Cooling water temperature influence on the refrigerating capacity of the industrial water chillers, in terms of cost, in refrigeration compressor revolutions, as well as the evaporation temperature, under the condition of industrial water chiller condensing temperature is lower, the greater the refrigeration coefficient, the less the power consumption.

according to the calculation, industrial water industrial ice machine condensing temperature increase 1 ℃, the refrigerating capacity of the unit power consumption is about 3% up 4%. So keep the condensation temperature stability to improve the refrigerating capacity of the industrial water chiller is very good.

if you keep the condensation temperature stability of the industrial water chiller, need to take the following measures: to increase the amount of water in the heat exchange area of the condenser and the cooling water; Or to improve the heat transfer coefficient of condenser, but, for a cooling air conditioning system, increase the area of the condenser is almost impossible. Increase the amount of water is bound to increase water in the condenser cooling water flow, this will affect the service life of industrial water chillers, but also increases the power consumption of cooling water pump and the pipe material waste and a series of problems, and the effect is not ideal. Increase cooling tower model, consider a certain amount of surplus coefficient is fair, but if blindly increase the type of cooling tower, in pursuit of lower cooling water temperature is not worth the cost, and the cooling water temperature is limited by the local meteorological parameters. To improve the heat emission coefficient of the condenser cooling water side, it is practical and effective, and improve the heating system is the effective ways to reduce water side fouling resistance, effective treatment of cooling water filling water. Most at the moment, the air conditioning cooling system for the open loop system, its effect is good, low cost, is widely used in engineering, but after evaporation cooling enrichment, various ions in water, dissolved solids and suspended solids increase, coupled with the air and water contact, increase oxygen and so on can cause equipment and pipeline corrosion perforation was down. Therefore, the author thinks that, there are several factors influence the refrigerating capacity of the industrial water industrial ice machine.
