What are the principles of air conditioner?
The basic principle of an air conditioner is a vapor compression cycle to minimize the air temperature with the help of a condenser, compressor, expansion valve, and evaporator. The complete cooling process is a heat transfer between the room air and refrigerant gas.
What is the basic principle of refrigeration?
The absorption of the amount of heat necessary for the change of state from a liquid to a vapor by evaporation, and the release of that amount of heat necessary for the change of state from a vapor back to the liquid by condensation are the main principles of the refrigeration process, or cycle.
What is principle of air conditioning and requirement of comfort air conditioning?
Principle. Water circulates in thin capillary tubes, the KARO Mats, or copper pipes, which are installed in the room ceiling. Those Mats create a cool or warm surface and so, condition the air using a natural principle: radiation (cooling emission about 80 W/m2, heating emission about 90 W/m2).
What is the difference between air conditioning and refrigeration?
Refrigeration keeps the cold air close, air conditioning pushes it away. Refrigeration uses coolant alone, air conditioning also uses the air from outside. Refrigeration deals with cooling and freezing, air conditioning deals with cooling and dehumidifying the air.
Why is the evaporator used?
Evaporators are commonly used to concentrate foods by using heat to evaporate water from the food. As the liquid is concentrated, its boiling point is elevated. Using low pressure, boiling of liquid foods (such as juices) is carried out at low temperatures and the heat labile food attributes are preserved.
What is the principle of air conditioning? - AskingLot.com
The working principle of the Air conditioner or AC is collecting hot air from a gives spaces and processing it to release cool air into the same space where the hot air had originally been collected. This process is done through the 5 steps such as the evaporator, compressor, condenser, expansion valve, Refrigerant.
What is the purpose of air conditioning?
Air conditioning refers to the technology of cooling inside places of rooms or buildings to reduce heat and make the environment more at ease. Air conditioning systems submit to the mechanics of how this machine works.
Why does an air conditioner cool a building?
In Air conditioner working, compon. Continue Reading. An air conditioner is able to cool a building because it removes heat from indoor air and transfers it outside. A chemical refrigerant in the system absorbs unwanted heat and pumps it through the piping system to the outer coil.
What is the most important part of a refrigerant system?
The compressor is the most important part of all three as it pumps the vapor refrigerant through the system. The capacitor temperature is very low and this converts gas with high gas content into low pressure liquid. Through a small hole, this fluid under pressure will flow into the evaporator.
How does an air conditioner compressor work?
Every air conditioner has a compressor inside it. It works to compress and pump the refrigerant gas. Compression of refrigerant produces heat. To dissipate this heat, compress ed refrigerant is pumped to the condenser coils where a fan blows the heat out to outer atmosphere.
What happens when a refrigerant is expanded?
Expansion valve releases the appropriate amount of refrigerant to evaporator (cooling coils) where liquefied refrigerant takes gaseous form. Conversion from liquid to gaseous state due to expansion produces chillness because energy is absorbed from the surrounding.
What happens when AC reaches set point?
With repetition of this cycle, room air will become cooler. When AC reaches to the set point, compressor stops working so temperature of refrigerant will increase over the time and when temperature of room will go beyond set point compressor will star working and compressing the refrigerant. I hope this is helpful.
How does an evaporator work?
In the process of exchanging liquids for gas, it extracts heat from the air around it. The evaporator has fins and will blow cold air into the room. Hot air is lighter than cold air, so it sits in the upper part of the room, whose heat is used to convert high pressure liquid into low pressure gas.
How does an air conditioner work?
An air conditioner is able to cool a building because it removes heat from the indoor air and transfers it outdoors. A chemical refrigerant in the system absorbs the unwanted heat and pumps it through a system of piping to the outside coil.
What is the air conditioning fan?
The fan, located in the outside unit, blows outside air over the hot coil, transferring heat from the refrigerant to the outdoor air. Most air conditioning systems have five mechanical components: • a compressor. • a condensor. • an evaporator coil. • blower.

What is a condenser coil?
The condenser coil is a series of piping with a fan that draws outside air across the coil. As the refrigerant passes through the condenser coil and the cooler outside air passes across the coil, the air absorbs heat from the refrigerant which causes the refrigerant to condense from a gas to a liquid state. The high-pressure, high-temperature ...
What is an evaporator coil?
The evaporator coil is a series of piping connected to a furnace or air handler that blows indoor air across it, causing the coil to absorb heat from the air. The cooled air is then delivered to the house through ducting.
What is the job of a compressor?
Its job is to draw in a low-pressure, low-temperature, refrigerant in a gaseous state and by compressing this gas, raise the pressure and temperature of the refrigerant. This high-pressure, high-temperature gas then flows to the condenser coil.
How does a window unit work?
The furnace blows air through an evaporator coil , which cools the air . Then this cool air is routed throughout your home by means of a series of air ducts. A window unit operates on the same principal , the only difference being that both the hot side and the cold side are located within the same housing unit.
How does an AC boost affect the system?
This boost has the impact that, for each system of power input into the system (state to power a light bulb in the shut system), the air conditioner gets rid of that power. To do so, the ac unit should raise its power consumption by the inverse of its “performance” (coefficient of performance) times the amount of power dissipated right into the system.
What is a PTAC system?
Packaged terminal a/c unit (PTAC) systems are also understood as wall-split a/c systems. They are ductless systems. PTACs, which are often made use of in hotels, have two separate devices (terminal bundles), the evaporative system on the interior and the condensing system on the outside, with an opening going through the wall and attaching them.
What is the Most Common Type of Air Conditioner?
There are many different types of air conditioners in the world. To better understand air conditioning theory, we need to focus on the most common type of air conditioner used around the world.
How Split Air Conditioners Work?
A split air conditioner has one indoor unit and one outdoor unit. The indoor unit delivers cold air while the outdoor unit produces hot air. Both units are connected by a set of insulated copper tubes and cables.
Why Refrigerants are Used for Air Conditioning?
In order to reduce the temperature in our room, physics said that we must remove heat energy from the room. This is governed by the first and second laws of thermodynamics.
How Refrigerants Work in Air Conditioning?
The refrigerant of every air conditioner has a design working temperature and pressure. This temperature and pressure are determined by the thermal comfort of the human body.
What is Refrigeration Cycle?
The refrigeration cycle starts with the compressor located inside the air conditioner outdoor unit. The compressor pressurizes the R32 refrigerant to about 363 psi which the temperature also rises to 42°C since Gas Law states that temperature is directly proportional to pressure.
What is Dehumidification in Air Conditioning?
Remember that we feel comfortable at 24°C and 55% relative humidity. In hot countries like Malaysia and Singapore, the average humidity can be around 80%. So, air conditioners need to bring that down to 55%.
Conclusion
The above is the theory and fundamentals of air conditioning. As you can see, air conditioning involves many principles and physics laws. Properties of refrigerants and thermal comfort are also included in air conditioning.
What Is an Air Conditioner?
Invented by Willis Carrier in 1902, the first modern air conditioner is a system that provides artificial air conditioning indoors. Air conditioners provide a comfortable living space by allowing indoor areas to cool or heat up, adjusting humidity levels in the environment, and filtering the particles and dust.
How Do Air Conditioners Work?
The operation of air conditioning is based on the second of the four fundamental laws of thermodynamics. According to this law, heat always flows from hot (high energy) to cold (low energy). The air conditioner’s primary function is to cool or heat up the indoor air. A special chemical liquid known as R22/R410 is used for this.
How Do Air Conditioners Cool Air?
When the air conditioners were first invented, they were not intended for heating purposes. In other words, the main principle of operation of air conditioner is completely based on the cooling cycle. The heating function was later developed based on the cooling process described below:
How Do Air Conditioners Heat?
The heating function of the air conditioners depends on whether they have a heat pump. Without a heat pump, air conditioners only provide cooling. The task of the heat pump is to change the direction of the refrigerant according to the purpose of the use of the air conditioner.
