The accurate selection of industrial chillers needs to meet 6 conditions

The accurate selection of industrial chillers needs to meet 6 conditions. When we need to purchase industrial chillers, the selection becomes an important issue for us. If we choose a large one, we will waste material resources, and if we choose a small one, we cannot achieve the ideal cooling. The effect, so how can we accurately choose industrial chillers? Let’s analyze it by Shanghai Kangsai Refrigeration!

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, which is 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 level of the production temperature has extremely important practical significance for the selection of the chiller and the composition of the system. 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 and economic effect of the entire unit, 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 large-scale industrial chillers, the comprehensive utilization of energy should be considered. Because large-scale chillers are equipment that consumes a lot of energy, for large-scale refrigeration stations that provide cooling, full consideration should be given to electricity, heat, and cooling. In order to achieve the best economic effect, it is necessary to pay special attention to the full utilization of waste steam and waste heat.

Condition 4. Environmental protection

When choosing a chiller, environmental protection must be considered to facilitate production, scientific research, and life 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 disasters to mankind.

Condition 5. Vibration

Vibration occurs when the chiller is running, 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 greater 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. .
