Background
In the using process of the refrigerator, the evaporator of the refrigerator can generate a frosting phenomenon, and the evaporator is usually defrosted in an electric heating mode in the prior art. The exiting of the defrosting program is judged by the temperature of the defrosting sensor, however, the placing position of the defrosting sensor in the design stage of the refrigerator usually depends on experience, so that the problem that the residual ice is frozen when the temperature of the defrosting exiting temperature is reached is avoided, and the residual ice may be frozen in large blocks and block the evaporator when the refrigerator is used for a long time by a user, so that the normal use of the refrigerator is influenced.

However, the temperature of the indoor environment of the refrigerator is only thirty or more degrees at the highest, and even the temperature of the air in the compressor compartment is not about forty degrees at the highest, so that the heat which can be provided by the air is limited, and the effect of assisting defrosting of the evaporator is not ideal.

Optionally, the heat storage agent is arranged to remain in a liquid state within a preset temperature range and remain in a gaseous state beyond a preset temperature threshold; wherein
The preset temperature range is-30-20 ℃, and the preset temperature threshold is 20 ℃.
According to a second aspect of the present invention, there is also provided a refrigerator comprising a refrigeration system as described in any of the above.
When the refrigerator operates, the refrigerant is compressed into high-temperature and high-pressure gaseous flow through the compressor, in the prior art, the high-temperature and high-pressure gaseous flow enters the condenser through the exhaust pipe and the evaporation pan to exchange heat with the outside, and the high-temperature refrigerant can be partially cooled by the defrosting water discharged by the freezing or refrigerating drain pipe when passing through the evaporation pan. However, the flow rate of the defrost water is small and the generation is not continuous, and thus the temperature of the refrigerant cannot be effectively lowered. More importantly, the heat in the section of the line from the compressor discharge to the condenser inlet is not used efficiently, but is wasted.
The applicant of the present invention has recognised that the discharge temperature of the compressor varies greatly between different ambient temperatures. For example, when the ambient temperature is 43 ℃, the discharge temperature of the compressor can be as high as 90 ℃; when the ambient temperature is 10 ℃, the discharge temperature of the compressor is about 20 ℃. But in any event the discharge temperature of the compressor is higher than ambient temperature and much higher than the compartment temperature and evaporator temperature during refrigeration.
For this reason, the refrigeration system of the present application is designed with a heat storage device storing a heat storage agent and a heat storage agent line connected to the heat storage device, in addition to the conventional compressor, condenser, throttling element and evaporator, and with a discharge pipe section passing through the heat storage device and immersed in the heat storage agent so that the heat storage agent line is disposed adjacent to or near the heat demand parts of the refrigerator. Therefore, when the compressor normally operates, the exhaust pipe section continuously sprays high-temperature and high-pressure gaseous refrigerant, and the refrigerant and the heat storage agent perform sufficient heat exchange when flowing through the heat storage device so as to store heat in the heat storage agent. When the compressor is stopped, the heat storage agent can be promoted to flow in the heat storage agent pipeline, and when the heat storage agent flows through the position near the heat demand part, the heat storage agent can exchange heat with air or parts around the heat demand part, so that heat is transferred to the heat demand part, and the purpose of heating the heat demand part is achieved. Since the temperature of the refrigerant in the discharge pipe section is very high and the heat of the refrigerant can be continuously transferred and stored in the heat storage agent while the compressor is operating, the utilization efficiency of the heat of the refrigerant in the discharge pipe section is very high, so that the heat requiring parts can be efficiently heated by the heat storage agent.
Meanwhile, the refrigerant in the exhaust pipe section is fully cooled when flowing through the heat storage device, so that the temperature of the refrigerant flowing into the condenser is reduced, and the problem of serious heating of a side plate of the refrigerator can be avoided.
Further, this application still is equipped with the vortex device that is used for disturbing heat accumulation agent in heat accumulation device, and the vortex device can be opened when the compressor normal operating to make exhaust pipe section and more heat accumulation agent direct contact, thereby avoid only having the higher heat transfer efficiency between refrigerant and the heat accumulation agent that influences in the exhaust pipe section of partial heat accumulation agent temperature, improved heat transfer effect and heat exchange efficiency between refrigerant and the heat accumulation agent.
Further, the section of this application in the heat accumulation device with the exhaust pipe section sets the circuitous shape that extends of S type to, can increase the area of contact between exhaust pipe section and the heat accumulation agent to greatly increased the heat transfer area between refrigerant and the heat accumulation agent, further improved heat transfer effect and heat exchange efficiency between refrigerant and the heat accumulation agent.

Detailed Description
The present invention first provides a refrigeration system for a refrigerator, and fig. 1 is a schematic structural view of the refrigeration system for a refrigerator according to one embodiment of the present invention. Referring to fig. 1, the refrigeration system 10 of the present invention includes a compressor 110, a condenser 120, a throttling device 130, and an evaporator 140 connected in series by a refrigerant line 190, the refrigerant line 190 including a discharge tube segment 150 connected to a discharge port of the compressor 110. Specifically, a discharge tube segment 150 is located between the compressor 110 and the condenser 120.
In particular, the refrigeration system 10 also includes a thermal storage device 160 and a thermal storage agent line 170. The heat storage device 160 stores therein a heat storage agent, and has an outlet 162 for flowing out the heat storage agent and an inlet 161 for flowing in the heat storage agent. A heat storage agent line 170 is connected between the outlet 162 and the inlet 161 for circulating the heat storage agent. The exhaust pipe section 150 passes through the heat storage device 160 and is at least partially immersed in the heat storage agent in the heat storage device 160, and a part of the pipe section of the heat storage agent pipe 170 is disposed adjacent to or in the vicinity of the heat demand parts of the refrigerator requiring heat. Specifically, the outlet 162 and the inlet 161 may be opened on two opposite side walls of the thermal storage device 160, respectively, with the outlet 162 near the top of the thermal storage device 160 and the inlet 161 near the bottom of the thermal storage device 160.
Thus, when the compressor 110 is normally operated, the discharge pipe section 150 continuously discharges the high-temperature and high-pressure gaseous refrigerant, and the refrigerant exchanges heat with the heat storage agent sufficiently while flowing through the heat storage device 160 to store heat in the heat storage agent, which is a heat absorption stage of the heat storage device 160. When the compressor 110 is stopped, the heat storage agent can be driven to flow in the heat storage agent pipeline 170, and when the heat storage agent flows near the heat demand component, the heat storage agent can exchange heat with air or components around the heat demand component to transfer heat to the heat demand component, so that the purpose of heating the heat demand component is achieved. This is the heat release phase of the thermal storage device 160, which occurs during the compressor 110 shutdown or the first compressor shutdown after evaporator defrost.
Since the temperature of the refrigerant in the discharge pipe section 150 is high and the heat of the refrigerant can be continuously transferred and stored in the heat storage agent while the compressor 110 is operating, the heat storage agent releases the stored heat to the heat demand part while the compressor is stopped, and thus the utilization efficiency of the heat of the refrigerant in the discharge pipe section 150 is very high.
To the refrigerator that has the curb plate formula condenser, heat load is very big under high temperature environment, and the condenser temperature is higher and less with ambient temperature's difference in temperature, is unfavorable for condenser and external heat transfer, can lead to the refrigerator curb plate to generate heat or even scald one's hand, is very not good experience to the user. The heat storage device 160 of the present application can stably and continuously provide the heat storage agent of a lower temperature to exchange heat with the refrigerant of a higher temperature during the shutdown of the compressor 110, so that the refrigerant entering the condenser is effectively cooled in advance, and therefore, the temperature of the refrigerant flowing into the condenser 120 is lowered, and the problem of serious heat generation of the side plate of the refrigerator can be avoided.
In addition, the heat storage agent in the heat storage device 160 directly flows to a position near the heat demand component through the heat storage agent pipeline after absorbing the heat of the exhaust pipe section 150, so that the heat transfer link is less, and the heat loss rate is lower.
In some embodiments, refrigeration system 10 further includes an actuation pump 181, and actuation pump 181 is disposed in heat storage agent line 170 to actuate the circulation of heat storage agent between heat storage agent line 170 and heat storage device 160. Further, a drive pump 181 may be provided adjacent the outlet 162 of the thermal storage device 160 to continuously pump the thermal storage agent during the heat release phase of the thermal storage device 160. It is understood that the driving pump 181 is kept in a stopped state during the heat absorption phase of the heat storage device 160.
Specifically, the drive pump 181 may be a small-sized high-pressure water pump, which can meet the demand for pumping the heat storage agent and occupies a small space.
Fig. 2 is a schematic configuration diagram of a partial structure of a refrigeration system according to an embodiment of the present invention. In some embodiments, the heat demand components of the refrigerator 1 may include the evaporator 140, and the first section 171 of the heat storage agent pipe 170 surrounds the evaporator 140 for at least one revolution. That is, the driving pump 181 may be activated when the evaporator 140 needs defrosting to assist defrosting of the evaporator 140 by the heat absorbed by the heat storage device 160. In order to solve the problem that residual ice still exists on the evaporator after electric heating defrosting is finished, the driving pump 181 can be started during the period from the electric heating defrosting to the compressor restarting (during the compressor delayed starting), so that the heat storage agent after heat absorption flows to the first partial pipe section 171, and the high-temperature heat storage agent in the first partial pipe section 171 is used for heating and melting ice particles and residual ice possibly existing on the evaporator 140, thereby realizing the effect similar to air defrosting and reducing the electric energy consumed by the evaporator defrosting.
Specifically, since the freezing chamber has a lower temperature and the freezing evaporator is defrosted by simply using electric heating, the phenomenon of residual ice in the freezing evaporator is more prominent, and for this reason, the evaporator 140 may be a freezing evaporator. That is, the heat storage device 160 of the present invention is more suitable for defrosting the refrigeration evaporator.
Fig. 3 is a schematic structural view of a refrigerator according to one embodiment of the present invention. In some embodiments, the refrigerator 1 includes a refrigerating compartment and a freezing compartment, which may be below the refrigerating compartment. Specifically, the freezer compartment may include two portions, a freezer compartment 210 and a freezer drawer 220. The freezing compartment 210 is opened or closed by a freezing door body. The heat requiring components of the refrigerator 1 may further include a door seal 202 of the freezing compartment, a center sill 203 between the refrigerating compartment and the freezing compartment, and a dew removing tube 204 disposed within the foaming layer.
The applicant has appreciated that when the refrigerator 1 is operated in a high temperature and high humidity environment, the on-state rate of the compressor 110 is high and the freezing door seal is prone to generate condensation. When the compressor 110 is stopped, the temperature of the dew-removing pipe is lowered and cannot effectively heat the door seal of the freezing chamber, and when the sealing performance of the door seal is poor, the air with high temperature and high humidity is easy to generate dew when meeting cold.
For this reason, referring to the schematic block diagrams of the partial freezing chamber and the partial refrigerating system shown in fig. 4 and 5 in different orientations, the present application arranges the second partial pipe section 172 of the heat storage agent pipeline 170 adjacent or adjacent to the freezing door seal 202, the center sill 203 and the dew-removing pipe 204, and uses the second partial pipe section 172 to guide the heat storage agent after absorbing heat to the freezing door seal 202, the center sill 203 and the dew-removing pipe 204, so as to achieve the continuous heating of the freezing door seal, the center sill and the dew-removing pipe during the shutdown of the compressor 110, similar to the heating effect generated by the continuous operation of the compressor 110. Since the refrigeration door seal is in a continuously heated state, condensation is not easily generated, and the heat storage device 160 can reduce the startup time of the compressor 110 in a high-temperature and high-humidity environment to some extent, which is beneficial to reducing energy consumption.
In some embodiments, the first portion 171 and the second portion 172 of the heat storage agent line 170 are disposed in parallel. That is, the heat storage agents flowing through the first section 171 and the second section 172 are independent of each other, so that the problem that the temperature of the heat storage agent in the downstream section is increased due to the series connection of the first section 171 and the second section 172, which results in poor heat exchange with the heat demand unit, can be avoided.
Further, the refrigeration system 10 further includes a solenoid valve 182 disposed in the heat storage agent line 170, and the solenoid valve 182 is used to control the on/off between the first partial pipe section 171 and the outlet 162, and between the second partial pipe section 172 and the outlet 162. That is, the flow of the heat storage agent to one of the first and second partial pipe sections 171 and 172 may be controlled by the solenoid valve 182 to defrost only the evaporator 140 or to heat only the door seal, the center sill, and the dewing pipe; the diversion of the heat storage agent may also be controlled by the solenoid valve 182 and flows to the first section 171 and the second section 172, respectively, to defrost the evaporator 140, heat the door seal, the center sill, and the dew removal pipe at the same time.
Specifically, the solenoid valve 182 may be a three-way valve, three openings of which are in direct or indirect communication with the outlet 162 of the thermal storage device 160, the first partial pipe section 171, and the second partial pipe section 172, respectively.
Further, the driving pump 181 may be disposed on a pipe section of the heat storage agent line 170 between the outlet 162 and the solenoid valve 182. Accordingly, the heat storage agent can be supplied to one of the first section 171 and the second section 172 or both of the first section 171 and the second section 172 by one driving pump 181, and the structure of the refrigeration system 10 is simplified.
The flow path of the heat storage agent will be described in detail in one of the cases below.
When the compressor 110 is stopped, the driving pump 181 is started to suck the heat storage agent of the heat storage device 160, the heat storage agent flows out through the outlet 162 of the heat storage device 160 and is divided into two branches by the electromagnetic valve 182, one branch flows to the first partial pipe section 171 to defrost the evaporator 140 and then returns to the heat storage device 160 through the inlet 161 of the heat storage device 160, and the other branch flows to the second partial pipe section 172 to heat the door seal, the center sill and the dew removing pipe and then returns to the heat storage device 160 through the inlet 161 of the heat storage device 160. Of course, the two branches of the heat storage agent may be combined before flowing through the inlet 161 of the heat storage device 160 and then returning to the heat storage device 160 through the inlet 161 of the heat storage device 160.
In some embodiments, a flow perturbation device 163 for controllably perturbing the heat storage agent is provided within the heat storage device 160. The turbulent flow device 163 may be opened when the compressor 110 is normally operated, that is, at the heat absorption stage of the heat storage device 160, to urge the exhaust pipe section 150 to directly contact with more heat storage agent, so as to avoid that the heat transfer efficiency between the refrigerant and the heat storage agent in the exhaust pipe section 150 is affected due to the high temperature caused by the heat exchange between only part of the heat storage agent and the exhaust pipe section 150, and improve the heat exchange effect and the heat exchange efficiency between the refrigerant and the heat storage agent.
Further, the flow disturbance device 163 may be disposed at the bottom inside the heat storage device 160 to optimize the flow disturbance effect thereof. In particular, the spoiler 163 may be a water wheel.
Fig. 6 is a schematic structural view of a thermal storage device and an evaporation pan according to an embodiment of the present invention. In some embodiments, the section of the exhaust pipe segment 150 located in the thermal storage device 160 is distributed in an S-shaped winding manner. That is, the section of the exhaust pipe section 150 in the heat storage device 160 is set to be in an S-shaped extending shape, so that the contact area between the exhaust pipe section 150 and the heat storage agent can be increased, the heat exchange area between the refrigerant and the heat storage agent is greatly increased, and the heat exchange effect and the heat exchange efficiency between the refrigerant and the heat storage agent are further improved.
In some embodiments, refrigeration system 10 further includes an evaporator pan 183, evaporator pan 183 configured to collect condensate produced by evaporator 140. The heat storage device 160 and the evaporation pan 183 are both arranged in the compressor bin 201 where the compressor 110 is located, and a refrigerant pipeline extending from the heat storage device 160 penetrates through the evaporation pan 183 and then is connected with the condenser 120. Thereby, the refrigerant between the compressor 110 and the condenser 120 can be further cooled by the condensed water in the evaporating dish 183. Meanwhile, the heat storage device 160 does not directly contact the compressor 110, the vibration generated by the compressor 110 is not transmitted to the heat storage device 160, and the liquid heat storage agent in the heat storage device 160 partially absorbs the vibration energy from the discharge duct section 150, thereby reducing the vibration and noise of the entire refrigerator 1.
Specifically, the refrigerant lines may be distributed in the evaporating dish 183 so as to extend in an S-shaped winding manner.
In some embodiments, the heat storage agent is configured to remain in a liquid state within a predetermined temperature range and remain in a gaseous state beyond a predetermined temperature threshold. The preset temperature range can be-30-20 ℃, and the preset temperature threshold can be 20 ℃. Thus, after heat exchange with the heat demand parts, the heat storage agent in the heat storage agent line 170 can continue to flow in a liquid state so as to be returned to the heat storage device 160; the heat storage agent in the heat storage device 160 may be rapidly converted into a high-temperature gaseous state after absorbing heat of the refrigerant in the discharge pipe section 150. The gaseous flow is more favorable for circulation in the piping than the liquid flow and can release a large amount of latent heat of phase change, so that the optimum heat exchange effect can be obtained.
The utility model also provides a refrigerator, and the refrigerator 1 of the utility model comprises the refrigeration system 10 described in any one of the embodiments.
Further, the refrigerator 1 further includes a cabinet 20, and the refrigeration system 10 is distributed in the cabinet 20.
Specifically, the cabinet 20 may define at least one storage compartment therein, for example, a refrigerating compartment and a freezing compartment. Accordingly, the refrigerator 1 further includes a refrigerating door body for opening and closing the refrigerating chamber and a freezing door body for opening and closing the freezing chamber.
It will be understood by those skilled in the art that the refrigerator 1 of the present invention is a refrigerator in a broad sense, and includes not only a conventional refrigerator in a narrow sense but also a refrigerator, a refrigerator car, an ice chest or other refrigerating and freezing apparatus having a refrigerating and/or freezing function.
