Have you ever wondered how air conditioners work?
Environmental variables play a very important role when trying to control the thermal conditions inside a home. But so do the individual variables of each home, objects and appliances that unknowingly contribute to a slight increase in home temperatures.
The thermal sensation of our body is an important consideration, especially during the hottest and coldest seasons, when we need to provide a pleasant environment within our home.
This is where air conditioners come in and their importance to guarantee a cool thermal sensation in the hottest months.
The function of this appliance is to control factors such as temperature, humidity, ventilation and, at the same time, without neglecting the preservation of the environment.
Four important variables to understand the operation of the air conditioner
In a closed environment, there are four environmental factors that directly intervene in thermal comfort: air temperature, humidity, air movement and air purity.
Refrigeration cycle operation
In the refrigeration cycle, a refrigerant circulates whose task is to lower or maintain the temperature of a room below the ambient temperature. best led light
For this, the process of extracting heat from the space that we want to cool is necessary and transferring it to another body whose temperature is lower that goes through different states or conditions.
The name of each of these changes is called “processes.”
In this way, the refrigerant starts within an initial condition, then goes through a series of “processes” according to a defined sequence and then returns to its initial condition.
The set of this series of processes is called “refrigeration cycle”. The simple refrigeration cycle is made up of four fundamental processes.
In this process, a refrigerant circulates whose task is to lower or maintain the temperature of a room below the temperature of the environment. It is for this reason that the process of extracting heat from the space that we want to cool is necessary and transferring it to another body whose temperature is lower.
Refrigeration cycle processes
Expansion:
At first, the refrigerant is in the liquid state in the outdoor unit under high pressure. It is then sent to the indoor unit and, to achieve the cooling effect, it is sent through an expansion element. With this we achieve two things: we reduce the pressure and temperature of the liquid and leave it with the necessary conditions for the operation.
Evaporation:
In this part of the process, the liquid evaporates, providing cold to the air in the room to be heated (it is driven by a fan). Here, all the refrigerant inside goes through an evaporation process inside the evaporator and as a result gas is obtained.
Compression:
This gas returns to the outdoor unit to become a liquid state again. Here the gas is compressed first. This process is carried out inside the compressor obtaining gas at high pressure.
Condensation:
High pressure steam circulates through the condenser. The heat is evacuated to the outside and the refrigerant is obtained in a liquid state.
