Which gas is used in AC?
Which gas is used in AC?
The gas used is Freon, which is merely a marketed name for dichlorodifluoromethane (A CFC [chloro fluoro carbon]). This is a product that is being phased out because it adds to ozone depletion and thus the Global Warming effect.
What is the function of the air conditioner?
Air conditioning (often referred to as AC, A/C, or air con) is the process of removing heat and moisture from the interior of an occupied space to improve the comfort of occupants. Air conditioning can be used in both domestic and commercial environments.
What is the process of air conditioning?
Air-conditioning Process. It refers to the process of conditioning the interior air according to the human comfort. Vapor compression cycle is involved in domestic air conditioners. It has five major components; evaporator, condenser, compressor, expansion valve and double shaft motor.
Is air conditioning bad for your health?
Unless systems are cleaned regularly, air conditioners can be a source of health issues. Air contamination can become a severe problem that contributes to respiratory ailments in people. Additionally, air conditioning at work and home can lead to problems, such as colds, fevers, headaches and fatigue.
What is the basic principle of refrigeration?
The Refrigeration basic principle is that with the aid of a heat pump, the refrigerant is being compressed to the condenser and capillary tube thus increasing its temperature (50-60°C) and pressure (750 kPa) in the refrigerator being cooled down by the condensing unit to 32°C depending the existing ambient temperature.
What are the four stages of refrigeration?
The vapor-compression refrigeration cycle has four components: evaporator, compressor, condenser, and expansion (or throttle) valve. The most widely used refrigeration cycle is the vapor-compression refrigeration cycle.
Does AC fan bring in outside air?
In short, no. Though in split system air conditioners design, commonly heat pumps, part of your system is located outside your home, it does not take in outside air. Its main operational purpose of cooling the air in your home is not achieved by moving cool air inside, but by moving unwanted heat out.
What are the different types of air conditioning systems?
There are six different types of air conditioners that are each designed for a different space/reason. These six types of AC units are the basic central AC, ductless, window unit, portable unit, hybrid, and geothermal.
How does AC work diagram?
A central air conditioner cools with an outdoor compressor and condenser coil connected to an indoor furnace fitted with an evaporator coil. The refrigerant then passes through an expansion device that converts it to a low-pressure, low-temperature liquid, which returns to the indoor coil. And so the cycle goes.
How does temperature transfer in an HVAC system?
It works by transferring thermal energy from one medium to another through coils in the system. Heat exchangers use combustion gases to heat the air or a cold fluid to cool it. A heat exchanger in an HVAC system uses conduction to transfer heat.
What is the function of the air conditioner during summer?
So how does a typical air conditioning unit work and keep you sane during the heat of summer? The basic concept is that a chemical called a refrigerant loops from inside the home to outside and back again, absorbing and casting out heat in the process.
How do refrigerants work?
Refrigerant flows through the compressor, which raises the pressure of the refrigerant. Next the refrigerant flows through the condenser, where it condenses from vapor form to liquid form, giving off heat in the process. The refrigerant draws heat from the evaporator which causes the regrigerant to vaporize.
