The refrigerator products have great differences in actual use environments due to different use environments and seasonal changes of users. For example, the environmental temperature in the southern area is higher, the environmental temperature in the northern area is lower, the environmental temperature in summer is high, the environmental temperature in winter is low and the like, the refrigerator is changed by the environmental temperature, and the refrigerating performance can be affected to a certain extent. In particular, when the refrigerator is used, and the ambient temperature is too low, the evaporator end may have a problem of lack of refrigerant.

To solve the problem of lack of refrigerant, it is common to start with both increasing the refrigeration capacity and reducing the heat loss. On one hand, the large-displacement compressor is needed to be adopted for increasing the refrigerating capacity of the refrigerator, the method has high power of the compressor, and the energy consumption of the refrigerator is increased, so that the efficiency of the compressor is required to be improved to meet the energy consumption requirement, the energy consumption is increased, and the use cost is increased. On the other hand, the heat loss is reduced by improving the door body structure and the door seal sealing effect. In actual operation, the scheme cannot eliminate the influence of the temperature rise of the switch door, and the energy consumption is also increased, so that the use cost is increased.

In order to solve the energy consumption problem, in practical use, a mode of adding an adjusting device in the refrigerator is adopted to increase or decrease the refrigerant in the refrigerating system. Namely, the refrigerator comprises a condenser, an evaporator and an adjusting device, and the condenser, the evaporator and the adjusting device are connected through pipelines. The adjusting device comprises a liquid storage tank. And the regulating device is used for adding the refrigerant into the refrigerating system to realize the refrigerant supplementation of the refrigerating system. However, in use, the amount of the refrigerant shortage cannot be accurately determined, so that there is a possibility that the refrigerant is excessively added when the refrigerant is added. If the refrigerant is excessively added, the cooling effect is affected.

The embodiment of the disclosure provides a refrigerator, comprising: a refrigeration system and a bypass branch 6.

Referring to fig. 1, the refrigeration system includes a compressor 1, a condenser 2, and an evaporator 3, which are sequentially connected by piping.

Referring to fig. 2 and 3, a bypass branch 6 is connected in parallel between the discharge side of the compressor 1 and the inlet of the condenser 2.

A discharge pipe 9 is provided between the discharge side of the compressor 1 and the inlet of the condenser 2, and when an excessive amount of refrigerant in the refrigeration system is detected, a part of the refrigerant in the discharge pipe 9 is conducted to the bypass branch 6, and the bypass branch 6 accommodates a part of the refrigerant.

Further, the refrigerant discharged from the exhaust port of the compressor 1 is in a high temperature and high pressure state, and when the refrigerant is too much, the condenser 2 cannot radiate the too much high temperature and high pressure refrigerant to an ideal temperature, thereby reducing the refrigerating effect of the refrigerator, and easily causing frequent start and stop of the compressor 1 to affect the service life of the compressor 1. Part of the high-temperature and high-pressure refrigerant is led into the bypass branch 6, and the bypass branch 6 is utilized to radiate the part of the high-temperature and high-pressure refrigerant, so that the heat radiation of the condenser 2 is assisted, the refrigerating effect of the refrigerator is improved, the frequent starting and stopping of the compressor 1 is avoided, and the service life of the compressor 1 is prolonged.

It is conceivable, with reference to fig. 2 and 3, that the refrigerator further comprises a valve 5 for controlling the connection or disconnection of the bypass branch 6 to the exhaust pipe 9.

When the refrigerator works normally, the valve 5 closes the bypass branch 6 and is disconnected with the exhaust pipe 9; when there is too much refrigerant in the refrigeration system, the valve 5 opens the bypass line to the discharge line 9.

Further, the bypass branch 6 can be made of a material with high heat exchange efficiency.

Optionally, the pipeline comprises: the air return pipe 8, the air return pipe 8 is connected between the air return side of the compressor 1 and the outlet of the evaporator 3, and the bypass branch 6 is arranged corresponding to the air return pipe 8 so as to exchange heat with the air return pipe 8.

When the bypass branch 6 is utilized to radiate part of the high-temperature and high-pressure refrigerant, the bypass branch 6 radiates heat outwards. Considering that the refrigerant in the return air pipe 8 between the evaporator 3 and the compressor 1 is in a low temperature state, the return air pipe 8 is easily condensed, and when the refrigerant is too much, the condensation phenomenon is remarkable. At least part of the bypass branch 6 is arranged corresponding to the air return pipe 8, and the heat emitted by the bypass branch 6 is used for heating the air return pipe 8, so that condensation is removed. Thus, on one hand, the heat of the bypass branch 6 is recovered, and the heat utilization rate is improved; on the other hand, condensation is removed from the air return pipe 8, so that the refrigerating effect of the refrigerator is improved.

Optionally, the portion of bypass branch 6 corresponding to muffler 8 is located upstream of the junction of bypass branch 6 and muffler 8.

The bypass branch 6 is used to heat the upstream of the muffler 8 directly, so that when the low-temperature refrigerant enters the muffler 8 from the evaporator 3, the low-temperature refrigerant exchanges heat with the bypass branch 6 and flows into the compressor 1. Because the refrigerant flowing into the muffler pipe 8 from the regulating device 4 is in a gaseous state, the bypass branch 6 does not need to exchange heat with the refrigerant flowing into the muffler pipe 8 from the regulating device 4, so that heat emitted by the bypass branch 6 is concentrated to the upstream of the muffler pipe 8, and the refrigerant flowing into the muffler pipe 8 from the evaporator 3 exchanges heat with the bypass branch 6, thereby improving the heat utilization rate; further, after the refrigerant is heated upstream of the muffler 8, the temperature of the refrigerant flowing through the muffler 8 increases, which helps to prevent condensation on the main body of the muffler 8.

Optionally, the bypass branch 6 is wound outside the muffler 8.

In one embodiment, the bypass branch 6 is spirally wound on the outer side of the muffler 8, a part of distance is reserved between the bypass branch 6 and the muffler 8, and the heat emitted by the bypass branch 6 is utilized to heat the outer surface of the muffler 8, so that condensation on the surface of the muffler 8 is removed.

In another embodiment, the bypass branch 6 is spirally wound on the outer surface of the muffler 8, and the pipe body of the bypass branch 6 is abutted against the outer surface of the muffler 8, so as to directly exchange heat with the muffler 8, that is, the bypass branch 6 directly heats the muffler 8, which is helpful for avoiding the generation of condensation.

It is contemplated that bypass branch 6 may be wrapped around the outside of muffler 8 in any shape, not limited to being helical.

Optionally, a valve 5 is disposed in the bypass branch 6, and is used for controlling the on-off of the bypass branch 6.

During normal operation, the valve 5 controls the bypass branch 6 to be disconnected from the exhaust pipe 9 between the compressor 1 and the condenser 2, and the refrigerant circulates in the refrigeration system pipeline; when an excessive amount of refrigerant in the refrigeration system is detected, the valve 5 controls the bypass branch 6 to communicate with the discharge pipe 9 between the compressor 1 and the condenser 2, and part of the refrigerant enters the bypass branch 6.

In this way, the bypass branch 6 is utilized to accommodate part of the refrigerant, thereby reducing the amount of the refrigerant in the refrigeration system and the working pressure of the compressor 1; the bypass branch 6 is used for carrying out supplementary heat radiation on part of the refrigerant, thereby being beneficial to preventing the overheat of the condenser 2 and also being beneficial to preventing the problem of poor refrigerating effect caused by overheat of the condenser 2.

Optionally, referring to fig. 3, the valve 5 includes a first port 51, a second port 52, and a third port 53. The first port 51 communicates with the discharge side of the compressor 1; the second port 52 communicates with the inlet of the condenser 2; the third port 53 communicates with the inlet of the bypass line. The first interface 51 selectively communicates with one of the second interface 52 and the third interface 53.

When the refrigeration system works normally, the first interface 51 is communicated with the second interface 52, and the first interface 51 is disconnected from the third interface 53, so that the refrigerant circulates normally in the refrigeration system. When an excessive refrigerant charge in the refrigeration system is detected, or the refrigerant charge is excessive, the first port 51 and the third port 53 communicate, and the refrigerant passes from the refrigeration system into the bypass branch 6 through the discharge pipe 9.

The first interface 51 is selectively communicated with one of the second interface 52 and the third interface 53, so that the refrigerator can effectively prevent the refrigerant from entering the bypass branch 6 when in operation, and the amount of the refrigerant in the refrigeration system is kept unchanged, thereby enabling the switch 7 to have the function of interception; and the excessive refrigerant quantity can stably guide the refrigerant into the bypass branch 6, so that the refrigerant quantity in the refrigerating system is regulated, and the refrigerating effect is improved.

Optionally, the refrigerator further comprises: and the controller is connected with the valve 5 and is used for controlling the on-off of the valve 5 according to the difference value between the temperature of the air return pipe 8 and the ambient temperature.

When the ambient temperature is detected to be higher than the temperature of the muffler 8 and the difference value is higher than the third set threshold, too much refrigerant is indicated, and the bypass branch 6 is connected into the exhaust pipe 9 of the compressor 1 by the controller, so that part of the refrigerant is stably led into the bypass branch 6, the refrigerant is stored as a storage pipeline on one hand, and the refrigerant is radiated by the bypass branch 6 on the other hand, so that the heat radiation of the condenser 2 is assisted, and the refrigerating effect is improved.

Optionally, referring to fig. 2 and 4, the refrigerator further includes: and the adjusting device 4 is communicated with the pipeline and is used for adjusting the refrigerant quantity in the refrigerating system.

In case of detecting the lack of refrigerant in the refrigeration system, the regulating device 4 injects refrigerant into the muffler 8, thereby filling the amount of refrigerant in the refrigeration system; when an excessive amount of refrigerant in the refrigeration system is detected, the regulator 4 guides the refrigerant in the refrigeration system into the regulator 4 through the exhaust pipe 9 and stores the refrigerant, thereby reducing the amount of refrigerant in the refrigeration system.

There is a pressure difference between the discharge side and the return side of the compressor 1, and the pressure difference is large, that is, the pressure difference between the discharge pipe 9 and the return pipe is large. The regulating device 4 uses the pressure difference in the refrigerant system piping to achieve automatic regulation of the amount of refrigerant. The automatic filling or subtracting filling is carried out on the refrigerant quantity in the refrigerating system, so that the dynamic adjustment of the refrigerant quantity is realized, the refrigerant quantity meets the refrigerating requirement, and the problem of large upper and lower temperature difference in the refrigerating space is solved.

Alternatively, referring to fig. 4, the adjusting means 4 is connected in parallel with the pipe, and one end of the adjusting means 4 is connected between the discharge side of the compressor 1 and the inlet of the condenser 2, and the other end of the adjusting means 4 is connected between the return side of the compressor 1 and the outlet of the evaporator 3.

Specifically, the discharge pipe 9 side of the compressor 1 is a high-pressure side, and the return pipe 8 side is a low-pressure side. When the refrigerant quantity in the refrigerating system is filled, the regulating device 4 is communicated with the air return pipe 8 of the compressor 1, the regulating device 4 is disconnected with the exhaust pipe 9 of the compressor 1, and at the moment, the refrigerant in the regulating device 4 enters the air return pipe 8 because the air return pipe 8 is a low-pressure end, so that the refrigerant is filled.

When the amount of the refrigerant in the refrigerating system is reduced, the regulating device 4 is communicated with the exhaust pipe 9 of the compressor 1, the regulating device 4 is disconnected with the air return pipe 8 of the compressor 1, and at the moment, the refrigerant in the refrigerating system enters the regulating device 4 through the air return pipe 8 because the exhaust pipe 9 is a high-pressure end, so that the reduction of the refrigerant is completed.

The pressure difference in the refrigerating system is utilized to automatically add and subtract the refrigerant, thereby realizing the automatic adjustment of the refrigerant quantity, being beneficial to the refrigerator to adapt to different working environments, leading the refrigerator to be more widely applicable and improving the refrigerating effect of the refrigerator.

Optionally, the conditioning device 4 has stored therein a gaseous refrigerant.

During refrigeration, the refrigerant is changed into low-temperature low-pressure gaseous refrigerant after heat is absorbed by the evaporator 3, and then is led into the compressor 1, the low-temperature low-pressure refrigerant is compressed into high-temperature high-pressure gaseous refrigerant by the compressor 1, and then is led into the condenser for heat dissipation.

The gaseous refrigerant is stored in the regulating device 4, so that the refrigerant can be directly mixed with the refrigerant in the system when entering the exhaust pipe 9, thereby preventing the liquid refrigerant from entering the compressor 1 to cause the compressor 1 to have liquid impact fault and prolonging the service life of the compressor 1.

Optionally, an adjusting device 4 is arranged between the outlet of the condenser 2 and the inlet of the evaporator 3, the adjusting device 4 comprising a liquid reservoir, a number of valve bodies and an adjusting branch connected in parallel with the liquid reservoir.

One end of the liquid storage tank is communicated with the outlet of the condenser 2, and the other end of the liquid storage tank is communicated with the inlet of the evaporator 3. The valve bodies are respectively used for adjusting the communication between the refrigerating system and the liquid storage tank or between the refrigerating system and the adjusting branch.

When the refrigerating system works normally, the refrigerant circulates in the refrigerating system through the regulating branch, when the refrigerant is required to be filled or subtracted, the refrigerating system is communicated with the liquid storage tank, the refrigerant is added into the refrigerating system from the liquid storage tank, or the refrigerant in the refrigerating system is led into the liquid storage tank for storage, so that the dynamic regulation of the refrigerant quantity is realized, and the refrigerator is facilitated to adapt to different working environments.

In one embodiment, a throttling device such as a capillary tube or a throttle valve is arranged between the condenser 2 and the evaporator 3. Taking the capillary tube as an example, the adjusting means 4 may be arranged between the condenser 2 and the capillary tube, or the adjusting means 4 may be arranged between the capillary tube and the evaporator 3.

Embodiments of the present disclosure provide a method for controlling a refrigerator, comprising: after the primary power-on, the compressor 1 is started and operated. At this time, the refrigerator normally operates, the regulating device 4 is disconnected from the two sides of the compressor 1 by the switch 7, and the regulating device 4 is not connected into a refrigerating system; the bypass branch 6 is disconnected from the discharge pipe 9 and the compressor 1 is shut down when the shutdown temperature range is reached.

The temperatures at the top and bottom of the refrigerated space are collected in real time. And under the condition that the temperature difference value between the top and the bottom in the refrigerating space is larger than or equal to a first set threshold value and the temperature of the top in the refrigerating space is not reduced in the first set time, acquiring environmental temperature data.

And under the condition that the ambient temperature is greater than or equal to a second set threshold value, the compressor 1 is started to operate until the temperature difference between the top and the top in the refrigerating space is smaller than the first set temperature value. And collecting the temperature of the muffler 8 under the condition that the ambient temperature is less than a second set threshold. When the difference between the temperature of the air return pipe 8 and the ambient temperature is greater than a third set threshold value, indicating that the refrigerant is absent in the refrigeration system, communicating the regulating device 4 with the air return pipe 8 of the compressor 1, and adding the refrigerant into the refrigeration system; under the condition that the difference value between the temperature of the air return pipe 8 and the ambient temperature is smaller than or equal to a third set threshold value, the compressor 1 is started to operate until the difference value between the temperature of the top and the temperature of the top in the refrigerating space is smaller than a first set temperature value.

After adding refrigerant to the refrigeration system, a second set time is run. If the detected ambient temperature is less than the temperature of the muffler 8, continuing to fill the refrigerating system with the refrigerant; if the detected ambient temperature is greater than the temperature of the muffler 8 and the difference value is less than or equal to a third set threshold value, the compressor 1 is started to operate until the temperature difference value between the top and the top in the refrigerating space is less than the set temperature value; if the ambient temperature is detected to be greater than the temperature of the muffler 8 and the difference is greater than the third set threshold, this indicates that the refrigerant is over-filled, at which point the bypass branch 6 is connected to the discharge pipe 9 of the compressor 1.

After the bypass branch 6 has been connected to the discharge line 9 of the compressor 1, a third set time is run. If the ambient temperature is detected to be higher than the temperature of the muffler 8 and the difference value is smaller than or equal to a third set threshold value, the compressor 1 is started to operate until the temperature difference value between the top and the top in the refrigerating space is smaller than a first set temperature value; if the detected ambient temperature is greater than the temperature of the muffler 8 and the difference is greater than the third set threshold, it indicates that the refrigerant is still excessive, and at this time, the regulator 4 is connected to the discharge pipe 9 of the compressor 1 to reduce the refrigerant in the refrigeration system. After stopping the back reduction, operating for a third set time, and if the detected ambient temperature is greater than the temperature of the air return pipe 8 and the difference value is less than a fourth set threshold value, normally operating the refrigerator; if the detected ambient temperature is greater than the temperature of the muffler 8 and the difference is greater than or equal to the fourth set threshold, continuing to subtract the refrigerant in the refrigeration system.
