Air-cooled screw chiller points of note:
1, screw chiller temperature range when choosing an industrial chiller/freezer, the first thing you should consider is the temperature requirements of the plant. The level of temperature produced has extremely important practical significance for the selection of chillers and system components. For example, chillers used for air conditioning and chillers used for low-temperature projects, there is often a fundamental difference.
2, the chiller energy consumption refers to the electricity and steam consumption. In particular, the choice of large industrial chillers, chillers, should take into account the comprehensive use of energy, because large ice and water machine when a large energy-consuming equipment, so for the supply of cold large refrigeration station, should be fully considered to the comprehensive use of electricity, heat, cold and balance, especially to note the full use of waste steam, waste heat, with a view to achieving the best economic results.
3, chiller refrigeration and the size of the individual refrigeration chiller cooling capacity is directly related to the energy consumption of the entire unit and the economic effect of operation, which is worth paying attention to. Especially in the design of the cold station, in general, do not set up a single chiller, which is mainly to consider when a chiller failure or shutdown for maintenance, not to stop production, but should be combined with the production situation, selected a reasonable number of units. Chiller cooling water quality is good or bad, the impact on the heat exchanger is greater, its role in endangering the equipment is scaling and corrosion, which will not only affect the chiller cooling capacity reduction, and will seriously lead to blockage and breakage of the heat exchanger tube.
4, air-cooled screw chiller operation will produce vibration, but the frequency and amplitude size vary greatly depending on the type of unit. If there is a requirement for vibration prevention, the chiller with smaller amplitude should be used, or the foundation and piping of the chiller should be damped. Chiller environmental protection. When selecting a chiller, environmental protection must be taken into account to benefit production, scientific research and living requirements. For example, the following should be paid attention to: industrial chillers, chillers will occur when running noise, noise value is increased or decreased with the size of the chiller; also some chillers used in the refrigerant has a toxic, irritating taste, combustibility and explosive; more some refrigerants will destroy the ozone layer in the atmosphere, to a certain extent, will bring disaster to mankind.
