Using the water of the heat of transformation, earth-source hot-pump system and refrigeration with heating technique
Technical field
The invention belongs to heat pump heat supply and refrigeration technology field, more particularly to a kind of water, the earth source heat pump of the utilization heat of transformation System and refrigeration are with heating technique.
Background technology
Water, ground source heat pump technology occur relatively early, using also comparative maturity abroad.Opened from generation twentieth century 30 or 40 years Begin, occurred as soon as successful engineer applied case.At present, in American-European, Japan, the application of surface water heat pump system is more universal, Achieve considerable energy-conservation and emission reduction effect.
China's heat pump techniques develop comparatively fast in recent years, and the especially hot and cold system of underground water and soil has obtained substantial amounts of work Cheng Yingyong, because municipal sewage temperature is higher than natural water temperature, so that sewage source heat pump system has obtained very fast development.And Surface water heat pump System Development relatively lags behind, the surface water capacity for being primarily due to surface water heat pump system needs is very big, temperature compared with It is high(It is general in more than 5 DEG C of freezing point temperature), in fact, it is possible to which the water body for meeting this use requirement is not a lot, especially in the winter time The cold north, it is relatively low in Heating Period surface water water temperature, it is partially narrow using the water body temperature difference(General 5 DEG C or so), and require heat exchange Front and rear temperature is higher than freezing point.
Therefore, how under the premise of surface water can utilize the temperature difference less, extraction surface water heat as much as possible is water Source heat pump can be fast-developing bottleneck.
The content of the invention
In view of the deficienciess of the prior art, the present invention provides a kind of water, earth-source hot-pump system and the system of the utilization heat of transformation It is cold with heating technique, both using water body temperature drop sensible heat, while using the solid heat of transformation of water-setting, the heat of same temperature extraction surpasses Cross prior art more than 15 times, break the restriction of water source heat pump system freezing point.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is:Using the water of the heat of transformation, earth-source hot-pump system, Heat exchanger group, source pump and indoor end system including being arranged in water surface bottom, in addition to anti-icing fluid storage tank and buffered water Case, the heat exchanger group is arranged in surface water body bottom and soil contact position, and the heat exchanger group connects anti-icing fluid storage tank respectively And source pump, indoor end system is connected by buffer tank with source pump, between indoor end system and buffer tank Provided with first circulation water pump group, second circulation water pump group, source pump and anti-icing fluid storage are set between buffer tank and pump heat engine group The 3rd recirculated water pump group is set between case, heat exchanger group passes the sensible heat and the heat of transformation of water in surface water and soil by pump heat engine group Transport to indoor end system.
Further, the source pump includes refrigerant, evaporator, compressor, condenser.
Further, the indoor end system includes heating terminal and refrigeration end.
Further, the anti-icing fluid storage tank is connected with ethylene glycol storage tank, by ethylene glycol storage tank supplement addition anti-icing fluid.
Further, the pipe of moisturizing is connected on the anti-icing fluid storage tank and buffer tank respectively.
The water of the above-mentioned utilization heat of transformation, earth-source hot-pump system heat technique, comprise the following steps:
Heat exchanger group is arranged in anti-icing fluid in surface water body bottom and soil contact position, anti-icing fluid storage tank by the 3rd circulating pump Group is pumped into heat exchanger group, and anti-icing fluid is absorbed after ambient water, ice and the soil moisture, into source pump;It is cold inside source pump Matchmaker absorbs temperature after the heat of anti-icing fluid and raised, and then the carburation by evaporation inside evaporator passes through the compressor of source pump Compression, the temperature of refrigerant is further improved, then refrigerant is converted into liquefaction from vapor state by condenser, and is discharged Amount of heat;After the cold water that this partial heat is pumped out by second circulation water pump group absorbs, in feeding buffer tank;Buffer tank Interior hot water is sent to heating terminal by first circulation water pump group, completes an inverse Carnot cycle, and the circulating repetition is carried out, water body institute User is constantly sent to containing physical thermal to use.
Water, the refrigeration process of earth-source hot-pump system of the above-mentioned utilization heat of transformation, comprise the following steps:
Gaseous refrigerant compression into high temperature and high pressure gas, is delivered in condenser by the compressor of source pump, passes through condensation Device outwards distributes heat, and the liquid refrigerant as cryogenic high pressure, the heat that the process refrigerant is distributed passes through the 3rd circulation After the water that water pump group is pumped out absorbs, heat exchanger group is sent into, is distributed heat in water body;Meanwhile, liquid refrigerant passes through pipeline The capillary of source pump is entered, by the throttling of capillary, then the A/C evaporator of refrigeration end is transported to;Air-conditioning steams Send out device space larger, liquid refrigerant absorbs heat rapidly after evaporator is entered by narrow capillary, indoor temperature reduction;System When cryogen is changed into the gas of isothermal and isobaric again, it is again introduced into compressor, completes a Carnot cycle, the circulating repetition is entered OK, constantly it is transported in the heat of user in water body.
Compared with prior art, the invention has the advantages that:
(1)The present invention not only make use of the physical thermal contained by the temperature change of water, while can also or ice-out solid using water-setting The latent heat of phase change discharged, the heat of same temperature extraction exceedes more than 15 times of prior art, that is, lifts same Heat, required water body only needs the 1/15 of existing process in theory, it is often more important that break the system of water source heat pump system freezing point About, northern various water be can be widely used for(Ice)Body, makes water resource heat pump obtain broader applications, in extremely cold area application, the system Advantage significantly, very little is influenceed by air themperature compared with air source heat pump, and Energy Efficiency Ratio can typically be up to more than 3.0;
(2)When heating, after heat exchanger group surrounding body is frozen into ice, because the thermal conductivity factor of ice is the thermal conductivity factor of water More than 4 times, so water source freeze not only be significantly increased refrigerant extract heat, while being also beneficial to heat exchanger tube periphery ice body and water body And the heat exchange of pipeline lower section soil containing saturation water so that the sensible heat and the heat of transformation of water can obtain profit in surface water and soil With while subaqueous soil sensible heat and ice temperature drop sensible heat are also used, so that available heat further increases;
(3)The heat of surrounding body and soil is absorbed by heat exchanger group(Including the heat of transformation)With discharge heat so that water, Di Yuan Heat pump takes the water body capacity of heat and the requirement of water quality to substantially reduce to it, and great rush will be played to promoting water, earth source heat pump Enter effect.
