What type heat exchangers are there in chiller?
What types of heat exchangers are there in chillers? Condenser: is a heat exchanger that transfers heat from a refrigerant gas to an external cooling source, such as water or air, causing the gas to condense into a liquid. This process releases latent heat from the substance and rejects it into the surrounding environment. Evaporator: the refrigeration device of chiller output cooling capacity through evaporator. The heat of cooled medium is absorbed by refrigeration liquid vapor in evaporator. According to the different cooling medium, the evaporator can be divided into cooling liquid evaporator and cooling air evaporator etc., Ice water machine：it is to make temp airflow alternate through a container with filler, utilizing filler as medium to transfer heat air to cold airflow. Reversing heat exchanger：It’s use in air separation device to exchange heat for air with nitrogen, nitrogen and oxygen etc., and the unit is freezing and clearing moisture and carbonate dioxide from air, to replace the cold storage role. Dry type heat exchanger: the refrigerant is vaporizing in the copper and absorbing heat of water on pipes surface to produce chilled water. Flooded evaporator: it is different from dry type heat exchanger what refrigerant on copper pipes surface to evaporating and absorbing, the copper pipes immersed in the refrigerant, flooded type with high efficiency, but need to filling a large amount of refrigerant while Falling-film type evaporator: it is same with flooded evaporator that water inside the pipe with coolant outside. But the difference is that the coolant spray on copper through spray thrower while can improve heat exchange efficiency, furthermore, it’s no need so much coolant, only need to ensure the coolant could support that there is a liquid film covering on evaporation pipe, unlike flooded type evaporator which required the copper pipe immersed in the refrigerant. Therefore, we have simple tips and solution for selecting a heat exchanger. After clearly understanding the machinery to be used, we can look at our configuration and analyze and understand the configuration to know our choice. The heat exchanger is an essential part of the chiller machinery, DANNICE can provide you a tailor-made solution as customer requires to design heat exchanger. When customer in doubt, DANNICE give you a better answer and appropriate solution with 100% commitment spirit to do the best.
