Description
Technical field
The present invention relates to heat energy utilization, belong to renewable energy utilization, particularly realization building heating, the refrigeration of the complementation of solar and superficial layer face of land heat energy.
Background technology
How low-grade energy effectively utilizes, existing Technology Need is utilizing traditional energy, low-grade energy is promoted, again low-grade energy is used, but this mode of utilizing all needs to consume traditional energy, as source, various ground and water source heat pump technology, need electric energy further to replenish, it is used.
Temperature control technology for building has a variety of, prior art mainly adopts the form that consumes a kind of energy, the temperature control that realizes building, the compression refrigeration technology of main consumed power, and other traditional energies of consumption of later stage development as the combustion gas Refrigeration Technique, mainly adopt fan coil and radiator at its end-equipment, and at present also utilize heating and the refrigeration of various pipelines for terminal device what adopt.Various absorptions and adsorptive refrigeration technology have also appearred in the appearance of solar energy acquisition technology, but these technology all include a kind of refrigeration plant at least, need to consume the temperature control that traditional energy could be realized building.
The existing system that relies on air conditioner refrigerating and boiler heating, the heating supply and return water temperature gets 95/70, air conditioning water gets 7/12, air conditioning hot gets 60/50, because air-conditioning is forced-convection heat transfer, so it does not need the excessive endways temperature difference, heating installation adopts 95/70, reason is that end does not have forced convertion, and chilled water must be set in below the apparatus dew point, and this just requires chilled water generally will be controlled under 12 degree.But water will freeze below 0 degree, can not be lower than 5 degree so set low temperature, has artificially stipulated 7/12 degree.Thereby the temperature difference of 5 degree are only arranged the time in refrigeration.Under summer worker's frame, indoor air temperature 25 degree, then the temperature difference of water and air is about 15 degree.And winter air temperature 18 degree, water is walked 60/50 operating mode, and the temperature difference of water and air is about 37 degree.Can not think that the wind dish exchange capability of heat in winter almost is the twice in summer so do not consider wet cooling condition.Therefore, from wind dish angle, to walk 30/25 such operating mode also be feasible to water when the most extreme.If adopt traditional boiler heat supplying, the ignition temperature of boiler own is looked different fuel and difference about the 500-1500 degree.Therefore if heat hot water about 40 degree with the flue gases of nearly thousand degree, heat exchange efficiency is too low, and the ability of boiler is wasted greatly, and this is uneconomic, designs according to 60/50 such operating mode usually.This has been the lowest limit of hot-water boiler, does not in most cases also accomplish, also will add heat exchanger.Such temperature also can be prevented antipriming pipe and equipment scaling simultaneously.The temperature difference of the end of existing system fan coil can realize the temperature-difference refrigerating and the heating of 15 degree, but because thermal source adopts the gap between boiler and the air-conditioning, caused and generally adopted high temperature difference to heat at present, owing to must adopt the heating of high temperature thereby the use radiator occur and carry out heat supply in winter, in fact, if adopt the blower fan heating, its exchange capability of heat can heat in the 15 degree temperature difference, if the indoor temperature that requires according to GB reaches 18 degree like this, adopt the water of 23 degree promptly can realize the heating in winter in the winter time, thereby provide the possibility of technology for utilizing regenerative resource directly to heat.
Development along with end technology, the energy source temperature that heating and refrigeration need and the temperature difference of environment temperature are more and more littler, as adopt traditional radiator to need the thermal source heated of 80-90 degree, after adopting the floor heating technology, the temperature of thermal source can be reduced to 40-60 degree, this makes solar heating become possibility, the capillary that later stage occurs, its heating temperature is 30-40 degree, its cryogenic temperature can adopt 10-20 degree, and the low-temperature receiver of traditional fan coil Technology Need 3-10 degree just may guarantee the cooling of building effect.The appearance of this end technology makes and directly utilizes low grade heat energy to become possibility.On the shallow layer surface heat energy utilization, the degree of depth of existing perpendicularly buried pipe is 60-100 meters, and this degree of depth is suitable for existing heat pump techniques, but because its temperature is in the scope of 15-20 degree substantially, can't be directly used in heating.
The appearance of new end-equipment makes provides the mode of the energy also can change, and must consume heating and the refrigeration that traditional energy can realize utilizing regenerative resource realization building till now by traditional.But solar absorption or the absorption type refrigerating that adopts all needs refrigeration unit at present, high and the conversion inefficiency of the present price of this equipment, absorb or adsorptive refrigeration technology as adopting for the thermal source that is lower than 100 degree, its COP value is 0.4-0.8, so also Lang Fei a large amount of heat energy, the technology that makes can't generally be promoted the use of.
Summary of the invention
Purpose of the present invention just provides the complementary building energy of a kind of solar and superficial layer face of land heat energy and utilizes system, does not need to consume traditional energy, just can realize low-grade heat source directly is used in building heating and refrigeration.This system is delivered directly to end with satisfactory low-grade energy, realize the direct utilization of low-grade energy, further can adopt a heat exchanger and low-grade energy to carry out correct heat exchange, reach the requirement of the temperature of default, utilize a kind of heat-transfer fluid that heat energy is transported to end-equipment then, end-equipment discharges heat energy, thereby realizes the direct utilization of low grade heat energy.This system adopts the temperature difference of spending with target temperature 5-15 to heat and freezes, and summer, low-temperature receiver was 11-21 degree, and winter, thermal source was 21-41 degree, realized the temperature of indoor 16-26 degree is controlled.Can directly utilize temperature like this is the low-grade heat source of 0-45 degree, realizes the direct heating and the refrigeration of building.In heating and process of refrigerastion, when if shallow layer surface heat energy can not provide the energy of composite demand, adopt solar energy to replenish, adopt solar refrigeration as a supplement in summer, adopt the heat energy of solar thermal utilization to replenish in the winter time, mainly adopt the main energy that is of shallow layer surface heat energy in summer, solar refrigeration is for replenishing, in the winter time based on shallow layer surface heat energy, solar energy is for replenishing, or is that main energy sources shallow layer surface heat energy is for replenishing with solar energy, but specifically how to carry out, need be according to geological condition, the pipe laying expense, the solar thermal utilization cost is taken all factors into consideration.Certainly the thermal source of higher temperature and more the low-temperature receiver of low temperature can directly utilize more, still be suitable for the present invention, but emphasis of the present invention is to adopt low-grade energy directly to heat and freeze.
