Many buildings are equipped with inefficient air-conditioners, which results in air-borne disease, health problems and uncomfortable environment. Today, we have most modern technology in HVAC systems that can ensure adequate fresh air, controlled heating and cooling environment. This article seeks to explain the HVAC system and its functions.
HVAC is the acronym for “Heating, Ventilation and Air Conditioning” systems, designed to meet home to industrial purpose. HVAC perform four main functions – heating, cooling, ventilation and controlling humidity levels (moisture). They are quiet and considered to be reliable in providing comfortable human conditions.
Earlier, HVAC industries began with oil and gas burners and quality of air-conditioners was regulated by manufacturers. But since the 1900s HVAC industries came with many advancement in furnace technology, high pressure heating systems, high speed centrifugal fans and coils for dehumidifier to improve effective cooling heating and ventilation.
Advancement in technology helped HVAC provide quality, efficient and cost effective air-conditioning equipment to consumers. Today, different organizations have come forward to maintain uniform standards and quality around the globe for improving HAVC system, implement research and share knowledge.
HAVC systems are necessary to maintain room temperature under different climate conditions and are sometimes referred to as climate control. Though there are many HVAC systems, all designs are meant to provide adequate air quality, circulation of fresh air, maintaining room temperature, control over humidity levels and ventilation.
A HVAC system provides two stages of heating or cooling the building using water and air as medium. Water is used in cooling and heating as it is an inexpensive source and can efficiently cool room using chillers and heat using boilers. While air is used as medium to cool or heat the room air condition by use of heating and cooling coils.
The basic functions of HVAC units – Heating, ventilation and cooling
HVAC are provided with heat pump devices for both heating and cooling the rooms. This works on principles of refrigeration but it works in opposite way. Heat pumps draw heat from the outdoor environment and circulate the hot air in the buildings. But, drawing heat from outdoor freezing environmental condition is uneconomical. Heat pumps that use electricity are more reliable and economical in pruning electricity bills by 30-40%. The advantage of heat pumps comes by reducing the need for purchasing other heating devices.
Ventilation involves continuous exchange air between outdoor to indoor, removing humidity, combustion smoke, smell, dust and even small biological agents (bacteria, mold). Ventilation plays an important role in maintaining indoor air quality, health of people inhabiting the building, which extends life of buildings and avoids stagnant indoor air. HVAC systems provide ventilation by allowing exchange of air from both indoor and outdoor buildings environment. This circulation is controllable in providing air quality.
Though air conditioning the entire building is expensive, it is necessary to maintain to improve health and working efficiency in houses or office building’s. Air-conditioners are equipped with indoor (evaporator), outdoor (condenser, compressor) units and a refrigeration line connecting both units. This refrigerant (gas) assists air-conditioner devices to remove the hot air from building’s to provide cooling environment.
The use of HVAC systems is on the rise since it provides comfortable human temperature, controls infections, improves health and efficiency at workplace, etc.
An air conditioner is an equipment that regulates and maintains temperature and humidity in the home or office environment. According to Heating, Ventilation and Air Conditioning (HVAC) experts, comfortable levels of human body temperature is 25O Celsius and 50% humidity. All air conditioners work by simple principle of conversion of refrigerants from gas to liquid and vice versa.
This conversion of refrigerants helps in dissipating heat from the room and this in turn causes cooling effect.
In the beginning of 1900s, the first air conditioning unit was invented by Willis Carrier at New York. His invention aided in development of most advanced air conditioners for providing clean and comfortable room temperature in homes, offices, shopping malls, theaters and everywhere. In this article, we will discuss about the types of air conditioners and their pros and cons in using them.
The choice of air conditioner depends on factors such as size of home/office, cost, installation requirements, energy efficiency, etc. Depending on the purpose ranging form domestic usage to industrial, the following types of air air conditioners are available.
Room air conditioners
Room air conditioners are installed on specially cut opened areas on the wall or windows. Room air conditioners have a single unit where all parts compressor, condenser and evaporator are placed.
Room air conditioners are efficient for single rooms. They are economically good in terms of saving energy and money. It is easy to handle and install them. The disadvantages are its inefficiency in maintaining room temperature and humidity. They are also noisy and are not aesthetically appealing.
Portable air conditioners
Portable air conditioners are alternative to room air conditioners. Easy to shift from one room to other. Portable air conditioners are perfect for those who cannot afford duct works and other regular maintenance. In addition, these are equipped with dehumidifier, fans and heaters to adjust room temperature conditions. Portable air conditioners are good for people who are living in extreme humid weather conditions.
Split air conditioners
Split air conditioners have two units – an outdoor (condenser and compressed) and an indoor unit (evaporator). Indoor unit is responsible for removing hot air and humidity from the room, while outdoor units help in pumping out the hot air outside. Split air conditioners are good in controlling or heating one or two rooms.
Split air conditioners are good in appearance, designed to occupy less space on wall. There is no need of special slot on wall or window and are more efficient than room air conditioners in controlling temperature and humidity.
Ductless air conditioners
Known as mini-split air conditioners, these are good for those who do not like to go for duct work on walls or where the room is not suitable for duct work or the room is without windows. Ductless air conditioners have aesthetic appearance, compact, occupy less space, extremely quite and reliable technology. Installing ductless air conditioners is very simple and needs few electrical work.
Central air conditioners
Central air conditioner are good at providing cooling for larger houses, malls, theaters, hotels and any other type of large buildings. Central air conditioners are reliable in maintaining a constant temperature, moisture levels, quality of air and is good to have one when your budget and space permit.
There are two types of central air conditioners – split system and package unit. Split system contain refrigerant (gas) drain line that circulates refrigerant in both outdoor (condenser and compressor) and indoor units (evaporator and blower).
The indoor unit is equipped with blower that makes circulation of cool air around the house. Split system of air conditioners gives efficiency in cooling in economic way. Where as package units has both the evaporator, condenser are placed outside and cool or hot air is passed through furnace inside the buildings.
The object of an air conditioning equipment is to make stay comfortable by controlling humidity and maintaining the temperature at optimal level. It depends on the type of home you live on while opting for a certain kind of air conditioner.

Any person who met with a car accident with or without fault might have experienced severe injuries, or sometimes death, and also resulted in damage to the car. However, any driver who is severely injured in an accident can file suit against the other driver for various reasons. If the accident left the person disfigured or scared, the faulty person must pay for injured persons medical expenses as well as those that a doctor feels and says that will arise in the future. The injured person can also get compensated for the emotional suffering caused by injuries.
If you are injured in an accident and filed a case against a faulty person and you have won, you should be compensated for permanent disability, pain, emotional anxiety, medical expenses and surveillance, lost wages, lost work or earning capacity, loss of consortium or society, and household services you cannot take care of while you are injured.
If the faulty driver was not negligent but reckless, they may have to pay more compensation. Speeding, excessive lane changing, not signaling intent to change lanes, changing lanes when there is no safe way to move, passing on an emergency lanes, and with drunk driving comes under reckless driving.
However, drunken driving cases are especially horrible and terrifying. An accident lawyer will tell you whether you should file suit, or not just against the drunk driver but also the server or business that gave the driver so much alcohol.
There are some special cases which are caused by a defect in the car of a driver. If a defective product causes the accident, the manufacturer is responsible for the negligence.
Recently Consumer Federation of America published a guide, “Navigating the Auto Claims’ Maze: Getting the Settlement You Deserve.” This guide helps the drivers navigate the claims process and avoid getting unpaid or less-paid for their claims. It also provides some useful tips on filing claims with others’ driver’s insurance company when you are not at fault.
A claim is a request that you make to your insurer to pay compensation for sustained damages in the accident. So in order to get paid for your claim, you need to consider some important things before filing an auto insurance claim.
Report the loss
You need to contact your insurance company after an accident as soon as possible. Because, your insurer cannot begin the claims payment process until you inform about the loss. Also, remember before you hang up the phone, you need to ask the name of the adjuster who is being assigned your claim.
Check whether you have coverage for the damaged
Ask your insurance company whether or not the accident is covered in your insurance policy. Your main responsibility under your insurance policy is to provide the information and make your vehicle available to the company for any damages appraisal.
Ask your insurer what documents you need to submit to them to support your claim. Also, you need to submit accident report from the police. If you want to get compensation for your medical bills, you need to show receipts of receipts of accident-related expenses.
Schedule an inspection
The insurer schedules a date for inspecting your damaged vehicle. You need to deal with the adjuster and they will estimate the losses and your car get repaired. You can also discuss injury and medical treatment if you have received in the accident.
Because of lack of knowledge of making claim and lack of confidence, many people hesitate to claim. For those also the insurers are obligated to entertain their claim. It does not make sense to purchase insurance, if it does not help you when you deserve to get it. Thus, you need to claim properly to get your problem resolved and paid for your damages. More >
