Falling film chillers have attracted much attention in the refrigeration industry due to their high efficiency and energy efficiency. The energy efficiency performance of falling film chillers will be discussed in detail from several aspects. 1、 Energy efficiency definition and standard energy efficiency usually refer to the measurement of electric energy or other energy consumed by equipment to complete unit cooling capacity under specific working conditions. For chillers, the main measure of energy efficiency is the coefficient of performance (COP), that is, the ratio of refrigerating capacity to input power. The higher the COP value, the better the energy efficiency of the unit and the lower the energy consumption. 2、 High efficiency of falling film chiller 1. High heat exchange efficiency chiller uses falling film evaporator, which forms refrigerant liquid film on the surface of special falling film evaporation tube through spray technology for film evaporation. Compared with other types of

The fluorite/anhydrous hydrogen fluoride fluorite market is waiting and finishing. The demand performance is poor, the market procurement is cautious, the wait-and-see atmosphere is strong, the market supply side still has good support, and the quotations of major enterprises are temporarily stable. The anhydrous hydrogen fluoride market operates weakly and stably, and the on-site enterprise devices operate at low load, mainly to deliver mainstream contracts. However, due to the weak terminal demand, the mentality of the industry is still empty. The chloride and chloride market is in shock. The market price of raw liquid chlorine rose narrowly last week and then fell again, with limited cost support; The inventory of tetrachloroethylene plant is low, and some offers were raised last weekend. At present, the price is stable; Most other products also remained stable, and the market just needed to clinch deals. It is expected that the short-term chloride market will operate in a range of shocks. Market price of refrigerant

Honeywell announced that Wal Mart China will use Honeywell high-efficiency energy-saving refrigerant Solstice in the refrigeration system of its 26 stores ® N40（R448A）。 Honeywell is conducting business around the three major trends of energy transformation, automation and future aviation. This cooperation is just an example of Honeywell helping the industry to achieve energy transformation. Honeywell Solstice ® Compared with R404A, the refrigerant commonly used in retail stores and convenience stores ® N40 (R448A): 1. The global warming potential (GWP) is 1273, reducing by nearly 70% 2. The energy efficiency of commercial refrigeration systems is improved by 5% - 10% 13. It can be directly replaced by the existing
