Vertical liquid reservoir and refrigerating system with liquid reservoir

Abstract

The invention discloses a vertical liquid reservoir. The vertical liquid reservoir comprises a cavity formed by a barrel, an upper sealing body and a lower sealing body, a separation device for separating the cavity into a buffer chamber and a liquid storage chamber, a downcomer, a gas flow channel and a liquid level control device; the downcomer and the gas flow channel are used for communicating the buffer chamber with the liquid storage chamber; the lower end of the downcomer stretches into the position below the lowest working liquid level of the liquid storage chamber; the upper sealing body is provided with a liquid inlet pipe entering the buffer chamber and a first gas outlet pipe keeping a proper distance from the liquid inlet pipe; a first liquid outlet pipe is arranged at the bottom of the buffer chamber; the lower sealing body is provided with a discharge port and a second liquid outlet pipe stretching into the liquid storage chamber; the liquid storage chamber is provided with a first gas inlet pipe located above the highest working liquid level; and the liquid level control device is used for controlling the liquid level height of the liquid storage chamber. According to the vertical liquid reservoir, the downcomer and the gas flow channel are arranged between the buffer chamber and the liquid storage chamber which are divided up and down, so that even if the pressure of the liquid storage chamber is high, the pressure in the liquid reservoir can be balanced, and it is ensured that liquid in the buffer chamber can smoothly flow into the liquid storage chamber through the downcomer.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a vertical liquid reservoir and a refrigeration system with the liquid reservoir. Background technique [0002] In a refrigeration system, a liquid receiver is usually provided. The function of the liquid receiver is to store the liquid refrigerant in the refrigeration system and continuously supply the liquid refrigerant to the low-pressure system. Part of the liquid reservoir also serves as a priority to supply liquid to the oil cooler. According to the principle of refrigeration, lowering the temperature of liquid refrigerant is beneficial to increase its unit cooling capacity. As for the liquid receiver that also gives priority to supplying liquid to the oil cooler, it also undertakes the function of separating the liquid droplets entrained in the return air of the oil cooler. [0003] The vertical liquid receiver is widely used because it can maintain the...
