The constant pressure water replenishment device is a commonly used constant pressure water replenishment equipment in air conditioning and heating systems. Water is widely used in many shopping malls, factories, and modern office buildings

Ethylene glycol, as a heat transfer medium, can automatically stabilize and replenish water in central air conditioning systems or other systems. Compared with traditional open expansion water tanks, it has the advantages of flexible installation position, no noise pollution, and no gas pollution. Therefore, it has been widely used in the HVAC constant pressure industry.

In a closed-loop system, expansion facilities need to be adjusted to ensure the stability of system pressure. When the system pressure decreases, the water chamber pressure of the pressure tank connected to it also decreases, the volume of the air chamber expands, and the pressure also decreases. When the control system is set to *, the water pump automatically turns on to replenish the system until the setting is reached. Set the upper pressure limit and stop the pump from running. When the water in the system is heated, the temperature rises, the volume expands, the air chamber is compressed, and the pressure of the pressure system increases. When the limit value is reached, the water in the system enters the expansion machine (or softened water tank) through the safety release device. The system pressure also drops to the set value and stops pressure release. Achieve the function of constant pressure water replenishment.
