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 condenser, an outdoor fan and an outdoor evaporator, wherein the outdoor evaporator and the condenser are arranged in parallel, a second stop valve is arranged at the outlet of the outdoor evaporator, and the inlet of the condenser is connected with the outlet of a compressor so as to be driven by the compressor to enter a refrigerant in the condenser.
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 the closed state, the outdoor evaporator stops operating, and is not different from the structure of the traditional air conditioner.
Specifically, the outdoor evaporator and the condenser are arranged in parallel, when the outdoor evaporator and the condenser both operate, the refrigerant discharged from the indoor evaporator is distributed to the outdoor evaporator and the condenser, taking a heating mode as an example, the condenser absorbs the heat of the surrounding air, and the outdoor evaporator releases the heat, compared with a single condenser, the outdoor evaporator provides more heat for the condenser, so that the heating efficiency of the indoor unit is improved. Similarly, in the cooling mode, the condenser releases heat to the outside, the outdoor evaporator absorbs the heat of the surrounding air, and the outdoor evaporator provides more cold for the condenser, so that the cooling efficiency of the indoor unit is further improved.
On the basis of the above embodiment, the outdoor evaporator and the condenser are both positioned on the leeward side of the outdoor fan, and the outdoor evaporator is positioned on the windward side of the condenser. When the outdoor evaporator and the condenser operate, airflow passes through the outdoor evaporator and then the condenser after passing through the outdoor fan. Taking a heating mode as an example, the outdoor evaporator releases heat, ambient air is primarily heated by the heat released by the outdoor evaporator through the outdoor evaporator and then is absorbed by the condenser, and the heat released by the outdoor evaporator is blown to the condenser by airflow in the airflow flowing process, so that the heating efficiency is improved. Similarly, in the refrigeration mode, the outdoor evaporator absorbs the heat of the ambient air, and the cold energy released by the outdoor evaporator is blown to the condenser in the air flow flowing process, so that the working efficiency of the condenser is improved. The arrangement mode can make the condenser more fully utilize the cold or heat quantity provided by the outdoor evaporator, and improve the refrigeration and heating efficiency of the air conditioner.
Wherein, the outdoor fan 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.
The air conditioner outdoor unit provided by the embodiment of the invention comprises a case, a 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 and the condenser are positioned at the lower air inlet of the axial flow fan, and the outdoor evaporator provides energy for the condenser when the air conditioner refrigerates or heats, so that the refrigeration and heating efficiency of the air conditioner is improved. The two ends of the condenser are respectively connected with the compressor and the expansion valve, and the two ends of the outdoor evaporator are respectively connected with the inlet of the compressor and the outlet of the expansion valve, so that the outdoor evaporator and the condenser are arranged in parallel.
The structure of the air conditioner provided by the present invention will be described with reference to fig. 1.
Fig. 1 is a schematic structural diagram of an air conditioner provided by the present invention. As shown in fig. 1, the air conditioner includes an indoor unit of an air conditioner and an outdoor unit of an air conditioner as described above. The indoor unit of the air conditioner comprises an indoor evaporator 10, the air conditioner also comprises a compressor 20 and an expansion valve 40, the indoor evaporator 10, the compressor 20, a condenser 30 and the expansion valve 40 are sequentially connected, a first stop valve 50 is installed on a communication pipeline between the expansion valve 40 and the indoor evaporator 10, and a second stop valve 60 is installed on a communication pipeline between an outdoor evaporator 31 and the indoor evaporator 40.
In this air conditioner, an interior evaporator 10, a compressor 20, a condenser 30, and an expansion valve 40 are connected in order to form a refrigerant circulation path. The inlet of the outdoor evaporator 31 is connected with the inlet of the compressor 20, the outlet of the outdoor evaporator 31 is connected with the outlet of the expansion valve 40, the outdoor evaporator 31 is connected with the condenser 30 in parallel, and the condenser 30 is provided with sufficient energy to provide heating and cooling performance of the air conditioner.
In addition to the above-described embodiment, the inlet of the outdoor evaporator 31 communicates with the outlet of the indoor evaporator 10, the outlet line of the second cutoff valve 60 communicates with the inlet line of the first cutoff valve 50, and the expansion valve 40 is installed at the outlet of the condenser 30 to control the flow rate of the refrigerant flowing from the condenser 30 to the indoor evaporator 10. The second cut-off valve 60 is used only to control the opening and closing of the passage connected to the outdoor evaporator 31. The first cut-off valve 50 is used to control the opening and closing of the passage connected to the indoor evaporator 10; when the first cutoff valve 50 is closed, both the outdoor evaporator 31 and the condenser 30 are disconnected from the indoor evaporator 10. The expansion valve 40 and the compressor 20 are used only to regulate the communication line connected to the condenser 30.
The invention also provides an air conditioner control method for controlling the air conditioner. Fig. 2 is a schematic flow chart of an air conditioner control method provided by the invention. As shown in fig. 2, the air conditioner control method includes:
step 210: acquiring indoor temperature in a refrigerating mode or a heating mode; if the difference value of the indoor temperature and the set temperature is larger than a first preset value, controlling the indoor evaporator, the outdoor evaporator and the condenser to synchronously operate, and if the difference value of the indoor temperature and the set temperature is not larger than the first preset value, controlling the outdoor evaporator to stop operating and controlling the indoor evaporator and the condenser to continuously operate;
step 220: and in the defrosting mode, the indoor evaporator is controlled to stop running, and the outdoor evaporator and the condenser are controlled to run.
The steps 210 and 220 are only used for distinguishing different control operations, and the control sequence is not limited. In the cooling and heating modes, when the indoor temperature of the outdoor evaporator is far lower than the set temperature, the outdoor evaporator is started, and the heat exchange efficiency of the condenser is improved, so that the cooling and heating efficiency of the indoor unit is improved, and the cooling and heating are assisted. In the defrost mode, the outdoor evaporator operates to generate heat to assist in defrosting.
Wherein, the first preset value can be 3 degrees or 6 degrees, or any value between 3 degrees and 6 degrees. The set temperature is the target temperature when the air conditioner works and can be manually adjusted or set according to an automatic adjusting program of the air conditioner.
