Description

Technical Field

[0001] The present invention relates to the technical field of parking air conditioners, and in particular to an outdoor unit of a parking air conditioner, a control method for the outdoor unit of the parking air conditioner, a parking air conditioner having the outdoor unit of the parking air conditioner, and a vehicle having the outdoor unit of the parking air conditioner. Background Art

[0002] With the economic development and the improvement of the quality of life, people's requirements for comfort are getting higher and higher. More and more drivers of large vehicles have a demand for parking air conditioners, and parking air conditioners are gradually occupying an increasing market share.

[0003] The outdoor unit of the parking air conditioner is placed at the outer top of the vehicle cab, and the indoor unit is placed inside the vehicle cab. The air inlet of the outdoor unit is opened on the windward side of the casing. The condenser is arranged inside the casing. The windward side of the casing is arranged towards the forward direction of the vehicle, so that the windward side of the condenser is consistent with the forward direction of the vehicle. During the forward movement of the vehicle, due to the relative movement, the air flow can enter the casing from the air inlet and enter the condenser from the windward side of the condenser, thereby dissipating heat from the condenser.

[0004] However, there is an air flow dispersion phenomenon when the flowing air enters the casing from the air inlet of the outdoor unit of the parking air conditioner. Only a small part of the flowing air entering the casing can enter the condenser from the windward side of the condenser for heat dissipation, resulting in poor heat dissipation effect, unable to guarantee the heat dissipation effect of the condenser, causing the system pressure to rise, the refrigeration effect to deteriorate or high-pressure alarm, and causing damage to the compressor, etc.

[0005] In addition, the control accuracy of the outdoor fan of the current outdoor unit of the parking air conditioner is relatively low. As long as the parking air conditioner is turned on and running, regardless of whether the vehicle is in a driving state or a parking state, the running speed of the outdoor fan remains unchanged. However, when the vehicle is in a driving state, the air flow rate is fast, and the heat dissipation effect of the condenser is better than when the vehicle is in a parking state. And the running speed of the outdoor fan remains unchanged regardless of whether the vehicle is in a driving state or a parking state, resulting in energy consumption waste and increasing the fuel consumption of the vehicle. Summary of the Invention

[0006] In order to achieve the first object of the present invention, the present invention provides an outdoor unit of a parking air conditioner with better heat dissipation effect of the condenser and better heat exchange effect.

[0007] In order to achieve the second object of the present invention, the present invention provides a control method for the above-mentioned outdoor unit of the parking air conditioner, which saves energy while meeting the heat exchange effect.

[0008] In order to achieve the third object of the present invention, the present invention provides a parking air conditioner having the above-mentioned outdoor unit of the parking air conditioner.

[0009] To achieve the fourth object of the present invention, the present invention provides a vehicle having the above-mentioned parking air conditioner outdoor unit.

[0010] To achieve the first object of the present invention, the present invention provides a parking air conditioner outdoor unit, including a housing, a condenser and an outdoor fan. The housing is used to be arranged at the outer top of the vehicle. The condenser and the outdoor fan are respectively arranged in the housing. The windward side of the housing faces the forward direction of the vehicle and is provided with an air inlet, and the housing is also provided with an air outlet. The outdoor fan is arranged at the air outlet. The housing is provided with a baffle. The baffle is located below the condenser in the direction perpendicular to the forward direction, and the free end of the baffle away from the condenser extends obliquely downward toward the windward side of the housing relative to the forward direction, and the included angle between the baffle and the forward direction is an acute angle.

[0011] As can be seen from the above solution, the parking air conditioner outdoor unit of the present invention is arranged at the outer top of the vehicle. When the parking air conditioner outdoor unit operates for refrigeration, the outdoor fan is turned on. Under the action of the outdoor fan, external air enters the housing from the air inlet of the housing to dissipate heat from the condenser, and then discharges the hot air carrying the heat of the condenser from the air outlet of the housing. Since the housing of the parking air conditioner outdoor unit of the present invention is provided with a baffle, the baffle is located below the condenser in the direction perpendicular to the forward direction, and the free end of the baffle away from the condenser extends obliquely downward toward the windward side of the housing relative to the forward direction, and the included angle between the baffle and the forward direction is an acute angle. Along with the external air entering the housing from the air inlet of the housing to dissipate heat from the condenser, some of the dispersed airflows in the housing are diverted and concentrated to flow toward the condenser for heat dissipation under the diversion of the baffle, thereby improving the heat dissipation effect on the condenser, making the heat dissipation effect of the condenser better, and improving the heat exchange effect of the condenser, making the heat exchange of the condenser more sufficient and the heat exchange effect of the condenser better.

[0012] A further solution is that the air outlet is located above the condenser in the direction perpendicular to the forward direction, and the outdoor fan is located above the condenser in the direction perpendicular to the forward direction.

[0013] A further solution is that the included angle between the baffle and the forward direction is between 20° and 60°.

[0014] A further solution is that the parking air conditioner outdoor unit further includes an air duct. The first end of the air duct covers the condenser, the second end of the air duct extends to the air outlet, the outdoor fan is arranged in the second end of the air duct, and an air guiding plate is arranged on the side of the first end of the air duct close to the air inlet. An air guiding channel is formed between the air guiding plate and the base of the housing, and the air guiding channel is communicated between the air inlet and the air duct.

[0015] A further solution is that the air guiding channel gradually narrows from the air inlet toward the condenser.

[0016] A further solution is that the parking air conditioner outdoor unit also includes an electrical box, which is located inside the casing and arranged on the leeward side of the casing in the forward direction, and the electrical box is located outside the air duct, and the first port of the air duct has an air inlet between the side away from the air inlet and the base, and the base has an exhaust outlet on the leeward side of the casing in the forward direction.

[0017] A further solution is that a first air guide plate is provided at the air inlet of the base, and a free end of the first air guide plate away from the base is extended downwardly toward the windward side of the casing and is inclined relative to the forward direction, and the angle between the first air guide plate and the forward direction is an acute angle; and / or, a second air guide plate is provided at the air outlet of the base, and a free end of the second air guide plate away from the base is extended downwardly toward the leeward side of the casing and is inclined relative to the forward direction, and the angle between the second air guide plate and the forward direction is an acute angle.

[0018] In order to achieve the second purpose of the present invention, the present invention provides a control method for a parking air-conditioning outdoor unit, the parking air-conditioning outdoor unit is the above-mentioned parking air-conditioning outdoor unit, and the control method includes: obtaining the ambient temperature T1 outside the vehicle and the current temperature T2 of the condenser, the current temperature T2 is greater than or equal to the ambient temperature T1; and adjusting the operating speed of the outdoor fan according to the difference between the current temperature T2 and the ambient temperature T1.

[0019] It can be seen from the above scheme that while the parking air-conditioning outdoor unit of the present invention is structurally provided with a baffle to achieve better heat dissipation effect and heat exchange effect of the condenser, the control method of the parking air-conditioning outdoor unit of the present invention adjusts the operating speed of the outdoor fan by controlling the difference between the current temperature T2 of the condenser and the ambient temperature T1 outside the vehicle, that is, the difference between the current temperature T2 of the condenser and the ambient temperature T1 outside the vehicle can reflect the temperature of the condenser in the current working state and the temperature that can be reduced by physical adjustment, so that the operating speed of the outdoor fan can be adjusted more accurately, saving energy while satisfying the heat exchange effect.

[0020] A further solution is to obtain the ambient temperature T1 and the current temperature T2 after the outdoor unit of the parking air conditioner is turned on and operates for the first preset time t1 for cooling.

[0021] A further solution is that after each control to adjust the running speed of the outdoor fan is completed, the outdoor unit of the parking air conditioner runs for a second preset time t2, and then the ambient temperature T1 and the current temperature T2 are re-acquired.

[0022] A further solution is that when the difference between the current temperature T2 and the ambient temperature T1 is within a preset temperature range, the operating speed of the outdoor fan is controlled to maintain the current operating speed.

[0023] A further solution is that when the difference between the current temperature T2 and the ambient temperature T1 is less than the preset temperature range, the operating speed of the outdoor fan is controlled to decrease to the first operating speed at the first preset speed.

[0024] A further solution is that when the difference between the current temperature T2 and the ambient temperature T1 is greater than the preset temperature range, the operating speed of the outdoor fan is controlled to increase to the second operating speed at the second preset speed.

[0025] To achieve the third object of the present invention, the present invention provides a parking air conditioner, including a parking air conditioner outdoor unit, and the parking air conditioner outdoor unit is the above-mentioned parking air conditioner outdoor unit.

[0026] To achieve the fourth object of the present invention, the present invention provides a vehicle, including a parking air conditioner outdoor unit, and the parking air conditioner outdoor unit is the above-mentioned parking air conditioner outdoor unit. Description of the Drawings

[0032] Embodiment of the parking air conditioner outdoor unit:

[0033] Referring to Figures 1 to 3 , this embodiment discloses a parking air conditioner outdoor unit 10, including a housing 11, a condenser 13 and an outdoor fan 12. The housing 11 is used to be arranged at the outer top of the vehicle. The condenser 13 and the outdoor fan 12 are respectively arranged in the housing 11. The windward side of the housing 11 faces the forward direction 20 of the vehicle and is provided with an air inlet 111, and the housing 11 is also provided with an air outlet 112. The outdoor fan 12 is arranged at the air outlet 112. Moreover, in this embodiment, the housing 11 is provided with a baffle 1131. The baffle 1131 is located below the condenser 13 in the direction perpendicular to the forward direction 20, and the free end of the baffle 1131 away from the condenser 13 extends obliquely downward towards the windward side of the housing 11 relative to the forward direction 20. The included angle θ between the baffle 1131 and the forward direction 20 is an acute angle.

[0034] In this embodiment, the outdoor unit 10 of the parking air conditioner is arranged at the external top of the vehicle. When the outdoor unit 10 of the parking air conditioner operates for refrigeration, the outdoor fan 12 is turned on. Under the action of the outdoor fan 12, the external air enters the casing 11 from the air inlet 111 of the casing 11 to dissipate heat from the condenser 13, and then discharges the hot air carrying away the heat of the condenser 13 from the air outlet 112 of the casing 11. Since the baffle 1131 is arranged on the casing 11 of the outdoor unit 10 of the parking air conditioner in this embodiment, the baffle 1131 is located below the condenser 13 in the vertical forward direction 20, and the free end of the baffle 1131 away from the condenser 13 extends obliquely downward toward the windward side of the casing 11 relative to the forward direction 20. The included angle θ between the baffle 1131 and the forward direction 20 is an acute angle. Along with the external air entering the casing 11 from the air inlet 111 of the casing 11 to dissipate heat from the condenser 13, some of the dispersed airflows in the casing 11 are diverted and concentrated to flow toward the condenser 13 for heat dissipation under the diversion of the baffle 1131, thereby improving the heat dissipation effect on the condenser 13, making the heat dissipation effect of the condenser 13 better, and improving the heat exchange effect of the condenser 13, making the heat exchange of the condenser 13 more sufficient and the heat exchange effect of the condenser 13 better.

[0035] Specifically, the air outlet 112 of the casing 11 in this embodiment is located above the condenser 13 in the vertical forward direction 20, and the outdoor fan 12 is located above the condenser 13 in the vertical forward direction 20. And, the included angle θ between the baffle 1131 and the forward direction 20 in this embodiment is between 20° and 60°. Preferably, the included angle θ between the baffle 1131 and the forward direction 20 in this embodiment is between 30° and 40°, which can enable more dispersed airflows in the casing 11 to be diverted and concentrated to flow toward the condenser 13 for heat dissipation, further improving the heat dissipation effect on the condenser 13.

[0036] In order to further improve the heat dissipation effect on the condenser 13, the outdoor unit 10 of the parking air conditioner in this embodiment further includes an air duct 15. The first end opening of the air duct 15 covers the condenser 13, the second port of the air duct 15 extends to the air outlet 112, the outdoor fan 12 is arranged in the second port of the air duct 15, an air guiding plate 151 is arranged on the side of the first port of the air duct 15 close to the air inlet 111, and an air guiding channel 152 is formed between the air guiding plate 151 and the base 113 of the casing 11. The air guiding channel 152 is communicated between the air inlet 111 and the air duct 15. Specifically, the air guiding channel 152 gradually narrows from the air inlet 111 toward the condenser 13, which can pressurize the airflows entering the first port of the air duct 15 from the air inlet 111, thereby increasing the flow rate of the airflows flowing toward the condenser 13 for heat dissipation, and further having a better heat dissipation effect on the condenser 13.

[0037] The outdoor unit 10 of the parking air conditioner in this embodiment further includes an electrical box 14. The electrical box 14 is located inside the housing 11 and is arranged near the leeward side of the housing 11 in the forward direction 20, and the electrical box 14 is located outside the air duct 15. There is an air inlet 1132 between the first port of the air duct 15, which is far from the air inlet 111, and the base 113. The base 113 is provided with an air outlet 1133 near the leeward side of the housing 11 in the forward direction 20. Therefore, a part of the air flow entering the air duct 15 can enter from the air inlet 1132 to dissipate heat from the electrical box 14, and the heated air flow is discharged from the air outlet 1133, improving the heat dissipation effect of the electrical box 14. Specifically, in this embodiment, the base 113 is provided with a first air deflector 1134 at the air inlet 1132. The free end of the first air deflector 1134 away from the base 113 extends obliquely downward toward the windward side of the housing 11 relative to the forward direction 20. The included angle β between the first air deflector 1134 and the forward direction 20 is an acute angle. The first air deflector 1134 can guide more air flow in the air duct 15 to smoothly enter the air inlet 1132 to dissipate heat from the electrical box 14. And in this embodiment, the base 113 is provided with a second air deflector 1135 at the air outlet 1133. The free end of the second air deflector 1135 away from the base 113 extends obliquely downward toward the leeward side of the housing 11 relative to the forward direction 20. The included angle γ between the second air deflector 1135 and the forward direction 20 is an acute angle. The second air deflector 1135 can guide the heated air flow to be smoothly discharged. Among them, in this embodiment, the included angle β between the first air deflector 1134 and the forward direction 20 is between 20° and 60°, and the included angle γ between the second air deflector 1135 and the forward direction 20 is between 20° and 60°. Preferably, in this embodiment, the included angle β between the first air deflector 1134 and the forward direction 20 is between 30° and 40°, and the included angle γ between the second air deflector 1135 and the forward direction 20 is between 30° and 40°.

[0038] Embodiment of the control method of the outdoor unit of the parking air conditioner:

[0039] The control method of the outdoor unit of the parking air conditioner in this embodiment is the control method of the above-mentioned outdoor unit 10 of the parking air conditioner. Refer to Figure 3 , the specific implementation steps of the control method of the outdoor unit of the parking air conditioner in this embodiment are as follows.

[0040] First, step S1 is executed. After the outdoor unit 10 of the parking air conditioner starts to operate in the cooling mode for the first preset time t1, step S2 is executed. The ambient temperature T1 outside the vehicle and the current temperature T2 of the condenser 13 are obtained. The ambient temperature T1 outside the vehicle is obtained through a temperature sensor, and the temperature sensor can be set at any position on the vehicle or the outdoor unit 10 of the parking air conditioner, as long as the ambient temperature T1 outside the vehicle can be accurately obtained. The ambient temperature T1 is the ambient temperature outside the vehicle that is not affected by the outdoor unit 10 of the parking air conditioner. The current temperature T2 of the condenser 13 is obtained through a temperature sensor set on the condenser 13. Among them, during the operation of the outdoor unit 10 of the parking air conditioner in the cooling mode, the current temperature T2 of the condenser 13 is always greater than or equal to the ambient temperature T1 outside the vehicle.

[0041] Since the current temperature of the condenser 13 fluctuates in the initial stage of the operation of the outdoor unit 10 of the parking air conditioner in the cooling mode, there will be a certain deviation in obtaining the current temperature of the condenser 13 in the initial stage of the operation in the cooling mode. To ensure the accuracy of adjusting the running speed of the outdoor fan 12 according to the difference between the current temperature T2 of the condenser 13 and the ambient temperature T1 outside the vehicle in the subsequent steps, in the control method of the outdoor unit of the parking air conditioner in this embodiment, after the outdoor unit 10 of the parking air conditioner starts to operate in the cooling mode, the timing module is first called to start timing after the central control module recognizes that the outdoor unit 10 of the parking air conditioner starts to operate in the cooling mode. When the outdoor unit 10 of the parking air conditioner operates for the first preset time t1, the data acquisition module acquires the first set of the ambient temperature T1 outside the vehicle and the current temperature T2 of the condenser 13 during the operation of the outdoor unit 10 of the parking air conditioner in the cooling mode, and sends this set of parameters to the central control module of the outdoor unit 10 of the parking air conditioner. Specifically, the first preset time t1 in this embodiment is between 5 min and 30 min.

[0042] After obtaining the ambient temperature T1 outside the vehicle and the current temperature T2 of the condenser 13, the running speed of the outdoor fan 12 is adjusted according to the difference between the current temperature T2 of the condenser 13 and the ambient temperature T1 outside the vehicle, as follows.

[0043] Execute step S3 to determine whether the difference between the current temperature T2 of the condenser 13 and the ambient temperature T1 outside the vehicle is within a preset temperature range. If so, it indicates that the condenser 13 is in a normal heat exchange state, which also means that the vehicle is in a constant-speed driving state and the heat exchange is normal during constant-speed driving. Then execute step S4 to control the operating speed of the outdoor fan 12 to maintain the current operating speed. If not, then execute step S5. Among them, the preset temperature range in this embodiment is 2°C - 5°C. Thus, when the difference between the current temperature T2 of the condenser 13 and the ambient temperature T1 outside the vehicle is within the preset temperature range of 2°C - 5°C, it indicates that the condenser 13 is in a normal heat exchange state, and step S4 is executed to control the operating speed of the outdoor fan 12 to maintain the current operating speed.

[0044] When the difference between the current temperature T2 of the condenser 13 and the ambient temperature T1 outside the vehicle does not meet the requirement of being within the preset temperature range, execute step S5 to determine whether the difference between the current temperature T2 of the condenser 13 and the ambient temperature T1 outside the vehicle is less than the preset temperature range. If so, it indicates that the condenser 13 is in a state of over-sufficient heat exchange, which also means that the vehicle is in a high-speed driving state and the heat exchange is more sufficient during high-speed driving. Then execute step S6 to control the operating speed of the outdoor fan 12 to decrease to the first operating speed at the first preset speed. If not, then execute step S7. Among them, the first preset speed in this embodiment is 50 r / min. Thus, when the difference between the current temperature T2 of the condenser 13 and the ambient temperature T1 outside the vehicle is less than the preset temperature range of 2°C - 5°C, that is, less than 2°C, it indicates that the condenser 13 is in a state of over-sufficient heat exchange, and step S6 is executed to control the operating speed of the outdoor fan 12 to decrease to the first operating speed at the first preset speed of 50 r / min.

[0045] When the difference between the current temperature T2 of the condenser 13 and the ambient temperature T1 outside the vehicle does not meet the requirement of being less than the preset temperature range, execute step S7 to determine whether the difference between the current temperature T2 of the condenser 13 and the ambient temperature T1 outside the vehicle is greater than the preset temperature range. If so, it indicates that the condenser 13 is in a state of poor heat exchange, which also means that the vehicle is in a parked state and the heat exchange is poor during parking. Then execute step S8 to control the operating speed of the outdoor fan 12 to increase to the second operating speed at the second preset speed. Among them, the second preset speed in this embodiment is 100 r / min. Thus, when the difference between the current temperature T2 of the condenser 13 and the ambient temperature T1 outside the vehicle is greater than the preset temperature range of 2°C - 5°C, that is, greater than 5°C, it indicates that the condenser 13 is in a state of poor heat exchange, and step S8 is executed to control the operating speed of the outdoor fan 12 to increase to the second operating speed at the second preset speed of 100 r / min, and the speed adjustment range will also become larger.

[0046] After each adjustment of the operating speed of the outdoor fan 12 is completed, that is, after one of the adjustment controls in step S4, step S6, and step S8 is executed, step S9 is executed, and the outdoor unit 10 of the parking air conditioner operates for a second preset time t2. In this embodiment, the value range of the second preset time t2 for the outdoor unit 10 of the parking air conditioner is between 0 and 6 minutes. Preferably, the second preset time t2 in this embodiment is 3 minutes.

[0047] When the outdoor unit 10 of the parking air conditioner operates for the second preset time t2 with the parameters after one of the adjustment controls in step S4, step S6, and step S8 is executed, step S2 is executed, and the ambient temperature T1 outside the vehicle and the current temperature T2 of the condenser 13 are acquired again, so as to repeatedly cycle the control steps of adjusting the operating speed of the outdoor fan 12 according to the difference between the current temperature T2 of the condenser 13 and the ambient temperature T1 outside the vehicle.

[0048] While the baffle 1131 is provided on the structure of the outdoor unit 10 of the parking air conditioner to achieve better heat dissipation and heat exchange effects of the condenser 13, the control method of the outdoor unit of the parking air conditioner in this embodiment adjusts the operating speed of the outdoor fan 12 according to the difference between the current temperature T2 of the condenser 13 and the ambient temperature T1 outside the vehicle. That is, the difference between the current temperature T2 of the condenser 13 and the ambient temperature T1 outside the vehicle can reflect the temperature of the condenser 13 under the current working state and the temperature that can be reduced through physical adjustment, so as to more accurately adjust the operating speed of the outdoor fan 12, save energy while meeting the heat exchange effect.

[0049] The above embodiments are only preferred examples of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features, and principles of the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
