An air conditioner cools a room, a whole house, or an entire business premise. Air conditioners use chemicals that easily convert from a gas to a liquid and back again. This chemical is used to transfer heat from the air inside of a home to the outside air. The machine has three main parts. They are a compressor, a condenser and an evaporator. The compressor and condenser are usually located on the outside air portion of the air conditioner. The evaporator is located on the inside the house, sometimes as part of a furnace. That's the part that heats your house.
The working fluid arrives at the compressor as a cool, low-pressure gas. The compressor squeezes the fluid. This packs the molecule of the fluid closer together. The closer the molecules are together, the high its energy and its temperature. The working fluid leaves the compressor as a hot, high pressure gas and flows into the condenser. If you looked at the air conditioner part outside a house, look for the part that has metal fins all around. The fins act just like a radiator in a car and helps the heat go away, or dissipate, more quickly. When the working fluid leaves the condenser, its temperature is much cooler and it has changed from a gas to a liquid under high pressure. The liquid goes into the evaporator through a very tiny, narrow hole. On the other side, the liquid's pressure drops. When it does it begins to evaporate into a gas. As the liquid changes to gas and evaporates, it extracts heat from the air around it. The heat in the air is needed to separate the molecules of the fluid from a liquid to a gas. The evaporator also has metal fins to help in exchange the thermal energy with the surrounding air.
By the time the working fluid leaves the evaporator, it is a cool, low pressure gas. It then returns to the compressor to begin its trip all over again. Connected to the evaporator is a fan that circulates the air inside the house to blow across the evaporator fins. Hot air is lighter than cold air, so the hot air in the room rises to the top of a room. There is a vent there where air is sucked into the air conditioner and goes down ducts. The hot air is used to cool the gas in the evaporator. As the heat is removed from the air, the air is cooled. It is then blown into the house through other ducts usually at the floor level. This continues over and over and over until the room reaches the temperature you want the room cooled to. The thermostat senses that the temperature has reached the right setting and turns off the air conditioner. As the room warms up, the thermostat turns the air conditioner back on until the room reaches the temperature.
One of the most common causes of failure is that some one has switched off the power supply. So check that fuses circuit breakers and isolators are all OK and working.
Another common cause is blocked air filters, so check they are clean and are regularly kept clean. It helps to refer to the manufacturers operating instructions as well.
Also check the remote for mode (cooling, dry or fan), temperature, fan speed etc. If all else fails and you are still having a problem, contact our service department.
Air conditioning and building services systems require regular maintenance to ensure safety and optimum operational efficiency. Warranties are only applicable if the system or equipment is regularly maintained by an approved organisation.
To simply explain, relate this to a car which like air conditioning has many rotating and wearing parts, your warranty will not be honoured if you don't have regular servicing (maintenance)
No more than you do or any ventilation system does for airborne viruses and bacteria. Many people are susceptible to dryness sometimes caused when an air conditioning system is badly designed or maintained and the relative humidity is reduced too much. It's a fact that basically coughs and sneezes spread diseases.
Air conditioning covers many things but is mainly, heating, cooling, ventilation, fresh air, filtration and control of humidity. Comfort cooling mainly relates to provision of just cooling to improve comfort.
Close control air conditioning is really as the name implies, both temperature, humidity and air cleanliness are closely controlled and often to fine tolerances if necessary.
An electrical inverter is used to vary the frequency of the power supply from a normal 50Hz enabling fine step speed control of motors (compressors) this in turn varies the quantity of refrigerant delivered and hence variable cooling or heating capacity.
Coefficient of Performance, which is the ratio between the power input and power output. For example a modern heat pump will provide 3kw of heat for 1kw of electrical power input. Therefore the COP is expressed as 3 - 1.
Energy efficiency ratio is used to express the relative efficiency of a heating or cooling device by dividing the heat output by the power input. The higher the ratio compared to others, the better the system is.
Energy labeling is a new way of allowing consumers to easily compare and rate the efficiency of air conditioners and systems as per the stringent government and environment norms, the higher the star rating, the higher the efficiency. For more information kindly visit www.bee-india.nic.in/
