(1) CO ≤ 0.0003

(2) A > 1.2

(3) Eff ≤ 95

Here, CO is the carbon monoxide concentration (%), A is the air ratio, and Eff is the operating efficiency (%) of the absorption type cold/hot water heater, respectively.

That is, the heating operation control step (S40) ends the processing when any one of the conditions (1) to (3) is not satisfied, and when all of the conditions are satisfied, the operation control step (S43) proceeds to the air ratio processing to control is performed.

In addition, in the heating operation control step (S40), the monitoring function may be provided in the same manner as shown in FIGS. Since it is the same as the cooling operation control step (S30), a description of the overlapping contents is omitted here.

Next, the specific contents of the pump operation control step (S20) of the operation control method for energy saving of the air conditioning system according to the embodiment of the present invention will be described.

First, referring to FIG. 15 , FIG. 15 shows the cooling water pump operation control step S50 in the pump operation control step S20 of the operation control method for energy saving of the air conditioning system according to the embodiment of the present invention shown in FIG. 3 . It is a flowchart schematically showing a specific configuration.

As shown in FIG. 15 , the cooling water pump operation control step S50 is roughly divided, similarly to the cooling operation control step S30 and the heating operation control step S40, various information and A data collection step (S51) in which a process for collecting data including a measurement value is performed, and a parameter related to operation and a current state are calculated based on the collected data, respectively, and whether operation control is executed according to a predetermined control condition The data analysis step (S52) in which the processing to determine It may be configured to include an operation control step (S53) in which a process of sending a notification requesting confirmation and adjustment to the user according to preset contents and performing operation control by adjusting each parameter until an appropriate level is achieved.

In other words, in general, when the operating flow rate of the cooling water pump is higher than the rated value, the temperature difference between the inlet and outlet temperature of the cooling water occurs below 5℃. The flow rate of the circulating coolant is increased, and the increase in the flow rate depends on the performance of the pump.

It can be configured to reduce the power consumption of.

Here, the control condition shown in FIG. 15 is only an embodiment of the present invention, and this determination criterion may be determined by applying an appropriate value based on the experience of those skilled in the art, or based on measured values such as temperature and flow rate previously measured for the system. Alternatively, it should be noted that, for example, it may be determined as an initial value reflecting a certain level of margin, such as 5% of the rated flow rate, etc., and may be configured in various ways according to need.

More specifically, when the coolant flow rate is higher than the rated flow rate and the pump operation efficiency is lower than the rated flow rate, an alarm is sent to inform that operation control is required (Example: Alarm name: Cooling water pump operation efficiency decrease, Action: Flow rate adjustment required (Rate flow <calculated value>)), at this time, the alarm is displayed in a list type in the table of the alarm page at the time and number of times (for example, within 3 times) preset by the user, and a pop-up window or text It may be configured to display or deliver the corresponding information in a message or e-mail, etc., so that processing is performed.

In addition, in the operation control step (S53), preferably, when it is determined that operation control is necessary, a notification is delivered as described above, and at the same time, the data is collected while changing each condition according to predetermined settings. By repeatedly performing the processing of step S51, data analysis step S52, and operation control step S53, the operation control process for optimizing the operation of the pump may be configured to be automatically performed.

In addition, in the cooling water pump operation control step (S50), the data collection step (S51), the data analysis step (S52) and the operation control step (S53) as shown in FIG. 15 are predetermined even after the processing is finished. By being configured to be automatically repeated at a certain period or interval according to the setting, for example, every 15 minutes, the cooling water pump can be configured to always operate in an optimal state, thereby improving the efficiency and performance of the overall air conditioning system improve and reduce energy consumption.

Moreover, although not shown, the cooling water pump operation control step (S50) is performed as described above, such as cooling water inlet and outlet temperature, cooling water temperature difference, COP, load factor, cooling water flow rate, lift, power consumption, pump discharge pressure, inverter frequency, etc. Further comprising an information providing step in which a process of periodically monitoring the operation and status of the same cooling water pump and outputting the result of comparing the power consumption of the cooling water pump before and after operation control as the status and operation information of the cooling water pump to the user is performed. can be configured.

More specifically, FIG. 16 shows items that the user can monitor for the heat dissipation operation state during the operation of the refrigerator, that is, the cooling water inlet and outlet temperatures are radiated from the cooling tower to lower the cooling water temperature and heat from the air conditioning system in the refrigerator. After absorption, the cooling water temperature rises, and the cooling water temperature difference causes the cooling tower to radiate the heat obtained from the refrigerator to the atmosphere, resulting in a temperature difference.

In addition, in the COP and the load factor shown in FIG. 16, the operating COP is the heat input (power consumption) versus the heat output (evaporation heat), and the chiller is generally 3.0 to 6.0, and the load factor is the amount of heat produced compared to the rated capacity of the chiller.
