Climatic wind tunnel (CWT) is a necessary test lab for the automotive research and development by simulating the environment (such as temperature, humidity, wind speed, sunshine, rain, snow and etc.) and vehicle running status (such as speed, resistance) under the open-road condition. It greatly reduces the cost and time of the automotive development.
The simulation range of CWT covers all kinds of climate from the equator to the poles. The chassis dynamometer simulates different road characteristics and vehicle operating status. There is no limit of location, season and time to do tests in the CWT, which helps to simulate natural conditions, extreme conditions and repeatability test under the same environmental conditions.
The CWT has a high requirement of the accuracy of temperature, humidity, insolation, wind speed and distributions around the automobile, so that the test results are very close to the actual situation. Normally, the CWT has two types of high and high & low temperature. The overall layout of the CWT is optional between vertical and horizontal.
The CWT is capable of the following tests: Engine/transmission cooling performance, cooling system components performance, HVAC comfort/control logic/optimization, drivability including cold start, cold drivability/snow/rain, heat damage and heat protection, component performance (brakes, etc.), equipment safety, emission, fuel economy, hybrid vehicle thermal performance, lubricant testing, etc..
This CWT is designed in accordance with the National Standards, Industry Standards and various Enterprise Standards for automotive A/C systems, ventilation systems, cooling systems and etc..
