In an embodiment of the present invention, a modified air conditioning system based on an original vehicle air conditioning system is provided, as shown in fig. 1, including an original vehicle air conditioning system, an electric compressor 1 outside the original vehicle air conditioning system, a first communication pipeline 3, a second communication pipeline 4, a first three-way valve 5 and a second three-way valve 6, wherein the first communication pipeline 3 and the second communication pipeline 4 are preferably copper pipes and/or aluminum pipes; the original vehicle air conditioning system comprises an original vehicle compressor 71, a condenser 72, an expansion valve 73, an evaporator 74, a liquid storage tank 75 for storing liquid and a fan device 76, wherein the fan device 76 is used for blowing air and discharging air after the temperature of the air is changed by the evaporator 74, the inlet of the original vehicle compressor 71 is communicated with the outlet of the evaporator 74, preferably for throttling, the liquid entering the evaporator 74 and the gas discharged by the evaporator 74 both pass through the expansion valve 73, the outlet of the original vehicle compressor 71 is communicated with the inlet of the condenser 72, the outlet of the condenser 72 is communicated with the expansion valve 73 through the liquid storage tank 75, namely, copper pipes and/or aluminum pipes and/or high-pressure rubber pipes are adopted among the original vehicle compressor 71, the condenser 72, the liquid storage tank 75, the expansion valve 73 and the evaporator 74 to form a closed system.
The embodiment of the utility model provides an among the repacking air conditioning system, first three-way valve 5 sets up on the former car compressor 71's of former car air conditioning system the entry communicating pipe way, specifically, first three-way valve 5's first intercommunication mouth with former car compressor 71's entry intercommunication, first three-way valve 5's second intercommunication mouth and expansion valve 73's export intercommunication, first three-way valve 5's third intercommunication mouth is through the entry intercommunication of first intercommunication pipeline 3 with electric compressor 1. The first three-way valve 5 is used for controlling the communication between the inlet of the original vehicle compressor 71 and the outlet of the expansion valve 73 or controlling the communication between the inlet of the electric compressor 1 and the outlet of the expansion valve 73.
Similarly, the second three-way valve 6 is disposed on an outlet communication pipeline of an original vehicle compressor 71 of the original vehicle air conditioning system, specifically, a first communication port of the second three-way valve 6 is communicated with an outlet of the original vehicle compressor 71, a second communication port of the second three-way valve 6 is communicated with an inlet of the condenser 72, and a third communication port of the second three-way valve 6 is communicated with an outlet of the electric compressor 1 through the second communication pipeline 4. The second three-way valve 6 is used for controlling the communication between the outlet of the original vehicle compressor 71 and the inlet of the condenser 72 or controlling the communication between the outlet of the electric compressor 1 and the inlet of the condenser 72.
The electric compressor 1, the first three-way valve 5 and the second three-way valve 6 are respectively electrically connected with the output end of a control box 2 of the refitted air conditioning system, and the first three-way valve 5 and the second three-way valve 6 are controlled by the control box 2.
Besides, the control box 2 can detect a power line signal of the original vehicle compressor 71, and further, the electric compressor 1 and the original vehicle compressor 71 can only operate at most one at the same time, that is, before the electric compressor 1 is controlled to start, the control box 2 needs to first confirm that the power line signal of the original vehicle compressor 71 is 0 (that is, the original vehicle compressor 71 is in a non-start state), and only in a state where the original vehicle compressor 71 stops operating, the electric compressor 1 can start operating.
Based on the structure of the modified air conditioning system, the following two operation modes exist:
the first operation mode is that the first three-way valve 5 controls the communication between the inlet of the original vehicle compressor 71 and the outlet of the expansion valve 73, and the second three-way valve 6 controls the communication between the outlet of the original vehicle compressor 71 and the inlet of the condenser 72: when the refrigeration system works, the refrigerant circularly flows in the closed system in different states, and each cycle has four basic processes: 1. and (3) a compression process: the original vehicle compressor sucks the low-temperature and low-pressure refrigerant gas at the outlet of the evaporator, compresses the refrigerant gas into high-temperature and high-pressure gas and discharges the gas out of the compressor; 2. the heat dissipation process: the high-temperature and high-pressure superheated refrigerant gas enters a condenser, and is condensed into liquid due to the reduction of pressure and temperature, and a large amount of heat is discharged; 3. and (3) throttling process: the refrigerant liquid with higher temperature and pressure passes through the expansion device, the volume is increased, the pressure and temperature are sharply reduced, and the refrigerant liquid is discharged out of the expansion device in a mist shape (fine liquid drops); 4. and (3) heat absorption process: the atomized refrigerant liquid enters the evaporator, so that the boiling point of the refrigerant is much lower than the temperature in the evaporator, and the refrigerant liquid is evaporated into gas. During the evaporation process, a large amount of ambient heat is absorbed, and then the refrigerant vapor with low temperature and low pressure enters the compressor of the original vehicle. The above process is repeated to achieve the purpose of reducing the temperature of the air around the evaporator.
The second operation mode is that the first three-way valve 5 controls the inlet of the motor-driven compressor 1 to communicate with the outlet of the expansion valve 73, and the second three-way valve 6 controls the outlet of the motor-driven compressor 1 to communicate with the inlet of the condenser 72. On former car air conditioning system's basis promptly, when the user used electric air conditioner, the control box of electric compressor detects former car compressor earlier whether start, if former car compressor does not start, then the operation is opened to the electric compressor. The compressor of the original vehicle is replaced, the three-way valve closes the compressor of the original vehicle, and only the air conditioning system on the side of the electric compressor is started to realize refrigeration. As can be seen from figure 1, the system utilizes the original air conditioning system of the original vehicle, realizes refrigeration by matching with the electric compressor, uses the storage battery as a driving energy source, and the storage battery can be automatically charged in the starting and running process of the vehicle, so that the fully charged storage battery drives the electric compressor in the non-starting state of the vehicle, a user can freely use the air conditioner (the cost of the storage battery is not enough), and the control box is mainly responsible for controlling temperature regulation of starting and stopping of the compressor and detecting various faults. After the additional system is installed, the original vehicle air conditioner can still be used.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
