Description

Technical Field

[0001] The utility model relates to the technical field of energy storage chiller debugging, and more specifically, to a closed device for debugging an energy storage chiller. Background Art

[0002] The closed device for debugging energy storage chillers is a device used to debug energy storage chillers. Energy storage chillers are devices that use electricity during off-peak hours to cool water to low temperatures and store it, and then release the cooling capacity during peak hours. Debugging energy storage chillers requires simulating the real working environment and testing and adjusting their working performance.

[0003] A closed device is a closed environment that can control parameters such as temperature, humidity and air pressure to simulate a real working environment. When commissioning an energy storage chiller, using a closed device can provide stable working conditions and reduce the impact of external factors on test results.

[0004] Among them, it was found through search that the utility model patent with patent application number CN202120388820.8 discloses a device for automatically releasing the accumulated gas of closed circulating cooling water, which belongs to the technical field of circulating cooling water equipment and is used to automatically release the accumulated gas of closed circulating cooling water. Its technical scheme is: the cylinder is a steel cylinder with closed ends, an exhaust pipe is installed on the upper end of the cylinder, an automatic exhaust valve is installed on the upper end of the exhaust pipe, an inlet pipe and an outlet pipe are installed on both sides of the cylinder respectively, the diameters of the inlet pipe and the outlet pipe match the diameter of the main return pipe, the lower ends of the inlet pipe and the outlet pipe are respectively connected to the main return pipe, the inlet pipe is located upstream of the main return pipe, the connection port of the inlet pipe and the cylinder is lower than the connection port of the outlet pipe and the cylinder, and a main return pipe cut-off valve is installed on the main return pipe between the inlet pipe and the outlet pipe;

[0005] When this structure is in use, the two sides of the cylinder are connected in parallel above the main return pipe through the water inlet pipe and the water outlet pipe respectively. The main return pipe cut-off valve cuts off the main return pipe. The return water enters the cylinder through the water inlet pipe and flows back to the main return pipe from the water outlet pipe. The gas in the circulating water is discharged from the automatic exhaust valve on the top surface of the cylinder. The automatic exhaust inspection valve, manual exhaust inspection valve and manual exhaust valve can inspect and replace the automatic exhaust valve. However, this structure is not easy to quickly exchange the cold and heat sources to achieve the function of lowering the circulating water temperature when in use, and is not convenient enough when in use.
