Air conditioning system for automobile

Abstract

The invention discloses an air conditioning system for an automobile. The air conditioning system comprises a compressor, a vapor and liquid separator, a third heat exchanger, a first air conditioning case, a second air conditioning case and throttling elements. When the air conditioning system is in a refrigerating mode, refrigerants flow out of a second heat exchanger and reach the third heat exchanger, heat is outwardly dissipated at the third heat exchanger, and then the refrigerants are divided into two branch flow channels; the refrigerants of the first branch flow channel flow to a first heat exchanger of the first air conditioning case to provide cold flows to a compartment; the refrigerants of the second branch flow channel flow to a battery heat exchanger of the second air conditioning case to provide cold flows to a battery. The air conditioning system for the automobile has the advantages that only the refrigerants circulate in the air conditioning system, heating and circulation of heating circulating working media are omitted, and accordingly the system is simple in manufacture.

Description

technical field [0001] The invention relates to the technical field of automobile air conditioning, in particular to an electric automobile air conditioning system or a hybrid electric automobile air conditioning system. Background technique [0002] With the development of low-carbon economy, more stringent requirements are put forward for energy saving and emission reduction. All countries in the world regard new energy vehicles as the strategic direction of the development of the automobile industry, and electric vehicles or hybrid vehicles are becoming the future due to their energy-saving and environmental protection characteristics. One of the aspects of automobile development. However, because electric vehicles use batteries as the power source and batteries as the core components, their cost and capacity / weight restrict the development of new energy vehicles; their air-conditioning systems are also different from the original automotive air-conditioning systems.

During these heat exchanges, there will definitely be heat loss, so the efficiency must be less than 1

In addition, when heating, because the specific heat of the working fluid in the cycle 2000 is relatively large, and the power of the electric heater is limited, the temperature rise of the working fluid in the cycle 2000 is relatively slow, and the temperature rise of the air is also slow, so To affect the comfort of passengers, and because the temperature of the battery is relatively low when it is first started, and the temperature rises slowly, it will affect the performance of the battery (such as shortened mileage and shortened service life); in addition, the system also There are refrigerant refrigeration cycle and heating cycle 2000 working medium heating cycle, the system has many parts and is relatively complicated, it is difficult to arrange on the vehicle, and the manufacturing cost is high
