Refrigerator and refrigerating system thereof

Abstract

The invention provides a refrigerator and a refrigerating system thereof. The refrigerating system comprises a compressor, an evaporator and a condenser, the condenser comprises a first condensation pipe and a second condensation pipe, and the refrigerating system is configured in the mode that when the environment temperature of the refrigerator is within a first preset temperature range, an outlet of the first condensation pipe communicates with an inlet of the evaporator, so that a refrigerant discharged from an outlet of the compressor enters the evaporator through condensation of the first condensation pipe, the flow on-way resistance of the refrigerant is small, the power loss of the compressor is smaller, and energy saving is facilitated; and the refrigerating system is further configured in the mode that when the temperature of the environment where the refrigerator is located is within a second preset temperature range, an outlet of the first condensation pipe communicates with an inlet of the second condensation pipe, and an outlet of the second condensation pipe communicates with an inlet of the evaporator, so that refrigerant discharged from the outlet of the compressor is condensed by the first condensation pipe and the second condensation pipe in sequence and enters the evaporator, it is guaranteed that the refrigerant is fully cooled to be in a liquid state in the high-temperature environment, and the refrigeration efficiency of the refrigerator is guaranteed.

Description

technical field [0001] The invention relates to the technical field of refrigeration and freezing storage, in particular to a refrigerator and a refrigeration system thereof. Background technique [0002] In the refrigeration system of existing refrigerators, the condenser is generally formed by bending a long condenser pipe several times. During the refrigeration process of the refrigerator, the high-pressure and high-temperature gaseous refrigerant compressed by the compressor enters the condenser and flows along the entire condenser. The tube flows and is condensed into a high-pressure liquid refrigerant. [0003] When the ambient temperature is low, the refrigerant has been condensed into a liquid state when it does not completely flow through the entire pipe section of the condenser pipe, but it still needs to flow through the entire pipe section of the condenser pipe before it can flow out of the condenser, which relatively increases the amount of refrigerant The resi...

Problems solved by technology

[0003] When the ambient temperature is low, the refrigerant has been condensed into a liquid state when it has not completely flowed through the entire pipe section of the condenser pipe, but still needs to flow through the entire pipe section of the condenser pipe Only after the pipe section can it flow out of the condenser, which relatively increases the resistance of the refrigerant along the way, and the power loss of the compressor is large, which is not conducive to energy saving
