Keep Your Home Warm and Energy Efficient

You can put on a sweater when you are chilly, but when your home gets chilly…that’s a really big sweater! So, how do you keep your home warm? You do this the same way you keep a person warm.

Now, think about that oversized cozy, woolly sweater as insulation. Regardless of the part of the country you live, having the proper R-value of insulation is known to be of great importance. Insulation can be said to be the protective layer between your home and its elements. All exterior walls of a home should be properly insulated. In case you have a room above your garage or in an attic, these are the two places most homeowners commonly overlook for insulation.

It is said that a greater amount of heat is lost through the head, so you shouldn’t forget your hat, but home-wise, don’t forget your roof! Not only does the roof keep rain away; it also prevents rising warm air in your home from escaping outside. Most of the heat stays inside your home and your furnace shouldn’t work so hard so as to keep a comfortable temperature throughout your home.

There is no way you’ll get warm if you are wearing a sweater with so many holes during winter. Similarly, your home can’t get warm if there tiny gaps are present around doors and windows allowing for the exit of warm air out and entry of cold air.

  • Place your hand on the edges of your windows and doors to check if there is any air leaking in and/or out of your home.
  • Frosty or foggy windows are obvious signs that the cold air outside is leaking into the room through the tiny openings around your windows.
  • Put an elastic gasket at the back of the light switches and cover plates of the electrical outlet on the exterior walls to minimize or eliminate loss of warm air.
  • A thermostat that is programmable may be your best option in an extremely cold weather. All you have to do is to program it to the temperature you desire at your desired time and the thermostat will be up and running doing all the work for you. Set the thermostat to your ideal temperature whenever you are at home and awake, and make sure you set it back when you are away from home or asleep.
  • Disregard your existing settings when you have friends or family over— especially if you’ll be making a big dinner in your oven.
  • Take turns to host games nights or potluck dinners with your friends for an amazing way of reducing the energy usage in your home, even if it’s for a night.

So many things are available that you can do to highlight those sources of cold that are entering your home and how to keep your home warm when the winter arrives.

HVAC system Basics for Beginners

Are you a property owner, property manager, aspiring engineer or Tech enthusiast and you do not have the basic knowledge of HVAC systems? If yes, then you are reading the right introductory piece. All you need do is sit back, and pay raft attention.
HVAC refers to Heating, Ventilation and Air Conditioning systems. These systems are an essential part of residential, commercial and industrial buildings. The objective of HVAC systems is to control the circulation of air and moisture within living spaces while maintaining thermal comfort. HVAC system can also be regarded as climate controllers.
In more technical terms, the functions of an effective HVAC system include control of air movement, temperature and moisture control inside an air-conditioned confinement, air filtration and supply of fresh air for the control of carbon dioxide and oxygen levels in a conditioned space. A typical example of HVAC systems is the big air conditional blocks you might on rooftops of offices or apartment blocks.
Over the years, air conditioning has moved from the mere supply of cool air to the effective control of critical parameters such as air movement, temperature, humidity etc.
HVAC systems are of various types with one having its own advantage over the other. These types are:
• Packaged Systems
• Split Systems
• Ductless Split System
• Hybrid Heat Split
The technicalities of these types of HVAC systems will be elaborately discussed in subsequent articles.
Components of a Heating, Ventilation and Air Conditioning System (HVAC)
As a beginner, it is important to be familiar with the various parts of a HVAC system so that in the event of a slight technical complication, you will be able to identify the affected part. The effective functionality of each of the components of a HVAC system relies solely on one another (one must function effectively for the other to work properly). Here is a list of the key components of a HVAC system you must know:
1. Evaporator: this component is saddled with the responsibility of absorbing condenser heat load and ensuring that the HVAC cools properly.
2. Compressor: this component is widely referred to as the soul of HVAC systems; it provides the thrust and energy required to transport refrigerant around the system.
3. Condenser: this component forces out heat build-up inside the refrigerant to the outside air.
4. Thermostatic Expansion Valve (TEV): this device regulates the quantity of liquid refrigerant passing through the evaporator thereby maximising evaporator efficiency.
5. Boiler: this component of HVAC systems is responsible for the heating of water.
6. Duct Systems: A duct system serves as cool or warm air distribution point. It can either be flanged, rectangular or spiral.
7. Evaporator Blower Motor (EBM): this component forces air through the ducts.
8. Condenser Fan Motor (CFM): fan motor rejects heat load and maintains maximum head pressure required for operation of the compressor.
9. Furnace: this component is responsible for the transportation of air into the duct systems from the heat exchanger.
Other components include Chillers, Cooling Towers, pumps, Building Automation Systems (BAS) also referred to as Energy Management Monitoring Systems (EMMS)
