With the wide application of the air-cooled chiller, the controversy about the energy consumption of the water cooled chiller is closely followed. Some people believe that the energy consumption of air-cooled chiller is much greater than the energy consumption of the water cooled chiller. But on the annual operation of the comprehensive cost of cold water machine, as well as the maintenance of the point of view, the water chiller was significantly higher. In fact, the East Star feel that the energy generated by the cold water machine, mainly to see the industry needs, how the unit operation, whether the normal maintenance to consider.
First, according to the needs of the industry to choose
Water cooled chiller and air-cooled chiller, each have each characteristic, need to use cold water machine the user according to the different use environment, space, and set the cooling capacity, different urban areas such as to be considered and then be selected.
Two, cold water machine cooling mode
Air-cooled chiller adopts air cooling mode, eliminating the need for cooling water system are essential for the cooling tower, a circulating water pump and a pipeline system, to avoid water poor area caused by fouling in condensers, pipe blockage, saving water resources, is the cold air conditioning equipment products, repair and maintenance of the most economical, simple chiller. Air cooled chiller is more than one time investment to be high, but the annual running cost is lower than that of the water cooled chiller. In addition, the noise of the air cooled chiller is large, the heat emitted from the air is directly distributed to the water cooler, so the operating environment temperature is required, and can only be installed in the outdoor unit.
The chiller must be equipped with cooling tower and a circulating water pump can be used. With respect to the plastic industry, the temperature is not high in the area or the spring and autumn and winter can use cooling tower cooling, so water cooled chillers occupy absolute advantage. But open circulating cooling water system, due to the cooling water after absorbing heat and contact with air, CO2 escape into the air, dissolved oxygen and turbidity increase, easy to cause the corrosion and fouling in cooling water circulation system, the breeding of bacteria and algae and sludge problems, if not water quality treatment could seriously damage the cold water machine, greatly reduce heat exchange efficiency, resulting in energy waste. Therefore, it is very important to carry on the corrosion inhibition, scale inhibition, sterilization and algae removal treatment to the water system.
Three, cold water machine prices
Both the water cooled chiller and the air-cooled chiller can be used in the small power system. Water-cooled chiller on the host to than air-cooled chiller price concessions, but with the cooling tower and a circulating water pump etc., prices have not much less. But in recent years, the central air-conditioning system engineering application of air-cooled chiller, it can be seen, the price is not a problem, the key is to the industry.
Four, unit service life:
The effective service life of the air conditioning system of the air cooled chiller is 5-8 (general air conditioning equipment).
The service life of the water cooled chiller is more than 20 years (water cooled screw chiller).
The service life of the air cooled water chiller is 6-11 years.
Each industry choice of chiller, must according to the actual situation of their own factories to selection, whether it is air-cooled chiller, or water-cooled cold water machine, suitable for their own is the most realistic and the most preferential, of course, if you are unsure of the chiller selection not, directly linked to the East Star Sales staff for you recommend a.
