Abstract
The present invention relates to an outdoor machine of an air conditioner with two compressors and two systems, and comprises an outdoor machine shell, a first compressor, a second compressor, a first cycling pipeline, a second cycling pipeline and an outdoor heat exchanger, wherein, the first and the second cycling pipelines on the heat exchanger are respectively constituted an independent air conditioning system that can be operated individually together with the first and the second compressors; the first cycling pipeline and the second cycling pipeline are distributed on the entire outdoor heat exchanger at intervals. The original two heat exchangers are integrated into one heat exchanger, and the first cycling pipeline and the second cycling pipeline are arranged on the heat exchanger at intervals, so that when a single air conditioning system is operated, the heat exchanging area of the entire heat exchanger can be adequately used, and the heat exchanger of the system is free from staying at an idle status, thereby improving the heat exchanging efficiency.
Description
Technical field
The present invention relates to the air conditioner technical field, two compressors of particularly a kind of use, configuration two covers are independent can to divide the double-compressor of the air-conditioning system of open shop, the air-conditioner outdoor unit of dual system.
Background technology
The air conditioner of existing double-compressor, dual system generally all disposes the independent air-conditioning system that can divide open shop of two covers, at inner each compressor of air-conditioner outdoor unit separately heat exchanger is arranged all, and two heat exchangers are independent mutually.Like this, when air conditioner needs the single compressor independent operating, have only the heat exchanger that is connected with this compressor to play the heat exchange effect, another heat exchanger then is in idle state, causes the heat exchange efficiency of whole air conditioner not high.
Summary of the invention
The objective of the invention is shortcoming at above background technology, the air-conditioner outdoor unit of a kind of double-compressor, dual system is provided, it can be when only needing the single compressor independent operating, make full use of intrasystem heat exchanger, do not allow intrasystem heat exchanger that idle state is arranged, to improve the heat exchange efficiency of whole air conditioner.
Purpose of the present invention is realized by following technical proposals.
The present invention includes outdoor shell, first compressor, second compressor, first circulation line, second circulation line and outdoor heat exchanger, first circulation line on the heat exchanger, second circulation line constitute the independent air-conditioning system that can divide open shop with first compressor, second compressor respectively, and described first circulation line and second circulation line are distributed on the whole outdoor heat exchanger.
Above-mentioned outdoor heat exchanger is a cover overall structure.
Above-mentioned outdoor heat exchanger is specially the air-cooled tube wing-type structure.
Above-mentioned outdoor heat exchanger is a micro-channel heat exchanger.
Above-mentioned first circulation line and second circulation line distance spaced apart on heat exchanger is two heat exchanger tubes.
The detailed structure of its parts of the present invention, and operation principle is all identical with existing air conditioner with the course of work, is described no longer one by one.
The invention has the beneficial effects as follows: because the present invention merges into a cover heat exchanger with former two cover heat exchangers, first circulation line and second circulation line on the heat exchanger are spaced apart on heat exchanger, therefore when an independent cover air-conditioning system is moved, also can make full use of the heat exchange area of whole heat exchanger, can not allow intrasystem heat exchanger that idle state is arranged, thereby improve heat exchange efficiency.
Description of drawings
Fig. 1 is the off-premises station structural representation of existing double-compressor, dual system;
Fig. 2 is a structural representation of the present invention.
Omitted among the figure with the present invention and designed other irrelevant parts of main points.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further.
As shown in Figure 1, the air conditioner of existing double-compressor, dual system, the general independent air-conditioning system that can divide open shop of two covers that all disposes all has separately heat exchanger 4 and 5, two heat exchangers of heat exchanger independent mutually at the inside of air-conditioner outdoor unit housing 1 first compressor 2 and second compressor 3.Like this, when air conditioner needs the single compressor independent operating, have only the heat exchanger that is connected with this compressor to play the heat exchange effect, another heat exchanger then is in idle state.When for example first compressor 2 moves, have only heat exchanger 4 to play the heat exchange effect, heat exchanger 5 then is in idle state, causes the heat exchange efficiency of whole air conditioner not high.
As shown in Figure 2, the present invention includes outdoor shell 1, first compressor 2, second compressor 3, first circulation line 7, second circulation line 8 and outdoor heat exchanger 6, heat exchanger 6 is a cover overall structure, is specially the air-cooled tube wing-type structure, also can be micro-channel heat exchanger; First circulation line 7 on the outdoor heat exchanger 6, second circulation line 8 constitute the independent air-conditioning system that can divide open shop with first compressor 2, second compressor 3 respectively, described first circulation line 7 and second circulation line 8 are distributed on the whole outdoor heat exchanger 6, and distance spaced apart is two heat exchanger tubes.
In the present invention, first compressor 2 and 3 liang of cover systems of second compressor have separately the independently pipeline circulatory system, refrigerant fluid interchange in connected heat exchanger circulation line, because first circulation line 7 and second circulation line 8 of heat exchanger are distributed on the whole heat exchanger 6, when needs single compressor independent operating, no matter be first compressor 2 or second compressor, 3 independent operatings, whole outdoor heat exchanger 6 all participates in heat exchange, the idle phenomenon that heat exchanger can not occur, can make full use of the effective heat exchange area heat exchange of heat exchanger 6, thereby improve heat exchange efficiency.
