On last 16th November, 2017 we have handover one of our HVAC project regarding 550 TR to its owner as NJM Committee on Dhanmondi; with the presence of our Honorable Managing Director Mr. Hafiz U Biplob and Director Mr. Khaled Mohammed Ali Manik. Also our Manager (Tech,) Mr. Mohammad Imran Khan, Manager (S*M) Mr. Kaushik Rabu, In charge of Service & Maintenance Dept. Mr. Saiful Islam, Asst. Engr Jabir Hossain was there.

The goal of project management was to obtain client acceptance of the project result that we have managed on our HVAC works for Nur Jahan Market, Mirpur Road Dhaka. This means that the owner agrees that the quality specifications of the project parameters have been met. In order to make this go smoothly, the owner and project management committee must have a well-documented criteria of performance in place from the beginning of the project. This information should be documented in the project management plan which should include all changes requested through the life of the project.

Our Objective, measurable criteria are always best, subjective criteria are risky and open to interpretation. There should be no room for doubt or ambiguity, although this is often difficult to achieve.

Also we have meet together in a wonderful evening and had handover the full project in a compilation with satisfactory.

It was really a cheerful evening that all enjoyed with delicious food and warm company.

An air conditioner's filters, coils, and fins require regular maintenance for the unit to function effectively and efficiently throughout its years of service. Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases.

Conditioner Filters:

The most important maintenance task that will ensure the efficiency of your air conditioner is to routinely replace or clean its filters. Clogged, dirty filters block normal airflow and reduce a system's efficiency significantly. With normal airflow obstructed, air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil's heat-absorbing capacity. Replacing a dirty, clogged filter with a clean one can lower your air conditioner's energy consumption by 5% to 15%.

For central air conditioners, filters are generally located somewhere along the return duct's length. Common filter locations are in walls, ceilings, furnaces, or in the air conditioner itself. Room air conditioners have a filter mounted in the grill that faces into the room.

Some types of filters are reusable; others must be replaced. They are available in a variety of types and efficiencies. Clean or replace your air conditioning system's filter or filters every month or two during the cooling season. Filters may need more frequent attention if the air conditioner is in constant use, is subjected to dusty conditions, or you have fur-bearing pets in the house.

Conditioner Coils:

The air conditioner's evaporator coil and condenser coil collect dirt over their months and years of service. A clean filter prevents the evaporator coil from soiling quickly. In time, however, the evaporator coil will still collect dirt. This dirt reduces airflow and insulates the coil, reducing its ability to absorb heat. To avoid this problem, check your evaporator coil every year and clean it as necessary.

Outdoor condenser coils can also become very dirty if the outdoor environment is dusty or if there is foliage nearby. You can easily see the condenser coil and notice if dirt is collecting on its fins.

You should minimize dirt and debris near the condenser unit. Your dryer vents, falling leaves, and lawn mower are all potential sources of dirt and debris. Cleaning the area around the coil, removing any debris, and trimming foliage back at least 2 feet (0.6 meters) allow for adequate airflow around the condenser.

Fins:

The aluminum fins on evaporator and condenser coils are easily bent and can block airflow through the coil. Air conditioning wholesalers sell a tool called a "fin comb" that will comb these fins back into nearly original condition.

Drains:

Occasionally pass a stiff wire through the unit's drain channels. Clogged drain channels prevent a unit from reducing humidity, and the resulting excess moisture may discolor walls or carpet.

Seals for Room Air Conditioners:

At the start of each cooling season, inspect the seal between the air conditioner and the window frame to ensure it makes contact with the unit's metal case. Moisture can damage this seal, allowing cool air to escape from your house.

for Winter:

In the winter, either cover your room air conditioner or remove and store it. Covering the outdoor unit of a central air conditioner will protect the unit from winter weather and debris.

a Professional:

When your air conditioner needs more than regular maintenance, hire a professional service technician. A well-trained technician will find and fix problems in your air conditioning system.

technician should:

- Check for correct amount of refrigerant
- Test for refrigerant leaks using a leak detector
- Capture any refrigerant that must be evacuated from the system, instead of illegally releasing it to the atmosphere
- Check for and seal duct leakage in central systems
- Measure airflow through the evaporator coil
- Verify the correct electric control sequence and make sure that the heating system and cooling system cannot operate simultaneously
- Inspect electric terminals, clean and tighten connections, and apply a non-conductive coating if necessary
- Oil motors and check belts for tightness and wear
- Check the accuracy of the thermostat.

CLEAN AIR IS A KEY COMPONENT OF A HEALTHY HOME.......................................................................................................
- As part of your home heating and cooling solution, they can help reduce or even ELIMINATE many ALLERGENS and HARMFUL AIR POLLUTANTS – from DUST and PET DANDER to CHEMICAL FUMES and MOLD.

- CONTROLLED ROOM HUMIDITY.

- Frequent FILTERING.

- GOOD VENTILATION is important, as it will bring in fresh, clean air into your home.

- WEATHER PERMITTING, try to keep the windows open for a while every day, especially in CHILDREN’S bedrooms.........................................................................................................

CLEARING THE AIR

There are several steps we can take to improve our air quality. Generally, controlling or removing the sources of pollution is the most effective measure you can take. Have your stove and furnace serviced to reduce emissions. Keep your floors clean by vacuuming and mopping. Avoiding scented sprays, polishes, deodorants, soaps and detergents will also reduce the amount of chemicals in the air.

Good ventilation is important, as it will bring in fresh, clean air into your home. This is especially important when using any chemicals or cleaning supplies. However, it is very beneficial at other times as well. Weather permitting, try to keep the windows open for a while every day, especially in children’s bedrooms. It’s not only pleasant, but some of the bad air will literally be blown away.

Air filtration systems can be useful, but their effectiveness is based upon their size and the quality of the unit. Also, check and see what a filter will remove, as many do a good job of filtering dust and pollen, but do not remove hazardous gases.

For a simple and attractive option, did you know that houseplants actually filter many toxins from the air? Besides acting like miniature air purifiers, they are completely natural. NASA has actually been researching the effect plants have on the air for some time. While their goal is to find ways to keep the air in space stations habitable for long periods of time, we can easily apply their findings to our homes and offices.

NASA studies showed plants to be effective at removing harmful elements, like benzene, formaldehyde and trichloroethane, from the air. These elements are more common than you may think. For example, formaldehyde (which is a leading cause of asthma) is found in thousands of consumer products including textiles, cleaning products, construction materials, paper products, cosmetics, fertilizers, and plastics.

While it is likely that all houseplants purify the air to a certain extent, there are some that excel more than others. It would be ideal to have an assortment of different plants placed throughout the house.

Fortunately, the majority of the plants NASA tested were common household plants and should be easily available at your local nursery.

Some of the best plants for removing formaldehyde included: Bamboo Palms, Janet Craig Dracaenas, Mother-In-Law’s Tongues & Marginatas.
For removing benzene: Gerbera Daisies, Pot Mums, Peace Lilies, And Warneckei Dracaenas.

For removing trichloroethane: Gerbera Daisies, Marginatas, Peace Lilies, and Janet Craig Dracaenas.

Other good plants include: English ivy, Rubber plants, Weeping figs, and Boston ferns.

So pick up some plants and add some freshness to your air and to your décor as well.
