Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provide a kind of can make heat pump air conditioner unit have higher annual energy resource consumption efficiency value improve simultaneously heat pump air conditioner heating capacity, improve heat pump air conditioner and heat defrosting efficiency, improve the air source heat pump air-conditioner finned heat exchanger syndeton of the overall price/performance ratio of heat pump air conditioner unit.
According to the technical scheme that the utility model provides, described air source heat pump air-conditioner finned heat exchanger syndeton, comprise finned tube, discharge and separating tube, it comprises is the finned tube of even rows stacked spaced apart in the height direction, and often row has the finned tube that some length directions are introversion and extroversion setting, two finned tubes adjacent in each row are in the height direction in shifting to install, two finned tubes adjacent in each row are connected, two finned tubes being positioned at the rightmost side in every two rows are connected, the discharge described in finned tube parallel connection access of the row leftmost side is positioned in every two rows, the separating tube described in finned tube parallel connection access of the lower row leftmost side is positioned in every two rows.
Often row has the finned tube of identical radical.
Often row has 4 finned tubes.
The advantage of the utility model patent is:
1, when unit cost is constant, the annual energy resource consumption efficiency value of unit can be significantly improved, improve heating capacity and the heating energy efficiency ratio of unit simultaneously;
2, when keeping the annual energy resource consumption efficiency value of unit constant, can effectively reduce costs;
3, when unit cost is constant, the reliability that unit heats defrosting efficiency, low-temperature heating performance and unit can be improved.
Adopt the utility model finned heat exchanger, unit cooling operation is with when heating running, part countercurrent flow can be realized between cold-producing medium and air, while maintaining unit refrigeration efficiency ratio as far as possible, significantly improve the heating energy efficiency ratio of unit, thus significantly improve the annual energy resource consumption efficiency of unit.
