Condenser Air Pre-Heating Stand for Development, Validation, and Continuous Improvement Testing of Climate Control Systems

摘要

In the operation of vehicular air-conditioning systems, the temperature of the condenser inlet air has significant effects on system performance and operating characteristics. In some vehicles, engine cooling module (ECM) inlet air is supplied from the engine compartment, subjecting the ECM to inlet air that is hotter than the ambient environment. In addition, vehicles in idle operation are subject to ECM air recirculation that can also elevate the ECM inlet air temperature. In order to conduct development, validation, and continuous improvement testing of Heating, Ventilating, and Air-Conditioning (HVAC) systems under conditions simulating "real-life," a condenser air pre-heating stand was built.
