This course is designed to reinforce concepts regarding elements commonly found on residential, commercial, and industrial prints. Explanation of the different sections of the print and commonly used abbreviations and symbols shall be covered. Approximately 3 hours.
Covers the tools, materials, techniques, and safety information required to become a competent at joining copper through brazing.
Cranes are an integral part of most construction jobsites. Coordination between the riggers and the operator is important to insure a safe work environment and the timely completion of the job. Most communication between the riggers is via hand signals. The most common hand signals for a stick type of crane will be covered in this class. (Possible hands on)
Firestopping is the returning of a fire rated wall or floor to its original design fire rating, after being penetrated by pipes, conduit, wiring, and ductwork. In spite of the common misconceptions this is a lot more than just the application of fire caulk. The penetrations or joints in a building must be closed based on UL approved systems from different manufacturers. The bulk of this course is to learn to read the different manufacturers firestop guides so that the products may be installed properly in a cost effective manner.
Covers the laws of physics that govern air conditioning and refrigeration. Beyond this other topics of discussion will include, pressure, vacuum, temperature, types of heat, types of heat transfer, and general industry language.
We will discuss the basic components of the closed direct expansion refrigeration system. The purpose and basic operation of each of the components and how they relate and interact with each other.
The different types of metering devices; cap tube, fixed metering device, automatic expansion valve, thermostatic expansion valve, and electronic expansion valve will be discussed. Included will be some troubleshooting information.
The heart and soul of any air conditioning system. The different types of compressors found in the industry will be covered. A good deal of time will be spent on compressor failures and the causes. The class will finish up with a diagnostic tear down of a compressor to show this valuable diagnostic technique.
This class will cover the proper piping of an HVAC/R installation. This class is designed to take the mystery out of the piping practices to insure a proper and efficient installation. Includes a discussion of hot gas bypass for low load applications.
(Added to one of the electrical classes)
Covers the necessity for defrosting medium and low temp refrigeration systems. The different components used, proper set-up of the controls and troubleshooting techniques.
Heat pumps have come a long ways from the 1960's. We will separate the myths from the facts. Includes terminology, set-point and a discussion of the different types of heat pump defrost controls.
This class takes all of the information in the previous modules and brings it all together. The attendee will be given valuable information about the design operating parameters of the closed system. This will be followed by a discussion of how these parameters relate to malfunctioning machines.
(Attendees must have completed all of the previous HVAC modules to attend this class)
On The attendee will be able to take the information garnered in the previous HVAC modules and apply it hands on in a controlled environment. Very informative (hand tools are required, a list will be supplied) (Attendees must have completed all of the previous HVAC modules to attend this class)
Covers basic electricity, its history, the 8 laws of electricity, and the importance of ohms law.
A discussion of the components in a basic circuit. The class will then cover the components of a properly drawn schematic showing an understanding of the flow of electrons in the circuit. Special emphasis will be placed on switches and loads and the interaction of all of the components. The attendee will come out of this class learning not only how to read a schematic but how to draw one as well.
This module will cover single, two, and 3 phase power distribution. Wye and Delta wound transformers and some basic NEC code information revolving around proper wire connections for a safe installation.
A very in-depth discussion on motors with special emphasis on the different types of single-phase motors including different start components.
Two phase and three phase motors will be discussed at this time, followed up by and informative discussion of trouble shooting systems with PC boards.
All of the information garnered in the previous HVAC Electrical modules will be applied in a controlled setting. (prerequisite - HVAC Mods I through V must have been attended)
A complicated hydronic heating system made simple. P/S Pumping is a unique way to combine hydronic zoned system operating at different temperatures.
If you can't tie a knot - tie a lot! Many people are uncomfortable tying off tools and other things with ropes, this course was designed to make rope and knots simple and understandable. The attendee will learn to tie a; square knot, thief's knot, figure eight, figure eight on a bite, clove hitch, a bowline, and quite a few more.
The proper methods used to install a fire damper in a fire rated wall to meet the code requirements.
Covers the tools, materials, techniques, and safety information required to become a competent at joining copper through soldering.
Steam heat is fast becoming a lost art. Many people look at steam heating and think it is complicated when in reality it is very simple. We will cover enough of the basics to make most heating mechanics comfortable.
Variable Frequency Drive for motor speed control is relatively new. We will discuss the ways that motor speed was controlled prior to VFD's and then get into how VFD's function and their control followed up by the problems associated with these wonderful electronic magic boxes.
