The cooling system in the air conditioner is created on the basis of the quality of liquids to receive heat during the transition to the gaseous fraction and give it away during condensation.
Cooling system in the air conditioner
- Compressor - it is necessary to increase the pressure of the refrigerant, move it along the cold path;
- Capacitor Is a radiator located in the outdoor unit. This is where the condensation of the refrigerant occurs or its transition to a liquid state;
- Evaporator - and this is the heatsink of the indoor module. Here the refrigerant is brought to boiling and evaporating temperatures;
- Thermostatic expansion valve (TRV) - located before the evaporator. Here the refrigerant pressure decreases. A copper coil is installed as a thermostatic valve in air conditioners;
- Air conditioner cooling fans - they provide movement of air mass around the condenser and evaporator. Needed to enhance heat transfer. The air in the room gives off heat to the refrigerant, while the outside air takes it in.
Copper tubes run between the condenser, the compressor and the thermostatic expansion valve, which forms the refrigeration circuit. Freon mixed with a drop of engine oil passes through the tubes.
Air conditioner cooling capacity
The cooling capacity of an air conditioner is the first indicator that buyers are interested in.
Will the air conditioner cope with the cooling of the room? Is all of its reserve being used, or will an overly strong compressor run half-heartedly?
For a rough calculation, the proportion is suitable:
- For 10 square meters of the serviced premises, 1 kilowatt of air conditioning cooling capacity is required.
That is, for a room of 20 square meters, a 2-kilowatt compressor is suitable. The cooling area of the air conditioner can be larger or smaller, depending on the location of the room (south or north), the number of windows, the number of equipment (in the office or shop), the number of people who are constantly in the room. But for residential premises, the air conditioning cooling area can be calculated using the above formula.
An accurate calculation is important, as a lack of capacity will increase the load on the compressor and the cooling fans of the air conditioner.
But the room temperature will not drop to the desired values. If you buy too powerful air conditioner "for growth", the entire compressor resource will not be used. Which entails pointless expenses.
