Description

Eco-friendly cooling system of transport equipment for frozen and cold storage}

The present invention relates to a cooling system for transportation equipment (vehicles, construction machinery, ships, agricultural machinery, etc.) for freezing and refrigeration.

Conventional refrigerators obtain the power source of the mounted refrigerator from the engine, and in the case of large refrigerators, a separate auxiliary engine is used.

Another conventional refrigerator is equipped with a cooling plate (PCM module) in which PCM (Phase Change Material) of an appropriate temperature range is enclosed in a plate-shaped or specific-shaped container to maintain the temperature inside the refrigerator. Therefore, a conventional refrigerator can accumulate cold heat through electricity during late-night hours and maintain the internal temperature at a low temperature using a cooling plate at night without operating the refrigerator.

PCM is a material that absorbs surrounding heat and maintains the surrounding temperature at a low temperature for a long time in the process of turning into a solid state through cooling and then slowly changing into a liquid.

In particular, refrigeration vehicles using only PCM cooling plates do not use engine power, so their energy efficiency is very high compared to vehicles operating with engine-driven refrigerators. However, due to an increase in the weight of the PCM cooling plate containing the cooling material, the weight of the vehicle increases, and thus the fuel efficiency of the vehicle decreases. In addition, the cooling system using a PCM cooling plate has the disadvantage that it is difficult to continuously maintain a constant temperature for a long period of time and the variation in the cooling temperature maintenance range is large.

The eco-friendly cooling system (hereinafter simply referred to as the cooling system) of transportation equipment for refrigeration and refrigeration (a general term for vehicles, construction machinery, ships, and agricultural machinery) according to the present invention is a cargo compartment with a roof or lid equipped with refrigeration and refrigeration facilities. Applies to transportation equipment equipped with (200). In particular, the present invention uses a cooling-only battery 110 as power for the electric compressor 115, and can use a cooling plate (referred to as a side cooling module) together with the cooling-only battery 110. In the following description, the transportation device may be any one of vehicles, construction machinery, ships, and agricultural machinery.

Problems with conventional cooling systems are as follows.

First, in a typical engine-based refrigerated truck, the driver does not operate the engine-driven refrigerator normally to save on fuel costs, or the refrigerator does not perform properly in hot weather.

Second, the cold storage cooling plate type refrigeration truck has the disadvantage of lowering the efficiency of use because the vehicle cannot be driven during the cooling storage time (about 10 hours). In order to sufficiently lower the internal temperature, it is necessary to use a cold storage cooling plate with a lower freezing point. In this case, the time for cooling becomes longer and its practicality is not recognized. In addition, since a large amount of cooling plates must be used to achieve cooling performance, the weight of the entire vehicle increases, worsening driving fuel efficiency.

The features of the present invention are as follows.

First, the present invention can maintain the set temperature using cold air accumulated in the cooling storage module 140 in normal cases such as short-distance and long-distance transportation, low-speed driving in the city, and stopping for rest, and uses the cooling-only battery 110 as power. The set temperature can be maintained by operating the electric compressor 115. Therefore, according to the present invention, the set temperature can be maintained precisely. Therefore, the freshness of transported products can be guaranteed.

Second, excess cold heat, excluding the cold heat required for the set temperature, can be recycled by accumulating it again on the cold storage cooling plate of the cooling storage module 140. Therefore, the present invention can help users reduce fuel costs by increasing the efficiency of energy use and protect the environment by reducing exhaust gases.

Third, the present invention can ensure the freshness of transported products by maintaining the set temperature of the freezer room at a constant level in any case. Therefore, the present invention can be applied to various low-temperature logistics demand areas such as the agricultural and fisheries industry, food processing industry, restaurant chain industry, courier transportation industry, and convenience stores, and in particular, it can be applied to cold chains such as vaccine transportation.

Fourth, the present invention can be applied to refrigerated top trucks of special purpose vehicles using internal combustion engine trucks or electric electric vehicle trucks, and thus provides an environmentally friendly and efficient refrigeration system.

The structural features of the present invention are described as follows.

It may include a determination unit that transmits data to be displayed.

Cooling transport equipment (vehicles, construction machinery, ships, agricultural machinery), generally called refrigerated trucks or frozen trucks, is equipped with a cargo compartment 200 equipped with a roof or lid, which is a dedicated space for cooling, in addition to the driver's cabin, and has a separate compartment-type space. It is prepared.

The space must be equipped with an optimized cooling function for the storage and transportation of agricultural, livestock, and marine products or logistics that must maintain freshness.

The cooling system according to the present invention cools the room by operating the electric compressor 115 with a cooling-only battery 110 storing electric energy, and at the same time uses the remaining cooling heat source as a cooling plate (cooling storage module) mounted in the cargo compartment ( 140) is cooled.

When the electric energy used in the operation of the electric compressor 115 in the cooling-only battery 110 is exhausted, the cooling-only battery 110 is charged using external AC power 111 or direct current power for business use. At this time, in order to keep the cargo compartment cool, the electric compressor 115 is operated at the same time as the dedicated battery is charged to maintain a constant set temperature, thereby maintaining the freshness of the transportation logistics.

Therefore, the cooling system according to the present invention operates the electric compressor 115 to cool the cooling plate (cooling storage module) 140 for a certain period of time, and the heat loss of the cooling plate (cooling storage module) 140 is lost during driving or stopping. In order to compensate for the wasted cooling performance, the rotational speed of the electric compressor 115 is operated with a constant or speed-changing operation, so that the initial cooled storage temperature can be continuously maintained.

In addition, the present invention can efficiently manage and maintain the temperature of the vehicle loading compartment by minimizing the range of change in maintained temperature.

In addition, when external AC power (111) for business use is connected or when cooling is needed, the cooling system can be remotely operated and stopped anytime, anywhere through a dedicated application on a smartphone, and at the same time, the internal cooling temperature of the room can be checked. You can.

In the present invention, when the cooling plate (cold storage module) 140 is used for a long time and the temperature rises, the cooling-only battery 110 is driven to operate the electric compressor 115 to replenish the lost cold air heat source.

In addition, the present invention can maintain cooling of the cargo compartment 200 for a certain period of time by using the cold air of the cooled cooling plate (cooling storage module) 140 even when the electric compressor 115 malfunctions, thereby preventing corruption of storage logistics and Deterioration of freshness can be prevented.

For the functions and purposes described above, the cooling system according to the present invention includes an electric compressor 115 that compresses gas, a cooling-only battery 110 that supplies power required for the electric compressor 115, and the electric compressor. A condenser (120) that condenses and liquefies the high-temperature, high-pressure refrigerant sent from (115). When the liquid compressed by the condenser (120) evaporates and becomes gas, it absorbs heat from the surroundings and rapidly lowers the surrounding temperature to generate cold air. It includes an evaporator 130, a cooling storage module 140 provided with cooling plates that are cooled using cold air generated by the evaporator 130, and a control unit 150 for controlling the operation of the cooling-only battery 110. .

First, the electric compressor 115 performs the function of converting high temperature and high pressure gas into high pressure liquid. The electric compressor 115 may be driven by electric energy supplied from the cooling-only battery 110.

Next, the cooling-only battery 110 drives the electric compressor 115. The cooling-only battery 110 can store direct current voltage electric energy supplied from an alternating current voltage conversion charging device (OBC-On board charger) mounted on the control unit 150.

Next, the condenser 120 performs the function of condensing and liquefying the high-temperature, high-pressure refrigerant sent from the electric compressor 115.

Next, the control unit 150 converts the external commercial AC power 111 into direct current voltage and uses an AC voltage conversion charging device (OBC-On board charger) to charge the cooling-only battery 110, and the cooling-only battery 110. A DC voltage converter (LDC-Low Voltage Converter) is used to receive electrical energy from electricity and convert it into electricity that is convenient to use as general electricity for transportation equipment (vehicles, construction machinery, ships, agricultural machinery). Each device converts direct current voltage electrical energy into electricity. An electric power distribution unit (PDU) for distributing air conditioning, a cooling control unit (RCU-Refrigeration Control Unit) for integrated control of the speed of the electric compressor by detecting the indoor temperature, and monitoring the cooling temperature control status and smart It may include a telematics and monitoring control unit (TMU-Telematics & Monitoring Unit) that transmits monitoring result data to a phone app or a remote central center through a wireless network so that it can be managed.

When the temperature of the cargo compartment 200 increases due to the cooling module 140 being used for a long time while the electric compressor 115 is not driven, the control unit 150 drives the cooling-only battery 110 to operate the electric compressor. By operating (115), lost cold air can be replenished.

The control unit 150 drives the electric compressor 115 when the external commercial AC power 111 is connected and communicates with a battery management system (BMS) attached to the cooling-only battery 110. By driving the electric compressor 115, the amount of power remaining can be charged to the dedicated battery 110 through the AC voltage conversion charging device (OBC-On board charger).

The battery management system (BMS-Battery Management System) measures the voltage of the cooling-only battery 110, a measuring unit for measuring the state of charge of the cooling-only battery 110, and the measured voltage of the cooling-only battery. It may include an analysis unit that compares and analyzes a preset voltage value, and a determination unit that determines whether there is an abnormality in the cooling-only battery and transmits data to display the abnormality.

Next, the evaporator 130 performs the function of generating cold air by evaporating the liquid compressed by the electric compressor 115.

That is, the evaporator performs the function of absorbing heat from the surroundings when the liquid compressed by the condenser 120 evaporates and becomes gas and rapidly lowering the surrounding temperature to generate cold air.

The evaporator 130 may be equipped with a fan capable of diffusing cold air. The fan may also be mounted on the cooling module 140.

Lastly, the cooling storage module 140 includes cooling plates that are cooled using cold air generated by the evaporator 130.

That is, the cooling module 140 includes cooling plates in which PCM (Phase Change Material) of an appropriate temperature range is enclosed in a plate-shaped or specific-shaped container to maintain the temperature of the cargo compartment 200.

PCM is a material that absorbs surrounding heat and maintains the surrounding temperature at a low temperature for a long time in the process of turning into a solid state through cooling and then slowly changing into a liquid.

Figures 5 and 6 are further illustrations of an eco-friendly cooling system for transportation equipment for freezing and refrigeration according to the present invention, and Figure 7 shows an evaporator applied to an eco-friendly cooling system for transportation equipment for freezing and refrigeration according to the present invention. This is an example diagram showing the connection relationship between and auxiliary evaporator.

In the cooling system according to the present invention, as shown in FIG. 5, the interior space of the cargo compartment 200 is divided into N spaces, and each of the N spaces is provided with an auxiliary evaporator 130a, and the A temperature sensor is provided in each of the N spaces, and the control unit 150 can individually control the auxiliary evaporators 130a using the temperatures detected by the temperature sensors. N is a natural number. For example, the cargo compartment 200 shown in FIG. 5 is divided into eight spaces, and each of the eight spaces is provided with an auxiliary evaporator 130a. Therefore, in the example shown in Figure 5, N may be 8. In the following descriptions, the cargo compartment 200 may be provided with at least one auxiliary evaporator 130a and at least one temperature sensor.

The N spaces are not divided by separate partitions, etc., and can be arbitrarily divided by the user. For example, if the cargo compartment 200 is equipped with N auxiliary evaporators 130a, an area equipped with one auxiliary evaporator 130a may become one space. That is, the N spaces can be set in various ways depending on the positions of the N auxiliary evaporators 130a.

Additionally, N spaces may be divided according to the locations where temperature sensors are provided. That is, a temperature sensor may be provided in each of the N spaces, and therefore, the number of temperature sensors may be N.

However, the N spaces may be arbitrarily divided regardless of the number of auxiliary evaporators 130a and temperature sensors. For example, one temperature sensor may be provided in any one of the N spaces, and the auxiliary evaporator 130a may be moved to various positions within at least two of the N spaces. As another example, one auxiliary evaporator (130a) and at least two temperature sensors may be provided in any one of the N spaces, and one auxiliary evaporator (130a) may be provided with at least two temperature sensors. It can also be moved to various locations within one space.

To elaborate, the N spaces refer to virtual spaces divided by (X, Y, Z) coordinates, and can be divided in various ways.

That is, if the cargo compartment 200 is wide, the temperature in the area closer to the evaporator 130 is lower and the cargo is frozen, and the temperature in the area farther from the evaporator 130 is higher, so the cargo is refrigerated. . To prevent this, the present invention divides the space of the cargo compartment 200 into several small basic embodiment units, so that cooling can be managed and maintained more delicately and uniformly.

For example, when items that are sensitive to temperature control, such as drugs or injections, need to be cooled, the cargo compartment 200 may be divided into N spaces, for example, 5 to 10 spaces. In this case, the control unit 150 can collect the temperature of each space using a temperature sensor and individually control the auxiliary evaporators 130a. In this case, an auxiliary cooling-only battery may be provided for each auxiliary evaporator 130a, and the auxiliary cooling-only batteries may be individually driven by the control unit 150.

That is, the control unit 150 can control each auxiliary cooling-only battery by detecting the voltage, current, and power of each auxiliary cooling-only battery. In this case, the control unit 150 may provide sensing information collected from the temperature sensor, auxiliary evaporators 130a, and auxiliary cooling-only batteries to the user using a mobile phone app, etc.

In addition, in the cooling system according to the present invention, as shown in FIG. 6, the cargo compartment 200 is divided into N spaces, the N spaces are provided with auxiliary evaporators 130a, and the N spaces are provided with auxiliary evaporators 130a. The spaces are provided with rails 131 that can move the auxiliary evaporators 130a, and the auxiliary evaporators 130a are mounted on moving parts 132 that can move along the rails 131. The control unit 150 can individually move the moving units 132 using the temperatures detected by the temperature sensors. In this case, the rail 131 and the moving part 132 may constitute an auxiliary evaporator moving part. That is, the auxiliary evaporator moving part includes a rail 131 provided in the interior space of the cargo compartment and a moving part 132 that moves along the rail, and the auxiliary evaporator 130a can be mounted on the moving part. there is.

Figure 6 shows a cargo compartment 200 equipped with four auxiliary evaporators 130a. Accordingly, as described above, the cargo compartment 200 may be divided into four spaces, and in this case, N may be 4.

However, for example, the auxiliary evaporator 130a may move through two spaces along the rail 131, and in this case, a temperature sensor may be provided in each of the two spaces. That is, when the rails 131 along which the auxiliary evaporator 130a moves in the cargo compartment 200 shown in FIG. 6 are provided in two spaces, the cargo compartment 200 shown in FIG. 6 has four auxiliary evaporators 130a. ) are provided, so the cargo compartment 200 shown in FIG. 6 can be divided into a total of eight spaces. In this case, N may be 8, and a temperature sensor may be provided in each of the eight spaces.

In this case, each of the auxiliary evaporators 130a may be mechanically connected to the condenser 120 and the electric compressor 115 using a pressure-resistant corrugated pipe 139, as shown in FIG. 7. When each of the auxiliary evaporators 130a moves, the corrugated pipe 139 through which the refrigerant passes may expand, contract, or bend at various angles. That is, the corrugated pipe 139 can be bent in the X-axis, Y-axis, and Z-axis directions, and can be configured to have an adjustable length. Accordingly, the auxiliary evaporator (130a) can be moved to various positions by the corrugated pipe (139). Here, the X-axis, Y-axis and Z-axis are arranged perpendicular to each other.

In this case, two corrugated pipes 139 may be connected to each of the auxiliary evaporators 130a for the introduction and withdrawal of refrigerant. For example, one corrugated pipe 139 may be connected to the condenser 120, and another corrugated pipe 139 may be connected to the electric compressor 115.

At least one temperature sensor may be provided in each of the N spaces.

That is, the control unit 150 can detect the temperature of each of the N spaces, and can sense the temperature for each location in any one of the N spaces.

If the control unit 150 determines that operation of the auxiliary evaporator 130a is necessary as a result of temperature detection, it may move the auxiliary evaporator 130a to the corresponding location.

In this case, as described above, each of the N spaces may mean a space in which one auxiliary evaporator (130a) is moved, a space in which one temperature sensor is provided, and at least two It may also mean a space equipped with two temperature sensors.

In particular, each of the moving units 132 may rotate the auxiliary evaporator 130a to the corresponding space where the temperature is to be adjusted under the control of the control unit 150.

Accordingly, cold air can be delivered intensively to the space, and accordingly, the space can be cooled quickly.

That is, according to the present invention, since the auxiliary evaporator can be moved directly to the corresponding space, compared to placing the auxiliary evaporator in each space, equipment costs can be reduced and cooling management can be performed quickly and efficiently.

To explain further, the auxiliary evaporator 130a is connected to the condenser 120, and when the liquid compressed by the condenser evaporates and becomes gas, it absorbs heat from the surroundings and rapidly lowers the surrounding temperature to produce cold air. can occur.

In addition, the auxiliary evaporator 130a includes another electric compressor that compresses gas and another condenser that condenses and liquefies the high-temperature, high-pressure refrigerant sent from the other electric compressor, and the liquid compressed by the other condenser evaporates. When it becomes a gas, it can absorb heat from the surroundings and rapidly lower the surrounding temperature, generating cold air.

The rail 131 and the moving part 132 described above may constitute the auxiliary evaporator moving part. Below, various types of auxiliary evaporator moving parts that can move the auxiliary evaporator 130a will be described.

In this case, the cargo compartment 200 may be divided into N spaces set by the user, and a temperature sensor may be provided in each of the N spaces.

For example, when the cargo compartment 200 is divided into four spaces and the temperature detected by the temperature sensor provided in the first space among the four spaces rises above the preset temperature, the control unit 150 1 Information related to space coordinates (X, Y, Z) is transmitted to the drive control unit 318.

The drive control unit 318 can control the Y-axis drive unit 314, the X-axis drive unit 313a, and the Z-axis drive unit using the received coordinates.

That is, the length of the X-axis moving part is increased or decreased by the . To this end, the .

As the Y-axis moving unit 314a rotates by the Y-axis driving unit 314 driven under the control of the driving control unit 318, the auxiliary evaporator 130a may rotate to a position corresponding to the Y coordinate. For example, the rotating sphere 321 is wrapped in the cover 322 so as not to be separated from it. In this case, the cover is provided with an opening that exposes the rotating sphere, and the Y-axis moving part 314a can be in close contact with the rotating sphere 321 through the opening.

As the Z-axis moving unit 315 moves up and down under the control of the Z-axis driving unit, the auxiliary evaporator 130a may be moved to a position corresponding to the Y coordinate and Z coordinate. In this case, the Z-axis moving unit 315 may actually move in an inclined form on the bottom surface of the cargo compartment 200.
