Preferably, the electronic expansion valves 4 and 9 are all-pass electronic expansion valves, and may be used as throttle elements or refrigerant passages.
The electric compressor 1, the internal condenser 2, the external heat exchanger 5 and the integrated liquid storage vapor-liquid separator 6 are connected in sequence, and the battery cooler 10 and the evaporator 12 are respectively connected between the electric compressor 1 and the integrated liquid storage vapor-liquid separator 6. The first electronic expansion valve 4 is connected between the external heat exchanger 5 and the internal condenser 2, the one-way valve 8 and the second electronic expansion valve 9 are sequentially connected between the battery cooler 10 and the integrated liquid storage vapor-liquid separator 6, the thermostatic expansion valve 11 with a stop function is connected between the evaporator 12 and the one-way valve 8, the first electromagnetic stop valve 3 is connected between the internal condenser 2 and the one-way valve 8, and the second electromagnetic stop valve 7 is connected between the electric compressor 1 and the integrated liquid storage vapor-liquid separator 6. The system is switched among a refrigeration mode, a heating mode, a demisting mode and a defrosting mode thereof through the switches of the first electronic expansion valve 4, the second electronic expansion valve 9, the thermostatic expansion valve 11 with a stop function, the first electromagnetic stop valve 3, the second electromagnetic stop valve 7 and the check valve 8.
The integrated liquid storage gas-liquid separator 6 comprises a cylinder 61, an inlet 62, an outlet 63, a ball valve mechanism 64, an internal air inlet pipe 65, an internal outlet pipe 66, a drying bag 67 and a filter screen 68, wherein one end of the cylinder 61 is connected with the inlet 62 and the outlet 63 respectively, the other end of the cylinder 61 is connected with the ball valve mechanism 64, the ball valve mechanism 64 extends into the cylinder 61, the ball valve mechanism 64 is connected with the internal air inlet pipe 65 and the internal outlet pipe 66 respectively, and the drying bag 67 is connected onto the internal outlet pipe 66. The filter net 68 is attached to the inner wall of the cylinder 61. Preferably, the refrigerant in the inner cavity of the cylinder body is filtered by a filter screen.
Wherein the integrated liquid storage gas-liquid separator 6 is switched between the liquid storage mode and the gas-liquid separator mode, preferably, the switching of different functions of the integrated liquid storage gas-liquid separator 6 is realized by a ball valve mechanism 64 arranged in the integrated liquid storage gas-liquid separator;
when the exterior heat exchanger 5 is in a refrigeration mode, the integrated liquid storage vapor-liquid separator 6 is switched to a liquid storage mode, and the ball valve mechanism 64 is respectively connected with the internal outlet pipe 66 and the internal cavity of the cylinder 61;
when the exterior heat exchanger 5 is in the heating mode, the integrated liquid-storage vapor-liquid separator 6 is switched to the vapor-liquid separator mode, and the ball valve mechanism 64 is connected to the inner outlet pipe 66 and the inner intake pipe 65, respectively.
More specifically, fig. 2 shows an external view of the integrated liquid-gas-liquid separator of the present invention, which is mainly composed of a cylinder 61, an inlet 62, an outlet 63, and a ball valve mechanism 64. The ball valve mechanism is used for controlling the working mode of the integrated liquid storage gas-liquid separator, namely, the integrated liquid storage gas-liquid separator works as a liquid storage device or a gas-liquid separator.
Fig. 3 and 4 show internal structural views of the integrated liquid-storage gas-liquid separator 6 when it operates as an accumulator or a gas-liquid separator, respectively. The interior of the integrated liquid-storage gas-liquid separator 6 mainly includes an internal intake pipe 65, an internal outlet pipe 66, a drying bag 67, a filter screen 68, and a spool portion of the ball valve mechanism 64.
When operating as an accumulator, as shown in fig. 3, after the refrigerant enters the chamber from the inlet 62, the inlet channel internal inlet pipe 65 for gaseous refrigerant is blocked by the valve element, and gaseous refrigerant at the top of the chamber cannot enter the internal outlet pipe 66. The liquid refrigerant enters the inner outlet pipe 66 through the opening on the right side of the valve element, so that the outlet 63 of the integrated accumulator-gas-liquid separator is the liquid refrigerant, thereby realizing the function of an accumulator.
When operating as a gas-liquid separator, as shown in fig. 4, the ball valve mechanism rotates so that the liquid refrigerant passage at the bottom of the cavity is blocked by the ball valve core, and therefore the liquid refrigerant cannot enter the inner outlet pipe 66. While at the same time the ball valve mechanism rotates so that the opening to the left of its spool opens, allowing gaseous refrigerant at the top of the chamber to enter the inner outlet pipe 66 through the inner inlet pipe 65 and eventually exit the outlet 63.
Example 2
When the system is in the cooling mode, as shown in fig. 5, the following is specific:
the first electronic expansion valve 4 is in a full-through state, the first electromagnetic stop valve 3 and the second electromagnetic stop valve 7 are both closed, the thermostatic expansion valve 11 with a stop function is opened, and the integrated liquid storage gas-liquid separator 6 is used as a liquid storage device. The second electronic expansion valve 9 is opened depending on whether battery cooling is required, closed if battery cooling is not required, opened if required and throttled down to reduce the pressure of the refrigerant. The high-temperature and high-pressure refrigerant flows out of the compressor 1, flows through the internal condenser 2 and the external heat exchanger 5 in sequence, exchanges heat with external air in the external heat exchanger 5 so as to dissipate heat to the external environment, and then passes through the integrated liquid storage gas-liquid separator 6, and the liquid refrigerant coming out of the integrated liquid storage gas-liquid separator 6 is divided into two paths: one path of the refrigerant passes through a thermal expansion valve 11 with a cut-off function, passes through an evaporator 12 after throttling and pressure reduction and exchanges heat with air in a vehicle so as to be refrigerated; the other path is throttled and depressurized by an electronic expansion valve 9, and then exchanges heat with a battery cooling liquid loop through a battery cooler 10 to cool the battery. The two paths of refrigerant are merged and then return to the inlet of the compressor 1 so as to realize circulation. In this mode, the air conditioning compartment temperature damper is fully cooled, so that the refrigerant does not exchange heat with the air in the vehicle while flowing through the interior condenser 2.
Example 3
When the system is in heating mode, as shown in fig. 6, the following is specific:
the first electronic expansion valve 4 is in a throttling state, the first electromagnetic stop valve 3 is closed, the second electromagnetic stop valve 7 is opened, the second electronic expansion valve 9 and the thermal expansion valve 11 with a stop function are both in a closed state, and the integrated liquid storage gas-liquid separator 6 is used as a gas-liquid separator. The high-temperature and high-pressure refrigerant flows out from the compressor 1, exchanges heat with air at the internal condenser 2 to heat the air in the vehicle, and the temperature air door of the air conditioning box is in a full-hot state at the moment. The refrigerant flows out of the condenser 2 in the vehicle, is throttled and depressurized by the first electronic expansion valve 4, exchanges heat with the air outside the vehicle in the heat exchanger 5 outside the vehicle to absorb the heat of the environment, and then enters the integrated liquid storage gas-liquid separator 6. After passing through the integrated liquid storage gas-liquid separator 6, the gaseous refrigerant directly enters the inlet of the compressor 1 through the second electromagnetic stop valve 7, thereby realizing circulation.
Example 4
When the system is in the demisting mode, as shown in fig. 7, the following is detailed:
the first electronic expansion valve 4 is in a throttling state, the first electromagnetic stop valve 3 and the second electromagnetic stop valve 7 are both opened, the second electronic expansion valve 9 is closed, the thermostatic expansion valve 11 with a stop function is in an opening state, and at the moment, the integrated liquid storage gas-liquid separator 6 works in a gas-liquid separator state. The refrigerant flows out from the compressor 1, exchanges heat with air at the internal condenser 2 to heat the air in the vehicle, and the temperature air door of the air conditioning box can be adjusted according to the requirement of heating capacity. The refrigerant is divided into two paths after coming out of the condenser 2 in the vehicle: one path of air passes through the first electromagnetic stop valve 3, is throttled and depressurized through a thermal expansion valve 11 with a stop function, and then exchanges heat with air entering a carriage in an evaporator 12 so as to realize cooling and dehumidification; the other path enters a heat exchanger 5 outside the vehicle after being throttled by a first electronic expansion valve 4, exchanges heat from the environment outside the vehicle to absorb heat, and then enters an integrated liquid storage gas-liquid separator 6. The gaseous refrigerant flowing out of the integrated liquid-storage gas-liquid separator 6 passes through the second electromagnetic shutoff valve 7, joins with the refrigerant flowing out of the evaporator 12, and returns to the inlet of the compressor 1 to realize circulation.
Example 5
When the system is in the heating mode as shown in fig. 6, the surface temperature of the exterior heat exchanger 5 is low, and therefore surface frosting may occur. When the frost formation is severe, a defrosting operation is required as shown in fig. 8. The method comprises the following specific steps:
in this mode, the first electronic expansion valve 4 is in a full-through state, the second electronic expansion valve 9 is in a throttling state, the first electromagnetic stop valve 3, the second electromagnetic stop valve 7 and the thermostatic expansion valve 11 with a stop function are all closed, and the integrated liquid storage gas-liquid separator 6 is used as a liquid storage device. The high-temperature and high-pressure refrigerant flows out of the compressor 1, exchanges heat with air in the vehicle at the condenser 2 in the vehicle to heat the air in the vehicle, and the temperature air door is adjusted according to the heat exchange quantity requirement. The refrigerant enters the exterior heat exchanger 5 after coming out of the interior condenser 2 and melts away the frost layer on the surface of the exterior heat exchanger 5 by heat. After flowing out of the exterior heat exchanger 5, the refrigerant is throttled and depressurized by the second electronic expansion valve 9, then exchanges heat with the cooling liquid loop in the battery cooler 10 to absorb heat in the cooling liquid, and then returns to the inlet of the compressor 1 to realize circulation.
