Abstract
The utility model discloses an automatic overlaying type heat pump system with a fine stiller, which includes a condenser (1), a second drying filter (10), an evaporator (13) and a compressor (14) sequentially connected in series by a circulation loop; an output end of the condenser (1) is communicated to the second drying filter (10) after passing through the fine stiller (3), a counter flow heat exchanger (4), a first drying filter (6) and an evaporative condenser (8) sequentially; moreover, another output end of the fine stiller (3) is communicated to the evaporative condenser (8) through a high temperature level expansion valve (15), and is reversely communicated to an input end of the compressor (14) through the counter flow heat exchanger (4). The automatic overlaying type heat pump system with the fine stiller is combined with a heat pump, the pressure ratio of the compressor is reduced, the work temperature difference of the heat pump is enlarged, and the use range of the heat pump system is widened.
Description
Technical field
The present invention relates to a kind of heat pump, more particularly, relate to the improvement of heat pump circulating system.
Background technology
Under the prior art, one-stage steam compressed formula heat pump is subjected to the restriction of pressure ratio and condensation temperature, is difficult to the demand of reaching a high temperature.Adopt automatic cascade formula heat pump can allow heat pump be widely used in the high temperature field.
Summary of the invention
The present invention establishes the automatic cascade formula heat pump of rectifier, and the pressure ratio that has been intended to reduce compressor has increased the work temperature difference of heat pump, has enlarged the scope of application of heat pump.
In order to achieve the above object, the invention provides a kind of automatic cascade formula heat pump of establishing rectifier, comprise condenser, second device for drying and filtering, evaporimeter, compressor that closed circuit is contacted successively.The output of described condenser is communicated to described second device for drying and filtering through rectifier, contra-flow heat exchanger, first device for drying and filtering and evaporative condenser successively; In addition, another output of described rectifier is communicated to described evaporative condenser by a high temperature level expansion valve, and the reverse input that passes to described compressor by described contra-flow heat exchanger.Wherein, the input of described evaporimeter is provided with a low temperature level expansion valve, and the two ends of described second device for drying and filtering are provided with the 4th ball valve and the 3rd ball valve respectively, and the two ends that are positioned at described first device for drying and filtering are provided with first ball valve and second ball valve respectively; The output of described condenser also is provided with a magnetic valve.
The automatic cascade system that the present invention has rectifier combines with heat pump, has reduced the pressure ratio of compressor, has increased the work temperature difference of heat pump, has enlarged the scope of application of heat pump.
Description of drawings
Fig. 1 is the operation principle schematic diagram that the present invention establishes rectifier automatic cascade heat pump.
The specific embodiment
A kind of as shown in Figure 1 automatic cascade formula heat pump of establishing rectifier comprises condenser 1, second device for drying and filtering 10, evaporimeter 13, compressor 14 that closed circuit is contacted successively.The output of described condenser 1 is communicated to described second device for drying and filtering 10 through rectifier 3, contra-flow heat exchanger 4, first device for drying and filtering 6 and evaporative condenser 8 successively; In addition, another output of described rectifier 3 is communicated to described evaporative condenser 8 by a high temperature level expansion valve 15, and the reverse input that passes to described compressor 14 by described contra-flow heat exchanger 4.Wherein, the input of described evaporimeter 13 is provided with a low temperature level expansion valve 12, the two ends of described second device for drying and filtering 10 are provided with the 4th ball valve 11 and the 3rd ball valve 9 respectively, and the two ends that are positioned at described first device for drying and filtering 6 are provided with first ball valve 5 and second ball valve 7 respectively; The output of described condenser 1 also is provided with a magnetic valve 2.Among the figure, a, b, c, d represent cooling water outlet, cooling water inlet, delivery port and water inlet respectively.
The automatic cascade heat pump of band rectifier of the present invention uses a compressor, adopts the binary non-azeotropic mixed working medium to make cold-producing medium, and through behind the segregator, the higher boiling refrigerant component is condensed into liquid, and low boiling component still is a gas.Through after the rectification and purification of rectifier, higher boiling cold-producing medium and low boiling point refrigerant component are separated, and wherein the higher boiling refrigerant liquid enters the evaporative condenser evaporation by expansion valve, thereby condensation enters the low boiling component of evaporative condenser.After being condensed into the low boiling point refrigerant process low temperature level expansion valve of liquid, enter evaporator evaporation, obtain more cold.The higher boiling refrigerant gas that goes out evaporative condenser enters the gas that contra-flow heat exchanger and rectifier come out and cools off purification, returns compressor afterwards.Two kinds of cold-producing mediums in the system are worked under identical condensing pressure and evaporating pressure.
The above; only be the preferable specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
