Specific embodiment is as shown in the table:
To sum up, the present invention refers to heat source tower heat pump techniques, and makes improvements.Heat source tower heat pump is a kind of novel heat
Pump installation, it is exchanged heat by heat source tower and outdoor air, the heat in air is absorbed, by the tow taste heat of absorption with heat pump
Form is converted to high-grade heat to achieve the purpose that indoor heating and provide domestic hot-water.Heat source tower heat pump system
Although heat source also comes from air, it is different from the mode that conventional air source heat pump obtains energy from air, in winter, heat source
Tower heat pump unit is lower than 0 DEG C of mounting medium using freezing point, and -9 DEG C of high efficiency extraction or more, under the higher low temperature environment of relative humidity
The low-grade heat of air kind can be carried out heat supply, solves the problems, such as conventional air source heat pump temperature, eliminates conventional air
The electricity auxiliary heating of source heat pump.
Although above in conjunction with attached drawing, invention has been described, and the invention is not limited to above-mentioned specific implementations
Mode, the above mentioned embodiment is only schematical, rather than restrictive, and those skilled in the art are at this
Under the enlightenment of invention, without deviating from the spirit of the invention, many variations can also be made, these belong to of the invention
Within protection.
