Abstract
A seasonable heat-accumulated heat supply system belongs to the field of heat supply. According to the seasonable heat-accumulated heat supply system, an air source heat pump and heat tube compound type heat supplementing device is adopted to supplement heat to a heat accumulator in summer with higher external temperature and transition seasons; an absorbed heat pump acquires heat from the heat accumulator in winter for supplying heat to users; and when the temperature of the heat accumulator is lower, the heat accumulator is preheated by a heat supplementing device and then enters an evaporator of the absorbed heat pump for combined heat supply. In addition, a direct heat supply mode of a boiler or an air source heat pump can be realized, and thus the guarantee rate of heat supply can be improved. The utility model is technically characterized in that the present absorbed heat pump system is connected with the heat accumulator and the air source heat pump and heat tube compound type heat supplementing device, and thus the seasonal transfer of summer heat to winter heat can be realized, the source path of a low-grade source of the heat supply system is enlarged, the heat island effect in summer is relieved, the heat for heating in winter is doubled and the remarkable energy-saving effect is achieved.
Description
Technical field
The utility model relates to a kind of heating system of seasonal accumulation of heat, is specially adapted to ambient temperature height in summer, winter temperature is low, and concentrated hot water demand's area is arranged, and belongs to the heat supply heating field.
Background technology
Along with the raising of rapid economy development and living standards of the people, people also constantly increase the demand of domestic hot-water and heating hot water.Statistics shows that the ratio of China building energy consumption account society total energy consumption is between 22%～25%, and wherein about 40% is used for building and heating, and area, northern cities and towns adopts the energy consumption of heat supply network central heating or sub-district central heating to account for 60% of building heating energy consumption.Along with growth in the living standard, the many newly-built communities in the Yangtze river basin also begin to adopt central heating at present, and a lot of cities are also at the extensive central heating net of planning.As seen, there is the region of central heating demand more and more wider.In addition, the quick increase of construction area, the heating demand also can increase substantially thereupon, and these all make the energy-saving and emission-reduction pressure of country grow with each passing day.
Present heat supply is normally burnt low-temperature water heating (60～90 ℃) with the boiler combustion fossil fuel and is directly supplied with user heating, or utilize heating plant will concentrate the hot water about 130 ℃ in the heat supply network (primary side hot water) to convert low-temperature water heating (secondary side hot water) to resupply user heating, though the heat total amount before and after the heat exchange does not change, but the utilisable energy that the heat exchange link causes loss is but very big, its heating efficiency is always less than 1.0, under long-play, cause a large amount of heating energy consumptions.
And other heating equipments are such as heat pump etc., and from low-grade energy side-draw heat, though its efficient increases, but still what adopt is real-time heat supply mode.No matter being air source or soil source water source etc. promptly, all is heat-obtaining from current low temperature environment.When heat pump during directly to the air heat-obtaining, winter, ambient temperature was lower, and the temperature fluctuation amplitude is big, and device efficiency is lower, and the winter air source heat pump evaporation to send out device frosting problem also be further to improve a big technical barrier of air source heat pump efficient.Based on this, winter, the soil moisture was higher than temperature and the relatively stable favor that once had been subjected to everybody, yet thermal source is not inexhaustible renewable resource, heat pump will certainly cause the decline year by year of the soil moisture throughout the year from underground extraction heat, thereby cause the decay significantly of unit performance, even can't normally move at all.
