Embodiment Construction

[0017] Refer below figure 1 Explain the working process of energy-saving and efficient vehicle air-conditioning system.

[0018] The system has two working modes: heating and cooling:

[0019] 1. Working process of heating mode:

[0020] Switch the working mode of the four-way reversing valve 3 so that the first port 3-1 and the second port 3-2 of the four-way reversing valve 3 communicate; the third port 3-3 and the fourth port 3-4 communicate;

[0021] At this time, the first side of the condenser 4 is the hot side, and the second side is the cold side; the first side of the evaporator 9 is the cold side, and the second side is the hot side;

[0022] After the compressor 2 compresses the refrigerant 11 driven by the motor 1, the pressure and temperature of the refrigerant 11 increase, and then enters from the first port 3-1 of the four-way reversing valve 3, and then passes through the four-way reversing valve The second port 3-2 of 3 flows out of the four-way reversing valve 3 and ...

Abstract

The invention discloses a vehicular air conditioning system and a working method thereof, and belongs to the field of energy sources, power and the like. The system is characterized in that a vapor compression thermodynamic reverse cycle used for the system is used for adjusting the temperature of air in a compartment, and is further used for directly adjusting the temperature of seats. The system is particularly used for an electric vehicle without available waste heat, and under an extreme air temperature environmental condition, the temperature of air in the compartment is closer to the environment temperature only on the basis of seat temperature adjustment. The system is particularly suitable for air conditioning during vehicle running in severe cold winter and extremely hot summer. Compared with a conventional method for conditioning air only, the method is high in comfort, and the energy consumption can be adjusted according to the quantity of passengers, so that the system is more energy-saving and efficient.

Description

Technical field [0001] The invention relates to a vehicle air conditioning system and a working method thereof, and belongs to the field of energy and power. Background technique [0002] Vehicle air conditioning is the key to maintaining the comfort of the cabin. At present, the vehicle air conditioning mainly uses vapor compression thermodynamic reverse cycle to heat and cool the circulating air in the cabin. The air temperature in the cabin is adjusted by circulating air to adjust the comfort of the passengers in the cabin. The thermodynamic reverse cycle has a high COP (generally up to 3-5), so it has the most extensive application in vehicle air conditioning. [0003] However, the conventional vapor compression thermodynamic reverse cycle air-conditioning method is adopted. For the vehicle operating environment with low outdoor temperature, in order to meet the requirements of passenger comfort, the temperature in the cabin is generally higher due to the large air temperature ...
