Wherein, the third fan 11 may adopt a variable frequency fan. Here, the third heat exchanger 4 also corresponds to an evaporator, for example, an evaporator composed of a coil and fins provided on the coil, and the specific structure thereof will not be described in detail.
In a specific embodiment, the third fan 11 is disposed at the air outlet of the third heat exchanger 4, and can be used for forcibly discharging the air flowing into the third heat exchanger 4 through the high-speed rotation of the fan blades, so that the air in the driving area and the third heat exchanger 4 perform forced convection heat transfer, i.e., the flow rate of the air in the driving area entering and exiting the third heat exchanger 4 is accelerated, the air can more quickly complete circulation, so that the low-temperature working medium flowing in the third heat exchanger 4 can more quickly take away the heat in the driving area, thereby improving the heat exchange effect and efficiency of the second heat exchanger 3, and enhancing the refrigeration effect on the driving area.
In the present embodiment, the fourth heat exchanger 5 is provided with a first passage 51 and a second passage 52.
Specifically, one end of the first passage 51 is communicated with the third throttling device 8 through the port a of the fourth heat exchanger 5, and the other end of the first passage 51 is communicated with the port B of the compressor 1 through the port B of the fourth heat exchanger 5, so that the low-temperature working medium can flow into the first passage 51 from the port a of the fourth heat exchanger 5, and the working medium flows out of the first passage 51 from the port B of the fourth heat exchanger 5 after heat exchange.
As shown in fig. 2, fig. 2 is a schematic diagram of a system module according to another embodiment of the present invention (in the figure, solid arrows indicate a cooling circulation path of a working medium, and dotted arrows indicate a heating circulation path of the working medium).
In another embodiment, the present invention provides a vehicle with a passenger space and a driving area that are not only required to be cooled but also required to be heated (the battery generally does not have a heating requirement) in consideration of the actual use of the vehicle. In view of the above, the reversing device 12 is further added in this embodiment, so that the flow path switching of the high-temperature and high-pressure working medium generated by the compressor 1 is realized through the action of the reversing device 12.
It should be noted that, the ports a and B may both represent inlets of the working medium, and may also represent outlets of the working medium, specifically, the inlet or the outlet is represented, which needs to be determined according to the actual flowing condition of the working medium.
Specifically, the reversing device 12 has at least four ports, such as a four-way valve or a two-position four-way reversing valve, and the four ports can be respectively set as port a, port B, port C, and port D for the inflow and outflow of the working medium. Wherein, the port A of the reversing device 12 is communicated with the port A of the compressor 1, the port B of the reversing device 12 is communicated with the port A of the first heat exchanger 2, the port C of the reversing device 12 is communicated with the port B of the compressor 1, and the port D of the reversing device 12 is respectively communicated with the port B of the second heat exchanger 3, the port B of the third heat exchanger 4 and the port B of the fourth heat exchanger 5. The port B of the first heat exchanger 2 is also communicated with the port a of the second heat exchanger 3, the port a of the third heat exchanger 4 and the port a of the fourth heat exchanger 5.
The reverser 12 has at least two stations or two operating states, different stations or two operating states representing different communication states of the four ports thereof.
When the reversing device 12 works in the first station, the port a is connected to the port B, and the port C is connected to the port D. At this time, the high-temperature working medium output by the compressor 1 through the port a and the port B of the reversing device 12 and the port a of the first heat exchanger 2 flows into the first heat exchanger 2, then the first heat exchanger 2 outputs low-temperature working medium to the outside through the port B thereof, a part of the low-temperature working medium flows into the second heat exchanger 3 through the port a of the second heat exchanger 3, a part of the low-temperature working medium flows into the third heat exchanger 4 through the port a of the third heat exchanger 4, a part of the low-temperature working medium flows into the fourth heat exchanger 5 through the port a of the fourth heat exchanger 5, then the second heat exchanger 3 outputs normal-temperature working medium through the port B thereof, the third heat exchanger 4 outputs normal-temperature working medium through the port B thereof, and the fourth heat exchanger 5 outputs normal-temperature working medium through the port B thereof, and the normal-temperature working medium flows back into the compressor 1 through the port D, the port C and the port B of the reversing device 12, thereby completing the refrigeration cycle.
When the reversing device 12 works in the second station, the port a is connected to the port D, and the port B is connected to the port C. At the moment, a high-temperature and high-pressure working medium generated by the compressor 1 passes through the port A of the compressor 1, the port A of the reversing device 12 and the port D, a part of the working medium flows into the second heat exchanger 3 through the port B of the second heat exchanger 3, a part of the working medium flows into the third heat exchanger 4 through the port B of the third heat exchanger 4, the working medium output by the second heat exchanger 3 through the port A and the working medium output by the third heat exchanger 4 through the port A both flow into the first heat exchanger 2 through the port B of the first heat exchanger 2, and the working medium output by the first heat exchanger 2 through the port A flows back into the compressor 1 through the port B and the port C of the reversing device 12 and the port B of the compressor, so that the heating cycle is completed.
In the process of heating cycle (such as heat pump heating), high-temperature and high-pressure working media can enter the second heat exchanger 3 and the third heat exchanger 4 at the same time, heat is transferred to the second heat exchanger 3 and the third heat exchanger 4, and then the heat is respectively radiated to a passenger space and a driving area through the second heat exchanger 3 and the third heat exchanger 4, so that the passenger space and the driving area are respectively heated. At this time, the second and third fans 10 and 11 may still be kept in operation to rapidly dissipate heat to the entire passenger space or driving area. The high-temperature and high-pressure working medium passes through the second heat exchanger 3 and the third heat exchanger 4 to form a normal-temperature and high-pressure working medium, and then is subjected to pressure reduction through the first throttling device 6 and the second throttling device 7 to form a low-temperature and normal-pressure working medium.
In addition, considering that the battery generally has no heating requirement, in order to prevent the high-temperature and high-pressure working medium from entering the fourth heat exchanger 5, the flow direction control device 13 is further provided between the port B of the fourth heat exchanger 5 and the port D of the reversing device 12 in the present embodiment. Specifically, the flow direction control device 13 may employ a check valve.
