The present invention relates to an ice heat storage cooling apparatus including an ice making means, and more particularly, to an ice heat storage cooling apparatus including an ice making means using an ice making means (icemaker) rather than an external heat storage type heat storage method.

Generally, the ice storage cooling device refers to a device that freezes ice at midnight and melts it in the middle of the day without cooling the air conditioner during the day when electricity consumption is high.

Commonly known ice heat storage cooling apparatuses are divided into large ice heat storage cooling apparatuses which perform central cooling or small ice heat storage cooling apparatuses used for home use. The present invention is an improvement of a small ice heat storage cooling apparatus.

That is, Figure 6 is an overall configuration diagram showing a conventional ice heat storage cooling device.

In describing the operation of the cooling means according to the present invention, a cooling operation process by a normal cooling operation process and a bypass of cooling water and It will be described by dividing the operation process of the device due to the quenching of the cooling water.

First, FIG. 3 is an operation diagram showing a process in which the cooling means according to the present invention is normally operated. First, the first pipe 35 of the first pipe 35 is input to the memory unit 41 constituting the control means 4. Save the set temperature.

Next, the second pipe 36 is opened by driving the valve driving part 43 constituting the control means 4 to open the switching valve 361 of the second pipe 36, and the pump driving part of the control means 4. (44) is driven to allow the coolant to move to the heat exchange means (31) and the second tube (36) including a heat exchanger (313) provided in the first tube (35) and at least one room. That is, the cooling water is moved to the first tube 35, the heat exchanger 313, and the second tube 36 at a constant pressure through the operation of the pump 351.

Then, the cooling water moved to the second pipe 36 is introduced into the heat storage tank 1 through the cooling water supply pipe 33 to be in contact with the ice filled in the lower portion, thereby causing heat exchange, and thus the coolant causing the heat exchange is the first pipe. Each room is cooled by being moved through 35 to the above-described movement path.

In operation as described above, temperature data input from the first temperature sensor 352 and each room temperature sensor 32 and temperature data preset in the memory unit 41 are compared with each other. If the result does not deviate from the preset temperature range, the normal operation proceeds as described above through the control of the controller 42.

That is, the control part 42 which comprises the control means 4 outputs the opening control signal of the 1st pipe | tube 35 to the valve drive part 43, and outputs the drive control signal to the pump drive part 44, as mentioned above. The operation is in progress.

Thus, as described above, the process of cooling water is moved through the heat storage tank 1 through the control of the control means 4 to move the first pipe 35, the heat exchange means 31 and the second pipe 36. The process of cooling each room is performed.

When the cooling operation is performed as described above, the temperature data and the room temperature data input from the first temperature sensor 352 are compared with the corresponding temperature data preset in the memory unit 41, and the result is preliminary. When the temperature is lower than the set temperature range, the opening and closing degree of the switching valve 361 is adjusted through the control of the controller 42 to directly bypass the cooling water passing through the second pipe 36 to the first pipe 35. The temperature of the cooling water passing through the first pipe 35 is increased.

As it rises, it is possible to prevent the freezing phenomenon in the freezing wave of the tube or the heat exchanger 313 in advance.

In addition, as shown in FIG. 4B, when the temperature of the coolant passing through the second pipe 36 is lower than the set range, the controller 42 controls the valve pipe 43 and the second pipe 36 and the third pipe. By outputting a control signal in which all of the pipes 37 are opened, the coolant that moves the second pipe 36 and the coolant of the heat storage tank 1 flow into the first pipe 35 to pass through the first pipe 35. Increasing the temperature of the cooling water to prevent the freezing phenomenon in the freeze or heat exchanger 313 of the tube may be prevented in advance.

That is, by opening the switching valve 361 so that the second and third pipes 36 and 37 are partially opened, the temperature of the cooling water flowing into the first pipe 35 can be easily adjusted. Therefore, it is possible to improve the performance of the device by adjusting the temperature of the cooling water passing through the first tube 35 to the most ideal temperature.

5 is an operation diagram showing an operation process in which the cooling means according to the present invention is stopped due to rapid cooling.

Thus, as described above, the process of cooling water is moved through the heat storage tank 1 through the control of the control means 4 to move the first pipe 35, the heat exchange means 31 and the second pipe 36. The process of cooling each room is performed.

And the memory unit 41 constituting the control means 4 of the present invention further stores the allowable falling temperature data of the cooling water passing through the first pipe 35 through the input unit, the control unit is the first temperature sensor 352 It is characterized in that it further comprises outputting a control signal for stopping the operation of the pump drive unit 44 when the coolant temperature data input from the lower than the allowable falling temperature.

In addition, the controller 42 may further include outputting a warning means driving signal when the coolant temperature data input from the first temperature sensor 352 is lower than the allowable falling temperature, and the control means 4 is controlled by the controller. It further comprises a warning means 47 for outputting a warning sound in accordance with the warning means drive signal output.

Therefore, in the cooling operation as described above, the temperature data input from the first temperature sensor 352 and the allowable falling temperature data preset in the memory unit 41 are compared with each other, and the result is the allowable falling temperature data. If it is lower, the cooling water pipe and the second pipe constituting the first pipe 35 and the heat exchanger 313 by outputting a control signal for stopping the operation of the pump drive unit 44 through the control of the control unit 42. It is possible to prevent the breakdown of the device by preventing the freeze of (36) in advance.
