Abstract

The invention discloses a refrigerator body foaming constant temperature unit power consumption scheduling method. The method comprises the following steps: preheating a constant-temperature unit; after preheating is completed, the central processing unit controls the electric power of the dispatching system to be (N/2 + 1) * single power, calculates the temperature difference absolute value Z DEG C of the constant-temperature units after receiving the temperature data of the constant-temperature units, and ranks the constant-temperature units according to the temperature difference absolute value Z DEG C; the molds are heated for the first N/2 + 1 constant-temperature units; and when the temperature difference sensor detects that the actual temperature Y DEG C of the mold reaches the set temperature X DEG C, the constant-temperature unit stops heating. According to the method, the heating sequence is determined through sorting according to the difference values, so that the maximum value of rated power can be effectively reduced, waste of power matching is avoided, and the power utilization safety is also improved; and the constant-temperature unit is preheated in advance, so that the time period when all constant-temperature machines work at full amount at the same time is avoided, and normal production and use are not affected.

Example Embodiment

[0024] Example 1:
[0025] see figure 1 As shown, the present invention is a method for dispatching electricity for a refrigerator box foaming thermostatic unit, including a dispatching system; the dispatching system includes a central processing unit and a thermostatic unit; the central processing unit and the thermostatic unit are electrically connected;
[0026] The central processing unit is also electrically connected with a control panel and a display module, and the control panel transmits control instructions to the central processing unit; the display module adopts an LED display screen, and the display module displays the temperature data of the thermostatic unit received by the central processing unit;
[0027] The thermostatic unit includes a controller, a temperature sensor, a heating module and a communication module. The controller is electrically connected to the temperature sensor, the heating module and the communication module respectively; the controller exchanges information with the central processing unit through the communication module; The instruction controls the heating module to heat the mold; the heating module is a heating wire, and the communication module adopts a WIFI communication module or a GPRS communication module or a 433 communication module.

Example Embodiment

[0028] Embodiment 2: Based on Embodiment 1
[0029] This embodiment is a method for dispatching electricity for a refrigerator box foaming and constant temperature unit, and the dispatching system operates according to the following steps:
[0030] Stp1. Number the thermostatic unit; the central processor controls the thermostatic unit to preheat; the preheating time is 30-60min; after the preheating is completed, the power consumption of the central processor control scheduling system is (N/2+1)*single unit Power, N is the number of constant temperature units, when N is an odd number, N/2 is rounded up to 1;
[0031] Stp2. The user inputs the set temperature X°C through the control panel, and the range of the set temperature X°C is 30-60°C; the controller in the constant temperature unit detects the actual temperature Y°C of the mold through the temperature sensor, and uploads it to the center through the communication module processor;
[0032] Stp3. After receiving the temperature data of the constant temperature unit, the central processor calculates the absolute value of the temperature difference of the constant temperature unit Z°C=X°C-Y°C, and sorts each constant temperature unit according to the size of the absolute value of the temperature difference Z°C;
[0033] Stp4, the central processing unit sorts Z1°C to Zn°C from large to small, and the central processing unit controls the absolute value of the temperature difference Z°C to sort the top N/2+1 constant temperature units to heat the mold;
[0034] Stp5. When the order of Z1°C to Zn°C changes from large to small, the central processing unit turns on or off the heating module of the corresponding constant temperature unit, and keeps the heated constant temperature unit from Z1°C to Zn°C from large to small. N/2+1; when there is a consistent temperature between Z1°C and Zn°C, the heating is performed in the order from large to small. When the temperature is consistent, the central processor controls the thermostatic unit with a smaller number to give priority to heating;
[0035] Stp6. When the temperature difference sensor detects that the actual temperature Y°C of the mold reaches the set temperature X°C, the controller transmits the signal to the central processing unit, and the central processing unit controls the constant temperature unit to stop heating.
