Description

Technical Field

[0001] The utility model relates to the technical field of heat recovery, in particular to a condensed water heat recovery device of a water cooling unit. Background Art

[0002] The heat released by the condenser of the water-cooled unit is usually discharged into the surrounding environment by the cooling tower or cooling fan, which is a huge waste for places that need heat, such as hotels, factories, hospitals, etc., and also brings certain waste heat pollution to the surrounding environment.

[0003] Heat recovery is to recover and reuse the large amount of waste heat discharged to the outside during the operation of the chiller in a certain way as the final heat source or primary heat source for the user. The high-temperature and high-pressure gaseous refrigerant discharged by the compressor first enters the heat recovery device, releases heat to heat domestic water, and then passes through the condenser and expansion valve, absorbs the heat of the cooled medium in the evaporator, becomes a low-temperature and low-pressure gaseous refrigerant, and returns to the compressor.

[0004] However, the condensate heat recovery device of a common water-cooled unit needs to heat domestic water, which causes the temperature of the condensate to continue to rise, reducing the efficiency of the condensate in absorbing the heat of the refrigerant, resulting in a reduction in the cooling effect of the chiller. In view of this, the present application proposes a condensate heat recovery device for a water-cooled unit. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a condensate water heat recovery device for a water-cooled unit, which has the advantages of controlling the temperature of the condensate water, etc., and solves the problem that the temperature of the condensate water will continue to rise due to the need to heat domestic water, which makes the efficiency of the condensate water absorbing the heat of the refrigerant reduced, resulting in a reduction in the cooling effect of the chiller.

[0006] In order to achieve the above-mentioned purposes of controlling the temperature of condensed water, etc., the utility model provides the following technical solutions: a condensed water heat recovery device of a water-cooled unit, comprising a cooling box, a hot water tank is fixedly installed on one side of the cooling box, a temperature sensor is fixedly installed on the inner wall of the hot water tank, a control panel and a controller are fixedly installed on one side of the hot water tank, a water filling pipe is fixedly installed on the top of the hot water tank, a water filling valve is fixedly installed on the surface of the water filling pipe, a water outlet pipe is fixedly installed on the bottom of the hot water tank, and a water outlet valve is fixedly installed on the surface of the water outlet pipe.

[0007] Furthermore, the controller is electrically connected to the temperature sensor, the control panel, the water filling valve and the water outlet valve.

[0008] Furthermore, a condensation water pipe is fixedly installed on the top of the hot water tank, one end of the condensation water pipe is fixedly connected to the top of the cooling box, and the condensation water pipe connects the cooling box with the hot water tank.

[0009] Furthermore, a return pipe is fixedly installed at the bottom of the hot water tank, one end of the return pipe is fixedly connected to the bottom of the cooling box, and the return pipe connects the cooling box with the hot water tank.

[0010] Furthermore, an acceleration pump is fixedly installed on the top of the hot water tank, and the acceleration pump is arranged in the middle of the condensation water pipe.

[0011] Furthermore, a heat dissipation pipe is wound from bottom to top inside the cooling box, a refrigerant input pipe is fixedly installed at the input end of the heat dissipation pipe, and a refrigerant output pipe is fixedly installed at the output end of the heat dissipation pipe.

[0012] Furthermore, a hot water insulation layer is fixedly installed on the inner wall of the hot water tank, and a heat dissipation insulation layer is fixedly installed on the inner wall of the cooling tank.

[0013] Compared with the prior art, the utility model provides a condensate heat recovery device for a water-cooling unit, which has the following beneficial effects:

[0014] The condensing water heat recovery device of the water-cooling unit is configured with a temperature sensor inside the hot water tank, and the temperature range of the water outlet is input through the control panel. When the water temperature in the hot water tank is too high, the controller opens the water filling valve and the water outlet valve, so that the hot water in the hot water tank flows out quickly, and cold water is added to mix until the water temperature drops. This solves the problem that the temperature of the condensing water will continue to rise due to the need to heat domestic water, which reduces the efficiency of the condensing water absorbing the heat of the refrigerant and causes the cooling effect of the chiller to decrease.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1: Please refer to Figure 1-3 A condensate water heat recovery device of a water-cooled unit comprises a cooling box 1, a hot water tank 2 is fixedly mounted on one side of the cooling box 1, a temperature sensor 3 is fixedly mounted on the inner wall of the hot water tank 2, a control panel 4 and a controller 5 are fixedly mounted on one side of the hot water tank 2, a water adding pipe 6 is fixedly mounted on the top of the hot water tank 2, a water adding valve 7 is fixedly mounted on the surface of the water adding pipe 6, a water outlet pipe 8 is fixedly mounted on the bottom of the hot water tank 2, and a water outlet valve 9 is fixedly mounted on the surface of the water outlet pipe 8.

[0021] The controller 5 is electrically connected to the temperature sensor 3, the control panel 4, the water adding valve 7 and the water outlet valve 9. The temperature of the water in the hot water tank 2 is detected by the temperature sensor 3, and a water temperature range is set on the control panel 4. When the temperature sensor 3 detects that the temperature of the water in the hot water tank 2 exceeds the maximum water temperature, the controller 5 opens the water adding valve 7 and the water outlet valve 9, adds cold water, and discharges hot water, so as to reduce the temperature of the water in the hot water tank 2 and improve the heat dissipation efficiency.

[0022] At the same time, a condensation water pipe 10 is fixedly installed on the top of the hot water tank 2 , one end of the condensation water pipe 10 is fixedly connected to the top of the cooling box 1 , and the condensation water pipe 10 connects the cooling box 1 with the hot water tank 2 .

[0023] A return pipe 11 is fixedly installed at the bottom of the hot water tank 2 , one end of the return pipe 11 is fixedly connected to the bottom of the cooling tank 1 , and the return pipe 11 connects the cooling tank 1 with the hot water tank 2 .

[0024] Secondly, an acceleration pump 12 is fixedly installed on the top of the hot water tank 2, and the acceleration pump 12 is arranged in the middle of the condensation water pipe 10. The acceleration pump 12 inputs the water in the hot water tank 2 into the cooling box 1 through the condensation water pipe 10, and the water enters the cooling box 1 and then returns to the hot water tank 2 through the return pipe 11 at the bottom.

[0025] Meanwhile, a heat dissipation pipe 13 is wound from bottom to top inside the cooling box 1, a refrigerant input pipe 14 is fixedly installed at the input end of the heat dissipation pipe 13, and a refrigerant output pipe 15 is fixedly installed at the output end of the heat dissipation pipe 13. Cold water contacts the heat dissipation pipe 13 in the cooling box 1 and absorbs the heat of the heat dissipation pipe 13.

[0026] Embodiment 2: Based on Embodiment 1, a hot water insulation layer 16 is fixedly installed on the inner wall of the hot water tank 2. The hot water insulation layer 16 reduces the loss of water temperature in the hot water tank 2, thereby reducing the temperature loss of the heated water and increasing the efficiency of heat recovery. A heat dissipation insulation layer 17 is fixedly installed on the inner wall of the cooling box 1. The heat dissipation insulation layer 17 reduces the loss of water temperature in the cooling box 1, thereby reducing the loss of heat absorbed by the water and increasing the efficiency of heat recovery.

[0027] When this embodiment is in use, the controller 5 opens the water filling valve 7 and closes the water outlet valve 9, and cold water enters the hot water tank 2 from the water filling pipe 6. At the same time, the acceleration pump 12 is turned on to allow water to enter the cooling box 1 through the condensation water pipe 10. After the cooling box 1 is full of water, the water filling valve 7 is closed, and the water in the cooling box 1 absorbs the heat of the heat dissipation pipe 13, and then flows back to the hot water tank 2 through the return pipe 11, so as to realize the circulation of water. A suitable temperature range is input through the control panel 4. When the water temperature in the hot water tank 2 is higher than the maximum value, the temperature sensor 3 detects the water temperature, and then transmits the water temperature signal to the controller 5. The controller 5 opens the water filling valve 7 and the water outlet valve 9 to release the hot water, and adds cold water to lower the water temperature and improve the heat dissipation efficiency. After the water temperature drops to the set temperature value, the water filling valve 7 and the water outlet valve 9 are closed to continue to absorb heat.
