Tips For Storing an Air Conditioner for Winter

by Jonathan Cogley

Once you are done with the usage of air conditioners in the spring and summer, it is time for the arrival of winter, when you don’t need the air conditioners. So, it should be stored in a safe place where it won’t get damaged from dirt, dust and other debris.

Following are some of the tips that will help you store your air conditioner for the winter:

  • Make sure your air conditioner is unplugged and turned off.
  • Remove and keep it on a towel as there may be some water in the air conditioner. Placing it on the towel will absorb the water instead leaking it all over the floor.
  • Cleaning of indoor unit requires more work. It often requires a professional help. However, if you want to clean it by yourself begin with the filters of the air conditioner. Remove and clean the filters with warm water, you can also add some detergent in water. An old toothbrush or vacuum’s brush should be used to clean the filters. Make sure that the filters dry completely.
  • Out door unit should be cleaned once in a while. This is often ignored by many people. However, clean the outdoor unit with the help of a cloth or a sponge.
  • When trying to store your air conditioner, store it in the sheltered box as there is a risk of mice and rats chewing the wires. Make sure that the place you are storing is dry and away from direct sunlight.
  • To prevent damage to the appearance of the air conditioner, store it in its original box.
  • Store it in a proper position. It should be stored in upright position. If it is not stored properly it may damage the compressor and other parts of the air conditioner.
  • If you are not willing to remove the air conditioner, better to caver it. Covering your air conditioner will increase the life of the appliance. Use a winterizing cover to wrap your air conditioner as it will keep the appliance in good condition thereby protecting it from outside environment. It is better to measure the size of the air conditioner before buying a cover.

Know How to Select the Right HVAC System for Your Home

by tocuser4

Centrifugal FanChoosing the right HVAC system for home is a complicated task and does not involve a single component to look after. It is an assembly of technologies that establish comfortable environment where you and your family members can live healthy. While investing on HVAC system, you need to reconsider a range of issues from its efficiency to getting comfortable environment in you home. This article discusses choosing best HVAC system for your home.

We rarely think about how to save money while installing HVAC system. Purchasing high performance (it does not mean to invest much to get a sophisticated HVAC; it means to get the system suitable to your home to create comfort) HVAC system is good at reducing overall energy consumption and to save money. While buying HVAC, you need to consider size of you house, size and capacity you need. If you buy an undersized HVAC, it will not give you adequate cooling during summer. Similarly if you buy overs-sized one, it will affect the comfort levels like improper humidity levels which consume more energy. You need to do the following tasks.

Measure size of your home
Poor sizing of your home and capacity of HVAC system will cause discomfort in terms of health and raising cooling/heating bills. In order to measure your home, you need to do simple math for calculating the area of your home like multiplying length, width and height of each room including basement, upstairs and attic. When you sum the area of each room it gives you will get total area of your home. Measure the exact size of you home in square footage and check with the companies that offers “home sizing and energy-audits” to identify the exact cooling capacity needed for your home. Professionals look for other parameters like doors, window, insulation and climate data of your place to fix accurate size of your home.

Calculate the amount of cooling required to your home
You may heard about BTUs (British Thermal Units) or tons. Do not bother about these terms and its science. BTU tells you about the amount of energy required to cool your room. You just need to know how much BTU is sufficient. A minimum 20 BTU is necessary to maintain cooling or heating per square feet. Multiply the area of your home with 20 BTU, gives the amount of energy required to cool your building. With this estimate you can check HVAC systems that is sufficient to provide cooling your building. Similarly calculate the heating capacity by considering 40 BTU as a unit and (minimum heating per square foot) multiplying it with total area of building.

Think about duct work
Air ducts are vital components as they provide ventilation to maintain humidity levels and you need take additional care before planning for duct work. Find out if any prior permission is needed before going for installing air ducts from building control departments.

Air ducts are sealed in walls of basements and ceiling and it is often cumbersome to maintain them regularly. A well-designed and sealed air duct is necessary to make energy efficient. While buying air ducts, go for those that are resistant to mold, dust and biological contaminants. Make sure you get enough air duct sealing, which helps you improve efficiency of HVAC. When air ducts are not good, you may experience difficulty in getting cool or heat and it might result in around 20% of loss of energy.

Look for high efficiency in HVAC systems
While looking for best HVAC systems, you need to check two parameters SEER and SHR. These parameters tell you how seasonal energy efficient is the HVAC.

SEER (Seasonal Energy Efficiency Ration) tells about cooling efficiency in per kilowatt power utilization in summer. The minimum federal standards must be at least 14 SEER. The higher the SEER is, the higher is HVAC unit’s efficiency.

SHR (Sensible Heat Ratio) indicates efficiency of maintaining humidity or moisture (cooling/heating load) in your home. The higher the number, the less is capability of HVAC system to remove humidity. The minimum levels of SHR on HVAC should be seven. For heating pumps, there is no need for heating efficiency as there is single standard for nation wide.

Whether you are planning to purchase new or a sued HVAC system, you need to think of its usability and budget. If possible, hire a capable contractor who can provide you efficient design and install quality HVAC system.

Necessity of Indoor Air Quality for Hospitality Industry

by Dov Waxman

Many studies has proved that the level of contaminants in the indoor air is higher than outside air. For hospitality enterprises, most problematic area in respect to entire air quality is tobacco smoke. There are four ways in which the air contaminants can be lessened like elimination, isolation, filtration, and dilution. The best approach is to eliminate the source, and the next best is isolation. Filtration removes the gases and particulates released by tobacco smoke, while dilution accomplishes the same by increasing the exchange of outside and inside air.

Poor air quality inside the restaurant can have the consequences like loss of worker’s attention and productivity, deteriorating health effects, increased building energy and maintenance costs. Poor air quality in the hotel is indicated by dry or moist air conditions. This may cause problems like oxygen deficiency, which leads to tiredness, respiratory problems and increase in mold spores etc.

Air quality inside the restaurant can be improved by introducing the fresh air in to the restaurant which in turn can be done by the following ways:

  • Cleaning all the parts of air system- Regular cleaning of parts of the air systems like coils, fans, ducts helps in improving the air quality.
  • High Ozone shock treatment- To kill any remaining bacteria or mold in the room, it is necessary to give a high ozone shock treatment.
  • Installing Air Purifying System- An air purifier helps to remove the contaminants present in the air.
  • Upholstery on the sofas, chairs, carpets etc must be cleaned regularly.
  • For keeping the room healthy for allergy sufferers, mattresses and pillows should be covered to prevent dust mites.

Implementing above said methods increases the indoor air quality and is beneficial to both employees and restaurant management. They provide safe and clean environment for the customers and also gives competitive advantage to the business.

Know About Functions Of Air Purifiers

by Andrew Veazey

An air purifier should have the capability of removing and absorbing many pollutants present in the air. Air cleaners are majorly used in enclosed environment and also used in gas compressors and gas turbine. The best electric air cleaner is the one which has the combination of few different technologies.

Air purifier has many functions to perform. Below are the some of the functions performed by them:

In engines:
Air cleaner that is present in engines stops the production of coarse particles in engine’s cylinders because release of these particles can cause mechanical disturbance and oil contamination. Air purifiers are fixed near the throttle of the engine to clean the place so that the clean air goes in.

Removes Airborne Particles:
An air cleaner removes airborne pollutant particles from the air and keep the home free of toxic environment. The technology used in air purifiers removes 99.7% of dangerous substances.

Eliminates Odor:
A quality air cleaner removes odors from an indoor space with the use of activated carbon filters, which are more efficient than other types of filters in absorbing odor. Oxidant known as ozone also absorbs the odor and also destroys odor causing air pollutants. In some air cleaner both carbon filter and ozone technology is present to remove the odor.

Eliminates Smoke and Chemical Fumes:
The other function of an air cleaner is to remove smoke, and any chemical fumes from solvents, paint, heating or cooking gas. An activated carbon filter absorbs smoke and chemical fumes. A HEPA filter can eliminate smoke, but is not effective at eliminating chemical fumes.

The Reasons that Encourage You to Use Air Purifiers

by Debbie Harry

Generally people purchase air purifier in order to make their surrounding healthy. Air purifier, purifies the air and removes the contaminants from air. There are some reasons why people need it, such as:

Clean the air: Sometimes the air in your home is more polluted than outside. Sometimes in summer, in order maintain the coolness of an air conditioner, we close the windows and doors. If it is winter people, close the doors and windows to avoid the cool air from outside. So you do not get fresh air from outside. In these cases, air purifier works well. It removes the indoor pollutants and leaves the room with fresh and clean air.

Healthy family: People want their family to be healthy, but they do not realize that the air in their home can cause health problems. If we inhale the toxins into our bodies, we may suffer from illness or many lung diseases. This can be one of the reasons to use the air purifiers. Air purifier removes the harmful toxins from the air and provides healthier environment.

Relief from asthma: Asthma patients majorly suffer due to the pollutants present in the air. The pollutants, present in the indoor air also contribute to allergy and asthma diseases. So using purifiers can help to remove pollutants from the air and helps in bringing relief to the people.

These are some of the reasons which are encouraging people to use the air purifiers.
