[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figs. 1-2 This utility model provides a technical solution: an integrated parking heating and cooling heat exchange device, including a parking body 1, a driver's cab 2, an in-vehicle evaporator 3, an original vehicle compressor 7, an engine 14, a fuel tank 15, and a water tank 11. One end of the in-vehicle evaporator 3 is connected to an expansion valve 4 and a low-pressure three-way valve 5. After the refrigerant flows out through the low-pressure three-way valve 5, it is divided into two paths. One path is connected to an electric compressor 6 for cooling when the vehicle is parked, and the other path is connected to the original vehicle compressor 7, which is carried by the parking body 1 and cools the vehicle while it is running. The output ends of the electric compressor 6 and the original vehicle compressor 7 are connected to a high-pressure three-way valve 8. The other end of the high-pressure three-way valve 8 is connected to an external condenser 9. When the vehicle is parked for cooling, a 12V parking parallel air conditioner is added. The parking parallel air conditioner connects an electric compressor 6 and the original vehicle compressor 7 in parallel to the original vehicle air conditioning system, so that the refrigerant can be circulated by the air conditioning compressor when the engine 14 is running, and can also be circulated by the electric compressor 6 when the engine 14 is not running, and the refrigerant is discharged from the original vehicle air duct.

[0022] A heater 10 is connected to one end of the fuel tank 15, a water pump 12 is connected to one end of the heater 10, an exhaust fan 13 is connected to the output end of the water pump 12, and a water tank 11 is connected to the other end of the heater 10. The exhaust fan 13 heats the gas generated by the water source heated by the heater 10 and then discharges it into the cab 2 for heating. After heat exchange, the water source is connected to the engine 14, thereby enabling the engine 14 to start hot and raising the temperature of the cab 2. The engine 14 is heated, preheated, and kept warm by adding a parking fuel heater 10. Its working principle is to use the vehicle's battery and fuel tank 15 to provide power and a small amount of fuel, connect them in series with the original vehicle for heating, and heat the circulating water of the engine 14 by burning gasoline, thereby enabling the engine 14 to start hot.

[0023] The parking body 1 has an external quick-connect socket and a power bank. The power bank provides power to the external devices, making it convenient to provide power to the external electrical equipment.

[0024] In this embodiment, the output end of the external condenser 9 is connected to the air intake duct in the parking cab 2 and to the original vehicle air duct to facilitate air outlet. The electric compressor 6 and the original vehicle compressor 7 are connected in parallel to the air conditioning system of the parking body 1.

[0025] In this embodiment, the water source that has been preheated in the engine 14 is pumped back to the water tank 11 by the water pump 12 to form a circulation, so that the water source with temperature can continuously preheat the engine 14 at low temperature, speed up the preheating and start-up of the engine 14, and reduce damage to the engine 14.

[0026] In this embodiment, the heater 10 is powered and supplied with a small amount of fuel by the battery and fuel tank 15 inside the parking body 1. The heater 10 provides heat by burning fuel and heats water for recycling. When electricity is needed, it can be powered by the battery inside the parking body 1 or by an external mobile power source.

[0027] The heater 10 is externally connected to an air intake filter 17 and a smoke exhauster 18, which are used to filter impurities in the air entering the heater 10, improve the service life of the heater 10, and also exhaust the smoke generated by combustion in the heater 10. The power bank is equipped with a 7.2 kWh power supply and is compatible with parallel air conditioning power. It weighs 50 kg and can be placed in the trunk. The weight is appropriate, easy to carry, and convenient for parking.

[0028] In this embodiment, the output end of the external condenser 9 is connected to the air intake duct in the cab 2, and the connecting pipeline between the fuel tank 15 and the heater 10 is equipped with an oil pump 16, which delivers a metered amount of oil from the fuel tank 15 to the heater 10 for combustion.

[0029] The working principle is as follows: In actual use, when the vehicle is parked, the refrigerant flows out from the evaporator 3 inside the vehicle through the expansion valve 4 and the low-pressure tee, and flows to the electric compressor 6 and the original vehicle compressor 7 respectively, depending on the actual situation. The electric compressor 6 starts (when the engine is stopped) or the original vehicle compressor 7 works (when the engine is running). The output ends of both send the refrigerant to the external condenser 9 for heat dissipation through the high-pressure tee 8. The cooled refrigerant returns to the evaporator 3 inside the vehicle to form a cycle, thus achieving cooling. The external condenser 9 is connected to the air intake duct of the driver's cab 2. When the engine is in cold or hot mode, the oil pump 16 in the fuel tank 15 delivers oil to the heater 10. At the same time, the battery or external power supply powers the heater 10. The heater 10 burns oil to heat the water in the water tank 11. The water pump 12 circulates the hot water. The exhaust fan 13 exchanges the heat generated by the hot water and sends it into the cab 2 for heating. The water after heat exchange is connected to the engine 14 to preheat the engine. The preheated water in the engine is then sent back to the water tank 11 by the water pump 12 for circulation. The air intake filter 17 of the heater 10 filters the air, and the exhaust fan 18 discharges the exhaust gas.

[0030] During use, the device and external equipment can be powered by the internal battery of the parking unit 1 or by an external 50kg portable power source with a 7.2 kWh power supply that is compatible with parallel air conditioning power. A quick-connect socket ensures a stable power supply, meeting the parking heating and cooling needs while reducing fuel consumption and vehicle wear.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
