Description
Technical field
The present invention relates to a kind of composite solar air source heat pump, the regenerative resource such as solar energy and air heat energy can be made full use of,
According to solar radiation condition and outside air temperature, circulated by the heat pipe of solar energy, heat pump cycle, the heat pipe circulation of air-source,
Heat pump cycle and the reasonable switching of combined cycle system thereof, realize efficient heat supply and domestic hot-water supply.This technology is particularly well-suited to
Winter heat supply and annual domestic hot-water supply, it can also be used to the concurrent heating of soil source heat pump system, belong to heating field.
Background technology
Whole world building heat supplying and domestic hot-water's energy consumption are very big, and living standard and habits and customs that developed country is higher cause huge
Hot water demand and energy resource consumption, developing country then can keep hot water energy along with development and the growth in the living standard of urbanization
The rapid growth of consumption.Traditional heating system is based primarily upon the mode of combustion of fossil fuel, and not only efficiency is low but also seriously polluted；
Hot water supply system mainly uses gas heater and electric heater, the problem that there is energy grad waste.Heat supply and life
Hot water increasingly become energy-saving and emission-reduction, administer haze pay close attention to one of field.
In recent years, solar water heater and air source hot pump water heater have obtained bigger development.But, when solar radiation is not enough
Time, the heating effect of solar water heater or heating system will be had a greatly reduced quality, it usually needs a set of standby system ensures overcast and rainy
Reliability of heat-supply system time gas and solar radiation are poor, reduces its energy-saving effect.Additionally, at the beginning of solar thermal collector is higher
Investment and bigger erection space require the obstacle being also to restrict its further large scale application.For air source heat pump hot water
Device or heating system, owing to its heating efficiency and heating capacity all constantly can be decayed with the reduction of outside air temperature, the most just reduce it
Reliability is heated under low temperature.Current air source heat pump is only with the heat energy in air, it is impossible to effectively utilize solar radiant energy,
Although and actually many times temperature in winter is the lowest, but intensity of solar radiation still be enough to produce required hot water.
In view of solar water heater cannot make full use of Low emissivity solar energy, air source heat pump cannot utilize the problem of solar radiant energy,
The technical scheme that solar energy and heat pump techniques combine has been obtained increasing favor.Current this kind of technical scheme is broadly divided into
Three classes: when (1) solar radiation is strong not, the low-temperature water heating that solar thermal collector is produced as the evaporation side thermal source of water resource heat pump,
Improve efficiency and the efficiency of heat pump of heat collector, be then switched to solar energy when that solar radiation being strong and directly heat (such as patent
CN201220382850.9).Such scheme simply improves the efficiency of solar thermal collector, does not solve without heating during solar energy
Problem；(2) use the solar thermal collector of direct-expansion type, during i.e. cold-producing medium is passed directly into solar thermal collector, so can realize
Solar energy directly heats and solar heat pump heating pattern, can reduce certain power consumption of compressor (such as patent
CN201110388936.2), but still not solve without heating problem during solar energy；(3) a direct-expansion type solar energy collection is used
Hot device and a wind-cooled evaporator, the when that solar radiation being enough, solar energy directly heats, and does not has the sun or radiates more weak bar
Run air source heat pump pattern (such as patent CN201120054202.6) under part, but such scheme can not utilize under Low emissivity
Solar energy, can not realize directly heating and solar energy and heating combining of air heat energy, to solar energy and sky of air heat energy
The Quality degree of effective utilization of gas heat energy is the highest.
It should be noted that when the hot water temperature needed under certain situation is relatively low or outer temperature is the highest (during outer temperature 30 DEG C in such as summer,
Produce the low-temperature water heating of 10～20 DEG C, storing across season for air heat energy), extraneous air heat energy also is able to directly heat,
And all realized by air source heat pump at present, cause the energy consumption heated higher.
Sum it up, current solar heat pump and air source heat pump technical scheme are more fully utilizing not with higher efficiency
Bigger room for improvement is there is also with the solar energy of radiation intensity and the air heat energy aspect of different temperatures grade.If in conjunction with the sun
More reasonably technical scheme and operation side can be gone out with the thermal load demands feature construction of the respective characteristic of air heat energy and user
Method, then can be greatly improved solar energy and the utilization ratio of air heat energy and producing level.
