The condenser houses several parts. This is where the expansion valve (also known as a metering device) comes in, normally a thermostatic expansion valve. As such, it draws its power from the engine. Get the VIP treatment you deserve with our exclusive maintenance plan. Car Air-Conditioner (Car A/C): Background. Signs of an ailing compressor include strange noises, fluid … Since heat naturally flows from a hotter to colder bodies, in order to dispense heat outdoors, the refrigerant must be hotter than the air outdoors. In case of no leaks, it’s a refrigerant issue we are looking at. This component, which also works with your furnace, circulates cooled air into your home and pulls room-temperature air back for re-cooling. As the refrigerant absorbs heat from the indoor air, it starts to evaporate to form a vapor. Understanding heat What is heat? Evaporator coils are very important to an air conditioner. Most people attempting to find details about air conditioner diagram of parts and certainly one of these is The copper tubes receive the depressurized, liquid refrigerant from the expansion valve. The function of the blower is to produce air movement to the space that is being conditioned. After passing through the compressor, it flows through the condenser coils. These systems use a refrigerant which, when changing state from a liquid to a gas, absorbs high quantities of heat from the air blown into the car and in turn cools and dehumidifies the car’s interior. Just like the condenser coils need the help of the condenser fan to facilitate heat transfer, the evaporator coils rely on the indoor air handler’s fan (aka the blower) to blow air over the coils. Whenever you turn on the car AC system, the compressor pumps gaseous or vaporized refrigerant to … ALL … It does this by squeezing the gas very tightly together. Always keep the car manual in a safe place so that you can refer to it whenever you have to maintain your car air conditioner. Air conditioner parts enable you to enjoy cool air on a hot summer day. Air conditioners don’t create cool air--they displace heat--but they’re about the nearest any man-made technology has come to what only nature can do. It then performs the same heat absorption process over and over again. If the A/C system requires substantial repairs, you may not have the equipment necessary to conduct those repairs at home. Theory Automotive Air Conditioning Training Manual 3. There are basically four types of fan that are commonly used in the HVAC equipment. Preparing for the Refrigerant . Car air conditioning is a system within your car that allows you to cool the interior air of the vehicle in hot weather, providing for a cooler environment for the occupants. This is due to the rapid expansion of the compressed gas. Will be to cool the atmosphere. Air conditioners use this mechanism to cool the air inside a house. We heat up the refrigerant in order to get its temperature higher than the outdoor temperature. An air conditioner transfers heat from the inside of a building, where it is not wanted, to the outside. Auto Air Conditioning Parts Supply. Again using the principles behind the combined gas law, which states that when pressure decreases so does its temperature, the expansion valve depressurizes the refrigerant and cools it down. In general, all car air-conditioners use the same ‘vapour compression refrigeration system’ with some small variations. It’s easy to take our refrigerators and air conditioners for granted. Common signs of an under-performing air conditioner are a lack of cool air and noisy operation. It receives the high pressure, high temperature refrigerant from the compressor. We use refrigerant because it changes states from liquid to vapor at convenient temperatures for the refrigeration cycle. There are some additional sensors, timers and valves, but the evaporator, compressor, condenser and expansion valve are the main components of an air conditioner.
