How To Maintain Thermal Comfort In A Home

Do you feel uncomfortable with the temperature in your house? Are using an air conditioner? Then you must check several factors that may affect its performance. Thermal comfort is an important issue that needs to address properly. Lacking this comfort can cause stress on the occupants. When you are too cold you became restless while when you are too hot you feel so tired. If you want to maintain temperature comfort in your area, it is important to monitor the actual air temperature, humidity, and the movement of the direction.

Everyone has their temperature comfort zone and it means that there is no ideal temperature for all times. According to the experts, the recommended temperature at home is between 69 to 73 degrees Fahrenheit. You must remember that an outdoor temperature is a great factor in setting your temperature. If you notice that it’s too hot on the outside, avoid setting your thermostat at a low temperature. This will lower the temperature difference when entering the house.

Maintaining temperature comfort at home is an easy job, you just need to familiarize yourself with the different factors that need to be check. You need to remember that the sunlight may affect the room temperature. It is suggested to put blinds or any window cover if it is too hot on the outside. In fact, in heat load calculation, the window size and location are great factors in determining the proper air conditioner size.

Mechanical engineers and building designers suggested considering the appliances, number of occupants, area of the house, and the number of windows in using the air conditioner. Once you master these factors, it would be easier for you to main your desire thermal comfort. Even the lightings and televisions can give heat in your area that’s why it is better to turn off these appliances once not in use. If the number of occupants increases, you must lower the temperature setpoint to provide comfortable air in the area.

A Brief Idea on Thermal Comfort

Thermal or temperature comfort simply means how warm or cold you feel. Great insulation can be installed in your walls or ceiling to maintain temperature comfort. It can block the heat from coming into your walls. Proper monitoring of temperature will not only give you comfort but also electricity savings. Proper usage of the air conditioner will lessen energy consumption. To start monitoring the actual temperature and thermostat in your area.

Do You Need An HVAC System To Have A Central Heating System?

People residing in warm or cold weathers might go for a particular stage system, designed to produce just heating or cooling. These tend to be low-priced, but are also somewhat ineffective and will characteristically be working hard even when it’s not essential.

More progressive representations will offer variable fan speeds to cut down on power use, however they remain inefficient when compared to multi-stage systems, and are thus more expensive to run over the long term. On the other hand, zoned systems are intended to warmth or cool specific parts of your household. This is completed by scheming zone valves and dampers inside the ductwork and vents that selectively block the flow of air. For people with bigger properties this is of incalculable value as it prevents the system from warming or chilling areas in the household that are not in use. HVAC systems can also be built to offer moisture regulator, and both dehumidifiers and humidifiers can be served as choices to heating and cooling systems. Individuals that reside in very dry surroundings or the tropics find these additions to the system essential. As such, specific individuals wish to install discrete humidifier or dehumidifier systems, so that they can manage the humidity of their environment without also having to turn on the air conditioner. This is why it is recommended for HVAC systems to have central heating system.

HVAC means Heating, Ventilating, and Air Conditioning. HVAC systems need to have a central heating to, effectively provide ventilation. Everything from your air conditioner at home to the large systems used in industrial complexes and apartment blocks. A good HVAC system targets to deliver warm air control and indoor ease, and one that is premeditated using the ideologies of thermodynamics, fluid mechanism, and heat allocation. The large air conditioner boxes that you might perceive on top of apartment blocks or offices are examples of the observable part of HVAC systems. They’re characteristically positioned in large business structures, multistory building, studio apartment blocks, and large interior environments. They’re also an essential component of environments where there are health protocols necessitating that temperature and moisture be kept at firm levels, using air taken from outdoor. But warming and refrigerating systems you use in your household are also HVAC systems. They may take a diverse form, but many of the central principles determining how they operate, as well as their efficiency, crosses over from the least of personal devices precise through to the prime commercial installations.

The Elements of an HVAC System

An HVAC (Heating, Ventilation and Air Conditioning) system is needed in every household to maintain a comfortable and consistent indoor environment. The system is designed to take control of the environmental conditions inside your house.

This HVAC system ensures the cleanliness of the air inside your house. It also controls the temperature of the room through heating and cooling, making it balanced depending on the weather and temperature needs. It also controls the humidity level of your house by controlling the movement and distribution of air inside.

There are three main types of HVAC systems namely split and window air conditioning, packaged heating and air conditioning system, and central air conditioning system. Usage and purpose of every HVAC system depends on the age and size of your home, the number of rooms you want to air condition, local climate, utility costs, and available services and warranties.

It is important to understand the components of your HVAC system so that you will know how to maintain it properly, so that when problems and concerns occur, you will be able to find and fix problems easily. In that way, you can prevent inconvenient and expensive breakdowns, making sure that your home stays comfortable while your system works at peak performance.

Elements of an HVAC System

The HVAC is a very complex system that has many components. It is always good to ask for help from a professional AC repair service whenever you experience problems with your HVAC system. To further understand how this system works and in order to fix light problems and concerns, it is essential to learn more about the basic elements of an HVAC system.

  • Thermostat – It is a visible device that is attached on the wall, and is used to adjust the temperature and air conditioning in your home to suit your desired preferences. A thermostat is equipped with temperature sensors that turn your heater and air conditioner on and off when necessary.
  • Furnace – It is the most important element needed during the winter season. The furnace is a big, metallic box with pipes often located in the attic or the basement. It heats the air distributed in your home, and the primary sources used in the heating process are electricity, solar pumps, and heat pumps.
  • Condenser Coil or Compressor – It is the most expensive part of an HVAC system. It cools your home by releasing heat outdoors.

Replacing An HVAC Damper: Be Sure To Buy The Right Type

 A damper is one of the most important parts of an HVAC system. If you want to have an efficient damper, you must evaluate the designs of the airfoil blade, blade seal, and jamb seal. The damper can help you in saving energy and pennies. Worn and damaged dampers must replace immediately because it may affect the performance of an air conditioning unit. There are various types of dampers in the market, so make sure to choose the right type.

The Best Damper For A Duct System

Air conditioners are very useful wherever you are. During summer, it can give you a cooling effect while in winter it gives you warmth. Proper airflow of the unit ensures you that the upcoming bills will be within your budget. An HVAC system is also vital for different establishments especially on the commercial side because it gives relief to their prospected clients. Ducting is used in huge infrastructure to properly distribute the airflow in all rooms. There are different sizes and shapes of dampers available in the market, and it can be fit on your system. It can be a rectangle damper or a square damper.

What To Consider When Buying Dampers

The zone control panel is vital when buying dampers. It is responsible for controlling the dampers and thermostats on communicating with the HVAC system. It should be compatible with all the aspects of your building. There are no smart devices that will help you to conduct the inspection, you must check it and watch out for every single detail.

Smart thermostats must be placed in different corners of the room to get the precise room temperature. A damper is commonly connected to a thermostat and it gives the signal when or where to move the airfoil blades. It will also release or control the flow of air depending on the signal of the thermostat. If the thermostat senses that the area is hot, it will give a signal to the damper to release more air and if the area is cold it will tell to control the releasing of supply air. There is also a manual damper that you can control when you feel to change the temperature in your area.

An HVAC system that releases unwanted noise must check its bypass damper. It is usually caused by the static pressure inside the ducting. A bypass damper can bleed the excess air inside the system. Choosing the right damper is important because it can help your system to last for years. It will protect the compressor from using too much power and energy.

Does An HVAC System Always Include a Humidifier?

HVAC literally stands for Heating, Ventilating, and Air Conditioning, is a system that is use at home and other industrial complexes or offices that provides thermal control and indoor comfort. The HVAC system generally controls the warming and cooling of a space and also improves indoor air quality that gives comfort to occupants of such houses or offices.

All HVAC System includes a humidifier. Well, it must be, because it is actually an integral part of the HVAC system. Many had thought that it does not come in automatically with the system. But this is a misconception since HVAC controls not only the heating and warming but as well as the humidity level of one’s space. This only shows that a humidifier attached in the system prevents the air from becoming too dry.

However, there are possibilities that HVAC system may not have humidifier or probably there is but it is malfunctioning. If this is the case, space occupants may suffer from poor air quality at home which may result to physical ailments such colds, allergies, dry skin which may lead to eczema. Some other problems that may encounter because of the absence or totally non-functioning humidifier which caused to dry air are hardwood floors may lose moisture which will result to separation of the seams, houseplants may die when it is not humid enough, and wallpaper may peel at the edges.

Now, you might be wondering if your existing HVAC system has humidifier. Don’t you worry, because it is not so difficult to spot on. Just look for a small box hanging in the furnace or ductwork beside the furnace with small electrical wire and a small water level hose attached.

If in case there is no attached humidifier, then that means the HVAC system installed will not be as effective.

In order to correct this, stand alone house humidifier may be purchased separately but it would be much better if you will have a humidifier installed together with the heating and cooling system of the house.

Please do remember though that in order to ensure the comfort and only quality air will be breathe in by house occupants, it would be better to maintain the proper moisture level at home. This can only be done if reliable and professional contractor or installer will be the one to do the job.

Does My HVAC System Have A Valve Actuator?

For almost all HVAC systems, dampers are the final control devices. Your HVAC System must have a valve actuator that is the interface between the mechanical system and the control system and are acute to accurate control of your HVAC.

Normally, more than 80% of direct digital control (DDC) outputs in the HVAC percentage of the system go to a valve actuator. If they are not situated precisely, then all other areas of the air system has to suffer. Most frequently, the torque required to move a damper is the single selection standard; accurateness is not a central matter.  A controller might not be able to compensate for improper damper or actuator sizing. The commissioning authority or TAB contractor can only some­ times set airflows to correct for glitches.

Concentration on the final control elements in the design process can solve most of these problems. Equipment sizing is very rarely a problem. The airflow system delivering most of the conditioned air to the occupants causes the difficulties.  Factory-built mixing boxes control flow with difficulty due to space constraints. The willingness of design engineers to design around some space constraints leads to systems that work only part time.

There is more intricacy and more chance for minor errors to become a major problem as the size of a project grows. Novel design ideas display a larger chance of glitches. The AC actuator moves air circulation doors to more than two positions to direct air flow for A/C vents and heating. The AC actuator is positioned below the dashboard attached to air circulation entrances in the HVAC box. Doors can control warm air/cold air blending, recirculated/fresh air control, or double area piercing. The engines can move the entrances into numerous diverse locations, or just two.

There are some approaches castoff in the locomotive industry to run the HVAC entrances or flaps for dispensing cars in compartment air. These methods include vacuum motor controlled, electric motor controlled or any blend of these methods.

Since valve actuators are necessary for your HVAC system to operate properly, therefore, you have to consider it when purchasing an HVAC. Take note that not all sellers are reliable and can be trusted. So, you have to be careful when purchasing one. In addition, you must check the equipment before you settle your payment or else, you will regret buying an HVAC right after the seller is gone.

The Benefits Of HVAC Networking For Large Buildings

Large establishments are complex and require extensive care and planning when it comes to managing their HVAC System. Big buildings intake air from outside and has varied temperature inside. Taking into account the building’s large structure, the HVAC system should be able to eliminate air, filter, and exhaust energy efficiently.

Establish your HVAC System

The biggest challenge for large buildings is how to optimize and implement a system. Thus, it is necessary to assess how the HVAC system should be.

  • Building size – evaluate the structure and identify places where an efficient HVAC networking should be focused on
  • Fuel for heating – identify the type of fuel to be used whether it is electricity, oil or gas. This provides HVAC professionals what equipment, tools and materials to work on.
  • Coolant requirement- foresee what kind of mode cooling inside would be whether it is gas, electric or mix
  • Heating/cooling manifestation – understand if the building should be cooled or heated via water or duct system
  • Ventilation – know if it is important to install a dedicated ventilation system

How should the HVAC work?

The principle remains the same. The system requires a compressor, condenser, expansion valve and evaporator. With this in mind, having a large structure poses challenges such as the need for other installment such as cooling and heating towers. Adding these equipment may actually add up to the cost. A quick browse through the floor plan will highlight various parts of the building where it is necessary to install pipes, ducts and water flow source. Careful consideration should be included in putting necessary electrical equipment to work with the electric supply and building requirements. Once installed, HVAC works the same way as any small building that has a simple HVAC networking installed.

HVAC contractor tips

Solutions for large-scale structures and buildings can be added based on what most contractors advise for big buildings.

  • Chillers – source of cool waters to be distributed to air cooling systems via pipes
  • Heaters – these can also help in heating floors or rooms via heating furnaces or radiation heater that can be installed on each floor individually
  • Roof top installations – they are mostly found on rooftops that help funnel the conditioned air into the space
  • Heat pumps – imagine a refrigerator in reverse. The main heat source is pumped with water to allow it to pass through heated walls that take heat from air or water and are carried around the building floor.
