Embodiment Construction

[0023] Such as figure 1 , 2 As shown, the control method proposed by the present invention includes the following steps: detecting the actual operating parameters of the condensing side of the refrigeration system; if the actual operating parameter Tc is less than or equal to the first preset value T1, the condensing side of the refrigeration system performs an adjustment action to maintain The condensing pressure is stable. During the adjustment action on the condensation side of the refrigeration system, the evaporation side of the refrigeration system maintains normal operation, that is, the compressor 1 and the evaporator fan 41 are running. After the adjustment action is performed on the condensation side of the refrigeration system, if the actual operation If the parameter Tc is greater than the third preset value T3, the condensing side of the refrigeration system resumes normal operation.

[0024] It should be noted that the actual operating parameter Tc can be the co...

Abstract

The invention discloses a control method of a refrigeration system, the refrigeration system and a refrigerator. The control method of the refrigeration system includes the following steps of detecting an actual operating parameter of a condensing side of the refrigeration system, judging whether the actual operating parameter is smaller than or equal to a first preset value or not, and if yes, making the condensing side of the refrigeration system execute adjusting actions to keep the condensing pressure stable. By detecting the actual operating parameter of the condensing side of the refrigeration system, comparing the actual operating parameter with the corresponding preset value and making the condensing side execute the adjusting actions when the actual operating parameter is lower than the preset value to keep the condensing pressure stable, the resistance of a throttling device is overcome, the circulating flow of a cold medium is kept, and the normal work of the refrigeration system is ensured.

Description

technical field [0001] The invention relates to the technical field of refrigeration systems, in particular to a control method of the refrigeration system, a refrigeration system and a refrigerator. Background technique [0002] Refrigeration systems are commonly used in air conditioners and refrigerators. Taking refrigerators as an example, the operating environment temperature range is mostly 10°C-43°C. This is the ambient temperature for refrigerators to work normally. When the ambient temperature is too high or too low, The refrigerator may be malfunctioning. In actual use, the ambient temperature is less than 43°C, and the ambient temperature is lower than 10°C. Especially in winter in the north, the heating equipment (air conditioners, electric heaters, etc.) in many non-central heating houses are turned off when there is no one at home, and then turned on after people come back. During the period when the heating equipment is turned off, the room temperature is ofte...
