Description of drawings
Below, only with way of example with reference to description of drawings preferred embodiment of the present invention, in the accompanying drawings:
Fig. 1 is used for heat pump schematic overview to water heating according to the present invention; And
Fig. 2 is the schematic overview of another embodiment of the present invention.
The specific embodiment
Referring to Fig. 1, be used for the heat pump of water heating is comprised evaporimeter 1 and condenser 5, this evaporimeter is by making the refrigerant evaporation send compressor 4 to from the heat of thermal source 3 on every side, this compressor links to each other with evaporimeter 1 fluid and is used for the compression refrigerant steam, and this condenser links to each other with compressor 4 fluids and is used for the heat of the compression refrigerant of controlling oneself is transmitted feedwater 6.Thermal source 3 is the surrounding air under the cold environment, and compressor 4 is to have liquid ejection outlet 7 and the conventional compressor that is used for cryogenic refrigeration.
Its form is that flexible adjuster 8 capillaceous links to each other with condenser 5 and compressor 4 fluids, so that sub-fraction condensing refrigerant shifted and reduce its temperature.Fluid ejection apparatus 9 has fluidly reduced the refrigerant part to temperature and has been ejected into the compressor 4 from capillary 8.Temperature has reduced the refrigerant part mixes with the refrigerant vapor that is compressed to intermediate pressure in compressor 4, and causes accurate at least two stages of compression.The refrigerant that combines (refrigerant vapor and refrigerant part) is compressed again subsequently, and is discharged in the condenser 5.
Capillary 8 is spirally coiled in around the pipeline 11, when passing pipeline 11 with convenient cryogen flow to main expansion valve 10 it is cooled off.Duct section 15 also is fixed on the part 21 of pipeline 11 via metal holder, and is arranged essentially parallel to pipe section 21 and contacts with it, so that promote the heat transmission between duct section 15 and the pipe section 21.Between duct section 15 and pipe section 21, also applied heat transfer cream.Duct section 15 can be deformed, so that consistent with pipe section 21 and improve and conduct heat.
Other parts of heat pump comprise liquid electromagnetic valve 23 and the filter/dryer 25 between condenser 5 and capillary 8, and this valve is used to make condensing refrigerant is mobilely carried out and disconnect.Be provided with peephole (sight glass) 27 on pipeline 11, it is used to observe the refrigerant that enters before the main expansion valve 10.On auxiliary piping 31, also be provided with deicing magnetic valve 29.
The following describes the operational circumstances of heat pump.The heat that refrigerant in the evaporimeter 1 is taken from surrounding air 3 is evaporated.Compressor 4 extracts the refrigerant vapor of flash-pot 1, and with it from low pressure, low-temperature steam state boil down to high pressure, high-temperature vapour state.Then, high pressure, hyperthermia induced refrigerant vapor are discharged to condenser 5, and this condenser plays the work of heat exchanger in order to heat is become water 6 from refrigerant vapor.The result of this process is that refrigerant is condensed into liquid and cold excessively.
Then, liquid cryogen passes liquid electromagnetic valve 23 and filter/dryer 25, so that remove moisture and dirt in the refrigerant.After most of liquid cryogen passes filter/dryer 25, go to main expansion valve 10 with regard to flowing through pipeline 11.Liquid cryogen expands and passes main expansion valve 10, causes its pressure and temperature to descend.The temperature of refrigerant just is lower than the temperature of surrounding air 3 this moment.Then, refrigerant enters evaporimeter 1, there, is transmitted to refrigerant once again from the heat of surrounding air 3.The refrigerant that has evaporated finally is discharged in the compressor 4, and this kind circulation is carried out repeatedly.
When most of liquid cryogens enter main expansion valve 10, there is sub-fraction liquid cryogen (its can account for whole refrigerant about 10%) to enter the bypass channel 12, and passes liquid injection magnetic valve 13 and go to capillary 8 from pipeline 11.Capillary 8 makes the refrigerant demi-inflation, causes its pressure and temperature to descend.Partly pass duct section 15 and check-valves 17 and go to jet 7 so temperature has reduced refrigerant.So injected compressor 4 of giving of the refrigerant of liquid state/steam form part, so that mix and its cooling (be that is to say with the superheated refrigerant vapor after handling through pseudo-first-order compression in the compressor 4, after refrigerant vapor had been compressed into intermediate pressure, the refrigerant part is injected to be advanced in the compressor).Consequently, accurate two stages of compression has taken place, and combined refrigerant vapor and refrigerant partly are compressed to final pressure.The refrigerant that has compressed is discharged in the condenser 5 with that.
Because the refrigerant in the compressor 4 has passed through pseudo-first-order compression at least, temperature has been reduced refrigerant partly to be introduced in the compressor 4 and mixes with superheated refrigerant, will reduce the temperature of next rank compression refrigerant before, and therefore reduce the temperature in the compressor so that carry out subsequent compression.Be lowered to regard to the pressure ratio that causes the compression of each rank like this and conform with the desired degree of accurate two stages of compression, and therefore improve the efficient of each compression.The cause of spraying owing to the refrigerant segment fluid flow makes accurate two stages of compression combine in compressor with middle the cooling, also can reduce the power (power) that from heat pump, extracts (with single stage compress comparatively speaking).Fluid injection valve 13 and check-valves 17 are being controlled injected timing and the direction that temperature in the compressor 4 has reduced the refrigerant part of advancing.Therefore, just can controllably reach accurate at least two stages of compression with single-stage compressor.The result is that the temperature difference between condensation temperature and the evaporating temperature has obviously increased, so just increased the environment temperature opereating specification of heat pump.
The recommendation form of flexible adjuster 8 is a capillary, so that heat pump is simplified.The temperature that also can allow capillary 8 has reduced the refrigerant part and has only absorbed in its expansion from being used after the heat in the pipeline 11 and before entering main expansion valve 10.As mentioned above, capillary 8 is spirally coiled in around pipeline 11 and the duct section 15, and this duct section is arranged essentially parallel to pipeline 11 and contact with it.In this way, the refrigerant in the pipeline 11 will additionally be cooled off, and has so just reduced the risk that splash (flashing) took place before entering main expansion valve 10 liquid cryogen.
In the present embodiment, although there is the whole refrigerant of about 10% quantity to be transferred to capillary 8, the quantity of this transfer according to around the temperature of thermal source and desired water temperature and decide.
Although preferred embodiment of the present invention above has been described, understand that each building block of this system can change in other embodiments.
Fig. 2 has shown second embodiment, and wherein, corresponding component is all represented with same Reference numeral.In a second embodiment, flexible adjuster 8 is for having the expansion valve 33 of intercooler 35.Intercooler 35 links to each other with condenser 5 and expansion valve 10 fluids.Bypass channel 12 is positioned at intercooler 35 downstreams.Liquid cryogen from condenser 5 enters intercooler 35.Via bypass channel 12 before being extracted liquid injection valve 13, intercooler 35 makes the liquid cryogen cooling earlier in refrigerant part.Refrigerant partly passes expansion valve 33 so that further reduce its temperature and pressure.Temperature has reduced refrigerant and has partly then turned back to cooler 35, so as be delivered to the liquid cryogen exchanged heat of passing intercooler 35 before the compressor 4 from condenser 5.As in first embodiment, refrigerant part is mixed with refrigerant vapor in compressor and is caused accurate at least two stages of compression.Liquid cryogen part is extraction from middle cooler 35 after, thereby will reduce the possibility of refrigerant in expansion valve 33 and main expansion valve 9 splash in the two.
In some other embodiment,, just can cause multi-stage compression if requirement has reduced the refrigerant part by other those temperature after spraying the compression processing of the accurate second level.
Compressor can be the refrigeration compressor that wherein has one or more liquid ejection outlet, or is modified as any compressor that is equipped with liquid ejection outlet.
Heat pump has been described simplifiedly, so that help to understand the present invention.Recognize in this heat pump, to also have other parts and control and the used mechanical device of safety not to give explanation, but do not influence the basic operation of this system recommendation form like this.
Recommendation form of the present invention discussed above provides water has been heated used energy efficient and practical system, especially sends hot air supply heat pump system under the chilling temperatures environment.Recommendation form of the present invention substitutes current fossil-fuel-fired boiler, thereby reduces any adverse effect to environment.
Although with reference to special example the present invention has been described, the professional can understand, can implement the present invention with many other forms.
