The invention discloses a system and method for regulating the temperature of an environmental wind tunnel test cabin. The system includes a main heat exchanger, a cooling pipeline and a heating pipeline, and the cooling pipeline and the heating pipeline are connected in parallel between the inlet and outlet of the main heat exchanger ; The cooling pipeline includes the first cooling branch, the second cooling branch and the third cooling branch arranged in parallel, which exchange heat with the exchangers circulating cooling water, frozen water and deep cooling water respectively; the first cooling branch The first on-off valve is set on the cooling line, the second on-off valve is set on the second cooling branch, and the third on-off valve is set on the third cooling branch; the first three-way regulating valve and the second three-way regulating valve are arranged in parallel on the cooling line. valve; the heating pipeline is provided with a third three-way regulating valve. The method of the present invention is applied to the system described above. The invention significantly improves the control accuracy level and response speed of the temperature regulation of the environmental wind tunnel test chamber, and the system and method of the application have a clear and simple logical structure, high reliability, and strong engineering implementability.
Description
technical field [0001] The present invention generally relates to the field of new energy vehicle environmental wind tunnel test chambers, and specifically relates to a system and method for regulating the temperature of an environmental wind tunnel test chamber. Background technique [0002] As consumers have higher and higher requirements for car functionality, comfort, and personalized experience, as well as the market demand for new energy Internet car companies to quickly update and iterate products, new energy car companies have gradually realized the self-owned car environment. The importance of the wind tunnel test chamber. The new energy vehicle wind tunnel environmental test chamber is used to simulate the real climate environment in nature, and is used to verify the matching development and performance of the vehicle, air conditioning system, battery module, and motor drive system. The temperature control range of the wind tunnel environmental test chamber require...
