Abstract
An air source heat pump evaporator comprises a heat exchanger, and a plurality of groups of cold medium bypass branches arranged in the heat exchanger, wherein each group of the cold medium bypass branches are coiled from bottom to top in such a manner that the cold medium bypass branches are close to the windward side and the leeward side of the heat exchanger at intervals. The air source heat pump evaporator has the advantages that: (1) each cold medium bypass branch extends upwards in such a manner as to be close to the windward side and the leeward side of the heat exchanger at intervals when in use, thereby facilitating full heat exchange of the cold medium air; and (2) the evaporator has excessive heat due to the fact that the evaporation area of the lower part of the heat exchanger is larger than that of the upper part of the heat exchanger, so that the lower part of the evaporator has higher temperature to prevent the generation of frost even if a lot of condensed water is generated on the surface of the lower part of the evaporator in the cold weather, thereby improving the heat exchange efficiency.
Description
(1) technical field
The utility model relates to a kind of air source heat pump evaporation device.
(2) background technology
Energy-saving and emission-reduction are current hot issues, and air energy heat pump is because of it is efficient, environmental protection has obtained fast development in recent years, and for improving the air energy heat pump performance, way is to strengthen heat exchanger area usually.Common dual-row evaporator can not fine solution evaporimeter internal refrigeration storage agent and air side reverse heat-exchange, and efficiency is not ideal enough.
When moving in the winter time in addition, the easy frosting of fin, because condensed water falls from top to bottom, it is more that water is assembled in the bottom, therefore easier formation frost layer, the frost layer influences heat exchange efficiency progressively to vertical spread.
(3) summary of the invention
In order to overcome the existing dissatisfactory deficiency of air energy heat pump efficiency, the utility model provides a kind of air source heat pump evaporation device, makes the air source heat pump heat exchange efficiency higher.
Further, the utility model provides a kind of air source heat pump evaporation device that is difficult for frosting.
The technical scheme in the invention for solving the technical problem is: a kind of air source heat pump evaporation device, comprise heat exchanger, be provided with array coolant distribution arm in the described heat exchanger, every group of described coolant distribution arm coils from bottom to top, when upwards coiling, refrigerant branch interval ground is near the windward side and the lee face of described heat exchanger.
Further, the disengagement area of heat exchanger bottom is greater than the disengagement area on heat exchanger top.
Further, described coolant distribution arm has five groups, below the disengagement area of two groups of coolant distribution arm place heat exchangers greater than the disengagement area of top three groups of coolant distribution arm place heat exchangers.
The beneficial effects of the utility model are: 1. in use, each coolant distribution branch interval ground extends upward near the windward side and the lee face of described heat exchanger, helps the abundant heat exchange of refrigerant air.Since the disengagement area of heat exchanger bottom greater than the disengagement area on heat exchanger top, evaporimeter has overheated, makes that by this measure the evaporimeter temperature of lower is higher, under the cold weather situation, though bottom evaporator surface condensed water is more, also is difficult for frosting, has improved heat exchange efficiency.
(4) description of drawings
Fig. 1 is a side view of the present utility model.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, a kind of air source heat pump evaporation device comprises heat exchanger 1, be provided with five groups of coolant distribution arms 2 in the described heat exchanger 1, every group of described coolant distribution arm 2 coils from bottom to top, and when upwards coiling, refrigerant branch interval ground is near the windward side 3 and the lee face 4 of described heat exchanger.Below the disengagement area of two groups of coolant distribution arm place heat exchangers greater than the disengagement area of top three groups of coolant distribution arm place heat exchangers.
Refrigerant is divided into five branch roads by minute fluid 5 and enters evaporimeter, flows out evaporimeter at last and gathers.In the refrigerant flow process, air is at the dirty pervaporation device of fan effect, because heat exchange action, air themperature descends, and carries out heat exchange at air and refrigerant.In use, each coolant distribution arm 2 compartment of terrain extends upward near the windward side 3 and the lee face 4 of described heat exchanger, helps the abundant heat exchange of refrigerant air.Because the disengagement area of heat exchanger bottom is greater than the disengagement area on heat exchanger top, evaporimeter has overheated, makes that by this measure the evaporimeter temperature of lower is higher, under the cold weather situation, though bottom evaporator surface condensed water is more, also is difficult for frosting, has improved heat exchange efficiency.
Claims (3)
