Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides an indoor unit of an air conditioner, which comprises a first condenser 31, a second condenser 32 and an outdoor evaporator 34, wherein the outdoor evaporator 34, the first condenser 31 and the second condenser 32 are arranged in parallel, and inlets of the first condenser 31 and the second condenser 32 are connected with an outlet of a compressor.
Specifically, the outdoor evaporator 34, the first condenser 31 and the second condenser 32 are arranged in parallel, and when the outdoor evaporator 34, the first condenser 31 and the second condenser 32 are all operated, the outdoor evaporator 34 provides corresponding energy for the first condenser 31 and the second condenser 32, so that the heat exchange efficiency of the condensers is improved. The first condenser 31 and the second condenser 32 may be turned on as needed to adjust cooling or heating efficiency of the air conditioner. Taking the heating mode as an example, the first condenser 31 and the second condenser 32 absorb heat of ambient air, and the outdoor evaporator 34 releases heat, and compared with a single condenser, the outdoor evaporator 34 provides more heat for the first condenser 31 and the second condenser 32, thereby improving the heating efficiency of the indoor unit; when the indoor temperature is higher, one of the condensers can be turned off to adjust the heating efficiency of the indoor unit. Similarly, in the cooling mode, the first condenser 31 and the second condenser 32 release heat to the outside, the outdoor evaporator 34 absorbs heat of the surrounding air, and the outdoor evaporator 34 provides more cooling capacity to the first condenser 31 and the second condenser 32, thereby further improving the cooling efficiency of the indoor unit.
In the outdoor unit of an air conditioner according to the embodiment of the present invention, the outdoor evaporator 34 provides energy to the first condenser 31 and the second condenser 32, so as to improve heat exchange efficiency of the condensers and improve cooling or heating efficiency, and meanwhile, the outdoor unit of an air conditioner includes the first condenser 31 and the second condenser 32, so that working conditions of the two condensers can be conveniently adjusted according to indoor temperature conditions.
On the basis of the above embodiment, the outdoor unit of an air conditioner further includes an outdoor fan 35. The outdoor evaporator 34, the first condenser 31 and the second condenser 32 are all located on the leeward side of the outdoor fan 35, and the outdoor evaporator 34 is located on the windward side of the first condenser 31 and the second condenser 32. When the outdoor evaporator 34, the first condenser 31 and the second condenser 32 are operated, the air flows through the outdoor evaporator 34, the first condenser 31 and the second condenser 32 after passing through the outdoor fan 35. Taking the heating mode as an example, the outdoor evaporator 34 releases heat, the ambient air is primarily heated by the heat released by the outdoor evaporator 34 and then supplied to the first condenser 31 and the second condenser 32, and the heat released by the outdoor evaporator 34 is blown to the first condenser 31 and the second condenser 32 by the air flow in the air flow flowing process, so that the heat exchange efficiency of the condensers is improved, and the heating efficiency of the air conditioner is further improved. Similarly, in the cooling mode, the outdoor evaporator 34 absorbs heat from the ambient air, and the cold energy released from the outdoor evaporator is blown to the first condenser 31 and the second condenser 32 during the airflow flowing process, thereby improving the working efficiency of the first condenser 31 and the second condenser 32. The arrangement mode can enable the first condenser 31 and/or the second condenser 32 to more fully utilize the cold or heat quantity provided by the outdoor evaporator, and improve the refrigeration and heating efficiency of the air conditioner. It can be understood that, regardless of whether one of the first condenser 31 and the second condenser 32 is operated or both of the first condenser 31 and the second condenser 32 are operated, the outdoor evaporator can supply corresponding energy in the heating or warming mode, thereby improving the operation efficiency of the condensers.
Wherein, the outdoor fan 35 is an axial fan. The blades in the axial flow fan push air to flow in the same direction as the shaft, so that arrangement of all parts in the outdoor unit of the air conditioner is facilitated.
On the basis of any one of the above embodiments, the communication pipeline between the outlets of the first condenser and the second condenser and the expansion valve is respectively provided with a stop valve. And a second stop valve is arranged at the outlet of the outdoor evaporator. The second stop valve is used for controlling the connection and disconnection of the communication passage between the outdoor evaporator and the indoor evaporator. When the second stop valve is in a closed state, the outdoor evaporator stops running, and the structure is not different from that of the traditional air conditioner; when the second stop valve is in the open mode, the outdoor evaporator operates, and compared with the traditional air conditioner, the refrigerating and heating efficiency can be effectively improved.
It is understood that the stop valves may be disposed on the connection lines between the inlets of the first condenser and the second condenser and the compressor. Similarly, a second shutoff valve is provided at the inlet of the outdoor evaporator.
The air conditioner outdoor unit provided by the embodiment of the invention comprises a case, a first condenser, a second condenser, an axial flow fan and an outdoor evaporator, wherein the axial flow fan, the outdoor evaporator and the condenser are sequentially arranged in the case. The outdoor evaporator, the first condenser and the second condenser are located at a lower air inlet of the axial flow fan, and the outdoor evaporator provides energy for the first condenser and the second condenser when the air conditioner refrigerates or heats, so that refrigeration and heating efficiency of the air conditioner is improved. The two ends of the first condenser and the second condenser are respectively connected with the compressor and the expansion valve, a stop valve is arranged between each condenser and the expansion valve, and the stop valves can control the on-off of pipelines connected with the corresponding condensers. Both ends of the outdoor evaporator are connected to an inlet of the compressor and an outlet of the expansion valve, respectively, so that the outdoor evaporator, the first condenser and the second condenser are arranged in parallel.
The structure of the air conditioner provided by the present invention will be described with reference to fig. 1.

Since the first condenser 31 and the second condenser 32 are provided in parallel, the indoor evaporator 10, the compressor 20, the first condenser 31, and the expansion valve 40 form a first circulation path, and the indoor evaporator 10, the compressor 20, the second condenser 32, and the expansion valve 40 form a second circulation path. The two circulation paths can be operated synchronously or alternatively. One end of the outdoor evaporator 34 is connected to an inlet of the compressor 20, and the other end of the outdoor evaporator 34 is connected to an outlet of the expansion valve 40.
Wherein, the outlets of the first condenser 31 and the second condenser 32 are respectively provided with a stop valve 33, and the corresponding condenser is controlled to operate or close by controlling the opening and closing of the stop valve 33.
