Problems solved by technology

[0011] However, in the existing cooler, the control unit uses the sensor to detect the result and adjusts the opening of the expansion valve through electronic control, so there will be stability problems caused by the control algorithm
In addition, a plurality of sensors and a control section for controlling the level of liquid refrigerant are separately required, resulting in a problem of increased manufacturing cost

Abstract

The present invention provides a cooling system. The cooling system includes: a compressor for compressing refrigerant; a condenser for exchanging heat between cooling water and refrigerant discharged from the compressor; and a flow regulating device provided at the condenser One side of the refrigerant outlet of the condenser is used to adjust the amount of refrigerant inside the condenser. The flow regulating device includes: a main body that communicates with the piping on the outlet side of the condenser; a supply pipe extending from the condenser to the main body for supplying the refrigerant inside the condenser to the inside of the main body; and a flow hole formed in the main body by The pressure of the refrigerant flowing in through the refrigerant supply pipe is selectively opened and closed.

Description

[0001] This application is based on the application number 10-2016-0014255, the application date is the Korean patent application filed on February 04, 2016, and claims the priority of the Korean patent application, and the entire content of the Korean patent application is hereby incorporated into this application as refer to. technical field [0002] The present invention relates to cooling systems. Background technique [0003] Generally, a chiller is used to supply cold water to a place where cold water is needed, and is characterized in that the cold water is cooled by exchanging heat between refrigerant circulating in a cooling system and cold water circulating between a place where cold water is needed and the cooling system. Chillers are large-capacity equipment and can be installed in large-scale buildings, etc. [0004] The cooler includes a compressor, an evaporator, a condenser and an expansion valve. The compressor may include an impeller (Impeller) that is ro...
