Detailed Description

All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
As shown in fig. 1, an air conditioner 1 according to an embodiment of the present invention includes: the air conditioner includes a compressor 10, an indoor heat exchanger 40, an outdoor heat exchanger 50, a four-way valve 60, a first heating module 20, a second heating module 30, and a throttle device 70.
In terms of expansion, the compressor 10, the four-way valve 60, the indoor heat exchanger 40, the throttling device 70 and the outdoor heat exchanger 50 are sequentially communicated, and the compressor 10 comprises an air inlet end 10a and an air outlet end 10b; the first heating module 20 includes a first air inlet and a first air outlet, the first air outlet being connected to the air inlet end 10 a; the second heating module 30 includes a second air inlet and a second air outlet, the second air inlet being connected to the air outlet 10b; the four-way valve 60 includes a first port 60a, a second port 60b, a third port 60c, and a fourth port 60d, the first port 60a being in communication with the indoor heat exchanger 40, the second port 60b being in communication with the outdoor heat exchanger 50, the third port 60c being in communication with the first air inlet, the fourth port 60d being in communication with the second air outlet.
In the heating state, the first port 60a and the fourth port 60d communicate, the second port 60b and the third port 60c communicate, and in the cooling state, the second port 60b and the fourth port 60d communicate, and the first port 60a and the third port 60c communicate.
That is, during cooling, the refrigerant in the outdoor heat exchanger 50 is in a high-temperature and high-pressure state, and releases heat to the outdoor air, and the refrigerant in the indoor heat exchanger 40 is in a low-temperature state, and the indoor temperature is lowered by absorbing the heat of the indoor air; in heating, the refrigerant with high temperature and high pressure flows out into the indoor heat exchanger 40 through the compressor 10 to perform condensation heat release, so that the indoor temperature is raised, the liquid refrigerant condensed by the indoor heat exchanger 40 is throttled into a refrigerant with low temperature and low pressure by the throttle device 70, and the refrigerant enters the outdoor heat exchanger 50 to perform evaporation heat absorption and then returns to the compressor 10.
Therefore, during heating, the first heating module 20 can heat the refrigerant entering the compressor 10 through the air inlet end 10a, and primarily heat the refrigerant with low temperature and low pressure, so that the temperature of the refrigerant entering the compressor 10 is increased, the time for the compressor 10 to compress the refrigerant with low temperature and low pressure into the refrigerant with high temperature and high pressure is shortened, the second heating module 30 can further heat the refrigerant flowing out through the air outlet end 10b, so that the refrigerant with high temperature and high pressure is further heated, the temperature of the air discharged by the compressor 10 is raised, and the compression time of the compressor 10 is shortened on the premise of guaranteeing the temperature of the refrigerant supplied to the indoor heat exchanger 40, so that the rapid heating effect of the air conditioner 1 in the startup stage under the low temperature environment is realized.
According to the air conditioner 1 of the embodiment of the invention, the refrigerants entering the compressor 10 and flowing out of the compressor 10 can be heated through the first heating module 20 and the second heating module 30, so that the rising rate of the tube temperature of the indoor heat exchanger 40 is improved, the tube temperature of the indoor heat exchanger 40 can reach the condition that the indoor fan is started as soon as possible, hot air is sent out to the indoor, and the heating comfort of a user in the initial starting stage of cold weather is improved.
As shown in fig. 2 and 3, according to the air conditioner 1 of the embodiment of the present invention, each of the first heating module 20 and the second heating module 30 includes a housing, a heat exchange tube 22, and at least one heating body 23.
Specifically, the housing defines a mounting cavity, the heat exchange tube 22 is disposed in the mounting cavity, the heat exchange tube 22 defines a refrigerant channel therein, and the heating element 23 is disposed in the mounting cavity. The refrigerant channel is used for supplying a refrigerant to flow through for heat exchange, so that the temperature of the refrigerant is raised, and the heating element 23 is used for heating the heat exchange tube 22.
That is, in the heat exchange tube 22 connected to the air inlet 10a of the compressor 10, the low-temperature low-pressure refrigerant flowing in through the outdoor heat exchanger 50 flows into the compressor 10 through the refrigerant passage, and when the low-temperature low-pressure refrigerant is in the heat exchange tube 22, heat exchange is performed by contacting with the tube wall of the heat exchange tube 22, thereby raising the temperature of the refrigerant; in the heat exchange tube 22 connected to the exhaust end 10b of the compressor 10, the high-temperature and high-pressure refrigerant flowing out from the exhaust end 10b of the compressor 10 enters the indoor heat exchanger 40 through the refrigerant channel, and contacts with the tube wall of the heat exchange tube 22 to generate heat exchange when the high-temperature and high-pressure refrigerant flows through the heat exchange tube 22, so that the temperature of the refrigerant is further raised.
In some embodiments, the heat generating body 23 includes one, and one heat generating body 23 is provided at the left or right side of the heat exchange tube 22.
As shown in fig. 2 and 3, the heating elements 23 include two heating elements 23, which are respectively located at both sides of the heat exchange tube 22 and spaced apart from the heat exchange tube 22. Compared with the direct contact between the heat exchange tube 22 and the heat source, the heat conduction of each part of the heat exchanger can be more uniform. The heating element 23 includes an electric heating rod, and of course, the heating element 23 may be an electromagnetic generator.
As shown in fig. 2 and 3, the heat exchange tube 22 is configured as a tube extending along a straight line, and in other embodiments, the heat exchange tube 22 may also be configured as a tube extending in a bending manner, so that the length of time that the refrigerant flows through the heat exchange tube 22 can be appropriately prolonged, thereby further increasing the temperature of the refrigerant, and it should be noted that the arrangement needs to be calculated reasonably.
In some embodiments, the heating body 23 includes a resistance wire wound around the heat exchange tube 22 to heat the heat exchange tube 22.
In some embodiments, the first heating module 20 and the second heating module 30 further include a heat conducting layer 24 and a heat insulating layer 25, the heat conducting layer 24 is filled in the installation cavity, and the heat insulating layer 25 is wrapped outside the housing. The heat conducting layer 24 is used for transferring heat to the heat exchange tube 22, so that heat exchange between the heat exchange tube 22 and the heating body 23 is more uniform.
In some embodiments, the first temperature sensor 26 is disposed outside the housing of the first heating module 20, and the second temperature sensor 31 is disposed outside the housing of the second heating module 30. The first temperature sensor 26 is configured to detect the temperature of the first heating module 20, substantially the temperature of the heat exchange tube 22, and the second temperature sensor 31 is configured to detect the temperature of the second heating module 30, substantially the temperature of the heat exchange tube 22, so that the temperatures of the first heating module 20 and the second heating module 30 can be adjusted by the first temperature sensor 26 and the second temperature sensor 31 being able to feed back to the main control unit of the air conditioner 1.
Wherein the first heating module 20 and the second heating module 30 are independently controlled, that is, the on and off of the first heating module 20 does not affect the on and off of the second heating module 30.
As shown in fig. 2 and 3, the first and second heating modules 20 and 30 are juxtaposed and the housings are connected, so that the assembly connection of the first and second heating modules 20 and 30 with the compressor 10 can be simplified.
As shown in fig. 1, the air conditioner 1 according to the embodiment of the present invention further includes a switching valve 80 and a communication pipe, the indoor heat exchanger 40 includes a first sub heat exchanger 41 and a second sub heat exchanger 42 connected in parallel, the second sub heat exchanger 42 is connected in series with the communication pipe, the communication pipe is disposed between the four-way valve 60 and the second sub heat exchanger 42, the switching valve 80 is disposed on the communication pipe, and the switching valve 80 is used for controlling on/off of the communication pipe. The first sub heat exchanger 41 and the second sub heat exchanger 42 are connected in parallel, so that the refrigerant entering the indoor heat exchanger 40 is respectively distributed in the first sub heat exchanger 41 and the second sub heat exchanger 42, and the heat exchange capacity of the indoor heat exchanger 40 can be improved while the resistance of the refrigerant flowing is reduced.
