Smart HVAC Technology – An Overview

Posted on 24 April 2018 (0)

About half the energy used in your home is accounted for by your HVAC system. Therefore, an inefficient heating and cooling system will amount to an increase in energy bills.  Putting up an efficient and smart HVAC system will help you to save significantly on energy bills and get more value for your investment. The most recent HVAC systems are embedded with a high level of technology which offers homeowners an immaculate level of remote control. However, remotely controlling your home’s climate requires that a smart HVAC system is in place. This guide offers you some features of a Smart HVAC system.

What is a Smart HVAC system?

A smart HVAC system otherwise referred to as an Advanced HVAC system is an intelligent technology which grants you the ability to remotely gain control of the climatic conditions of your home using a desktop or smart device. This system helps you to gain better control of your central cooling and heating systems. With a few taps on your smart device or PC, you can initiate heating or cooling in your home.

Advanced HVAC systems are sensor-based, internet oriented and they utilise adaptive control strategies to tune capacity, flow rates, temperatures, humidity, etc.

The components of a smart system include a sensor that is directly connected to the condenser and boiler, main control, AC unit, programmable thermostat and the mobile application usable on a smart device. The mobile app will enable you to remotely control our HVAC system from wherever.

 

What makes an HVAC system smart?

Unlike traditional HVAC systems which only allows you to control the temperature of a conditioned space using a control panel or switch, Smart HVAC systems offer a more efficient, more accessible and user-friendly manner to control cooling and heating in your home. Some features that make an HVAC system smart or advanced include:

  • Compressor and Air Handling unit

These two features use up most of the energy in a cooling and heating system. An advanced HVAC system monitors the use of these units and ensures that they only run when there is need.

 

  • Thermostat

Regular thermostats just take readings and adjust temperatures but a smart thermostat does more. It takes humidity and temperature readings and can tell the number of persons present in a particular room at a given time. When there are more people in a room, more heat is generated and otherwise when no one is in the room.

 

  • Air and Ventilation

After a thermostat must have determined the comfort demands of a particular room or rooms, the required volume of air is sent to the room(s) by the ventilation system. The standards for zoning systems demands that if the temperature of a particular zone is too high, air can be withdrawn from that zone and diverted to another zone that is too cold. A smart HVAC system will not only regulate air distribution, it can also notify you if one zone is using up more energy than necessary. A smart system will also detect blocked vents and suggest repair and maintenance schedules.

HVAC systems are the core of cooling and heating within homes and office buildings. Therefore, having an understanding of the fundamental principles of HVAC systems will help you to comprehend the basics of HVAC system operations. To understand the effective control of critical parameters such as air movement, humidity and temperature in a conditioned space, it is essential to be familiar with the processes and fundamental principles of HVAC.
The processes of Heating, Ventilation and Air Conditioning are:
1. Cooling: this is a decrease in temperature achieved by the removal of thermal energy from a conditioned space.

2. Heating: this involves the increase in temperature achieved by the addition of thermal energy to a conditioned space

3. Air Movement: this involves the control, transportation and supply of ample air through the ducts into a conditioned space so that the occupants of the space feel comfortable.

4. Humidifying: this process involves the addition of steam or water vapour to a space to increase the relative humidity of that space.

5. Dehumidifying: this is the opposite of the humidification process as it involves the removal of humidity or water vapour of a space.

6. Ventilating (the V in HVAC): this is a very important process in HVAC. It is the addition of fresh air from the outside to the inside without compromising gas ratios. In other words, it is the process of replacing or exchanging air in any conditioned space to provide high indoor air quality. Ventilation or ventilating involves oxygen replenishment, temperature control, and the removal of smoke, airborne bacteria, excessive moisture, heat, carbon dioxide, dust, and unpleasant smells.

7. Cleaning: the is also an important process in HVAC and it is otherwise referred to as Air Filtration. It involves the removal of smoke, contaminants, pollens and dust from the air inside a conditioned space.

Heat removal from an HVAC system (Cooling)
Removal of heat in simple term means an attempt to cool down. There are numerous practicable methods to get rid of heat from a residential or office building. The commonly known and utilized method is the use of Air Conditioners. This has, however, created a misconception that the use of ACs is the only means of removing heat from a building. To efficiently get rid of heat from a space, a heat pump can also be used. A heat pump offers a lot of advantages over a traditional Air Conditioning unit.
The various types of Air Conditioning Units that can be used for the removal of heat are:
• Split Unit
• Window Unit
• Chilled Water Air Conditioning System
• Direct Expansion ACs
• Hybrid Air Conditioners
• Portable Air Conditioners

Heat Addition to an HVAC system (Heating)
In HVAC systems, heat generation can take different forms. In some set-ups, furnaces are used while in some, boilers are employed. Furnaces generate heat through burning of materials and supplies the heat through the duct system. Boilers employ oil and gas to raise the temperature of water while a furnace utilizes propane or natural gas. Another heating option is the use of Hydronic Heating Systems (HHS). HHS makes use of underground pipes, made of flexible tubes, filled with glycol or water solution

Five Signs your Residential HVAC Unit Needs Repairs

Posted on 02 November 2017 (0)

No matter where you live or your location in the United States, heating, and cooling systems play a crucial role when it comes to maintaining a comfortable indoor environment. Most parts of the country experience extremely high summer temperatures and low winter temperatures which is why homeowners have to invest in HVAC units. To ensure your air conditioner functions and works well when needed most, you must pay close attention to the indicators of system failure.

So, how can you tell if there’s a problem with your air conditioning unit? We both know that you’re not an expert or experienced in this area which means it can be tough to know when there’s a problem. At times, you might think your HVAC system is working fine, yet it has complications. It’s recommended to schedule an A/C repair regularly, especially before or after summer, to make sure your equipment is working at maximum efficiency. Here are some of the signs that indicate it’s time to repair your air conditioner.

Squealing or Grinding Noise

Well, there are times when your air conditioner will sound like a horror movie. That’s a sign of a problem. Any weird noise could indicate a problem in your motor bearings or broken belts. A squealing sound would indicate your equipment needs lubrication in some of its metal components. You shouldn’t wait for your system to stop working before you look for an HVAC technician.

Poor Air Flow

Some of the reasons why your air conditioner has not been producing air flow include a failing compressor or a blocked ductwork. This problem can be detected if the temperature in each of your rooms is different.

Thermostat Problems

How will you know if there’s a problem with your thermostat? If in the past few days, some of your rooms seem to be receiving air while others don’t, there could be a problem with your system’s thermostat. In such cases, you may need to contact a trained technician to either repair or replace your thermostat so that it can start producing consistent temperatures.

The presence of Moisture where it shouldn’t be

If you detect a leakage or moisture near or around your air conditioner, chances are there’s a problem with the drain tube. At times, the problem could be as a result of a leaking refrigerant. It this is the case, you must have a technician make the necessary repairs as soon as possible since refrigerant leaks pose a health risk to you and your family.

Strange Odors

If you notice a musty smell coming from your HVAC unit, it is likely there’s mold growth within or around the system’s components. Note that the air coming from your system’s vent is supposed to be cool and crisp. There are two possibilities is there’s a strange odor coming from your unit; a burnt out wire insulation or mold growth within the system. Contact an experienced HVAC contractor to inspect your system and identify the source of the unusual smells.  http://www.newportricheyairconditioner.com/
