N \Melbourme\Caks\Patcnt\71000-71999\P71996 AU\Specis\P71996 AU GH Speci as flled.doc 3/05/07 -7- FIG. 4 is a diagram schematically showing a controlling circuit of a cooling device for a reefer container according to a third embodiment of the invention.
e¢3 DETAILED DESCRIPTION OF THE INVENTION First Embodiment: 00 In the following, the embodiments of the cooling device and the controlling method thereof for a reefer container according (1 to the invention are described referring to FIGs. 2 to 4. In Saddition, the cooling device and the controlling method thereof (1 10 can be applied to refrigerated lorry, but here only the description for the reefer container is given below by way of example.
The controlling circuit of the cooling device for the reefer container according to the first embodiment of the invention is shown in FIG. 2. As shown in FIG. 2, the controlling circuit of the cooling device comprises a compressor relay 1, a condenser fan relay 2, an evaporator fan relay 3, a controller 4, a vacuum pressure switch 5 and a pressure switch 7. The controller 4 can control operating states of the compressor relay 1, the condenser fan relay 2 and the evaporator fan relay 3. The vacuum pressure switch 5 is disposed inside the container for controlling the pressure switch 7 to turn on or off according to the air pressure inside the container. In this embodiment, the pressure switch 7 and the compressor relay 1 connected in series, are then connected to the condenser fan relay 2 and the evaporator fan relay 3 in parallel.
An action value for the vacuum pressure switch 5, e.g. 300mm 400mm water column, is preset according to the air pressure inside the container to be controlled (this value will be referred as preset pressure below). When the air pressure inside the container drops to the preset pressure, the vacuum pressure switch 5 controls the pressure switch 7 to turn off.
N.\Mclboumc\Cases\Patenm\7 1000.71999\P7 1996 AL\Specis\P71996AU GH Speci as fileddoc 3/05/07 -8- At this time, the compressor relay 1 is disconnected, and the compressor is caused to stop operating. When the air pressure inside the container rises higher than the preset pressure, the vacuum pressure switch 5 controls the pressure switch 7 to turn on. At this time, the controller 4 controls the compressor relay 1 to turn on, and the compressor begins 00 operation. Thereby it is ensured that the air pressure inside the container is not lower than the preset pressure so as to CI ensure safety of the container body.
To further control the air pressure inside the container, CI the controlling circuit of the cooling device may be provided with a time delay relay 6 therein. The time delay relay 6 is controlled by the vacuum pressure switch 5, and can delay the pressure switch 7 to turn on. The time delay relay 6 is connected in parallel to the pressure switch 7 and the compressor relay 1 connected in series.
When the air pressure inside the container drops to the preset pressure, the vacuum pressure switch 5 controls a contact of the time delay relay 6 to disconnect. When the air pressure inside the container rises higher than the preset pressure, the vacuum pressure switch 5 controls the contact of the time delay relay 6 to connect so that the time delay relay 6 is energized, and the time delay relay 6 delays the pressure switch 7 to turn on, that is, makes the pressure switch 7 turn on after a period of time has elapsed. Therefore, the cooling system will stop operating for a period of time after the air pressure inside the container drops to the preset pressure. Thereby such a risk is prevented that the container body is damaged due to the temperature inside the container dropping and the air pressure inside the container rapidly dropping in the case that the cooling system continuously operates.
Furthermore, in the case that a time delay relay is provided, the pressure switch can be replaced by another contact of the N \Melboum\Cases\Ptent\71000-71999\P7)996 AL\Specis\P71996.AU GH Spcmi as filedmdc 3/05/07 -9time delay relay.
The vacuum pressure switch 5 can be replaced by a common pressure sensor in combination with a controlling device. In operating state, the pressure sensor detects the air pressure inside the container and transmits information of the air pressure inside the container to the controlling device. When 00 the air pressure inside the container drops to the preset pressure or rises higher than it, the controlling device sends CI control signals respectively to the pressure switch 7 and the ]0 time delay relay 6 for controlling them.
CI Second Embodiment: As shown in FIG. 3, the second embodiment is almost the same as the first embodiment except that: the pressure switch 7 and the compressor relay 1 connected in series are connected to the evaporator fan relay 3 in parallel, and the condenser fan relay 2 is connected to the compressor relay 1 in parallel.
In this way, when the air pressure inside the container drops to the preset pressure, the vacuum pressure switch 5 controls the pressure switch 7 to turn off. At this time, the compressor relay 1 and condenser fan relay 2 are disconnected, and the compressor and the condenser fan are caused to stop operating.
When the air pressure inside the container rises higher than the preset pressure, the vacuum pressure switch 5 controls the pressure switch 7 to turn on. At this time, the controller 4 controls the compressor relay 1 and the condenser fan relay 2 to turn on, and the compressor and the condenser fan begin operation. Thereby it is ensured that the air pressure inside the container is not lower than the preset pressure, so as to ensure safety of the container body.
Third Embodiment: As shown in FIG. 4, the third embodiment is almost the same as the first embodiment except that: the compressor relay 1, the condenser fan relay 2 and the evaporator fan relay 3 N \Nielboune\Cases\Paten\71000-71999\P7 1996 ASpcil\P7996 AU GH Spemi as filed dmc 3/05/07 connected in parallel, are then connected to the pressure switch 7 in series.
In this way, when the air pressure inside the container drops to the preset pressure, the vacuum pressure switch 5 controls the pressure switch 7 to turn off. At this time, the compressor relay 1, the condenser fan relay 2 and the evaporator fan relay 00 3 are disconnected, and the compressor, the condenser fan and the evaporator fan are caused to stop operating. When the air (Ni pressure inside the container rises higher than the preset pressure, the vacuum pressure switch 5 controls the pressure (1 switch 7 to turn on. At this time, the controller 4 controls the compressor relay i, the condenser fan relay 2 and the evaporator fan relay 3 to turn on, and the compressor, the condenser fan and the evaporator fan begin operation. Thereby it is ensured that the air pressure inside the container is not lower than the preset pressure, so as to ensure safety of the container body.
A method of controlling a cooling device for a reefer container according to the invention will be described below.
The controlling circuit of the cooling device comprises a compressor relay, a condenser fan relay and an evaporator fan relay connected in parallel as well as a controller for controlling operating states of the compressor relay, the condenser fan relay and the evaporator fan relay. The controlling circuit further comprises a pressure switch which is connected to the compressor relay in series and a pressure sensing and controlling device which can control the pressure switch to turn on or off. The controlling method comprises the following steps: measuring the air pressure inside the container by the pressure sensing and controlling device; when the air pressure inside the container drops to the preset pressure, controlling the pressure switch to turn off by the pressure sensing and controlling device, when the air pressure N MWeboume\Case\Patent\71000-71999\P7]996 ALASp is\P71996 AU Gi Spei as fileddoc 3/05/07 11 inside the container rises higher than the preset pressure, controlling the pressure switch to turn on by the pressure sensing and controlling device. By way of the above controlling method, the air pressure inside the container can be ensured to be not lower than the preset pressure value, and so to ensure safety of the container body.
00 The controlling circuit may be provided with the time delay relay 6 which is controlled by the pressure sensing and (Ni controlling device and can delay the pressure switch 7 to turn on. The time delay relay 6 is connected in parallel to the (1 pressure switch 7 and the compressor relay 1 connected in series.
In this case, when the air pressure inside the container drops to the preset pressure, the pressure sensing and controlling device controls a contact of the time delay relay to disconnect; and when the air pressure inside the container rises higher than the preset pressure, the pressure sensing and controlling device controls the contact of the time delay relay to connect, and the time delay relay 6 delays the pressure switch 7 to turn on. By way of the above controlling method, the cooling system will stop operating for a period of time after the air pressure inside the container drops to the preset pressure. Thereby such a risk is prevented that the container is damaged due to the temperature inside the container dropping and the air pressure rapidly dropping in the case that the cooling system continuously operates.
The pressure sensing and controlling device comprises a controlling device and a pressure sensor which is disposed inside the container. At this case, the air pressure inside the container is detected by the pressure sensor, and the controlling device acquires information of the air pressure inside the container from the pressure sensor and transmits control signals. Furthermore, the pressure sensing and controlling device can be a vacuum pressure switch.
