Based on the same invention concept, the invention also provides a control method of the multifunctional fire water tank, which specifically comprises the following operation flow control processes:
for convenience of description, the water storage tank 3 closest to the refrigeration equipment 4 is set as a first water storage tank (namely, the water storage tank at the leftmost end in fig. 1), and the water storage tank 3 farthest from the refrigeration equipment 4 is set as a second water storage tank (namely, the water storage tank at the rightmost end in fig. 1);
the cold accumulation circulation loop operation flow control process:
when the controller 7 receives an operation signal of the refrigeration equipment 4, the controller 7 sends a control signal to open a first one-way electromagnetic valve connected with an upper circulation branch pipe of the first water storage tank and a second one-way electromagnetic valve connected with a lower circulation branch pipe of the first water storage tank, and cold water prepared by the refrigeration equipment 4 enters from the lower end of the first water storage tank and is stored in the first water storage tank;
when the first water storage tank is full of cold water, the controller 7 sends out a control signal to close a first one-way electromagnetic valve 32 connected with the upper circulation branch pipe 31 of the first water storage tank and a second one-way electromagnetic valve 34 connected with the lower circulation branch pipe 33, simultaneously open the first one-way electromagnetic valve 32 connected with the upper circulation branch pipe 31 of the water storage tank adjacent to the first water storage tank and the second one-way electromagnetic valve 34 connected with the lower circulation branch pipe 33, store cold water into the adjacent water storage tanks, and then store cold water into the water storage tanks sequentially according to the sequence from the first water storage tank to the second water storage tank until the second water storage tank is full of cold water;
specifically, in the cold storage circulation loop operation flow control process, referring to fig. 3, in order to accelerate the cold storage process, the refrigeration device 4 may be connected in parallel to the cold storage circulation loop, in an initial state of the cold storage circulation loop operation flow control process, the first one-way solenoid valve 32 and the second one-way solenoid valve 34 connected to each water storage tank 3 are both in a closed state, and the first three-way solenoid valve 13 and the second three-way solenoid valve 14 are in conduction in the 1 and 2 directions (as shown in fig. 3). When the controller 7 receives an operation signal of the refrigeration equipment 4, the controller 7 sends a control signal, the first one-way solenoid valve 32 connected with the upper circulation branch pipe 31 of the first water storage tank 3 and the second one-way solenoid valve 34 connected with the lower circulation branch pipe 33 are opened, cold water prepared by the refrigeration equipment 4 enters from the lower end of the first water storage tank 3, and hot water flows out from the upper end of the first water storage tank 3 (it can be understood that when the refrigeration equipment 4 drives the cold water to have insufficient circulation power, a circulation water pump can be additionally arranged on the circulation main pipe 11). When the first water storage tank 3 is full of cold water, the controller 7 sends out a control signal to close the first one-way solenoid valve 32 connected with the upper circulation branch pipe and the second one-way solenoid valve 34 connected with the lower circulation branch pipe of the first water storage tank 3, and open the first one-way solenoid valve 32 connected with the upper circulation branch pipe 31 of the water storage tank 3 adjacent to the first water storage tank and the second one-way solenoid valve 34 connected with the lower circulation branch pipe 33 to store cold water for the water storage tank 3. And analogizing in turn until the last water storage tank 3 on the left side is full of cold water as shown in fig. 3, all the first one-way electromagnetic valves 32 and the second one-way electromagnetic valves 34 are closed, the refrigeration equipment 4 stops running, and the running flow control process of the cold accumulation circulation loop is completed.
The control process of the operation flow of the cooling circulation loop comprises the following steps:
when the controller 7 receives an operation signal of the cooling equipment 5, the controller 7 sends a control signal to drive the first three-way electromagnetic valve 13 and the second three-way electromagnetic valve 14 to act so as to connect the cooling equipment 5 into the main circulation pipe 11, and simultaneously opens the first one-way electromagnetic valve 32 connected with the upper circulation branch pipe 31 of the second water storage tank and the second one-way electromagnetic valve 34 connected with the lower circulation branch pipe 33, so that cold water required by the cooling equipment 5 flows out from the lower end of the second water storage tank, and cold water is provided for the cooling equipment 5;
when the cold water in the second water storage tank is used up, the controller 7 sends out a control signal to close a first one-way electromagnetic valve 32 connected with the upper circulation branch pipe 31 of the second water storage tank and a second one-way electromagnetic valve 34 connected with the lower circulation branch pipe 33, simultaneously open the first one-way electromagnetic valve 32 connected with the upper circulation branch pipe 31 of the water storage tank adjacent to the second water storage tank and the second one-way electromagnetic valve 34 connected with the lower circulation branch pipe 33, call the cold water in the adjacent water storage tank, and then call the cold water in the water storage tank in sequence from the second water storage tank to the first water storage tank until the cold water in the first water storage tank is used up;
specifically, in the cooling circulation circuit operation flow control process, referring to fig. 4, in the initial state of the cooling circulation circuit operation flow control process, in which the cold accumulation circulation process has been completed, the first one-way solenoid valve 32 and the second one-way solenoid valve 34 to which each of the water storage tanks 3 is connected are both in the closed state. When the controller 7 receives an operation signal of the refrigeration equipment 4, the controller 7 sends a control signal to conduct the directions 2 and 3 of the first three-way electromagnetic valve 13 and the second three-way electromagnetic valve 14 (as shown in fig. 4), and opens the first one-way electromagnetic valve 32 connected with the upper circulation branch pipe of the second water storage tank 3 and the second one-way electromagnetic valve 34 connected with the lower circulation branch pipe, so that the cold water required by the refrigeration equipment 4 flows out from the lower end of the second water storage tank 3, and the hot water enters from the upper end of the second water storage tank 3 (it can be understood that when the cold equipment 5 is used for driving the cold water circulation main pipe 12 to be additionally provided with a circulation water pump). When the cold energy of the cold water in the second water storage tank 3 is used up, the controller 7 sends out a control signal to close the first one-way solenoid valve 32 connected with the upper circulation branch pipe 31 of the second water storage tank 3 and the second one-way solenoid valve 34 connected with the lower circulation branch pipe 32, and simultaneously opens the first one-way solenoid valve 32 connected with the upper circulation branch pipe 31 of the water storage tank 3 adjacent to the first water tank and the second one-way solenoid valve 34 connected with the lower circulation branch pipe 33, so as to call the cold water in the water storage tank 3. And so on, then the cold water in the water storage tanks 3 is called in turn according to the sequence from left to right as shown in fig. 4, because the cold water is taken from the second water storage tank 3 at first, the pipeline is longer at the moment, the second water storage tank 3 is filled with the cold water in the process of cold releasing in the pipeline, and in addition, the closing and the opening of the water storage tanks 3 in the switching process can not influence the temperature of the water used by the cold equipment 5, thereby ensuring the stable operation of the cold equipment 5.
The fire-fighting water passage operation flow control process comprises the following steps:
when the fire-fighting water equipment 6 starts to operate, the controller 7 sends out control signals to close the first electromagnetic valves 32 above all the water storage tanks 3, open the second electromagnetic valves 34 below all the water storage tanks 3 and the third one-way electromagnetic valve 62 on the fire-fighting water pipe 61, and completely collect the water in the water storage tanks 3 into the fire-fighting water pipe 61 to supply water for the fire-fighting water equipment 6.
Specifically, in the firewater passage operation flow control process, referring to fig. 5, when the controller 7 receives an operation signal of the firewater equipment 6, the controller 7 sends a control signal to close the refrigerating equipment 4 or the cooling equipment 5 which is in operation, close the first three-way solenoid valve 13 and the second three-way solenoid valve 14, and close the first one-way solenoid valves 32 on the circulation branch pipes 31 on all the water tanks 3 and open the second electrically-operated solenoid valves on the circulation branch pipes 33 on all the water tanks 3. The water in all the water storage tanks 3 is gathered into the main circulation pipe 11 through the lower circulation branch pipes 33 (it can be understood that the fire-fighting water tank itself has a fire-fighting function, and when the water pressure of the fire-fighting water equipment 6 is insufficient, a circulation water pump can be additionally arranged on the fire-fighting water pipe 61), so that a water source is provided for the fire-fighting equipment.
In the embodiment, through reasonable valve control logic, automatic control of all working conditions of the water storage tank is realized. The cold water produced by the refrigerating unit can be more efficiently utilized when the cold water is used as a water storage tank in daily life, the economy of the cold equipment 5 is improved, and the waste of energy is reduced. When the water for fire control is provided, the water supply amount during fire control can be ensured, and the original effect of the fire water tank is ensured.
As an optimization scheme, the present embodiment further sets the following monitoring process:
in the control process of the operation flow of the cold accumulation circulation loop, when the temperature monitored by the first temperature sensor 37 in a certain water storage tank 3 reaches a preset temperature (the cold accumulation temperature is 4 ℃), which indicates that the water storage tank 3 is full of cold water, the controller 7 sends out a control signal to close the first one-way solenoid valve 32 and the second one-way solenoid valve 34 connected with the water storage tank 3, and simultaneously opens the first one-way solenoid valve 32 and the second one-way solenoid valve 34 connected with the adjacent water storage tank 3 on the right side of the water storage tank 3 to accumulate cold water for other water storage tanks 3. When the temperature monitored by the first temperature sensor 37 in the water storage tank 3 at the rightmost end reaches a preset value, the last water storage tank 3 is full of cold water, and the controller 7 sends a control signal to control the cold equipment 4 to stop running, so that the loss of electric energy is avoided.
