汽车空调采暖系统故障检修学习手册1.5.1 采暖系统的功用采暖系统也称暖风系统，在汽车空调系统中，采暖是重要的功能之一。

汽车空调采暖系统的功用如下：1．冬季取暖在寒冷的冬季，汽车空调采暖系统可将车内空气或送入车内的外部新鲜空气加热，以提高车内空气温度。

2．调节车内温度与湿度现代汽车空调系统的空调器已采用冷暖一体化的形式，利用空调制冷系统和采暖系统，通过冷、热风的调和，可对车内的温度与湿度进行调节，以提高车内的舒适性。

3．车窗玻璃除霜在冬季或春季，由于车内、外温差较大，车窗玻璃会起雾和结霜，影响驾驶员的视线，不利于行车安全。

这时，可通过采暖系统吹出热风来除霜、除雾。

1.5.2 采暖系统的类型按热源不同，汽车空调采暖系统常见的可分为二种类型：余热式采暖系统与独立式采暖系统。

余热式采暖系统是利用发动机冷却水对车内空气进行加热的。

轿车的车内空间小，取暖需要的热量也少，所以一般都装用余热水暖式采暖系统。

该系统的优点是设备简单、使用安全、运行经济，缺点是热量小，且采暖受发动机工况的影响。

独立式采暖系统是利用独立的热源对车内空气或送入车内的外部新鲜空气加热。

独立热源通常是燃烧汽油、柴油或煤油等燃料的燃烧器。

独立式采暖系统也可分水暖和气暖两种。

大型客车常常采用独立式采暖系统。

独立式采暖装置的优点是采暖不受发动机工况影响，发动机不工作时也可对车内供热。

独立式采暖装置通常是利用空气或水作为传热介质，因此，其主要类型有空气加热采暖系统和水加热采暖系统。

1.5.3 余热水暖式采暖系统1．工作原理余热水暖式采暖系统工作原理如图1-98所示。

发动机冷却水温达到80℃时，冷却系中的节温器主阀门开启，使冷却水进行大循环。

节温器和加热器之间装有一个热水阀，需要采暖时，打开此热水阀。

从发动机水套出来的热水流经节温器主阀门后，一部分流到供暖系统的加热器，另一部分流到散热器散热。

进入加热器内的热水向加热器周围空气传热，在鼓风机作用下，车内或外部新鲜空气经过加热器后，冷空气变成了热空气，热空气经通风管道的不同出风口被送入车内。

汽车空调系统维护及故障解决技巧汽车空调系统是我们日常生活中非常重要的一部分，它能够为驾驶者和乘客提供舒适的驾乘环境。

然而，如果不及时进行维护和解决故障，汽车空调系统可能出现问题，影响驾驶者和乘客的体验。

本文将详细介绍汽车空调系统的维护和故障解决技巧，以帮助读者更好地了解和处理相关问题。

一、汽车空调系统维护技巧1. 定期更换空调滤清器：空调滤清器的作用是过滤空气中的污染物，防止灰尘和细菌进入车内。

定期更换空调滤清器可以保持空气流通畅，避免异味的产生，一般情况下建议每年更换一次。

2. 清洁空调系统：使用专用的清洁剂清洁汽车空调系统可以去除积尘和异味，保持系统的正常运作。

首先需要找到汽车空调系统的进气口，将清洁剂喷洒到进气口，然后启动车辆，打开空调系统，让清洁剂进入系统内部进行清洁。

清洁完成后，关闭空调系统，继续运行车辆，将清洁剂排出系统。

3. 检查制冷剂压力：制冷剂是汽车空调系统的重要组成部分，定期检查制冷剂的压力可以保证系统的正常运行。

使用专用的制冷剂压力表，在正常工作温度下检查制冷剂的压力是否在正常范围内，如有异常应及时添加或排放制冷剂。

4. 注意保养汽车电池：汽车电池的正常工作对空调系统的正常运行至关重要。

定期检查电池的电量和电解液的水平，确保电池的正常工作。

此外，在更换电池时要注意连接正确的极性，避免损坏空调系统电路。

二、汽车空调系统故障解决技巧1. 空调制冷效果差：如果汽车空调制冷效果变差，可能是由于制冷剂不足导致的。

检查制冷剂压力是否正常，如不正常则需要添加制冷剂。

如果制冷剂压力正常，但制冷效果依然差，可能是由于空调系统的其他部件出现故障，建议前往维修站点进行详细检查和维修。

2. 空调系统漏水：如果发现汽车空调系统有漏水现象，可能是由于密封件老化或损坏导致的。

首先检查空调系统的排水管是否堵塞，如果未发现堵塞现象，可能是密封件需要更换。

如果不了解汽车维修，建议寻求专业人员的帮助。

3. 空调系统异味：如果汽车空调系统散发出异味，可能是由于滤清器或蒸发器上的细菌和霉菌滋生导致的。

汽车空调系统维修手册汽车空调系统的维修空调系统主要部件包括压缩机、平行流冷凝器、双蒸（前蒸和顶蒸）、系统管路及控制电路等。

该系统采用对环保无害的R134a作为制冷剂。

为保证该空调系统的正常使用和制冷效果达到要求，须及时对空调系统进行维护、预防和排除各种可能或已经出现的问题。

一.检修工具及其使用方法1.岐管压力计岐管压力计是测定系统压力的重要工具，一般采用两表头的结构形式，其中一块表用在系统低压侧，另一块表用在系统高压侧。

表和系统的连接是通过岐管和压力软管，岐管上有两个表头接口和三个软管接口，岐管的两端有手轮，用来控制制冷剂流量。

在低压表下接低压软管，在高压表下接高压软管，中间接口是用来进行抽真空、充制冷剂或其它维修之用。

低压端和高压端分别装有手动截流阀，顺时针把阀拧到头，则岐管截流，表上的读数指出该孔的压力值。

当两个手阀都置在关断的位置，这时，软管与对应的表头还是相通的，可读出高、低压的数值。

如逆时针转动手轮，则阀被打开，系统就与岐管的中间孔相连通。

这时，只是在容许制冷剂充入或排出系统才这样做。

假使低压截流阀打开只有低压与中间孔相通，低压表仍然可指示低压侧状态。

高压侧的截流阀关闭着，高压表还是显示高压状态。

如果高压侧的截流阀打开，而低压侧仍关断，结果也是类似的。

如果两个截流阀都打开，则都与中间孔相通，那么表上读数就不反映真实的情况了，这种情况一般是对系统抽真空用。

压力软管可承受7.5Mpa的工作压力，其破坏压力超过14MPa。

高、低压软管和中间孔连接的软管颜色各不相同，高压软管为红色、低压软管为蓝色、中间软管为绿色，避免连接错误导致损坏表头。

岐管压力计有R134a和R12两种类型，二者不能混用，以免影响汽车空调系统正常工作和制冷效果及损坏岐管压力计。

2.检漏仪检漏是一项非常重要又频繁的基本操作技能。

在汽车空调系统中的检漏方法有肥皂水、卤素检漏灯和电子检漏仪等。

肥皂水检漏是最经济、最简单，也是最有效的方法。

汽车空调系统维修入门教程随着汽车的普及，汽车空调系统的维修需求也越来越大。

对于一些爱车人士来说，学习汽车空调系统的维修知识是非常有必要的。

本文将为大家介绍汽车空调系统维修的入门知识，帮助大家解决一些常见的问题。

一、了解汽车空调系统的基本原理在学习汽车空调系统维修之前，我们首先需要了解汽车空调系统的基本原理。

汽车空调系统主要由压缩机、冷凝器、蒸发器和膨胀阀等组成。

空调系统通过压缩机将制冷剂压缩成高温高压气体，然后通过冷凝器将制冷剂散热，变成高温高压液体。

接下来，制冷剂通过膨胀阀进入蒸发器，在蒸发器内部与空气接触，吸收热量，变成低温低压气体。

最后，低温低压气体再次进入压缩机循环，实现空调系统的制冷效果。

二、常见故障及解决方法1. 空调制冷效果差当汽车空调制冷效果差时，可能是由于制冷剂不足或者制冷系统存在泄漏导致的。

首先，我们可以检查制冷系统的压力，如果压力过低，可以通过添加适量的制冷剂来提高压力。

如果压力正常，但制冷效果依然差，那么可能存在制冷系统的泄漏问题。

这时，需要使用专业的检漏仪来检测泄漏点，并进行修复。

2. 空调制冷效果突然变差如果汽车空调的制冷效果突然变差，可能是由于空调系统的堵塞导致的。

在这种情况下，我们可以尝试清洗空调系统的冷凝器和蒸发器，以去除堵塞物。

如果清洗后仍然没有改善，那么可能需要更换冷凝器或蒸发器。

3. 空调制冷时有异常噪音当汽车空调在制冷过程中发出异常噪音时，可能是由于压缩机或风扇的故障引起的。

我们可以先检查压缩机和风扇是否有异物或杂质，需要清理干净。

如果清理后仍然有噪音，那么可能需要更换压缩机或风扇。

4. 空调制冷时有异味当汽车空调在制冷过程中有异味时，可能是由于空调系统内部的细菌或霉菌滋生导致的。

这时，我们可以使用专业的空调清洗剂进行清洗，以去除异味。

三、维修工具及注意事项在进行汽车空调系统的维修时，我们需要准备一些基本的维修工具，如扳手、螺丝刀、压力表和检漏仪等。

此外，还需要注意以下事项：1. 安全第一：在进行汽车空调系统的维修时，一定要确保车辆处于停车状态，并切断电源。

Air ConditioningYour car's air conditioning is asealed system. Any major mainte-nance, such as recharging, shouldbe done by a qualified technician.There are a couple of things youcan do to make sure the air condi-tioning works efficiently.Periodically check the engine'sradiator and air conditioningcondenser for leaves, insects, anddirt stuck to the front surface.These block the air flow andreduce cooling efficiency. Use alight spray from a hose or a softbrush to remove them.The condenser and radiator finsbend easily. Only use a low-pressure spray or soft-bristle brushto clean them.AIR CONDITIONINGCONDENSERRun the air conditioning at leastonce a week during the coldweather months. Run it for at leastten minutes while you are drivingat a steady speed with the engine atnormal operating temperature.This circulates the lubricating oilcontained in the refrigerant.If the air conditioning does not getas cold as before, it is probablybecause some of the refrigerant hasleaked from the system. Have yourdealer check the system for leaksand recharge the system withRefrigerant CFC-12 (R-12). (SeeSpecifications on page 208 .)Whenever you have the air condi-tioning system serviced, make surethe service facility uses a refrige-rant recycling system. This systemcaptures the refrigerant for reuse.Releasing refrigerant into the at-mosphere can damage the environ-ment.MaintenanceNOTICENOTICEEngine BeltsCOMPRESSOR BELTCheck the condition of the two engine belts. Examine the edges of each belt for cracks or fraying.Check the tension of each belt by pushing on it with your thumb midway between the pulleys.The belts should have the following "play" or deflection.Alternator belt:7.5-9.5 mm (0.30-0.37 in)Compressor belt:6 — 9 mm (0.2 — 0.4 in)If you see signs of wear or loose-ness, have your dealer adjust or replace the belts.TiresTo safely operate your car, your tires must be the proper type and size, in good condition with adequate tread, and correctlyinflated. The following pages give more detailed information on how and when to check air pressure,how to inspect your tires fordamage, and what to do when your tires need to be replaced.MaintenanceALTERNATOR BELTTiresInflationKeeping the tires properly inflated provides the best combination of handling, tread life and riding comfort. Underinflated tires wear unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated.Overinflated tires can make your car ride more harshly, are moreprone to damage from road hazards,and wear unevenly.We recommend that you visually check your tires every day and use a gauge to measure the air pressure at least once a month. If you think a tire might be low, check itimmediately. Remember to check the spare tire at the same time you check all the other tires.Check the pressure in the tireswhen they are cold. This means the car has been parked for at least three hours. If you have to drive the car before checking the tire pressure, the tires can still beconsidered "cold" if you drive less than 1.6 km (1 mile).If you check the pressure when the tires are hot (the car has been driven several miles), you will see readings 28 to 41 kPa (0.3 to 0.4kg/cm 2,4 to 6 psi) higher than the cold reading. This is normal. Do not let air out to match the specified cold pressure. The tire will be underinflated.Recommended Tire Pressures for Normal DrivingThe following chart shows the recommended cold tire pressures for most normal driving conditions and speeds. Tire pressures for high speed driving are shown on page 213.The compact spare tire pressure is:415 kPa (4.15 kg/cm2 , 60 psi)The pressures are also given on the tire information label on the front passenger's door jamb.MaintenanceTiresYou should get your own tire pressure gauge and use it when-ever you check your tire pressures.This will make it easier for you to tell if a pressure loss is due to a tire problem and not due to a variation between gauges.Tubeless tires have some ability to self-seal if they are punctured.However, because leakage is often very slow, you should look closely for punctures if a tire starts losing pressure.InspectionEvery time you check inflation, you should also examine the tires for damage, foreign objects, and wear.You should look for:Bumps or bulges in the tread or side of the tire. Replace the tire if you find either of these condi-tions.Cuts, splits, or cracks in the side of the tire. Replace the tire if you can see fabric or tread.Excessive tread wear.INDICATOR LOCATION MARKSTREAD WEAR INDICATORSYour car's tires have wear indica-tors molded into the tread. When the tread wears down to that point,you will see a 12.7 mm (1/2 inch)wide band running across the tread.This shows there is less than 1.6mm (1/16 inch) of tread left on the tire. A tire that is this worn gives very little traction on wet roads.You should replace the tire if you can see the tread wear indicator in three or more places around the tire.MaintenanceIn addition to proper inflation,correct wheel alignment helps to decrease tire wear. You should get your car's wheel alignment check-ed every 12 months or 24,000 km (15,000 miles).CONTINUEDMaintenanceTiresThe tires were properly balanced by the factory. They may need to be rebalanced at some time before they are worn out. Have yourdealer check the tires if you feel a consistent vibration while driving.A tire should always be rebalanced if it is removed from the wheel for repair.Make sure the installer balances the wheels when you have newtires installed. This increases riding comfort and tire life. Your car's original tires were dynamic or"spin" balanced at the factory. For best results, have the installer perform a dynamic balance.Improper wheel weights can damage your car's aluminum wheels. Use only genuine Acura wheel weights for balancing.Tire RotationTo help increase tire life and distribute wear more evenly, you should have the tires rotated every 12,000 km (7,500 miles). Move the tires to the positions shown in the chart each time they are rotated.Replacing Tires and Wheels The tires that came with your car were selected to match the perform-ance capabilities of the car while providing the best combination ofhandling, ride comfort, and long life.You should replace them with radial tires of the same size, load range, speed rating, and maximum cold tire pressure rating (as shown on the tire's sidewall). Mixingradial and bias-ply tires on your car can reduce its braking ability,traction, and steering accuracy.MaintenanceFrontNOTICETiresIt is best to replace all four tires at the same time. If that is not possi-ble or necessary, then replace the two front tires or the two rear tires as a pair. Replacing just one tire can seriously affect your car's han-dling.If you ever need to replace a wheel,make sure the wheel's specifi-cations match those of the original wheel that came on your car. Re-placement wheels are available at your Acura dealer.Wheels and Tires Wheels:15x6JJ Tires:205/60R15 91HSee Tire Information on page 212 for additional information about tire and wheel size designations. See page 213 for information about DOT Tire Quality Grading.Winter DrivingTires that are marked "M +S" or "All Season" on the sidewall have an all-weather tread design. They should be suitable for most winter driving conditions. Tires without these markings are designed for optimum traction in dry conditions.They may not provide adequate performance in winter driving.For the best performance in snowy or icy conditions, you should install snow tires or tire chains. They may be required by local laws under certain conditions.CONTINUEDMaintenanceTiresSnow TiresIf you mount snow tires on your Acura, make sure they are radial tires of the same size and load range as the original tires. Mount snow tires on all four wheels to balance your car's handling in all weather conditions. Keep in mind the traction provided by snow tires on dry roads may not be as high as your car's original-equipment tires.You should drive cautiously even when the roads are clear. Check with the tire dealer for maximum speed recommendations.Tire ChainsMount snow chains on your car when warranted by driving condi-tions or required by local laws.Make sure the chains are the cor-rect size for your tires. Install them only on the front tires. If metal chains are used, they must be SAE class"S". Cable type traction de-vices can also be used.When installing chains, follow the manufacturer's instructions and mount them as tightly as you can.Drive slowly with chains installed.If you hear the chains contacting the body or chassis, stop and tighten them. If they still make contact, slow down until it stops.Remove the chains as soon as you begin driving on cleared roads.Chains of the wrong size or that are improperly installed can damage your car's brake lines, suspension,body, and wheels. Stop driving if you hear the chains hitting any part of the car.MaintenanceNOTICE。

tires wear unevenly,adversely affect handling and fuel economy,and are more likely to fail from being overheated.Overinflated tires can make your car ride more harshly,are more prone to damage from road hazards,and wear unevenly.To safely operate your car,your tires must be the proper type and size,in good condition with adequate tread,and correctly inflated.The following pages give more detailed information on how and when to check airpressure,how to inspect your tires for damage and wear,and what to do when your tires need to be replaced.We recommend that you visually check your tires every day.If you think a tire might be low,check it immediately with a tire gauge.InflationTires189Use a gauge to measure the airpressure at least once a month.Even tires that are in good condition may lose one to twopsi (10to 20kPa,0.1to 0.2kgf/cm )per month.Remember to check the spare tire atthe same time you check all the other tires.Check the pressurein the tires when they arecold.This means the car has been parked forat least three hours.If you have to drive the car before checking the tire pressure,the tires can still be considered ‘‘cold’’if you drive less than 1mile (1.6km).These pressures are also given on the tire information label on the driver’s doorjamb.The compact spare tire pressure is:Tires19060psi (420kPa ,4.2kgf/cm )Tubeless tires have some ability to self-seal if they are punctured.However,because leakage is often very slow,you should look closely for punctures if a tire starts losing pressure.Your car’s tires have wear indicators molded into the tread.When the tread wears down to that point,you will see a 1/2inch (12.7mm)wide band running across the tread.This shows there is less than 1/16inch (1.6mm)of tread left on the tire.A tire that is this worn gives very little traction on wet roads.You should replace the tire if you can see the tread wear indicator in three or more places around the tire.Tires191In addition to proper inflation,correct wheel alignment helps to decrease tire wear.If you find a tire is worn unevenly,have your dealer check the wheel alignment.The tires were properly balanced by the factory.They may need to be rebalanced at some time before they are worn out.Have your dealer check the tires if you feel a consis-tent vibration while driving.A tire should always be rebalanced if it is removed from the wheel for repair.You should not rotate your Honda’s tires.The front and rear tires are different sizes,so they cannot be rotated front-to-rear.The original-equipment tires on your Honda have a unidirectional tread pattern,so they cannot be rotated side-to-side.The tires that came on your car were designed and constructed to provide superior grip during acceleration,braking,and cornering.As a trade-off,they will wear more rapidly than tires used on ordinary passenger cars.Because of the car’s weight distribution,and the fact that they are the driving wheels,you may expect the rear tires to wear more rapidly than the front tires.MaintenanceTire RotationTire WearTires192CONTINUEDThe tires that came with your car were selected to match the perform-ance capabilities of the car while

Air Conditioning SystemYour car's air conditioning is a sealed system. Any majormaintenance, such as recharging,should be done by a qualified technician. There are a couple of things you can do to make sure the air conditioning works efficiently.Periodically check the engine's radiator and air conditioningcondenser for leaves, insects, anddirt stuck to the front surface.These block the air flow and reduce cooling efficiency. Use a light spray from a hose or a soft brush to remove them.The condenser and radiator fins bend easily. Only use a low-pressure spray or soft-bristle brush to clean them.Run the air conditioning at least once a week during the cold weather months. Run it for at least 10 minutes while you are driving at a steady speed with the engine at normal operatingtemperature. This circulates the lubricating oil contained in the refrigerant.If the air conditioning does not get as cold as before, have your dealer check the system.Recharge the system withRefrigerant HFC-134a (R-134a).See Specifications on page 199.Whenever you have the air conditioning system serviced,make sure the service facility uses a refrigerant recyclingsystem. This system captures the refrigerant for reuse. Releasing refrigerant into the atmosphere can damage the environment.MaintenanceAIRCONDITIONING CONDENSERNOTICENOTICEEngine Belts, TiresEngine BeltsCheck the condition of the two engine belts. Examine the edges of each belt for cracks or fraying.Check the tension of each belt by pushing on it with your thumb midway between the pulleys.The belts should have the following "play" or deflection.Alternator belt:(on cars without A/C)0.41—0.49 in. (10.5—12.5 mm)(on cars with A/C)0.31—0.41 in. (8.0—10.5 mm)Power steering belt:0.51—0.63 in.

Remember to check the spare tire at thesame time you check all the other tires.Check the pressure in the tires when they are cold. This means the car has been parked for at least three hours. If you have to drive the car before checking the tire pressure, the tires can still be considered "cold" if you drive less than one mile (1.6 km).If you check the pressure when the tires are hot (the car has been driven several miles), you will see readings four to six PSI higher than the cold reading. This is normal. Do not let air out to match the specified cold pressure. The tire will be underinflated.Recommended Tire Pressures for Normal DrivingThe following chart shows the recommended cold tire pressures for most normal driving conditions and speeds. Tirepressures for high speed driving are shown on page 203.These pressures are also given on the tire information label on the driver's doorjamb.You should get your own tire pressure gauge and use itwhenever you check your tire pressures. This will make it easier for you to tell if a pressure loss is due to a tire problem and not due to a variation between gauges.MaintenanceTIRE INFORMATION LABELTiresTubeless tires have some ability to self-seal if they are punctured.However, because leakage is often very slow, you should look closely for punctures if a tire starts losing pressure.InspectionEvery time you check inflation,you should also examine the tires for damage, foreign objects, and wear.You should look for:Bumps or bulges in the tread or side of the tire. Replace the tire if you find either of these conditions.Cuts, splits, or cracks in the side of the tire. Replace the tire if you can see fabric or cord.Excessive tread wear.Your car's tires have wearindicators molded into the tread.When the tread wears down to that point, you will see a 1/2 inch (12.7 mm) wide band running across the tread.
