Why air conditioning refrigeration are getting slower and slower? And the common solution

Sorching summer, no air conditioning is a kind of suffering, but air conditioning is used more long after, we will find that its cooling effect is becoming more and more slow, don't worry, today small make up for you a detailed introduction about the knowledge of the air conditioning, teach everyone how to change the air conditioning system. 。 。

sorching summer, no air conditioning is a kind of suffering, but air conditioning is used more long after, we will find that its cooling effect is becoming more and more slow, don't worry, today small make up for you a detailed introduction about the knowledge of the air conditioning, teach everyone how to change the air conditioning refrigeration effect! Air conditioning is the guarantee of we survived long hot weather couldn't stay for a long time under the air conditioner. But in the case of long-term use of air conditioning, air conditioning refrigeration effect does not meet the ideal requirements, why air conditioning refrigeration are getting slower and slower?

a, air conditioning and refrigeration principle is what?

1, the compressor will be gaseous freon compression for high temperature and high pressure liquid freon, and then sent to the condenser ( Seg) After heat dissipation become normal temperature high pressure liquid freon, so is blowing out hot air outdoor.

2, liquid freon via capillary, into the evaporator ( Indoor machine) , space suddenly increases, pressure decreases, and the liquid freon will vaporize, become a gas at low temperature of freon, to absorb a lot of heat, the evaporator will become cold, indoor machine of the fan will indoor air blows from the evaporator, so indoor machine out of the cold wind is blowing; Water vapor in the air is cooled after the evaporator will condense into water droplets, along the conduit flow, this is the reason why air conditioning will be out of the water.

3, then gas freon to go back to the compressor compression, continue to cycle. Heating has a call four-way valve components, freon in when the direction of flow of condenser and evaporator refrigeration instead, so the heating when the cold wind blowing, outdoor indoor machine blowing hot air. Actually is to use liquefied learned in junior middle school physics ( Changed from gas to liquid) To emit heat and boil ( Changed from liquid to gas) To the principle of heat absorption.

2, air conditioning and refrigeration slow reason have?

when indoor machine return air filter dirty air conditioning refrigeration mode, outlet air temperature is low, the indoor machine is indoor machine air volume is small, small total quantity of cold air conditioning in the room temperature speed down slowly. When the compressor start capacitance aging due to reasons such as high temperature, voltage fluctuation is frequent in capacity attenuation when the compressor can't normal, instant startup, only live on for a period of time in the voltage and current under the repeated impact is likely to start up; Beginning of this case air conditioning indoor machine out of the wind is not cold, only when the compressor start up outlet air temperature will reduce the indoor machine.

three, how to solve the problem of air conditioning refrigeration slow?

suggest to clean indoor machine return air filter and air moisture after back. Actually, cleaning air conditioning is not difficult, the material need for air conditioning disinfectant or special cleaner, and these two kinds of material inside will also be able to buy in the supermarket, the price is not expensive. In the cleaning process of concrete, combined with the style of the air conditioning is needed to take a different cleaning method, conventional, mainly including wall-mounted air-conditioner, and the two cabinet air conditioning cleaning method, difference was mainly for air conditioning has its own type.

1, wall-mounted air conditioning clean method:

( 1) Shut off the power, to ensure the safety of the cleaning processes;

( 2) Turn on the air conditioning panel, remove the air purification filters and filter;

( 3) See very dirty after heat sinks, took out the prepared cleaner to spray a few times, 2 ~ 3 cm distance control at best;

( 4) After spraying detergent, use cloth to wipe, had better use dry cloth, wipe after waiting for ten minutes;

( 5) Time passed, install the filter and filter to the original place, and then open state of refrigeration lasts for about 30 minutes, air conditioning in the process of operation, to internal water discharge, wall-mounted air-conditioner is clean.

2, cabinet air conditioning cleaning method

grille type air conditioning:

( 1) Turn off the power supply first;

( 2) Under the FengKouChu find dusty heat sink, wash detergent on the heat sink.

slide type air conditioning:

a slide in the process of cleaning air conditioning, the first thing to open air conditioning, then, turn the power off after see heat sink, then sprayed on the heat sink.

the two cabinet air conditioning after spraying cooling fin, need not use dry cloth to wipe the heat sink. Probably wait after a quarter of an hour, will open air conditioning refrigeration mode, about another 30 minutes, air conditioning internal sewage discharge automatically, has completed the cleaning work.
