Embodiment 1

[0047] Such as figure 1As shown, this embodiment provides a vertical liquid reservoir that can overflow smoothly, including a cavity composed of a cylinder body 1, an upper seal body 2 and a lower seal body 3, and a partition device is provided in the cavity to separate the cavity It is divided into a buffer chamber 4 at the upper part and a liquid storage chamber 7 at the lower part, wherein a downcomer 5 and a gas flow channel 6 are arranged between the buffer chamber 4 and the liquid storage chamber 7, and the lower end of the downcomer 5 extends into the liquid storage chamber Below the minimum working liquid level of 7, prevent gas from entering from downcomer 5 lower ends.

[0048] The specific structure of the partition device is as follows, which includes a horizontal partition 41 and a vertical partition 42, wherein the horizontal partition 41 is located at the bottom of the buffer chamber 4 and part of the sides are fixed on the cylinder 1. The simpler way is to plac...

Embodiment 2

[0061] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that this solution adds a heat exchange tube 74 and an oil separator 8 under the liquid surface of the liquid storage chamber 7 .

[0062] When the heat exchange tube 74 is installed separately, it can transfer the cold energy to the refrigerant liquid in the liquid storage chamber 7 by passing the low-temperature and low-pressure refrigerant gas into the heat exchange tube 74, and the refrigerant gas in the heat exchange tube 74 It can be saturated or overheated after heating up, and it can avoid liquid shock when it is sucked by the compressor.

[0063] In order to realize the separation of oil and gas in the liquid receiver, in this embodiment, the oil separator 8 is placed in the refrigerant liquid (below the lowest working liquid level), so that the heat exchange tube 74 can also transfer the cooling capacity to the oil separator 8, At the same time, the oil separator 8 is conne...

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...
