Detailed Description
The utility model firstly provides a refrigeration system for a refrigerator-freezer having at least one storage compartment for accommodating goods and a storage tank 30 for water.
Fig. 1 is a schematic block diagram of a refrigeration system for a refrigeration freezer in accordance with one embodiment of the present invention. The refrigeration system 10 of the present invention comprises a compressor 11, a compartment condenser 12, a throttling device 13 and a compartment evaporator 14 connected in sequence by refrigerant lines. The compartment evaporator 14 is connected to the return air pipe section 111 of the compressor 11 and is used for providing cold energy to the at least one storage compartment. That is, the refrigeration system 10 of the present invention is a compression refrigeration cycle.
Specifically, the compressor 11 serves to compress a low-temperature and low-pressure refrigerant gas from the return gas pipe section 111 thereof into a high-temperature and high-pressure gas. The high-temperature high-pressure air flow flows to the compartment condenser 12, and is cooled by the compartment condenser 12 to become low-temperature low-pressure liquid which is sent to the throttling device 13. The throttle device 13 is used to throttle and decompress the refrigerant. The throttled and decompressed refrigerant flows to the compartment evaporator 14, rapidly absorbs heat, evaporates and vaporizes, and the vaporized refrigerant flows back to the compressor 11, thereby completing a cycle. In this cycle, the compartment condenser 12 transfers heat from the high temperature, high pressure refrigerant to the ambient air. The compartment evaporator 14 transmits the cold energy to the storage compartment, so that the purpose of cooling and refrigerating the storage compartment is achieved.
In particular, the refrigeration system 10 also includes a waterbox condenser 15 and a waterbox evaporator 16. The tank condenser 15 is provided in the water storage tank 30, and is connected between the compressor 11 and the throttle device 13 in parallel with the compartment condenser 12. The tank evaporator 16 is disposed in the water storage tank 30, and is connected between the throttle device 13 and the compressor 11 in parallel with the compartment evaporator 14.
The refrigeration system 10 for a refrigerating and freezing apparatus of the present invention includes a tank condenser 15 and a tank evaporator 16 provided in a water storage tank, in addition to a compressor 11, a compartment condenser 12, a throttling device 13, and a compartment evaporator 14 which are provided in a conventional compression refrigeration system, and the tank condenser 15 is connected in parallel with the compartment condenser 12 and the tank evaporator 16 is connected in parallel with the compartment evaporator 14.
From this, when the storage water tank needs hot water, the refrigerant that comes out from compressor 11 can flow to water tank condenser 15 to the heat that utilizes water tank condenser 15 to give off heats water, neither influences the refrigeration of storing room, has utilized the heat that is used for carrying out the condenser that cools down to the refrigerant again effectively, avoids the energy waste.
When the storage tank requires cold water, the refrigerant from the compressor 11 can flow all the way to the compartment condenser 12 to avoid the refrigerant flowing to the tank condenser 15 causing the heat dissipated by the tank condenser 15 to be transferred to the storage tank. And at least a portion of the refrigerant flowing from the throttling device 13 may flow to the tank evaporator 16 to thereby utilize the portion of refrigerant to lower the temperature of the water in the storage tank. That is to say, the refrigerant flowing out of the throttling device 13 can flow to the water tank evaporator 16 completely, at the moment, the storage chamber is not refrigerated, and the refrigerating efficiency of the water storage tank is higher; the refrigerant from the throttle device 13 can also be diverted to the tank evaporator 16 and the compartment evaporator 14, so that the storage tank and the storage compartment are cooled simultaneously.
It can be seen that the energy utilization ratio of the refrigeration system 10 of the present application is very high, and the refrigeration and freezing device can be integrated with the functions of storing, supplying cold water and supplying hot water to various household appliances, so that the types and the number of the household appliances can be reduced, and the occupation of too much indoor space can be avoided.
Further, the refrigeration system may further include a dry filter for filtering trace impurities and contaminants that may be generated in the system due to a manufacturing process or long-term use of mechanical wear, and trace moisture that may exist in the system, so as to improve the purity of the refrigerant.
Further, the refrigeration system may also include a first control valve 17. The first control valve 17 is used to control the on/off and/or the refrigerant flow rate of a first refrigerant flow path between the compartment condenser 12 and the compressor 11 and a second refrigerant flow path between the tank condenser 15 and the compressor 11. Specifically, the first control valve 17 may control one of the first refrigerant flow path and the second refrigerant flow path to be open and the other to be closed. The first control valve 17 may control the flow rate of the refrigerant in the first refrigerant flow path and the second refrigerant flow path. That is, the first control valve 17 can control the refrigerant to flow to the first refrigerant flow path entirely, to flow to the second refrigerant flow path entirely, or to flow to the first refrigerant flow path partially to flow to the second refrigerant flow path.
Thus, when the storage tank requires hot water, most or all of the refrigerant can be controlled to flow to the tank condenser 15 to improve the efficiency of heating the storage tank, and the speed of heat absorption by the water is much higher than that by air, so that the efficiency of cooling the storage compartment can be indirectly improved.
Specifically, the first control valve 17 may be a three-way valve and includes a first inlet port 171, a first outlet port 172, and a second outlet port 173. The first inlet end 171 communicates with the discharge pipe section 112 of the compressor 11, and the first outlet end 172 and the second outlet end 173 communicate with the refrigerant inlet of the compartment condenser 12 and the refrigerant inlet of the bank condenser 15, respectively. The first inlet end 171 and the first outlet end 172, and the first inlet end 171 and the second outlet end 173 are selectively conducted, and the first outlet end 172 and the second outlet end 173 are closed and not conducted. This makes it possible to open and close the first refrigerant flow path and the second refrigerant flow path and/or control the flow rate of the refrigerant.
In some embodiments, the refrigeration system 10 also includes a second control valve 18. The second control valve 18 is used to control the opening/closing and/or the refrigerant flow rate of the third refrigerant flow path between the compartment evaporator 14 and the throttle device 13 and the fourth refrigerant flow path between the tank evaporator 16 and the throttle device 13. Specifically, the second control valve 18 may control one of the third refrigerant flow path and the fourth refrigerant flow path to be open and the other to be closed. The second control valve 18 may also control the magnitude of the refrigerant flow in the third refrigerant flow path and the fourth refrigerant flow path. That is, the second control valve 18 can control the refrigerant to flow to the third refrigerant flow path entirely, to flow to the fourth refrigerant flow path entirely, or to flow to the third refrigerant flow path partially, or to flow to the fourth refrigerant flow path partially.
Thus, when the water storage tank needs cold water, most or all of the refrigerant can be controlled to flow to the water tank evaporator 18, so that the efficiency of refrigerating the water storage tank is improved; when the storage chamber needs rapid refrigeration, most or all of the refrigerant is controlled to flow to the chamber evaporator 14, so that the efficiency of refrigerating the storage chamber is improved.
Specifically, the second control valve 18 may be a three-way valve and includes a second inlet port 181, a third outlet port 182, and a fourth outlet port 183. The second inlet port 181 communicates with the refrigerant outlet of the throttling device 13, and the third outlet port 182 and the fourth outlet port 183 communicate with the refrigerant inlet of the compartment evaporator 14 and the refrigerant inlet of the tank evaporator 16, respectively. The second inlet end 181 and the third outlet end 182, and the second inlet end 181 and the fourth outlet end 183 are selectively conductive, and the third outlet end 182 and the fourth outlet end 183 are closed and non-conductive. This makes it possible to open and close the third refrigerant flow path and the fourth refrigerant flow path and/or control the refrigerant flow rate.
In some embodiments, the on-off state of the first control valve 17 and the second control valve 18 can be controlled according to the temperature of water in the water storage tank. A temperature sensor for detecting the temperature of the water contained in the water storage tank is arranged in the water storage tank.
Fig. 2 to 4 are schematic structural views of a refrigeration system according to an embodiment of the present invention in different cycle states. The straight arrows in fig. 2 to 4 indicate the flow direction of the refrigerant.
Specifically, referring to fig. 2, when the actually measured water temperature in the water storage tank is higher than the target water temperature set by the water storage tank, the water storage tank needs to be cooled. At this time, the first outlet end 172 of the first control valve 17 is communicated with the first inlet end 171, and the flow path between the second outlet end 173 and the first inlet end 171 is closed and non-communicated, so that all the refrigerant discharged from the compressor 11 flows to the compartment condenser 12 through the first outlet end 172 of the first control valve 17, and the radiator condenser 15 is prevented from radiating heat into the storage tank. The flow path between the third outlet port 182 and the second inlet port 181 of the second control valve 18 is closed and non-conductive, and the fourth outlet port 183 communicates with the second inlet port 181, so that the entire refrigerant flowing out of the throttling means 13 flows to the tank evaporator 16 through the fourth outlet port 183 of the second control valve 18, thereby rapidly cooling the water in the storage tank.
Specifically, referring to fig. 3, when the actually measured water temperature in the water storage tank is lower than the target water temperature set in the water storage tank, the water storage tank needs to be heated. At this time, the flow path between the first outlet end 172 and the first inlet end 171 of the first control valve 17 is closed and non-conductive, and the second outlet end 173 communicates with the first inlet end 171, so that all of the refrigerant discharged from the compressor 11 flows to the tank condenser 15 through the second outlet end 173 of the first control valve 17, thereby rapidly heating the water in the storage tank. The third outlet end 182 of the second control valve 18 is communicated with the second inlet end 181, and the flow path between the fourth outlet end 183 and the second inlet end 181 is closed and non-communicated, so that all the refrigerant flowing out of the throttling device 13 flows to the compartment evaporator 14 through the third outlet end 182 of the second control valve 18, and the storage compartment is rapidly cooled while the storage tank is rapidly heated, and the energy utilization rate is highest in the case.
Specifically, referring to fig. 4, when the actually measured water temperature in the water storage tank is equal to the target water temperature set by the water storage tank, neither heating nor cooling of the water storage tank is required. At this time, the first outlet end of the first control valve 17 is communicated with the first inlet end 171, and the flow path between the second outlet end 173 and the first inlet end 171 is closed and non-communicated, so that all the refrigerant from the compressor 11 flows to the compartment condenser 12 through the first outlet end 172 of the first control valve 17, and the radiator condenser 15 is prevented from radiating heat into the storage tank. The third outlet end of the second control valve 18 is communicated with the second inlet end 181, and the flow path between the fourth outlet end 183 and the second inlet end 181 is closed and is not communicated, so that all the refrigerant flowing out of the throttling device 13 flows to the compartment evaporator 14 through the third outlet end 182 of the second control valve 18, the storage compartment is rapidly refrigerated, and the storage tank is prevented from being refrigerated.
In some embodiments, when the refrigeration system includes the first control valve 17 and the second control valve 18, only operation of the tank condenser 15 and the tank evaporator 16 may be achieved by the first control valve 17 and the second control valve 18, and thus, the storage tank may have only one region within it in which both the tank condenser 15 and the tank evaporator 16 are disposed.
Fig. 5 is a schematic structural view of a refrigeration system according to another embodiment of the present invention. In other embodiments, when the refrigeration system does not include the first control valve 17 and the second control valve 18, the refrigerant may flow to both the bank condenser 15 and the bank evaporator 16. At this time, the storage tank 30 may define therein a cold water region and a hot water region (two regions separated by a dotted line in fig. 5) which are thermally isolated, the tank condenser 15 being located in the hot water region, and the tank evaporator 16 being located in the cold water region. That is, the bank condenser 15 transfers heat to the water in the hot water zone to raise the temperature of the water in the hot water zone. The tank evaporator 16 is used to absorb heat from the water in the cold water region and cool the water to reduce the temperature of the water in the cold water region. No heat is transferred between the cold water area and the hot water area in the water storage tank, so that hot water and cold water can be simultaneously provided.
