The chiller is used for refrigeration, and it will be applied in all aspects of life and work. But do you have an idea of how it works? Different chillers have different refrigeration methods, and their refrigeration principles are also different. Let’s talk about the difference between direct and indirect refrigeration of water-cooled chillers in detail.
The direct refrigeration of water-cooled chiller mainly transports water to the condenser of the chiller through the water pump, cools the condenser, and then returns to the equipment. When the water is sprayed down, the water is cooled down by the fan and then flows back to the bottom basin of the cooling tower, and it runs round and round.
The refrigerant in the condenser liquefies while dissipating heat, and then flows into the evaporator for evaporation, and absorbs heat during evaporation, thereby cooling the tank liquid in the evaporator, and the cooled tank liquid It is transported to the oxidation tank by the water pump, and the cycle is carried out in this way.
The principle of indirect refrigeration of the water-cooled chiller is the same as that of the first half of the direct refrigeration, except that the cooled water is also transported to the heat exchanger through the water pump. Water, with sulfuric acid on one side. Then, the sulfuric acid is cooled down through the process of heat transfer, and a cycle process is also completed.
Since the indirect freezing method is not easy to corrode the chiller, the service life of the equipment is also longer than that of direct freezing, so it has advantages.
