Embodiment 1

[0050] This embodiment provides a system for a dual-purpose vehicle-mounted refrigerator for cooling and heating. For a schematic structural diagram of a specific embodiment, refer to figure 1 , including a 12V input power supply, and also includes a processing module 1, the control input terminal of the processing module 1 is connected to the control output terminal of the control module 6, and the solenoid valve output terminal of the processing module 1 is connected to the control input terminal of the four-way solenoid valve 2 , the four-way solenoid valve 2 is connected to the two-way pipeline of the compressor 3, the evaporator interface of the four-way solenoid valve 2 is connected to the solenoid valve interface of the evaporator 4, the condenser interface of the evaporator 4 is connected to the evaporator of the condenser 5 The interface pipeline is connected, the solenoid valve interface of the condenser 5 is connected with the condenser interface pipeline of the four...

Embodiment 2

[0066] On the basis of specific embodiment 1, this embodiment also provides a system for a dual-purpose vehicle-mounted refrigerator for cooling and heating. For a schematic structural diagram of a specific embodiment, see Figure 4 , including a 24V input power supply, and also includes a temperature monitoring module 7 for monitoring the internal temperature of the car refrigerator, and the temperature monitoring module 7 is connected to the processing module 1 for signals.

[0067] Wherein, the set temperature is pre-set by the user through the control module and stored by the processing module. In the cooling mode, when the temperature in the refrigerator is higher than the set temperature and reaches a corresponding value (for example, 3°C), the processing module 6 starts the compressor; in the heating mode, when the temperature in the refrigerator is lower than the set temperature and reaches a corresponding value (for example, 3 °C), the processing module 6 starts the c...

Embodiment 3

[0075] see Figure 5 Shown is the system structure diagram of the dual-purpose vehicle-mounted refrigerator for cooling and heating in this embodiment, and on the basis of Embodiment 1, it also includes a condensing fan 8 . The condensing fan 8 is signal-connected to the processing module 1 , and the air outlet faces the condenser 5 . When the vehicle-mounted refrigerator is in the cooling mode, the processing module 1 sends a start command to the condensing fan 8, and the condensing fan 8 starts; when the vehicle-mounted refrigerator is in the heating mode, the processing module 1 sends a shutdown command to the condensing fan 8, and the condensing fan 8 is turned off.

Abstract

The invention belongs to the field of vehicle-mounted refrigerators and relates to a control system and method for a vehicle-mounted refrigerator with the dual purposes of refrigeration and heating. The control system comprises a control module. The control module is in signal connection with a processing module. The processing module is in signal connection with a four-way electromagnetic valve. The control system further comprises a compressor, an evaporator and a condenser. The compressor is in signal connection with the processing module. The four-way electromagnetic valve is in two-way pipeline connection with the compressor. An evaporator connector of the four-way electromagnetic valve is in pipeline connection with an electromagnetic valve connector of the evaporator. A condenser connector of the evaporator is in pipeline connection with an evaporator connector of the condenser. An electromagnetic valve connector of the condenser is in pipeline connection with a condenser connector of the four-way electromagnetic valve. The air circulation direction can be changed in the same system by controlling the four-way electromagnetic valve, so that a refrigeration mode and a heating mode is switched; and in addition, the size of the vehicle-mounted refrigerator cannot be increased, and the storage space cannot be reduced.

Description

technical field [0001] The invention belongs to the field of vehicle-mounted refrigerators, and relates to a control system and a control method for a dual-purpose vehicle-mounted refrigerator for heating and cooling. Background technique [0002] As the most common choice for people to travel nowadays, cars often carry a lot of food when traveling long distances or going out for fun. If the temperature of the food carried is required, a car refrigerator will be required for storage. Most of the car refrigerators now only have a single cooling function, which cannot meet the needs of users when hot drinks are needed in winter. For this, some car refrigerators already have a heating function, but their heating and cooling functions are independently completed by two systems. Such car refrigerators are usually huge in size, which is very inconvenient for users to carry. If the volume is similar to that of an ordinary car refrigerator, two systems are set at the expense of t...
