Description

Technical Field

[0001] The utility model relates to the technical field of water replenishment devices, in particular to a water replenishment device for a marine chiller. Background Art

[0002] The circulating water system of the marine chiller is a closed circulation system. When the refrigeration is running, it plays the role of transporting the refrigerant to the end of the air conditioner to cool the space. The amount of refrigerant in the circulating water system directly affects the efficiency of the air conditioner. If the amount of refrigerant is reduced and the pressure of the circulating water system is lower than the atmospheric pressure, air will enter the system. This air will accelerate the cavitation of the circulating water pump and occupy the heat exchange area of ​​the heat exchanger, affecting the heat exchange. With the increasing use of marine chillers on ships, the distribution areas are also becoming more and more extensive. In some cold areas, antifreeze is usually added to the circulating water system as a refrigerant, but there is rarely a set pressure water replenishment device to replenish the refrigerant in time. It is always until the unit is found to be faulty or the effect is not good that the lack of refrigerant is found and then added. The constant pressure water replenishment device can ensure that the circulating water system of the marine chiller has a constant pressure and effectively avoids various failures caused by the lack of refrigerant.

[0003] A constant pressure water replenishment device for a marine chiller is disclosed in the specification of the Chinese utility model patent application CN206399055U, which aims to ensure that the circulating water system of the marine chiller has a constant pressure to avoid various faults of the marine chiller caused by the lack of coolant. A constant-pressure water replenishment device for a marine chiller comprises a shell, a water pump, and a water pump base, wherein the water pump base is arranged on the top of the shell, the water pump and an electrical box are installed on the water pump base, and a liquid level switch is arranged at a preset low liquid level line at the internal height of the shell, the liquid level switch is electrically connected to a low liquid level alarm indicator light, and when the liquid level in the shell drops to the preset low liquid level line, the low liquid level alarm indicator light comes on, a liquid filling port cover is arranged on the top of the shell, the water outlet of the water pump is connected to the water replenishment port of a circulating water system, and the water inlet of the water pump is connected to a water inlet pipe, and the water inlet pipe passes through the water pump base and extends to the bottom of the shell, but the device does not solve the problem of easy movement and autonomous water replenishment. For this reason, we propose a water replenishment device for a marine chiller. Utility Model Content
