HVAC Controls Building Automation | Heating & Cooling Control

HVAC Controls Building Automation  - Modern buildings use DDC controls for building automation systems. Building automation systems offer energy savings because they are energy management systems. These systems allow management to automatically control many processes involved with HVAC systems, lighting, and emergency systems. The systems are generally hooked up to the internet so monitoring and control can be done worldwide.

Rooftop Economizer CO2 | HVAC Control

HVAC Rooftop Economizer - CO2 ControlRooftop Economizer CO2 | HVAC Control

This damper is part of a free cooling system for a rooftop economizer. It is part of an economizer damper system which allows free outside air cooling when the outside air temperature and humidity are ideal. This economizer also works on CO2 control so that if the CO2 levels inside the space rise above a set point the economizer damper opens allowing fresh outside air into the space while venting the air laden with CO2 to the outside.

Building Automation Systems | HVAC Control

Building Automation Systems – HVAC ControlMany people wonder what Building Automation Systems (BAS) do. BAS is mainly used in commercial HVAC control systems and energy management system applications. Building Automation itself is an energy management system which saves management companies and building owners by efficiently controlling air conditioning and heating comfort and process systems. BAS is where mechanical and electrical systems and equipment are joined with microprocessors that communicate with each other and possibly to a computer. This computer and controllers in the building automation system can be networked to the internet or serve as a stand alone system for the local peer to peer controller network only. Additionally, the BAS controllers themselves do not need a computer to process the control functions as the controllers have their own internal processors.

Tankless Water Heaters

Tankless Water Heater

I have been transformed into a believer of tankless water heater systems. Anyone who has read the About Us page at High Performance HVAC along with my friends and family and some fans of the site know that I moved to Ukraine about a year ago for professional reasons. When I first arrived in Ukraine it took a while for me to adapt to the culture, language, services, and way they do things here. Power failures, water outages, and occasionally the natural gas outages are quite frequent here although it is tolerable and a minor inconvenience. Many of the outages occur at night when many people are sleeping but occasionally during the day when you need it. I must include that this has been a big adventure and I have learned much and to tell you if you are living in the States or Western Europe you have it good but that doesn’t mean Ukraine is bad it just means they are little behind and hopefully will quickly catch up. I have not seen a standard water heater here like the common water heaters with tanks in the States. All the systems I have seen here are tankless including the water heaters in the apartment I rented and now in the house where I live. I am sure there are tank-type water heaters here like in the States but I have not seen them yet.

Air Conditioner Ductwork Leaks

Red Arrow Shows a Duct Work Leak in a Brand New Installed Duct System

A good consideration when replacing the air conditioning system is the duct work. Duct work seems to be the most ignored part of an HVAC system but is a very important consideration in this age of new technology and higher energy efficient equipment being developed and manufactured. You can have the most energy efficient engine but if its in an old 60 or 70’s model car your efficiency is going to suffer. The same is true with HVAC systems. You can have the most energy efficient compressor available on the market but if your duct work is leaky or your house or business is not properly insulated that high efficient system you just spent big dollars on is wasted money. For more insight on HVAC ductwork see the High Performance HVAC Ductwork Page.
