    FIELD OF THE INVENTION
    [001] The invention relates to intermodal cargo transport that involves the transport of cargo in a container or intermodal vehicle, using multiple modes of transport, such as trains, ships and trucks. In particular, the invention relates to pre-shipment inspection of containers with a climate control system used in intermodal freight transport, where, for example, climate-sensitive cargo is transported. A pre-shipment inspection includes inspection and testing of the container's structural components and its climate control system prior to loading the cargo into the container to ensure that only containers that meet certain quality criteria are used (as evidenced by a satisfactory pre-shipment inspection report), and in particular, that the container has the desired performance for at least one period including the next journey with cargo loaded in the container. BACKGROUND OF THE INVENTION
    [002] The transport and storage of temperature sensitive cargo for periods of time may require a controlled climate in the space where the cargo is loaded. Climate control includes controlling the temperature of the cargo and the humidity of the air in the container to remain within acceptable limits. Temperature control includes bringing the temperature of the load into the acceptable range, through cooling or heating, and maintaining the temperature within that range. Climate control can also include controlling the composition and humidity of the air in the space where the cargo is carried.
    [003] The temperature of the temperature-sensitive load must be kept within predefined acceptable limits. Part of the cargo must be kept frozen, and the temperature of any part of the frozen cargo must be kept below a preset freezing temperature that depends on the cargo, for example, below -18 degrees Celsius (ie, 0.4 degrees Fahrenheit ) or lower, while goods such as fresh fruits and vegetables must be kept chilled, but not frozen, to stay fresh.
    [004] During the operation of a refrigeration system, water vapor will condense in the evaporator and form a layer of ice that will degrade the efficiency of the evaporator and, with it, of the refrigeration system. Accumulated ice is removed through a defrost cycle. Traditionally, defrost cycles are initiated according to a predetermined schedule at time intervals that may depend on the nature of the cargo and the time since loading into the container, or defrosting can be performed on demand based on actual findings.
    [005] Some loads require the relative humidity to be kept within acceptable limits. Some loads are sensitive to high or low temperatures, while others are relatively insensitive to temperature. Examples of such products include electronics and optical products, scientific instruments, machinery and metals such as iron and steel that can corrode if the relative humidity is too high, clothing and other fabrics in which mold growth can be prevented by keeping it low the relative humidity.
    [006] For temperature-sensitive loads, such as chilled and frozen loads, it is vitally important that the load is kept within an acceptable temperature range, otherwise the load could degrade and lose its value.
    [007] Therefore, it is common to perform a pre-shipment inspection, PTI, of the container where the structural and functional components of the container are inspected and tested in order to function correctly for at least one more journey with cargo.
    [008] A container with its cargo is delivered to its destination, where the cargo is removed from the container. The empty container can then be transported to an inspection site, where a PTI is performed on the empty container. Containers that meet PTI's quality criteria are approved for continuous use for a certain period before a new PTI needs to be performed. This approval is documented in a satisfactory PTI report, which most insurers require prior to shipment. Containers that do not meet the quality criteria do not receive a satisfactory PTI report and are not approved for continued use, and therefore necessary steps are taken to restore quality, for example through repairs or adjustments. This procedure is time-consuming. SUMMARY OF THE INVENTION
    [009] Pre-shipment inspection includes inspecting the structural components of the container for integrity and possible mechanical damage, which includes visual inspection.
    [0010] According to the invention, in-service diagnostic testing includes automatically testing the operation of the climate control system at a possibly pre-programmed time which may depend on the period of time since the most recent pre-shipment inspection, or the in-service diagnostic test can be scheduled to be performed during transport from the origin to the destination at an appropriate time before the expected arrival to the destination so that a satisfactory PTI report resulting from the in-service diagnostic test is recent and up to date . The in-service diagnostic test can then advantageously be carried out with cargo in the container.
    [0011] When the in-service diagnostic test is performed, the test results are stored in a controller memory for later recall in the form of a PTI report. In one embodiment of the invention, in-service diagnostic test results are transmitted wirelessly (e.g., by satellite or over a cellular telephone network) by the climate control system controller to a receiver in a central facility operator, where the management and allocation of a large number of containers for transport tasks is carried out. The central facility may be an onshore maintenance and service facility and/or where containers are allocated for specific tasks, or, when containers are on board a ship, an onboard service facility where inspection data from multiple containers they are collected and shipped to a ground facility, or from which part of the repair and maintenance can be carried out on board.
    [0012] At the central facility, therefore, it will be known which containers are approved for additional use and which ones require maintenance and repair. In this way, containers that have not passed the in-service diagnostic test and need maintenance and repair are identified prior to arrival at the destination, making it possible to plan the appropriate action in advance, and once such container arrives at its destination and is emptied, it can be taken out of service.
    [0013] Other aspects of the invention will become apparent from consideration of the detailed description and accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
    [0014] FIG. 1 is a perspective view of a cargo shipping container, and
    [0015] FIG. 2 is a schematic view of a refrigeration system that can be used with the container in FIG. 1. DETAILED DESCRIPTION OF THE INVENTION
    [0016] Before we explain in detail the embodiments of the invention, it should be understood that the invention is not limited, in its application, to the details of construction and the arrangements of the components presented in the description below or illustrated in the drawings below. The invention is susceptible to other modalities and to be practiced or carried out in various ways.
    [0017] FIG. 1 is a perspective view of a container 100 that can be used to transport cargo of various types. Attached to one end of the container is a climate control system 10, such as a refrigeration system that is used to control the climate, including, for example, the temperature and humidity level, of the interior of container 100. 0 container 100 it could alternatively be a trailer, a rail car, a non-hinged truck load space or other storage compartment used for cargo transport.
    [0018] FIG. 2 is a schematic view of refrigeration system 10 which includes a dehumidification system. The illustrated embodiment includes a refrigeration system 10 with a compressor 20 which, in operation, compresses a fluid refrigerant used in the climate control system 10. The hot compressed refrigerant is led from the compressor 20 through conduits 21 and 31 to a condenser. 30, where thermal energy is removed from the refrigerant. The illustrated condenser 30 is fan assisted, and the condensed and cooled refrigerant leaves the condenser 30 through a conduit 32 and enters a receiving tank 33. If additional cooling of the refrigerant is desired, for example, if sufficient cooling with air is not sufficient, an optional 30' water-cooled condenser (illustrated in a box in dashed lines) can be used. From the receiving tank 33 (or, optionally, the water-cooled condenser 30'), the condensed refrigerant is led through a conduit 34 (eg a liquid line) through an oil filter drier 35 to an exchanger of heat economizer 40 and through a conduit 41 and a thermostatic expansion valve 42 to an evaporator 50. The fans 55 circulate air through the evaporator 50 and through the interior of the container 100 in a direction illustrated by the arrows.
    The evaporator 50 has a first part 102 and a second part 104. The evaporator 50 is a tube-fin type heat exchanger. The refrigerant in the first part 102 and the second part 104 arrives at a discharge point 105 where the refrigerant leaves the evaporator 50 and is returned to the compressor 20 via a return conduit 22.
    [0020] The climate control system 10 has a first distributor 51 and a second distributor 52, each of which is connected to receive cold condensed refrigerant from conduit 41 and thermostatic expansion valve 42. The first distributor 51 may also receive the refrigerant through a conduit 56 and feeds the refrigerant to the tubes of the first part 102 of the evaporator 50, and the second distributor 52 feeds the refrigerant to the tubes of the second part 104 of the evaporator 50. The control valves 53 and 54 control the flow of refrigerant to the respective distributors 51 and 52. A conduit 56 connects the output of the second control valve 54 to the inlet of the first distributor 51. Reference numerals 21, 22, 31, 32, 34, 41 and 56 denote conduits for transporting the soda.
    [0021] A controller 110 controls the operation of the climate control system 10. A temperature sensitive element 108 measures the temperature of the interior of the container 100 and relays a signal representing the temperature to the controller 110. An electrical heating element 60 disposed adjacent to evaporator 50 is used for defrosting and heating. A humidity sensor 106 is arranged to detect the relative humidity of the air in the container 100 and issue a corresponding signal to the controller 110 to determine if the relative humidity is within acceptable limits.
    [0022] According to the invention, in-service diagnostic testing includes automatically testing the operation of the climate control system 10 and its individual components at a time that may be pre-programmed and may depend on the period of time since a previous or latest pre-shipment inspection.
    [0023] Each component to be tested in the in-service diagnostic test is tested at a time when the test does not interfere with the normal operation of the climate control system, or when its effect on normal operation is known and can be compensated or neglected.
    [0024] In the in-service diagnostic test according to the invention, the energy consumption of the individual components of the climate control system is determined, preferably in both an enabled state and a disabled state, where the energy consumption is determined is compared with a nominal value. Excessive deviations from a nominal value can indicate component failure and must be handled accordingly.
    [0025] A. In a state of climate control system 10 inactivity, or when no activity is expected, in-service diagnostic testing may include looking at the power consumption of the climate control system as a whole, but also of the individual components of the system. In this state, only controller 110, and possibly some other standby components, are expected to consume power. If the total power consumption is below a predefined threshold, this part of the in-service diagnostic test is passed. On the other hand, if the total power consumption is above the preset threshold, that part of the in-service diagnostic test is not passed and further tests can be started to identify the one or more components consuming more power than expected and acceptable.
    [0026] In an idle state of the climate control system 10, the electrical voltage and frequency of the power supply can be determined, whereby it is possible to determine and record the quality of the power supply.
    [0027] B. Heater 60 is used to defrost the evaporator while non-defrost related components are deactivated and the power consumption of heater 30 is determined and compared to its nominal power consumption value. Possibly, the temperature sensitive element 108 can be used to verify that heat is actually produced as expected. Also here, the electrical voltage and frequency of the power supply can be determined, through which it is possible to determine and record the quality of the power supply.
    [0028] C. The condenser 30 has a motor-driven fan that blows air through the condenser coil to remove heat from the coil. The condenser fan is active when the climate control system is activated, and the power consumption of the condenser fan can be determined at such times. An airflow sensor can also be applied to determine that an airflow is actually generated by the condenser fan. Alternatively, the condenser fan can be activated in an idle state of the climate control system or during defrosting.
    [0029] D. Temperature sensors (not shown) are arranged in connection with the condenser to detect the ambient air temperature and the temperature of the condenser coil. In order to check the (relative) accuracy of these two temperature sensors, the condenser fan motor is activated while the compressor is deactivated, for example during defrosting. This will cause the condenser coil to assume the ambient air temperature, and the readings from the two temperature sensors should therefore be identical or nearly identical. If this is not the case, a corrective measure could be to change one or both of the sensors, or to take the two different readings into account when determining the difference between the two temperatures.
    [0030] E The compressor motor operates on a three-phase electrical power supply. If two phases in the energy fed to the system are interchanged, the motor will rotate in the opposite direction to what is expected. In a simple test as to whether this is the case, the system will interchange two phases. The compressor will present different loads to its motor in the forward (normal) rotation direction and in the reverse rotation direction, and the compressor motor will have different corresponding energy consumptions in the forward and reverse rotation directions. The different three-phase consumptions are connected correctly, and if not, take the appropriate corrective action, such as swapping two phases.
    [0031] F. The climate control system may have pressure sensors to detect the pressure drop across the evaporator 50. A supply pressure sensor detects the refrigerant pressure in the supply conduit between the thermostatic expansion valve 42 and distributors 51 and 52, and a back pressure sensor detects the pressure of refrigerant in the return conduit 22 between the discharge point 105 and the compressor 20. The pressure readings are used to monitor the pressure of the refrigerant in the system, and the difference between supply pressure and back pressure in an equalized state of the refrigerant is an indicator of the flow of refrigerant through the evaporator and a comparison can be made with the expected and accepted values under operating conditions such as ambient temperature , the actual temperature in the container and the setpoint temperature which is the target temperature.
    [0032] G. The climate control system must be able to prevent excessively high refrigerant pressures that could potentially damage the system. The above mentioned supply pressure sensor and other pressure sensors can be used for this purpose. During such a test, the compressor 20 is operated at or near its maximum capacity whereby, in particular, the supply pressure increases until it reaches a maximum threshold pressure level which should not be exceeded during normal operation. It is tested whether, when this threshold pressure level is reached, a safety routine must be activated to deactivate the compressor, whereby the pressure will decrease. It is verified that the pressure actually decreases, and, when it has decreased below a second threshold pressure level, that the compressor will be activated again.
    [0033] H. The economizer heat exchanger 40 is used to increase the cooling capacity of the system, if desired. To do this, a solenoid valve on the output side of the oil filter 35 is activated to drive the refrigerant through a thermostatic expansion valve to the heat exchanger 40. The heat exchanger being active will represent an increased load on the compressor, whereby the power consumption of the compressor will increase. Higher power consumption indicates that the solenoid valve is operating as desired, and vice versa, if the compressor power consumption does not increase accordingly, it indicates that the solenoid valve is not operating as intended.
    [0034] The motors of the fans 55 that circulate air through the evaporator 50 and through the interior of the container 100 are individually tested by activating the fans and determining their energy consumption. The test is carried out at different motor speeds and the corresponding energy consumptions are determined and compared with acceptable values. A deviation from acceptable values indicates malfunction of the corresponding fan motor. An airflow sensor can also be applied to determine that an airflow is actually generated by the evaporator fans 50.
    [0035] Temperature sensors are provided to detect the temperature of the air fed by the evaporator fans 50 to the container, the temperature of the air that is returned from the container and the temperature of the evaporator. One way to verify the accuracy of these sensors is to activate the evaporator fans 50 in a state where there is no other system activity. Thereby, these three temperatures will tend to become equal, and the readings, therefore, must also be equal. Any load other than the frozen load may produce heat, and in such cases, the return air temperature will consequently be higher than the supply air temperature. Deviations from acceptable readings may indicate malfunction of one or more of the temperature sensors.
    [0036] The climate control system will normally have on time periods in which refrigeration is provided and the temperature in the container is decreased, and off time periods in which no refrigeration is provided and the temperature in the container will increase due to a higher ambient temperature (in the case where heating is needed instead of cooling, the situation is reversed). With a given ambient temperature and a given load and a given setpoint temperature for the load, it is possible to calculate, or at least estimate, the energy consumption that is required for a normally operating climate control system to maintain the temperature setpoint temperature with actual room temperature, where the difference between the room temperature and the setpoint temperature is the temperature difference that the climate control system must maintain. The actual durations ta of the activated time periods and the durations tp of the time period between consecutive activations of the climate control system can be determined by simple measurements, and the ta/tp ratio can then be calculated. The ta/tp ratio, also known as the duty cycle, is a number expressing the fraction of the total time the climate control system is activated, that is, where it provides refrigeration, and is an indicator, for example, how close the system is operating to its maximum capacity. Deviations, in particular when greater than expected and acceptable duty cycles are observed, indicate that the cooling capacity of the system is less than expected, and possibly also below an acceptable limit. One reason for the reduction in refrigeration capacity is that the refrigerant is at a low level and needs to be filled.
    [0037] While the container with its cargo is being transported by rail, ship or truck, the controller 110 stores information about the result of the diagnostic test in service in a memory for later retrieval and sends, to a receiver in a central establishment, a wireless message with corresponding information (ie test results) and information identifying the container and climate control system. The message is sent over a wireless connection, such as a satellite connection or a cell phone network or other suitable wireless connection. The determination as to whether the container including its climate control system has passed the test and whether an approval for additional service has been issued can be made by the climate control system controller or at the central facility. If the climate control system has passed and is approved for additional service, a satisfactory PTI report is generated for the climate control system. In addition to a recently performed test, such a determination may also be based on other data, such as the container's history including previous PTI reports of the system and its components, also on experience gained with the other containers or on other parameters.
    [0038] The in-service diagnostic test may be carried out including any of the tests described above individually, or part or all of them in any desired combination, and also additional tests not described here, all carried out under the control of the controller 110. An inspection Pre-shipment traditionally takes place in an empty container at an appropriate time upon arrival at your destination and after your cargo has been unloaded. According to the method of the invention, the in-service diagnostic test (to generate a PTI report) can be initiated by an operator or automatically by the system and the in-service diagnostic test is performed automatically at a time when there is load in the container. .
    [0039] If the in-service diagnostic test is passed, the container and its climate control system are approved for additional use or continued under load for a period until a new in-service diagnostic test needs to be performed, which allows the container and its climate control system to be used for one or more journeys with cargo. New in-service diagnostic tests can be scheduled to be performed in a timely manner before the approval period expires so that the approval period does not expire when the container is being transported with cargo.
