Description
Technical Field
The invention belongs to the technical field of heat pump systems, and particularly relates to an air source heat pump energy station.
Background
The air source heat pump unit is also called as an air-cooled heat pump unit and is a general name of an air-air heat pump and an air-water heat pump. The method is characterized by comprising the following steps: the machine has two purposes, and has double functions of cooling in summer and heating in winter; the environmental energy is taken from air in natural environment, and the energy source limiting factor is less; the installation is convenient, and the building top layer or the outdoor open field is placed in the open air; the investment for one time is low, so the method is widely applied.
However, current air source heat pump systemsWhen the heat exchanger is used for heating, the ambient air heat exchanger adopts air-refrigerant liquid-vapor phase change to directly exchange heat, the unit volume of the refrigerant liquid-vapor phase change absorbs large heat, taking R22 as an example, the enthalpy of the liquid-vapor phase change is 2.78 multiplied by 10
5KJ/m
3And the specific heat of the air is only 0.78KJ/m
3K, if the temperature difference of the air heat exchange reaches 10K, 3.5X 10
4m
3Heat exchange capacity of air and 1m
3The refrigerant absorbs equivalent heat through liquid-vapor phase change, and the medium flow difference of a heat exchange interface reaches 4 orders of magnitude. Meanwhile, the liquid-vapor phase change of the refrigerant only occurs at a liquid-vapor phase change interface, namely, a liquid-vapor phase change area of the refrigerant can only be distributed at a very small part of the heat exchanger, and even if the volume of the air-refrigerant liquid-vapor phase change heat exchanger is increased, the effective heat exchange area capable of generating the liquid-vapor phase change of the refrigerant is difficult to increase along with the increase of the liquid-vapor phase change area of the refrigerant, so that the heat exchanger adopting the direct heat exchange of the air medium and the refrigerant phase change theoretically has a bottleneck, and the heat.
Therefore, the traditional air source heat pump is limited by the heat exchange capacity of an air-refrigerant liquid-vapor phase heat exchanger, the heat exchange power of the heat pump is relatively low, and the general power of a large single heat exchanger and the heat pump is about 6 horsepower. Because the increase of the direct heat exchange quantity of the air medium and the refrigerant phase change cannot effectively increase the effective area of the heat exchanger by increasing the apparent area of the heat exchanger, and the actual significance of the increase of the area of the air-refrigerant liquid-vapor phase heat exchanger by series-parallel connection is not large, the traditional air-refrigerant liquid-vapor phase heat exchanger and the compressor are in one-to-one configuration, namely the air-refrigerant liquid-vapor phase heat exchanger (evaporator) and the compressor are in one-to-one configuration during heating, and the air-refrigerant liquid-vapor phase heat exchanger (condenser) and the compressor are in one-to-one configuration during cooling.
Therefore, the traditional air source heat pump adopts a one-to-one configuration method of an air-refrigerant liquid-vapor phase converter and a compressor, and the power of the formed unit is only about 6 horsepower at most; the single unit combines the large-volume air-refrigerant liquid-vapor phase converter, the small-volume high-power compressor, the water-refrigerant vapor-liquid phase change heat exchanger and the expansion valve into a module, and is additionally provided with a protective shell. The large-scale of the traditional air source heat pump is realized by simply connecting a large number of monomer units in parallel, the large-scale is realized by simply overlapping small modules, the air-refrigerant liquid-vapor phase converter and the compressor are configured in a one-to-one way, the stop/start of the compressor corresponds to the stop/start of the air-refrigerant liquid-vapor phase converter, and the excess heat exchange capacity of the large-volume air-refrigerant liquid-vapor phase converter is not fully utilized when the compressor is in an unsaturated operation state, so that the large-scale does not bring corresponding scale effect. The air-refrigerant liquid-vapor phase converter with large volume and the compressor with small volume and high power are combined into a module, and a protective shell is additionally arranged, so that the cavity resonance is easily caused; meanwhile, the protection shell forming the large-scale unit also limits the arrangement and placement positions and space selection of the unit, and the cold and hot island effect is easy to generate.

The natural energy extraction side module and the heat pump unit module shown in this embodiment and fig. 1 are described by taking a one-to-one matching as an example.
Because the ambient air-antifreeze heat exchanger 1 can be independently arranged, only the fan 11 for increasing the wind speed is arranged, the ambient air-antifreeze heat exchanger belongs to a low-vibration and low-noise module, the influence on the environment and the building is small, and the ambient air-antifreeze heat exchanger 1 can absorb the heat of the ambient air at the most efficient position according to the environmental conditions such as spaciousness, the surrounding environment state and wind field distribution, effectively and rapidly discharges the air after heat exchange, and avoids the cold island effect.
The environment air-antifreeze fluid heat exchanger 1 is large-sized and modularized independently, the heat exchange area is greatly improved, the fan 11 is configured to be different from a traditional air source heat pump, the fan 11 adopts a head-on blowing heat exchange mode instead of a shell air draft mode, the head-on blowing mode can further increase the air quantity by fully utilizing a jet flow principle, the air quantity is greatly increased, and meanwhile, the wind speed of the head-on blowing mode is perpendicular to the heat exchange surface, so that the maximum effective air quantity is ensured to pass through.
The heat exchange medium of the ambient air-antifreeze heat exchanger 1 is antifreeze, the freezing point of the antifreeze is lower than the ambient air temperature, the ambient air-antifreeze heat exchanger 1 is a single heat exchanger, or a plurality of heat exchangers connected in parallel, or a plurality of heat exchangers connected in series, and the single heat exchanger is illustrated in this embodiment and fig. 1 as an example.
The heat pump unit module comprises an antifreeze solution-refrigerant liquid-vapor phase converter 4, an antifreeze solution heat exchange circulating system, a compressor unit 5, an expansion valve 6, a water-refrigerant vapor-liquid phase change heat exchanger 7 and a water heat exchange circulating system, the user energy supply side module comprises a buffer hot water tank 10 and a user heat supply water pump 9, and the user energy supply side module is connected with a user system. An antifreeze heat exchange circulating pump 3 is arranged on the antifreeze heat exchange circulating system, a water circulating pump 8 is arranged on the water heat exchange circulating system, the antifreeze-refrigerant liquid-vapor phase change heat exchanger 4 is connected with the antifreeze expansion water tank 2 through the antifreeze heat exchange circulating system, and the water-refrigerant vapor-liquid phase change heat exchanger 7 is connected with the buffer hot water tank 10 through the water heat exchange circulating system.
The compressor unit 5 of the present invention is a plurality of compressors. The antifreeze liquid-refrigerant liquid-vapor phase converter 4 and the compressor are connected in a one-to-many manner, and the water-refrigerant vapor-liquid phase change heat exchanger 7 and the compressor are connected in a one-to-many manner.
In the embodiment, an antifreeze medium is added in the air-refrigerant liquid-vapor phase conversion heat of the traditional air source heat pump system, and primary heat exchange is changed into secondary heat exchange, namely, ambient air-antifreeze heat exchange and antifreeze-refrigerant liquid-vapor phase change heat exchange.
The scheme design principle of the embodiment illustrates that:
after the anti-freezing solution-refrigerant liquid-vapor phase conversion heat replaces the traditional air-refrigerant liquid-vapor phase conversion heat, the difference of the heat enthalpies of the heat exchange media at two sides of the anti-freezing solution-refrigerant liquid-vapor phase conversion heat is greatly reduced, even if the temperature difference of the anti-freezing solution before and after heat exchange is only 2K and is about 300m
3Heat exchange capacity of antifreeze and 1m
3The heat absorbed by the refrigerant through liquid-vapor phase change is equivalent, the medium flow difference of the heat exchange interface is reduced to be within 2 orders of magnitude, and the difference is reduced100 times. Therefore, the antifreeze liquid-refrigerant liquid-vapor phase converter 4 has no bottleneck in the heat exchange capacity, can be miniaturized, can be arbitrarily enlarged relative to the compressor, and is symmetrically configured with the water-refrigerant vapor-liquid phase change heat exchanger 7, the antifreeze liquid-refrigerant liquid-vapor phase converter 4 can be matched with a large compressor or a compressor unit, and can also be configured with a plurality of compressors in parallel, and the heat exchanger performance can be fully exerted.
Meanwhile, the heat exchange cold medium of the ambient air-antifreeze heat exchanger 1 is low-temperature antifreeze, and phase change does not exist through temperature difference heat exchange of the antifreeze. The pipeline of the ambient air-antifreeze heat exchanger 1 is filled with antifreeze, so that heat exchange is uniform and stable, the heat exchange capability is not bottleneck, and the inherent defect of low specific heat of air can be effectively overcome through arbitrary upsizing. The ambient air-antifreeze solution heat exchanger 1 can be freely matched with a heat pump unit module, and can realize one-to-one or one-to-many or many-to-one in a series or parallel mode. No matter how the compressor works, the arbitrarily large-sized ambient air-antifreeze heat exchanger 1 can be put into operation comprehensively, so that the heat exchange capacity is fully exerted, and a large-scale effect is obtained.
The heat pump unit module adjusts the heating (cooling) capacity internally by the number of compressor on/off. When the system is in an unsaturated running state, the heating (refrigerating) quantity is reduced, the heat exchange capacity of the ambient air-antifreeze heat exchanger 1 generates an excess value, and the effect of reducing the temperature difference between ambient air and a cold medium is generated, namely the temperature difference between antifreeze and ambient air is reduced. This effect is transmitted to the compressor through the antifreeze, and the difference between the condensing temperature and the evaporating temperature of the refrigerant is reduced, so that the working efficiency of the compressor is improved. In this embodiment, when the anti-freezing liquid-refrigerant liquid-vapor phase change heat exchanger 4 and the water-refrigerant vapor-liquid phase change heat exchanger 7 are symmetrically arranged in a one-to-many manner with the compressors, and the heat supply capacity of the heat pump unit is adjusted along with the change of the ambient temperature by stopping/starting the compressors in the heat pump unit module, the scale effect of the heat exchangers is also reflected: the heat exchange capacity, namely the heat exchange area, of the antifreeze liquid-refrigerant liquid-vapor phase change heat exchanger 4 and the water-refrigerant vapor-liquid phase change heat exchanger 7 is configured according to the whole opening of a compressor in the heat pump module, when the compressor is partially in a closed state, the scale heat exchange capacity of the heat exchanger is reflected, if the flow of a heat exchange medium is not changed, the temperature difference of media at two sides of the heat exchanger is reduced, and the working efficiency of the compressor is improved; if the temperature difference of the media on the two sides of the heat exchanger is not changed, the flow of the heat exchange media can be reduced, namely the circulation flow of the antifreeze heat exchange circulating pump 3 and the circulation flow of the water circulating pump 8 can be reduced, so that the energy consumption of the system is effectively reduced; meanwhile, the fan power of the ambient air-antifreeze heat exchanger 1 can be reduced until the fan 11 stops running. In a word, after the large-scale operation is carried out, the scale effect is reflected, and the energy efficiency ratio of the system is improved.
The heat pump unit module is independently installed in a closed manner, and high-power equipment of the system is integrated in a small-volume module, so that various enhanced vibration and noise reduction measures are easy to adopt, and the method is easy to realize economically and technically; meanwhile, the heat pump unit and the ambient air-antifreeze heat exchanger 1 are arranged in a split manner, so that the cavity resonance phenomenon caused by the integration of the ambient air-antifreeze heat exchanger 1 and the compressor is avoided; the independently arranged ambient air-antifreeze heat exchanger 1 can absorb the heat of the ambient air at the most efficient position according to the environmental conditions such as spaciousness, ambient environmental state and wind field distribution, and effectively and rapidly discharges the air after heat exchange, thereby avoiding the cold and hot island effect; compared with the traditional air source heat pump air heat exchanger and compressor, the volume of the compressor module which is independently arranged is greatly reduced, the energy exchange with the ambient air is not needed to be considered, a closed means can be adopted, the influence of environmental dust, water vapor and the like is thoroughly eliminated, and various vibration reduction and noise reduction measures are easy to take.
