Accurate selection of industrial chillers needs to meet 6 conditions

The accurate selection of industrial chillers needs to meet six conditions. When we need to purchase industrial chillers, the selection becomes an important issue for us. If we choose a large one, it will waste material resources, and if we choose a small one, it will not achieve the ideal cooling. Effect, then how can we accurately choose industrial chillers?

　　There are many kinds of refrigeration equipment in daily use, but the application range of chillers is relatively wide. It can control the temperature within a specific range, and the refrigeration effect is stable, suitable for use in various industries.

　　 According to different industries, the demand for industrial chillers is different. When selecting the type of chiller, we can select the type according to the following six elements.

　　Condition 1, temperature range

　　 When choosing an industrial chiller, the factory's requirements for the production temperature should be considered first. The production temperature has extremely important practical significance for the selection of chiller and system composition. For example, there are often fundamental differences between chillers used for air conditioning and chillers used for low-temperature engineering.

　　Condition 2, refrigeration and single cooling capacity

　　 The cooling capacity of the chiller is directly related to the energy consumption of the entire unit and the economic effect of operation, which is worthy of attention. Especially when designing a cold station, under normal circumstances, there is no single chiller. This is mainly to consider that when a chiller fails or shuts down for maintenance, it will not stop production. Instead, a reasonable unit should be selected based on the production situation. Number of units.

　　Condition 3. Energy consumption

　　 Energy consumption refers to electricity consumption and steam consumption. Especially when choosing a large industrial chiller, the comprehensive utilization of energy should be considered. Because a large chiller is a device that consumes a lot of energy, for a large-scale refrigeration station that provides cooling, full consideration should be given to electricity, heat, and cooling. The comprehensive utilization and balance of waste steam and waste heat should be paid special attention to in order to achieve the best economic effect.

　　Condition 4. Environmental protection

　　When choosing a water chiller, environmental protection must be considered to facilitate production, scientific research and living requirements. For example, the following should be paid attention to: noise occurs when the chiller is running, and the noise value increases or decreases with the size of the chiller; some refrigerants used in the chiller are toxic, irritating, flammable and explosive; some refrigeration The agent will destroy the ozone layer in the atmosphere, and when it reaches a certain level, it will bring disaster to mankind.

　　Condition 5, vibration

　　 When the chiller is running, it will produce vibration, but the frequency and amplitude vary greatly depending on the type of unit. If there is a requirement for anti-vibration, a chiller with a smaller amplitude should be selected, or the foundation and pipeline of the chiller should be damped.

　　Condition 6, the quality of cooling water

The quality of the cooling water has a great impact on the heat exchanger. The effect of endangering the equipment is scaling and corrosion. This will not only affect the reduction of the chiller's cooling capacity, but also cause blockage and damage to the heat exchange tube in severe cases. .
