Abstract
The present invention provides an indoor tube-crossed heat exchanger of floor air conditioner. It includes liquid inlet tube group, liquid outlet tube group, lower flow channel, intermediate flow channel and upper flow channel. It is characterized by that at least partial pipeline of lower flow channel is communicated with partial pipeline of upper flow channel. Said invention can raise heat exchange efficiency of heat exchanger, and EER so as to meet design requirements of high-effective floor air conditioner.
Description
Technical field
The present invention relates to the cabinet air-conditioner indoor heat converter, is the improvement to existing heat converter structure.
Background technology
At present, cabinet-type air conditioner air-conditioning indoor heat converter also claims evaporimeter, generally adopts multichannel shunting design.Be generally 3～4 the tunnel, promptly following stream, intermediate flow passage and top stream, wherein, intermediate flow passage is 1～2 the tunnel.Different shunting streams is not connected.The wind pushing form of cabinet type air conditioner indoor set generally adopts the blowing mode, above heat exchanger is arranged on, below centrifugal fan is provided with, centrifugal fan from following to up-draught.Owing to heat exchanger be obliquely installed and following windage big above reasons such as windage is little, in air-supply process upwards, make the air quantity that stream is accepted above the heat exchanger big, and the air quantity that following stream is accepted is little.Because top stream heat-exchange capacity is strong; And following stream heat-exchange capacity is poor, and for guaranteeing the heat exchanger shunting evenly, general top stream U type pipe is few; Following stream U type pipe is many, to strengthen heat exchange area.Because the air quantity that upper and lower stream is accepted differs greatly, cause the refrigerant pressure of the upper and lower stream of heat exchanger to fall inhomogeneous, refrigerant is in each road loss of flow difference, the refrigerant loss of each stream is unbalanced, cause the whole heat exchange efficiency of heat exchanger on the low side, thereby make floor air conditioner Energy Efficiency Ratio (EER) on the low side, can't satisfy efficient cabinet-type air conditioner design requirement.
How overcoming the deficiency of above-mentioned existence, then is the design problem that the present invention faced.
Summary of the invention
The invention provides a kind of indoor jump tube type heat exchanger in packaged air conditioner, it can solve problems such as the heat exchange efficiency that prior art exists is lower, and EER is on the low side.
In order to reach the purpose that solves the problems of the technologies described above, technical scheme of the present invention is, the indoor jumping tubing heat exchanger of a kind of cabinet air-conditioner, it comprises feed tube group, drain pipe group, following stream, intermediate flow passage and top stream is characterized in that: following stream to the small part pipeline and above stream to the small part pipeline connection.
In the present invention, also have following technical characterictic: the outlet of following stream is communicated to top stream by jumping pipe.
In the present invention, also have following technical characterictic: the import of following stream is communicated with the feed tube group, below the outlet of stream be communicated to the inlet tube of top stream by jumping pipe, above the outlet of stream be communicated with the drain pipe group.
In the present invention, also have following technical characterictic: the intermediate flow passage inlet tube is communicated with the feed tube group; The intermediate flow passage outlet is communicated with the drain pipe group.
In order to change the existing unbalanced problem of heat exchanger above and below stream refrigerant loss, the present invention directly is communicated to top stream with following stream, the above and below stream is circulated mutually, thereby form the blowing amount of accepting on each road and be tending towards balanced, and then upper and lower stream pressure is fallen reach unanimity, near identical, the whole heat exchange efficiency of heat exchanger improves refrigerant at each road loss of flow, EER improves, thereby has satisfied the designing requirement of efficient cabinet-type air conditioner.
Advantage is: under the condition of same power consumption, can increase the hot and cold amount of about 60～100w, improve indoor heat converter efficient simultaneously.

The specific embodiment
Embodiment, referring to Fig. 1, heat exchanger 9 is divided into three the tunnel, above stream 10, intermediate flow passage 11 and following stream 12.Feed tube group 5 is divided into two groups, and one group of inlet tube with following stream 12 is communicated with; Another group is communicated with the inlet tube of intermediate flow passage 11.
Two outlet 12-1 of following stream 12 are by directly being communicated with the top stream inlet tube 10-1 of top stream 10 by double bounce pipe 8.Top flowing path outlet pipe 10-2 is communicated with drain pipe group 7.
During work, following stream 12 and top stream 10 refrigerants flow to route and are, feed tube group 5 → following stream inlet tube 12-2 → following stream 12 → following flowing path outlet pipe 12-1 → jumping pipe 8 → top stream inlet tube 10-1 → top stream 10 → top flowing path outlet pipe → drain pipe group 7.
According to the design needs, below stream 12 can be the part pipeline of part pipeline and top stream 10 or whole pipeline connections, also can be part pipeline or whole pipeline connection of following stream 12 whole pipelines and top stream 10.
By changing the flow direction of refrigerant, make following stream 12 be flowed directly to top stream 10, thereby the air quantity that each stream is accepted is balanced substantially, the EER of heat exchanger 9 is improved, and improved whole heat exchange efficiency.
Certainly, the present invention is not limited to above-mentioned example, and in design concept essential scope of the present invention, the present invention also has many variations, and remodeling adds or replacement, also all belongs to protection scope of the present invention.
