The noise level from the HVAC system shall not exceed the values in the following table. How/Where to mount the Compressor. R-12 R-134a Refrigerants Problems with EV’s and A/C There are a few things to consider when trying to retain your A/C system. Particular care shall be required at the return air grilles, cab supply vents and galley ceiling air diffusers. a. DOE Vehicle Technologies Office . •It draws heat-laden gas from the evaporator at low temp/low pressure and compresses this gas, raising its temp/ Advanced Combustion Engine R&D Program . 2013 Annual Merit Review and Peer Evaluation Meeting. … Automotive Thermoelectric Generators and HVAC . Solid State Energy Conversion . Condenser – It is the device looks like a small radiator and is used after the compressor as it provides condensing i.e. 2. Remember, refrigerant in the air conditioning system can reach pressures of over 500 PSI – if one of those lines bursts while you’re working on the system, it can cause serious injury. Always wear the proper protective eyewear and clothing before working on any refrigeration system. The condenser is the component in which the heat absorbed in theevaporator is transferred to the atmosphere through thecondenser-cooling medium. Power supplies Many different supply voltages are used in the HVAC/R industry, ranging from 575-V, three-phase power supplies to 24-V control circuit voltages.Power supplies may be indicated by solid lines or by dashed Vehicle Technologies Office . Automotive technicians can be certified in one or more of the eight areas below. There are several significant changes in this revised edition. The only system control was a blower switch. Typically, water or air •The compressor is the workhorse of the system. 1 Automotive HVAC NVH quality: from design to vehicle integration Said NAJI 1 Sébastien GOUDE 1 Darius KURNIAWAN 2 1VALEO Thermal Systems, La Verrière, FRANCE 2VALEO Thermal Systems, Auburn Hills, USA Abstract Automotive Air Conditioning (A/C) system (Cold and hot loop + HVAC: Heating, Ventilation and Air Conditioning) is How to drive the compressor. Servicing Refrigerant Systems 1. As the refrigerant begins to boil, it can absorb large amounts of heat. The overall HVAC system shall be designed to minimize noise in the passenger and crew areas of the car. system. Refrigerant There are two types of refrigerants used in automotive applications. loads that make up the system. 2 Automotive Air-conditioning and Climate Control Systems In 1939 Packard marketed the first mechanical automotive A/C system which worked on a closed cycle. Chapter 4 has new values for climatic design information. Let’s take a look at some of the symbols used in electrical schematics. Automotive Heating and Air Conditioning, 8/e provides a complete, state-of-the-art source on automotive heating, ventilation, and air conditioning systems, as well as the practical skills that students must master to be successful in the industry. The compressor of the car air conditioning system is driven by the crankshaft of the engine through the belt drive. The system used a compressor, condenser, receiver drier and evaporator (fitted inside the boot/trunk) to operate the system. Air Conditioning Two general types of air conditioning (cooling) Refrigerant-based: refrigeration cycle moves heat from one space (indoors) to another (outdoors) Refrigerant evaporates and condenses continuously within cycle Refrigerant has a low boiling point, making it ideal for HVAC systems Similar to car AC system John Fairbanks . The material is divided into three major sections: general concepts, Chapters 1–10; air-conditioning systems, Chapters 11–16; and HVAC&R equipment, Chapters 17–20. • Brakes • Electrical/electrical systems • Engine performance • Suspension and steering • Automatic transmission and transaxle • Engine repair • Heating and air conditioning With EV ’ s take a look at some of the car condenser, receiver and...
