systems. The effects of non-condensable gasses, in a refrigeration
system,...
A refrigerant distributor is a device connected to the outlet of an
expansion valve when paired with a multi-circuit evaporator. The
outlet of the distributor is machined to accept tubing...
To obtain long term system life, it is important to keep
contaminants to a minimum. This is particularly true of a heavy
duty application such as a heat pump. Therefore, all heat pumps
should have at...
Manufacturers have been successfully applying Parker Sporlan
Thermostatic Expansion Valves on Heat Pump Applications for many
years. Parker Sporlan's large diaphragm and durable welded element
result...
Working in the HVAC and Refrigeration industry there are many times
when you are going to have applied torque when working on a
particular job. In this blog, we help you understand the basics...
Today more and more applications are utilizing “heat reclaim” as a
means of providing a supplementary or even a primary heat source.
Heat reclaim can significantly lower energy costs. Heat reclaim...

service is covered in Bulletin 90-31. This Climate Control...
As most of us know, sizing solenoid valves for split condensers
seem to be more of an art, than a science. Many tangibles affect
the calculations. This Climate Control blog will provide...
Customers have complained of hydraulic hammering noises on heat
pump systems for years. Field people refer to it as the
“knock-knock” noise. The complaints usually surface at the end of
the heating...

HVACR technician will find useful. Oil types Mineral – a by-product
in the distillation of crude oil to produce gasoline. Mineral...
Most supermarket refrigeration equipment breakdowns are repeat
problems. When responding to refrigeration service calls at
supermarkets, refrigeration technicians immediately play...
A large percentage of compressor failures in low-temperature
vapor-compression refrigeration system applications originate from
overheating. Typical compressor capacity rating data is based on...
Monitoring the acid level in a refrigeration or air conditioning
system is of the utmost importance. Contaminants such as water and
air are important factors in the formation of acids in the...
Here is information on Psychrometrics that should help remind the
HVACR technician what this subject is all about... with perhaps a
few tidbits the tech may not have known! Psychrometrics: the...
Superheat is the temperature of refrigerant gas above its saturated
vapor (dewpoint) temperature. Superheat as it relates to
thermostatic expansion valves, can be broken down into three
Superheat...
