Description

Technical Field

[0001] The utility model relates to the technical field of heat pump exhaust, in particular to a device for alleviating the cold island effect of a heat pump. Background Art

[0002] The exhaust vent of the heat pump is set at the top. After the cold air is discharged from the exhaust vent, it will sink to the surrounding of the heat pump under the action of gravity due to its high density. This phenomenon may cause several problems.

[0003] First, cold air gathers around the heat pump, significantly lowering the ambient temperature. This localized low temperature affects the heat exchange efficiency of the heat pump's evaporator. The evaporator absorbs heat from the environment to complete the heat exchange process. If the ambient temperature is too low, the evaporator's efficiency will decrease, reducing the overall performance of the heat pump.

[0004] Secondly, continued cold air deposition can cause a cold air "loop" to form around the heat pump. This cold air circulation not only affects the heat pump's own operating efficiency but can also affect other surrounding equipment or the working environment. For example, in certain industrial applications or residential environments, this cold air deposition can cause abnormal temperatures in a local area, affecting the normal operation of other equipment or human comfort.

[0056] Since the exhaust vent of the heat pump is set at the top, and the cold air is discharged from the exhaust vent, it settles to the surrounding of the heat pump under the action of gravity, which will significantly reduce the temperature of the surrounding environment, affect the heat exchange efficiency of the heat pump evaporator, and reduce the overall performance of the heat pump; and, continuous cold air sedimentation may cause a cold air "circulation" to form around the heat pump. This cold air circulation not only affects the operating efficiency of the heat pump itself, but may also have an impact on other surrounding equipment or the working environment.

[0057] In view of this, if Figure 1 and Figure 2 As shown, this solution provides a device for alleviating the cold island effect of a heat pump, including an exhaust assembly;

[0058] The exhaust assembly includes a constricted duct 100 and an exhaust fan 200;

[0059] The exhaust fan 200 is provided at the exhaust port 300 of the heat pump 700;

[0060] The shrinkage duct 100 is connected to the exhaust port 300;

[0061] The end of the shrinking duct 100 connected to the exhaust port 300 gradually shrinks inwards toward the end away from the exhaust port 300;

[0062] The air outlet 110 of the tapered duct 100 forms an angle of 45° with the horizontal plane.

[0063] When the cold air is accelerated and extracted by the exhaust fan 200, it first passes through the wide end of the tapered duct 100. During the flow of the cold air, the inner diameter of the tapered duct 100 continues to decrease, which accelerates the flow speed of the cold air and discharges it from the tapered duct 100 to a farther distance. In addition, the air outlet 110 has an angle of 45° with the horizontal plane, so that the cold air can settle in an area far away from the heat pump 700 without affecting the heat exchange efficiency of the heat pump 700 evaporator, thereby improving the overall performance of the heat pump 700.

[0064] Regarding the shape and structure of the conduit 100 Figure 1 As shown:

[0065] The conduit 100 includes a first pipe section 120 and a second pipe section 130;

[0066] The first pipe section 120 is in a bent cylindrical shape, one end of which is connected to the exhaust port 300 and the other end of which is connected to the second pipe section 130;

[0067] There is an angle of 45° between the end of the first pipe section 120 connected to the exhaust port 300 and the end of the first pipe section 120 connected to the second pipe section 130;

[0068] The second pipe section 130 is tapered;

[0069] The second pipe section 130 gradually contracts inward from the end connected to the first pipe section 120 to the end away from the first pipe section 120;

[0070] There is a smooth transition between the first pipe section 120 and the second pipe section 130;

[0071] The inner wall of the conduit 100 is provided with a low friction coating.

[0072] More preferably, Figure 1 As shown in , the tapered duct consists of two parts, wherein the first pipe section is a bent pipe, the bending surface of the first pipe section adopts a smooth transition, the second pipe section is connected to the side of the first pipe section away from the heat pump 700, the transition at the connection is smooth and the inner wall of the tapered duct 100 has a low-friction coating, which further reduces the friction resistance of the cold air and increases the wind speed of the cold air.

[0073] like Figure 2 As shown, it also includes an adjustment component 400;

[0074] The adjustment assembly 400 includes a motor, a driving tooth 410 and a driven tooth 420;

[0075] The driving gear 410 is socketed with the output end of the motor;

[0076] The driving teeth 410 are meshed and connected with the driven teeth 420;

[0077] The driven teeth 420 are provided on the inner wall of the conduit 100 ;

[0078] The motor controls the shrinking conduit 100 to rotate along the axis of the driven tooth 420 .

[0079] Specifically, the inner diameter of one end of the tapered duct 100 connected to the exhaust outlet 300 is much larger than the outer diameter of the exhaust outlet 300. The motor is arranged in the space outside the exhaust outlet 300. The output end of the motor is perpendicular to the horizontal plane and can be connected to the driving tooth 410 by plugging or meshing to provide power output for the driving tooth 410.

[0080] The driven teeth 420 are distributed along the entire inner wall of the shrinking conduit 100 and can be arranged at the bottom of the shrinking conduit or other suitable installation positions.

[0081] When set at the bottom, the motor can be set upside down so that the output end of the motor is set downward; when set in the middle position, the motor can be set forward to save installation space to the greatest extent.

[0082] like Figure 1 As shown, a wind speed sensor 500 is also included;

[0083] The wind speed sensor 500 is disposed on the outer wall of the air outlet 110;

[0084] The wind speed sensor 500 is electrically connected to the motor.

[0085] Specifically, the wind speed measurement direction of the wind speed sensor 500 is the same as that of the air outlet 110. It can measure the wind speed blowing toward the air outlet 110, that is, the headwind speed of the cold air discharged by the exhaust fan 200. When the headwind speed is too large, the wind speed sensor 500 will output a signal to the motor and control the motor to drive the tapered duct 100 to rotate, so as to adjust the outlet direction of the cold air and avoid being affected by the headwind.

[0086] More preferably, it further includes a wind power generation module 600;

[0087] The wind power generation module 600 is disposed at the air outlet 110;

[0088] The blades of the wind power generation module 600 are facing the air outlet 110; the wind power generation module 600 is electrically connected to the heat pump 700, and the cold air discharged by the exhaust fan 200 can drive the blades of the wind power generation module 600 to rotate and generate electricity. The recovered electricity can supplement the power of the motor or the heat pump 700.

[0089] This solution has at least the following beneficial effects:

[0090] This solution significantly improves the overall performance of the heat pump by improving the exhaust design of the heat pump. Specifically, a tapered duct 100 and an exhaust fan 200 are provided at the exhaust port of the heat pump so that the exhausted cold air can settle in an area away from the heat pump 700, avoiding the accumulation of cold air around the heat pump 700, thereby preventing the cold island effect from affecting the heat exchange efficiency of the heat pump evaporator. The design of the tapered duct 100 accelerates the cold air during its flow, and the air outlet 110 forms a 45° angle with the horizontal plane, allowing the cold air to be more effectively away from the heat pump 700. This solution not only improves the performance of the heat pump 700, but also reduces the impact of cold air on the surrounding environment and equipment.

[0091] In addition, this solution incorporates an adjustment assembly 400, which uses a motor to drive the rotation of the tapered duct 100, further optimizing the airflow direction and avoiding the effects of headwinds. The installation of a wind speed sensor 500 enables the system to monitor headwind speed in real time and promptly adjust the airflow direction of the tapered duct 100 to ensure the stability and effectiveness of cold air discharge. The introduction of a wind power generation module 600 utilizes the discharged cold air to drive blades to generate electricity, providing additional power to the system and improving energy efficiency.
