Description
Technical field
The invention belongs to refrigerated air-conditioning system design and fabrication technology field, relate to the heat source tower device that a kind of deficiency for common heat source tower improves and utilize solar energy to realize regeneration of waste liquor。
Background technology
Raising along with socioeconomic fast development and living standards of the people; energy consumption of air conditioning system in buildings is more and more higher, and the contradiction between demand and supply of energy, for alleviating energy crisis; realize social sustainable development, air conditioning system and equipment to develop towards green energy conservation direction。
The hot-summer and cold-winter area being in the Yangtze river basin is hot for summer, and winter is clammy, and climatic environment is severe。This regional population is numerous simultaneously, economically developed, requires higher to indoor environment, therefore energy consumption is huge。High-efficiency environment friendly ground solves the air conditioner cold-heat source problem of hot-summer and cold-winter area to reducing China's energy consumption, promotes that the sustainable development of economic society has great significance。
The Air Conditioning Cold that hot-summer and cold-winter area is commonly used at present mainly has: handpiece Water Chilling Units+boiler, net for air-source heat pump units and water earth source heat pump etc.。But they all also exist some problems in actual use: during handpiece Water Chilling Units+boiler scheme heat supply in the winter time, handpiece Water Chilling Units is left unused, and utilization rate of equipment and installations is low；And the burning of boiler, can serve row environmental problem by band, and a lot of cities are prohibited。Air source heat pump is inefficient when cooling in summer, needs to solve frosting problem during winter heating, and heating efficiency is low。Although water earth source heat pump scheme system energy efficiency is high, but the restriction by geographical geological conditions is relatively big, and initial cost is high, it is impossible to spread。
When traditional cold heat source plan has many deficiencies, heat source tower heat pump system is arisen at the historic moment。It is according to China's hot-summer and cold-winter area specific weather condition design, on the basis of the cold handpiece Water Chilling Units of original list, cancel the auxiliary thermal sources such as boiler, summer is as cooling tower, winter absorbs the low-grade heat source in air by heat source tower, is solved the demand of building cooling in summer, heat supply in winter by a set of unit simultaneously。Heat source tower heat pump system efficiently solves tradition, and air-cooled heat pump cooling in summer operational efficiency is low, the problem of the easy frosting of Winter heat supply heat exchanger。Than handpiece Water Chilling Units+boiler scheme, its investment of equipment is less, utilization rate of equipment and installations is higher。And contrast and water earth source heat pump, its initial cost is little, and operating cost is low, and is not limited by geological conditions。Additionally, heat source tower heat pump system equipment arrange with take up room on identical with conventional water cooled chiller, transformation is convenient, has very big application potential in building energy-saving renovation engineering。The novel building cold heat source plan of a kind of great development prospect of heat source tower heat pump scheme as can be seen here。
The capital equipment of heat source tower heat pump is heat source tower, and heat source tower according to whether being divided into main open type and enclosed two kinds with air contact, and two kinds of heat source towers cut both ways when the summer in winter uses。Open type heat source tower directly contacts with air, and heat exchange efficiency is high, and summer is effective, but during winter operation, the steam in air can enter in solution, makes solution dilution, causes freeze point depression, brings hidden danger to the safe operation of system。And closed type heat source carries out heat exchange by heat exchange fin and air, it is absent from solution dilution problem during winter operation, but due to indirect heat exchange, heat exchange efficiency is not high, be only applicable to use in winter。In addition time in order to prevent winter temperature lower than 0 DEG C, heat exchange fin affects its heat exchange efficiency because of frosting, and closed type heat source tower needs when running to spray anti-icing fluid, also needs to anti-icing fluid is regenerated after running a period of time。Conventional renovation process can expend substantial amounts of energy, reduces the operational efficiency of unit。Therefore, how to take into account the high heat exchange efficiency in open type heat source tower summer stable with the freezing point in closed type heat source tower winter, and improving the heat exchange efficiency of closed type heat source tower when running in the winter time, low energy consumption must solve the regeneration issues of anti-icing fluid, popularization and extensive utilization for heat source tower have great significance。
