HVAC Compressor is an important HVAC part for cooling in an air conditioning system.
Cooling is a process that allows an air conditioning system to transport heat from the inside of a building to the outside, thereby cooling the room temperature. A press reduces size, quantity and volume and increases the temperature of the airflow.
Step 1.
In an air conditioner, the refrigerant absorbs heat from the room’s evaporator coils, which convert it from a cold liquid into a low – or – warm refrigerant.
Step 2.
The compressor then converts the refrigerant into a hot, high-pressure gas, reduces its volume, pushes it down and turns it up again.
Step 3.
When the gas enters the condenser, the outside air flows through it, dissipating heat and producing a high – cool – liquid. When the gas evaporates, it dissolves again, generating heat, but also a higher liquid temperature.
How Do Hvac Compressors Work?
Piston compressors have most applications, but we can see how they work, but first, we want to study the design. Imagine a combustion engine if it were a reciprocating compressor that looks like this. Two of the six pistons are in each cylinder, the other two in the middle.
Step 1.
The pistons compress the refrigerant and the cylinders have two functions: they are used to hold low-pressure refrigerants and to deliver high-pressure refrigerants.
When the bottle is full of refrigerant gas, the suction line valve is closed, and the crankshaft begins to rotate, pulling at the piston and reducing the pressure in the cylinder. The difference in pressure between the cylinders and the suction pipes causes the valve to open and refrigerant to exit each cylinder at a lower pressure.
Step 2.
As the crankshaft continues its rotation, it pushes the pistons upwards and increases the pressure of the refrigerant gas, so that it has less space in the cylinder.
The valve presses the pressure of the cooling gas into the cylinder, which in turn presses against the pistons in the crankshaft.
Step 3.
Once the compressed refrigerant is in the cylinder, the process is repeated with the same amount of air, but in a different direction and again with other refrigerants.
Hvac Compressor: An Essential Component
The compressor plays a key role in cooling, on which the air conditioning system for cooling depends, as well as in heating the room.
When that time comes, it will probably be helpful to understand how the different types of compressors work. In fact, you will only get to know many of them after completing your training as an air conditioning system engineer and working in the field.
