Problems solved by technology

Traditional internal combustion engine vehicles can use the waste heat of the internal combustion engine and the heat of the engine exhaust to heat the cabin, while the power of electric vehicles mainly comes from the motor, which lacks the heat of the engine and can be used
In addition, in traditional automobiles, the blower and condensing motor are the main power sources for automotive air

Abstract

The invention discloses an air conditioning system of an automobile. The air conditioning system comprises a refrigerant circulating system and a coolant circulating system. The refrigerant circulating system can provide a cold source for the coolant circulating system and comprises a compressor, a vapor-liquid separator, an interior condenser, an exterior heat exchanger and an interior evaporator, the vapor-liquid separator is arranged in front of an air inlet of the compressor, and the interior condenser is connected with an outlet of the compressor; a second throttling element, a bypass flow path and an intermediate heat exchanger are arranged between the interior condenser and the exterior heat exchanger, and at least two throttling elements are respectively arranged in pipelines which run from the exterior heat exchanger to the interior evaporator and the intermediate heat exchanger respectively, so that refrigerants which are condensed by the exterior heat exchanger can be throttled by the throttling elements and then can flow to the interior evaporator and the intermediate heat exchanger when the refrigerant circulating system is in a refrigerating mode. The air conditioning system has the advantages that batteries can be cooled, heat can be absorbed from low-temperature heat sources in a heat pump manner and is used for heating, accordingly, the efficiency is improved, and power consumption is reduced.

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 features. 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. Traditiona...
