The cab refrigeration system and the commercial vehicle of the present application will be described below with reference to the accompanying drawings.
FIG. 1 is a schematic view of a cab according to an embodiment of the present disclosure; fig. 2 is a schematic structural diagram of a refrigerating system of a cab in an embodiment of the present application. For convenience of description, only the structures related to the present application are shown in the drawings.
Referring to fig. 2, a refrigeration system 200 of a cab 100 according to at least one embodiment of the present disclosure includes an original vehicle air conditioner, an engine, a parking air conditioner 220, a whole vehicle battery, and a heat insulation curtain 230. The refrigeration system 200 is used for cooling the cab 100, providing a comfortable riding environment for drivers and passengers, reducing fatigue strength of the drivers and improving driving safety.
The original air conditioner is driven by an engine. Specifically, the compressor of the original air conditioner is driven by the automobile engine, the refrigerating performance is greatly influenced by the operation of the engine, and the temperature, the wind speed and the wind direction can be controlled by the function keys on the control panel in the cab 100 of the driver.
The parking hole air conditioner is driven by the whole vehicle storage battery. Specifically, parking air conditioner 220 further includes a compressor assembly 223, a condenser assembly 224, and an evaporator assembly 225. The compressor assembly 223 and the condenser assembly 224 are disposed outside the cab 100, and the evaporator assembly 225 is disposed within the cab 100. The compressor assembly 223, the condenser assembly 224, and the evaporator assembly 225 are in communication in sequence to form a refrigerant circuit.
More specifically, compressor assembly 223 includes an electric air conditioner compressor, condenser assembly 224 includes a condenser and a condenser electronic fan, and evaporator assembly 225 includes an evaporator and an evaporation fan. Further, the parking air conditioner 220 further includes an expansion valve.
Specifically, in practical application, after the electric air conditioner compressor works, the refrigerant is compressed into high-temperature high-pressure gas, then the high-temperature high-pressure gas enters the condenser, the condenser electronic fan dissipates heat of the condenser, the refrigerant is changed into high-temperature medium-pressure liquid refrigerant, the liquid refrigerant is throttled by the expansion valve to be changed into low-temperature low-pressure vaporific refrigerant, then the low-temperature low-pressure vaporific refrigerant passes through the evaporator, the evaporation fan blows air through the evaporator, heat exchange is carried out on air and the refrigerant in the evaporator, the air temperature is reduced, and cold air is formed. And the vaporific refrigerant absorbs heat to become low-temperature low-pressure gaseous refrigerant and then returns to the compressor to complete a refrigeration cycle.
Further, referring to fig. 1, the cab 100 includes an upper sleeper 111 and a lower sleeper 112 disposed at an upper and lower interval of the sleeper region 110. Further, referring to fig. 2, an upper air outlet 141 and a lower air outlet 142 are respectively formed on the side walls 130 of the cab 100 corresponding to the upper sleeper 111 and the lower sleeper 112. Wherein, the upper air outlet 141 and the lower air outlet 142 are both communicated with the parking air conditioner 220.
In particular, in practical application, cold air formed by the parking air conditioner 220 can be accurately sent to the upper sleeper 111 and the lower sleeper 112 through the upper air outlet 141 and the lower air outlet 142 respectively, so that power consumption of the parking air conditioner 220 can be reduced, and comfort of personnel on the upper sleeper 111 and the lower sleeper 112 can be improved.
Further, the side wall 130 includes an outer side wall 131 and an inner side wall 132 spaced from the outer side wall 131. The upper air outlet 141 and the lower air outlet 142 are both disposed on the inner side wall 132. The parking air conditioner 220 includes an air conditioning duct 221, and the air conditioning duct 221 is disposed between the outer sidewall 131 and the inner sidewall 132 and can communicate with the upper air outlet 141 and the lower air outlet 142. In this way, the influence of the wiring of the parking air conditioner 220 on the structure of the cab 100 can be reduced.
Further, a control air door 222 is disposed in the air conditioning pipeline 221, and the control air door 222 is rotatably connected to the air conditioning pipeline 221. The rotation path of the control damper 222 has a position capable of independently conducting one of the air conditioning duct 221 and the upper air outlet 141 and the lower air outlet 142, and simultaneously conducting both.
In particular, in practical application, when only the upper sleeper 111 has a rest person, the control air door 222 can be rotated to a position for independently conducting the air conditioning pipeline 221 and the upper air outlet 141, so that the cold air generated by the parking air conditioner 220 is directly sent to the upper sleeper 111. Thus, not only can the power consumption of the parking air conditioner 220 be reduced, but also the comfort of the driver and passengers can be improved.
When only the lower sleeper 112 has rest personnel, the control air door 222 can be rotated to a position for independently conducting the air conditioning pipeline 221 and the lower air outlet 142, so that cold air generated by the parking air conditioner 220 is directly sent to the lower sleeper 112. Thus, not only can the power consumption of the parking air conditioner 220 be reduced, but also the comfort of the driver and passengers can be improved.
When the rest personnel are on the upper sleeper 111 and the lower sleeper 112, the control air door 222 can be rotated to the position for simultaneously conducting the air conditioning pipeline 221, the upper air outlet 141 and the lower air outlet 142, so that cold air generated by the parking air conditioner 220 can be simultaneously sent to the upper sleeper 111 area and the lower sleeper 112 area. Thus, not only can the power consumption of the parking air conditioner 220 be reduced, but also the comfort of the driver and passengers can be improved.
Further, the refrigeration system 200 further includes a controller 250, and the controller 250 is communicatively connected to the parking air conditioner 220.
Specifically, in practical applications, the driver and passenger can operate the parking air conditioner 220 through the parking air conditioner 220 controller 250, including but not limited to starting, closing the parking air conditioner 220, adjusting the air-out gear of the parking air conditioner 220, setting the target temperature of the sleeper region 110, etc.
Further, referring to fig. 2, the controller 250 is disposed on the top cover of the cab 100 corresponding to the lower sleeper 112. In particular, in practical use, the controller 250 is disposed on the top cover of the cab 100 corresponding to the lower sleeper 112, so that the convenience of the driver in operating the parking air conditioner 220 can be improved. It is to be understood that the foregoing is illustrative only and is not to be construed as limiting the present application.
In some embodiments, referring to FIG. 1, the refrigeration system 200 further includes an insulating curtain 230. A thermal curtain 230 is disposed within cab 100, thermal curtain 230 having an extended state and a retracted state.
In some embodiments, thermal shield 230 may be manually switched state. Specifically, thermal shield curtain 230 may be manually pulled by a driver to effect expansion or contraction of thermal shield curtain 230, thereby completing switching of thermal shield curtain 230 between the expanded state and the contracted state.
In other embodiments, thermal shield 230 may automatically switch states. Specifically, a heat shield curtain 230 switch is provided within cab 100, and heat shield curtain 230 switch is communicatively coupled to a drive member that is drivingly coupled to heat shield curtain 230. A driver and a passenger can control the expansion and contraction of the heat shielding curtain 230 through the opening and closing of the heat shielding curtain 230, thereby realizing the switching of the heat shielding curtain 230 between the expanded state and the contracted state.
Further, a driver's seat, an instrument desk, a subsidiary driver's seat and a sleeper are provided in the cab 100 of the commercial vehicle. The heat insulation curtain 230 is arranged between the driver seat, the instrument desk and the auxiliary driver seat and the sleeper, and is controlled to separate the regions where the driver seat, the instrument desk and the auxiliary driver seat and the sleeper are respectively located.
Specifically, when the heat shielding curtain 230 is in the extended state, the cab 100 can be partitioned into the driving area 120 and the sleeper area 110, which are independent of each other, and the driver's seat, the instrument desk, the sub-driver's seat, and the sleeper are in the partitioned state. At this time, the movement of the air flow in the cab 100 is restricted, and the movement of the air flow between the riding area 120 and the sleeper area 110 is blocked. When heat shield curtain 230 is in the retracted state, airflow within cab 100 is free to flow.
When the refrigerating system 200 is used for refrigerating, when the heat insulation curtain 230 is in a contracted state, the engine is controlled to drive the original vehicle air conditioner to refrigerate the cab 100, and the parking air conditioner 220 is controlled to be closed; when the heat insulation curtain 230 is in an extended state, the heat insulation curtain 230 divides the cab 100 into the sleeper region 110 and the driving region 120, the whole car battery controlled driving parking air conditioner 220 refrigerates the sleeper region 110, and the original car air conditioner is controlled to be closed.
Specifically, the original air conditioner is started to cool the interior of the cab 100, and the engine is turned off after the temperature of the cab 100 is lowered. Therefore, the refrigerating noise of the air conditioner is reduced, and the comfort of drivers and passengers is improved. Then, the cab 100 is partitioned into the sleeper region 110 and the driving region 120 by the heat insulation curtain 230, the parking air conditioner 220 is turned on, and the parking air conditioner 220 cools only the sleeper region 110. Therefore, the cooling area of the parking air conditioner 220 is reduced, the refrigerating load of the air conditioner is reduced, the purpose of saving the energy consumption of the air conditioner is achieved, and the duration of the parking air conditioner 220 can be prolonged.
In some embodiments, thermal curtain 230 comprises a polyester thermal curtain 230. The terylene heat insulation curtain 230 has good heat insulation and shading effects, and is healthy and environment-friendly. It is to be understood that the foregoing is illustrative only and is not to be construed as limiting the present application. For example, a fibrous thermal insulation curtain 230 is also included, and the fibrous thermal insulation curtain 230 also has a good light-shielding and thermal insulation effect.
Further, the refrigeration system 200 further includes a window shade 240 provided at the front window of the cab 100, the window shade 240 having a light reflecting state capable of covering the front window and a light entering state exposing the front window. When the reflective curtain 240 is in a reflective state, the original vehicle air conditioner or the parking air conditioner 220 is controlled to be started; when the light reflecting curtain 240 is in the light entering state, the original car air conditioner and the parking air conditioner 220 are controlled to be turned off.
Specifically, when the intensity of the solar radiation is high, the temperature in the cab 100 can be reduced by adjusting the light reflecting curtain 240 to cover the front window of the cab 100, so as to reduce the sunlight entering the cab 100. In this way, after the air conditioner is turned on, the time for the temperature in the cab 100 to drop to the target temperature can be significantly shortened, thereby greatly reducing the energy consumption of the air conditioner. When the intensity of the solar radiation is not great, and in order not to hinder driving, the window shade 240 may be adjusted to expose the front window. Thus, lighting and driving of the commercial vehicle are not affected.
More specifically, under daytime conditions, if the ambient temperature is high (> 38 ℃) and the solar radiation intensity is high, and the temperature in the cab 100 is high, the original vehicle air conditioner is started to cool down, and meanwhile, the reflective curtain 240 on the front air window is pulled up to reduce the solar radiation heat load of the cab 100, and when the temperature of the cab 100 is reduced (feel cool), the engine can be turned off. The park air conditioner 220 is then activated to cool while the heat shield curtain 230 is pulled to separate the sleeper region 110 from the front riding region 120, and the rider rests on the sleeper region 110.
In addition, if the ambient temperature is low (< 38 ℃) and the solar radiation is weak during daytime or the night working condition, the parking air conditioner 220 is directly started to refrigerate, and simultaneously the reflective curtain 240 on the front windshield and the heat insulation curtain 230 of the sleeper region 110 are pulled, so that the driver and the passenger rest in the sleeper region 110.
In some embodiments, referring to fig. 1, the cab 100 includes an upper sleeper 111 and a lower sleeper 112 disposed at upper and lower intervals in the sleeper region 110. Further, referring to fig. 2, an upper air outlet 141 and a lower air outlet 142 are respectively formed on the side walls 130 of the cab 100 corresponding to the upper sleeper 111 and the lower sleeper 112. Wherein, the upper air outlet 141 and the lower air outlet 142 are both communicated with the parking air conditioner 220.
As the same concept of the present application, there is also provided a commercial vehicle characterized by comprising the cooling system of the cab 100 described above. The commercial vehicle with the cooling system has long endurance time and high driving comfort.
In the cooling system of the cab 100 and the commercial vehicle, when the heat insulation curtain 230 is in a contracted state, the engine is controlled to drive the original vehicle air conditioner to refrigerate the cab 100, and the parking air conditioner 220 is controlled to be closed; when the heat insulation curtain 230 is in an extended state, the heat insulation curtain 230 divides the cab 100 into the sleeper region 110 and the driving region 120, the whole car battery controlled driving parking air conditioner 220 refrigerates the sleeper region 110, and the original car air conditioner is controlled to be closed. Specifically, the original air conditioner is started to cool the interior of the cab 100, and the engine is turned off after the temperature of the cab 100 is lowered. Therefore, the refrigerating noise of the air conditioner is reduced, and the comfort of drivers and passengers is improved. Then, the cab 100 is partitioned into the sleeper region 110 and the driving region 120 by the heat insulation curtain 230, the parking air conditioner 220 is turned on, and the parking air conditioner 220 cools only the sleeper region 110. Therefore, the cooling area of the parking air conditioner 220 is reduced, the refrigerating load of the air conditioner is reduced, the purpose of saving the energy consumption of the air conditioner is achieved, and the duration of the parking air conditioner 220 can be prolonged.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
