Embodiment 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 w...

Embodiment 2

[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 te...

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.

Description

technical field [0001] The invention belongs to the technical field of refrigerator production control, in particular to a method for dispatching electricity for a refrigerator box foaming constant temperature unit. Background technique [0002] When the refrigerator box is foamed, it is necessary to use a constant temperature unit to heat the foaming mold. Generally speaking, 8 box foaming molds form a group, usually there are 2 groups in one production line, and each group of box hair molds has a total of 3 constant temperature units. The temperature of the bottom plate, the front and rear baffles, the left and right side plates, and the mold core are respectively controlled, so a production line is 6 constant temperature machines. These 6 thermostats are collectively referred to as thermostat units. The rated power of each thermostat is 50kw, and the rated power of the thermostat unit is 300kw. Therefore, when matching the power for the thermostat unit, it is necessary to...
