ETRCO (Engineering Technical Refrigeration Company LLC) was established in Al Ain-UAE in 1996, starting as an HVAC solution provider undertaking supply, installation, servicing, diagnosis and maintenance of equipment such as centrifugal chillers, absorption chillers, screw chillers, reciprocating chillers, package units, airside equipment and solar panels. A division opened in our company in 2011 for lighting control and irrigation. Since then, our company has opened a home automation division dealing with KNX and smart home systems. Our Joint ventures and partnerships with various leading contractors and suppliers all over the world have led us to deliver sophisticated state of the art systems and technologies to clients with the highest quality standards.
The four main components to your air conditioner are:
Condenser: The condenser is the outside metal unit and where the gas from the compressor is condensed into a liquid. The gas entering the condenser is very hot. The temperature is then lowered, so the gas can convert back to a liquid.
Compressor: The compressor is inside the condenser. It circulates the pressurized refrigerant, to concentrate the heat, and changes the low-pressure gas to high pressure.
Evaporator: The evaporator is the part of the system inside the home. In simple language, it absorbs the heat from your home.
Expansion Valve: The expansion valve controls the amount of refrigerant in your system.
All of these pieces are connected by a copper tube that handles refrigerant, creating a closed loop. Heat is collected in the evaporator, sent outside to the condenser. The heat is removed, and the cool air is recirculated back into your home.
An Air Conditioner Doesn’t Create Cool Air.
What happens in the AC process is actually the removal of heat from the air. Your AC uses a chemical called refrigerant to remove heat and transfer it outside. The warm air runs through the lines and coils in your unit and goes from liquid to gas and back again. During this process, the refrigerant removes the heat and transfers it elsewhere so that when the air comes out the other side, it is cool.
Your AC Will Remove Humidity.
Lower humidity helps the overall comfort level in your home by making you feel cooler, even if the temperature is the same.
Your Air Filter Needs To Be Checked And Replaced Every Three To Six Months. (depending on the manufacturer’s recommendations)
A dirty air filter restricts your air flow, which reduces efficiency, costing you money, and over time can put stress on your unit and could cause a costly repair.
Maintenance, Maintenance, Maintenance.
Your air conditioner needs regular checkups to keep it running in tip-top shape. Having regular annual preventative maintenance will bring your system longer life and fewer breakdowns overall.
On average, people spend 90 percent of their time indoors but don’t know that indoor air can be two to five times more polluted than outside air. The EPA (Environmental Protection Agency) has indoor air quality ranked as one of the top five environmental dangers to public health. It is linked to severe asthma and allergy development in children and to heart problems and lung cancer in children and adults.
Indoor Air Quality
What are symptoms of poor indoor air quality?
Symptoms of poor indoor air quality depend on the particular contaminant and are sometimes mistaken for allergies, stress, colds, or flu. Some of these associated symptoms are coughing, sneezing, fatigue, dizziness, headaches, nose bleeds, sore throat, and upper respiratory congestion. Your air quality can also contribute to the development or the aggravation of some more serious conditions including infections, lung diseases, asthma, and heart disease.
What are some causes of poor indoor air quality?
Indoor air quality is affected by anything that releases gas or particles, which include combustion, personal-care products and activities, and even outdoor air quality.
Inadequate ventilation will trap contaminated air inside and can keep clean, fresh air from getting in. If you have unmaintained heating and air conditioning systems, your clogged air filters and dirty ducts will contribute to dust and mites in the air. Dampness in your house caused by floods, leaks, high humidity, or an unmaintained humidifier or dehumidifier can create mold and bacteria. Call ETRCO for help in detecting the possible sources in your home.
You may be polluting your own air!
Your own activities can contribute to the pollutants in the air. Cleaners and personal-care products are high culprits for this. Do not smoke inside. Cigarette smoke contains 7,000 chemicals and 69 poisons known to cause cancer. Children and elderly people are particularly sensitive to this, but it is unhealthy for everyone.
Burning of any kind of fuel releases particles into the air. Adequate ventilation is necessary to keep these contaminants under control.
