How to choose chillers for small factories

At present, the chiller industry is continuously accelerating the pace of development. More and more different types of chillers have emerged, and many small chiller factories have been born. However, due to the performance and quality of the chillers produced by smaller companies It is unable to fully adapt to the specific use environment requirements of the enterprise, so small factories with less funds must give more consideration when purchasing chillers and control the purchase funds.

　　Professional chiller factory said that small factories can see the quality of the equipment from the three main components of the chiller. The most important one is the compressor, which has become the heart of the unit and the most critical component. A good compressor must not only run stably, but also ensure good energy efficiency.

　　 The evaporator and condenser are also one of the main components of the chiller. The evaporator and the condenser play the role of heat absorption and heat release respectively. Adequate and appropriate heat exchange can give full play to the efficiency of the compressor. If the heat exchange of the condenser is insufficient, it will directly affect the cooling effect of the unit, which is easy in summer. When the high pressure is too high or even the chiller is shut down due to the high pressure exceeding the standard; the heat exchange of the evaporator is more important. Insufficient heat exchange will not only cause low efficiency of the unit, but severely small will prevent the refrigerant from being completely evaporated and return to compression directly The machine caused liquid shock and damaged the compressor, making the entire chiller unusable.

Another main component is the expansion valve. The expansion valve is not only a flow control valve in the chiller refrigeration system, but also a throttle valve in the refrigeration equipment. The main function is to make the high pressure and normal temperature refrigerant liquid flow through the thermal expansion valve. The flow is reduced in pressure, and the wet vapor of low-temperature and low-pressure refrigerant enters the evaporator, vaporizes and absorbs heat in the evaporator, and achieves the purpose of cooling and cooling.

　　Small factories should pay attention to the following three points when purchasing:

1. The choice of the key parts of the chiller. The compressor is the main indicator that affects the performance of the chiller. In the production process, many chiller manufacturers use poorer quality products for the main parts of the compressor to control the overall production cost. Even the use of refurbished compressors has seriously affected the later use efficiency of industrial chillers, resulting in increasing energy consumption.

2. Control the purchase cost. Under the premise of ensuring the main energy of the chiller, purchase the industrial chiller products suitable for yourself with a higher cost performance, which can achieve the purpose of reducing costs, and meet the production needs of the enterprise with less funds. product.

　　 3. Purchasing chillers according to the company's use environment. Water quality and air quality have a certain impact on the operation of the chiller, so you must inform the chiller manufacturer in advance of the water and air quality of your company's location.
