Humidification Basics Part 4: How to Calculate Humidification Load for Natural and Mechanical Ventilated Spaces

How do we determine how much moisture should be added to the air for a given application? In other words, how do we calculate the humidification load for a given building?

The basis of this calculation is the same, whether you intend on using natural, mechanical, or economizer cycle ventilation. Natural and mechanical ventilation methods are virtually the same, which is why....

Humidification Basics Part 3: Psychrometrics Made Easy (Well….Sort of)

What is psychrometrics?

It’s a big and intimidating word to be sure and the common definition, the study of the physical and thermodynamic properties of gas-vapor mixtures, doesn’t make it much less so. But we’re going to break it down for you in a way that is both simple and practical with regard to HVAC and ...

Humidification Basics Part 1: Why Humidify?

Ever hear the phrase, “It's not the heat, it's the humidity”?

In the commercial HVAC industry, we’d like to reshape that idiom to, “It’s not just the heating and the cooling, but also the amount of moisture in the air that impacts comfort, health, building materials, building content, medical procedures, and production processes and quality.” 

But admittedly, that’s a mouthful. 

Suffice to say that properly controlled humidification is an essential part of HVAC design, which is why we’ve decided to dedicate an entire series to the subject, starting with why we need to humidify spaces in the first place....

Parallel Pumping in Condenser Applications: Part 5 of 5

Over the last few weeks the we’ve looked at pumping issues with multiple condensers and pumps.  We have received questions about the topic, including these two:

Why do I need cooling tower outlet On-Off valves if I have an equalizing line?

Why do we see outlet On-Off valves on almost all jobs in North Carolina and only half the jobs in Michigan and Northern Ohio?
