How Does an Air Conditioner Work?

During the hottest months in Singapore, homes and offices will be relying more on the cooling power of the airconditioning systems but the increased and continuous use will also expose the units to some of the common issues. Knowing how the air conditioner works, however, will help you determine whether the system needs to be calibrated by an aircon maintenance crew or if there are minor problems that need to be addressed soon to avoid major aircon repair projects.

Let’s break down the processes that involve the absorption and casting out of heat and the production of cool air.

Parts of an Air Conditioner

There are five basic components of an air conditioner. When your aircon repair crew from Singapore checks on your unit, the following parts are inspected first.

  • Thermostat – This regulates the temperature of the air blown out of the air conditioner as well as the heat flowing inside the unit. Regular aircon maintenance is needed to make sure that the thermostat is calibrated because it’s prone to a lot of problems especially if it’s an automatic or digital type thermostat.
  • Evaporator – This unit is linked with the condenser through a pipe and is responsible for transforming high-pressure gas into low-pressure liquid. The refrigerant will take the heat from the air and then cool it off, so that when the fluid come out as gas form from the evaporator, the gas is compressed in the compressor.
  • Compressor – The aircon maintenance technician from Singapore will help review cold air ventilation systems by doing a thorough aircon servicing and checking of parts, including the compressor. This is probably the most important part to check when doing an hvac preventive maintenance, because this is where the gas is transformed into liquid during the cooling process. The low-pressure gas is converted into high-pressure and energized gas. The refrigerant, the liquid form then comes out of the compressor and transported to the condenser.
  • Condenser Coil – The fan in the condenser coil is responsible for cooling down the high-pressure gas and converting it into liquid form. After this, the liquid is transported to the evaporator. This part of the aircon conditioner system should get regular aircon servicing because most aircon type place this part outside the house or the room. It suffers from wear and tear because it is constantly exposed to the elements. Regular aircon maintenance will prevent the fan from wearing out or getting clogged, too.
  • Blowing Unit and Air Handler – The air handler draws the warm air from the room while the blowing unit distributes the cool air. In commercial buildings, an extensive duct system is needed to ensure that all the areas get the same quality of cool air. Regular aircon servicing of a complex air conditioner system is crucial to avoid major aircon repair expenses.

How the Aircon Cools the Room

Regardless of the type of aircon you have, they allserve the same purpose of regulating cool air into the room. However, for offices and large spaces in Singapore with multiple rooms, it is recommended to build in new central AC system. A shared aircon system is much moreefficient than stand-alone units for every room. Centralized aircon cools allspaces at once while running in a single system.

To better understand the process, let’s divide the process into two parts based on the location of the aircon parts; indoor and outdoor.

The indoor aircon unit includes the evaporator and the coil box which are responsible for the evaporation and absorption of heat. The cooling fluid is located in the coil piping, allowing the refrigerant and water to turn into vapor as the unit absorbs the heat.

The outdoor unit on the other hand disperses the heat collected in the room or building, that is why if you pass by some large commercial and industrial buildings, there are sections with large fans that blow off warm air. The fan, compressor, and condenser coil are located in the outer unit.

From the indoor unit, the refrigerant is transferred to the outdoor coil and compressor. So, what happens to the used refrigerant? The compressor recycles the refrigerant so that it can keep absorbing and then cooling the air from the room. The refrigerant is compressed so that it becomes high-pressured and then moves into the outdoor coil or condenser so that when it reaches the fan, the warm air is cooled in the condenser coil.

From this process, it would be safe to assume that the air conditioning process is not about cooling the air, but more about collecting warm air and dispersing it outside of the room or building. The process begins when the thermostat detects that the temperature of the room is different from the information you feed it when you change the temperature. It will continue to monitor the temperature in the room to maintain the coolness.

To simplify the process, remember that the warm air passer first throughthe condenser coil, then the expansion valve, next the evaporator coil wherethe air cools, and then the compressor. The process then repeats again and again until there is no warm air that can be cooled.

This constant process therefore exposes the unit to a lot of problems, that is why regular aircon servicing is important if you don’t want your office operations to be interrupted by a faulty system. Some of the common problems in air conditioner include leaks, low refrigerant levels, dirty filter, electric control issues, sensor problems, and dirty or clogged drains.

Energy-Efficient and Earth-Friendly Aircon

Like most electronic appliances and gadgets, the air conditioner system uses a lot of energy that is why commercial buildings consume more energy because they have larger and more complex aircon systems. To reduce your electric bills and to prevent other common aircon problems or if your aircon system is already ten years old or older, your aircon technician in Singapore might recommend that you choose energy-efficient models which up to 50% less energy than the older models. However, the same cooling efficiency is guaranteed, plus there are tons of new features that you can also enjoy. Regular aircon servicing will also guarantee that your air conditioning system will function efficiently and optimally all the time.

Common International Freight Mistakes and How to Avoid Them

With the increased demand for companies to operate globally, it is more important to secure ways for seamless international trade. Of course, international freight forwarding is a complex service—with many different regulations and security to follow and countless of moving entities to ship goods from one point to another.

Whether you are someone who ships one container a month or 10 containers a week, it helps t be aware of the common mistakes shippers make when working with a freight forwarding services for transportation of goods.

Mishandling the Time of the Shipment

Like any other things in life, timing is key for international shipping. Estimating the shipping time can be tricky, making this a common international freight mistake, especially among smaller businesses.

Perhaps, you want your goods to be shipped fast. You ask for a quote and find out that the shipping time is more than two weeks. If you promised your goods will arrive sooner, this is going to cause you a serious problem.

Generally speaking, if you want your goods to arrive in the destination faster, have it shipped by air. But keep in mind that air freight is more costly than sea fright and is more ideal for shipping small- to medium-sized shipments. For your larger cargoes, give it more time to transport as it is safer to be shipped by sea freight.

How to Avoid: Researching the shipping time of a freight forwarder to deliver shipments, whether for outside or just within Singapore, is a crucial step to take when working with a cheap clearing and forwarding agent. You can conveniently look it up online, and you will get a decent estimate of how many days it will take to import and export goods to certain destinations. For more accurate details, talk to a reliable freight forwarding agent.

Another way to avoid miscalculations of resources is to get a freight quote within the month of the shipment date. Shipping rates vary all the time, but as a general rule, rates change every month. So, prepare the goods to be shipped, have the details ready for your shipping company, and request for a rate within 30 days before the scheduled transportation of cargoes.

Uninsured Goods

Stolen or damaged goods are a common scenario. The ship may crash, encounter a storm, attacked by pirates or be on fire. All these things can possibly happen anytime. Usually, shippers improperly insure their goods or even skip getting a cargo insurance altogether.
Also, many do not know that there are different types of insurance for different types of goods. For example, household items require to be packed by a professional in order to be insured. Being clueless with such things can result to worthless insurance.

How to Avoid: Discuss about getting an insurance with your freight forwarding company, and make sure to clarify the conditions of it. Most freight forwarding services have insurance, so it is not entirely necessary to outsource your cargo insurance, whether for an international or local freight.

When discussing about the matter with your logistics company, do not forget to mention the type of goods included in the transportation, what are and are not included in the insurance coverage and any special provisions of the offered insurance policy.

Skimping On the Most Important Factors

In relation to the previous freight error, ignoring other important factors when choosing a logistics company for the transportation of your goods can result to horrendous and more expensive delays.

How to Avoid: One thing to help you decide which company to approach is to determine your priorities. When choosing a freight forwarding services provider, keep in mind your budget, timeline and any regulations associated with the transport of your goods. If the cost is the primary concern, then sea freight is the best solution. If One thing to help you decide which company to approach is to determine your priorities. When choosing a freight forwarder, keep in mind your budget, timeline and any regulations associated with the transport of your shipment. If timeliness is critical, especially if it is for your business here in Singapore, then delivery by air plane is the way to go. Air freight may be a bit expensive, but it is the fastest and probably the safest way to ship your goods. If cost is the primary concern, there are also other shipping methods you can choose from. For FDA-approved items, there are separate documentations and regulations for that as well. The best thing to do is to seek professional assistance from a logistics services company to ensure efficiency and legality of the shipment.

Transferring of goods internationally is one of the most crucial parts of handling a commercial business. By being savvy with the ever-changing international regulations and working with a certified international freight forwarder, it is easier to avoid these pitfalls and avoid any risks associated with global shipping.

Going For the Cheapest Freight Rate

This is the most common mistake among international shippers. You are a business owner about to ship a large amount of goods and make a good profit out of it, so you shop around and find the lowest international freight rate possible, and go with that freight forwarder.

However, remember that the rate is not the only factor to consider when choosing a freight forwarding company. Freight Master does their best to provide the best logistics services for a reasonable price for your freight forwarding needs to and from Singapore; but ultimately, they go the extra mile to give you smooth-sailing shipment of your goods.

Going for the company with the cheapest freight rate may even cause more costly problems if your cargo gets delayed, lost, damaged or held up at customs. As what they say, you get what you pay for.

How to Avoid: One of the ways to confirm the experience of a company in the freight forwarding business is to find out how long they have been in the industry. There is a big difference in the performance of a year-old company and a seasoned logistics company who has been operating for decades. However, make sure to check closely if the company who has been operating longer have good track record. Being in the business for longer time does not necessarily translate to excellent services. Read reviews and see for yourself if the company can truly deliver.
