What are the advantages and disadvantages of different types of chillers?
When it comes to chillers, you will find that there are many names of chillers, complex and diverse, but they are mainly divided into the following situations, as far as heat dissipation is concerned, they are divided into water-cooled chillers and air-cooled chillers. According to the different compressors, it can be divided into scroll chiller, screw chiller, centrifugal chiller and piston chiller. According to the different structures, there are open chillers and sealed chillers. Today, we will mainly talk about what is the difference between open chiller and water cooler chiller?
1. Definition of noun: Open chiller and water cooled box chiller belong to the water-cooled chiller series. Open chillers are mainly composed of compressors, evaporators, condensers, electrical control systems and refrigeration accessories. The water-cooled box chiller consists of compressor, evaporator, condenser, pump, water tank, electrical control system 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 cold water to the product or equipment to achieve the purpose of refrigeration. Both chillers need to be equipped with cooling water towers to dissipate heat, but since the water-cooled box chiller has a built-in water tank and water pump, when installing, users only need to connect the chiller to the cooling water tower and turn on the tap water. The open chiller also needs to add a water pump and a double-layer stainless steel insulation water tank.
3. Advantage analysis: The water-cooled box chiller has a built-in stainless steel water tank and pipeline pump. It has a beautiful appearance and a perfect configuration. The main components are protected by a steel shell and can be placed in the production hall. It is easy to install and easy to use/maintain. Open chillers do not have their own tanks and pumps and can be connected to external pumps and tanks as needed. The advantage is that the head of the tank and pump is not limited, which can better meet the needs of different industrial equipment.
In the circulation system of the refrigerator, the compressor inhales low-temperature and low-pressure refrigerant steam from the evaporator, which is adiabatically compressed by the compressor into high-temperature and high-pressure superheated steam, and then pressed into the condenser for constant pressure cooling, and heat is released to the cooling medium, and then cooled into a supercooled liquid refrigerant.
