How to choose a chiller
The chiller is a widely used equipment in industrial production and commercial places. Its main function is to cool down. Like the central air conditioner in shopping malls, which we often see in our lives, its core component is the chiller. Today I will talk about what the chiller is divided into and how to choose.
First of all, in terms of his refrigeration form, chiller can be divided into water-cooled chiller and air-cooled chiller.
The air-cooled chiller uses the shell and tube evaporator to exchange water with the refrigerant. The refrigerant system absorbs the heat load in the water, cools the water to produce cold water, and brings the heat to the fin condenser through the role of the compressor. It is then dissipated into the outside air by the cooling fan.
The water-cooled chiller uses a shell and tube evaporator to exchange heat with the refrigerant. The refrigerant system absorbs the heat load in the water, cools the water to produce cold water, and brings the heat to the shell and tube condenser through the role of the compressor. The refrigerant exchanges heat with water, so that the water absorbs the heat and then dissipates the heat out of the external cooling tower through the water pipe.
In fact, the difference between these two types of chiller is that the cooling method is different. The home air conditioners we see in our daily life are typical air-cooled machines. First of all, the advantages of air coolers are generally relatively small, and do not need cooling towers, are used in places with small cooling capacity requirements, but a particularly big disadvantage of air coolers is the harsh requirements of the use environment, and the environment Changes have a greater impact on air-cooled machines. The advantage of the water cooler is the large cooling capacity, and because the water cooling is used, the cooling tower has little effect on the environment, and the stability is good. The disadvantage is that it needs to build a cooling tower, which requires a longer construction time and flexibility. Almost. Generally, air-cooled chiller is used in places with small area and small cooling capacity, such as small shopping malls and villas. Water-cooled water chiller is used in places with large area and large demand for cooling capacity, such as production lines or large production workshops that require a large amount of frozen water.
