Description
Technical field
The present invention relates to use the heating of solar energy and underground heat, refrigeration system.
Background technology
At present, in correlation technique, comprehensive utilization solar energy and underground heat can carry out constructure heating, refrigeration, can reach the purpose that reduces conventional energy resource consumption, reduces environmental pollution.
But there is the problem of following four aspects in correlation technique.
First, only solar energy system and geothermal system are combined in the system, utilization to solar energy and underground heat in concrete the application separates, for example: use solar energy system to carry out heating by day, use geothermal system to carry out heating at night, or use solar energy system to carry out heating in the winter time, use geothermal system to freeze in summer, in such technical scheme, solar energy and underground heat are not fully utilized, can't effectively, synthetically utilize solar energy and underground heat.
The second, heat accumulation usefulness is low.For example, in the technical scheme that has, with the storage of solar energy that collects to placing underground storage heater, storage heater also absorbs underground heat heat energy simultaneously, hot conversion equipment relies on the heat energy of storing in the storage heater to heat, such technical scheme heat accumulation usefulness is low, only being suitable for the big area of day and night temperature uses, and when using in other area, when the solar energy that collects big, the temperature height, and the soil moisture is when low, solar energy will be lost in the soil, can't realize heat accumulation function effectively, thereby reduce heat accumulation usefulness that visible this technical scheme heat accumulation usefulness is low, regional pertinence is strong, the popularity that does not possess application.In addition, in the technical scheme that has, thermal storage device or storage heater are not set, the heat energy that collects is directly carried out the heat conversion, like this because the unstability of solar energy, when solar energy is sufficient, can waste a part of solar energy, and when solar energy is not enough, can't utilize solar energy fully, will cause the system works instability like this.
The 3rd, collecting efficiency is low, the solar energy contribution rate is low.If adopt independent solar heating, then need heating hot water is heated to the condition that just can possess heating more than 45 degree, again owing to solar energy heating efficient under equal environmental condition and product coolant-temperature gage are inversely proportional to, when the heat collector outlet temperature is more than 45 ℃ the time, with respect to 20 ℃ leaving water temperature, the collecting efficiency of heat collector is low, and it is little that system gets heat, when can't be comprehensively effectively low utilize underground heat heat energy the time, will cause system can't be effectively, steady operation.In addition, when the heat accumulation usefulness of system is low, also can't be for hot conversion equipment provide effective thermal source, thus can't guarantee system stability, work effectively.
The 4th, the collection of underground heat is uneven with the row of returning.For example, in the technical scheme that has, just underground heat is gathered, and do not carry out the row that returns of heat, the heat imbalance of the heat that perhaps collects and the row of returning, when the underground heat that collects when returning row's heat, the underground heat that will cause the underground temperature field disequilibrium, collects reduces gradually, will cause for a long time in the past system can't continuous firing, cause waste.
