Problems solved by technology
Due to the problem of water circulation flow, there is a certain amount of waste of heat for engine cold start and auxiliary heating of the cab. The circulating water of an independent heat source will pass through the engine after flowing through the warm air core. When only auxiliary heating of the cab is required, it will The water in the entire circulating waterway of the engine is heated, resulting in energy waste

The invention provides a heating system used for an automobile and a control method thereof. The system comprises a warm wind chip, a heater, a switching unit, a first water pump, a second water pump, an engine and a controller, wherein the warm wind chip is provided with an input end and an output end; the output end of the heater is connected with the input end of the warm wind chip; the output end of the first water pump is connected with the input end of the heater via a first passage and the switching unit; the input end of the first water pump is connected with the output end of the warm wind chip; the output end of the second water pump is connected with the input end of the heater via a second passage and the switching unit; the input end of the second water pump is connected with the output end of the warm wind chip by the engine; the controller is connected with the switching unit and is used for controlling the switching unit to be switched between the first passage and the second passage to cause cooling liquid output by the output end of the heater to flow to the first water pump and the second water pump. The heating system used for the automobile has the functions of auxiliary heating, engine preheating and residual heat utilization and has the advantages of energy conservation and emission reduction.
Description
technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a heating system for automobiles and a control method thereof. Background technique [0002] The water heating independent heat source of traditional models is a single water pump system. Due to the problem of water circulation flow, there is a certain amount of waste of heat for engine cold start and auxiliary heating of the cab. The circulating water of an independent heat source will pass through the engine after flowing through the warm air core. When only auxiliary heating of the cab is required, it will The water in the entire circulating waterway of the engine is heated, resulting in energy waste. Contents of the invention [0003] The present invention aims at solving one of the above technical problems at least to a certain extent or at least providing a useful commercial choice. [0004] The first object of the present invention is to propose a heat...
