The development trend of refrigeration equipment affects the price of supermarket refrigerated showcase
The definition of green supermarket refrigerated showcase. The refrigerant of ordinary supermarket refrigerated showcase uses R12 as a foaming agent, Rll, which are all CFC substances with stable performance, non-toxic, non-corrosive and non-combustible. However, studies since the 1970s have shown that CFC substances have a destructive effect on the atmospheric ozone layer. The green supermarket refrigerated showcase is in compliance with environmental protection requirements, and the price of the supermarket refrigerated showcase is also the most reasonable.
Because the power source of supermarket refrigerated showcase is electric energy, and there is no pollution to the atmosphere, its environmental protection requirements refer to the degree of destruction of the ozone layer by the refrigerant and foaming agent and the degree of impact on global warming. It must be zero, or close to zero. The development direction of the green supermarket refrigerated showcase. In the United States, it mainly produces supermarket refrigerated showcases that use R134a as refrigerant and R141b as foaming agent. However, Europe believes that R134a and R141b cannot fully meet environmental protection requirements, and their GWP is still considerable. Therefore, they are more inclined to use R600a instead of R12 and cycloalkane instead of R11. R600a has the best environmental performance, with zero damage to the atmospheric ozone layer and zero greenhouse effect, and its refrigeration performance is better than R12, which can reduce the energy consumption of the compressor by 30-40%, non-toxic and odorless. It can control the possibility of its explosion to less than six parts per million, which is an ideal refrigerant.
my country joined the Montreal Protocol as a developing country in June 1991. According to the agreement, my country will finally phase out ozone-depleting substances in 2010. According to the actual situation in our country, R134a and hydrocarbons are selected as refrigerants in supermarket refrigerated showcase instead of R12: Naphthenic and R141b are selected as blowing agents to replace Rll. At present, most domestic supermarket refrigerated showcase enterprises have taken the lead in adopting alternative technologies to achieve mass production, and various pollution-free double green supermarket refrigerated showcases have been put on the market one after another. BelieveBy 2010, facing consumers in the market will be a new generation of double green supermarket refrigerated showcase. The production of our supermarket refrigerated showcase started in 1956. has developed rapidly since the 1980s. In the mid-1980s, there was the first wave of consumption, with a relatively high share of domestic products, and it was one of the large household appliances that entered the households of the people earlier. However, the average lifespan of supermarket refrigerated showcase in our country is 10 years, and the longest is no more than 15 years. That is to say, when the supermarket refrigerated showcase in the city becomes saturated, the first generation supermarket refrigerated showcase has entered the end of life and needs to be updated. Replacement. According to reports, a new round of supermarket refrigerated showcase consumption climax in my country has arrived. Facing the new demands of the consumer market, major supermarket refrigerated showcase manufacturers have taken corresponding measures to continuously carry out technological innovation and provide the market with a variety of famous and high-quality products. The prices of supermarket refrigerated showcase are relatively more favorable.
