Fig. 1 is a partial structural diagram of a water chiller provided by an embodiment of the utility model. Please refer to Fig. 1, the water chiller is used to cool down the main equipment, the water chiller includes a main tank 11 for containing coolant 10, and an auxiliary tank 12 connected to the bottom of the main tank 11, the auxiliary tank 12 is provided with a detection device 13, the detection device 13 is used to detect the liquid level information of the coolant 10, when the coolant 10 reaches the set position, the detection device 13 transmits the abnormal liquid level signal to the main equipment.

The main equipment uses the ice machine to cool down. When the detection device 13 transmits the abnormal liquid level signal to the main equipment, the operator can obtain the need for liquid replenishment from the main equipment, thereby avoiding the operator's subjective judgment on whether liquid replenishment is needed and avoiding shutdown problems caused by lack of liquid.

It should be noted that FIG. 1 is only a simplified diagram of the water chiller. In fact, the water chiller may further include multiple components, such as a circulation loop, to circulate the coolant. The circulation loop may include an input pipeline and an output pipeline. The coolant 10 is input into the main tank 11 from the input pipeline, and the coolant 10 in the main tank 11 is output from the output pipeline, so that the coolant 10 completes the circulation. The water chiller may further include a circulation pump to complete the circulation of the coolant 10. A temperature sensor may further be provided on the input pipeline, and a temperature sensor, a pressure sensor, a flow sensor, etc. may further be provided on the output pipeline, but the utility model does not limit this.

As shown in FIG1 , the bottom of the auxiliary tank 12 is connected to the bottom of the main tank 11, thereby forming a U-shaped tube, so that the liquid level of the coolant 10 in the main tank 11 is the same as the liquid level of the coolant 10 in the auxiliary tank 12, so that the liquid level in the main tank 11 is obtained by detecting the liquid level of the auxiliary tank 12. In this embodiment, the top of the auxiliary tank 12 is also connected to the top of the main tank 11, but it is not limited thereto.

In this embodiment, the detection device includes a sensor. When the liquid level of the coolant 10 reaches a set position, the state signal of the sensor changes, and the main device receives the state change signal of the sensor, thereby issuing an alarm. The set position is the allowed capacity limit of the coolant 10 in the main tank 11, that is, the coolant 10 cannot be lower than or higher than the limit, and the limit of the coolant 10 can be determined according to actual conditions.

The sensor may be a capacitive sensor, a laser sensor, a microwave sensor or an electromagnetic sensor, etc. In this embodiment, the sensor is preferably a capacitive sensor. The capacitive sensor is disposed on the outer side wall of the auxiliary tank 12, that is, disposed on the outer side of the side wall of the auxiliary tank 12.

In one embodiment of the present application, the detection device 13 includes a capacitive sensor, which is arranged on the outer wall of the auxiliary tank 12 corresponding to the lower limit of the coolant 10, that is, the coolant 10 in the main tank 11 has the minimum allowed capacity, and the capacitive sensor is arranged on the outer wall of the auxiliary tank 12 where the liquid level of the coolant 10 is at the minimum capacity. When the coolant is lower than the lower limit, the state signal of the capacitive sensor changes, and the main device receives the state change signal of the capacitive sensor.

In another embodiment of the present application, the detection device 13 includes two capacitive sensors, the first capacitive sensor is arranged on the outer wall of the auxiliary tank 12 corresponding to the lower limit of the coolant, and the second capacitive sensor is arranged on the outer wall of the auxiliary tank 12 corresponding to the upper limit of the coolant. That is, the coolant 10 in the main tank 11 has the minimum and maximum allowed capacities, the first capacitive sensor is arranged on the outer wall of the auxiliary tank 12 where the liquid level of the coolant 10 is located when the capacity is minimum, and the second capacitive sensor is arranged on the outer wall of the auxiliary tank 12 where the liquid level of the coolant 10 is located when the capacity is maximum. When the coolant 10 is lower than the lower limit, the state signal of the first capacitive sensor changes, and when the coolant is higher than the upper limit, the state signal of the second capacitive sensor changes, and the main device receives the state change signal of the first capacitive sensor and/or the second capacitive sensor.

In this embodiment, when there is a lack of liquid, the main device receives a signal from the first capacitive sensor, and when there is too much coolant, the main device receives a signal from the second capacitive sensor, thereby ensuring that the liquid level range of the coolant 10 is under the monitoring of the main device.

FIG2 is a schematic diagram of the change in liquid level and the change in state of the capacitive sensor provided by an embodiment of the utility model. Please refer to FIG2. When the liquid level of the coolant 10 is between the first capacitive sensor 131 and the second capacitive sensor 132, the second capacitive sensor 132 is above the liquid level, that is, in one state, such as the first state, and the first capacitive sensor 131 is below the liquid level, that is, in another state, such as the second state. When the liquid level of the coolant 10 drops and is below the first capacitive sensor 131, the state of the first capacitive sensor 131 changes, for example, from the second state to the first state. The main device receives the state change signal of the first capacitive sensor 131, and can determine that the ice machine is in a state of lack of liquid.

It can be understood that when adding liquid, if the liquid level of the coolant 10 rises and the second capacitive sensor 132 is below the liquid level (not shown), the state of the second capacitive sensor 132 changes, for example, from the first state to the second state. Then, the main device receives the state change signal of the second capacitive sensor 132 and can determine that there is too much coolant 10 in the chiller.

In this embodiment, the ice machine may further include a relay (not shown). When the ice machine is too far from the main device, the relay is used to strengthen the abnormal liquid level signal of the detection device 13 and transmit it to the main device. FIG3 is a schematic diagram of the state of the relay provided in an embodiment of the utility model when no fluid replenishment is required and when fluid replenishment is required. Please refer to FIG3. For the relay, the first capacitive sensor 131 and the second capacitive sensor 132 are equivalent to two switches. When no fluid replenishment is required, the first capacitive sensor 131 is in the second state, and the second capacitive sensor 132 is in the first state, that is, the first capacitive sensor 131 is below the liquid surface, and the second capacitive sensor 132 is above the liquid surface. The first capacitive sensor 131 is in the disconnected state, and the second capacitive sensor 132 is in the on state. At this time, the relay is in the disconnected state and does not transmit the liquid level signal. When liquid replenishment is needed, the first capacitive sensor 131 and the second capacitive sensor 132 are both above the liquid level, and the first capacitive sensor 131 and the second capacitive sensor 132 are both in the first state, that is, the first capacitive sensor 131 changes from the second state to the first state. At this time, the first capacitive sensor 131 is in a conducting state, and the second capacitive sensor 132 is also in a conducting state. At this time, the relay is in a conducting state, and the liquid level signal is transmitted to the main device.

In the ice machine provided by the utility model, a detection device 13 is arranged on the auxiliary tank 12, and the detection device 13 is used to detect the liquid level information of the coolant 10. When the liquid level of the coolant 10 reaches the set position, the detection device 13 transmits the abnormal liquid level signal to the main device, and the operator can obtain the liquid replenishment demand from the main device, thereby avoiding the operator's subjective judgment on whether liquid replenishment is needed and avoiding the shutdown problem caused by lack of liquid.

Furthermore, two capacitive sensors are provided on the outer wall of the auxiliary tank 12. When the coolant 10 is lower than the lower limit, the state signal of the first capacitive sensor 131 changes, and when the coolant 10 is higher than the upper limit, the state signal of the second capacitive sensor 132 changes. That is, when there is a lack of liquid, the main device receives the signal sent by the first capacitive sensor 131, and when there is too much coolant, the main device receives the signal sent by the second capacitive sensor 132, thereby ensuring that the liquid level range of the coolant 10 is under the monitoring of the main device.

Correspondingly, the utility model also provides a cooling system, which includes the above-mentioned ice water machine and a main device for cooling using the ice water machine.

In this embodiment, the cooling system further includes an alarm monitoring system (AMS, Alarm Monitoring System), and the main device transmits the abnormal liquid level signal (i.e., the abnormal liquid level signal emitted by the detection device 13) to the alarm monitoring system, and the monitoring alarm system emits an alarm. The alarm monitoring system is a system that is matched with the main device, that is, when the main device itself is abnormal, it will transmit a signal to the alarm monitoring system. In this embodiment, the abnormal liquid level signal emitted by the detection device 13 is transmitted to the main device, and the main device transmits the abnormal liquid level signal to the alarm monitoring system.

FIG4 is a flow chart of the cooling system alarm provided by an embodiment of the utility model. Please refer to FIG1 and FIG4. When the liquid level of the coolant 10 reaches the set position, the detection device 13 sends a liquid level abnormality signal and transmits it to the main device. The main device receives the liquid level abnormality signal, and the main device interacts with the chiller signal for verification, and transmits the liquid level abnormality signal to the alarm monitoring system, and the alarm monitoring system sends an alarm. In this embodiment, the alarm monitoring system can also send the alarm information to the on-duty mobile phone, so as to remind the operator to add liquid to the chiller in time.

It should be noted that when the cooling system is established or debugged, it will be determined whether the signal of the detection device can be transmitted normally, whether the main device can receive the signal normally, and the signal representing the abnormal liquid level of the chiller is stored in the main device as the original signal. When the cooling system is operating normally, the main device receives the liquid level signal sent by the detection device, and compares the signal with the original signal to determine whether the liquid level of the chiller is abnormal, that is, the main device and the chiller signal are interactively verified.

In this embodiment, the operator can replenish the liquid to the chiller in time according to the prompt of the alarm monitoring system, thereby avoiding the operator's subjective judgment on whether liquid replenishment is needed and avoiding shutdown problems caused by lack of liquid.

In summary, in the ice machine and cooling system provided by the utility model, a detection device is arranged on the auxiliary tank, and the detection device is used to detect the liquid level information of the coolant. When the liquid level of the coolant reaches the set position, the detection device transmits the abnormal liquid level signal to the main equipment, and the operator can obtain the liquid replenishment demand from the main equipment, thereby avoiding the operator's subjective judgment on whether liquid replenishment is needed and avoiding shutdown problems caused by lack of liquid.

Furthermore, two capacitive sensors are provided on the outer wall of the auxiliary tank. When the coolant is lower than the lower limit, the state signal of the first capacitive sensor changes, and when the coolant is higher than the upper limit, the state signal of the second capacitive sensor changes. That is, when there is a lack of coolant, the main device receives the signal sent by the first capacitive sensor, and when there is too much coolant, the main device receives the signal sent by the second capacitive sensor, thereby ensuring that the liquid level range of the coolant is under the monitoring of the main device.

It should be noted that the embodiments in this specification are described in a progressive manner, and the structures described later focus on the differences from the methods described previously, and the similarities and similarities between the various parts can be referred to each other.
