Starting from now, in order to enhance communication among users, a \"Question of the Day\" campaign has been launched on the Mechanical Equipment Technology forum. We hope everyone will participate actively to progress and improve together! ! ! Rewards: 3 wealth points for active participation, 10-15 wealth points for correct answers. This question is valid for two days; no scoring will be given after that period. Last time we talked about the low-pressure circulation tank – please explain its function. Answer: The low-pressure circulation tank is one of the key components used in forced liquid supply refrigeration systems for cold storage. It is installed on the return pipe line from the evaporator to the compressor, and its main functions are: ① To separate the ammonia liquid contained in the return gas coming from the evaporator, thereby preventing liquid slugging in the compressor ； ②Separate the volatile gases generated by throttling of the ammonia liquid to prevent these gases from entering the evaporator ； ③Maintain the liquid level to ensure the ammonia pump supplies liquid to the evaporator. ④Separate the lubricating oil supplied into the refrigerant liquid inside it. ⑤It can also serve to remove frost and drain liquid from small cold storage units. timg.jpg (31.22 KB, downloads: 0) Download attachment; save to album.

The low-pressure circulation tank is a type of circulation tank used in ammonia pump-fed refrigeration systems. Its function is to ensure an adequate supply of low-pressure ammonia liquid to the ammonia pump; it also acts as an ammonia liquid separator, ensuring that only gaseous refrigerant flows into the compressor’s suction chamber.
As a buffer and storage for the circulating fluid

1. Separate the ammonia liquid contained in the return gas coming from the evaporator, in order to prevent liquid slugging in the compressor. 2. Separate the volatile gases generated by throttling of the ammonia liquid, so as to prevent these gases from entering the evaporator. 3. Maintain an appropriate liquid level to ensure that the ammonia pump can supply liquid to the evaporator. 4. Separate the lubricating oil present in the refrigerant liquid supplied to it. 5. In smaller systems, it can also serve to remove frost and drain excess liquid.

Its function is to maintain the highest water level while allowing air in the water to be expelled from here, thereby preventing it from entering the piping system and causing pressure losses due to air pockets. Cold water inlet baffles are installed at the bottom of the circulating water tank. In this way, when cold water enters the circulation tank, it is dispersed through the baffle so as to flow in without mixing the hot water at the upper part of the tank.
