Stacking Evaporator Coil Stages

By May 9, 2018

Stacking Evaporator Coil Stages

In commercial HVAC, you will find several different types of multi-stage evaporator coils: intertwined (shown above), horizontal face split (one coil on top of another), and vertical (side by side).

When staging a horizontal evaporator, pay attention to ensure that stage #1 is on the bottom and stage #2 is on the top. If stage #1 is on top, you risk condensate being pulled off of the coil when the water runs down the wet fins and then hits the dry second stage on the bottom.

By keeping stage #1 on the bottom, the moisture adhesion will stay consistent as condensate drops, no matter if one or both stages are calling.

You can also have this same effect when stage #1 fails, and stage #2 keeps running on a stacked horizontal coil.

HVAC School – For Techs, By Techs

Real training for HVAC ( Heating, Ventilation, Air Conditioning and Refrigeration) Technicians. Including recorded tech training, interviews, diagnostics and general conversations about the trade.

Dominick Guarino from NCI joins the podcast to talk about the High-Performance HVAC Summit, an upcoming event hosted by NCI from April 17–20. The National Comfort Institute (NCI) is a training organization that helps technicians learn crucial skills and succeed through high-performance contracting.

High-performance contracting is based on the mindset of “don’t just promise performance; prove it.” To maximize technicians’ potential, NCI teaches technicians how to test equipment properly and monetize their skills. Techs can then use their knowledge to teach the homeowner about the system and solve problems with sales; they can earn money while being solutions-oriented.

NCI’s High-Performance HVAC Summit is a training event geared toward HVAC business owners and contractors. It started as a membership conference for education and networking, and it has since expanded to include like-minded HVAC professionals from all walks of life. Workshops are led by a mix of contractors and NCI staff, and there are breakout sessions and other various session types.

This year’s High-Performance Summit theme will be “It All Starts With Service.” The four focal points of the workshops will be lead generation through service and maintenance, CO safety, the lead handoff from service to sales, and maintenance agreements. One more session will focus on hands-on testing, called “Low-Performance Town” this year, and there will be a panel about the future of high-performance HVAC.

Dominick and Bryan also discuss:

Dominick and NCI’s history in the industry
High-performance maintenance
Consumers who do their research
The HVACR Training Symposium
High-Performance Summit Awards Banquet
NCI’s collaboration with other industry leaders and organizations

Tips for Server Room Conditioning

Server rooms, sometimes called data rooms, are a somewhat unique situation in the HVAC trade with some special circumstances that should be considered. Here are a few tips for success when working on equipment for these spaces. Note: this article is focused on smaller server rooms that may use conventional or mini-split-type forced air equipment.

A Simple Piping Practice

Although there are various line lift, sizing, and trapping guidelines depending on oil and refrigerant type, there is one guideline we can all understand easily and remember to apply. This guideline is to slope suction lines towards condensing units/compressors. Keeping the suction line sloped toward the compressor, especially with long overhead lines, helps return the […]
