 6 is conne...

Abstract

The invention discloses a device for automatically measuring the practical refrigerating power of a refrigerator and a using method thereof. An internal device (5) used in an internal cooling chamber (3) of the refrigerator (1) comprises an electric heater (5a) and a fan (5b) which are arranged in the internal cooling chamber (3) of the refrigerator (1). The device is characterized in that a measuring device which is used for measuring the electric power consumption of the electric heater (5a) and the fan (5b) and is controlled by a singlechip (5m) is arranged in the internal device (5). The using method comprises the following steps: I, setting a final refrigerating balance temperature in the cooling chamber (3) on the internal device (5); II, powering up the internal device (5) and closing the door of the cooling chamber (3); and III, when the temperature in the cooling chamber (3) is in a balanced state, recording the practical refrigerating power Q of the refrigerator, which is displayed on an external device (6). After the practical refrigerating power of the refrigerator (1) is automatically measured, the load temperature rising time of the cooling chamber (3) in the refrigerator (1) can be also measured.

Description

Technical field: [0001] The invention relates to an automatic measuring device for the practical refrigeration power of a refrigerator and a using method thereof. Background technique: [0002] With the increasing awareness of energy conservation in society, people are increasingly concerned about the efficiency of household appliances. However, for refrigeration equipment such as refrigerators and refrigerators and freezers currently on the market, only the effective volume and power consumption are marked on the nameplate. The amount of cold dissipated from body door cracks, etc.) is not marked. [0003] In fact, the manufacturer only measures the cooling power during the product development process. For the products put on the market, due to the reason of the measurement method and the measuring device, the cooling power cannot be directly measured, and only the cooling rate related to it can be measured. The refrigeration efficiency (practical refrigeration power / power...
