空调维修教程？英文双语对照

空调是现代生活中不可缺少的一部分，它提高了人们的生活水平，使人们在适宜的温度下生活。但是做为家用电器，长时间的使用，也难免会出现故障，那么出现故障该怎么办呢？本文就教教大家怎么处理。

空调基础知识

核心部件

空调器的制冷（制热）系统由压缩机、冷凝器、毛细管（或电子膨胀阀）、蒸发器四大部分组成。分体式空调器中，这4大部件分为室内机和室外机两部分。室外机有压缩机、冷凝器、毛细管（或电子膨胀阀）3大制冷（制热）部件，室内机只有1只蒸发器，它们之间用管路、截止阀来连接，从而成为一个完整的制冷（制热)系统。

压缩机

将气体压缩，将低压气体变成高压气体，常见的有涡旋式压缩机、转子式压缩机，为制冷剂提供从高温环境吸热、向高温环境放热的能量，帮助制冷剂循环顺利进行。

冷凝器

将制冷剂由气体冷凝变成液体，放出热量。

节流装置

将高压液体变成低温低压液体，常见的有毛细管和膨胀阀，制冷剂压力越低，沸点越低，节流装置的作用就是将制冷剂的压力降低到制冷剂对应的沸点比制冷时室内温度（需要从室内吸热），制热时的室外温度低（需要从室外吸热），保证制冷剂能从空气吸热，正常蒸发。

蒸发器

将制冷剂由液体蒸发变成气体，吸收热量。

循环原理：

制冷和制热原理

制冷

空调制冷时，制冷剂先经过压缩机变成高压气体；然后经过室外机换热器（冷凝器）冷凝放热变成高压液体；然后高压液体经过节流装置，会变成低温低压的液体；然后经过室内机换热器（蒸发器）蒸发吸热变成低温低压的气体，最后再回到压缩机。

制热

空调制热时，制冷剂先经过压缩机变成高压气体，然后会先经过室内机换热器（冷凝器）冷凝放热变成高压液体；然后高压液体经过节流装置，会变成低温低压的液体；然后经过室外机换热器（蒸发器）蒸发吸热变成低温低压的气体，最后再回到压缩机。

注意制冷制热时，制冷剂流向是不同的，制冷时先流过室外机换热器，此时室外机是冷凝器，室内机是蒸发器；制热时，制冷剂先流过室内机换热器，此时室内机是冷凝器，室外机是蒸发器。制冷制热不同状态时，空调会通过四通阀改变制冷剂的流向。上图红色方框内为四通阀。如果没有四通阀，空调只能实现单一制冷或者制热，不能冷热切换。

检修思路

空调检修遵循由室内到室外再到中间，先易后难。要想电路故障检修具体和简单化，就要在检修时把室内与室外电路、主电路与控制电路故障区别开来。

控制与主电路故障

1、对于压缩机频繁开停故障，可通过测量空调器负载电压与压缩机运行电流来判断故障部位。如压缩机运转电流过大，说明故障在主电路；如压缩机运转电流正常，说明故障在控制电路。

2、对于风机运转压缩机不启动故障，可通过观察室外交流接触器是否吸合来判定故障部位。如接触器吸合而压缩机不工作，说明故障在主电路；如接触器不吸合，说明故障在控制电路。对于变频空调压机不启动，可通过检测功率模块来排除故障。

3、测量室内与室外保护元件是否正常，来判断故障区域。如测量保护元件正常，说明故障在控制电路；如测量保护元件损坏，说明故障在主电路。

4、对于压缩机不运转故障，还可通过强行按动接触器，观察压缩机是否能正常制冷。如按下接触器后压缩机能运转且制冷，说明故障在控制电路；如按下接触器压缩机过流或不启动，说明故障在主电路。(变频压缩机不能采用此法)

5、对于压缩机频繁启动故障，如摸压缩机外壳温度过高，多为主电路或压缩机本身故障。

6、对于变频空调来说，可以通过空调器的故障指示灯来进行判断，如功率模块、通讯故障等。

室内与室外电路故障

1、有输入与输出信号线的空调器，可以使用短接方法来进行判断。如采用上述方法后空调器能恢复正常，说明故障在室外机；如故障没有消除，说明故障在室内机。

2、测量室外机接线端上有无交流或直流电压判断故障部位。如测量室外接线端子上有交流或直流电压，说明故障在室外机；如测量无交流或直流电压，说明故障在室内电路。

3、对功率较大的柜式空调器可通过观察室外接触器是否吸合，来判断故障部位。如接触器吸合，说明故障在室外机；如没有吸合，说明故障在室内机。

4、对于有故障显示的空调器可通过观察室内与室外故障代码来区分故障部位。

5、对于采用串行通讯的空调器电路，可用示波器测量信号线的波形来判断故障部位。

6、对于热泵型空调器不除霜或除霜频繁，则多为室外主控电路板故障。

7、有条件也可通过更换电路板来区分室外机故障。

空调故障检修方法

1、插上电源插头，室内机电源指示灯亮，如无电源指示，说明您家的电源有故障或指示灯损坏。（下图左起第一个为电源指示灯）

2、有电源指示，用遥控器按操作键，信号发射不出去。首先，检查遥控器内的电池是否有电，然后检查电池的正负极片触点有无氧化腐蚀，若上述正常，检查遥控器内部电路板是否损坏，可将遥控器靠近一台调幅收音机，按遥控器键进行干扰试验，听收音机是否发出有“嘟嘟”声，有声说明遥控器无故障。

3、当遥控器确定无故障时，信号还是发射不出去时，可用室内机强制运行开关验证，强制运行时，室内贯流风机和室外压缩机若运转正常，制冷效果良好，则证明空调器室内机红外接收部位有故障。

4、当你使用的遥控器装上新电池使用不到一个月就不显示时，可将遥控器的后盖打开，用95%的酒精清洗一下电路板和按键触点面导电胶片，干燥后，即可排除漏电故障，遥控器液晶显示缺字也可采用这种方法。

5、变频空调器中的温度传感器起着非常重要的作用，室内机有空气温度传感器和蒸发器温度传感器;室外机有空气温度传感器，高压管路传感器和低压管路传感器，有的传感器在长期使用后发生阻值变化，使控制特性改变，(如室内机空气温度传感器阻值变大后，会引起变频器输出频率偏低)，为了保证控制精度，及其相同的工作特性，确定传感器故障后，应换用原型号的产品。

6、在空调器出现故障时，如果鉴别整个控制系统是否有故障，可将室内机控制器上的开关放在“试运行”挡上，此时微处理器会向变频器发出一个频率为50Hz的信号。若此时空调器能运转，并保持频率不变工作，一般认为整个控制系统无大问题，可着重检查各传感器是否完好。如果空调器不能正常运行，说明控制系统有故障。

空调保养

1、经常清扫空调器面板和机壳的灰尘

一般使用干布擦拭。先擦拭，然后再用清水湿擦布擦除掉洗涤剂。切勿用40度以上热水、汽油、挥发性油及腐蚀性溶剂擦拭空调器面板和机壳。不应用硬毛刷刷洗空调器，以免损坏外壳，造成脱漆、褪色等。

2、定期清洗空调器的冷凝器和蒸发器盘管

可使用毛刷和吸尘器清洗盘管上的灰尘。注意在清洗时毛刷和吸尘器应沿盘管的垂直方向清扫，切勿沿水平方向清扫，以免碰坏盘管的肋片。

3、定期清洗空调器的空气过滤网

一般2至3周左右清扫一次。清扫时将过滤网抽出，用干的软毛刷刷去过滤网上的灰尘。也可用清水清洗去过滤网上的灰尘。晾干后再装入空调器使用。对灰尘较多的环境，过滤网的清洗应更经常，以免过滤网沾灰尘太多，影响空调器的通风量。

Air conditioning is the indispensable one part in modern life, it raised the living standard of people, make people lives below appropriate temperature. But as electric home appliances

Air conditioning ABC

Core component

Air conditioning implement refrigeration (make heat) system by compressor, condenser, capillary (or the electron expands a powerful person) , 4 much comprise evaporator. Fission type air conditioning implement in, component of this 4 large parts is mixed for indoor machine the machine outdoor two parts. The machine outdoor has compressor, condenser, capillary (or the electron expands a powerful person) 3 big refrigeration (make heat) component, indoor machine has an evaporator only, join comes with pipeline, shut-off valve between them, become a complete refrigeration thereby (make heat) system.

Compressor

Compress gas, will low-pressure gas turns high pressure into gas, have vortex type compressor, rotor type compressor commonly, offer for refrigeration agent from the absorption of heat of high temperature environment, energy that gives off heat to high temperature environment, help refrigeration agent goes on wheels circularly.

Condenser

Turn refrigeration agent into the liquid by aeriform condensation, emit quantity of heat.

Throttle unit

Turn high-pressured liquid into microtherm low-pressure liquid, common hairiness canaliculus and expand a powerful person, refrigeration agent pressure is lower, boiling point is lower, when the action of throttle unit will make the pressure of cryogen reduce the boiling point of refrigeration agent correspondence to compare refrigeration namely indoor temperature (need from indoor absorption of heat) , the outdoor temperature when making heat is low (need from the absorption of heat outdoor) , assure refrigeration agent can from air absorption of heat, evaporate normally.

Evaporator

Evaporate refrigeration agent by the liquid become gas, absorb quantity of heat.

Circular principle:

Refrigeration and the principle that make heat

Refrigeration

When air conditioning refrigeration, refrigeration agent turns high pressure into gas through compressor first; Pass heat exchanger of the machine outdoor next (condenser) condensation exothermic turns high pressure into the liquid; Next high-pressured liquid passes throttle unit, can turn microtherm into low-pressure liquid; Pass indoor machine heat exchanger next (evaporator) evaporate the gas that absorption of heat turns microtherm into low pressure, return compressor again finally.

Make heat

When empty modulation is hot, refrigeration agent turns high pressure into gas through compressor first, can pass indoor machine heat exchanger first next (condenser) condensation exothermic turns high pressure into the liquid; Next high-pressured liquid passes throttle unit, can turn microtherm into low-pressure liquid; Pass heat exchanger of the machine outdoor next (evaporator) evaporate the gas that absorption of heat turns microtherm into low pressure, return compressor again finally.

When noticing refrigeration makes heat, refrigeration agent flow direction is different, heat exchanger of the machine outdoor has flowed first when refrigeration, right now the machine outdoor is condenser, indoor machine is evaporator; When making heat, refrigeration agent has shed indoor machine heat exchanger first, right now indoor machine is condenser, the machine outdoor is evaporator. When refrigeration makes hot different state, air conditioning can change the flow direction of refrigeration agent through 4 a powerful person. Pursue gules on 4 a powerful person are inside pane. If do not have 4 a powerful person, air conditioning can realize onefold refrigeration to perhaps make heat only, cannot cold hot switch.

Overhaul train of thought

Air conditioning overhaul is abided by by indoor arrive outdoor arrive again among, first easy hind difficult. Want circuit corrective maintenance is specific with simplification, be about to be when the overhaul indoor with the circuit outdoor, main circuit and control breakdown distinguishs circuit to come.

Control and main circuit breakdown

1, leave often to compressor stop breakdown, can pass measure air conditioning implement moving electric current of laden voltage and compressor will judge breakdown place. Like compressor locomotive electric current passes big, demonstrative breakdown is in main circuit; If compressor movement electric current is normal, explain breakdown is dominating circuit.

2, do not start trouble to fan movement compressor, can close to decide through observing whether contactor of the communication outdoor is sucked breakdown place. If contactor is sucked,close and compressor does not work, demonstrative breakdown is in main circuit; If contactor is not sucked,close, explain breakdown is dominating circuit. Do not start to press of frequency conversion air conditioning, but through detecting power module removes trouble.

3, measure indoor as normal as element of the protection outdoor, will judge breakdown extent. It is normal to if measure,protect component, explain breakdown is dominating circuit; If survey protective element damage, demonstrative breakdown is in main circuit.

4, do not run to compressor breakdown, still can move contactor through be being pressed forcibly, observation compressor whether can normal refrigeration. If press the compressor after contactor can run and refrigeration, explain breakdown is dominating circuit; If press contactor compressor passes to flow or be not started, demonstrative breakdown is in main circuit. (Frequency conversion compressor cannot use this method)

5, start trouble often to compressor, if feel compressor crust temperature exorbitant, give priority to circuit or compressor itself breakdown more.

6, to frequency conversion air conditioning, can pass air conditioning implement breakdown indicator light will undertake judging, wait like breakdown of power module, communication.

Indoor with breakdown of the circuit outdoor

1, the air conditioning that has input and output line implement, can use short receive a method to undertake judging. If use the air conditioning after afore-mentioned methods implement can return to normal, demonstrative breakdown is outdoor machine; If breakdown was not eliminated, show trouble indoors machine.

2, measure the machine outdoor have on terminal judge breakdown place without communication or volts d.c. . If measure terminal of the wiring outdoor to go up,have communication or volts d.c. , demonstrative breakdown is outdoor machine; If measure,do not have communication or volts d.c. , show trouble indoors circuit.

3, bigger to power cabinet form air conditioning implement can close through observing whether the contactor outdoor is sucked, will judge breakdown place. If contactor is sucked,close, demonstrative breakdown is outdoor machine; If was not sucked,close, show trouble indoors machine.

4, the air conditioning that shows to having trouble implement can pass observation indoor will distinguish with code of the breakdown outdoor breakdown place.

5, the air conditioning of serial to using communication implement circuit, usable oscillograph measures the weaveform of line to judge breakdown place.

6, to heating up pump air conditioning implement not defrost or defrost are frequent, it is more outdoor advocate accuse circuit board breakdown.

7, also can pass conditionally change circuit board will distinguish trouble of the engine outdoor.

Method of air conditioning corrective maintenance

1, insert electrify source outlet, indicator light of indoor Electromechanical source is bright, if do not have power source directive, explain the power source of your home has trouble or indicator light damages. (Zun Qi laying a plan is power source indicator light the first times)

2, have power source directive, press operation key with the remote controller, signal blasts off not to go out. Above all, whether does the batteries inside inspection remote controller have report, examine cell next negative pole piece contact has corrode without oxidation, if afore-mentioned normal, inspection remote controller is in-house whether does circuit board damage, can stand by the remote controller radio of an amplitude modulation, by the remote controller key undertakes disturbing an experiment, listen to a radio to whether be given out have " toot toots " sound, phonic specification remote controller does not have breakdown.

3, when the remote controller does not have breakdown certainly, when signal still blasts off not to go out, usable and indoor aircraft moves switch test and verify compulsively, when moving compulsively, indoor be linked together flows it is normal that fan is like movement with the compressor outdoor, refrigeration result is favorable, prove air conditioning implement indoor machine is infra-red receive place to have trouble.

4, when the new cell of remote controller mount that uses when you does not use a month not to show, can open the rear cover of the remote controller, clean circuit board and film of electric conduction of key-press contact face with the alcohol of 95% , dry hind, can remove trouble of leakage of electricity, remote controller liquid crystal shows be short of a word to also can use this kind of method.

5, frequency conversion air conditioning implement the effect with the very main move since medium temperature sensor, indoor machine has air temperature sensor and; of evaporator temperature sensor the machine outdoor is available air temperature sensor, high-pressured pipeline sensor and low-pressure pipeline sensor, some sensor produce block to be worth change after be used for a long time, make control characteristic change, (After like indoor machine sky air temperature spends sensor block value to greaten, can cause transducer to output) of frequency on the low side, to assure to control precision, reach its identical job character, after affirmatory sensor breakdown, should trade the product that uses archetypal name.

6, in air conditioning implement when occurrence breakdown, if differentiate whole control system to whether have trouble, can put the switch on indoor machine controller in " try move " block on, right now microprocessor can give out a frequency to be the signal of 50Hz to transducer. The air conditioning when be like this implement can run, maintain frequency changeless job, think whole control system does not have big question commonly, manage to make do checks each sensor again in good condition. If air conditioning implement cannot move normally, the specification controls a system to have trouble.

Reason 2: Compressor pipeline photograph is touched

Eliminate: Cover on the pipe that the begin that adjusts tall, low-pressure canal appropriately with the hand perhaps touchs in easy photograph on rubber tube, lest be touched when give out unusual noise.

Upkeep costs

How much does family expenses air conditioning repair charge to want?

Actually the problem of charge, still want to look according to maintaining level, can divide for the most part for small long, in long, overhaul.

1, small degree is repaired
