Problems solved by technology
In the existing refrigeration system, the operation of the compressor is determined by the set temperature in the refrigerator room. When the ambient temperature is low, the normal cold air supply in the freezer room cannot be obtained.
[0003] The above-mentioned existing refrigeration system has the following disadvantages: the set temperature of the refrigerating room is higher than the set temperature of the freezing room, and the compressor operates the refrigerating system according to the set temperature of the refrigerating room. The compressor is stopped
At this time, it is necessary to maintain the freezer at a temperature lower than that of the refrigerator, and the temperature rises due to the stop of the compressor, causing the food stored in the freezer to be destroyed; when the ambient temperature drops below zero, the temperature of the refrigerator also drops below zero. , resulting in the destruction of the food stored in the refrigerator
As a result, in the existing refrigeration system, when the ambient temperature drops below zero, the refrigerator is overcooled, the temperature of the freezer rises, and the function of the refrigeration system cannot be performed normally.

Embodiment Construction
[0015] The content of the technical solution will be further described in detail in conjunction with the accompanying drawings and the implementation manner.
[0016] As shown in the figure, the refrigerating system is provided with a freezer 103 on the upper side, and a refrigerated room 101 on the lower side of the freezer 103 . An ambient temperature sensor 105 is provided on one side of the refrigerating room 101, and its function is to supply cold air based on the detected temperature of the refrigerating room. The lower side of the refrigerator compartment 101 is provided with a machine room 119, and mechanical devices including a compressor 107 are arranged in the machine room 119; a certain space is formed between the refrigerator room 101 and the machine room 119, and a heater 129 is arranged in the space. A cold air supply channel 109 is provided behind the refrigerator compartment 101 and the freezer compartment 103 . The cold air supply flow path 109 is connected ...

A cold storage system able to regulate cold supply according to ambient temp has an ambient temp sensor and a cold storage temp sensor. When ambient temp is lower than a predefined temp. it is sensed by ambient temp sensor to start a heater to raise the temp of cold storage chamber. When the temp of cold storage chamber is higher than a predefined temp. it is sensed by cold storage temp sensor to start a compressor of supplying cold.
Description
technical field [0001] The invention relates to a refrigeration system for adjusting cold air supply according to changes in ambient temperature. Background technique [0002] A general refrigerating system is a system that controls the supply of cold air according to the temperature state inside the refrigerating room. figure 1 As shown, a temperature sensor 5 is provided on one side of the refrigerating room 1, and the cold air supply is controlled based on the temperature detected by the temperature sensor 5, and the temperature detected by the temperature sensor 5 is input to the control unit. When the control unit judges that the temperature detected by the temperature sensor is higher than the set temperature of the refrigerator compartment, it drives the compressor 7 and the fan 13 to generate high-temperature and high-pressure medium through the driving of the compressor, and then exchanges heat with the air around the evaporator 11 to generate cold air. , cool air ...
