Abstract

The utility model provides an indoor air conditioner evaporator and an indoor air conditioner, which can solve the problem that the energy efficiency requirements of the air conditioner can not be met due to the small heat exchange area in the prior art. The utility model has the technical scheme that: the indoor air conditioner evaporator comprises three rows of U-shaped pipes and fins, and the evaporator adopts a five-way inlet and five-way outlet flow; the flow of each way is as follows: a refrigerant flows through the first row of U-shaped pipes from bottom to top, flows through the second row of U-shaped pipes from top to bottom, flows through the third row of U-shaped pipes from bottom to top and flows out of the evaporator. By improving the arrangement of the U-shaped pipes of the evaporator, the heat exchange flow is changed, and the heat exchange area of the evaporator is increased; and under the condition that the windward area is considerable, the heat exchange quantity of the indoor air conditioner is improved so as to ultimately meet the requirements of new energy efficiency standards.

Description

A kind of air conditioner indoor unit evaporator and indoor apparatus of air conditioner
Technical field
The utility model belongs to air-conditioning and Refrigeration Engineering technical field, specifically, relates to a kind of floor air conditioner indoor machine evaporimeter and adopts the indoor apparatus of air conditioner of this evaporimeter.
Background technology
Present many 3P floor air conditioner indoor machine evaporimeters use the double internal thread U type copper pipe heat exchanger of specification φ 7.0mm or φ 9.52mm, be applied on 4,5 grades of efficiencies of constant speed, the low-cost product, generally each branch road is " U " type or " U " type of falling or " N " type of falling or combination layout.Along with the promotion and implementation of country about the new efficiency standard of family expenses constant speed air-conditioning, the high energy efficiency product will become main flow air-conditioning product, and this dual-row heat exchanger can not satisfy the efficiency requirement of 3P high energy efficiency floor air conditioner because heat exchange area is little.
The utility model content
The utility model provides a kind of air conditioner indoor unit evaporator and indoor apparatus of air conditioner, can solve that prior art exists and can not satisfy the problem that the air-conditioning efficiency requires because heat exchange area is little.
For solving the problems of the technologies described above, the utility model is achieved by the following technical solutions:
A kind of air conditioner indoor unit evaporator, comprise U pipe and fin, described evaporimeter adopts 5 the tunnel to advance 5 tunnel flow processs that go out, comprise three row U pipes, the flow process on each road is cold-producing medium and flowed through for first row U when pipe from the bottom to top,, flow out evaporimeter when flowing through the 3rd row U pipe from the bottom to top from top to bottom when flowing through the second row U pipe.
The three row U type copper pipe console mode indoor machine evaporations that the utility model provides, arrange by the U pipe that improves evaporimeter, the shunting of appropriate design evaporimeter, change its heat exchange process, strengthened the heat exchange area of evaporimeter, under the suitable situation of front face area, improve indoor set heat exchange amount, finally satisfy the requirement of new efficiency standard.
Further, described U pipe employing specification is the U type pipe of φ 7.0mm.
Further, the central span of described U pipe is 21mm.
Further, the wide employing of described fin sheet 13.65mm.
A kind of indoor apparatus of air conditioner adopts above-mentioned evaporimeter.
The utility model provides a kind of 3P separated floor air conditioner indoor machine high-efficiency evaporator, is made up of three row's evaporator parts, inlet tube assembly, outlet assembly and elbow or mid-span pipe.Evaporator part adopts the female type copper pipe of specification φ 7.0mm as U type pipe, the wide employing of fin sheet 13.65mm, and the central span of U type pipe is 21mm, adopts 5 the tunnel to advance 5 tunnel flow processs that go out.The import cold-producing medium of evaporimeter is the little two-phase fluid of mass dryness fraction, the cold-producing medium mass dryness fraction increases gradually in the evaporation process, the outlet mass dryness fraction is 100% overheated gas, consider the influence of gravity factor, each flow process along separate routes all should be kept flow direction from bottom to up as far as possible, to reduce the pressure loss in the evaporation process, improve the flow velocity of cold-producing medium, increase the heat convection amount.The separated floor air conditioner indoor machine wind field distributes very inhomogeneous, and base of evaporator is nearest from fan, and surface wind speed is higher, helps heat exchange, and the top wind speed is then on the low side, is unfavorable for heat exchange; But when refrigeration produces condensate water on the evaporimeter, flow from top to bottom, so evaporimeter more down condensate water is many more from the top, windage is big more, is unfavorable for heat exchange more.Factor to sum up, result according to the actual match debugging test, the U type pipe number of each minute flow process rationally is set, each road flow process heat exchange amount is consistent, and the flow process on each road is cold-producing medium and flowed through for first row U when pipe from the bottom to top, the second row U manages from top to bottom, and the 3rd row is flowed out evaporimeter, maximized performance exchange capability of heat more from the bottom to top.
Compared with prior art, advantage of the present utility model and good effect are:
Air conditioner indoor unit evaporator of the present utility model is applied to the 3P separated floor air conditioner indoor machine, has improved the heat exchange amount, has improved the Energy Efficiency Ratio of air-conditioning.
