The Professor: The Importance of the Condenser

Condensers perform three vital functions, so keep them clean and damage-free

June 6, 2016

One of the main components of any refrigeration or air conditioning system is the condenser. As its name indicates, the condenser condenses refrigerant vapor sent to it from the compressor. However, the condenser also performs other important functions, too.

An Introduction to the Combustion Process

What, exactly, is energy and heat transfer?

Whatever our comfort zone may be, if we do not have some understanding of the combustion process and heat transfer, neither method has much meaning or value.

Heat Transfer: Nature Versus Math

Formulas and Assumptions Don’t Always Predict what Happens

The following formula has been around the North American hydronics industry for a long time: Btuh = 500 x gpm x delta T. It can be used to estimate the rate of heat transfer into or out of a device that has a stream of water flowing through it at a known flow rate, and with a measured temperature change between the inlet and outlet of that water stream.

Papers Ponder Ammonia, Heat Transfer

Ongoing Developments Regarding Natural Refrigerants and Continued Commitment to Refrigeration Basics

Heat Transfer Fundamentals (STM 301) presented by Spirax Sarco.

On Demand As AI workloads and high-density computing push traditional cooling methods to their limits, the data center industry is accelerating the adoption of next-generation HVAC technologies.

In this session, we will cover how to design VRF systems for the U.S. market using new A2L refrigerants. These systems provide an advanced zoning solution by using inverter technology to deliver precise heating and cooling control across multiple zones and spaces.
