The steam is transformed into cool breeze. Some districts in the provincial capital test water for "hot refrigeration".
July 15th news (reporter Wang Guangzhao Intern Xu Zhuo) hot steam at 200 c can also become cool breeze. Reporter 15 from the Ji'nan ThermoElectron Corporation to understand that the use of high temperature steam refrigeration is taking the lead in some large enterprises, agency units and individual communities "taste the fresh".
8, the reporter came to Ji'nan thermal power, just entered the steam refrigeration studio, the heat wave came to us. Ji'nan thermal power related to the person in charge, the annual summer capital of the city is very large, power generation will produce a lot of waste heat, if you do not want to use it, it will be wasted. The residual heat generated by power generation can be transformed into a cool breeze with a minimum temperature of 8 degrees Celsius through a lithium bromide steam refrigerator. The steam at 200 c can be transformed into a cool breeze with a minimum temperature of about 8 C.
Shun Jade Garden District is the small area of the provincial capital to realize steam refrigeration, which has more than 300 residents with an area of more than 40000 square meters, and all use steam refrigeration in the area. Wang Yucheng, the manager of the after-sales service department, told the reporter that they had installed a 1 million big card of lithium bromide refrigeration unit to the district. There was a large central air conditioner in the equipment. The fan coil in each household was the terminal receiving device of the equipment, and the steam was used to refrigerate in summer.
Xu Congxia, the technical director of the the Great Wall air conditioning company, gave the reporter such an account. Taking Shun Yu Garden District as an example, the power consumption of the ordinary electric refrigeration air conditioning is 560 kW / hour. The steam consumption of the unit is 2500 kilograms per hour, and the cost is 560 according to the current commercial electricity price and steam price. Yuan / hour and 445 yuan / hour, so the cost of steam cooling is 115 yuan less than that of electric refrigeration.
"don't underestimate this steam refrigeration. Compared with ordinary electric air conditioning, steam centralized refrigeration has many advantages." Ji'nan thermal power group, the responsible person, the steam cooling comfort is high, the room people can enjoy the natural cool, compared with the ordinary air conditioning, it has the advantages of fresh air, uniform cold air, suitable humidity and so on.
"the use of high temperature steam refrigeration, starting from 2005, to the present only a few large organization units, there has been no large-scale promotion." The person in charge said that the pipe network used by steam refrigeration is basically the same as the heating network in winter. It is mainly the high price of lithium bromide refrigerant, at least a few million, and the steam passes through the transformation of the cool wind. At present, many residential areas have no opening conditions, only a dozen large enterprises, unit units and individual residential quarters. With corresponding equipment, steam refrigeration has begun to take place.
