Description
Technical field
The invention belongs to soil source and technical field of solar utilization technique, be specifically related to a kind of soil source heat pump, solar association heat-storing heating system.
Background technology
The soil source heat pump technology utilizes earth surface geothermal using resource to carry out power conversion as Cooling and Heat Source, and shallow surface is a huge solar thermal collector, collected 47% solar energy, be equivalent to utilize human every year more than 500 times of energy, and be not subjected to the restrictions such as region, resource, really be have a large capacity and a wide range, ubiquitous.This is to be stored in shallow surface to be close to unlimited regenerative resource, also is clean energy resource.Compare with surrounding air on the ground, the 5m following soil moisture in ground is annual basicly stable and a little less than average temperature of the whole year, and relatively low condensation temperature and higher evaporating temperature can be provided in winter in summer respectively.So on thermodynamic principles, soil is a kind of Cooling and Heat Source than the better heat pump of surrounding air.And soil source heat pump system can row people atmospheric environments such as heat, steam and bacteriums, not meet the strategic requirement of current sustainable development.Usually soil source heat pump consumes the energy of lKW, and the user can obtain 4KW above heat or cold, and this additional energy is exactly the energy from soil.In addition, energy temperature more constant characteristic in ground so that the source pump operation is more reliable, stable, has also guaranteed high efficiency and the economy of system.Estimate that according to the EPA of Environmental Protection Agency the soil source heat pump that design and installation is good can be saved the operating cost of user 30%～40% heating and refrigerating air-conditioning on average.Efficient ground source heat pump, the cold of average generation 1 standard ton only needs the power consumption of 0.88kW, and its power consumption only adds 30%～60% of steam generator system for common handpiece Water Chilling Units;
Solar thermal utilization mainly is divided in the middle cryogenic applications of solar energy and the solar energy high temperature and uses.From the present situation of solar thermal utilization industry, high temperature is used and is at present research and development and Demonstration And Extension stage in the solar energy, has good market prospects future; The solar water heater industry, closely related because of itself and the people's daily life, product has environmental protection, energy-conservation, safety, economic dispatch typical feature, develops " main force " that become China's solar thermal utilization rapidly.
At present, China has become maximum in the world solar energy optical-thermal application market, also is maximum in the world solar thermal collector manufacturing center.The solar thermal utilization industry was produced 8,000,000 in vacuum tube in 2011, and totally 5,760 ten thousand square metres of solar energy vacuum tube and flat water heaters increased by 17.6% than 2010, and total recoverable amount is 21,740 ten thousand square metres.
Day by day perfect along with the exploitation of middle high-temperature solar water heater and building integration technology, the application of solar water heater no longer is confined to provide hot water, just progressively expand to heating, refrigeration, oven dry and commercial Application direction, market potential is huge.
In recent years, the Housing Guarantee of country's release, new forms of energy building Demonstration Application, new rural urbanization construction and upgrading open new development space will for the solar thermal utilization industry.And national energy-saving reduces discharging the policy makings such as strategy and enforcement, all will greatly promote the development of solar thermal utilization industry.Solar energy and building (comprising high level) Study on Integration and enforcement are the important directions that following solar energy development utilizes, and also are that whole solar energy industry is done large basic place.
At present, application and the application of solar energy system in heating system in heating system all carried out separately in field separately with research for soil source heat pump system, focus mainly is to solve the thermal balance that can't realize soil source in summer in winter for heat problem with soil source heat pump system separately, since soil source heat pump with the earth as the heat absorption, the heat release carrier, therefore need winter consistent to the heat balance that the earth discharges with summer from the heat of the earth absorption, only in this way soil source heat pump could long-term normal stable operation.But the northern area winter heating cycle is longer than far away and freezes the cycle summer, because building, all need heating winter simultaneously, but need freeze building summer then seldom, therefore cause the building of employing soil source heat pump heating along with the serious imbalance of heat absorption heat release, cause ground temperature to descend year by year and finally can't carry out normal heating.Can't realize must supplying under the extreme weather heat problem and solve for heat problem with solar energy system, reason is that solar energy heating efficient sharply descends under the coldest in the winter time extreme weather.Thereby this two kinds of heat-supplying mode application have in practice been limited.Through domestic and international many researchers' effort, although obtained some theoretical results and correlation technique at both aspects such as combination complementation.Yet, because soil source heat pump and solar association accumulation of heat still are in the exploratory stage, still have many technical barriers to need to solve, as how realizing geothermometry, controlling accumulation of heat etc.Therefore, to the further further investigation of the problems referred to above and solve Related Technical Issues, the progress of soil source heat pump, solar association accumulation of heat heating technology there is positive realistic meaning.
