きる。Conventionally, there has been a centralized load system in which a plurality of refrigerators each installed in a showcase or the like in a supermarket or the like is connected to a main operation panel through a signal line to centrally control the operation of these refrigerators. 1” control system is used. A temperature sensing element such as a thermostat is provided in each showcase corresponding to each refrigerator, and a signal corresponding to the operating state of each temperature sensing element is input to the main control panel. The main operation panel controls the operation of each refrigerator by inputting a predetermined duty cycle on/off signal, ie, a control signal, to the corresponding load device according to the operating state of each temperature sensing element. For example, a certain
If the temperature sensing element corresponding to one of the refrigerators is on, this indicates that the temperature inside the showcase where the temperature sensing element is installed is higher than the set temperature, so the main operation panel will turn on the showcase. A control signal with a large duty cycle, that is, a control signal with a long ON period, is input to the refrigerator that freezes, thereby increasing the operating time of the refrigerator within a predetermined time and controlling the temperature inside the refrigerator showcase to be lower. . On the other hand, if the temperature sensing element is off, it indicates that the temperature inside the showcase is lower than the set temperature.
The main control panel inputs a control signal with a smaller duty cycle to the corresponding refrigerator to shorten the operation time of the refrigerator within a predetermined period of time, thereby controlling the cooling operation in the showcase to be weak. For example, the main operation panel controls the operation of multiple refrigerators on/off based on signals from the corresponding temperature sensing elements through time-sharing operations by a microcomputer, thereby centrally controlling the operation of multiple refrigerators. can be done. Note that the temperature in each showcase can be individually adjusted by setting the temperature of a temperature sensing element provided for each showcase using a dial or the like.

If the room temperature is [1 or less, the on-time of the load device is controlled to a value below, for example, wi, and if the room temperature is higher than (1 (2 or less), the on-time of the load device is controlled from Wl to W2, and if the room temperature is higher than t2, the on time of the load device is controlled to be W2.
longer or turn on the load device continuously. By such fli control, the on-time of the load device is adjusted according to each temperature range, and, for example, the temperature of a refrigerator is controlled. For example, in the load device 2-1, a control signal is received from the control unit 4 via the signal line 8, and the electromagnetic relays 1i-i'i are turned on and off by this control signal.
Then, the power source V is turned on or cut off to the C load device 10-1. In this way, the control unit 4 controls each temperature sensing element 6-1.
and each load device 2 based on the temperature detection information from 6-2.

可能である。In this case, the period T in which the on/off operation of each load device is repeated is controlled to be a constant value of, for example, about 50 minutes. In this case, the period T of the on/off operation, the duty cycle, etc. are determined based on timing pulses generated by a clock 6 provided on the main operation panel 1. In addition, the user

する等のように決めることができる。By the way, in the system shown in FIG. 1, it is possible to individually adjust the duty cycle for each load device using the program key 7 provided on the operation section 5. For example, by inputting the number of a load device and the temperature setting number of the load device from the program key 7, the set temperature of the corresponding load device can be changed from the standard temperature setting. As the temperature setting number, for example, if you want to set the temperature lower than the standard setting temperature, you can key in 1', and if you want to set it higher than the standard setting temperature, you can key in R.

ユーティサイクルが決定される。For example, as shown in Figure 6, there are two load devices A and B. Load device A has no particular temperature setting number entered and therefore has a standard temperature setting, and load device B has a temperature setting of If setting number 1 is input, and therefore the temperature is set lower than the standard, the operation in each temperature range is performed as follows. That is, when the room temperature is below Ll, the duty cycle of the load A, that is, W/T, which is set at a standard temperature, becomes G by, for example, 50 degrees, as shown in FIG. 6, la. At this time, the duty cycle of load B, which is set at a temperature lower than the standard set temperature, becomes 50% or more, and the on time becomes longer. The room temperature is Ll 4) High and 1
2 or less, the duty cycle of load A becomes larger than, for example, 50 inches, as shown in FIG. 6, 1b+, and the on-time of the refrigerator, etc. increases and becomes longer. The duty cycle of load J3 is even greater than in the case of FIG. 5 la) and the on-time is even longer. And the room temperature is L
If it is higher than 2, as shown in FIG. 6, 1cl, for example, both loads A and B are operated continuously, and more powerful cooling is performed. Through such control, the temperature of load device B is controlled to be lower than that of load device A, but this depends on the type of products placed in the showcase, for example when the load device is a refrigerator in a showcase. This is useful when you want to set the temperature individually depending on the temperature. For example, vegetables, etc. can be kept at a relatively high temperature, so it is possible to have a long off time, whereas fish or frozen foods, etc. need to be kept at a lower temperature, so the off time can be shortened. It is necessary to extend the operating time of the refrigerator. Even in such a case, the system shown in FIG. 1 is advantageous because it is possible to set the temperature individually for each load device, so that it can be easily handled. Note that the load device number and set temperature number written above and inputted from the program key 7 are decoded in the control unit 4 and used together with the room temperature information from each temperature sensing element 6-1 and 6-2. The duty cycle of is determined.

Moreover, although the above description has been made regarding the case of salinity control, it is clear that the system of the present invention is not limited to the case of temperature control, but can also be applied to, for example, humidity control and other cases.

。As described above, according to the present invention, in a system in which a plurality of load devices are centrally controlled from a main operation panel, temperature detection is performed using a plurality of temperature sensing elements set at different operating temperatures. Since it is possible to perform detailed control and to adjust the temperature individually for each load, it is possible to fully respond to the diversification of usage conditions of each load device.
