The similarities and differences between open and water-cooled box chillers

Everyone knows that the classification of chillers is diverse and complex. It is mainly divided into two types: air-cooled chillers and water-cooled chillers. Then subdivided further down. According to the structure, there are open chillers and sealed chillers. According to the classification of compressors, there are screw chillers, scroll chillers, piston chillers, etc. Today I mainly explain the difference between open chillers and water-cooled box chillers.

　　1. Definition of terms: Open chillers and water-cooled box chillers belong to the water-cooled chiller series. Open chillers are mainly composed of compressors, evaporators, condensers, electric control systems, and refrigeration accessories. Water-cooled box chillers are composed of compressors, evaporators, condensers, water pumps, water tanks, electric control systems, and refrigeration accessories. Therefore, it can be seen that the difference between the two is that the water-cooled box chiller can have a built-in water pump and water tank, and vice versa, it is called an open chiller.

　　2. Installation configuration: The chiller is mainly to provide chilled water to products or equipment to achieve the purpose of refrigeration. Both chillers need to be equipped with a cooling water tower for heat dissipation, but because the water-cooled box-type chiller has a water tank and a water pump built-in, when installing, the user only needs to connect the chiller to the cooling water tower and turn on the tap water. use. In addition to the cooling tower, the open-type chiller also needs to add a water pump and a double-layer stainless steel heat preservation water tank before it can be used.

　　3. Analysis of advantages: The water-cooled box-type chiller has a built-in stainless steel water tank and a pipeline water pump. It has a beautiful appearance and a complete configuration. The main components are protected by a steel shell and can be placed in the production workshop. It is simple to install and easy to use/maintain. The open-type chiller does not come with a water tank and a water pump, and can be connected to an external water pump and water tank as required. The advantage is that the volume of the water tank and the pump lift are not limited, which can better meet the needs of different industrial equipment.
