 The air conditioning is not cooling one of the reasons: Freon is not enough (commonly known as snow is not enough) 
 Air conditioning is not cooling the second reason: the power supply voltage is not enough 
 The third reason of the air conditioning not cooling: air-conditioning power enough so that no refrigeration 
 Air conditioning not cooling, four reasons: the ambient temperature is too high lead to the air conditioning is not cooling 
 Air-conditioning refrigeration reasons: air conditioning for long periods of time cleaning and maintenance 
 The brass is too long between the air conditioning is not cooling Six reasons: the outdoor unit and indoor unit 
 Air conditioning a phenomenon this is only the wind rather than the cooling wind, generally what is the outdoor unit or air conditioning refrigeration systems. You first need to check the air conditioning outdoor unit is operating outside the machine is not running, then would be for air conditioning repair professionals to examine whether electrical or other compressor whether short or other problem. 

 If the outdoor unit is operating normally, may be necessary to see the air-conditioning refrigeration cycle system. The system for leaks, whether there is blockage, if you want to repair. View the various components of the air conditioning if there is blockage. Filter, condenser, gas pipelines, etc., congestion will cause the air conditioning cooling effect reduces. If the condenser of the outdoor unit or within the filter clogging caused by the cooling solution is very simple. Hand clean out blocked it. In fact, air-conditioning at regular intervals should be cleaned once in order to achieve good use of effects. 

 The condenser is also known as "liquefaction" is one of the major equipment, refrigeration equipment in the refrigeration process, which is the exothermic heat exchanger of the refrigerant in the system, the refrigerant from the compressor superheated steam into the condenser heat to the surrounding medium of water (or air), while its own release heat (latent heat) and condenses into liquid (ie, liquefaction). Cooler condenser, high pressure steam state into a high-pressure liquid state at about 1/3. Minor changes in this process of change in temperature, changes have to rely on the ambient temperature. 

 How do we determine the air conditioning is not cooling the problem. 
 Air conditioning is not cooling problem: the adequacy of the refrigerant to look at the air-conditioning mechanism, if there is no adequate refrigerant should be added, first the amount of current required to use the button-shaped current meter volume air conditioning, make it filling the refrigerant would not excessive, if the effect to see the control panel settings are correct. 
 The air conditioning is not cooling the two: to see the connection between the brass in the air conditioning outdoor and indoor unit is blocked phenomenon, if the unit to connect copper pipe and capillary is not blocked, then we should analyze the electromagnetic refrigerant control valve is blocked or stuck, or not fully work, we use the atomic table to test high-pressure, low pressure what kind of phenomenon. If the high-pressure high and low pressure is very low, or negative, then the electromagnetic refrigerant control valve is not fully open or completely stuck, first understand the role of the electromagnetic refrigerant control valve. 

 The air conditioning is not cooling problem: to check the electromagnetic refrigerant control valve coil resistance if it is saying the technical parameters. If consistent with the coil is good, the next should look at the PC board to the line indiscriminately output voltage value, the output voltage value and the technical parameters, the computer board is given refers to the life, electromagnetic refrigerant control valve operation of the mechanical part of the electromagnetic refrigerant control valve stuck or dirt blocking electromagnetic refrigerant control valve, then it must be replaced in order to achieve a cooling effect.
