However, due to the limited capacity of the water tank, after the user connects the external pipe of the equipment to the target device, the external pipe and the target device will contain some liquid, which will cause the liquid level in the water tank to drop after the chiller is turned on. At this time, the user needs to add water to the water tank again. If the client uses multiple chiller equipment, this step will be repeated, resulting in a waste of manpower and reducing the operating efficiency of the equipment. The present application can realize automatic refilling of single / multiple chillers when in use, so as to achieve unified refilling of multiple chillers, which is particularly important. Through this integrated chiller automatic refilling system, the operating efficiency of the equipment can be improved and the maintenance cost can be reduced.

Therefore, the liquid level will be level).

[0062] refer to Figure 1 and Figure 2 When the machine is turned on for the first time, the water tanks 4-1 of each chiller and the replenishment water tank 3-2 are empty. At this time, the liquid level display tube 3-5 of the replenishment water tank will prompt a water shortage alarm message. If the user turns on the automatic replenishment function, the replenishment system will judge according to the signal of the liquid level sensor 3-7 in the replenishment water tank 3-2. If the liquid level sensor 3-7 is in a low liquid level state, the replenishment solenoid valve 2 of the replenishment level where the sensor is located will open, and pure water will flow into the replenishment water tank 3-2 through the pipeline until the liquid level sensor 3-7 reaches the high liquid level (liquid level sensor 3-7 When the high liquid level is equal to the liquid level at the maximum safe capacity of the chiller water tank 4-1), stop replenishing, and the liquid in the replenishing water tank 3-7 will naturally flow to the chiller water tanks 4-1 due to the atmospheric pressure (replenishment is carried out from the drain outlet of each chiller water tank 4-1, and each chiller 4 performs air pressure balance through the exhaust pipe). After the liquid level in the replenishing water tank 3-7 flows to the chiller water tank 4-1, the liquid level in the replenishing water tank drops, and the automatic replenishment conditions are triggered again. Repeat the above actions until the liquid level of each chiller 4 is replenished to a safe position.
