Thread Content
This post was last edited by YORK Industrial Refrigeration on 2017-12-4 at 09:22. Starting from now, in order to enhance communication among users, a 【Daily Question】 activity 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. Please explain the function of a high-pressure liquid receiver. Answer: 1. To ensure a steady supply and regulate the flow rate of the refrigerant liquid in the cooling system. 2. To store the liquid refrigerant that comes out of the condenser, thereby allowing the heat transfer surface area of the condenser to function effectively. 3. To maintain a certain liquid level in the receiver, creating a liquid seal that prevents the refrigerant gas in the high-pressure system, as well as non-condensable gases such as air mixed in with it, from entering the low-pressure system pipelines. https://attach01.hcbbs.com/forum/201712/01/094817hsdgrqsnnbnkhnv1.jpg Layer 1.jpg (28.41 KB, Downloads: 0) Download attachment; Save to album.

(1) Regulate the supply and demand of refrigerant liquid between the condenser and the evaporator. (2) Prevent excessive liquid refrigerant from accumulating in the condenser, as this will reduce the heat transfer area of the condenser and lead to an increase in the condensing pressure; therefore, the condensed liquid refrigerant must be removed promptly. (3) Maintain a certain liquid seal in the reservoir to prevent the refrigerant gas in the high-pressure system, along with non-condensable gases such as air mixed in it, from leaking into the pipelines of the low-pressure system.
(1) Store the condensate from the condenser to prevent excessive accumulation of condensate within it, which could reduce the heat transfer area and affect the condenser’s heat transfer efficiency. (2) Meeting the demand for supply volume in response to changes in the evaporator’s load: As the evaporation load increases, the supply volume also increases, with the liquid stored in the reservoir being used to supply it ； As the load decreases, the amount of liquid required also decreases, and the excess liquid is stored in a reservoir. (3) As a liquid seal between the high-pressure and low-pressure sides of the system, since the liquid outlet pipe is inserted below the liquid level, it prevents steam and non-condensable gases from the high-pressure side from entering the low-pressure side. At the same time, the reservoir also serves to filter and dampen noise.
In a refrigeration system, it is used to regulate and stabilize the flow rate of ammonia liquid, as well as to store ammonia liquid.
The high-pressure liquid receiver is used to store the refrigerant liquid that has condensed in the condenser. Its main functions are: (1) to regulate the supply and demand of refrigerant liquid between the condenser and the evaporator. (2) Prevent excessive liquid refrigerant from accumulating in the condenser, as this will reduce the heat transfer area of the condenser and lead to an increase in the condensing pressure; therefore, the condensed liquid refrigerant must be removed promptly. (3) Maintain a certain liquid seal in the reservoir to prevent the refrigerant gas in the high-pressure system, along with non-condensable gases such as air mixed in it, from leaking into the pipelines of the low-pressure system. For small-capacity refrigeration systems, as well as Freon refrigeration systems that use non-full-liquid evaporators, since the amount of refrigerant in such systems is small, the condenser and the receiver are combined, with the space below the condenser being used to store a certain amount of refrigerant; this configuration is referred to as a “condenser-receiver”.
Function of the high-pressure receiver: It stores the liquid refrigerant coming from the condenser, ensuring that the heat transfer area of the condenser can be utilized fully; it supplies and regulates the flow rate of liquid to various components within the refrigeration system, thereby adapting to changes in operating conditions; it also acts as a liquid seal to prevent gases from the high-pressure side from entering the low-pressure system and causing accidents.

The high-pressure liquid receiver is generally installed between the condenser and the throttling element, and it serves two purposes: (1) During operation of the refrigeration system, when there are changes in operating conditions or adjustments are made to the system, the refrigerant can be returned to the receiver, thereby stabilizing the amount of refrigerant circulating within the system and ensuring that the refrigeration unit operates properly. (2) When a fault occurs in a certain part of the refrigeration unit and repair is required, the refrigerant in the system can be collected in the liquid receiver through specific procedures, thereby preventing waste caused by large amounts of refrigerant leaking out.
The high-pressure liquid receiver is used to store the refrigerant liquid that has condensed in the condenser, thereby accommodating changes in the amount of refrigerant required by the cooling system as operating conditions change, and reducing the frequency of refrigerant refilling over time. Its main functions are: (1) regulating the supply and demand of refrigerant liquid between the condenser and the evaporator.

It is used to store the high-pressure liquid refrigerant from the condenser, in order to accommodate changes in the amount of refrigerant required by the cooling system as operating conditions change, and to reduce the frequency of refrigerant replenishment throughout the year.
