Have you ever wondered how air conditioners work?
Environmental variables play a vital role when controlling the thermal conditions of the interior of a home. But so do the individual variables of each home, the objects and appliances that do not know contribute to a slight increase in home temperatures.
Our body’s thermal sensation is an important consideration, especially during the hot coldest and coldest seasons, when we need to provide a pleasant environment within our home.
Here come the air conditioners and their importance to ensure a fresh thermal sensation in the hottest months.
This appliance’s function is to control factors such as temperature, humidity, ventilation and, at the same time, without neglecting the preservation of the environment.
Understanding How air conditioning works
In a closed environment, four environmental factors are directly involved in thermal comfort: air temperature, humidity, air movement and air purity.
Cooling cycle operation
In the cooling cycle, a refrigerant is circulating whose task is to decrease or keep a room temperature below the temperature of the environment.
Thus, it is necessary to extract heat from the space that we want to refrigerate and transfer it to another body whose temperature is lower than goes through various states or conditions.
The name of each of these changes is called “processes”.
In this way, the refrigerant starts within an initial condition and then goes through a series of “processes” according to a defined sequence and then returns to its initial condition.
The whole of this series of processes is called the cooling cycle. The simple cooling cycle consists of four fundamental processes.
In this process, there is a refrigerant whose task is to decrease or keep a room temperature below the temperature of the environment. For this reason, the process is necessary, extract heat from the space that we want to refrigerate and transfer it to another body whose temperature is lower.
Cooling cycle processes
At first, the coolant is in a liquid state in the outdoor unit at high pressure. It is then sent to the indoor unit and, to achieve the cooling effect, is sent through an expansion element. We achieve two things: we reduce the pressure and temperature of the liquid and leave it with the necessary conditions for the operation.
In this part of the process, the liquid evaporates giving cold to the air of the premises to be air-conditioned (a fan drives it). Here, all the refrigerant inside goes through an evaporation process inside the evaporator and as a result, gas is obtained.
This gas returns to the outdoor unit to become a liquid state again. The gas is compressed here first. This process is carried out inside the compressor obtaining gas at high pressure.
High-pressure steam circulates through the condenser. Heat is evacuated to the outside, and the coolant is obtained in a liquid state.
