Technical Field

The invention relates to the technical field of heat exchange systems, in particular to a water-cooling refrigerator circulating system.

Background

In daily life, hot water is often used in hot water supply areas such as kitchens and toilets, and a common mode is to provide hot water by heating with a water heater. In the using process, the water faucet needs to be opened for a period of time, and hot water flows out after cold water in the pipeline is discharged. On the one hand, the problem that hot water cannot be discharged in time exists, and on the other hand, the problem of water resource waste also exists.

The refrigerator is used as a refrigerating device, a large amount of heat is released from a condenser in the refrigerating process, and the heat is generally released into the air through conduction, so that the refrigerating process of the refrigerator can be smoothly carried out, and the resource waste exists. The heat generated by the refrigerator can be used for the hot water supply areas in the kitchen or the restroom, thereby saving resources.

The demand for hot water in the kitchen or the toilet is intermittently unstable, and the refrigerating operation of the refrigerator is generally continuous. Sometimes, the heat provided by the condenser of the refrigerator is insufficient to meet the hot water supply requirement, sometimes, the heat of the condenser is excessive and cannot be smoothly discharged, and therefore all devices in the whole circulation system cannot normally operate.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1 to 3, in one embodiment, there is provided a water-cooled refrigerator circulation system 10 including a water-cooled refrigerator 11 and a return pipe 12. One end of the return pipe 12 is connected to an outlet of the water flow side pipe 1111 of the condenser 111 of the water-cooled refrigerator 11 as shown in fig. 4 to 6, and the other end of the return pipe 12 is connected to an inlet of the water flow side pipe 1111. In the process that the water in the water flow side pipe 1111 of the condenser 111 absorbing heat flows in the return pipe 12, the heat is gradually diffused by the natural heat conduction of the return pipe 12, so that the temperature of the water flowing into the water flow side pipe 1111 again is low.

As shown in fig. 1 to 3, the water return pipe 12 passes through a hot water supply area 14, where the hot water supply area 14 refers to a space in a building where hot water needs to be supplied, such as: kitchens, restrooms, public health, and the like. A hot water switching valve 141 is provided at a portion of the return pipe 12 that passes through the hot water supply section 14. The water return pipe 12 is further provided with a circulating driving member 121, and when the water return pipe is used, the circulating driving member 121 and/or the hot water switch valve 141 are/is in an open state. The water-cooling refrigerator circulating system 10 further comprises a cold water inlet pipe 13, and the cold water inlet pipe 13 is communicated with the inlet of the water flow side pipeline 1111.

When the hot water supply area 14 needs hot water, the hot water switch valve 141 is opened, and the hot water in the return pipe 12 flows out from the hot water switch valve 141 for use by a user. The water heater can be used after being opened, and the situation that hot water flows out after cold water is put for a period of time can not exist. The heat released by the condenser 111 of the water-cooled refrigerator 11 is used by the user of the hot water supply area 14, thereby saving resources. In the process of opening the hot water discharge valve 141, the cold water inlet pipe 13 injects cold water into the water flow side pipeline 1111, so that the condenser 111 can normally release heat and normally work. When the hot water switch valve 141 of the hot water supply section 14 is closed, the water absorbed in the water flow-side pipe 1111 flows into the water return pipe 12, the water flows in the water return pipe 12 by the driving of the circulation driving member 121, heat is transferred through the water return pipe 12 during the flow, the heat is released, and the water having a lower temperature after the heat is released flows back into the water flow-side pipe 1111 to absorb the heat, thereby forming a complete closed loop. When the hot water switch valve 141 is closed, the circulation driving member 121 is started, so that the reclaimed water in the closed loop can circulate, and the water-cooled refrigerator 11 can normally work. Therefore, the water-cooled refrigerator 11 can normally operate no matter whether the hot water supply area 14 such as a kitchen and a toilet needs to release hot water or not, and all devices in the water-cooled refrigerator circulating system 10 can normally operate under the condition of saving resources.

Specifically, as shown in fig. 4, the refrigeration system in the water-cooled refrigerator 11 includes a compressor 112, an evaporator 113, a throttling element 114, and a condenser 111, which are connected in sequence. Refrigerant in the refrigeration system flows in refrigerant-side pipes of the compressor 112, the evaporator 113, the throttling element 114, and the condenser 111, a water-side pipe 1111 of the condenser 111 communicates with the return pipe 12, and water in the water-side pipe 1111 absorbs heat of the refrigerant in the refrigerant-side pipe and then enters the return pipe 12. After the water in the water return pipe 12 conducts and releases heat in the flowing process, the water with lower temperature flows into the water flow side pipeline 1111 again to absorb heat, so as to circulate. Or, after the hot water with a high temperature in the return pipe 12 flows out from the hot water switching valve 141, the cold water inlet pipe 13 introduces the cold water with a low temperature into the water flow side pipe 1111 to absorb heat.

Specifically, the condenser 111 may be a shell-and-tube condenser or a double-tube condenser.

Further, in one embodiment, the pipe diameter of the water flow side pipe 1111 is smaller than the pipe diameter of the water return pipe 12, so that the flow rate of the water flow in the water flow side pipe 1111 is higher, but the flow rate in the whole water return pipe 12 is smaller, thereby improving the heat exchange effect.

Specifically, as shown in fig. 5 and 6, in one embodiment, the condenser 111 is located at the top of the water-cooled refrigerator 11, so that the water flow side pipe 1111 of the condenser 111 is connected to the water return pipe 12, thereby improving the convenience of installation. The top of the body 115 of the water-cooled refrigerator 11 is recessed inward to provide an installation space for the condenser 111.

Furthermore, a small section of hose is arranged at each end of the water flow side pipeline 1111 and serves as a transition pipeline section, so that the requirement on the alignment precision when the water flow side pipeline section is connected with the water return pipe 12 is reduced.

As illustrated in fig. 5 and 6, in one embodiment, the refrigeration system has the compressor 112 at the bottom and the evaporator 113 at the back of the freezer compartment.

Further, as shown in fig. 1 to 3, in one embodiment, a first check valve 122 is disposed at an end of the return pipe 12 near the inlet of the water flow side pipe 1111, for preventing water in the cold water inlet pipe 13 from flowing back into the return pipe 12.

In order to enable the condenser 111 to operate normally when the hot water switch valve 141 is opened, the cold water inlet pipe 13 is provided to supply cold water to the water flow side pipe 1111 to absorb heat in the refrigerant side pipe of the condenser 111. The first check valve 122 is provided such that the water in the cold water inlet pipe 13 can flow only into the water flow side pipe 1111 and does not flow back into the return pipe 12.

Further, in one embodiment, to ensure that the circulation driving member 121 and/or the hot water switch valve 141 are/is in an open state during use, the water-cooled refrigerator 11 can work normally. The water-cooling refrigerator circulation system 10 further includes a switching valve sensing member for sensing whether the hot water switching valve 141 is in an open state, the switching valve sensing member being electrically connected to the circulation driving member 121. When the on-off valve sensing member 141 detects that the hot water on-off valve 141 is in a closed state, the circulation driving member 121 electrically connected to the on-off valve sensing member is activated, so that water flows and circulates in the water return pipe 12.

Alternatively, the circulation driving member 121 is directly electrically connected to the hot water switch valve 141. Or, the circulation driving element 121 and the hot water switch valve 141 are both electrically connected to a controller of the water-cooled refrigerator circulation system 10, and the controller uniformly controls the circulation driving element 121 and the hot water switch valve 141, so that at least one of the circulation driving element 121 and the hot water switch valve 141 is in an open state during use.

Further, as shown in fig. 1 to 3, in one embodiment, the water-cooled refrigerator circulation system 10 further includes a supply-area cold water pipe 142, and the supply-area cold water pipe 142 is communicated between the cold water inlet pipe 13 and the hot water switching valve 141.

When the temperature of the water in the water return pipe 12 is too high and the temperature of the water is too high after the hot water switch valve 141 of the hot water supply area 14 is opened, which does not meet the user requirement, the cold water pipe 142 of the supply area can introduce part of the cold water in the cold water inlet pipe 13 into the hot water switch valve 141, so as to adjust the temperature of the water to the temperature required by the user. Specifically, the hot water switch valve 141 may be a switch valve for both cold water and hot water, so that the outlet water temperature can be flexibly adjusted.

Further, as shown in fig. 1, in one embodiment, a portion of the return pipe 12 between the outlet of the water flow side pipe 1111 and the hot water switch valve 141 is a first return pipe section 123. The first water return pipe section 123 is provided with a series water heater 15, and the series water heater 15 is electrically connected with the circulating driving part 121.

The series water heater 15 can further heat the water in the water return pipe 12, and when the series water heater 15 works in a heating state, it is proved that the water temperature provided by the condenser 111 cannot meet the user requirement, the water absorbed with the heat of the condenser 111 in the first water return pipe section 123 needs to be further heated, so that the outlet water temperature at the hot water switch valve 141 is further increased. When the series water heater 15 is turned on, the circulation driving member 121 electrically connected to the series water heater 15 stops operating, in other words, the hot water is required to be completely supplied to the hot water switch valve 141, and is not required to circulate back to the inlet of the water flow side pipeline 1111 through the water return pipe 12, and the inlet of the water flow side pipeline 1111 mainly depends on the cold water inlet pipe 13 to provide cold water to absorb heat in the refrigerant side pipeline.

Specifically, the series water heater 15 may be directly electrically connected to the circulation driving member 121, or indirectly electrically connected through the inductor 1211 as shown in fig. 1, or the series water heater 15 and the circulation driving member 121 may be controlled by a controller.

Further, as shown in fig. 1, in one embodiment, the water-cooled refrigerator cycle system 10 further includes a bypass line 16, and the bypass line 16 is connected in parallel between the inlet and the outlet of the water flow side line 1111. The outlet end of the bypass line 16 is communicated with the return pipe 12 between the outlet of the water flow side line 1111 and the series water heater 15. The bypass line 16 is provided with a bypass switch valve 161, a first switch valve 124 is provided at a portion of the return pipe 12 between an inlet end of the bypass line 16 and an inlet of the water flow-side line 1111, and a second switch valve 125 is provided at a portion of the return pipe 12 between an outlet end of the bypass line 16 and an outlet of the water flow-side line 1111.

The arrangement of the bypass pipeline 16, the bypass switch valve 161, the first switch valve 124 and the second switch valve 125 enables the series water heater 15 to be used normally when the water-cooled refrigerator 11 is replaced. Specifically, in normal use of the water-cooled refrigerator 11, the bypass switch valve 161 is closed, the bypass line 16 is closed, and the first switch valve 124 and the second switch valve 125 are opened, so that the water-cooled refrigerator 11 is communicated with the series water heater 15. When the water-cooled refrigerator 11 needs to be replaced or maintained, or the water-cooled refrigerator 11 does not operate, the bypass switch valve 161 is opened, the bypass pipeline 16 is conducted, the first switch valve 124 and the second switch valve 125 are closed, cold water provided by the cold water inlet pipe 13 can flow into the series water heater 15 through the bypass pipeline 16, so that the series water heater 15 can be normally used, and the hot water switch valve 141 can be opened to provide hot water.

Further, as shown in fig. 2, in another embodiment, the water-cooled refrigerator circulation system 10 further includes a parallel water heater 17 and a water heater cold water pipe 18, an outlet of the parallel water heater 17 is communicated with the hot water switch valve 141, the water heater cold water pipe 18 is communicated between the cold water inlet pipe 13 and an inlet of the parallel water heater 17, cold water provided by the cold water inlet pipe 13 can be directly introduced into the parallel water heater 17 through the water heater cold water pipe 18, and hot water heated by the parallel water heater 17 flows into the hot water switch valve 141 again. The part of the return pipe 12 that is located between the outlet of the water flow side pipeline 1111 and the hot water switch valve 141 is a first return pipe section 123, a second check valve 1231 is arranged on the first return pipe section 123 for avoiding the hot water discharged from the outlet of the parallel water heater 17 from returning to the first return pipe section 123 in the water flow side pipeline 1111, ensuring that the condenser 111 can be normally used, and the water-cooled refrigerator 11 can normally refrigerate.

When the outlet of the parallel water heater 17 is in communication with the first return pipe segment 123, and thus indirectly with the hot water switching valve 141, through a heater pipe, as shown in fig. 2, the second one-way valve 1231 is located on the first return pipe segment 123 between the outlet of the water flow side pipe 1111 and the heater pipe.

Further, as shown in fig. 2, in one embodiment, a portion of the water return pipe 12 located between the inlet of the water flow side pipeline 1111 and the circulation driving member 121 is a second water return pipe section 126, the second water return pipe section 126 is in cross communication with the water heater cold water pipe 18, a third check valve 19 is disposed on the second water return pipe section 126, and the third check valve 19 is located between the circulation driving member 121 and the water heater cold water pipe 18 and is used for preventing cold water in the water heater cold water pipe 18 from flowing back to the second water return pipe section 126.

The water in the water return pipe 12 can directly flow into the parallel water heater 17, specifically, the water can flow into all or part of the parallel water heater 17, and the cold water is mainly provided by the cold water inlet pipe 13 in the water flow side pipeline 1111 of the condenser 111. Both the water heated by the parallel water heater 17 and the hot water absorbed by the water flow side pipeline 1111 of the condenser 111 flow into the water return pipe 12 and are available for the hot water supply area 14.

Further, as shown in fig. 2, when the second water return pipe segment 126 is provided with the first check valve 122, the first check valve 122 is located between the cold water pipe 18 of the water heater and the condenser 11.

Further, in still another embodiment, as shown in fig. 3, a portion of the return pipe 12 between the outlet of the water flow side pipe 1111 and the hot water switching valve 141 is a first return pipe section 123, and the first return pipe section 123 routes the compressor 112 or the air conditioner condenser 20 of the water-cooled refrigerator 11, further using heat generated from the compressor 112 or the air conditioner condenser 20.
